Both of the thermophiles were motile by means of lophotrichous flagella and had high growth rate on medium containing cellulose. Optimal growth occured at 60℃ for the two thermophiles and at PH 7. 5 for Y, PH 7. 37. 5 for W strain. Y strain produced yellow pigment in cellulose medium and had yellow-colored, round or watery colonies in cellulose agar. The colonies of W strain were white -colored and similar in form to that of Y strain. The mesophile, Clostridium sp. B, was motile with peritrichous flagella. The colonies grown on cellulose agar were white and round with slightly undulate margins. The optimal growth temperature and PH of B strain were 40℃ and 7. 0-7. 2, respectively. All of the three Clostridia fermented varieties of carbohydrates and in cellulose media produced the similar end-products: CO〓H〓, ethanol and acetic acid. The DNA compositions were 34 mol% for Y and B, 35 mol% for W strain.

Growth layer existing in PbWO 4 crystals were investigated with optical microscope and electron microprobe and were recognized to be platinum particles.

利用光学显微镜和电子探针研究了存在于钨酸铅晶体中的生长层，确定这些生长层的成分为固体的铂金颗粒。

Pollen grains germinated soon after pollination. Pollen tubes grew first into the intercellular space of branched penniform stigma and then through the intercellular space of transmitting tissue into the top of the ovary, further penetrating the ovary wall and primine to the micropyle. Green fluorescence was found in both pollen and pollen tubes.

结果表明：授粉后，花粉随即萌发，花粉管进人羽毛状柱头分支结构的细胞间隙，继续生长于花柱至子房顶部的引导组织的细胞间隙中，而后进入子房，在子房壁与外珠被之间的缝隙中向珠孔方向生长，花粉与花粉管均具有明显的绿色荧光。

The results showed that the ET from the marsh had an obvious seasonal variation, with the lowest month-average daily ET in May and the highest one in July. The average daily ET in growth season was 1.94 mmd^(-1), and the total ET was 293 mm.

结果表明：生长季内（5-9月），研究区沼泽湿地蒸散发具有明显的季节变化，月均日蒸散量在5月最低、7月最高；生长季内平均蒸散发为1.94mmd^(-1)，总蒸散量293mm。
