The results indicate that the free radical activity in kidney tissue increases significantly after exercise. As for dynamic changes of LPO, SOD and GSH-Px index based on four time tests, endurance exercise may increase the antioxidative enzyme activity in Kidney tissue, and as a result, it scavenges much more free radical resulting from exercise and enhances the ability for anti-free radical.

大鼠肾脏组织在运动结束后即刻自由基作用明显加强，从其在运动结束后4次测得肾脏组织LPO、SOD、GSH-Px和尿TP排出率指标所形成的动态变化看，耐久性运动可以提高大鼠肾脏组织抗氧化酶活性，从而清除运动时产生的大量自由基，提高大鼠肾脏组织对抗自由基的能力。

电动机通过三角皮带把运动传给大皮带轮，再经过两级齿轮减速后把运动传给偏心齿轮，连杆的上端装在凸轮上，下端与滑块连接，这样通过连杆把偏心齿轮的旋转运动变为滑块的上下直线往复运动。

The design of the dry-dock falling gate"s structure is researched, and integrates the disquisitions and analysis on the dynamic characteristics about dock gate, in order to make the cabin design more visualizing.(2) The emphasis of this paper is the influence of the water hole and gas hole in the tidal cabin and the influence of the drain of the air-operated cabin.(3) In this paper, the building method of the dry-dock falling gate"s parametric model is studied and the dynamic analysis is accomplished in ADAMS, furthermore, the rising-and-falling angle curve is drawn while the dry dock gate is rising and falling.(4) The paper is based on the apprehension of the past theories and researches about air-operated dry-dock falling gate, and is explicated by hydraulic rationales and rising-and-falling mechanical principles. This software is developed by inner programming language in ADAMS and VC. This design could shorten design cycle.
