But after bile salt stimulation, total bile acid and glutathione concentration in bile were significantly increased in AQP8 null mice compared with wild type mice.

本课题利用AQP8和AQP1基因敲除小鼠模型，系统地研究了水通道蛋白AQP8和AQP1在小鼠"原始"胆汁的形成和胆囊内胆汁浓缩过程中的作用。

After comparing the two type of tests,we came to some conclusions.The tests based on binomial test can be regarded as some kind of permutation tests under certain definition of "permutaton".If the tests are related to statistics,then whether they can be viewed as permutation tests depends on if the value of the probability,p,is known where p is the population parameter in the null hypothesis.For tests like Kolmogorov goodness-of-fit test,since the statistics is calculated based on empirical distribution function,hence no matter how we repermutate the observations,the order statistics is the same.This kind of tests can't be regarded as permutation tests.

我们得到的结论为：在一般的无母数检定中，如果检定与binomial test相关，基本上都可以视作排列检定的一种；与卡方检定相关的检定，基本上和p值已知或是未知有关，这个p值为原始假设下所要检定的母体机率值；其他检定如Kolmogorov goodness-of-fit test，由於统计量的值是根据empirical distribution function决定，而不论如何重新排列样本，其顺序统计量都不变，所以无法视为一种排列检定。

The reference domain is assumed to be a bounded open set of R~N with boundary Γ of class C~2. We investigate in this paper the null controllability for the semilinear parabolic equations in non-cylindrical domains. The fixed point method is used in the proof.

本文讨论了定义在上述非柱形区域中的半线性抛物方程零能控性，我们使用的方法主要是通过同胚映射将非柱形区域中的抛物方程转化为柱形区域中的抛物方程，再利用不动点方法得到半线性抛物方程的有关结果。
