Noise control of civil boiler ventilator room usually was accomplished by dissipative muffer or sound-proofing lagging. The former fixed on the entrance of ventilator or outfall of draught fan was limited in effect, the latter cost too much. In order to drive costs down and be easy of maintenace, the author designed a bach shutter type dissipative muffer for a certain military unit. It achives the desired results

城市、矿山民用锅炉房噪声治理,通常在送风巷进口、引风机出口加消声器,或为送引风机各自设计声箱,前者降噪量有限,后者治理费用高,为降低降噪费用,便於风机的日常维护和保养。作者为太安军分区第三干休所研制、设计了金属百叶式消声器,达到了预期目的。

Based upon the natural disaster properties both in social and natural,the requirementscriterions and methods of natural disaster appraising have been explored in this paper.On thebasis of the calamity degree,an evaluation of natural disaster loss on absolute value,anotherconcept of relative value of natural disaster loss,the calamity damaged rate,has been ad-vanced.And the classified of the calamity damaged rate has been suggested.The conversionof the fixed price of the calamity loss has been discussed too. The level of the social property loss caused by the natural disaster has been scientificallyand quanitatively described by the establishment of the concepts of calamity degree and thecalamity damaged rate. The calamity damaged rate is the measure of natural disaster loss in relative.It indicatesThe ratios of the natural disaster loss to the local economy and total products.the establish-ment of the concepts both of the calamity degree and the calamity damaged rate has a greatsignificance on the hazards classification,rescue,insurance and its management.

本文从自然灾害的社会属性和自然属性出发,对自然灾害损失评估的工作准则、评估指标和方法进行了探索.在自然灾害损失绝对值度量指标——灾度的基础上,进一步提出了标度自然灾害损失的相对量指标——灾损率的概念,并建立了灾损率的等级划分标准,同时还讨论了自然灾害损失的可比价值换算问题。灾度和灾损率概念的确立,使自然灾害对社会财富的损失程度有了较为科学的、定量化的等级描述.灾度和灾损率的概念应用于灾害强度描述、救灾投入、灾害保险、减灾工作评价等方面具有重要的意义。

water tank installed at the top of tall buildings can control the seismic response of structures. In thispaper,the water tank is fixed with baffles on the inner surface of a cylindrical tank. The interaction between the water tank and the structure is considered,and the effect of the water tank on seismic responseof buildings is studied. The numerical results obtained in this paper can provide theoretical basis to designthe water tank rationally.

防晃水箱是在一般水箱内安置环形防晃板,在高层建筑顶部设置这种水箱可以对建筑物的地震反应作被动控制。本文对这一系统进行了数值模拟,考虑了水箱和结构间的相互耦合作用,研究了水箱对建筑物地震反应的影响,数值分析为合理设计水箱提供了理论依据。
