常到

The technical characteristic of a pendulum drill assembly is to lose "penetration rate"in order to get"dropping angle", but sometimes a pendulum drill assembly can't meet the need of drop—off hole angle, which results in longer completion well cycle and more drilling cost.

防斜打直是常遇到的钻井技术问题，防斜的钻具组合是满眼钻具，纠斜的钻具组合是钟摆钻具，当满眼钻具满足不了井斜控制的要求，就必须强迫起钻换钟摆钻具，而钟摆钻具的技术特点是损&快&保&直&，有时还达不到纠斜要求，导致较长的建井周期和较高的钻井成本。

There were six themes in this study. First of all, the geometry of in-vivo human pinna and ear canal was measured non-invasively. The 3D model of pinna and ear canal was reconstructed and then measured based on the image processed by HRCT. Second, the 2D curvature of in-vivo human ear canal was measured non-invasively. The angles and curvatures of superior and inferior walls of first and second bends were measured. The 2D curvature of ear canal was computed by sine and cosine laws. Third, the in-vivo human ear canal was reconstructed by RE. The distribution of sound field was analyzed by FEM. The data obtained in this study can be the reference for clinicians and audiologists. Fourth, the 3D model of earmold of hearing aids, including the ear shell and the housing, was reconstructed by RE based on the image of in-vivo human ear canal obtained by CT.

本研究主题其四，对於听力受损之患者往往皆须选配助听器帮助其放大声音，其中耳模是助听器的外壳，也是接触到耳朵的仪器，而耳道型助听器系位於耳甲艇及耳甲腔延伸至耳道第一弯道处，在制作耳模必须利用灌模方式来取得紧配之耳模，其中耳模在助听器的使用过程中，常因耳模松脱，无法与人耳道紧密配合而造成漏音，因此，利用活体人外耳道电脑断层影像，重建耳道型助听器耳模之三维立体模型影像，其中耳模包括了耳壳及耳模内部空间，并进行几何外型量测，探讨耳道型助听器之体容积大小，也提供了制作耳模时快速、精确度高、减少翻模及修模次数，可减少误差率之方法。

Did Pearl arrive at an age that was capable of social intercourse, beyond the mothers ever-ready smile and nonsense-words!

珠儿已经长到不满足于母亲脸上常挂着的微笑和嘴里唠叨的闲言碎语，能够与社会交往的年纪了！

Did Pearl arrive at an age that was capable of social intercourse, beyond the mother's ever-ready smile and nonsense-words!

珠儿已经长到不满足于母亲脸上常挂着的微笑和嘴里唠叨的闲言碎语，能够与社会交往的年纪了！

How soon -- with what strange rapidity, indeed did Pearl arrive at an age that was capable of social intercourse beyond the mother's ever-ready smile and nonsense-words!

好快啊，真是迅速得出奇呢！珠儿已经长到不满足于母亲脸上常挂着的微笑和嘴里唠叨的闲言碎语，能够与社会交往的年纪了！

The results showed that the content of soil organic matter, total nitrogen and total phosphorus increased in different secondary succession stages from scrub grass to evergreen broad-leaved forests.

结果表明，从灌草丛到常绿阔叶林的不同演替系列群落土壤的有机质、总N、总P含量总体呈逐渐升高的趋势。

By the 1920s, accordions became popular, and they were also used in Cajun and Creole music because they were loud and could be easily heard.

到了1920年代，手风琴广为流传，而卡津及克里奥尔音乐也常使用这个乐器来演奏，因为它的声音响亮、容易听到。

When Dr. Mark Alberts, director of Duke University Medical Center's Stroke Acute Care Unit, urges doctors in smaller communities to take stroke treatment seriously, they often say,"I can't leave my busy practice to rush down to the hospital, read a CAT scan and decide whether a patient needs t-PA."

杜克大学医学中心的中风紧急治疗组的负责人马克·艾伯茨医生督促小型社区的医生们认真对待中风治疗时，他们常常会说：&我不能放下手中正忙着的事情匆忙跑到医院，读造影扫描报告，决定病人是否需要t-PA治疗。&

He had professional aphorisms, which he inserted into his wife's mind.

他常把职业方面的一些秘诀灌输到他女人的脑子里。

For the nobler plants are valued for the fruit they bear at last in the air and light, far from the ground, and are not treated like the humbler esculents, which, though they may be biennials, are cultivated only till they have perfected their root, and often cut down at top for this purpose, so that most would not know them in their flowering season.

因为那些更高贵的植物的价值是由远离地面的、最后在空气和日光中结成的果实来评定的，而不是像对待那低卑蔬菜的那样。蔬菜就算是两年生的植物，那也只是被培植到生好根以后，而且常被摘去顶枝，使得许多人在开花的季节都认不得它们。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
