【正文】 責任；債務(wù)；傾向；可能性；不利因素liability表示“責任”類的意思時，指的是需要對某事負責任，尤其指法律上對于還款、賠償?shù)鹊呢熑位蛄x務(wù)，多與金錢相關(guān)。liability的復數(shù)形式“l(fā)iabilities”表示“負債，債務(wù)”，是術(shù)語。The car doesn39。t belong to me, but I have legal liability for any damage I caused to it. 雖然這輛車不是我的，但是我對其已造成的任何損壞都是需要負法律責任的。6. function n. 功能；函數(shù)；職責；盛大的集會 v. 運行；活動；行使職責function也有表示“職責”的意思，它主要指的是工作方面的，與職業(yè)或職位相關(guān)的職責。perform a function 履行職責It is necessary to teach them the importance of performing their functions. 有必要讓他們明白履行自己職責的重要性。7. incumbency n. 義務(wù)；任職；責任incumbency有“任職；任期”的意思，所表示的“責任”類的意思主要指公職或官職方面的，尤其指政治職位。Dan is extremely interested in politics, so he decides to conduct a study about incumbency advantage. 丹對于政治極其感興趣，所以他決定進行一個關(guān)于在職優(yōu)勢的研究。英語中有些近義詞的區(qū)別是很微妙的，所以區(qū)分它們最好的辦法就是通過閱讀、寫作等實踐方式，結(jié)合語境進行理解。馬了這么多單詞，要實踐運用起來才行哦。(Accuracy)與精密度(Precision)的區(qū)別In the fields ofengineering,industryandstatistics, theaccuracyof ameasurementsystem is the degree of closeness of measurements of aquantityto its actual (true)value. Theprecisionof a measurement system, also calledreproducibilityorrepeatability, is the degree to which repeated measurements under unchanged conditions show the sameresults.[1]Although the two words can besynonymousincolloquialuse, they are deliberately contrasted in the context of thescientific method.Accuracy準確度 is the difference between the measured value and the true value of a tested material.Precision精確度 is the repeatability of successive measurements under the same conditions.測量的精密度、準確度和精確度這是人們在測量中常常容易混淆的三個名詞，雖然它們都是評價測量結(jié)果好壞的，但涵義有較大的差別。 1．測量的精密度高，是指偶然誤差較小，這時測量數(shù)據(jù)比較集中，但系統(tǒng)誤差的大小并不明確?！ ?．測量的準確度高，是指系統(tǒng)誤差較小，這時測量數(shù)據(jù)的平均值偏離真值較少，但數(shù)據(jù)分散的情況，即偶然誤差的大小不明確?！ ?．測量精確度（也常簡稱精度）高，是指偶然誤差與系統(tǒng)誤差都比較小，這時測量數(shù)據(jù)比較集中在真值附近。AccuracyAccuracy ishow close a measured value is to the actual (true) value.PrecisionPrecision ishow close the measured values are to each other.準確度（Accuracy）：指在一定實驗條件下多次測定的平均值與真值相符合的程度，以誤差來表示。它用來表示系統(tǒng)誤差的大小。精密度（Precision）：是指多次重復測定同一量時各測定值之間彼此相符合的程度。表征測定過程中隨機誤差的大小。（精密度高是指重復性好repeatability，描述儀器本身的性能用precision；最對比實驗得到的結(jié)果用準確度accuracy，對比儀器的值可看作真值；一般實驗結(jié)果給出的是標準偏差standard deviation，用不確定度uncertainty表示）精確度=準確度+精密度可用下圖表示：Accuracy and precision in binary classificationAccuracy is also used as a statistical measure of how well a binary classification test correctly identifies or excludes a condition.That is,the accuracy is theproportionof true results (both true positives and true negatives) in the population. It is a parameter of the testOn the other hand, precision is defined asthe proportion of the true positives against all the positive results (both true positives and false positives)10
