在Oracle 9i R2版中引入的MERGE语句通常被称作“更新插入”(upsert),因为使用MERGE可以在同一个步骤中更新(update)并插入 (insert)数据行,对于抽取、转换和载入类型的应用软件可以节省大量宝贵的时间,比如向数据仓库中加载数据,数据仓库中没有的数据行可以插入到数据仓库中,而已经存在的数据行也同时被更新。

在MERGE语句引入的时候,需要同时使用一条UPDATE和一条INSERT语句,顺序也是固定的(先使用UPDATE语句,然后是INSERT 语句)。如果您只需要使用其中的某一条一句,您只需要使用现有的INSERT或者UPDATE语句,而不必使用MERGE语句,而删除数据可以使用 DELETE语句。

在Oracle 10g R1版中,MERGE语句发生了变化,UPDATE或INSERT语句不再是必须的,而是可选项,您可以两者都用也可以都不用,而且,UPDATE语句也具备了DELETE的功能,您可以在同一个步骤中对现有的有效记录进行升级并清理废弃的记录。

列表A创建了一个表格列出现有项目:项目号码、标题、开始日期、进度完成比例以及员工对项目的响应,还创建了一个事务表格使用MERGE语句进行升级批处理。

列表A

DROP TABLE open_projects;

DROP TABLE project_updates;

CREATE TABLE open_projects

(pno NUMBER(6) PRIMARY KEY,

title VARCHAR2(40),

startdate DATE,

pctdone NUMBER(3),

empno NUMBER(6)

);

INSERT INTO open_projects VALUES

(10, "Inventory servers", "08-JAN-07",0, 206);

INSERT INTO open_projects VALUES

(20, "Upgrade Oracle on SRV01","15-JAN-07", 0, 206);

INSERT INTO open_projects VALUES

(30, "Conduct skills assessment","22-JAN-07", 0, 210);

CREATE TABLE project_updates

(action CHAR(1),

pno NUMBER(6),

pctdone NUMBER(3),

empno NUMBER(6)

);

INSERT INTO project_updates VALUES

("C", 10, 50, 214);

INSERT INTO project_updates VALUES

("D", 20, NULL, NULL);

COMMIT;

一个典型的MERGE语句从识别表格开始执行升级,而且对现有的记录进行筛选测试:

MERGE INTO open_projects op

USING project_updatespu

ON (op.pno = pu.pno)

...

表格open_projects会接受更新的数据,而project_updates表格则不会改变,如果项目号码(pno)在两个表格中都一样,那么数据行则被认为是相同的。

MERGE语句剩下的部分是更新语句,以及DELETE WHERE语法。

...

WHEN MATCHED THEN

UPDATE SET pctdone = pu.pctdone,

empno = pu.empno

DELETE

WHERE pu.action = "D";

列表B展示了MERGE语句运行前后的表格情况。

第一个事务对第10号项目进行了改变(操作‘c"),项目完成比例从0变成了50,项目员工人数变成了214人;第二个事务产出了第20号项目, “随后”的列表展示了删除后的状态,而project_updates表格没有发生改变。这个例子展示了这些语句并不是必须的,而且在MERGE语句中也并不需要使用INSERT语句。

hibernate3.0以上使用merge()来合并两个session中的同一对象

a different object with the same identifier value was already associated with the session

一个经典的hibernate错误:a different object with the same identifier value was already associated with the session xxxx

hibernate3.0以上使用merge()来合并两个session中的同一对象

具体到我自己的代码就是

public Object getDomain(Object obj) {

getHibernateTemplate().refresh(obj);

return obj;

}

public void deleteDomain(Object obj) {

obj = getHibernateTemplate().merge(obj);

getHibernateTemplate().delete(obj);

}

they become merged in the sea

不管采不采纳,我的回答就在这里这里的merged 不是动词,是形容词,是ed 后缀的形容词因为become 是联系动词,后面跟形容词,而这个ed 的后缀,不是仅仅是动词过去式,你得判断一下比如,worried,excited,relaxed这些词,有时候是过去式,有时候是形容词,你得根据搭配,来进行判断词性

su怎么把两个文件合并

su是一个Linux下的命令,用于切换到其他用户。而将两个文件进行合并,可以使用多种工具,如cat、join、paste等,具体使用哪种工具需要根据文件的特点和需求进行选择。如果要使用cat命令进行合并两个文件,那么可以使用以下命令:```cat file1.txt file2.txt > merged.txt```其中,">"表示重定向输出到指定的文件中。上面的命令将file1.txt和file2.txt两个文件中的内容合并到merged.txt文件中。如果要使用join命令进行合并两个文件,那么需要保证两个文件中的内容有相同的键值。使用命令如下:```join file1.txt file2.txt > merged.txt```上面的命令将file1.txt和file2.txt两个文件中相同的键值所在的行合并到merged.txt文件中。如果要使用paste命令进行合并两个文件,那么可以将两个文件每行的内容合并成一行。使用命令如下:```paste file1.txt file2.txt > merged.txt```上面的命令将file1.txt和file2.txt两个文件中每行的内容合并到merged.txt文件中,每行的内容使用制表符分隔。综上所述,合并两个文件可以使用cat、join、paste等工具,并且使用不同的工具需要给定不同的文件格式和输入方式。

Gradually the river grows wider, the banks recede, the waters flow more quietly,

这段话在大学英语里属于并列成分构成的排比句。首先the river grows wider, the banks recede, the waters flow more quietly是并列的主谓结构,接着是and连接的一个并列句,without any visible break是插入语,看句子时可以忽略它,不影响句子结构,they become merged in the sea, and painlessly lose their individual being. 是and后的另一个句子,其中又包含两个并列的结构,become merged是系表结构,being是现在分词作宾语。就这么多了,希望对你有帮助。

怎么将hello+world加密成hweolrllod?

如果你想将字符串 "hello" 和字符串 "world" 合并为 "hweolrllod" 这样的字符串,你可以使用以下步骤来实现:创建一个空字符串变量,用于存储合并后的字符串。使用双重循环来遍历两个字符串。每次循环时,将两个字符串中的一个字符添加到空字符串变量中。在双重循环结束后,将空字符串变量返回。例如:public String merge(String s1, String s2) {String mergedString = "";for (int i = 0; i < s1.length(); i++) {mergedString += s1.charAt(i);if (i < s2.length()) {mergedString += s2.charAt(i);}}return mergedString;}调用这个方法并传入 "hello" 和 "world" 作为参数,将会返回字符串 "hweolrllod"。请注意,这只是一种可能的实现方式。你可以使用其他方式来实现相同的功能。

根据我的经验是,你在合并单元格时,重复使用了已经被合并单元格的单元格. 也就是说,你的A18,B18 这两个单元格至少其中一个被之前的代码使用合并过单元格了,不能再次进行单元格操作.

spss16.0横向合并数据库怎么有时候不能按ID号合并?

两个数据库(.sav文件)按照关键变量排序(关键变量必须没有重复,每个变量值能够明确的指出一个特定的Case;也可以使用一组变量作为关键变量)两个数据库文件的变量类型和变量长度要一致!变量类型和长度可以在VARIABLES VIEW中查看和修改然后就是菜单中选择: Data Merge Files Add Variables...之后按照你原来的操作做就可以了,这样就不会出现“变量的类型或者长度不对”的错误了具体的可以参考SPSS帮助文档Add Variablesmerging data files,merging data files,merging data filesfiles with different variables,files with different variables,files with different variablesfile transformations,file transformations,file transformationsmerging data files,merging data files,merging data fileskeyed table,keyed table,keyed tableAdd Variables merges the active dataset with another open dataset or SPSS-format data file that contains the same cases (rows) but different variables (columns). For example, you might want to merge a data file that contains pre-test results with one that contains post-test results.Cases must be sorted in the same order in both datasets. If one or more key variables are used to match cases, the two datasets must be sorted by ascending order of the key variable(s). Variable names in the second data file that duplicate variable names in the active dataset are excluded by default because Add Variables assumes that these variables contain duplicate information.Indicate case source as variable. Indicates the source data file for each case. This variable has a value of 0 for cases from the active dataset and a value of 1 for cases from the external data file. Excluded Variables. Variables to be excluded from the new, merged data file. By default, this list contains any variable names from the other dataset that duplicate variable names in the active dataset. Variables from the active dataset are identified with an asterisk (*). Variables from the other dataset are identified with a plus sign (+). If you want to include an excluded variable with a duplicate name in the merged file, you can rename it and add it to the list of variables to be included.New Active Dataset. Variables to be included in the new, merged dataset. By default, all unique variable names in both datasets are included on the list.Key Variables. If some cases in one dataset do not have matching cases in the other dataset (that is, some cases are missing in one dataset), use key variables to identify and correctly match cases from the two datasets. You can also use key variables with table lookup files. The key variables must have the same names in both datasets. Both datasets must be sorted by ascending order of the key variables, and the order of variables on the Key Variables list must be the same as their sort sequence. Cases that do not match on the key variables are included in the merged file but are not merged with cases from the other file. Unmatched cases contain values for only the variables in the file from which they are taken; variables from the other file contain the system-missing value.Non-active or active dataset is keyed table. A keyed table, or table lookup file, is a file in which data for each "case" can be applied to multiple cases in the other data file. For example, if one file contains information on individual family members (such as sex, age, education) and the other file contains overall family information (such as total income, family size, location), you can use the file of family data as a table lookup file and apply the common family data to each individual family member in the merged data file.To Merge Files with the Same Cases but Different Variables Hide details To Merge Files with the Same Cases but Different Variables Open at least one of the data files that you want to merge. If you have multiple datasets open, make one of the datasets that you want to merge the active dataset. From the menus choose: Data Merge Files Add Variables... Select the dataset or SPSS-format data file to merge with the active dataset.To Select Key Variables Select the variables from the external file variables (+) on the Excluded Variables list. Select Match cases on key variables in sorted files. Add the variables to the Key Variables list.The key variables must exist in both the active dataset and the other dataset. Both datasets must be sorted by ascending order of the key variables, and the order of variables on the Key Variables list must be the same as their sort sequence

Merge modules是什么啊?

以下来自GOOGLE网页翻译结果:合并模块 Merge modules provide a standard method by which developers deliver shared Windows Installer components and setup logic to their applications.合并模块提供了一个标准的方法,通过它,开发人员提供共享的 Windows Installer组件和安装到他们的应用程序的逻辑。 Merge modules are used to deliver shared code, files, resources, registry entries, and setup logic to applications as a single compound file.合并模块被用来作为一个单一的复合文件的应用程序提供的共享代码,文件,资源,注册表项,并设置逻辑。 Developers authoring new merge modules or using existing merge modules should follow the standard outlined in this section.开发人员创作新的合并模块或使用现有的合并模块应遵循本节所述的标准。 A merge module is similar in structure to a simplified Windows Installer .msi file .合并模块在结构上类似于一个简化的Windows Installer 。msi文件 。 However, a merge module cannot be installed alone, it must be merged into an installation package using a merge tool.但是,不能单独安装合并模块,它必须合并成一个安装使用合并工具包。 Developers wanting to use merge modules must obtain one of the freely distributed merge tools, such as Mergemod.dll, or purchase a merge tool from an independent software vendor.想要使用合并模块的开发人员必须获得自由分发的合并工具之一,如现在Mergemod.dll,或购买一个从一个独立的软件供应商的合并的工具。 Developers can create new merge modules by using many of the same software tools used to create a Windows Installer installation package, such as the database table editor Orca provided with the Windows Installer SDK.通过使用许多相同的软件工具,用于创建一个Windows Installer安装包,如提供的数据库表编辑器与Windows Installer SDK的Orca,,开发人员可以创建新的合并模块。 When a merge module is merged into the .msi file of an application, all the information and resources required to install the components delivered by the merge module are incorporated into the application"s .msi file.当合并模块合并成一个应用程序的。msi文件,安装合并模块提供组件所需的所有信息和资源纳入到应用程序的。msi文件。 The merge module is then no longer required to install these components and the merge module does not need to be accessible to a user.然后合并模块不再需要安装这些组件的合并模块不需要用户访问。 Because all the information needed to install the components is delivered as a single file, the use of merge modules can eliminate many instances of version conflicts, missing registry entries, and improperly installed files.因为安装组件所需的所有信息是作为一个单独的文件交付,使用合并模块,可以消除许多情况下,版本冲突,丢失的注册表项,安装不当的文件。 希望能帮到您,谢谢。

新概念英语第四册美音版011:How to grow old

Lesson 11 How to grow old 第11课 如何安度晚年 First listen and then answer the following question. 听录音,然后回答以下问题。 What, according to the author, is the best way to overcome the fear of death as you get older? 根据作者的看法,什么是克服死亡恐惧的途径? Some old people are oppressed by the fear of death. 有些老年人因为怕死而感到烦恼。 In the young there is a justification for this feeling. 青年人有这种感觉是情有可原的。 Young men who have reason to fear that they will be killed in battle 有理由害怕自己会死在战场上的年轻人, may justifiably feel bitter in the thought 想到自己被剥夺了生活所能给予的最美好的东西时, that they have been cheated of the best things that life has to offer. 感到痛苦,这是可以理解的。 But in an old man who has known human joys and sorrows, 可是老年人已经饱尝了人间的甘苦, and has achieved whatever work it was in him to do, 一切能做的都做了, the fear of death is somewhat abject and ignoble. 如果怕死,就有点儿可怜又可鄙。 The best way to overcome it--so at least it seems to me-- 克服怕死的办法 -- 至少在我看来是这样 -- is to make your interests gradually wider and more impersonal, 就是逐渐使自己的兴趣更加广泛,逐渐摆脱个人狭小的圈子, until bit by bit the walls of the ego recede, 直到自我的围墙一点一点地倒塌下来, and your life becomes increasingly merged in the universal life. 自己的生活慢慢地和整个宇宙的生活融合在一起。 An individual human existence should be like a river-- 个人的存在应该像一条河流, small at first, narrowly contained within its banks, 开始很小,被紧紧地夹在两岸中间, and rushing passionately past boulders and over waterfalls. 接着热情奔放地冲过巨石,飞下瀑布。 Gradually the river grows wider, the banks recede, the waters flow more quietly, 然后河面渐渐地变宽,两岸后撤,河水流得平缓起来, and in the end, without any visiblebreak, they become merged in the sea, 最后连绵不断地汇入大海, and painlessly lose their individual being. 毫无痛苦地失去了自我的存在。 The man who, in old age can see his life in this way, 上了年纪的人这样看待生命, will not suffer from the fear of death, 就不会有惧怕死亡的心情了, since the things he cares for will continue. 因为自己关心的一切事件都会继续下去。 And if, with the decay of vitality, weariness increases, 再者,随着精力的衰退,老年人的疲惫会增长, the thought of rest will be not unwelcome. 有长眠的愿望未尝不是一件好事情, I should wish to die while still at work, 我希望工作到死为止, knowing that others will carry on what I can no longer do, 明白了有人会继续我的未竟事业, and content in the thought that what was possible has been done. 想到能做的事都做了,也就坦然了。

Android Jacoco覆盖率统计配置

Android Jacoco 覆盖率统计Gradle配置,包括生成本地单元测试报告,仪器单元测试报告,合并两种测试的报告,合并两种测试的执行数据并在AndroidStudio的编辑器中查看每一行的覆盖率情况。 这里我们仅仅从Gradle任务来说,不考虑 AndroidStudio/IDEA。 对于本地单元测试来说,原先有一个 testDebugUnitTest 的测试任务,如果不做配置,该任务只会生成测试通过情况的报告。只要应用 jacoco 插件,然后运行 testDebugUnitTest 任务时,就会同时生成jacoco覆盖率统计 执行数据文件 。 之所以能这样是因为 jacoco 插件会给所有 Test 类型的任务添加 jacoco 的配置。 可以通过如下方式输出其执行数据文件路径: 执行情况如下: 仪器单元测试覆盖率数据的统计需要打开 testCoverageEnabled 开关,然后会有一个 createDebugCoverageReport 的任务生成,同时也会生成html的报告。 连接设备执行该任务即可生成对应的执行数据文件及对应的覆盖率报告。 通过在build.gradle中添加如下配置可以在执行时输出其执行数据文件在本机的位置: 然后执行 createDebugCoverageReport , 输出如下 : 通过以上信息我们可知: 由于androidTest 已经生成了html报告,接下来我们需要要为我们的本地单元测试生成HTML报告。 要生成html报告,我们需要一个类型为 JacocoReport 的任务,我们在gradle 中添加如下配置,用于生成 jacocoTestDebugUnitTestReport 任务 添加之后 sync gradle,即可生成一个 jacocoTestDebugUnitTestReport 的任务,执行它即可生成测试报告,生成的测试报告位于: build/reports/jacoco/jacocoTestDebugUnitTestReport 中。 下图就是我们生成的报告,可以看到StringUtils已经能够统计覆盖率了。而MainActivity还没有数据。 我们已经可以生成本地单元测试的覆盖率报告,现在我们需要生成androidTest + test 的合并报告。 之前我们已经知道: 现在我们要做的是将它们合并,但是我们的合并并不是针对html报告,而是针对execution数据。 让我们添加如下配置来生成一个合并报告的gradle任务: 这样,我们便有了一个 mergedJacocoDebugTestReport 的任务,执行后即可在 build/reports/jacoco/mergedJacocoDebugTestReport/html 目录中找到我们的 report 。 现在可以看到,我们的MainActivity(AndroidTest)及StringUtils(test)可以在一份报告中显示覆盖率数据了。 到现在为止,我们已经生成了HTML版本的合并报告,并且可以在其中看到源码没一行覆盖的情况。 但是,我们希望能够在AndroidStudio的编辑器中显示覆盖率的情况,向下面这样: 实际上,我们可以通过AndroidStudio的 Menu-Run-Show Covarage Data 加载 execution 文件,然后在AndroidStudio中显示覆盖率数据。 执行的数据文件位于类似如下目录 : 但是这里有两个问题: 现在,让我们添加一个合并任务: 执行之后位于: build/jacoco/mergeJacocoDebugExecution.exec , 通过AndroidStudio 加载之后,显示如下,两种测试的结果已经合并显示了。 请参考: AndroidTestSample/build.gradle.kts at main · hanlyjiang/AndroidTestSample (github.com)

如何合并两个Docker 镜像

当想让一个容器做两件事情,或者使一个Docker镜像包含来自两个不同镜像的依赖库时,就需要知道每个镜像的Dockerfile。本文介绍了如何通过docker history命令来对Docker镜像进行反向工程,得到它们的Dockerfile,并组织到一个Dockerfile里然后build,从而实现想做的事情。常言道,“不要重复发明轮子!”在使用Docker时,构建自己的镜像之前,最好在Docker Hub寻找一些可以直接使用的镜像做练习。把软件架构分布到一系列容器中,每一个容器只做一件事情,这样的效果非常好。构建分布式应用的最好的基石是使用来自Docker Hub的官方镜像,因为可以信任它们的质量。在某些情况下,可能想让一个容器做两件不同的事情。而在另外一些情况下,可能想让一个Docker镜像包含来自两个不同镜像的依赖库。如果有每个镜像的Dockerfile,这是非常简单的。将它们组织到一个Dockerfile里然后build就行。然而,大多数时间都在使用Docker Hub上准备好的镜像,不会有它们的源Dockerfile。我花时间找一个可以合并(或flatten)两个不同Docker镜像的工具,当然没有它们的Dockerfile。也就是说在找一个能做下面这件事的东西:image 1 -- ---> merged_image_12 /image 2 --此前在GitHub上有两个相关的讨论(1、2),尽管它们都被关闭了。这可能吗?那么,是否存在工具能够像这样做吗:docker merge image2 image2 merged_image?没有!你甚至不可以用下面的方式来构建Dockerfile:FROM image1FROM image2简而言之,在一个Dockerfile里不能有多个基础镜像。但是我需要这个功能!唯一的解决办法是取得这些镜像的Dockerfile,然后把它们组织到一个文件中,再进行构建。那么,我能在Docker Hub上获得一个镜像的Dockerfile吗? 幸运的是可以。它不能离线获取(译注:原文是online,但显然online时对于来自GitHub的自动构建镜像是可以直接获取的),但是你可以使用docker history命令,通过反向工程获取。怎么来使用?在你的机器上使用docker pull从Docker Hub下载镜像。docker pull image1docker pull image2然后使用docker history来取得构建这两个容器时运行的命令。docker history --no-trunc=true image > image1-dockerfiledocker history --no-trunc=true image2 > image2-dockerfile接下来打开这两个文件,你可以看到每个镜像的命令堆栈。这是因为Docker镜像通过层(阅读更多)的方式来构建。即你在Dockerfile中键入的每一个命令所构建的新镜像,都是在之前的命令产生的镜像之上。所以你可以对镜像进行逆向工程。限制不能对镜像进行反向工程的唯一场景,是镜像的维护者在他的Dockerfile中使用了ADD或COPY命令。你会看到这样一行:ADD file:1ac56373f7983caf22 或 ADD dir:cf6fe659e9d21535844 这是因为不知道维护者在他自己的机器上,包括镜像里使用了什么本地文件。

The story of Thanksgiving 感恩节is basically the story of the Pilgrims and their thankful community feast at Plymouth, Massachusetts. The Pilgrims, who set sail from Plymouth, England on a ship called the Mayflower on September 6, 1620, were fortune hunters, bound for the resourceful "New World". The Mayflower was a small ship crowded with men, women and children, besides the sailors on board. Aboard were passengers comprising the "separatists", who called themselves the "Saints", and others, whom the separatists called the "Strangers". After land was sighted in November following 66 days of a lethal voyage, a meeting was held and an agreement of truce was worked out. It was called the Mayflower Compact. The agreement guaranteed equality among the members of the two groups. They merged together to be recognized as the "Pilgrims." They elected John Carver as their first governor. Although Pilgrims had first sighted the land off Cape Cod, Massachusetts, they did not settle until they arrived at a place called Plymouth. It was Captain John Smith who named the place after the English port-city in 1614 and had already settled there for over five years. And it was there that the Pilgrims finally decided to settle. Plymouth offered an excellent harbor and plenty of resources. The local Indians were also non-hostile.But their happiness was short-lived. Ill-equipped to face the winter on this estranged place they were ravaged thoroughly. Somehow they were saved by a group of local Native Americans who befriended them and helped them with food. Soon the natives taught the settlers the technique to cultivate corns and grow native vegetables, and store them for hard days. By the next winter they had raised enough crops to keep them alive. The winter came and passed by without much harm. The settlers knew they had beaten the odds and it was time to celebrate.They celebrated it with a grand community feast wherein the friendly native Americans were also invited. It was kind of a harvest feast, the Pilgrims used to have in England. The recipes entail "corn" (wheat, by the Pilgrims usage of the word), Indian corn, barley, pumpkins and peas, "fowl" (specially "waterfowl"), deer, fish. And yes, of course the yummy wild turkey.However, the third year was real bad when the corns got damaged. Pilgrim Governor William Bradford ordered a day of fasting and prayer, and rain happened to follow soon. To celebrate - November 29th of that year was proclaimed a day of thanksgiving. This date is believed to be the real beginning of the present Thanksgiving Day.Though the Thanksgiving Day is presently celebrated on the fourth Thursday of every November. This date was set by President Franklin D. Roosevelt in 1939 (approved by Congress in 1941). Earlier it was the last Thursday in November as was designated by the former President Abraham Lincoln. But sometimes the last Thursday would turn out to be the fifth Thursday of the month. This falls too close to the Christmas, leaving the businesses even less than a month"s time to cope up with the two big festivals. Hence the change

做提取色素的实验时 色素带的宽窄是色素的含量还是溶解度?

这个是理解误区,先明白层析液分离色素的原理:各种色素都能溶解在层析液中,但在层析液中的溶解度不同。溶解度大的色素分子随层析液在滤纸上扩散得快,反之则慢,因而不同色素可以在滤纸上通过扩散分开,各种色素分子在滤纸上可形成不同的色素带。通俗讲就是溶解度大的先溶解,先在滤纸上扩散,自然就在上端,而溶解度小的,扩散时间晚,就在滤纸底部;滤纸上的宽度是表明含量,与溶解度没有关系;如果各种色素的量无限多,那胡萝卜素的宽度应该是最宽!

微电流美容仪原理 微电流和射频美容区别

现在最火的美容仪就是射频美容仪和微电流美容仪了,像大热的refa就是用的微电流,这种微电流因为是比较微弱的转化型电流,所以不会存在安全问题 什么是微电流美容仪 微电流(microcurrent),就是微小的电流。而微电流美容仪,就是可以把微电流传导到你的皮肤和肌肉的美容仪。(哈哈,真的是非常直白了。)微电流美容仪原理 从医学角度出发,微电流最早用于治疗肌肉萎缩,肌肉在微电流的刺激下会不自主地收缩,来增加肌肉的体积和紧张度。号称的增加胶原蛋白生成,原理是微电流可以直达真皮层,促进ATP(初中生物必考,是肌肉代谢的重要能源物质之一)增生,从而促进胶原蛋白生成。但相比射频类仪器(Tripollar和YAMAN美容仪,下回详解),微电流的即时显现效果强,但持续性相对较差。 因此!敲黑板!略微紧致线条而减少浅纹是有可能的,显著性的提升脸部紧致度去除深层皱纹是不可能的。2000软妹币不到的仪器不可能取代整形医院上万的拉皮手术。微电流和射频美容区别 1.射频作用于真皮层的胶原蛋白,通过加热来促进胶原蛋白合成,紧实肌肤。 2.微电流作用在皮下组织的肌肉,通过微电流模拟细胞生物电,断理面部肌肉产生更多ATP,ATP是胶原蛋白合成所需要的能量。从而使胶原蛋白增加,收紧肌肤,促进淋巴排毒。 3.起支撑作用的是骨骼→肌肉→脂肪→皮肤。 4.不能长期单方面只是促进胶原蛋白产生,要从源头做起使用禁忌人群 1、因治疗等原因体内装有金属的相应部位 2、心脏疾病患者(特别是装有心脏起搏器者) 3、因激素或疾病原因引起的毛细血管扩充者 4、因正在过敏或其他原因导致的肌肤炎症、瘙痒、红肿等部位 5、面部做过微整,植有假体、隆鼻、注射、埋入金线等部位不建议使用仪器

无水乙醇或丙酮的作用是提取色素还是分离色素?

提取.提取的原理是:绿叶中的色素可以溶解在无水乙醇中.无水乙醇也可以用丙酮代替 分离的原理是:色素在层析液中的溶解度不同,溶解度高的在滤纸上扩散得快,反之则慢.
