Any of a group of five chemically related nonmetallic elements including fluorine, chlorine, bromine, iodine, and astatine.

酰亚胺源自氨的一种化合物,含有与一个二价酸基或者二个一价的酸基结合的氨基

The compound is an ionic compound consisting of a cation NH(subscript 4 superscript +) and an anion C6H2N3O(subscript 9 superscript -), and it is the mono-substituted salt of TNPG. Since the existence of complicated hydrogen bond networks and electrostatic attraction between NH(subscript 4 superscript +) cation and C6H2N3O(subscript 9 superscript -) canion, the compound possesses better stability and low sensitivity.

该化合物是由一个铵根离子与一个一价的三硝基均苯三酚负离子相结合而形成的离子型化合物,分子中存在的大量氢键及铵根离子与三硝基均苯三酚负离子之间的静电引力使得该化合物具有较高的热稳定性和较低的感度。

The result showed that the one-valence cationsaccelerate the hydration process of α-hemihydrate gypsum greatly because they improvethe dispersed degree of α-hemihydrate gypsum particles due to the remarkable effect ofincreasing theζpotential; the effects of bivalent and trivalent cations on ζpotentialdecrease in turn, compared with monovalent cations, the effects on both the disperseddegree of α-hemihydrate gypsum particles and the setting time of paste are little.

研究还表明:由于一价阳离子能较大程度地提高石膏浆体的ζ电位,因而有效地提高了石膏颗粒的分散程度,对α半水石膏的水化加速作用很大,而二、三价离子对石膏浆体的ζ电位影响依次减小,对半水石膏颗粒的分散程度和浆体凝结时间的影响均不如一价阳离子作用大。

A salt or an ester of malic acid.

硝酸根,硝酸盐一价的根NO3或包含它的化合物,如一种硝酸盐或者酯

Halogen atoms contain seven electrons in their valence shell, and, consequently, are monovalent

卤原子在它们的价电子层含有七个电子,因此是一价的

一价的在酸碱反应中只有一个氢离子转移到碱上的;一碱价的

For two possible geometric structures,square and regular tetrahedron,the electronic structures of ground state and structure parameters of the O_4,O-_4 and O+_4 are calculated according to the principle of minimum energy.

计算了2种可能的空间结构——正方形和正四面体,分别得到了这2种结构的中性分子O4,正一价分子O+4和负一价分子O-4的基态电子结构,并根据能量最低原则确定了各自的结构参数,从而得到了O4分子2种结构的基态总能量、一价电离能及电子亲合势能。

The univalent radical NO 3 or a compound containing it, as a salt or an ester of nitric acid.

硝酸根,硝酸盐:一价的根NO 3或包含它的化合物,如一种硝酸盐或者酯

The univalent radical NO3or a compound containing it,as a salt or an ester of nitric acid.

硝酸根,硝酸盐一价的根NO3或包含它的化合物,如一种硝酸盐或者酯

However, there is no such restriction on the transformational forms, such as the Dative Construction in English and the sentence marked by "ba" in Chinese. The differences are: Chinese DOC has a more wide-ranging scope; Some verbs used in the Chinese DOC sentences are inherently one or two-place, but verbs used in the English DOC is at least inherently two-place, can't be one-place; some verbs bearing the same meaning can construct a DOC sentence in Chinese but not in English, and vice versa; there are differences on the form, the position and the ellipsis of the double objects; there are differences on the passive form of the DOC in both languages.

其不同点有:汉语的双宾结构范围更广;汉语中有的动词可能是一价或二价,但英语中的动词起码是二价,不可能是一价;有些具有相同意思的动词在汉语中可以构成双宾结构,在英语中则不能;反之亦然;在英汉语中,间接宾语和直接宾语的构成、省略及位置上都存在差异;英汉语的双宾结构的被动式形式存在差异。
