Strategic Study of CAE 2007, Volume 9, Issue 11, Pages 120-126

Abstract:

Through the research of the water-salt movement under different groundthe symptom of redistribution of water and salt in certain area:when the evolvement of water and salt movementoccurs in vertical and horizontal direction, there is also the important symptom of sideward movementabroad, and discusses the new mode of salt drainage under both the condition of water-salt directional movementand the condition of salt movement to the earth's surface.

Cell-Zone Method: An Engineering Approach to Predict Smoke Movement in Large Scale Building Fire

Hu Longhua,Huo Ran,Liy Uanzhou,Wang Haobo

Strategic Study of CAE 2003, Volume 5, Issue 8, Pages 59-63

Abstract:

In large scale building fire, it is improper to predict smoke descending using traditional simple two-layer zone model, which divides the total space of the building into upper hot smoke layer and lower cool air layer. In this paper, an improved method, named Cell-Zone Method, is used to solve this problem, which first divides the total space into some small subspaces and then uses traditional two-layer zone model in each subspace. Comparison is carried out between these two methods in fire smoke development simulation in typical large space buildings by CFAST4.02 software package. Results show that Cell-Zone Method demonstrates more applicability than traditional simple two-layer zone model in large scale building, especially in buildings having large scale in one direction.

The study of HY-2A satellite engineering development and in-orbit movement

Zhang Qingjun,Zhang Jian,Zhang Huan,Wang Rui, Jia Hong

Strategic Study of CAE 2013, Volume 15, Issue 7, Pages 12-18

Abstract:

HY-2A is China's first ocean dynamic environment satellite, and it is currently the only one satellite which is capable of all-weather, all-day synchronous access to the global sea surface altitude, available wave altitude, sea wind field, sea surface temperature, atmospheric water vapor, cloud liquid water and other remote sensing data. HY-2A satellite equips four kinds of active and passive microwave remote sensing load, adopts a new remote sensing system, realizes the localization of key parts and has certain characteristics of precision orbit determination, electromagnetic compatibility and high precision attitude control. As the first comprehensive type microwave remote sensing satellite, the realization of HY-2A engineering is significant. This paper is introduced about the aspects of system composition and functions, development stage, large-scale test, in-orbit test and application results show.
