查询词典 hole

This model considers the flow of energy between two regions around the black hole : an inner region that is close to the so--called event horizen (the boundary beyond which even light cannot escape ), and an outer region that includes the black hole's fuel source-- the young stars--extending up to a million times father out .

此模型分析围绕在黑洞周边的两个区域间的能量流：内部的区域接近于视界（一个理论上的边界，超过此边界甚至光都无法逃脱黑洞的吞噬），外部区域包括黑洞的燃料源——年青的恒星——并继续扩展数百万倍。

METHODS: Embryos were transferred to oviducts of 106 recipients by the traditional method (tearing the bursa open over the infundibulum of oviduct) or the improved method (puncturing a hole in bursa with embryo transfer pipette and blowing embrys into oviduct through the hole).

目的： 通过将传统的撕破囊膜进行小鼠胚胎移植的方法改为囊膜穿刺，以期提高胚胎移植的成功率。

The conclusions can be drawn through numerical simulation: The hydrate-forming region becomes small with increasing circulation rate and inhibiter concentration, and it is possible to make the hydrate-forming region away from sea floor by increasing circulation rate and inhibiter concentration, thus preventing blowout preventer lines from hydrate plugging; the decrease in gas volume fraction in the annulus due to hydrate formation reduces pit gain, which can delay the detection of well kick; the possibility of hydrate presence at a relatively low gas production rate is much greater than that at a relatively higher production rate; the bottom hole pressure is affected little by hydrate phase transition, and it is allowable not to consider hydrate phase transition when the bottom hole pressure is calculated; shut-in casing pressure cann't truly reflect gas kick due to hydrate formation and the situation is getting worse with time

模拟计算结果表明：溢流期间，天然气水合物的生成区域会随着循环流量的增大或抑制剂浓度的提高而减小，可通过增大流量和抑制剂浓度使水合物的生成区域脱离海底，减小防喷器管线被堵塞的危险；水合物的生成使环空中气体体积分数降低，泥浆池增量减小，给溢流检测带来延迟；当检测到有气侵发生时，水合物藏分解速率比较小时，井筒中生成水合物的可能性要比分解速率大的情况下更为严重；水合物相变对井底压力的影响较小，在工程中计算井底压力时可以忽略；由于天然气水合物的生成使得关井套压值不能真实反应气侵情况，而且随着时间的增加情况会更加严重。

This article analyzed the stress and vertical stress integral curve of the core of bottom hole through finite element software,we found the rock of the bottom hole was " convex" during gas drilling ,and the effecting scope of the down stress was large than the conventional drilling fluid.

采用气体钻井时机械钻速较高，目前已被钻井界普遍认可；但对气体钻井是如何提高机械钻速的研究还不多。

Sowing technique: Firstly must hasten germination, conduct sowing immediately when white bud shows on the seed; sprinkle 2 tons of farmyard manure with 30 Kg of compound fertilizer or 15 Kg phosphate fertilizer underneath the sowing location, then conduct ridging, sowing and film covering; interplant spacing 30-40 cm, hole sowing with 1-2 seeds per hole, about 1800 seedlings on each Mu of land.

二、播种技术：首先要催芽，当种子露出白尖时应立即播种，2吨农家肥加30公斤复合肥或15公斤磷二胺，洒在播种位置下面后再起垄、播种、覆薄膜，株距30-40公分，穴播每穴1-2粒，亩保苗1800株左右。

During drilling process, forward and backward redressing can be played the role to repair and maintain the wall of a well, making trajectory of borehole as far as possible to achieve ideal leading to drilling difficultly because of hole shrinkage, and so on, at the moment , the forward and backward redressing of this stabilizer can be played cutting, to eliminate hole shrinkage phenomenon, thus saving time and cost for drilling.

可在钻起过程中起到休整井壁的作用，使井眼轨迹尽量达到理想状态，防止出现狗腿现象。特别是在起钻过程中，往往由于井眼缩径等原因导致起钻困难，此时，该稳定器上的倒划眼齿可起到切削作用，以消除缩径等现象，从而为钻井节省大量时间和费用。
