Verification scheme of measuring instruments for neutron source strength 中子源強度計量器具檢定系統(tǒng)
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 求解過程中待求的空泡源強始終布置在槳葉表面上,而在根據(jù)動力學條件求解每一步的空泡面元偶極子強度時,積分是沿著上一步迭代確定的空泡表面進行的。
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 摘要通過對近年來國內(nèi)城市軌道交通環(huán)境影響評價實例的回顧,在對環(huán)境評價結果與實際效果進行分析和總結的基礎上,對環(huán)境影響評價中的若干問題進行綜合探討,包括環(huán)境保護目標的選擇、源強類比的準確性、噪聲與振動預測方法及采取控制措施的原則等。
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 根據(jù)水運化學品泄漏事故的具體實際,針對各種泄漏物質、泄漏源和環(huán)境條件研究了各自適用的擴散模式和源強計算模型,以便通過擴散模擬確定事故的毒害和火災爆炸危險區(qū)域;為解決儲罐泄漏量計算困難的實際問題,推導了適用各型儲罐、液艙的泄漏量計算公式;針對化學品水路儲運泄漏事故中泄漏物質可能會以混合物形式存在的情況,探討了混合物的蒸氣釋放源強計算;為方便實用,開發(fā)了蒸氣擴散危險區(qū)域模擬計算機軟件,從而為事故應急決策提供了有力的輔助支持,以達到盡可能減少人員傷亡和財產(chǎn)損失,減輕環(huán)境污染的目標。
