Through analyzing the s tressed state of each part of the drill string in borehole,the four main charact eristics and basic reasons of the drill string failure that often occurs and is of general character are analyzed and the feasible,scientific and effective meas ures for preventing these common drill string failure accidents are emphatically proposed in this paper.

文章从分析钻具在使用过程中的受力情况出发，根据钻柱各部位在井内的受力情况，剖析了四种经常发生的、带共性的钻柱失效的主要特征及根本原因，重点提出了比较可行的、科学的预防这几种常发性钻具失效事故的有效措施和看法。

In May, he said, miners were dismayed to discover that 59 mules had died from unventilated mine gas. Some oxygen cylinders were on hand in case of emergencies, he said, but we didn't know how to use them.

&他说，早在五月份，矿工们就惊愕地发现有59头骡子死于不流通的矿内气体，于是氧气瓶被矿工们随身带着以防万一，&可是我们都不知道怎么使用氧气瓶，他说。

The street doors of the houses are still closed, like stingy purses, and the night watchmen sporting shiny new gold braid on their caps look suspiciously at the traveler as he goes by on his way to the station with his knapsack on his back and his unworried, almost slouching walk.

街道两旁门户紧闭，像不愿打开的钱包。巡夜警们盖帽上崭新的金色条带发着光。他们警惕地看着从身边经过的一位旅人，他背着背包、神情自若，悠闲地向车站走去。

Finally, we present an arithmetic of multiplehypocentral, heterogenous dislocation, and a multirupture segment superposition model for simulating the earthquake deformation field. The simulated LOS interferometry map presents the distribution characteristics of the earthquake deformation field better than that of previous studied. Meanwhile, a suit of fault geometric parameters of the earthquake is also obtained by the study. Having a better effect upon simulating asymmetry, great dislocation, macro rupture field, and nonhomogeneity of dislocation than the traditional model, the multisegment method is a progress of this work. It provides a better explanation for the study on hypocentral parameters.

基于上述原因，本文对Okada线弹性位错模型的算法进行了改进，提出了&多震源、非均一位错分量、多破裂段叠加&的线弹性模型，该模型模拟出的形变场干涉纹图较好地体现了地震形变场的分布特征，并由此获得了一套较为完整的地震发震断层的几何学特征参数，为破裂带长度、破裂面方向、破裂面大小等震源破裂特征参数研究提供了较好的解释。
