小秦岭东闯金矿区花岗岩浆活动的性质

东闯金矿区中生开岩交活动的特征是小秦岭地区这一时期岩浆活动的缩影。从钾长花岗岩墙－文峪第一次侵入体－文峪第二次侵入体，岩石向相对基性度增高方向变化，可能暗示区域岩石圈的热－物质调整从印支期至燕山早期持续增强。     

中强震与江苏新沂地震台地电阻率异常的关系研究

运用速率法、滑动富氏法对江苏省新沂地震台1990年至1999年地电阻率观测资料进行了分析，研究了电阻率异常与江苏省及其邻近地区的中强震的关系。结果表明．从1994年到1997年之间发生的中强震，新沂地震台地电阻率3个测向有不同程度的异常与之对应。研究结果表明．资料异常呈现出的各向异性和其对应性与地球自转加速年份、孕震期的应力状态、震区构造、介质结栖有关。

INTERANNUAL VARIATIONS OF ATMOSPHERIC HEAT SOURCES AND MOISTURE SINKS OVER THE EQUATORIAL PACIFIC AND THEIR RELATIONS TO THE SST ANOMALIES

The interannual variations of atmospheric heat sources and moisture sinks over the Equatorial Pacific and their relations with the SST anomalies are studied using ECMWF reanalysis data from 1979 to 1993. It is found by singular value decomposition (SVD)…     

CHARACTERISTICS OF ATMOSPHERIC HEAT SOURCE ASSOCIATED WITH THE SUMMER MONSOON ONSET OVER THE SOUTH CHINA SEA AND THE POSSIBLE MECHANISM RESPONSIBLE FOR ITS LATE OR EARLY ONSET

The characteristics of atmospheric heat source associated with the summer monsoon onset in the South China Sea (SCS) are studied using ECMWF reanalysis data from 1979 to 1993. A criterion of the SCS summer monsoon onset is defined by the atmospheric hea…     

Parameters of Land-Surface Processes for Gobi in North-West China

Using data from the intensive observation period (May–June 2000) of the NWC-ALIEX (The Field Experiment on Interaction between Land and Atmosphere in Arid Region of North-west China), the characteristics and mechanisms of some key land-surface process over Gobi in a typical arid region of north-west China are analyzed and several parameters of land-surface processes are calculated. The weighted mean of the surface albedo over a typical arid region of the Dunhuang Gobi is calculated using the relative reflection as a weighting factor, and its value is 0.255 ± 0.021. After removing the influence of precipitation, the mean soil heat capacity over a typical arid region of the Dunhuang Gobi is 1.12 × 10⁶ J m^-3 K^-1,which is smaller than that observed in the Heihe (China) River basin Field Experiment (HEIFE). The mean soil heat diffusivity and conductivity are about half of those observed in HEIFE.
