ionic adj. 愛奧尼亞的,愛奧尼亞人的;愛奧尼亞音步的;【建筑】愛奧尼亞式的。 Ionic capital 愛奧尼亞式的柱頂。 n. 愛奧尼亞語(yǔ);〔i-〕 【印刷】一種粗字面鉛字。 adj. 離子的。 ionic bond [link] 【化學(xué)】離子鍵。 n. -ity 離子性,電離度。
An ionic bond is characterized by the transfer of an electron from one atom to the other . 離子鍵的特點(diǎn)是一個(gè)電子可以從一個(gè)原子轉(zhuǎn)移到另一個(gè)原子。
Ceramics primarily have ionic bonds , but covalent bonding is also present 陶瓷初始狀態(tài)是受離子束縛的,但是還是有共價(jià)鍵結(jié)構(gòu)的。
The chains are held together by ionic bonds , whereas individual silica tetrahedrals bond together covalently 這些鏈狀四面體組織由離子鍵束縛,而一個(gè)個(gè)單獨(dú)的硅四面體卻以共價(jià)鍵結(jié)合在一起。
In recent years researchers have achieved better performance with compounds such as lithium borohydride , in which the metal atoms form weaker , ionic bonds with groups containing several hydrogen atoms 近年來(lái),研究人員已經(jīng)制作出效能更佳的復(fù)合物,例如硼氫化鋰,在這種金屬氫化物中,金屬原子與氫原子團(tuán)(由數(shù)個(gè)氫原子組成)之間,是以較弱的離子鍵鍵結(jié)。
Montmorillonite ( mmt ) clay is an important class of lamellar inorganic compounds , contains negatively charged layered silicates , which are bonded with metal cations such as na + or ca2 + by ionic bonding . whose interlayer spacing can be modified by cation exchange . when the mmt is exchanged with cations , its inner layer spacing becomes large enough to be penetrated by a monomer 蒙脫土( montmorillonite , mmt )是一種天然礦物,具有層狀結(jié)構(gòu),層間靠吸附陽(yáng)離子如na ~ + 、 ca ~ ( 2 + ) 、 mg ~ ( 2 + )等來(lái)維持電荷平衡,這些離子可與其它陽(yáng)離子進(jìn)行交換,使有機(jī)單體分子進(jìn)入層間,聚合后即可形成有機(jī)無(wú)機(jī)納米復(fù)合材料。
