Consistent with predominantly stochastic gene expression and increased energy demands induced by aneuploidy,the "buffering" canalization processes in Down syndrome would be reduced thereby giving rise to increased variance to less stable developmental pathways such as proliferation.

与非整倍体诱导的主要预测基因的表达和增长的能量需要相一致，Down综合征中的"缓冲"的发育稳态过程将会减少，从而导致像增殖这样不稳定的发育途径的多样性增加。

Using a decomposition in canonical form, a multi-sensor distributed optimal fusion reduced-order filter for each state component is proposed based on the component fusion algorithm weighted by scalars in the linear minimum variance sense for descriptor discrete stochastic linear systems with multiple sensors. It requires in parallel the calculating of a series of scalar weights.

结果表明：不同品种楸树幼树的高生长、直径生长、叶片长宽比、单株叶片数和净光合速率等生长和生理指标存在显著差异。

Only in cauchy distribution are expected value and variance non-exist. By sas programming with SQL and MACRO we solve the fit of frequency distributions of data with these distributions. Meanwhile good-of-fit test is actualized so that the bound of parameters of distribution function is dwindling until the desired accuracy is arrived. The process is executed by the circle of macro.

利用SAS的SQL和MACRO等语句编写了大量的程序，以拟合优度检验结果为标准，不断地变换八种分布的参数变化范围，通过宏程序的不断循环，逐步缩小参数的范围，最后达到预先设定的标准，从而可以发现八种分布中哪几种分布能比较好地拟合给定的实际频数资料，我们再根据拟合优度检验的结果判断出哪种分布拟合实际频数资料最好，最终获得该频数资料的最佳的理论分布函数形式。
