金属螯合四肽与其单克隆抗体可变区相互作用的三维结构的计算机模拟

The DNA sequences of positive product shows that: there are two point mutation ( T → C) in the sequences of ⅴ~ⅶ variable regions of throat swab of one pediatric patient, other sequences are same as those Mg type strain ( G 37 T).

阳性产物DNA测序显示，除1例上感儿童咽拭子的第Ⅴ～Ⅶ可变区序列存在二个T→C点突变外，其余与Mg标准株（G37T）序列相同。

The thermal adaptation of the ant acclimated respectively to constant temperature and to variable temperature was studied to understand the effects of the two thermal acclimation method on preferred temperature, critical temperature and locomotor performance, and to test the optimality models;

通过对恒温、变温驯化下鼎突多刺蚁热适应性的研究，探讨不同的温度驯化方式对鼎突多刺蚁热偏爱性、温度耐受性及运动能力的影响，并验证最适性模型；

These two equations show that the time rate of change of information entropy density originates together from the drift, diffusion and production in coodinate space and state variable space;

这两个方程表明：信息熵密度随时间的变化率是由其在坐标空间和态变量空间的漂移、扩散和产生三者引起的；

Based on the asymptotics of the test statistics, we further propose two easy ways to implement variable selection.

另外基于统计量的渐近性质，我们提出了两种非常简单的不基于模型假设的变量选择方法。
