The fabrication of fibers was attempted. The copolymers, the copolymers containing MOCT and the copolymer films containing MOCT were characterized by using Fourier Transform Infrared Spectroscopy, Scanning Electron Microscopy, Differential Scanning Calorimetry, Thermogravimetric Analyzer and X-ray Diffraction etc. The conclusions were summarized as following,1. The AN/MMA copolymers were testified that copolymerization of most AN and MMA occurred and the ratio of AN and MMA in copolymer was less than the ratio of monomers. With the increase of the contents of MMA, the viscosity of copolymer solution, molecular weight and decomposition temperature of copolymers increase.

Carl Sagan has entertainingly described this phenomenon, musing about the destiny of bacteria that reproduce by dividing into two every 15 minutes. Says Sagan:"That means four doublings an hour, and 96 doublings a day. Although a bacterium weighs only about a trillionth of a gram, its descendants, after a day of wild asexual abandon, will collectively weigh as much as a mountain...in two days, more than the sun - and before very long, everything in the universe will be made of bacteria." Not to worry, says Sagan: Some obstacle always impedes this kind of exponential growth.

Carl Sagan 曾经开玩笑地解释这种现象,假设有一种细菌每 15 分钟可以分裂一次,亦即代表每一小时复制四次,一天可复制 96 次,虽然单一个细菌其重量只有一兆分之一公克重,但是只要经过一天无止尽的无性生殖,其重量可能会比一座山还重,经过两天后,甚至会比太阳还重,要不了多久所有的宇宙都将由这种细菌所组成,不过 Sagan 又说,大家不必担心,上天一定会安排障碍来阻止其倍数成长,有可能他会耗尽食物,或是毒死自己,或是有可能羞于在大庭广众之下复制。

The main results were as follows:An appropriate concentration of ethephon sprayed on leaves of peanut made stems and branchs height shorter,but more branches;The fresh weight and dry weight per unit of leaf area and per plant increased;It optimized some physiological and biochemical characteristics in the leaves.It was showed that the ethephon increased obviously the contents of protein and chlorophyll and the activity of SOD and POD in the leaves,and improved the rates of photosynthesis and transpiration of the leaves,and increased the activity of the roots,but decreased the content of MDA in the leaves;It improved the quantity of pods,the percentage of plumy pods and the peanut yield.

结果表明:喷施适宜浓度的乙烯利可使植株相对矮化,抑制花生地上部分的生长,使主茎和分枝长比对照短,但分枝数较多;提高单位叶面积鲜重、干重以及植株鲜重、干重;优化花生植株的生理生化特性,表现为显著提高了花生叶片的蛋白质含量和叶绿素含量及SOD和POD活性,增强了花生叶片的光合速率和蒸腾速率,增强了主根活力,降低了花生叶片的丙二醛和可溶性糖含量;提高植株的单株结荚数、饱果率和产量。

将煤成气重烃含量与油型气重烃含量相比可知,油型气重烃含量多数介于5%~30%,这说明煤成气比油型气重烃含量偏低。

During the early growth stage of seedlings, basal stem diameter and paripinnate number were decreased with the increasing of shade, taproot length, root : shoot ratio, total dry weight and leaf area per seedling were maximal under 37.3% NS, specific leaf area was increased with the increasing of shade, but the relative growth rate was declined. Seedlings grew fastest under 0.6% NS, suggesting that nutrients stored in seeds played an important role at the early growth stage. The treatment of 37.3% NS was best for established seedlings in seedling height, basal stem diameter, paripinnate number, rachis length, the maximum sub-leaflet number of individual paripinnate, leaf area per seedling, relative growth rate and net assimilation rate. Light intensity was positively correlated to total dry weight, and negatively to specific leaf area. The maximum of SLA was observed under 15.5% NS.
