钻进

Hence, we first analyzed and studied the kinematics and dynamics of PDC bit, and that are utilized to analyzed how to hame cutters by PDC bit whirlpool. Onthe based of this, we do the cutting experiments. With the test, we not only think over the influence to force actting on cutters in rock nature, drilling parameter, cuttersdensity distributed, and also wear state of cutters and PDC bit appearance. Because the PDC bit's cutters are repeaded by polycrystalline-diamand and tungsten carbide, the specific property of PDC wear are not alike that of polycrystalline-diamand and not alike tungsten carbide.

因此，本文首先分析研究了PDC钻头的运动学和动力学，并利用分析的结果对PDC钻头的涡动是如何损坏切削齿的进行了探讨；在此基础上，进行了PDC钻头切削齿的受力实验，在受力实验研究中，不仅考虑了岩性、钻进参数、布齿密度等对切削齿受力的影响，而且考虑了切削齿不同的磨损状态、钻头的冠部形状对切削齿受力的影响；PDC钻头的切削齿是由聚晶金刚石层和碳化钨底层复合而成的，它的磨损特点既不同于金刚石的磨损又不同于碳化钨的磨损，因此，在分析了复合片磨损机理的基础上，进行了PDC钻头切削齿的磨损实验。

The loftiest place is that seat of grace For which all worldlings try: But who would stand in hempen band Upon a scaffold high, And through a murderer's collar take His last look at the sky?

至高的地方是那赐福之位，芸芸众生都为此把心操碎可是谁会站在麻绳圈前，高度正好和绞刑架一般，钻进一个刽子手的圈里，夺取他最后看天的权利？

For he that cannot possibly mend his own case, will do what he can, to impair another's; except these defects light upon a very brave, and heroical nature, which thinketh to make his natural wants part of his honor; in that it should be said, that an eunuch, or a lame man, did such great matters; affecting the honor of a miracle; as it was in Narses the eunuch, and Agesilaus and Tamberlanes, that were lame men.

这两种感情都会激起强烈的欲望，而且均可迅速转化成联想和幻觉，容易钻进世人的眼睛，尤其容易降到被爱被妒者身上；这些便是导致蛊惑的要点，如果世间真有蛊惑的话。

Jean Valjean laid a host of ambushes for him; he changed his hour, he changed his bench, he forgot his handkerchief, he came alone to the Luxembourg; Marius dashed headlong into all these snares; and to all the interrogation marks planted by Jean Valjean in his pathway, he ingenuously answered "yes."

冉阿让为他设下一连串圈套，他改时间，换坐位，掉手帕，独自来逛卢森堡公园，马吕斯却低着脑袋钻进了每一个圈套，冉阿让在他的路上安插许多问号，他都天真烂漫地一一回答说："是的。"

One of us lifted something from it, and leaning forward, that faint and invisible dust dry and acrid in the nostrils, we saw a long strand of iron-gray hair.

我们当中有一个人从那上面拿起了什么东西，大家凑近一看——这时一股淡淡的干燥发臭的气味钻进了鼻孔——原来是一绺长长的铁灰色头发。

By coincidence, another squirrel got into a substation 40 miles away in Ironwood, Mich., Monday morning and caused a temporary outage that affected about 1,400 customers in Ironwood and two nearby communities, Elwood said.

爱尔伍德还说，巧合的是，周一上午另一只松鼠钻进了密歇根州爱恩伍德市40英里外的一个变电站，致使电力暂时中断，影响了爱恩伍德市和临近两个社区的1，400位电力用户。

The irreparability of the past: once at a performance of Albert Hengler's circus in the Rotunda, Rutland square, Dublin, an intuitive particoloured clown in quest of paternity had penetrated from the ring to a place in the auditorium where Bloom, solitary, was seated and had publicly declared to an exhilarated audience that he was his (the clown's) papa.

317过去的事是已经不可挽回的了。有一回艾伯特。亨格勒马戏团在都柏林市拉特兰广场的圆形建筑里演出，一名富于机智的小丑身穿色彩斑驳的服装，为了寻找乃父，竟走出马戏场，钻进观众席中，来到孤零零地坐着的布卢姆跟前，在大庭广众之下，向兴奋不已的观众公开宣称：他是他的爸爸。
