The two stresses can then be added algebraically to obtain the resultant . 然后將兩種應(yīng)力代數(shù)相加就得到合應(yīng)力。
This can be done numerically by computer or algebraically as follows . 這可借計(jì)算機(jī)用數(shù)值去完成或像下面那樣用代數(shù)來(lái)完成。
First interpret it combinatorially, and then derive it algebraically from the multinomial theorem . 先用組合方法闡述,然后從多項(xiàng)式定理利用代數(shù)方法推導(dǎo)。
It is much easier to indicate how to find the mean by expressing the procedure algebraically . 用代數(shù)的方法來(lái)表現(xiàn)這個(gè)過(guò)程,就更容易說(shuō)明平均數(shù)是如何求得的。
Algebraically independent elements 代數(shù)無(wú)關(guān)元素
