The tryptophan residues play important roles in DNA photoreactivation catalyzed by CPD photolyases. We have investigated the action mechanism concerning Trp in DNA photoreactivation, and obtained the results as follows: 1 We proposed a mechanism of photosensitized splitting of CPDs by Trp and Trp-containing peptides. 2 Quantum yields of splitting of the model compounds that a Trp linked covalently a CPD were obtained under 290 nm light in various solvents, these values changing with solvent, range from 0.01 to 0.5. 3 Utilizing pulse radiolysis technique, splitting processes were observed in aqueous solution of the CPDs with hydrated electron and some oxidative species (such as hydroxyl radical, bromic radical and azide radical), and obtained their rate constants. In the case of interaction between CPD and hydrated electron, splitting of the CPD anion, and pyrimidine anion transfer an electron to FAD or Rf, were observed. The process rate was slower one order more than that in photolyase. Minor, but highly mutagenic UV-light-induced lesions are (6-4) photoproducts, which are repaired by (6-4) photolyases. These enzymes, discovered in 1993, are not well characterized and their mechanism is still under investigation.

The relationship between weed invasion and intensity was analysed on sown pasture mixed by whiteclover and perennial ryegrass,and the preliminary results were that 1the number of invasive weeds ismainly dependent on grazing intensity;2the trend of species diversity was successively increase-decrease-increase when the grazing intensity is increase;3 principal invasion weed species are Lysimachiahemsleyana, Eragrostis nigra, etc,8 species;4the sown pasture in question is pioneer stage of the recoverysucce...

本文分析了白三叶草十多年生黑麦草混播人工草地上杂草入侵与放牧强度之间的关系，得出如下初步结论：1）杂草入侵的种数主要决定于放牧强度；2）α物种多样性随放牧加重而有增－减－增的趋势；3）入侵的主要杂草种为点腺过路黄等8个种；4）所论人工草地都处在恢复演替的先锋阶段，因而草地退化的进程还是能予以遏制的。

The traveling birds will carry,like always ,my dress made of light clouds,up to the warm countries at the edge of the world,where I will wait for one year till I come back again...and I feel very sorry for that tree who remains alone,without song...I have hardly convinced him to turm green again after he had got dry ofr so much loneliness...If he remains alone precisely now,he will surely die of sadness...Please caress him with your warm sun and tell him I will miss him and next year I shall come again to wake him up to life,by singing leaf songs.

旅行的鸟儿会像往常一样，把我用浮云做成的霓裳带到世界边缘温暖的国度，我会在那里等待一年，直到我再次归来……我对仍是孑然一身、没有歌声的那棵树感到非常抱歉……我几乎无法使他相信，在他因过分孤单而干枯后，还能再次穿上绿衣……如果他此时此刻仍孑然一身，他一定悲哀而死……请用你的温暖的阳光爱抚他，告诉他我会想念他，来年我还会回来，用树叶的歌声将他唤醒，使他恢复生机。
