According to their individual shapes, they are Gram positive, catenulate rod-shaped bacteria that can produce elliptical endospore in the middle position. These characteristics are similar to Bacillus cereus' described in Bergey's Manual of Systematic Bacteriology. And the colony States, physiological and biochemical characteristics of the two strains also accord with Bacillus cereus', which suggests that they might be identified as Bacillus cereus.

通过菌株的个体形态观察，发现这两株菌是可以在细胞中间产生不膨胀的椭圆形芽孢的革兰氏阳性杆菌，且相互成链，这与伯杰氏手册中对蜡状芽孢杆菌的描述相似，另外对这两株菌的培养特征、生理生化特征的研究，也表明这两株菌符合蜡状芽孢杆菌的特性，故初步鉴定这两株菌为蜡状芽孢杆菌。

The time passed quietly for half hour, the detonation influence did not have any evanishment sign, this time the formidable shock-wave, already started to sweep away to huge Jupiter, the instantaneous entire Jupiter atmosphere, by the unprecedented formidable shock-wave, is extruded a sliver of ellipse, nearly all must have the stance which swept immediately!

In 1976, the International Astronomical Union revised the definition of the AU for greater precision, defining it as that length for which the Gaussian gravitational constant takes the value 0.01720209895 when the units of measurement are the astronomical units of length, mass and time.

但实际上地球绕日的轨道不是一个圆形，而是一个椭圆形：最初天文单位的定义就是上述椭圆的半长轴的长度。1976年，国际天文学联会把一天文单位定义为一颗质量可忽略、公转轨道不受干扰而且公转周期为365.2568983日的粒子与一个质量相等约一个太阳的物体的距离。

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.

The shapes of the melting solid surface may be concave, convex or plane, while the perimeter of plane contact regions may be rectangular, circular, elliptical, parabolic and arc curve. The types of relative motion reviewed here are the movement of a solid PCM melting inside a heated capsule, the movement of a hot body through a melting solid medium, slide contact and rolling contact. The contact melting may be caused by temperature difference, pressure difference, friction and viscous heating. Finally, the research regions in the future are summarized.

The common capacitance sensor is composed of two-electrode planks which vary in shape and can be fixed in different plane of space. The driving and inductive electrode pole placed in the same plane of the uniplanar scattering-field capacitive sensor. The electric field presents scattering. As the shape of power line in the electric fields is like semicircular arc or ellipse, there is some limits in the measurement depth of uniplanar scattering-field capacitive sensor, and its penetration depth is equal to 2/3 of center distance of adjacent driving and irritable electrode pole.
