原因与结果

It indicates that the damnification morphology of K9 glass is cleavage damage, the reason of which is that the hoop tensile stress overtops materials'tensile strength. And the materials'damage threshold is inversely proportional to irradiation time.The mathematical model of in-band CW laser irradiating optical material is established.

结果表明：K9玻璃材料的损伤形态为解理破坏，破坏的原因是环向拉伸应力大于材料的抗拉强度，且材料的损伤阈值与辐照时间反向相关，即激光功率密度越高，造成破坏所需的时间越短。

According to the systematic data on land use gathered in the 1996 survey,based on reverse deduction of the cultivated land area from 1986 to 1996,and deduction of the cultivated land area from 1960 to 1985 by stages by employing yield of grain,this paper redescribed the actual changing trend and character of Chinese cultivated land and analyzed the driving force of the policy relative to cultivated land to cult

结果表明，1949年以来中国耕地资源数量呈现波动性变化，但在1979年之前总体上是增加的，自20世纪80年代起呈现缓慢下滑，1999年后由于生态退耕等原因引起耕地数量迅速减少，由此导致的中国粮食安全问题与耕地安全问题值得关注。

According to the inspection and tests results, it is concluded that the cracks are induced by rutting and fatigue.

结果表明：铺装层的疲劳抗力与高温稳定性不足、层间粘结层较弱、低速超载的大交通等是导致铺装层开裂的主要原因。

Result Reoperative reasons include unresected cysts canceraztion (3 cases);unresected cysts calculogenesis (4 cases);anastomotic stoma between gut and cyst or bile duct stenosis (6 cases);reflux cholangitis(1 case);recurrence cholecystitis (6 cases).

结果再次手术的原因是囊肿切除发生癌变3例；囊肿未切除形成结石4例；囊肿或胆管与肠道吻合口狭窄6例；返流性胆管炎1例；未切除胆囊及复发性胆囊炎6例。

The experimental results showed that the corrosion rate in this system is so low that it can meet the condition to be used in sealed batteries. It was also found that aluminum keeps active to some extent in a wide potential range and its discharge potential is near to that in aqueous solution. The sharp increase of discharge potential, which led to the end of discharge, was probably caused by the deposition of discharge products on aluminum surface.

实验结果表明这一体系中的腐蚀速率极小，以致于可以满足密闭电池的要求；纯铝在这一溶液中可以在相当宽的电位范围内保持一定的活性，放电电位与水溶液体系相近；放电后期电位迅速上升的可能原因是放电产物在表面的堆积。

It is considered that link wear speed on seal surface is proportional to the contacting pressure. The impacting of valve disk on valve seat is the important reason of abrasive wear, and the relative motion of disk is a main reason for errosion wear of pump valve. The cycles per minute is an important factor to influence the valve motion and the impact force.

结果表明，泵阀密封面联接磨损的磨损速度与密封面上的接触比压成正比，泵的冲次是影响阀盘运动规律及对阀座产生冲击的重要因素，泵阀产生磨粒磨损和疲劳磨损的主要原因是泥浆、阀盘和阀座的冲击，冲蚀磨损导致泵阀的刺蚀。

The simulation results show that the speed ratio of the motor mostly affects the total harmonic distortion of the current and the displacement power factor.

仿真结果表明，电机转速比是影响交交变频轧机系统网侧基波功率因数与电流总畸变率的关键原因。

Last season, the NBA had its first do-over since 1982 when Atlanta and Miami replayed the final 51.9 seconds of a Hawks victory because the official scorer ruled incorrectly that Shaquille O'Neal fouled out. The Hawks won the replay, then the regularly scheduled game.

上个赛季，NBA举行了1982年以来联盟的首次重赛，老鹰与热火队被要求重赛一场本来是老鹰取胜的比赛的最后51.9秒，原因是裁判当时误判沙克-奥尼尔犯满离场，结果老鹰取得了重赛的胜利，并也赢下了接着进行的一场常规赛。

The main results are as follows: The environment here is terribly vulnerable, and is facedwith the severe process of desertification and pasture degradation. The tendency of climatebecoming warmer and arider is the background factor of the environment degradation, and theinfluence of the human activities also expedites the process. The main reason that results inthe regional difference of the landscape changes is the the regional difference of the intensityof human activities.

研究结果表明：鄂托克旗生态环境十分脆弱，土地沙化、草地退化问题严重；气候朝干旱化与温暖化方向发展的趋势是生态环境退化的背景因素，人类活动的影响加剧了这种退化过程；不同景观小区人类活动强度的差异是引起景观变化差异性的主要原因。

The results show that, Pian Nui can form the structure of SC in autosomes of a few primary spermatocytes and has more synaptonemal abnormalities.

根据研究结果，作者认为牦牛与普通牛在部分常染色体和性染色体上的差异，使犏牛的同源染色体不能很好地配对形成SC ，是导致不育的主要原因之一。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
