下降器

因此，即使钢瓶压力下降，调整器的输出压力保持恒定，从而不需要经常调整控制钮。

Thus , delivery pressure remains constant even as cylinder pressure decays , eliminating the need for frequent control knob adjustment .

试验引起滑油劣化以及产生油泥生成物，使得摩擦副表面间的油膜难以破裂，导致摩擦系数与摩擦力矩降低，摩擦力矩下降是同步器失效的根本原因。

The oil deterioration and sludge formation during the test make the oil film between the friction pair surface hard to rupture , which leads to the decrease of friction coefficient and friction torque . The friction torque decline is the fundamental reason for the failure of the synchronizer .

随着超级电容器制造工艺的提高和成本的下降，超级电容器储能及应用技术研究将是一个很有潜力的发展方向，具有很大应用价值和市场潜力。

Super capacitor is becoming a potential power storage technique with the improvement of technology and decreasing cost of production .

随着催化剂颗粒的增大，床层最高温度呈下降趋势，反应器出口二甲醚的摩尔分率、甲醇转化率以及二甲醚的日产量都减小。

The hot temperature of catalyst bed is on the decline with the increase of the catalyst particle size . The outlet mole fraction of DME , methanol conversion and the daily capacity of dimethyl ether all decreased due to the increase of the catalyst particle size .
