The water body is usually in the flowing state, the atmosphere oxygen resume includes the molecule diffuseness and turbulence diffuseness. Especially in the slowly flowing water, such as the reservoir and the backwater river, the velocity has only the 10〓m/s level, it is necessary to consider both kind of diffuseness.

水体一般都处于一定的流动状态，其大气复氧作用，既有分子扩散，又有紊动扩散，尤其流速非常缓慢的湖流，库湾回水段水流，流速只有10〓m／s的量级，这种情况下，同时考虑二者的复氧作用是非常必要的。

Based on testing datas in worksite and engineering practice,this paper mainly discussed strata damage movement characteristic, rock properties of weathered zone, qualitative and quantitative analysis of the law of coal layer safety extraction in weathered zone when the coal layer is extracted in efflorescent oxygenized belts.

根据现场观测资料和工程实践，着重论述了风氧化带内煤层开采时覆岩破坏移动特征，风化带岩石属性和风氧化带内煤层安全开采机理的定性、定量分析。提出了风氧化带煤层开采无垮落带；受采动影响后，具阻水和抑制导水断裂带继续发展的双重作用以及移动快、变形大、回宿快、下沉大和适当加大开采厚度等新观点

It would not be easy to enshroud so many targets afterwards and the action might lead to a failure, but I was already in it with no way out. I could only work flexibly, accurately, and effectively.

我心里暗自骂了句：妈的，这回麻烦了，一下干掉这么多人，动静太大了，整不好会把自己搭进去，但事以至此，没办法，只有灵活，机动，伺机而动了。

The position of executer unit in case of the contact rapidly backing to normal position to action contact position.

In this work,based on the principle of microdoppler,the mathematical model between missile and decoy is constructed,and characteristics in microdoppler are analyzed through simulation,thus distinguishing the target from heavy decoys and the missile.It offers a new reassuring way to the discrimination of the real or false targets.Keywords : target recognition;warhead;decoy;microdoppler;micromotion

文中在对微动目标微多普勒分析的基础上，建立了导弹与诱饵的数学模型，采用短时傅里叶变换的方法对回波信号进行微多普勒特征提取，仿真分析了导弹与诱饵的微多普勒特征，通过研究其时频分布特点的差异成功的识别出了真假目标，从而为弹道导弹与重诱饵的识别提供了一个新的有效方法。

In chapter 7, the 2D-distribution of the clutter spectrum in non-sidelooking phased array airborne radar varies with cell range (this can be often called as clutter range dependence), which this kind of nonhomogeneity resulted by range dependence is more serious especially in short range.

第六章提出了一种基于最大似然估计的动目标检测的非均匀方法，首先利用自回归方法对雷达接收数据进行时域白化处理，然后利用最大似然方法逐距离单元估计目标回波幅度，最后由估计结果与自适应门限比较得到检测结果。

As she is such a numskull anyway; so she got a lot of them out and brought them in last night and put them in my bed to keep warm, but I have noticed them now and then all day, and I don't see that they are any happier there than they were before, only quieter.

昨晚，她从池塘里面捞回很多鱼，还要我把这些鱼弄进屋子，放在床上帮它们取暖。可是，据我观察，它们在床上好象并不比在水中时快乐。它们只是静静地躺在那里，一动也不动。

Protection The whole protection scheme for double-circuit lines on the same tower consists of split-phase current differential protection or split-phase composite distance carrier protection and zero-sequence directional comparison protection as main protection, and DPFC distance protection, step zones distance protection and zero-sequence directional over-current protection as backup protection.

2.2.1 。保护整个保护计划的双回线同杆包括分相电流差动保护或分相复合距离承运人的保护和零序方向比较保护为主要保护和DPFC距离保护，加强保护区的距离和零序方向过电流保护作为后备保护。

In this paper ,to overcome the shortcomings in 3MK133 Groove Grinder's hybrid spindle system that the shallow slots of the throttler are easy to be blocked and difficult to be disassembled to clean,we use the throttler which is put on the big-side surface of the conical bearing to replace the traditional throttler, change gap throttling to capillary throttling, and adjust the taper of the conical bearing , oil return way , seals and sealed mode.

针对 3MK133沟道磨床动静压主轴系统中，节流器浅沟容易堵塞及拆卸清洗不便等缺陷，提出采用端置式节流器替代原有的内置式浅沟节流器，变间隙节流为毛细管节流，并相应调整了主轴系统中圆锥轴承的锥度、回油通路、密封装置及密封方式。

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。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
