查询词典 free-standing system

The invasion of drilling fluid is the main cause to the damage of fractured formation. The composite salt free-gel drilling fluid is got after analyzing the influence of different kinds of such soluble adulterant as organic salt and non organic salt on the performance of the solid-free drilling fluid and studying the condition to develop the free gel structure and the method to improve the fluid's high temperature stability and inhibitive property.

Based on two algebra Riccati equation method especially the structure of the system Hamilton matrix and system observability theory, the role of invariant zeros in constructing system reduced order controllers was given. That is, by the suitable selection of free parameters of the system H(subscript ∞) controller, some points which were symmetry with the unstable invariant zeros about the imaginary axis became the stable poles of the system controller which were not observable and could be reduced from the system, thus could get further reduced order controller.

基于2代数黎卡提方程方法，特别是系统Hamilton矩阵的结构特点和系统可观测性理论，论述了不变零点在构造系统降阶控制器中所起的作用，即通过选择控制器的自由参量，使某些不稳定的不变零点关于虚轴对称的点构成系统控制器不可观的稳定极点，从而实现了控制器进一步降阶。

Adopt poaching and alcohol sinking to get coarse polysaccharide, then take MCP, MCP-1 and MCP-2 for studing in antioxidation activities. They have strong ability for scavenging free radical only in DPPH system and oxidation system of linolic acid induced by alkane radical, but negatively in hydroxyl system and in super-oxygen anions system. And MCP-2 is better than MCP-1, so we choose enzymolysis method to remove protein.
