occurrence probability meaning in English
产状概率
出现几率
Examples
- Exceptional load cases are those corresponding to events of very low occurrence probability requiring the safe shutdown and inspection of the vessel or plant
异常负荷案例是相对很少发生的事件，要求安全关停和容器设备的检查。 - The occurrence probability and existence form of internal defects in rolled pieces during three - roll and two - roll cross wedge rolling were compared and analyzed by finite element numerical simulation
摘要采用有限元数值模拟方法，比较分析了三辊楔横轧与两辊楔横轧轧件内部缺陷的产生几率和存在形式。 - In china , because the grade crossing is master in urban road traffic , the occurrence probability of side impact accident is highest , its death rate is only next to front impact ’ s death rate , but the injury rate is first
在我国,由于城市道路交通路口以平面交叉形式为主,侧面碰撞事故发生概率最高,其致死率仅次于正面碰撞,而致伤率却居第一位。 - Spatial distribution and time scales of atmospheric diffusion over beijing area are revealed by means of a random walk simulation model and practical meteorological data with a specified emission source from the city . results show a southward transport pattern for wintertime while a northwest transport of pollutants in summer . the area is the least evidently influenced by the emission source in spring , while the largest in autumn . the time spent for instantly emitted material removing from the model domain varies from winter - spring to summer - autumn . the former was shorter one of less than 20 hours ; the latter was longer one of approximately 30 hours . distribution of occurrence probability for different removal times was not symmetry . reducing slowly at the end of longer removal time , probability exists for pollutants remaining in this area a long time
结果表明，冬季示踪物偏南夏季偏西北的输送明显春季扩散影响范围最小秋季最大。示踪物从200km200km模式区域输出的平均时间去除时间明显分为冬春季和夏秋季两组，前者较小，平均在20h以下，后者较大，平均约30h 。不同去除时间出现的频率分布是非对称的，在长去除时间一侧，出现频率下降缓慢，显示污染物有在该区域内长时间滞留的可能。 - Based on the calculation of shearing - slipping failure probability of high arch dams , the calculation method and procedures are presented by use of the second moment method for calculation of the occurrence probability of the major failure modes of high arch dams , and the relation degree between the major failure modes and the failure probability with multi - failure modes of the high arch dam are calculated
以计算高拱坝剪滑溃坝发生概率为例，说明利用二阶矩法计算高拱坝各主要失效模式发生概率的步骤，进而求解各失效模式的相关程度及具有多个失效模式高拱坝的失效概率。
