Mono-calcium phosphate, sulfuric acid and urea were used for simulating the crystallization of calcium sulfate in the reaction of phosphate rock and urea-sulfuric acid.

结果表明，与无尿素的结晶过程相比，尿素使出现结晶的时间延长了150%，但悬浮液密度增加50%，结晶在长度和宽度上均有所增加，特别是宽度上的增长超过50%。

University of Chicago, where he remained officially for exactly a generation and where his students in advanced composition found him terrifyingly frigid in the classroom but sympathetic and understanding in their personal conferences.

他在那里正式任职长达整整一代人的时间。他的高级作文课上的学生觉得他在课上古板得可怕，但私下交流却富有同情和理解。

It also gives the definitions and stochastic properties of pure random process, random walk process and AR(1) autoregressive process, and analyses the simulative data of three typical random processes using wavelet analysis, frequency spectrum analysis and time-correlation analysis. The stochastic properties of time series and the trend component, the time length of time-correlation and the properties of main frequency of these three typical random processes are summarized as the templates for further research.

给出了包括纯随机过程、随机游走过程和 AR(1)自回归过程等在内的基本随机过程的定义和统计特征，并运用小波分析，时间相关和频谱分析对这三种基本随机过程的模拟数据进行分析，归纳出它们在时序上的随机特征、低频信号趋势项特征、时间相关的长短以及主频信号的位置等特点，作为研究 GPS 接收机误差和多路径效应的随机特征的模板。

SEO is a long term effort and should be viewed as an ongoing investment in time and resources.

搜索引擎优化是一个长期的努力并且应该被看作一个进行中的时间上和资源上的投资。

Lastly, the ruin probability of the bidimensional perturbed risk model are studied, whose upper bound of Lundberg-type within infinit-time is obtained and discussed for the case of light-tailed using the martingale technique, the conclusion is gotten that the strength of the dependent of B strongly impact the upper bound can be achieved.

第四章主要研究了带有扰动项的二维风险模型的破产概率，应用鞅论的技巧，在轻尾条件下，求出Lundberg-type在无限时间内的破产概率的上界；并对破产概率的上界进行讨论，获得的相关性的强弱影响着破产概率可达到的上界。

You have got yourself a bimbo – and one who is much too young for you.

对于一位律师而言，你有非常好的直觉，并认为把个人时间浪费在严格意义上的个人活动上确实是件愚蠢的事情。

We set up an orthogonal experiment, use diclofenac sodium as drug model, detect the pemeate velocity, lag time, and transit dose accumulated in 24 hours(Q24) as index of drug action of azone, menthol and camphol using together on skin of back of unde rat on the equipment of percutaneous absorption in vitro, evaluate the contribution of transdermal enhancers by Topsis.

在离体透皮吸收装置上，采用正交试验的设计方法研究不同浓度的氮酮、薄荷醇、冰片联用对双氯芬酸钠在离体裸小鼠背部皮肤上的透皮行为，以累积透过量、渗透速率和滞后时间为药效指标，运用Topsis法评价促透效果。

It might be a better way to view the multivariate analysis as one in a multi-dimensions vector space because characteristic roots and characteristic vectors are related in that way.

因为各方面的原因，包括时间上及数学基出方面的原因，现在不太可能从头到尾细致地学一遍空间解释几何及矩阵代数，以及关注太多的多元统计上的细节，我只求会用。
