Used the metering - out control system in which the hydraulic cylinder was the executive element as research object in this thesis , the experimental research about the effect on the pressure p1 , p2 of the hydraulic cylinder chambers when series - connecting throttle valve or governor valve on the return oil - line under the step load changing have made 本文以单出杆液压缸为执行元件的出口节流调速系统为研究对象，在其回路上分别串接节流阀和调速阀，当负载发生阶跃变化时，对液压缸两腔压力p _ 1 、 p _ 2的影响进行了试验研究。
In the approach , non - load machine switch is replaced by scr controlled by mpu to regulate the temperature . this control precision is greatly improved , and at the same time parameters can be automatically stored and displayed during the manufacturing process , it also included some other auxiliary controlling functions , such as over - temperature alarm , work piece input or output reminding , etc . the fuzzy pid control algorithm consists of fuzzy control and digital pid adjustment 针对盐浴变压器只能进行无载分接、有级调节的问题，本方案采取在变压器原边串接晶闸管的方法，将手动转换的温度控制，即无载分接开关机械触点调节电压改为单片机自动控制晶闸管的导通，将手动控制温度改为模糊pid控制，从而提高了控制精度，降低了工人劳动强度。
The printer , protection locks or other peripherals that are serially connected behind a protection lock and will consume a computer s output powers ; therefore , if specifications of a protection lock s components all work at a 5v standard output environment , the devices or equipments that are serially connected behind the protection lock will reduce the output powers and therefore make the protection lock work properly , which causes an inconvenience to users 因为串接在保护锁后的打印机保护锁，或是其它的外围装置，都会消耗计算机的输出功率因而，如果保护锁的组成零件规格，是工作于标准的5v输出环境时，由于其它串接于后的装置或设备，将会便得输出功率下降，进而会使得保护锁无法正常的工作，造成使用上的困扰。
When the governing valve was series - connected on the return oil - line in the metering - out control system , under the same flow area and the same adjusted pressure of relief valve , with the incremental quantity of step load , the pressure highly - adjusted capacity of the hydraulic cylinder chamber with piston - rod increased , meanwhile , it ' s time of rise , time to peak and the governing time all increased . at the same time , the pressure highly - adjusted capacity of the hydraulic cylinder chamber without piston - rod increased 当出口节流调速系统的回油路上串接调速阀时，随阶跃负载的增加，在相同流量阀开度、相同溢流阀调节压力的情况下，液压缸有杆腔压力p _ 2 ( t )的超调量是增加的，上升时间、峰值时间以及调整时间也是增加的；液压缸无杆腔压力p _ 1 ( t )的超调量是增加的。
According to objective orientation , the authors offered the following suggestions : in terms of routine setup , we should base the main contents on the essential combos of representative martial arts carefully selected , and base the initial posture , ending posture and transitional posture on the exclusive chinese fist clenching courtesy ; in terms of routine training , we should seek for the power of expression , and concurrently take care of move standardization as well as offense and defense awareness ; in terms of teaching , we should adopt the mode of learning single move techniques and combo move techniques first , then doing an antagonistic exercise , and finally putting series moves into a complete routine 根据目标定位，建议在套路编排方面，以精选的代表性拳种的精华组合为主要内容，以中国独有的抱拳礼为起收势和衔接点；在套路训练方面，以求取劲力为立足点，并兼顾动作的规范和攻防意识；在教学方面，采用先进行单势技法、组合技法学习，再进行对抗性练习，最后进行套路串接的模式。
Accorded to the experimental research , under different flow area of flow valve and different adjusted pressure of relief valve , conclusion that the regulation of the pressure p1 , p2 in the two cylinder chambers varied with the change of step load were as follows : when the throttle valve was series - connected on the return oil - line in the metering - out control system , under the same flow area and the same adjusted pressure of relief valve , with the incremental quantity of step load , the pressure highly - adjusted capacity of the hydraulic cylinder chamber with piston - rod decreased , meanwhile , it ' s time of rise , time to peak and the governing time all decreased . while the pressure highly - adjusted capacity of the hydraulic cylinder chamber without piston - rod increased 通过试验研究得出系统在不同的流量阀开度、不同溢流阀调节压力(进口压力)下，液压缸两腔压力p _ 1 、 p _ 2随阶跃负载变化的规律：当出口节流调速系统的回油路上串接节流阀时，随阶跃负载的增加，在相同流量阀开度、相同溢流阀调节压力的情况下，液压缸有杆腔压力p _ 2 ( t )的超调量是减小的，上升时间、峰值时间以及调整时间也是减小的；液压缸无杆腔压力p _ 1 ( t )的超调量是增加的。
