(3) Proposed four kinds of conditions influence landslide hazard: the geologicalfunction condition, the river erosion function condition, the terrain influence condition,as well as the humanity activity condition.
With the development of computers, numerical simulation technology is widely applied in the industry. In the paper, 3 dimensional designing software Solidworks is used for generating the model and CFD simulation software FLUENT is used for the simulation of the combustion machine. Through comparing with the simulation results, the relations of the distribution with the flow field and relevant influence condition are obtained and the theoretic basis is provided for the successive multiphase flow and combustion condition.
Influences of squeeze casting temperature on interface reaction of K 2O·6TiO 2(W) /ZA27 alloy composites had been analyzed and discussed. The growing mechanism and the condition of interface reaction between K 2O·6TiO 2 whisker and ZA27 matrix alloy was proposed.
分析讨论了挤压铸造温度对K2 O·6TiO2 (W ) /ZA2 7合金复合材料界面反应的影响条件 ,并提出了复合材料界面反应产生条件和生长机制
A method for the indirect determination of Cl- and SO42- by ICP-AES is developed. The method is realized by determining surplus Ag- and Ba2- after adding excessive Ag+ and Ba2+ and precipitating AgCl and BaSO4. The lowest detectable concentration for Cl- and SO42- was 1. 2 and 1. 4μg/ml. respectively.
This report mainly discussed design problems of reentry maneuvering trajectories. Technique method of selecting Lift-to-drag ratio of reentry maneuvering trajectories was attained under the condition of velocity of falling on the ground being maximum value and of considering effect of angle of attack to drag coefficent.
