The main reasons for the higher efficiency are the elimination of the water pump, the elimination of the water heat exchanger (which is a source of heat losses), and the phase change of the refrigerant in the ground itself, allowing a higher temperature gradient between loop and ground resulting in a higher rate of heat transfer.

为高效率的主要原因是水的泵，水的热交换（这是一个消除热损失的来源），以及本身在地面制冷剂相变，从而使一回路和地面之间的热传递率较高导致较高的温度梯度。

One points at a sequence of one sparse linear algebra system of equation ,utilizing frequent treatment sparse matrix data structure at present that is according to the competent store structure, design the law of conjugation gradient method which solves the equation group of the sparse linear algebra of asking analyses the complexity of calculating.

第一部分针对一类稀疏线性代数方程组，利用目前国际上使用比较频繁的处理稀疏矩阵的按行稀疏存储结构，设计了求解稀疏线性代数方程组的共轭梯度法，并分析计算复杂度。

In order to avoid the repetition, we find a group of coefficients that are generated with field and its gradient data. To establish explicit linear relation between structural index based on the linear relation, depth is calculated when calculated parameters are given without touching the field data. Accordingly, it can avoid the repetition of Euler's equation calculation and greatly reduce the works load as well as enhance efficiency.

The results showed that 1 transport of Gly-Pro was slightly quicker when Na+ replaced by K+ during the first period of 20 min;2 Na+ concentration gradient stimulated 4.6-fold of L-alanine transport, but had no effect on transport of Gly-Pro. Harmaline reduced transoport of L-alanine significantly but had no effect on Gly-Pro transport.

结果表明：(1)用K+替代Na+，并没有降低Gly-Pro在BBMV中的转运量，在孵育前20 min时间内，Gly-Pro的转运量稍稍提高；(2)Na+可使BBMV对L-丙氨酸的转运量提高到4.6倍，但不影响Gly-Pro的转运；二氢骆驼蓬碱显著地降低L-丙氨酸的转运，但对Gly-Pro的转运无影响。
