Heat treatment changes the structure of the cobalt binder phase and the properties of the WC-Co hardmetals. The higher the cobalt content in the alloy is, the more effective the heat treatment is. The present work has found that the transformation of α-Co to ε-Co can be depressed by quenching the specimens in oil from 1000℃ and hence the transverse rupture strength of these specimens can be increased. During tempering the quenched specimens, new precipitated phases which have dispersion hardening effect on the cobalt binder phase have been observed

本书为《油气渗流力学》的英文版。全书从驱动力和驱动方式出发，在对达西定律分析的基础上，遵循由浅入深的认识规律.详细介绍了单相不可压缩液体的稳定渗流理论、刚性水压驱动下的油井干扰理论、微可压缩流体的不稳定渗流理论、天然气的渗流规律、水驱油理论、油气两相渗流理论、流体在双重介质中的渗流理论、非牛顿液体渗流理论等。本书可作为石泊工程、石油地质、地下水工程、油田化学等专业本科生教材，也可作为相关专业研究生的参考书，还可供从事油气田勘探与开发的科研技术人员参考

On the morning of 6th October 2002 the French tanker LIMBURG (299,364 DWT) suffered an explosion and fire as she approached the SBM at the Ash Shihr terminal in Yemen. Initially the cause of the explosion and subsequent fire was unclear but it is now considered likely to have been the result of a terrorist attack. Damage was sustained to No. 4 Starboard tank, which at the time contained some

Fred bergsten explains why policymakers need to act now in order to avert the danger of serious damage to the world economy FIVE major risks threaten the world economy. Three centre on the United States: renewed sharp increases in the current-account deficit leading to a crash of the dollar; a budget profile that is out of control; and an outbreak of trade protectionism a fourth relates to China which faces a possible hard landing from its recent overheating The fifth is that oil prices could rise to $60-70 per barrel even without a major political or terrorist disruption, and much higher with one
