The Development and Application of Combined Thermoregulatory Mathematical Models

Thermoregulatory mathematical models have being developed for more than half a century and obtained more and more wide application. Among them, the "engineering-physiological" thermal models, which correlated closely to the man-machine-environment system, are the ones that developed most rapidly and have been widely accepted by thermal physiologists and environmental control engineers.This paper attempts to outline briefly the development and application of such kind of thermal models, discusses how to further develop and apply various combined thermal models in practice, and puts forward four respects of suggestions for establishment and modification of combined thermal models of man-clothing-cabin environment.     

一维抛物型偏微分方程 Padé 逼近的并行算法

一维抛物型偏微分方程可以用精细积分方法精确求解．当精细积分中的矩阵指数函数用它的Ｐａｄé逼近格式来代替时,可以得到一系列由简到繁,精度由低到高的差分格式,因而便于根据实际计算的需要进行选取．Ｐａｄé逼近格式的求解主要包括矩阵运算和线性方程组的求解．利用Ｐａｄé逼近格式对应的方程组系数矩阵为带状矩阵的特点,把原来在整个区域上求解的问题转化为分区域求解,从而实现了Ｐａｄé逼近的并行算法．算例的结果表明该方法具有较高的并行性和计算效率     

铁纳米线阵列的结构与微观磁性

采用电化学方法制备了平行排列的Fe纳米线阵列。利用透射电镜、X—射线衍射、物性测量系统和穆斯堡尔谱分别对样品的形貌、晶体结构、宏观磁性和微观磁性进行了研究。结果表明样品形状均匀，但沿纳米线方向有晶体织构，且存在着很强的形状各向异性。利用结果，结合计算机模拟，对样品中原子磁矩的分布进行了讨论。

Switched Capacitor Network Analysis by Means of TCM

The totally coded method (TCM) reveals the same objective law, which governs the gain calculating for signal flow graph as Mason formula does. This algorithm is carried out merely in the domain of code operation. Based on pure code algorithm, it is more efficient because figure searching is no longer necessary. The code-series (CS), which are organized from node association table, have the holoinformation nature, so that both the content and the sign of each gain-term can be determined via the coded method. The principle of this method is obvious and it is suited for computer programming. The capability of the computeraided analysis for Switched Capacitor (SCN) can be enhanced.
