“70后”再解读

通过青春境遇、成长之痛、回归本身、内部流变这四个部分对“70后”作家的生存与书写进行了评析，对这样一种创作现象做一个总体的、公允的价值判断。     

原子簇在熔体晶体生长中的作用

原子簇在熔体晶体生长中的作用蔡英文，范新会，李建国，傅恒志原子簇是指由原子群体所构成的相对稳定的集团，也称团簇［１］。它的存在构成了凝固形核理论的核心，但在生长动力学理论中却从未有人对原子簇的作用加以思考。事实上，从高温过热工艺（ＢＴＯＰ，俄）［２］...

Development of Karst Formation in Area 4 of Tahe Oil field

The main oil-bearing formation of Area 4 of Tahe oilfield is in Yingshan Group of Ordovician consisted of thick pure limestone. The types of the pore space contain the pore, fissure, cave as well as fracture formed by solution collapse. The primary porosity and tectonic fracture are of poor growth. Therefore, the formation growth is mainly controlled by hydraulic units of the palaeo-karst. There are three palaeo-hydraulic zones: vadose zone (including infiltration sub-zone and percolation sub-zone), phreatic zone and tranquil zone. They are identified by retrieving the palaeo-geographical karst environment. The pore space of the infiltration zone is mainly solution fissures, small solution cavities and solution pores. The growth and lateral connection of the formation are favorable. The reservoir/formation ratio is 0.54. The pore space of the phreatic zone developed large size cavities and fractures related to cave collapse. The height of the cavity can reach 71m. The fractures by collapse have a influencing range of more than 100m, and its reservoir/formation ratio is 0. S1. But the lateral connection is unfavorable. The percolation subzone and the tranquil zone are of relatively poor growth with the reservoir/formation ratio less than 0.3.

Coalescence of the crystallites under hydrothermal conditions (II) —— The morphology and stability energy calculation of cuprite

The coalescence of crystallite under hydrothermal conditions was discussed in our previous paper[1]. When the solute concentration exceeds the supersaturation, the nucleation and growth process take place. The initial crystallites are only several nanometers. They have high surface-to-volume ratio, high index surfaces, and therefore have high surface energy. As the hydrothermal reactions proceed in the alkaline medium, the crystallite surfaces are apt to absorb polar solvate ions such as OH-,…     

构建我国反贫困机制问题探讨

关于贫困的研究,学术界主要是从公平、伦理、道德等角度进行的。从“贫困人口的存在构成了对经济增长的制约”这一角度出发,进行较系统的探讨。
