It was found that both the conversion and the initiating efficiency of methyl methacrylate polymerization system were decreased in the presence of small amounts of addition inhibitions 2,4,6-trinitrophenol or Benzoquinone, the system exhibited some retardation characteristics; at the same time, the molecular weights of obtained polymers was small and the molecular weight distributions was narrow, it was suggested that this polymerization system exhibited some ""living""/controlled radical polymerization characteristics.

发现在甲基丙烯酸甲酯的普通自由基聚合体系中加入少量的加成型阻聚剂2，4，6-三硝基苯酚或1，4-苯醌时，体系转化率降低，引发效率降低，呈现出一定的缓聚性质：同时得到的聚合物分子量变小，分子量分布变窄，具有一定的&活性&/可控的特征。

The oxidation of solid biurea with chlorine in aqueous solution to produce azodicarbonamide was experimentally studied in a 1 L agitated glass vessel with a four-blade paddle stirrer. Based on the film theory, a model is first developed for this system by taking the gas-liquid and solid-liquid mass transfer, solid dissolution, and instantaneous reaction between the dissolved reactants into consideration.

在玻璃搅拌反应器中进行了固体联二脲与氯气液相氧化反应生成发泡剂 ADC过程的传质与动力学实验，提出了基于双膜理论的数学模型，以描述这一反应系统所涉及的气液和固液传质、固体溶解以及溶解物在液相中发生瞬间反应，特别是随反应进行固体反应物粒径变小导致固液传质速率减小的复杂过程。

Wing bud differentiation initiated at the early 5th nymphal instar, during which the front wing bud cells in the macropterous proliferated much more rapidly than those in the brachypterous. The hinder wing buds of the brachypterous degeneratd at middle 5th instar and finally turned out to be very little wings.

在5龄初始时才发生翅芽发育的分化，之后，短翅型若虫的前翅芽细胞增殖速度明显慢于长翅型，到五龄末期，细胞数量积累明显少于长翅型，短翅型的后翅芽在5龄中期开始退化变短，羽化后变成一个退化的小翅。

On the other hand the inflammation of bronchiolar and block of the lung small vessels cause the disproportion of the ventilation and flow of blood and the disorder of the diffusion function,in turn the hyoxemia and the repiratory failure would occurrence.

此外，细支气管的炎变以及肺小血管的闭塞引起通气血流比例失调和弥散能力降低，最终发生低氧血症及呼吸衰竭。

Lateral branches penetrating leaf sheaths. Leaves alternate. Inflorescences borne at each node, opposite leaves, emerging from mouth of leaf sheath, each a large panicle of numerous cincinni; cincinni each subtended by an involucral bract; bracts similar to leaves, becoming smaller toward apex of cincinnus.

叶互生 花序着生在每节，与叶对生，从叶鞘口那里出现，每一个为一大的多数蝎尾状聚伞花序的圆锥花序；蝎尾状聚伞花序各自以一总苞片被包着；类似于叶的苞片，向蝎尾状聚伞花序先端变小。

In chapter 2, the intensity and phase formulae of five photorefractive processes in intermediate regime are derived including the analytic expressions of codirectional parallel-or cross-polarization two-wave mixing in the depleted pump condition and the analytic expressions of contradirectional parallel-or cross-polarization two-wave mixing and degenerate four-wave mixing in the undepleted pump approximation.
