COMPILATION OF HEAT FLOW DATA IN THE CHINA CONTINENTAL AREA (2nd Edition

During the last 2 years, heat flow data increased significantly in China as a result of implementation of many comprehensive geodynamic (including geothermal) projects and GGT project in China. In this paper, a total of 366 reliable heat flow data is collected from published and in press sources in the Compi-ilation of Heat Flow Data in the China Continental Area (2nd edition). Statistic analysis of these data shows that the heat flow values in China continental area vary from 20 to 14...     

FLUVIAL PROCESSES IN THE LOWER YELLOW RIVER AFTER LEVEE BREACHING AT TONGWAXIANG IN 1855

I. CHAncEL CHANGal m THE FLOODED AREA ArVER BREACHING AT TONGWAXIANG AND THEIR IMPACTSIn mid--June of 1855 a great flood occurred in the lower reaches of the Yellow River. The findmainly came down from the main stem of the river and itS tributary Qinhe River. In the meantimethe riparian area of the Yellow River had just been subjected to a heavy rain, and large amountS of water from mountains and hills were flowing into the river and lakes were also full.

NUMERICAL SIMULATION OF TROPICAL CYCLONE MOVEMENT WITH THE RELATED CRITICAL POINT PHENOMENON

A study is made of the paths of tropical cyclones under the joint action of environmental flow and heating fields interms of a quasi-geostrophic barotropic model with the thermal forcing and dissipation terms involved,in which 16 ex-periments are designed and integrated for more than 7 model days.Results show that for different parameter values ofthe environmental flow and heating field,and the cyclone scale, such paths as counterclockwise looping, zigzag form andwestward march with an abrupt turning towards the north are reproduced clearly in the model atmosphere,exhibitingtheir critical points of nonlinear character.     

SPECTRAL CHARACTERISTICS OF SURFACE-LAYER TURBULENCE OVER THE SUBURBS OF TIANJIN

The paper computed the spectra of velocity and temperature,and the cospectra of velocity and temperature by theobservational data of July,1990 in the suburbs of Tianjin.The results show that the characteristics of the atmosphericturbulence spectra over the suburbs are basically in accordance with some typical results over the flat terrain.But thescale,on which turbulence can satisfy the isotropic condition,over the suburbs is larger than over the flat terrain.Thespectrum peak frequency range is a bit narrower.The feature of the spectrum range in low frequency(LF)is out ofaccordance with that of the flat terrain either.

变质流体的溶液化学

变质流体中载有重要的溶解物质，这些溶解物不但在交代作用过程中起着重要作用，而且还影响着固相平衡。岩石中的某些组分（如氧化硅），虽溶于水但却不能形成络合物，即便在有附加配位体的情况下也是如此。大多数阳离子的浓度主要取决于络合配位体的有效性。尽管氯化物是配位体中最重要的成员，但对某些金属而言，那些较次要的配位体却更为有效。
