The emission of N_2 in discharge gap is detected using optical emission spectrophy. The discharge reactor was put in lightproof box to avoid the disturbance from outside lights. A small hole was drilled in one sidewall of the box, and the fibre was mounted coupling to the inlet (1mm) into the hole. A tube with the inner diameter of 1.1mm was set in the front of the hole. In this way, only the light from a certain direction emitted from the discharge reactor could transfer into the inlet through the tube. The reactor could be moved in the vertical direction of the fibre, and the spectrometry can collect the total emission along the fibre inlet in single-shot measurement.

The effects of several components in the culture medium on Lithospermum erythrorhizon cell growth and secondary metabolite synthesis were studied, as well as structural dynamic model. The two-liquid-phase culture of Lithospermum erythrorhizon was carried out by choosing the proper organic solvent as the second phase. The bioactive carrier for adsorption was prepared and the condition of cell immobilization was determined. We combined the technique of two-liquid-phase culture and immobilization to carry out the culture. We chose the suitable type of reactor, studied its characteristics and results of cell culture using this reactor. The fed-batch operation was also studied on the basis of twoliquid-phase culture and immobilization used in culture in the reactor.

There are three platinum catalyst micro channels which have different width ,such as 1000 m , 400m and 40m. The platinum catalyst micro channel reactor is fabricated by MEMS technology. The reactor uses the exothermic reaction of hydrogen and oxygen on the platinum catalyst plate as the heat source and the platinum thin film resistance deposited on a glass chip by face micro machining process as catalyst and temperature sensor. The channel is bonded with a cover plate etched by bulk micromachining technology to become a mico- channel reactor.

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.
