There are two stages in the collapse of CaSiO_3 perovskite under decompression: the breakage of SiO_6 octahedron and the breakage of CaO_(12) icosahedron.

钙钛矿型CaSiO_3解压缩成非晶态时，存在两个结构破坏阶段：破坏硅氧八面体和破坏钙氧二十面体。

The physical characteristic of weathered lamprophyre has impenetrability and nonhomogeneity, however, the YDS epoxy resin possesses initial viscosity, strong affinity to mediums, excellent permeability and good ageing property. After chemical grouting, the rock mechanics characteristics are improved greatly and can meet the design requirements, it indicates that lamprophyre can be grouted by YDS epoxy resin.

为此，采用了高渗透性的YDS环氧材料对风化后的煌斑岩脉进行纯压式灌浆试验，试验结果表明：通过YDS改性环氧浆液的"浸透""浸渗"加固处理，风化的煌斑岩脉力学性能大幅提高，基本能满足设计的力学指标要求。

This is probably because a fetus starved of oxygen will send oxygenated blood to the brain in preference to the rest of the body.

这可能是因为一个缺乏氧的胚胎会首先把充氧的血液输送到脑部，然后才送到身体的其他部位。

The degradation and removal of nitrogenous heterocyclic compound-pyridine under aeration stripping, aerobic, anoxia, anaerobic conditions and co-metabolism with quinoline, 2-methylpyridine, aniline, indene, naphthalene in A2/O process were conducted by flask-shaking tests.

The removal pathways are: fist, high-energy electrons undergo an inelastic collision with target molecule, and transfers all or part of its kinetic energy to molecule. Inelastic collisions result in a charge to the target molecule such as ionization, dissociation or excitation.

其可能的途经是：首先，高能电子经过与目标分子发生非弹性碰撞，将能量全部或部分传递给分子，使其裂解，激化等；接着，上述被高能电子裂解、激化的分子在臭氧和氧等离子的作用下，被氧化成CO2、CO和H2O。

Thirty patients (M 23, F 7; age 50 a±s 15 a) with chronic eczema were treated with etofesalamide ointment (given th inly on the surface 3 times daily) for 4 wk; Another 30 patients (M 24, F 6; age 44 a±14 a) were treated with ointment base (given thinly on the surface 3 tim es daily) for 4 wk.

60例慢性湿疹病人，30例(男性23例，女性7例；年龄50 a±s 15 a)用乙氧苯柳胺软膏均匀涂布患处，tid， 4 wk为一个疗程；另30例(男性24例，女性6例，年龄44 a±14 a)采用乙氧苯柳胺软膏基质均匀涂敷患处，tid， 4 wk为一个疗程。
