Seismicity trend before the earthquake was forecasted according to seismicity feature and commensurable characteristics of strong earthquake activities of Sichuan and Yunnan areas.Since Oct., 1995, a lot of kinds of the anomalies with large amplitude, such as radon and CO2 contents in groundwater and groundwater level etc.synchronized in a wide range of western Yunnan, especially along Zhongdian—Nanjian seismic area. The characteristics of these short-term anomalies are introduced and analysed.

根据川滇地区地震活动特征和可公度性计算结果，在该次地震前对地震大形势进行了预测。1995年10月以后，滇西北地区出现了大面积、大幅度、多手段的同步异常，其中以水氡、水位和CO2异常为主，沿中甸─南涧地震区分布较为集中。

The velocity of the change has been remarkable,' says Tom Hoffman, senior vice president for external affairs for U.S.-based coal supplier Consol Energy Inc., which he says is considering holding off on some commitments to supply coal to see if prices rise even further.

在石油方面，直到本世纪初中国的工业飞速发展之后，中国才开始对全球石油市场产生重要影响。2004年中国大面积出现电力短缺，许多工厂被迫购买柴油作为备用发电燃料，致使中国对进口石油的需求增加，在这之后世界油价出现了大幅飙升。

Because the backscattering coefficient is constant, Amazon tropic rain forest is the important calibration region.

This broad weld will improve the strength of the constantan/ copper junction and provide a large area pad for welding to third party base materials.

这种大面积的焊接会增加康铜与铜接合的强度，从而提供一个大范围的焊接点来与第三方基体材料焊接。

The preliminary results showed that the atmosphere contaminator mainly contained SO\-2, NO\-\%x\% and suspended granule. Which caused large area acid rain with high frequency. As pollution became more serious, there were decreases in pH value and increases in the content of SO\+\{2-\}\-4 and Al\+\{3+\} in forest soil; the chlorophyll concentration also would decrease...

初步结果表明：大气污染引起珠江三角洲地区发生大面积、高频率的酸雨，主要的污染物有SO2 、NOx、悬浮颗粒物等；随着污染程度的增大，森林土壤pH值降低，SO2 - 4和Al3+质量浓度增大；马尾松、湿地松叶片叶绿素含量降低，生长衰退甚至死亡；但不同树种对大气污染敏感程度不同，种植马占相思比马尾松更能增加林地对酸雨缓冲力和提高土壤肥力。

A novel on-line measurement method for continuous wave high energy laser beam is presented.

摘 要：提出了一种大面积连续波高能激光光束参数的在线测量方法——环形光刀扫描测量法。

This paper makes an analysis of the Doppler speed charts of clear weather and the echoes of large-area precipitation. It also singles out the Doppler speed charts of typical wind fields. In addition, this paper analyzes Doppler radars detecting process of the strong convection current weather system. It also conducts a thorough analysis of Doppler echo features of some hazardous weather, such as cell storm and downward storms. Based on this research and analysis, the paper reaches some important conclusions concerning the detecting methods using Doppler radar and the analysis of the information gathered by Doppler radar.

本文通过分析晴空和大面积降水回波的多普勒速度图像，归纳总结出了典型风场的多普勒速度图象，并着重分析了多普勒雷达对严重危害飞行安全的强对流天气系统的探测，特别是深入分析了超级单体风暴、下击暴流等灾害性天气的多普勒回波特征，得出了多普勒雷达对灾害性天气进行探测的方法、雷达资料分析应用等方面许多有益的结论。
