一种模拟动力学边界条件的环境振动试验方法研究

目的提高环境振动试验的可靠性。方法以某典型钛合金蜂窝夹芯壁板试验件为例,提出一种模拟试验件动力学边界条件的试验方法,在试验件周围引入弹性连接件,再通过刚性转接工装与振动台台面连接,以试验件在试验安装状态下的共振频率及振型节线位置为优化目标,以弹性连接件的外形尺寸及厚度为优化变量,对弹性连接件进行优化设计,从而模拟试验件真实的动力学边界条件。结果弹性连接件的优化设计使得试验件在试验安装状态下前两阶共振频率与试验要求相差小于8%,而且振型节线位置与试验要求基本重合,达到了模拟试验件真实动力学边界条件的设计目标。结论对于壁板类试验件,在传统刚性夹具的基础上引入弹性连接件的试验方法,可以较好地模拟试验件真实动力学边界条件,提高环境振动试验的可靠性,并且这种方法对试验费用及试验周期影响较小,具有良好的工程应用前景。     

重度雾霾环境下篮球运动对人体心肺机能的影响研究

雾霾一直是影响人体健康的始作俑者之一,重度雾霾环境下人体的各项机能均会下降,甚至衰竭。针对重度雾霾环境下篮球运动对人体心肺机能的影响开展下列研究:对雾霾天气形成因素进行详细研究,经研究发现在城市中,有毒的颗粒物主要来源于汽车尾气、北方抵御冬季供暖生成的废气、工业生产中排放的气体、建筑工地与马路交通生成的扬尘等方面,特别是在长三角和珠三角地区,每年出现雾霾的天数要在100天以上,且个别城市超过了200天;将雾霾环境下篮球运动对人体心肺机能的影响划分为:易导致呼吸道及肺组织交叉感染、易导致慢性阻塞性的肺部疾病、易导致肺癌三大模块,并对形成的原因进行详细阐述。     

Black cherry growth response to ambient ozone and EDU

Field-grown black cherry (Prunus serotina Ehrh.) seedlings were treated with the antioxidant ethylenediurea (EDU) to evaluate height, diameter, and above-ground dry-weight biomass growth response to ambient ozone over four years. Nine blocks with 44 trees/block were used in a randomized complete block design with three foliar spray treatments: (1) 1000 ppm EDU mixed with a surfactant and water; (2) surfactant mixed with water; and (3) water only. In each growing season treatments were applied seven times at approximately 10-day intervals. Repeated measures analysis of variance indicated significant (P< or =0.05) treatment and year effects for log-transformed height and diameter growth over the four-year period. After four years, EDU-treated trees were approximately 17% taller and stem diameters were 21% greater than non-EDU-treated trees. Total above-ground dry-weight biomass at the end of four years was 47% greater for EDU-treated trees compared to non-EDU-treated trees.

含酚废水治理方法的研究

根据含酚废水的性质，用ClO2氧化除酚，ZL—1和聚丙烯酰胺(PAM)混凝沉降除悬浮物的方法处理该废水。实验结果表明，经处理后废水中的主要污染物酚、焦油和悬浮物等去除率都很高，该水可以满足循环使用的要求。     

A regional environmental management information system for Chinese EPA—the system analysis and design

REMIS is one of key research projects sponsored by the central government. It is recommended to regional EPAs as a main tool of the environmental management. REMIS simulates the functions of the regional EPAs and aimed to improve their management level. The national environmental management information system will base on REMIS.Functional analysis is the kernel of the REMIS system analysis. Data and data flow analysis are used to support the functional analysis.Investigations on the functions of the local EPAs of eight provinces and 12 cities have been taken. The functions were carefully sorted. Modular design method was used in system analysis and system design.The system analysis included functional analysis, data analysis and data flow analysis. The system design is based on the system analysis. HIPO diagram of each modular, data base structure, menu design, selection of hardware and software environment were the main items of the system design.     

西宁盐碱地区高速公路植被恢复技术探讨

西宁至马场垣高速公路穿越的地区属于生态脆弱带。与其他生态脆弱区不同的是，其土壤中盐分的含量非常高，土壤碱性强，它不仅导致植物的生理干旱，还对植物细胞产生毒害作用，不良的植被恢复措施也加重其危害程度。为减轻盐碱的危害需要采取相应的措施如筛选适宜植物、农业灌溉、化学及其它措施，可以减轻危害恢复植被。
