On the basis of experiment analyses we would got that, When arc met with chute, it was blocked and had a stagnation, this made hot gas flow incrase near the chute; After arc went into the chute, mental vapor from arc root would lower the dielectric strength near the chute, meanwhile, High value of arc voltage and the corase face of the chute made electric strength increase. These factors might give rise to local restriking near the chute, and made arc voltage drop suddenly.

总结实验结果并加以分析，本文提出了这样的观点：电弧进入栅片时，在入口处受阻后的停滞，会使该区域的热气流增加；进入栅片后，弧根蒸发的金属蒸汽、电弧热气流会降低栅片入口区域的介质强度；电弧被栅片分割后，电压急剧上升，再加上栅片表面的不均匀会使局部区域的电场强度显著增加，这些因素的综合作用会导致电弧在栅片入口附近发生局部重击穿，引起电弧电压电压跌落。

A method and apparatus for increasing the propelling force of pulse engine features that the fuel nozzle of pulse explosion engine is arranged in combustion chamber to close jet tube exit, and the fuel is reversely sprayed out to generate a shock wave barrier near the jet tube for preventing the airflow from flowing out of the combustion chamber, resulting in raising the pressure in combustion chamber and in turn increasing the propelling force.

本发明公开了一种提高脉冲发动机推力的方法和装置，它是通过将脉冲爆轰发动机的燃料嘴置放在燃烧室中靠近喷管出口附近，并使燃料逆向喷出，在燃烧室内靠近喷管附近形成一道阻止气流流出燃烧室的激波，激波的作用是使燃烧室压力升高，从而的到较大的推力。同时由于本发明的结构特别的简单，所以实现非常容易，并且工作效果十分显著。

RESULTS The results indicated that PCF could significantly increase the viability of thymocytes and enhance the activities of SOD, GSH-Px, CAT in cells. PCF decreased the amounts of ROS and the rate of apoptosis in cells. PCF inhibited the morpholog alteration of the thymocytes irradiated by UVB and maintained the ultrastructure of cells in normal. PCF attenuated UVB caused DNA fragmentation in thymocytes. While combined ERKs inhibitor yielded typical DNA fragmentation, co-treatment of thymocytes with PCF and JNKs and p38 kinase inhibitors completely blocked UVB-induced DNA fragmentation.

The results are as follows: the DDM detergent dissolves the Cyt b6f better thanβ-OG detergent does; DDM can keep the Cyt b6f in native state, under which the hemes and Chl a experience specific environment, while theβ-OG make the complex in denatured state in some sort, under which the catalyzed electron transfer activity of the complex

结果表明，DDM去垢剂能使Cyt b6f处于较好的分散体系中，其中血红素和Chl a分子处于特定的蛋白环境中，不会导致Cyt b6f变性；而β-OG去垢剂会使Cyt b6f产生聚合现象，其中的血红素和Chl a与蛋白环境的相互作用减弱，和DDM相比其电子传递活性显著降低，Chl a单线激发态寿命延长，Chl a更容易被光

与城市用地变化有关的土地利用类型也多分布在金昌、嘉峪关、张掖、武威和酒泉 5个地级市所在地区，表明这些区域的城市化过程相对活跃；3城市用地变化对生态环境影响的空间规律表现为：使生态环境原本较差的地区生态环境质量有所增加，而使生态环境质量较好的地区生态环境质量降低；4城镇用地与工矿用地对区域生态环境的影响表现出与城市用地总体基本一致的规律，但农村居民点则对生态环境正、负两方面影响都较为显著；5 城市用地扩展对区域生态环境的影响也体现出与城市用地总体类似的区域分异特征；而城市用地收缩的影响则与此趋势相反。

The resultant cationized pulp fibers can obviously improve the retention of precipitated calcium carbonate filler in the furnish. Adding 2% of CPF （based on oven-dry pulp） can improve the retention of PCC from 61.1% to 83.4%, compared with the retention of PCC only 78.2% by adding 0.05% of CPAM, and also the application of CPF is better than adding EPI-DMA directly. At the same time, CPF can improve the drainage performance of the stock.

制得的CPF能显著提高沉淀碳酸钙填料的留着率，用量为2%的CPF即可使PCC的留着率从61.1%提高到83.4%，而CPAM在最佳添加量0.05%时仅使其留着率提高到78.2%，CPF应用性能优于直接添加EPI-DMA，同时CPF能够改善浆料的滤水性能。
