Evaluation of solar temperature field under different wind speeds for Shanghai 65 m radio telescope

The Shanghai 65 m radio telescope is currently the largest full range rotatable radio telescope in Asia. Gravity, wind and temperature are the three main factors which may have a bad effect on the reflector’s surface precision. To study the effect of the thermal deformation caused by daily non-uniform temperature fields on the surface precision of the main reflector, both the temperature field and its effect were studied in detail for two typical days (January 15th and July 15th). The method to simulate temperature fields was studied initially, considering heat conduction, solar radiation, shadowing, air convection, sky radiation and ground radiation. Then, an integral parametric thermal finite element model (FEM) of the telescope was established using the ANSYS thermal analysis module. Finally, the effect of non-uniform temperature fields on the surface precision of the main reflector was estimated in terms of the Root Mean Square (RMS) deformation based on temperature transient analysis. The proposed methods and conclusions drawn can provide valuable information for thermal design, thermal monitoring and thermal control of the Shanghai 65 m radio telescope and other similar giant antenna structures.     

Planning for Health: Complexity of Environmental Health and Planning Responses

China's rapid urbanization has led to increasing environmental health problems, which poses great challenges to urban sustainable development. In order to explore the scientific issue of planning for health, this paper firstly analyzes the challenges of spatial planning caused by environmental complexity in terms of health risk, environmental impact, and residents' behavior. And then it puts forward an analytic framework that includes three basic modules, i.e., theoretical model, regional health risk identification, and planning performance assessment, thereby finally proposing six spatial planning strategies according to the objectives of health protection, health promotion, and health equity, on the basis of the actual situation of health risk exposure, environmental friendliness, and the aging level in different cities of China.

内蒙古某银锌矿选矿试验研究（增刊）

内蒙古某银锌矿为含低品位铅锌的硫化银矿石,其中银品位为151.1g/t, 铅、锌品位分别为0.27%和0.56%,硫含量为1.30%,鉴于矿石中铅品位比较低,难以单独富集为铅精矿,采用原矿优先选银（铅）-选银（铅）尾矿锌硫混选-锌硫分离工艺进行试验,最终可以获得银品位为9848.81g/t、铅品位为17.41%,银、铅回收率分别为85.40%和88.46%的银精矿,其中锌含量为4.00%、硫含量为34.77%;可以获得锌品位50.95%,锌回收率为66.71%的锌精矿,其中银、铅和硫的含量分别为801.41g/t、0.44%和33.25%。试验指标比较理想。
