"LEAD has been understudied relative to heart disease and stroke, but it affects about 10 to 15 percent of older adults and is increasingly recognized to have consequences beyond the classic pain with walking," said noted alcohol-and-health researcher Kenneth Mukamal, M.D., of Beth Israel Deaconess Medical Center in Boston , who led the study.

&下肢动脉疾病原来被认为是心脏病和脑中风引起的，有10－15％的老年人受其困扰，疼痛也不仅仅是走路是出现。&著名的酒精和健康专家马萨诸塞州波士顿贝斯雅各医疗中心医学博士 Kenneth Mukama 说，它是这个研究的带头人。

Grendel writhes about in pain as Beowulf grips him.

哥伦多因为贝奥武夫紧扭它的手臂而痛苦地挣扎。

In this essay, however, I confine myself to the unparalleled 'Aventures', in my view – perhaps apart from Alban Berg's Wozzeck – the only great, though negative 'opera' of the twentieth century.

但在这篇文章里，我只讨论到独一无二的《历险记》。在我看来，与A。贝尔格的《沃采克》不一样，它也许是二十世纪唯一伟大然而消极的&歌剧&。

So in order to improve ROP, the VTK vertical drilling technology of Baker Hughes was introduced. VTK is a kind of closed loop, automatic, and vertical drilling technology, made up of closedloop rotary steering drilling system AUTOTRAK, highperformance X-TREME motor and reliable MWD. It is able to return the well path back to vertical by adopting downhole microprocessors to analyze the measured deviation data and determine the proper force necessary for decreasing the deviation angle to guide the steering rib at the highside to reliably stick out against the upper wellbore.

为提高机械钻速，引进贝克休斯的VTK垂直钻井技术，它是由AUTOTRAK、高性能X-TREME马达、可靠的MWD三种技术开发出来的一种闭环自动垂直钻井技术，能够根据井眼的偏斜，经井下微处理器分析判断，使导向稳定地靠近井眼高边方向导向肋板伸出顶向上井壁，这样使钻头产生合理的降斜力，从而使井眼回到垂直轨道上来。

After the early years they changed bass player and sound, deciding it was also time for a name change.

之后，他们改变了贝司手和健全的初期，它也是决定一个名称改变的时候。

A device for determining molar mass with freezing point depression was improved,which consists of the Dewar bottle,sample container,Beckmann thermometer,and motor stirrer.

介绍一个改进的凝固点下降法测定摩尔质量实验装置，它由保温瓶、凝固点杯、贝克曼温度计、电动搅拌器等几部分构成。

A device for determining molar mass with freezing point depression was improved, which consists of the Dewar bottle, sample container, Beckmann thermometer, arid motor stirrer, Before the experiment, the freezing point of the coolant was controlled about 2℃ below the freezing point of the sample solution by adjusting the composition of the coolant.

Benape said being less than beautiful had no bearing on the European beech tree's potential contribution to a greener Gotham.

贝纳普说，欧洲山毛榉长得不够好看不要紧，不会影响它发挥绿化纽约的作用。

It is mentioned for the first time in the Behistun inscription , written in c.520 BCE, and must have been part of the Persian realms before that.

它提到了第一次在贝希斯敦铭文，写c.520公元前，必须参加了波斯在此之前，境界。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
