Verification scheme of measuring instruments for neutron source strength 中子源强度计量器具检定系统
The unknown source strength of cavitation is always arranged on the propeller blade surface in the solving process , but the integration is carried out along the cavity surface of last iterative step when the strength of cavitation dipole is determined according to dynamic condition 求解过程中待求的空泡源强始终布置在桨叶表面上,而在根据动力学条件求解每一步的空泡面元偶极子强度时,积分是沿着上一步迭代确定的空泡表面进行的。
By reviewing the cases of environment impact value of urban rail transit in china in recent years , and based on the analysis and summary of environment impact value ( eiv ) results and practical effects , some problems in environment impact value ( eiv ) are discussed comprehensively , among which arc the choice of environment protection targets , the accuracy of source strength analogy , forecasting methods of noise and vibration and the principles of control measure 摘要通过对近年来国内城市轨道交通环境影响评价实例的回顾,在对环境评价结果与实际效果进行分析和总结的基础上,对环境影响评价中的若干问题进行综合探讨,包括环境保护目标的选择、源强类比的准确性、噪声与振动预测方法及采取控制措施的原则等。
According to the facts of chemical spill accidents in waterway transport , systematic analysis is made on the suitable dispersion models and source strength calculation models of multiple spilled substance , resource and environment respectively , so as to decide the poison and fire & explosion danger area of an accident through the way of dispersion simulation . to resolve the problem to the calculation of spill amount from tanks , calculation formulas on various types of tanks were worked out ; at the same time , research is carried out on the source strength calculation of mixtures with regard to the possible spillage of chemical mixture in waterway transport . for the sake of convenient application , a computer software for the simulation of dangerous area is developed which can provide great assistance to the decision - making of emergency response and reach the target of reducing the damage of the life , property and environment to the smallest degree 根据水运化学品泄漏事故的具体实际,针对各种泄漏物质、泄漏源和环境条件研究了各自适用的扩散模式和源强计算模型,以便通过扩散模拟确定事故的毒害和火灾爆炸危险区域;为解决储罐泄漏量计算困难的实际问题,推导了适用各型储罐、液舱的泄漏量计算公式;针对化学品水路储运泄漏事故中泄漏物质可能会以混合物形式存在的情况,探讨了混合物的蒸气释放源强计算;为方便实用,开发了蒸气扩散危险区域模拟计算机软件,从而为事故应急决策提供了有力的辅助支持,以达到尽可能减少人员伤亡和财产损失,减轻环境污染的目标。
