炉正常生产必不可少的措施， 单冲量控制系统 汽包水位控制手段是控制给水，基于这一原理，可构成如图 31 所示的单冲量控制系统。 L T L C蒸 汽给 水省 煤 器汽 包 图 31 汽包单冲量控制系统 这里的“冲量”一词是指变量，单冲量即汽包水位。 这种控制系统 典行的简单控制系统。 当蒸汽负荷突然大幅度增加时，由 于假水位现象，中国石油大学（北京）现代远程教育毕业设计（论文） 9

s review article highlights the state of the art of medical robotics across several clinical areas. In this review, we will focus on robots that play an active role during a surgical intervention.

方程来得到，可以表示如下： 这里 [M]、 [C]、 [K]分别是质量、 阻尼和刚度矩阵， {F}是负载向量。 础上的数值模拟 曲柄的转速是 150rad/s (1432rpm),该灵活曲柄滑块机构的各项数值表示如下： R2=(m)， R3=(m), =(kg/m), EI=(Nm2), mB=(kg)。 这里 R2 和 R3 分别是曲柄和耦合器的长度， mB 是滑块的质量。
