The results show that the increasing Marangoni number will lead to more nonlinear distribution of temperature field, but streamfunction of the cell center; vorticity on the wall and peak value of velocity diminish first, then increase, finally lose stability. The thermocapillary convection in the whole liquid zone appears to get stronger along with the augmentation of Prantal number. The effect of increasing of Biot number on temperature and flow fields is not obvious although the convection is strengthened a little. As increasing the aspect ratio A, thermocapillary convection induced by temperature gradient and liquid viscosity becomes stronger.
结果表明:温度场的非线性分布随着Ma数的增大而加剧,但对流涡胞中心流函数、壁面涡量和轴向、径向速度峰值并不象温度场随着Ma数的增大而单调增大,而是先减小,然后增大,最后失稳,表明Ma数对热毛细对流的影响比较复杂,针对不同的物理模型,会导致完全不同的流态;Pr数愈大,流体的热扩散能力在粘性扩散与热扩散能力之比中愈占支配地位,当Ma数一定时,热毛细对流随Pr数的增大在整个液体区域内有增强的趋势;Bi数增大,热毛细对流有所增强,但不甚明显;A的增大使得由温度梯度和流体粘性诱导的热毛细对流随之增强。

We will demonstrate the specification of reference prior distribution on the random covariance matrix. We will consider the approximate uniform shrinkage prior and approximate Jeffreys' prior. Both are formulated based on the approximated likelihood function. Under generalized linear mixed models, we show that the posterior mode under Jeffrey's prior is asymptotically closer to the REML estimate than the mode under uniform shrinkage prior does.
在广义线性混合模式下,我们证明了在样本数很大时,随机效应之变异数成份的后验众数和REML估计值会近似相等,同时也建立了后验众数和REML估计值的近似关系式,并提出了比较二种后验众数与REML估计值之间远近的准则。

By systematically analyzing the single particle level and the occupation probability near the Fermi surface,and the rule of nuclear particle number deviations with proton numbers for N =8,20,28,50,82,126 neutron chains within the relativistic mean-field model with BCS theory,we have discussed the stability of the shell structure for the traditional neutron magic in the whole range of nuclear spectrum from neutron line to proton line,and predicted that traditional neutron magic number effect shall possibly disappear only in light neutron-rich nuclei.
在考虑了BCS理论的相对论平均场模型框架内,通过系统研究 N =8,20,28,50,82和126六条同中子素链中每个元素费米面附近的单粒子能级间隔、粒子数占有概率比以及原子核体系的粒子数偏离随质子数的变化规律,讨论了传统中子幻数的壳结构在从中子滴线区到质子滴线区整个核谱上的稳定性,预言只有在轻核的丰中子区域,传统的中子幻数效应才可能消失,并把计算结果和最近的文献报道作了比较。

In above mentioned conditions, the number of vessel ramification and ratio of vessel area/CAM area in VEGF group were 128.4±10.02 and 7.44±1.36 respectively, so there was no difference between PMP and VEGF groups. It is concluded that PMPs show promotive effect on the formation of capillaries in chick chorioallantoic membranes.Key words platelet??

In the paper only the range of normal value and the description of frequency distribution are discussed. In theory the widely-used percentile method to determine the range of normal value is imperfected. Curve fitting method show some advantage in determining the range of normal value, but is difficult to calculate.
从理论上说明了现在常用的确定正常值范围的方法存在一定的问题,尤其证明了大家使用得比较多的百分位数法存在的缺陷,说明了曲线拟合法的优点,而在频数分布拟合完成之后,就已经找到了频数分布资料的理论分布曲线,有了理论分布函数,我们利用分布函数计算正常值范围就比较容易,也比较准确。
