The results of IR and XRD for ground cement components show that grinding aids accelerate breakage of chemical bonds especially of Si—O bond in C〓S mineral, enhance crystal lattice distortion, crystal defect and amorphism, thereby enhancing activity of ground materials.

助磨剂作用下磨细物料的XRD、IR分析结果表明：助磨剂加剧了物料的晶格畸变、晶格缺陷及无定形化，加速了物料结构中化学键的破坏，尤其是C〓S矿物中Si—O键的断裂，从而增加物料的反应活性。

There were abundant Botryococcus braunii fossils and relevant degraded amorphism in the main hydrocarbon source rocks. So, it is further proved that Botryococcusbraunii was an important composing of alga parent material for the hydrocarbon generation of the Triassic in the Ordos Basin.

主要烃源岩中富含葡萄藻化石及其降解形成的无定形有机质，进一步证明葡萄藻可能是鄂尔多斯盆地三叠系陆相石油藻类母质的重要组成。

The results showed that high-energy ball milling led to a drop in the crystallinity of the CMs and a decrease in the size of graphite planar micro-crystals,implying a higher structural amorphism caused by the high energy ball milling.

结果表明，高能球磨处理导致中间相的结晶有序度下降，微晶石墨平面尺寸减小，层间间距增加，说明高能球磨处理促使中间相向无定形结构转变。

The mesoporous sieve of the M41S family has framewoks with pore diameters withinthe mesoporous range(2～10nm), huge surfaces areas about 1000cm2/g and amorphism porouswall tent to incorporate hetero atom so that has been used abroad in big moleculer catalysisand separation, life science and environment protection fields and so on.

It is an amorphous solid—a state somewhere between those two states of matter.

它是一个无定形的固体–介于这两种物态间的一种状态。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
