They took and shoved the bag through a rip in the straw tick that was under the feather-bed, and crammed it in a foot or two amongst the straw and said it was all right now, because a nigger only makes up the feather-bed, and don't turn over the straw tick only about twice a year, and so it warn't in no danger of getting stole now.

他们拿过袋子，往羽绒褥子底下一张草垫子的裂缝里使劲塞，塞了足足有一两英尺深。还说，这么一放，不会有什么问题了，因为一个黑奴只会整理整理羽绒褥子，不会动草垫子，草垫子一年只翻两回，把钱塞在里面，就不会有被偷的危险啦。

Guiscardo took it, and feeling sure that 'twas not unadvisedly that she made him such a present, accompanied with such words, hied him straight home, where, carefully examining the cane, he observed that it was cleft, and, opening it, found the letter; which he had no sooner read, and learned what he was to do, then , pleased as ne'er another, he fell to devising how to set all in order that he might not fail to meet the lady on the following day, after the manner she had prescribed.

纪斯卡多接过竹竿，觉得郡主决不会无缘无故给他这样东西，而且说出这样的话来。他回到自己房里，检查竹竿，看见中间有一条裂缝劈开一看。原来里面藏着一封信。他急忙展读，明白了其中的究竟，这时候他真是成了世上最快乐的人儿；于是他就依着信里的话，做好准备，去和郡主幽会。

在钢筋混凝土烟囱裂缝加固工程中采用了无粘结钢绞线预应力环箍，对加固过程进行了现场测试，经预应力环箍加固后的烟囱筒壁中建立的环向压应力在环箍处最大，其值约- 1.0 MPa ，环向压应力衰减较快。

Utilizing the equilibria of pull and press and the dispersion between placed and unplaced steel bar specimens, this paper put forward the shrinkage stress-time computing formula and elastic modulus-time computing formula of merchandise concrete that offered the reference for controlling merchandise concrete cracks.

利用拉压平衡和同条件下素商品混凝土试件和配筋商品混凝土试件的收缩差值，给出了商品混凝土时随收缩应力计算公式和以及商品混凝土时随弹性模量的计算公式，为控制商品混凝土收缩裂缝提供了依据。

Facing the concrete feature of Mesozoic vulcanite in Youyangou of Liaohe eastern depression,the paper uses the ratio of P-wave velocities[1～3]——the fractural analysis approach by flexural strength to study the development degree of vulcanite fracture.

本文针对辽河东部凹陷油燕沟中生界火山岩的具体特征，采用纵波波速的比值——"龟裂系数"裂缝分析法[1，2，3]，研究了火山岩裂隙发育程度。

In order to cope with the water channeling in some oil wells, the water blocking process of bridge plug cementing is studied and applied in 5 wells close to be rejected.

但选井时要求压裂层段距边底水有一定的距离，并有较好的隔挡层，否则压裂时裂缝如果延伸至下部水层，则会造成油井大量出水。

At first , without regard to temperature, calculate structure's stress and look for the reason of crack.

首先在不考虑温度荷载的情况下，对闸墩进行结构计算，探求裂缝出现的原因。

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。
