无事实证明的

The aim of the paper is to improve the reliability of HF generator, which is the key to decide the life of HF electrodeless light. At first, I collect and analyze the relative dates, and statistics fault models.

首先进行了与可靠性相关的数据收集与分析，对故障模式进行统计；然后从电路结构、环境应力及容差三个方面进行可靠性分析，从而为关键的可靠性设计提供了依据；接下来的可靠性设计，从电路设计、热设计、降额使用、筛选四个方面逐一解决了可靠性分析阶段发现的问题；最后，我将改良的发生器批量生产，并从中重新收集了可靠性数据进行计算，事实证明改良后高频无极灯的平均寿命已达到6万小时。

The corrugated steel, frameless structure proved to be most blast-resistant of those tested.

槽纹钢板无架结构经事实证明是试验中最能抗爆震波影响的。

At the I past's in consciousness, my these people's always don't be pay taxes, because I only is a in ordinary enterprise the a ordinary worker, pay taxes is big-little businessman, the street pedlar owners and have high take in peoples the things, however our attach America go to visit one's relatives could travel,changed our view, has very much very much the fact can prove, my these ordinary common people,also too is pay taxes people, but also nearly is day-day for the pay taxes,it for my the assemble impression is: nothing don't be obtain you pay taxes the part, nothing don't be obtain you pay taxes the billand bills more,that's mouth say nothing evidence, has bill for act credentials:.

在我以往的概念中，我们这些人是从来不纳税的，因为我只是一名普通企业里的一名普通职工，纳税是大小老板们，摊贩主们和享有高收入人们的事，然而我们的赴美探亲之LU，改变了我的这一看法，有太多太多的事实可以证明，我们这些平头老百姓，也是纳税人，而且几乎是天天地在纳着税，它给我的总的印象是：没有不收你税的地方，更没有不收你税的发票和单据，口说无凭，有单据为证

At first, I collect and analyze the relative dates, and statistics fault models. Then I finish the analysis from three aspects, instruction of circuit, stress of surrounding, and tolerance, thus providing basis of design. The following designs are in progress from four aspects, which are circuit design, thermal design, derating using and screening. At last, I make the update generator in batch process, and collect and analyze reliability dates again. I proved that the life of the improved HF electrodless light is over to 60,000 hours.

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
