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.

As investigated, the shape of the fruit was mainly rotundity, and the color of the fruit were red, black, yellow, mauve. Variation coefficient of mineral elements, which revealed wider variation range and rich genetic diversity. Among them, Fe, the content and the variation coefficient of which was the highest(2.12 mg·100g-1 and 26.99％), it has large potential for futher selection. Ripe fruit of 12 wild myrobalan plum seedlings were analyzed using head space-solid phase microextraction and gas chromatography-mass spectrometry. The results showed considerable genetic variations in these aspects: The total content of volatile components, the classes and contents of each compounds classes, the segregation ratio, and content of main components. There were 83 compounds in total belonging to 6 classes detected in 12 wild myrobalan plum seedlings, including esters, alcohols, ketones, aldehydes, heterocycle and Hydrocarbons. Among them, Formic acid, hexyl ester, the content of which was the highest(4.33 μg·g-1),was important character impact odors.

In general, the influence of the offset can be reduced to a negligible quantity by choosing suitable target size.

当影像平面与目标平面不平行时，圆形标志的像为椭圆，而椭圆中心并不是圆形标志的中心，它存在偏差。

Mitochondria was relatively little in size. Round primary lysosome with high electron-densed granules and secondary lysosome with high or low electron-densed granules were seen frequently. DCs contained many rough endoplasmic reticulum, the Golgi apparatus and ribosomes. The vacuoles with flocculent electron-densed granules were rare. Some special granules in cytoplasm were seen, whose surface like earphone were covered with a membrane. High electron-densed contents in the granules were near one side and the other side was bright. The nucleus became markedly small in volume, nephroid or hoofed in shape. The nucleus had little euchromatin and lots of heterochromatin under nuclear membrane.

In this paper, Newton iteration formula for computing normal depth and critical depth was put forward by mathematical transformation of uniform flow equation and critical flow equation of circular section tunnel. Then, the relationship between the corresponding central angle and the introduced parameters was analyzed. An approximate formula for angle was obtained according to optimal uniform approximation principle. Using this approximate formula as initial value of iteration formula, a direct formula for calculating normal depth and critical depth of circular section tunnel was established after its first iterative.
