probability n. 1.或有;或然性。 2.【哲學(xué)】蓋然性〔在 certainly 和 doubt 或 posibility 之間〕。 3.【數(shù)學(xué)】幾率,概率,或然率。 4.或有的事;可能的結(jié)果。 5.〔pl.〕〔美俚〕天氣預(yù)測(cè)。 What are the probabilities 有幾分把握? The probabilities are against us [in our favour]. 趨勢(shì)對(duì)我們好像不利[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) (飛彈不被擊落的)概率。 The probability is that ... 大概是…,很可能是…。 There is every probability of [that] ... 多半有,多半會(huì)。 There is no probability of [that] ... 很難有,很難會(huì)。
theory n. 1.理論,學(xué)理,原理。 2.學(xué)說(shuō),論說(shuō) (opp. hypothesis)。 3.推測(cè),揣度。 4.〔口語(yǔ)〕見(jiàn)解,意見(jiàn)。 the theory of two points 兩點(diǎn)論。 Darwin's theory of evolution 達(dá)爾文的進(jìn)化論。 theory of equations 【數(shù)學(xué)】方程論。 theory of everything 【物理學(xué)】(把相對(duì)論、量子論和宇宙大爆炸理論都包括在內(nèi)的)萬(wàn)用理論。 theory of relativity 【物理學(xué)】相對(duì)論。 the atomic theory 原子說(shuō)。 Our scheme is good both in theory and in practice. 我們的方案在理論上和實(shí)施上都是好的。 combine [separate] theory with [from] practice 理論結(jié)合[脫離]實(shí)際。 My theory is that we must bring new blood into the Institute through appointment of younger men to important positions. 我的意見(jiàn)是我們學(xué)院應(yīng)該通過(guò)重用年輕一些的人來(lái)注入新的血液。 theory of games 博弈論,對(duì)策論,權(quán)衡利弊得失的形勢(shì)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,研究梁橋荷載作用及作用效應(yīng)理論概率模型。
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,根據(jù)在用梁橋的損傷情況和荷載狀況,對(duì)其結(jié)構(gòu)抗力和荷載效應(yīng)理論概率模型進(jìn)行修正,得到實(shí)用的在用梁橋結(jié)構(gòu)抗力和荷載效應(yīng)評(píng)估概率模型。
