probability n. 1.或有;或然性。 2.【哲学】盖然性〔在 certainly 和 doubt 或 posibility 之间〕。 3.【数学】几率,概率,或然率。 4.或有的事;可能的结果。 5.〔pl.〕〔美俚〕天气预测。 What are the probabilities 有几分把握? The probabilities are against us [in our favour]. 趋势对我们好像不利[有利]。 hit probability 命中率。 in all probability 很可能,大概,多半,十之八九。 probability of (missile survival) (飞弹不被击落的)概率。 The probability is that ... 大概是…,很可能是…。 There is every probability of [that] ... 多半有,多半会。 There is no probability of [that] ... 很难有,很难会。
theory n. 1.理论,学理,原理。 2.学说,论说 (opp. hypothesis)。 3.推测,揣度。 4.〔口语〕见解,意见。 the theory of two points 两点论。 Darwin's theory of evolution 达尔文的进化论。 theory of equations 【数学】方程论。 theory of everything 【物理学】(把相对论、量子论和宇宙大爆炸理论都包括在内的)万用理论。 theory of relativity 【物理学】相对论。 the atomic theory 原子说。 Our scheme is good both in theory and in practice. 我们的方案在理论上和实施上都是好的。 combine [separate] theory with [from] practice 理论结合[脱离]实际。 My theory is that we must bring new blood into the Institute through appointment of younger men to important positions. 我的意见是我们学院应该通过重用年轻一些的人来注入新的血液。 theory of games 博弈论,对策论,权衡利弊得失的形势分析。
Secondly , the load action theory probability model of beam - bridge is researched in this dissertation , and also the load action effect theory probability model 其次,研究梁桥荷载作用及作用效应理论概率模型。
Thirdly , the structure resistance theory probability model and the load action effect theory probability model are amended according to the main - beam ' s damage and load condition of the used beam - bridge . thus the structure resistance assessment probability model and the load action effect assessment probability model of the used beam - bridge are deduced in this way and they are practical 再次,根据在用梁桥的损伤情况和荷载状况,对其结构抗力和荷载效应理论概率模型进行修正,得到实用的在用梁桥结构抗力和荷载效应评估概率模型。
