CNT emitter has larger emission current than silicon-based emitter due to its high aspect ratio geometry. The results show that emission mechanism follows the Fowler-Norheim law.

从模拟结果我们可以看出场发射机制确实有遵守Fowler-Norheim规则，奈米碳管和矽基场发射器之间的差异，主要是奈米碳管其高深宽比的几何形状所导致较大表面电场会喷出较大的电流。

Therefore, the research on Eustachian tubes Function Instrument can push the study on Eustachian tube.

但目前尚未有采用计算机运作的实用检测仪器可供临床使用，所以咽鼓管功能测定仪的研制开发，将会进一步推动国内医疗单位对咽鼓管功能研究的发展。

From just began to do a website to calculate to now will also have 56 years, remembered 2 years having individual homepage, that is whats do not understand, had not been in charge of on the free space that did page of a few Html to put Hu Yi with Dreamweaver, do not know to have tally even this thing, of course more do not know to be able to bring discharge through Baidu, feel amused namely at that time, also had not wanted to be able to make this group later.

从刚开始做网站到现在算来也有五六年了吧，记得02年就有了个人主页，那是什么都不懂，用Dreamweaver做了几十个html页面放到虎翼的免费空间上就没管过，甚至都不知道有计数器这个东西，当然更不知道可以通过百度带来流量了，当时就是觉得好玩，也没想过以后会做这一行。

Then the breakdown mechanism was introduced to explain the results.It is found that the optimum polarity combination is heteropolarity and the best scope of the ratio between trigger voltage and self-breakdown voltage is 30%~50%.

实验结果表明：新型触发管开关获得最佳触发特性所需的极性组合应为异极性组合，触发电压幅值范围为自击穿电压的30%~50%，为兼顾触发电流和保护触发器，触发电阻值应为50~100 Ω，验证了触发管开关击穿机制的已有认识。

This was important back in the days of iconoscope cameras which were interlaced in the capture the same as the CRT tubes used for display, because these cameras had the same constraints as CRTs as far as interlaced video is concerned.

因为这些相机有与影像管相同的限制就使交织录影带来说，所以这被在抓取相同於作为展览的影像管管使交织的映像管相机这几天是重要的背面。

The collection of 1.2 specimens the method uses tailor-made palace neck canal to brush outside palace neck mouth and palace neck canal rotate 5 weeks, collect fall off inside the pyxis that the cell washs his Cheng Youbao to put liquid, apply Xin Baishi 2000 full automatic after production opportunity has production, artificial cling to family name coloring, optical microscope issues observation, use TBS to report means reports.

对89例细胞学阳性病例行阴道镜检查及镜下活组织病理检查。1.2标本的采集方法使用特制的宫颈管刷在宫颈外口及宫颈管旋转5周，收集脱落细胞并将其洗入盛有保存液的小瓶内，应用新柏氏2000全自动制片机进行制片后，人工巴氏染色，光学显微镜下观察，采用TBS报告方式报告。

Often divided into two types:(1) sine wave oscillator, according to the network oscillation frequency of the different loop selected further divided into RC sinusoidal oscillator, LC sinusoidal oscillators, quartz crystal oscillators, voltage-controlled oscillator, voltage-controlled crystal oscillator and other forms;(2) non-sinusoidal oscillation device, also known as relaxation oscillator, is the use of capacitor charging and discharging and active device (transistor, FET, single-junction transistor, etc.) to generate the pulse-off square wave, rectangular wave, triangle wave, sawtooth wave, or these basic waveforms synthetic waveform and its frequency by the LC time constant charge and discharge circuits to decide.

常分两大类型：（1）正弦波振荡器，根据振荡环路中选频网络的不同，又分为RC正弦波振荡器、LC正弦波振荡器、石英晶体振荡器、压控振荡器、压控石英晶体振荡器等多种形式；（2）非正弦波振荡器，又称张弛振荡器，是利用电容充放电及有源器件（晶体管、场效应管、单结晶体管等）的通断来产生脉冲方波、矩形波、三角波、锯齿波或这些基本波形的合成波形，其工作频率由LC充放电电路的时间常数来决定。

The lack of amplification in these tubes could be caused by erroneous spermpicking,as well as by the losing of sperm cell in followed analysis procedure.

大约有20％的管中含有分析样品的精细胞，其余的管是空管。

METHODS: Bone of limbs were obtained under sterile condition, washed by PBS, centrifugalization, and dropwise into centrifuge tube containing 1.073 g/mL Percoll separating medium, centrifugalization, and then adding L-DMEM containing 10% fetal bovine serum, benzylpenicillin sodium and phytomycin, cultured in a incubator at 37 ℃ with 5% saturated humidity. The culture medium was renewed after 48 hours, and non-adhesive cells were removed.

无菌条件下截取流产胎儿双侧四肢骨，PBS冲洗髓腔，离心去脂肪及上清液，L-DMEM重悬细胞，沿管壁缓慢滴加至底部有等量1.073 g/mL Percoll分离液的离心管中，离心后吸取中间界面白膜层，加入含体积分数为10%的胎牛血清、青霉素钠、链霉素的L-DMEM完全培养基，接种后置于37 ℃、体积分数为5%的CO2饱和湿度孵箱内培养。48 h后换液，去除未贴壁细胞，以后每2 d换液一次。
