什么样的文章需要skimming
什么样的文章需要scanning?
我发现有些文章不一定都要两者兼具的 给我指点迷津

英语翻译

this area lends itself to high levels of shrinkage through 'give-aways' if the ticket price is different to the scanning price at the cashier check out,as discussed under the shrinkage module.

sas中anyalnum函数
Anyalnum函数的应用 Scanning a String from Left to Right；
data _null_;
string='Next = Last + 1';
j=0;
do
until(j=0);
j=anyalnum(string,j+1);
if j=0 then put +3
"That's all";
else
do;
c=substr(string,j,1);
put +3
j= c=;
end;
end;
run;
The following lines are written to the SAS log:
j=1 c=N j=2 c=e j=3 c=x j=4 c=t j=8 c=L j=9 c=a j=10 c=s j=11 c=t j=15 c=1 That's all.
这个程序有点看不明白,为什么j后来会等0呢?

请问阅读课中scanning和skimming的意义?
我知道scan是细看和审视,scan through是粗略地看,浏览
但有个例句：i scanned the page quickly for her name.的翻译是我迅速浏览那一页她的名字.也没有用到through,为什么要用迅速浏览,而不是仔细看呢.
还有,skim也有浏览的意思,它和scan到底有什么区分呢?

2.9.Scanning electron microscope (SEM)
The C.albicans KCTC7122 was resuspended in PBS,to a final concentration
of 108 cells/ml.200 ll aliquots of C.albicans suspension
were incubated with 22 ll of 250 lg/ml di-K19Hc.For a control,the
same amount of C.albicans suspension was mixed with 22 ll of
0.01% acetic acid and incubated for 5 min at 30 2C.The di-K19Hctreated
or untreated C.albicans samples were then fixed in 0.05 M sodium
cacodylate buffer (2% glutaraldehyde,2% paraformaldehyde,pH
7.2) for 4 h.After fixation,the samples were centrifuged at 2000 rpm
and rinsed three times for 20 min each with sodium cacodylate buffer.
The samples were then dehydrated through a graded ethanol series
(50%,70%,90%,95%,100% ·2),for 30 in each.The samples were
freeze-dried for 8 h,and coated with a light coat of gold palladium.
The specimens were then viewed with an S-2400 scanning electron
microscope (Hitachi,Japan).
3.Results
3.1.Peptides
The primary amino acid sequences of the synthetic halocidin
congeners used in this study,di-K19Hc and K19Hc,are shown
in Table 1.Table 1 also provides the sequences of P18 and
buforin II,used as the standard peptides in this study.

英语翻译
Scanning is a search for information which is of some special interest.A student has first to know the arrangement for information before he can start his search efficiently.Much of the reference material is arranged alphabetically .A dictionary,an encyclopedia,an index of a book,or telephone directory is usually arranged alphabetically for easy quick location of information.But not all material is arranged this way.TV programs,for example,are listed by day and time.Historical data and tables may be listed by month and year.And the sports pages of the newspaper are arranged by category:baseball,football,tennis,and so on.
Whatever the source of reference,it is arranged in some logical way.To prepare for scanning therefore,you should take a minute or two to discover the organization of the material.As soon as you are familiar with the arrangement of information,you can proceed immediately to find the part most likely to contain the information desired.

Scanning is reading a text quickly______
A.to get the general idea.
B.to get the implied information
C.to identy writer's attitude
D.to find specific information

Scanning electron microscopy (SEM)
(JEOL JSM-5800LV model) was performed on the samples.Specific
surface area (SSA) of the samples was also analyzed by Autosorb-1
analyzer using BET method.Cation exchange capacity (CEC) of the
samples was measured according to Schollenberger,using
neutral NH4OAC and 10% NaCl as saturating and replacing solu-
tions,respectively.

2.3.Scanning electron microscopy (SEM)
Nanoparticles in solution were dropped onto a silica surface precoated with a thin layer of gold and palladium.The nanoparticles were lyophilized using a JFD-310 (JEOL,Japan) prior to analysis,and micrographs were obtained using a SEM (JSM-6360,Japan).

Skimming and scanning
If you do not need to read every word,skimming and scanning may be enough to give you a general idea of what the text is about.
When you read,you may understand the text better if you skim and scan the passage first．This way,you can get a general idea of the text．You will then be able to read more quickly and remember more information when you read it the second time．这段话怎么翻译?
如果你不需要阅读每一个单词，略读与浏览就可以帮你找出文章的中心思想。
当你阅读的时候，如果你先将文章浏览一遍就可以更好地理解这篇文章。用这种方法，你可以找出一篇文章的中心思想。然后你就会读得更快，当你第二遍读这篇文章时就会记住更多的信息。
以上是我自己翻译的,

英语翻译
Post-scanning data processing is an important step for any successful application of these scanning systems.The object of post-scanning data processing is to reconstruct surface models from 3D point clouds.Strategies for surface reconstruction have proceeded in two main directions:reconstruction from unorganized points and reconstruction that exploits the underlying structure of the acquired data.The latter is called surface reconstruction using structured data.These two strategies can be further divided according to whether they operate by reconstructing parametric surfaces or by reconstructing implicit surfaces.The algorithm employed here falls into structured data reconstruction using implicit function methods that use samples of a continuous function to combine structured data.Previous relevant work mainly applys to laser scanning technologies.
