Firstly, this paper analyzes and summarizes the research situation of resonant soft-switching technique and main topologies. And it indicates the main advantages and disadvantages. Then it pays more attention to analyze the parallel resonant DC link circuit theory and operating modes. It also analyzes how the resonant circuit realizes the resonant process. This paper also simplifies the control part design of the parallel resonant DC link soft-switching inverter by DSP.

本文首先对谐振软开关技术的研究现状和各种主要的拓扑结构进行了分析、综合、总结，指出了各自的优缺点；着重对并联谐振直流环电路的工作原理、电路工作模式、软开关实现机理及谐振参数的确定等进行了深入详尽的分析；利用DSP的灵活调节特点，有效地简化了并联谐振直流环软开关逆变系统的控制环节设计。

The Communists have learned that trying too hard to influence political affairs on the raucously democratic island only backfires.

It, thereby, results in imaging degrading, and engenders blurring imaging. The paper analyses a real process about image blurred as a result of object motion, reveals an intrinsical cause about image-degraded owing to object motion, and establishes blurring-model by which one dimension and two dimensions uniform velocity rectilinear motion result in image blurred abide.

为了有效地恢复运动模糊图像，从像素运动的角度分析了因运动造成的图像模糊的实际过程，并首先揭示了运动造成图像降质的内在原因，然后根据模糊图像像素间的关系建立了一维和二维由匀速直线运动所造成的模糊图像的模糊模型，并依据图像降质过程的逆过程推导出恢复模型。
