In this work, the performance of six-needle steel electrodes and four-needle graphite electrodes in detecting bio-impedance was compared. Also, coefficients of variability were applied to assess the stability of the system. Experiment showed that the coefficient of variation of the system was less than 6% if the frequency was above 1 kHz. Intra class correlation procedures were applied to assess the reliability of the system due to temperature variability. Values of Ri, Re, C in the system model were reliable with intra class correlations of more than 65%.

探讨了检测电极设计方案，比较分析了六钢针电极和四针石墨电极的性能，同时通过试验证明了系统的稳定性，1 kHz以上系统的变异系数CV＜6%；以组内相关系数ICC来评定在不同温度下系统的可靠性，系统模型中Ri、Re、C的ICC均大于65%，系统稳定可靠。

The senior class students in primary school are a special group who is on the tuning from jejuneness to mature and have their own typical character of this age. On the understanding of the typical character of them is the basic step of efficient class management and educational work.

小学高年级是一个特殊的群体，他们身心正经历着由幼稚转向成熟的巨变，具有这个年龄阶段特有的性格特征，把握好这个阶段学生的特点，实行行之有效的班级管理，是做好教育教学工作的重要基础。

It is proved that the two-dimensional non-hydrostatic Boussinesq equations on the x ? z plane with the kinetic viscous term and the thermal dissipative term are unstable equations in the C 2 function class.2. If we replace the influence of the kinetic viscous term by Rayleigh friction and the thermal dissipative term by Newton cooling, the new generalized equations are stable equations in the C 1 function class. The construction of the solution space and the discriminating method for well-posedness of the problem of determining solution are given.

本文的主要结果如下：1证明了在y方向上均匀的带有运动粘性项以及热耗散项的两维非静力、Boussinesq近似的x-z面上两维旋转流体的控制方程组在C 2函数类中是一个不稳定的方程组。2如果以瑞利摩擦来代替粘性的影响，以牛顿冷却来代替热量的耗散，则所获得的一个新的方程组在C 1函数类中是一个稳定的方程组，给出了其解空间的构造和各种定解问题的适定性的判别方法。
