The sloping plate can provide sufficiently the under-cooling for nucleation and lay a foundation for heterogeneous nucleation to form lots of nuclei of crystal internally and on the sloping plate surface, thus causing the melt to nucleates eruptively. Under the action of both metal flow and vibration, the nuclei formed on the sloping plate surface can move freely and disperse into the melt, and they are able to maintain the direct growth in spherical shape in the homogeneous composition and temperature fields.

倾斜板为形核提供足够大的过冷度和异质形核基础，大量晶核在斜板表面和内部形成，使熔体爆发形核，在流动和振动作用下斜板表面形成的晶核游离，弥散到熔体内部，晶核在均匀的成分场与温度场条件下，可以保持直接球状生长。

The deformation mechanism is mainly the single-slip and cross-ship, the fracture mechanism is mainly the congregation of transgranular micro-hole, and large uniform deformation occurred before tough fracture, and therefore, the ability of plastic deformation and the mechanical properties of the material were remarkably improved. These fully indicate that the new melt-treatment developed in this work is an effective and advanced technique, and further testify that the improvement of metallurgical quality of the material is the key to enhance its mechanical properties, especially its plastic deformation performance. The results of tensile and compression tests at elevated temperature also indicate that the suitable hot-working temperature range is 400～450℃. 4. A steady-state plastic flow exists during the plastic deformation of the aluminum sheet used for pressure can at elevated temperature. A hyperbolic sine relationship can be satisfied between the steady-state flow stress and strain rate by introducing an Arrhenius term which involves some thermal activation parameters, i.

压力罐用铝材中的主要冶金缺陷为Al〓O〓夹杂物、气孔及富Fe杂质相；高效熔体处理显著改善了材料的冶金缺陷的存在形态，使含杂量明显减少、夹杂物尺寸变细小且分布均匀，富Fe杂质相变为细小、分布均匀的团球状或短棒状的复杂化合物，同时也明显细化了结晶组织；此外，由于高效熔体处理有效地减少了材料中裂纹萌生源数量，因而改变了材料的塑性变形微观过程及断裂方式，主要以单滑移和交滑移进行塑性变形，断裂方式为穿晶微孔聚集型，韧性断裂前产生了大量的均匀变形，不易出现变形失稳，从而显著提高了罐用铝材的塑变能力和力学性能。

Cytoplasmic polyhedrosis virus is an insect virus belonging to Reoviridae family, which is a group of segmented, double-stranded RNA icosahedral viruses.

质多角体病毒属呼肠孤病毒科，是具有十段双链RNA片段的二十面体球状病毒。

This study was only focused on the No.Ⅰore body. Based on detailed logging and dating results, it is considered that mineralization of the Cu_Au porphyry occurred in Late Jurassic. The formation of the ore body is related to the Late Jurassic augen quartz phenocryst_bearing hornblende_quartz diorite porphyrite intrusion（J3δομ）.

通过对雄村铜金矿床Ⅰ号矿体详细的地质编录和测年成果，发现雄村斑岩型铜矿床形成于晚侏罗世，矿体的形成与晚侏罗世侵位的、含眼球状石英斑晶的闪长玢岩（J3δομ）有关，成矿岩体呈不规则的岩枝状，全岩矿化，岩体中Au的平均品位大于1g/t，Cu含量大于0.7 %。

The cytoderm of the thalli contained glycerol diether derivatives with halophilous archaea characters. The shape of the thalli was spherical and the colony was orange red, which was identified as halophilous archaea, Halorubrum genus based on the physiological and biochemical identification and l6S rDNA gene sequence homologous analysis.

结果］SYM菌株能在饱和NaCl浓度下生长，菌体细胞壁含有嗜盐古细菌特征性的甘油二醚衍生物，菌体形态为球状，菌落显橙红，经生理生化和16 SrD-NA基因序列同源性分析鉴定为嗜盐古细菌嗜盐深红菌属。

A variety of ordered bulk phases, including lamellae, hexagonally packed cylinders, body-centered-cubic spheres, and a bicontinuous network structure called Gyroid are observed for diblock copolymers.

在熔体状态下，双嵌段共聚物可以自组装形成包括层状相、六角排列柱状相、体心立方球状相和双连通Gyroid相的一系列稳定有序结构。

However, semi-steel is made of 10 ~ 20% cementite and pearlitic matrix, there exists no pellet-shaped graphite, so sticking is easy to happen to it, which is not expected dunng rolling.

然而半钢材质是由10-20％渗碳体及珠光体基体所组成，其内不存在球状石墨，所以半钢材质容易产生粘钢现象，这是轧制过程所不希望的。

The female prosopon body oval,body long 2.3-3.5mm,antenna 7,the body by the white cotton and kapok shape wax silk,many insect\'s wax silk often is fused densely in together,forms the cotton and kapok to be spherical,after the dewaxing the insect body becomes the purple red.

雌成虫体卵形，体长2.3—3.5mm，触角7节，体密被白色棉状蜡丝，多个虫的蜡丝常融合在一起，形成棉球状，去蜡后虫体成紫红色。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
