The research results indicated that the first cross-linking between the HPAM and Cr3+ in ground condition was propitious to reduce leaking of blocking agent in oil layer, and the second crosslink action between acylamino of HPAM and organic phenolic aldehyde can form the high intensity gel and it can endure high temperature.

研究结果表明，HPAM羧基与Cr~(3+)离子在地面条件下的一次交联作用有利于减少堵剂在油层的漏失量，HPAM酰胺基与有机酚醛在地层条件下的二次交联作用，能够形成耐温高强度凝胶。

After the hydrone enters the atmosphere, becomes the water vapor alongwith the air current movement, under the suitable condition, meets thecondensation knot to form the precipitation, descends the ground bythe rain or the snow form.

水分子进入大气后，变为水汽随气流运动，在适当条件下，遇冷凝结形成降水，以雨或雪的形式降落到地面。

Its generated mechanism is that poten-tial instability is touched off by the convergent and thermodynamics near theground in the favourable weather controlled by trough of high altitude.Thatmakes effective potential energy release greatly, forming strong convection.Meanwhile, intensive storms with convection are occurred because of the plentyof moisture flowing into the basin and favourable topograph...

吐鲁番盆地的大降水具有降水时间短、强度大、范围小，雨量集中等特点，它的发生机制是在高空低槽控制的有利天气形势下，地面动力辐合作用和热力作用触发了大气中的潜在不稳定结构，使得大气有效位能大量释放，形成强烈的对流；同时，有充沛的水汽输入盆地，在有利地形条件下，产生强对流暴雨。

To solve this problem, we selected CONGAS condensate oil/gas reservoir evaluation software to establish a triporosity logging response equation based on the triporosity logging response of natural gas. It was used to calculate the gas/oil ratio and movable hydrocarbon density. The calculated oil/gas saturation and gas/oil ratio were crossplotted to obtain a comprehensive logging interpretation chart.

为此，采用CONGAS凝析油气藏解释评价软件，根据三孔隙测井曲线对天然气的响应特征，通过计算三孔隙测井响应方程，计算出地面条件下的气油比和可动油气密度等参数，将计算的油气饱和度与气油比进行交绘，形成综合测井解释图版。

The brightness of dawn filtered down from balconies and cornices in streaks of slanting light that dissolved before touching the ground.

从阳台和檐口上滤下的晨曦形成一条条的倾斜光柱在到达地面之前就淡然溶释了。

When the poisonous pesticide is degraded, it is likely pollute soil and water. If the underground water level is within 6 meters to the ground, the eluviated pesticide may pollute the underground water. Thus we have to be cautious when using pesticide

一切的化合物都具有毒素，当施药隐埋后应考虑到农药对土壤、水体降解过程中，药剂施用毒土形成后的向下淋溶径流降解，当地下水位距地面6米范围内时，向下淋溶径流降解的农药就有可能对地下水造成污染，故所应持极其注重态度对待。

A hydraulic self-sealed swab bing wellhead assembly with anticollision crown;2. An economical and safe casing swab bing tool;3. If sand is not sunk, by operation of swab to build a different pressure between up and down of sunk sand to form a de- terminate pressure stir makes the sand to sink to reach the objective of unstuck.

冲管解卡工艺是将小直径的管柱下入到油管中，在油管中建立液流的循环通道，利用该通道把砂子带到地面，一直冲洗到人工井底，给油管外的砂子下沉留有一定的口袋；若砂子不下沉，可以通过抽汲在沉砂上下建立压差，形成一定的压力激动，使砂子下沉，达到油管解卡的目的。

Observational study and numerical simulation were conducted on a severe dust storm process induced by the intensive development of Mongolia cyclone occurred from 6 to 8 April 2001 in Inner Mongolia.

本次过程深厚混合层的形成是长时间地面加热的结果，这也是特强沙尘暴仅发生在内蒙古中部偏北地区而不是下垫面条件更为适宜的内蒙古西部的原因。
