The flow performance characteristics of two check valves, the holistic opening valve and the cantilever valve, were investigated. The prototype of piezoelectric pump with double series-wound chambers was manufactured in two form valves.

设计了两种形式的被动截止薄膜阀－整体开启阀与悬臂梁阀，对两种形式阀的过流特性进行了理论分析，并应用两种形式的阀体制成了双腔串联压电泵的样机。

Globe valves are characterized by a partition separating the two halves of the body with a center passage that is opened and closed by a screw-down/screw-up seat mounted at right angle to the body.

截止阀的特点在于阀体由部分分开的两部分组成，中心流道的开启和关闭是通过安装在阀体上某个适当角度的螺杆上升或下降来实现。

The present invention relates to a kind of tunable plasma resonant cavity for PCVD optical fiber perform rod processing machine. The tunable plasma resonant cavity includes cylindrical resonant cavity casing and cut-off waveguides set on two ends of the casing, and features the tuning piston, which is set on one end of the cylindrical resonant cavity and has middle part with through hole and back end stretched beyond the casing.

本发明涉及一种用于PCVD光纤预制棒加工机床的可调谐等离子体谐振腔，包括有圆柱型谐振腔壳体，在圆柱型谐振腔壳体的两端设置截止波导，其不同之处在于在圆柱型谐振腔腔体的一端安设调谐活塞，调谐活塞的中部开设通孔，后端延伸至圆柱型谐振腔壳体外端。

The main purpose of this thesis is to research and develop three different kinds of battery chargers of resonant-switch converters. Starting with the zero voltage switch and the zero current switch converters, which employ the quasi-resonant converter technique, we gain the best parameters of the resonance components from the characteristic curve diagrams of these two converters. Then we design battery chargers based on these two structures and use them to experiment on lead-acid batteries.

中文摘要本论文之主要目的在於研制三种不同的共振开关式转换器蓄电池充电器，先探讨半共振式技术的零电压以及零电流转换器，利用这两种转换器的特性曲线图设计出共振元件最佳的参数值，以这两种架构作为蓄电池充电器，来对铅酸蓄电池做充电测试，经实验测得，零电压切换半共振式降压型转换器之充电器的开关在零电压的时候导通和截止。
