In the paper, the common expression of the non-uniform load shareing factor was deduced, and a function parameter--forc-arm factor and the concept of ideal centre position were presented and their solutions were given, which makes it possible that the dimensions and the capability of load equilibrium of the mechanism could be determined. The criteria of optimum load balancing mechanisms selection were set up with consideration of the effects of frictions and turning pair clearances.

本文通过对平面连杆式均载机构的功能指标—载荷不均匀系数的推导和分析，提出了力臂系数、理想中心位置这样一些能反映均载机构功能与运动结构关系的参数与概念，并给出其求解方法，它们还可以用来确定平面连杆式均载机构各构件的最佳长度尺寸。

在鼓泡透明玻璃反应釜里模拟渗漏系统气体穿越多孔隙砂层形成水合物的过程实验，分析了气体迁移对气体水合物形成时气液界面的传质传热性质影响，表明实验中气体迁移形成水合物的过程是一种相平衡曲线动态移动的过程；在形成水合物的气—液界面存在具有一定厚度的过渡层，只要过渡层内气体达到饱和即可形成水合物；气体在迁移中不断形成水合物并在孔隙中形成过压，导致地层骨架的力学破裂和失稳；必须建立一个新的水合物相图以适应气体迁移形成水合物过程的这种新特性。
