准周期的

A first order quasi phase matched periodically poled LiNbO 3 for SHG with 6.5 μm period, 12 mm length, 10 mm width and 0.5 mm thickness has been successfully fabricated by applying an external electric field at room temperature from an high pulsed voltage generator. About 18 mW of CW 0.532 μm green light was obtained pumped by an 1.1 W of CW 1.064 μm Nd∶YAG laser with end coupling, which corresponds to 1.6% power conversion efficiency.

通过高压脉冲电场极化，制备了周期为6.5 μm、长为12 mm、宽为10 mm、厚为0.5 mm的一阶准相位匹配周期性极化铌酸锂；由1.1 W连续1.06 μm Nd：YAG激光器抽运，在5°时产生了约18 mW、0.532 μm的倍频连续绿光，其对应的二次谐波转换效率约为1.6%，二次谐波的归一化转换效率约为1.5% cm-1W-1，相当于79%的周期性极化铌酸锂的理想非线性系数。

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。

I am of September 18 is quasi-normal menstruation within 30 days of the cycle, the results did not come yesterday, I have to buy the paper, a weak line, basically can not see this morning is, and do not know if pregnant ?

我是9月18日的月经平时很准的30天的周期，结果昨天没来，我就去买了试纸，很弱的一条线，基本上看不见，今早也是的，不知道是不是怀孕？

Ah, I am also a July 28 of 月经, you should be able to test the bar, most of them are good pregnant, my cycle is 28 days there have been relatively quasi-dare to August 24, when not to, I on the test, then there are two lines to the hospital on the 26th good for blood to confirm the pregnancy, then a few days I am also a breast nipple pain, especially when touched, as well as the past two days on my left breast around the nipple long a few small granules of the small point that seems to look at this line is like a reflection of early pregnancy

真巧啊，我也是7月28号的月经，你应该可以测了吧，多半是好孕了，我的周期是28天，比较准所以本来敢8月24号来的，当时没有来，我就测了一下，有两条线，26号到医院去抽血确认好孕了，那几天我也是乳房乳头很痛，特别是碰的时候，还有就是这两天我左边乳房乳头周围长了几个小的颗粒状的小点，看网上说的好像这个也是孕早期的反映样
