The summation extends over all the ions in the solution . 總和包括溶液中所有的離子。
It is convenient to introduce here the summation operator . 應(yīng)當(dāng)在此介紹一下求和的算符。
The summation of forces in this and that directions must be zero . 在這個(gè)和那個(gè)方向上的合力必定為零。
the summation is over all molecular states for which ≠0. 求和手續(xù)遍及于0的所有分子態(tài)。
The integral of the tabulated function can be found by forming a summation series . 表列函數(shù)的積分可用列出和的系列求出。
The electrostatic summation must be evaluated for an explicit set of ion position . 靜電能的加和必須根據(jù)離子的具體位置來(lái)計(jì)算。
The summation forms are quite convenient for computation, especially when the interval is kept constant . 和式形式是十分有利于計(jì)算的,特別是當(dāng)間隔保持常值的時(shí)候更是如此。
Summations are almost invariably indicated ellipses instead of the more prevalent sigma notation . 在表示“連加”的式子中,幾乎一成不變地使用省略號(hào)來(lái)代替更為流行的“”符號(hào)。
A pair of drums is used, and the signals are transformed successively from one to the other as the summation proceeds . 采用雙鼓,信號(hào)不斷從一個(gè)鼓傳遞到另一個(gè)鼓就如相加的過(guò)程。
If we wish to check the structure for a significant number of hypotheses, the use of a small computer facilitates the extensive summation processes . 如果要計(jì)算未知數(shù)很多的結(jié)構(gòu),使用小型計(jì)算機(jī)能使大量求和過(guò)程更簡(jiǎn)便。
the arithmetic operation of summing; calculating the sum of two or more numbers; "the summation of four and three gives seven"; "four plus three equals seven" 同義詞:addition, plus,

Summation is the operation of adding a sequence of numbers; the result is their sum or total. If numbers are added sequentially from left to right, any intermediate result is a partial sum, prefix sum, or running total of the summation.
