    A study on the accumulation of free proline in two species of mosses, Plagiomnium acutum ( Lindb. ) T.Kop. and Thuidium cymbifolium ( Doz. et Molk. ) Doz. et Molk. under high temperature stress was carried out in Apr. 2000. The results showed that the high temperature stress as well as water stress could cause the proline accumulation in mosses under high temperature stress. The free proline contents in the samples increased with the rise of temperature and the prolonging of time within a certain range of temperature stress. The relationship between the average value of free proline content and the temperature is an S - formed curve. When the temperature rose f rom 35 ℃ to 50 ℃, the free proline contents increased by about 3 times.

    Because the fruiting rate and germinat ive percentage of Gerbe rajame sonii Bolus are lower, tissue culture was explored to solve the propagating problem in the product ion. The results show that the shoot-tip is the best mate rial in speeding propagation among the three explants ( shoot- tip, stem and petiole) as it has the bigges tinductivity,the best growth and it is easy to be inducted adventitious buds.The suitable phytohormone compositions toninduct callus, adventitious buds and roots are respectively: MS+ BA 1. 0 mg•L-1+ IBA 0. 05mg•L-1+sugar 3.0%, Ms+BA2. 0 mg•L-1+ IAA 0. 5 mg•L-1+ sugar 3. 0% or Ms+ Kt 3. 0 mg•L-1+ IAA 0. 05 mg•L-1+ sugar 3. 0% , and Ms+ NAA 0. 3 mg•L-1+ IBA 0. 3 mg•L-1+ sugar 3. 0%.

    The paper reports that micronucleus test technique of Vicia faba root tips has been used in monitoring the pollution of Fengyu Lake in Jishou City. The results of statistical analysis show that each of the samples can make the micronucleus frequence of Vicia faba go up. The micronucleus frequence in Saziao, the Entrance, the Synthetial Building and the Hospi tal reach 10. 95‰, 13. 58‰, 7.94‰ and 6. 77‰, The micronu cleus frequence in the east of the Bridge, the west of the Bridge, the side of Road and the Exitr each 12. 03‰, 10. 84‰, 8. 05‰ and 12. 76‰. The result shows: Saziao and the Entrance are the mos t serious pollution sources, and the ability of water purification is very weak.

    We adopt a semi- classical model and study the potential distribution of a one-dim mesoscopic tunnel junction array when there are many excess electrons in it. We show that there exist multi- charge solitons in one-dim array of mesoscopic tunnel junctions. The main feature of a multi- charge soliton is that its potential peak splits into many peaks. Each island that contains an excess electron corresponds to a potential peak. Meanwhile, we find that the single charge soliton equivalent is also applicable in dealing with multi- charge solitons.

    The IMF is one of three mainstays of postwar international economic order, its functions mainly include:Exercising surveil lance of exchange rate , providing temporary financial as sistance and promoting international economic cooperation.Though the IMF plays an important role in the international financial mechanism, with the development of economic inte gration and financial globalization, it has to be reformed . The thinking of reform of the IMF is discussed from strengthening the status and effect of developing countries in IMF , establishing pre-warning mechanism of financial situation , establishing reserves and improving the supervision of the international capital flows.
