注釋

Perhaps the tradition of carrying the bride over the threshold is dying out, but knowledge of the custom persists, leading one to wonder about the -hold or the thresh- in the word threshold. Scholars are still wondering about the last part of the word, but the thresh- can be explained. It is related to the word thresh, which refers to an agricultural process. This process of beating the stems and husks of grain or cereal plants to separate the grain or seeds from the straw was at one time done with the feet of oxen or human beings. Thus, the Germanic word .therskan, or by the switching of sounds called metathesis, .threskan, meant “thresh” and “tread.” This association with the feet is probably retained in Old English therscold or threscold (Modern English threshold ), “sill of a door (over which one treads).”

或許抱新娘過門檻的傳統(tǒng)已過時，但這種習(xí)俗仍為人所知，使人想到threshold 中的 -hlod 或 thresh- 。 學(xué)者們?nèi)圆磺宄@個詞的后半部分，但thresh- 已可作解釋。 它與指一種農(nóng)業(yè)加工的thresh 一詞有關(guān)。 這種通過打谷子或谷類植物的莖殼以使各粒與莖管分開的作業(yè)曾一度是用?；蛉说哪_來做的。因此，德語詞therskan 或經(jīng)音位轉(zhuǎn)換后的 threskan 表示“打”和“踩踏”。 這種和腳的聯(lián)系可能在古英語therscold 或 threscold （現(xiàn)代英語 threshold ）中仍保留著， “門檻（踏過的地方）”

threshold

閾(值)；［定限，臨限］

1. A logic operator having the property that if P is a statement, Q is a statement, R is a statement, …, then the threshold of P, Q, R, … is true if at least N statements are true, false if less than N statements are true, where N is a specified nonnegative integer called the threshold condition.

一種邏輯運算符，它有這樣的特性：如果P，Q，R，…都是命題，那么若至少有N個命題是真，則P，Q，R， …的閾值為真；若小于N個命題是真，則P，Q，R，…的閾值為假。其中N是指定的非負(fù)整數(shù)(稱之為閾條件)。 2. The threshold condition as in 1. | 閾條件，如1.所述。 參閱fault threshold, faultrate threshold。
