约束

The result of simulation shows:(1) Different goals of production decision making have different influences on grassland degradation. The production decisions aiming at income maximization is more favorable for relieving grassland pressure that the ones aiming at scale maximization.(2) The effect of herdsman's self-restriction on inhibiting grassland degradation is not less then government mandatory regulation for the grassland utilization;(3) Under the situation of overgrazing, The price rise of livestock products will be helpful to decrease the breeding scale;(4) The application of production technology in risk reduction will be helpful to decrease the breeding scale.

对模拟结果的分析表明：(1)以收入最大化为目标的生产决策比以规模最大化为目标的生产决策更有利于缓解草场压力；(2)牧民的自我约束对抑制草地退化的效果不小于来自政府强制性约束的效果；(3)在目前超载过牧的情况下，价格上涨有助于降低饲养规模；(4)降低生产风险的生产技术进步有助于减少饲养规模。

Secondly,based on rigid-body kinematics,the model of degree of freedom was formulated to describe the relationship between the machining requirement and the theoretical constraint degree of freedom .

工件自由度的合理约束是夹具设计的关键，基于定位原理的数学模型，根据齐次线性方程组解结构的性质，首先推导了三个定位方案的合理性判据；然后，基于刚体运动学，建立了描述加工要求和理论约束自由度之间关系的自由度模型；最后，利用典型实例详细讨论了自由度模型及合理性判据的分析应用过程。
