covalence [kәu'veilәns]
n. 共用电子对数, 共价
[化] 共价
- Using the activated fibroin as carrier, the papain was immobilized using covalence-crosslinking method.
以活化丝素为载体,采用共价交联法固定木瓜蛋白酶,研究了丝素固定化木瓜蛋白酶的酶学性质. - The ability of carbon to form stable compounds in such astonnishing numbers arises in that it utilizes its four valence electrons completely in the establishment of four covalence, its valence shell becomes saturzted.
试译一下：碳能组成（着）此惊人数量的稳定的化合物在于它在四价共价健的建立中充分利用自己的四价电子，它的化学价层才能得以饱和。
