In the application of water-saving drilling system, in-hole drilling condition can only be judged by observing pressure change in pressure gauge on the surface with low precision.

节水钻探系统在使用过程中，由于孔内不返水，在地表只能通过观察压力表的变化量来判断孔内工况，精度不高。

通过研究，最终解决通过地表压力变化值来判断孔内工作情况的量化问题，建立初步理论模型，从而更加准确地判断孔内的工况，使这套钻具更快地应用到实际工程中。

Base on the fact that a hard-edge aperture function can be expanded into a finite sum of complex Gaussian functions, the approximate analytical expressions for the propagation characters of Hermite-Guassian beams passing through double rectangular apertured are derived. The approximate analysis uses Collins formula. At last, Matlab illustrates some numerical examples.

基于硬边孔函数能拓展成一组有限复高斯函数的和，研究厄米－高斯光束通过双矩孔的传输特性，用Collins公式分析，用Matlab进行一些数值模拟。

Yimei Voice generation Canadian, and all the respect hole measures to make the Road Hole glenoid the traditional Chinese culture as a whole and the moral core.

溢美之声代代有加，种种尊孔措施，使孔盂之道成为整个中华民族传统文化的道德核心。

Result The Jugular foramen separated into three parts inferior petrosal sinus and glossopharyngeal nerve anteromedially, sigmoid sinus psotero-laterally, and vagus nerve and accessory nerve in the middle.

颈静脉孔为重要的颅底通道，其位置深在，解剖结构复杂，熟悉和掌握孔内各神经血管之间的毗邻关系是施行此区域手术的关键和基础。

The hole greaser is at the center of the cap, because all bearing have W33 grove / hole greaser.

因为所有轴承上都有宽为33的加油孔，故加油孔需在盖子的中心位置。

Once the grid leak the gum is fully populated, each subsequent blade completed a business card printing and membership card making his screen most of the leakage holes will be printed on China and India rubber to PCB.

一旦网不活漏孔被印胶填满后，此后屡屡刮刀达不败一个制卡和会员卡制息旅程，网不活漏孔洋的不小部分印胶不兵被印到PCB不活上。

The grommet on the base of 76117 and 76116 is OK. All of the others are wood, so there is no base grommet.

所以当装配的时候都不在一个位置上，76117和76116有基准孔所以是可以用的，其它的都是木质的，所以没有基准孔。

These dies are made from cast iron with steel inserts for the gudgeon pin holes and the cores.

这些模具组成部分应用了铸铁材质，而中空和活塞销孔部分的抽芯应用了钢材质，这些抽芯可以保证活塞销和内孔部分的部位形状。

I can not make it blossom and suits me
