速度调节

The force on the jet pipe in the hole jetted is analyzed, and it is indicated that the resistance on the jet pipe is the main factor influencing the feeding of jet pipe.

分析了喷管在喷孔内的受力，指出喷管在喷孔内所受的阻力是影响喷管送进的主要因素，据此调节喷管送进控制液缸控制腔的压力可控制送进速度和限制最大推力。

Traditional plastic injection molding machine relies on constant rate pump in oil supply, and each action in the process of plastic injection may have different requirements on speed and pressure. The surplus oil flows back to the oil tank through the proportioning valve in the way of flooding adjustment. In the whole process, the rotation speed of motor remains unchanged, so the oil volume is fixed as well. Furthermore, the action is intermittent, and not of full load, so a great amount of oil is wasted.

传统的注塑机是采用定量泵供油的，注塑过程的各个动作对速度、压力的要求也不一样，它是通过注塑机的比例阀采用溢流调节的方式将多余的油旁路流回油箱，在整个过程中，电机的转速是不变的，故供油量也是固定的，而由于执行动作是间隙性的，也并不可能是满负载的，因此定量供油就有很大的浪费空间。

During auto-synchronising of unit, the turbine speed has to be adjusted and to be steady before changing the synchronising switch into automatic state.

机组自动并网时在将并网开关打到自动以前，必须对汽机速度进行调节，使其稳定。

After puncture is successful, enjoin patient loose fist secures syringe needle with adhesive plaster, adjust infusion speed.

穿刺成功后，嘱患者松拳用胶布固定针头，调节输液速度。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
