Mobile hard disk can not move at will, mobile hard disk and lead plane jumper are general at least a few centimeters, a lot of people copy data at the same time actually, take at the same time in the hand, this is the error with the commonnest you, experience is fluky, your so harum-scarum behavior accumulative total has the possibility 10 times, 30, did not give a business on the spot, but hard disk of day of very possible abrupt some was hanged ahead of schedule, life of normal circumstance hard disk should be more than 35 years, be like what write above advertisement to have average time to failure, allegedly tens of thousands of hour, it is not quite clear that I am written down, when this plaything high speed runs, anyhow must place the platform that stabilizes in to go up.

移动硬盘并不能随意移动，移动硬盘和主机连接线一般至少几十厘米，很多人竟然一边拷贝数据，一边拿在手里，这是诸位最常见的错误，经验并不可靠，可能你这样鲁莽的行为累计有十次，三十次，从来都没当场出事情，但很有可能忽然某一天硬盘就提前挂了，正常情况硬盘寿命应该不止三五年，好象广告上面写的有平均无故障时间，据说几万个小时，我记不大清楚，总之这玩意儿高速运转的时候必须放置在一个稳定的平台上。

In the paper,a fast image retrieval method based on the DCT domain and correlative feedback is presented,which aims at JPEG images and uses color layout descriptors in the MPEG7 standard. As the method only needs entropy decoding,the speed of extracting image features is improved and storage space saved. The experiment result shows that the method has a high retrieval speed and a good effect.

文章针对JPEG压缩图像，结合MPEG 7中建议的颜色布局描述符，提出一种带相关反馈的基于DCT域的快速图像检索方法；该方法只需要熵解码，可提高图像特征提取的速度、节省存储空间；实验结果表明，此方法具有检索效率高、检索效果好的特点。

Ship speed was first calculated by dropping overboard a log attached to a reel of line knot ted at regular intervals; the number of knot s exposed while the log drifted and a sandglass emptied gave the vessel's speed in knot s.

船的速度最早的计算方法是往船外丢上一节木头，上面绑着一捆绳子，每隔固定的间距打个绳结；当木头漂浮而暴露在外绳结数目，加上沙漏的时间，就得到船的速度，称为节。

Since the dot matrix printer has a medium-resolution and print speed, supplies cheap, at the same time also has a number of high speed jump lines, copy print, wide-format printing, maintenance, etc, are still in the Office and a transaction print reports, invoices, and so on of the type aerocraft.

由于针式打印机具有中等分辨率和打印速度、耗材便宜，同时还具有高速跳行、多份拷贝打印、宽幅面打印、维修方便等特点，目前仍然是办公和事务处理中打印报表、发票等的优选机种。

This machine use the dry and clean constringent air as energy、through airflow high-speed eject to make the grinder indoor be a grinding, classification round surface and be a pressure difference indoor then raw materials are automatically inhaled the indoor of grinder with the help of ultrasonic airflow what 4-16 spray head eject (producing the impacted energy E=1/2mv2), raw materials rotate at a high speed on the classification round surface and bring the litter store and make the raw materials granules hit and rub together to attain the supper fine materials.

本机组以干燥洁净的压缩空气为动力源，通过气流高速喷射，使粉碎室内形成一个粉碎、分级圆面，并在粉碎室内形成压力差，则物料自动吸入粉碎室，在4到16个喷头所喷出的超音速气流作用下（产生冲击能E=1/2mv2），物料在分级圆面上作高速通常在2-3马赫内，对于硬度低、脆性物料工作压力可低到0.6-0.7MPa。

A senior captain demand of company of British Speed Ferries of 38 years old is thought of, a self-satisfied working circumstance put Facebook, drive for example when the channel of catamaran come-and-go Yinglun that carries 800 people and 200 cars, although the body when his job fastens 800 human life, but enjoy snacks carefree and contently however: Dip in at the same time sauce eats potato piece, one canister life-giving drink is put in nicety on the side of instrument board, still place a few fastfood.

英国Speed Ferries公司一名38岁的资深船长索思，洋洋自得的把工作情况放上Facebook，例如驾驶搭载800人以及200台车的双体船往来英伦海峡时，虽然他工作时身系800条人命，但却悠然自得地享用零食：一边蘸酱吃薯片，把一罐提神饮品放在精密仪器板旁边，还放置一些小吃。

The effect of the tool composition on the friction and wear behavior was investigated,and the morphologies of the rake face and rear face of the tool cutting the steel in air and nitrogen were observed on a scanning electron microscope. It was found that the Al_2O_3/TiB_2 tool was dominated by adhesive and abrasive wear in low speed dry cutting; while in high speed dry cutting,the tool was characterized by oxidation wear. An oxide layer of TiO_2 was formed by way of the oxidation of the reinforcing agent TiB_2 at a very much high cutting temperature, which contributed to greatly reducing the friction coefficient and increasing the antiwear life of the tool.Such a friction-reducing and antiwear behavior of the oxide layer was enhanced with increasing content of TiB_2 in the tool composite. However,the tool showed a relatively poorer wear resistance in N_2 than in air, because N_2 acted to retard the oxidation of the TiB_2 and the formation of the oxide layer on the tool rake face.

结果表明：低速干切削时，Al2O3/TiB2陶瓷刀具的磨损机制主要表现为粘着磨损和磨料磨损；而在高速干切削时，刀具的磨损机制主要表现为氧化磨损，刀具表面经由氧化反应生成具有润滑作用的反应膜而起到固体润滑作用，从而使刀具的耐磨性能提高，随着TiB2含量和切削速度的增加，反应膜的减摩抗磨作用增强；而在切削区通入氮气时，由于刀具表面氧化膜形成受阻，刀具的抗磨能力有所降低。
