零点

Especially,the zero-crossing surging of the monopolar SPWM doubleside control is discussed.

并特别讨论了单极性双边控制中的过零点振荡问题。

First, from the point of view of production and management, the importance for developing TTU is pointed out.the status in quo of technology,The direction of progress,The demand of practical and fundamentality in Distribution Automation are analyzed for Transformer Terminal Unit. The function of equipment and technical specification which meet demand of practical duty are indicated; Second, the scheme of synchronous sampling,quasi-synchronous sampling,non-integer cycle sampling,nonsynchronous sampling and algorithm are analyzed in detail. Then,the scheme of nonsynchronous sampling and multi-chunnel is ascertained. Moreover, the method of disposal sampling data for increasing precision which calculate the number of sampling per cycle dramatic by searching zero is introduced. The technique for analyzing data,stating data,storage data for Electrical Power Quality and control scheme for compensation capacitor are explained also. Finally, The scheme and structure of hardware,key circuitry using 80C196 singlechip,the scheme and ideology of software and flow chart of part software is introduced simply.

文中首先从电力生产、管理角度出发，指出了研制配变监测终端的重要意义，分析了配变监测终端的技术现状、发展趋势、现场需求以及在配网自动化中的基础地位，提出了满足实际运行要求的装置功能、技术要求；然后对目前常用的同步采样、准同步采样、非整周期采样、非同步采样的方案和算法进行了详细的分析、比较、筛选，确定了非同步采样和顺序采样的方案，并提出了一种寻找过零点从而动态计算每周采样点数的提高精度的采样数据处理方法，文中对装置中电能质量分析、统计、存储的方法以及补偿电容器的控制方案和投切原则也做了重点说明；最后，对应用80C196单片机系统研制的装置的硬件方案、结构以及关键电路和软件设计思路、方案、部分主要软件模块的流程图做了介绍。

With the ab initio PESs, we calculate the ro-vibrational energy levels of three dimers and their isotopomers using Sinc-DVR method.

预测了三个体系的振动束缚态和波函数，从Ar原子到He原子，零点能依次升高。

The are is interrupted at the first current zero and dose not reignite.

电弧会在第一个电流过零点被切断而不会重燃。

Yesterday Sisi and I went to LingDian restaurant for lunch. Because of no two-seat table, wo had to share the same table with an old man.

昨天在零点餐厅吃饭，但是没有空位了，后来只能和一个一个老爷爷同一个桌。

A large, tapas a la Carte menu will also be available for your choice.

此类小吃零点菜单也为您做好了准备哦！

By combining the cre/loxP and Gal4/UAS systems under the control of brn3a-hsp70, the authors zeroed in on the somatic origin and final projection sites of individual tectal neurons.

通过在转录因子brn3a－热休克蛋白70的控制下结合cre/loxP系统（一种对转入基因进行组织特异性、定点操作的基因重组系统）和Gal4/UAS系统，作者在躯体的起点和个体顶盖神经元的最后投射区域调了一个零点。

By combining the cre/loxP and Gal4/UAS systems under the control of brn3a-hsp70, the authors zeroed in on the somatic origin and final projection sites of indiidual tectal neurons.

通过在转录因子brn3a－热休克蛋白70的控制下结合cre/loxP系统（一种对转入基因进行组织特异性、定点操作的基因重组系统）和Gal4/UAS系统，作者在躯体的起点和个体顶盖神经元的最后投射区域调了一个零点。

Of the zero point shifting, the switching, multi-directional measuring probe with telemetric signal transfer of Messrs.

为了使工件测量系统相对于零点漂移得到对正，采用了带有开关系统和遥感信号转换的雷尼绍 MP16多向测量探头。

The associated factors, clinical signs, treatment and prognosis were discussed. Result: Nine patients (6 female and 3 male) were included in this study. All of the patients were associated with myopia, ranging from -0.5 diopters to -5.0D. Gonioscopy revealed a dense homogeneous pigmented band seen over the entire circumference of the trabecular meshwork in all patients; however, no patients with iris transillumination defects were detected. Two of the patients developed pigmentary glaucoma and were treated with β-blocker, miotics and argon laser trabeculoplasty.

结果：九病例中有六位女性及三位男性，所有的病例皆有近视，分布於负零点五至负五点零屈光度，所有的病例在隅角镜检查皆可观察到浓厚的色素沈积在小梁组织，然而在这些病例并没有发现到有典型之虹膜透光缺损：其中有两例后来发展成色素性青光眼，以乙型阻断剂、缩瞳剂和氩氮雷射小梁整形术治疗后，病情控制稳定。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
