The results showed that as low temperature became intensified and prolonged, the leaves of pepper seedling presented increased POD activity, decreaseds SOD and CAT activities, increased MDA content and increased plasm-membrane permeability; the critical temperature (15℃/8℃) showed stronger effects on pepper plants than the lower temperature (19℃/12℃); under the lower temperature, the weak light of 90μmolm^(-2)s(-1) could make the POD activity increase much more, but reduce the decrements of the SOD and CAT activities, and the increments of the MDA content and plasm-membrane permeability, and under the critical temperature (15℃/8℃), an opposite situation occurred.

结果表明：随着低温弱光胁迫程度和时间的增加，辣椒幼苗叶片中POD活性提高，但SOD和CAT活性下降，MDA含量增加，细胞膜透性增大；就温度而言，临界低温(15℃/8℃)比偏低温(19℃/12℃)对植株的影响更为显著；在偏低温(19℃/12℃)下，弱光90μmolm^(-2)s(-1)使POD活性上升更大，而SOD和CAT活性的下降、MDA含量的增加和细胞膜透性的增大更小，而在临界低温(15℃/8℃)下则相反；陇椒2号耐低温弱光能力强，各项指标均优于七寸红。

Usually, the coating of dental ceramic materials is performed with use of flexible discs, silicone polishers, diamond polishing pastes and finishing diamonds.

通常，齿科陶瓷材料的抛光是采用硅磨光器，金刚石抛光浆和抛光钻来完成的。

This is a new kind of photoinduced phenomenon and it is a one-photon process.(2)A bipolaron is split into two polarons by photoexcitation.This photoinduced splitting converts a charge carrier into two spin carriers.(3)When the hopping effect is included, the energy of a soliton-antisoliton pair can be lower than that of single polaron in conducting polymers with degenerate ground state.

这是一种新的单光子过程光致现象；（2）通过光激发，一个双极化子可以分裂成两个极化子，这种光致分裂效应将一个荷电载流子转换为两个自旋载流子；（3）对具有简并基态的导电聚合物，如果计及跃变常数的变化这一效应，孤子-反孤子对的能量可以低于单个极化子的能量。

Polymers are no more complex to produce than colour crystal.There are no filters, no polarisers and no backlighting, light is emitted off the front surface.

生产聚合物没有生产彩色晶体复杂，它们没有滤光镜、没有偏光镜、没有背光，光从正面发射出来。

Its basic principle is to monitor the arc light automatically by the photosensors; the photoelectric signal is analysed and processed automatically by the microprocessor, then it drives the liquid crystal light valve to turn from a "clear state" into a "dark" protective state rapidly . Meanwhile , when the arc light disappears, the system makes the liquid crystal light valve resumed the bright attitude by auto-delay,and microprocessor adjusts eye protection circuit intelligently to reduce the consumption in the maximal degree, which make the working time achieved one or two years by ordinary button cell cooperates with photocells .

其基本原理是由光敏器件自动监测弧光，光电信号经微处理器自动分析处理，快速驱动液晶光阀由透明的亮态迅速变为保护的暗态，当弧光消失时自动延时使液晶光阀恢复亮态；并且微处理器智能调整护目镜电路的工作姿态，最大程度降低功耗，使得普通的扣式电池配合光电池便可以工作一至两年。

It shall be flattened first with wood float and then press polished with iron float by pressing all sand grains into grouts.

二遍压光：混凝土在临近终凝前进行二遍压光，选用木抹子压平后用铁抹子进行压光，将砂粒全部压入水泥浆内。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
