查询词典 null adjustment

A real-time interferometric method for testing asphere was proposed to measure aspherical surface with small asphericity without other null optics.

对非球面度较小的非球面，直接利用标准球面镜作为参考表面，通过数字干涉仪可以测得全孔径位相分布，将所得的数据剔除参考球面波相对理论非球面的偏差，并运用最小二乘拟合求得机构定位误差，消去此误差，即可获得真实的面形信息。

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。
