Electron-Doping by Different Alkali Azides in Layer-Structured Crystals of β-MNCl M=Zr, Hf

篇名 不同碱金属叠氮化物对层状晶体β-MNCl电子掺杂的影响

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.

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。

Concentrated, buffered, and dilute hydrofluoric acid were utilized as etchants for SiO2 and SiNx:H. A high etching selectivity of SiO2 over SiNx:H was obtained using highly concentrated buffered HF.

浓氢氟酸、缓冲氢氟酸和稀释氢氟酸被用作氧化硅和氮化硅的刻蚀液，使用高浓度的缓冲氢氟酸可以获得较高的选择比。

First comes the mixing section, where you will find high-quality, discrete microphone preamps, new, dustproof ALPS faders (specially developed for the PowerMate) with very high attenuation even in the HF range, 48V phantom power switchable to the channels in groups of six and a dynamic range that would put most dedicated professional mixers to shame.

首先是非常高的衰减混合部分，在这里您可以找到高品质，离散麦克风前置放大器，新，防尘阿尔卑斯推子（专为PowerMate开发），即使在高频范围，48V幻像电源切换到组的渠道六年的动态范围，将致力于把最专业的搅拌机耻辱。
