Up to now, the performance index is almost described as an algebraic function of manipulating variables, it implies the response of performance index to the manipulating variables is instantaneous or the system is in steady state, and the effects of disturbances on the objective function are not taken into consideration.
在以往的工作中,大都把过程的调优变量与目标函数之间的关系用代数方程描述,这意味着目标函数对调优变量的响应是瞬时的,或假定过程处于静态,而且一般也不考虑过程中其它干扰对目标函数的影响,即在算法结构中,调优变量与目标函数构成唯一的因果关系。

The design method is described, and the calculation results are presented under the standard air conditioning condition. The working process of the two-stage expander is discussed, and the difference between the two-stage expander and the conventional one is stated. In addition, the influence of the dip angle on the expansion chamber volume is analyzed. The results show that the dip angle has little effect on the expansion chamber volume and it is suggested that the effect may be neglected in the expander design.
