During the manufacturing of the critical intermediate cephalosporin nucleus --7-amino-3-chloro-cephalosporanic acid diphenylmethyl ester hydrochloride salt, first the feasibility of the one-pot synthetic route of open loop, closed loop and ozonization when chlorine is passed over is qualified by experiments. Then the critical factors that will influence this reaction are studied as follows: the mol ratio of triphenyl phosphite and Diphenylmethyl 3-hydroxy-7-phenylacetaminoceph-3-em-4-carboxylate-l-oxide is four to one; the quantity of the stablizer should be at least more than two to one. The temperature of the system must be 25℃ when chlorine is passed over so that the hydrochloride can be precipitated to obtain cephalosporin nucleus of cefaclor--7-amino-3-chloro-cephalosporanic acid diphenylmethyl ester hydrochloride salt.

Firstly, we used the Raman scattering method which can calibrate in real time to measure the O2 (a1 Δ) yield of SOG for the first time in China. The measurement relative error is less than 8%. Based on the data from the experiments, we report the results that the diluent category and ratios influence the O2 (a1 Δ) yield. The relationship of P-τ values and the O2 (a1 Δ) yield of this SOG were given. The effects of distance and bypass of gas transportation on the O2 (a1 Δ) yield are investigated. Secondly, the chlorine utilization was measured by using Raman spectroscopy simultaneously when the O2 (a1 Δ) yield was measured. This method originated with us. The result about the chlorine utilization is coincident with other theoretic and experimental conclusions. The relationship given in this paper between gas stay time in SOG and chlorine utilization offers reference to improve the reaction efficiency and chemical efficiency of COIL. Finally, the partial water vapor pressure at the exit of SOG was measured by absorption spectroscopy. The water vapor fraction and partial pressure have trends changed with the generator total pressure, the diluentratios, and the BHP temperature. These experimental results are very important to improve experimental conditions of SOG, reduce the water vapor fraction, and enhance the output power of COIL.

由侧得的数据得到了加入稀释气体、稀释气体种类以及稀释比例对单重态氧产率的影响，给出了该发生器P一：值与仇产率的关系，还考察了传输距离对仇产率的影响；在国际上首创利用喇曼散射光谱法在侧量产率的同时进行了氯气利用率的检侧，侧试结果与其他理论及实验结果十分相近；给出了气体在发生器中的滞留时间与氯气利用率之间的关系，该结果为提高氧碘化学激光器的反应效率和化学效率提供了参考依据；另外采用了吸收光谱法对发生器出口处的水汽含量进行了测量、得到了水汽分压和百分含量随着发生器压力、稀释气体比例以及BHP温度等的变化情况，该实验结果对于改进发生器工作条件、减少水汽含量、提高氧碘化学激光器的出光功率具有十分重要的指导意义。

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。
