However the catalysts used for that reaction, involving their physicochemical properties, the structures and physical state, especially those under reaction conditions have not yet been investigated much or only scrappily.

虽然，各种工业用催化剂几乎均以V-K-S／SiO〓为基本成分，但配比可在较宽范围内变化，再加上引入多种助剂，更使这一体系变得更复杂，和难以深入研究。

Liquid-crystalline compounds with sulfur, reported in recent years,readily form smectic phases and exhibit broad-range mesophases.

Under the condition of laboratory incubation,the C loss of organicmaterials during their mineralization was greater than their N loss,inducing ahigher residual amount of organic organic N.During the decay of maize andrice staw with a wide ratio of C/N.soil microbes could fix N,but the fixationrate was quite low,only 0.2-0.9g N/assimulated 100g organic C.

在实验室培养条件下有机物料在矿化分解过程中C的损失总是大于N的损失，因此有机N的残留率明显高于有机C的残留；且由于灰分总量不变，有机物料的残留率也略高于有机C的残留率；〓比较宽的玉米秸和稻秸在腐解过程中发生了自生固N作用，但其固N效率仅为C：N=100：0.2-0.9，即每同化100g有机C，只能固定
