The object, known as P/2010 A2, was circling about 90 million miles from Earth inthe main asteroid belt between Mars and Jupiter when it was spotted bythe Hubble Space Telescope
哈勃望远镜锁定P/2010 A2时，这个物体正在距地球约九千万英里的火星和木星之间主要小行星带盘旋。
A case history of the application of the P-wave reflection method in that area to investigate the bedding plane of bedrock, karst cave, fault and the distribution of the dissolution belt is given.
文中给出了该区P波反射法探测基岩界面、溶洞、断层和溶蚀带分布的应用实例。
Furthermore, the P-S-N curves of D type V belt are plotted and the distribution of limit stress are deduced.
还根据所得寿命分布作出了D型V带的P-S-N曲线，并据此推断出极限应力的分布规律可以用威布尔分布或正态分布描述。
