A 服从高斯分布G(2.2,0.25);B 服从高斯分布G(1.5,0.14).
定义
Y = 6A-7B,
则Y服从高斯分布G(2.7, 0.71568).
所以
P(Y > -2.7) = P (Y/0.71568 > -3.77) = 0.999918.

英语翻译
3.2.Thermal properties
The DTA results are given in Figs.1–5.Table 5 summarises the temperatures measured by DTA and heating microscopy.From these values,only one exothermic peak relating to the formation of crystalline phases is observed,exception made for frits B and D.In frit B there are two crystallization peaks (see Fig.2) whereas in frit D there is no peak (Fig.4).Additionally,frit D is the only frit presenting a ball temperature (B).
From the analysis of the results given above it is possible to establish a relationship between the sintering behaviour and the crystallization process,for each frit.Indeed,considering Table 5,one can see that the glass transition temperature (Tg) always occurs before the sintering temperature (S) while the softening temperature (M) always happens after the crystallization event.To better visualize this correlation,we plotted the characteristic temperatures given in Table 5 on the graphic of sample height versus firing temperature.Figs.6–8 show some examples of this representation for frits A–C.
From these figures it is also evident that sinterization finishes when the crystallization process occurs.That is,during crystallization the characteristic sample shrinkage,due to the sintering process stops.On the other hand,softening occurs only once the crystallization process is finished.Therefore,these results prove that crystal formation interferes with the sintering process of a crystalline frit.For frit D it was not possible to establish this type of correlation.In fact,it was explained before that this frit did not exhibit an exothermic reaction,probably because there was no devitrification of a crystalline phase.That is the reason why,for frit D,the softening temperature and the other temperatures measured by heating microscopy occurred earlier,the sintering behaviour showing the existence of a ball temperature.

热性能
DTA 结果由数据1-5给出,图表5总结由DTA和加热显微镜所测温度.从这些价值中,我们只能看出一个与结晶阶段形式相关的放热峰值,因为为弗里茨B和D做出了例外.在弗里茨B中有两个结晶峰
值而D中一个也没有.另外,弗里茨D是唯一有球形温度的弗里茨.
从以上的分析结果中我们是不可能为每一个弗里茨建立烧结行为和结晶过程关系的.的确,对于Table5,我们能够看出玻璃的过渡温度经常发生在烧结温度之前,而软化温度经常发生在结晶事件之后.为了更好的想象这种对比,我们采集了由表格五中样本高像素燃烧温度的图像提供特征温度.数据6-8为弗里茨A-C举出了些这次讲演的例子.
从这些数据中很明显得出:结晶过程发生时烧结过程结束.这也就是说,结晶同时特征样本为终止烧结进程而收缩了.另一方面,仅当结晶过程结束时软化过程才开始发生.所以这些结果证明晶体结构干扰结晶弗里茨的烧结过程.对于弗里茨D不可能建立这种对比.事实上以前已经解释过这种弗里茨是没有显示放热反应的,可能是因为结晶阶段没有的晶的.这就是对于弗里茨D,为什么被加热显微镜测出的软化的温度和其他温度发生的要早些,烧结行为显示的是球形温度的原因

你这个问题我遇到过,是不是开AE弹出Effects warning:Error parsing properties list的提示,点确定就退出了启动界面,重装还是一样.
下面我大体上说说解决方法:
删除After Effects的配置文件!
路径:C:Documents and Settings[user]Application DataAdobe
有的电脑看不到Application Data这个文件夹,是因为没有选中[显示隐藏的文件和文件夹],在控制面板〉文件夹选项〉查看〉取消受保护操作系统文件 选中显示隐藏的文件和文件夹
在Vista系统里可能打不开Application Data这个文件夹,解决方法是:用Vista优化大师〉系统管理〉右键菜单〉添加右键菜单〉管理员取得所有权限,然后在文件夹上点右键>管理员取得所有权限,然后就可以打开Application Data文件夹了.
进入Application Data>Adobe文件夹里找到After Effects文件夹并删除它,重起AE问题解决,如果没有解决,试着把Adobe文件夹里的全部文件删除.
好了此问题删除AE的配置文件就可以,在这里感谢我的好友RayCrown告诉我问题的解决方法.
在这里还有一个更快的方法删除AE配置文件,双击AE快截方式,然后立即快速按CTRL+SHIFT+ALT,弹出Are you sure you want to delete your preferences file?点OK删除即可.

Abstract:The properties of the passive film formed on 2205 stainless stee1 in acetic acid at high temperature that contained chloride
ions were studied by atomic absorption spectrometry(AAS),X—ray photoelectron spectroscopy(XPS),and electrochemical polarization
meas~ements.AAS results show that toolybdenum is enriched on the surface as the passive film is dissolved.This enrichment
decreases the corrosion resistance because it hinders chloride adsorption and Fe ion dissolution.and acts as a local pH buffer because
n consumes protons.The dissolution ratio ofFe/Cr is approximately 10 during the active dissolution ofthe passive film.XPS results
indk:ate that when the potential is in the passivation region,Cr comprises about 50% of the mc协1 cations in the near-surface region
of the passive fiIm and is the main metal constituent in this region.W hen the polarization potential is much greater than the transpas.

英语翻译
The relevant cost drivers for residential properties in Germany are identified by using regression analysis.These drivers are the median floor height,the share of the ancillary area for services,the construction duration,and the compactness of the building.Of the four cost drivers,the median floor height proved to have the greatest explanatory significance.The method proves to be suitable for answering the research question.However,some theoretically relevant drivers were not available for the properties being examined.Therefore,these drivers have to be followed up and examined during future studies.Detailed information should be included especially about materials,the planning and construction process,and specific data about various dimensions of the building.

英语翻译
Preparation and anti-crease properties of water-soluble silicone modified polyester auxiliaries for fabrics in dyeing process.
Abstract:a novel series of silicone-modified polyester (SMP-polyester) has been prepared by the reaction of
organopolysiloxane with hydroxyl terminated polyester.The polyesters are obtained by the polymerization of maleic anhydride (MA) and polyethylene glycols (PEGs).These SMP-polyesters are water-soluble and can be used as auxiliaries in the dyeing process because they exhibit good surface activities such as surface tension,low foaming and wetting power.The SMP-polyesters can be successfully employed as an auxiliary in dyeing polyester fabric with disperse dyes at elevated temperatures without occurrence of creases.
Introduction:
In modern textile dyeing processes,such as the rapid dyeing of polyester fabrics by jet dyeing machines,the speed of polyester fabrics movement by circulating dye liquor is faster than that in the normal dyeing method.Creasing or scarring of fabrics is often encountered in the fast moving fabric during the dyeing process.in most cases,auxiliaries and scars on fabrics by providing lubrication or softening of the fabrics during dyeing.Commercial silicone surfactants formulated into an emulsion by the addition of emulsifiers are used as lubricants or softeners of the fabrics.However,commercial silicone surfactants can not be used for anti-creasing despite their ability to soften the fabrics for anti-creases because de-emulsion will occur under dyeing conditions at elevated temperatures and because the aggregation of disperse dye particles present in the dyeing system form rapidly as a result of the hydrophobic interaction between disperse dye particles and silicone surfactants with hydrophobic character as well.In the process of dyeing polyester fabrics,this aggregation causes dyeing polyester fabrics,this aggregation causes dyed polyester fabrics to appear unleveled or specked.

Looking from the perspective of chemical properties,the high
alkali content of rice straw and rice husk can ultimately lead to
slagging and fouling problems in combustion equipment.Hence,
pre-treatment of these resources becomes an integral part of utilising
these resources as fuel.
Leaching process can remove unwanted substances in the rice
straw.It can reduce slagging,fouling as well as corrosion problems
in furnaces system and subsequently extend the operating life
of a boiler.Studies have shown that distilled water or tap water
can efficiently reduce the quantity of potassium,sodium and chlorine
in the rice straw .Researches have also demonstrated that
it is economically viable to utilise leached rice straw as a fuel in
commercial combustion power systems .

studies on the relation of ion substitution to structure and properties

上述极具吸引力的热膨胀特性也引起了不少研究者的兴趣,其中,Ba1+xZr4P6−2xSi2xO24这种低温膨胀特点的陶瓷材料因为在高温下也具备良好的机械性能与化学稳定性而吸引人.尽管离子成份与结构及性能(比如热膨胀)的相互作用已得到广泛研究,但是至今仍没有详细的方法对Ba1+xZr4P6−2xSi2xO24进行机械及化学性能的研究[11-13].目前的工作中,提出两个不同的NZP结构式来研究这一问题,分别命名为Ca1−xBaxZr4P6O24和Ba1+xZr4P6−2xSi2xO24.
