Section method is to split the pit slope surface into several trapezoids so as to calculate their surface area;through a digital survey of the pit slope surface,a numerical elevation model is set up,on the surface the triangular mesh is built,and all the triangular meshes are piled up to get the surface area.

小三角锁法是通过对宕口坡表面数字化测量，根据测量数据建立数字高程模型，并在表面建立小三角锁，对所有小三角的面积累加得到面积的一种方法。小三角锁法大大提高了计算的准确度和效率。

The result showed that the surface architecture and ultrastructure of I.punctatus ' gill and secondary gill lamellae were similar to those of other teleosts. The surface of gill arches and gill rakers was covered with pavement cells which were characterized by circular microridges, and secreting-holes were found among cells on the surface of gill arches. The base part of gill rakers were bigger in terms of diameter. The pavement cells' surface of gill filaments' middle part was characterized by microridges with fine lateral protuberances on both sides which were either fused or interruped, while the microridges disappeared on the pavement cells' surface on both top and base parts of gill filaments, forming dense granulated protuberances. The height and interlamellar space of secondary gill lamellae in I.punctatus were relatively higher and bigger, respectively.

Ceilings should be ac-cessible for cleaning, and ideally, the surface should he coved where ceilings and walls meet In many food-production areas, the ceiling must have thermal in-sulation This may be necessary either to prevent surface condensation or to reduce the energy costs of maintaining low environmental temperaturesWalls should also be insulated, to prevent surface condensation They should be free from rising damp and be protected, where appropriate, from damage by forklift trucks, by use of a guard rail In modern factories, there is always a coved surface where walls meet the floor It is also usual for there to be a coved surface where walls join at right angles.

A series of erosion-corrosion test has been done to J55 steel under the influence of current of gas-liquid phase by indoor self-made devices, and the corrosion mechanism of current of gas-liquid phase to oil pipe's inner surface has been got. The results show that oil pipe's inner surface will be corroded fleetly by liquid medium and corrosion products will form on it. But at the same time, the corrosion products or protective layer will be removed from the inner surface of steel pipes under the alternate impact of high speed gas and liquid flow, and on this bare steel surface corrosion film will form again and be removed again. Thus, by these ways the corrosion is exacerbated. Surface erosion-corrosion failure comes into being with the circulation of this process going on.

本文主要在气液两相流作用条件下，通过室内自制装置，对管材钢J55做了系列冲刷-腐蚀试验，结果表明，气液两相流对钢管内表面冲刷－腐蚀的机理是钢管内表面会受到液体介质的快速腐蚀，生成腐蚀产物，同时钢管金属表面不断被具有高流速的气液相交替地冲击，不断地从金属表面脱去保护膜或腐蚀产物，裸露的钢表面又会被介质快速腐蚀形成腐蚀膜后，再被两相流冲掉，如此反复，造成管内金属表面膜的连续破坏，使腐蚀加剧，最终导致钢铁表面的冲刷腐蚀失效。

A hard fate; took a hard look; a hard bargainer ; a hard climb.

51 Yrs ones were the diabolo comparison group. The experimental group had to participate in rope-jumping or diabolo exercise training, consisting of 60 min/session, 3 times/wk, for 16 consecutive weeks.The intensity of rope-jumping exercise is between " Hard (15)"and" Very hard (18)"and the intensity of diabolo exercise is between "Somewhat Hard (13)"and"Hard (16)"by rate of perceived exertion scale.

This so-called when necessary, there are two, first, the factory hard drive, hard drive works on a low-level format the hard disk; the other is when the hard drive certain types of Bad Track, the use of low-level format to achieve a certain degree of the role of mitigation, or shielding.

而这个所谓的必要时候有两种，一是硬盘出厂前，硬盘厂会对硬盘进行一次低级格式化；另一个是当硬盘出现某种类型的坏道时，使用低级格式化能起到一定的缓解或者屏蔽作用。

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。

A new general kinetic equation was derived in which the effect of the removal of condensation water was taken into account completely, and was applied to the polyesterification kinetic study of AA/HPHP and AA/NPG. It was found that the reaction order of self-catalyzed polyesterification was not constant. For these polyesterifications, the reaction order was 2.5 at a low temperature, while 3.0 at a high temperature.
