The converter can be improved just by exchanging the position of the resonant inductance and the transformer such that the transformer is connected with the lagging leg. The improved converter has several advantages over its counterpart, e.g., the clamping diodes conduct only once in a switching period, and the resonant inductance current is smaller in zero state, leading to a higher efficiency and reduced duty cycle loss. The operation principle of the improved converter and the comparison with the original converter are analyzed in this paper. The effect of the blocking capacitor in series with the transformer or resonant inductance is discussed, and a best scheme is determined.The improved converter is adopted to design the DC/DC converter of secondary power supply in HVDC power system.

本文将谐振电感和变压器交换位置，使变压器与滞后桥臂相连，这样箝位二极管在一个开关周期中只导通一次，同时零状态时谐振电感电流较小，有利于提高变换效率和减小占空比丢失，本文分析改进后变换器的工作原理，并与改进前的变换器进行对比，讨论隔直电容在不同位置对变换器工作的影响，确定一种最佳工程方案。

Rotating disks are the basic mechanical element of steam and gas turbines, grinding wheels, circular saws, and computer disk memories.

旋转圆盘是工业中应用广泛的一种基本机械元件，它广泛的应用于旋转机械，诸如涡轮机、圆锯、计算机硬盘等，上述系统中这些盘类结构严重的横向振动将使机器工作时的精度降低﹑动态性能下降以及造成被加工材料的浪费，严重时甚至使圆盘元件损坏。

Rotating disks are the basic mechanical element of steam and gas turbines, grinding wheels, circular saws, and computer disk memories. Large amplitude transverse vibration of rotating disks can cause failure of turbine wheels due to wheel-case contact, cutting inaccuracy for grinding wheels and circular saws, the waste in material and head-tracking errors in computer disk memories.

ZL03 2 354312.The innovations include: automatic self-closing and reliably sealed valve structure: the design of duplex valve clack with pilot valve to tackle the problem of reverse seal structured valve being difficult to be opened; an automatic drain control device to automatically drain the remaining water from the hydrant; protective plate provided between the hydrant body and the valve block to serve as a connection between the hydrant body and the valve block, which is the first one to be damaged when the ground hydrant is clashed, and prevent pulling-off of the whole above-ground part of the fire hydrant, so as to properly protect the main parts from any damage. The self-closing and reliably sealed valve now prevents drain of water, and only the damaged protective plate is needed to be replaced before immediate re-operation. Thus the repair work after clashing is very easy and simple.

其创新点为：具有能自动关闭并可靠密封的阀门结构：采用有先导阀复式结构阀瓣设计，解决反向密封结构阀门开启沉重费力的难题；设计自控排水装置，能自动排除栓体内余水；在栓体和阀体之间设计撞裂板，它既起到连接栓体和阀体的中介作用，又可在地上消火栓被撞击时率先破裂毁坏，并使露出地面的栓体不见整体脱落，有效保护各主体部件的完好无损，而此时阀门的自闭式结构可靠密封阀门阻止水源外泄，修复时只需更换损坏的撞裂板即可立即复位投入使用，使被撞后的修复工作变得十分轻松简便。

In traditional, the working probe naturally sustaining repeated bending actions and wear, absolutely needs a mechanism to prevent it from being damaged, caused by the change of the probe's geometry and the increase of the contact resistance. Therefore, in this study, we develop a CMOS-based chip in connection with the electroformed probes to detect each of their counterforce, contact resistance to evaluate if their contact force and coplanarity are controlled within safe range.

传统上，探针常因为弯曲作动和磨耗，使几何形状产生改变，进而电阻值提升，使过大的电流通过探针而烧毁，或因共面度不佳部分探针未能确实接触IC焊垫误判成断路，故晶片的制作重点在於监测探针卡上个别探针的回馈力量，当探针量测IC时，可进行即时探针反作用力、接触电阻的检测，进而了解探针卡工作时受力是否均匀、平坦度是否符合要求等性质。
