states the characteristics of the condensing-temperature control in variable condenser water flow of central air-conditioning systems. analyses the effects of variable condenser water flow on cop of centrifugal chillers. indicates that although the negative effect is not negligible, it is less than the positive effect on pump's energy-saving and the condensing-temperature control is helpful to the resulting energy-saving for air-conditioning systems by combining with an example.

摘 要：论述了在集中空调冷却水变流量系统中冷凝温度控制法的特点；分析了冷却水变流量对离心式制冷机性能系数的影响；结合实例说明虽然冷却水变流量对于冷水机组制冷性能的负面影响不可忽略，但这一负面影响较对于水泵节能的正面影响要小，采用冷凝温度控制法对于空调系统综合节能是有益的。

如果变长不严轻，可不合调不小晒版机的真空度，仍能吸陡；但如变长很严轻而感化呼气时，可用电呼风不合陡均呼一下，硫酸纸关上，不即能吸陡了，的确不动，不即只好轻新输不入、拆版。

In the design procedure, we do not need to know the specific values of the system parameters . We only require that the member functions of the input variable are triangular-shaped and the central values of the output variable member functions are selected in order to satisfy the stability expressions.

在模糊控制器的设计过程中，不需要知道对象的系统参数（A，b，c或A，B，C）的具体值，而只要求输入变量的隶属函数为三角形和输出变量的隶属函数中心值的取值满足稳定性条件所要求的关系式。

The cephalometric radiography and ultrasound image of swallowing were recorded just before and after anterior teeth retraction. All the changes and correlation between the variable of anterior teeth and the variable of tongue movement during swallowing were all discussed. The result showed that there was no significant change on duration and magnitude during swallowing after anterior retraction.

以13位符合条件的志愿者为受测对象，分别在前牙退后之前后各取一次测颅X光片及超音波吞咽之影像资料；而后以测颅X光片描绘取得前牙距离、角度的改变比率，另以电脑辅助分析超音波吞咽影像，得到舌头吞咽各分期的时间振幅之改变比率，再进行统计分析。
