为了定量把握结晶器中的钢水流动、钢水过热度及结晶器传热阻力对初期凝固坯壳的凝固不均一的影响，利用水冷铜板的浸渍实验，测定了各种铸造条件下的凝固坯壳厚度、凝固不均一度及树枝晶偏角；利用水力模型实验，并对实机铸坯的凝固组织分析，EPMA对负偏析带的线分析，得出了在结晶器中凝固坯壳上负偏析带的产生原因。

The determined thermal conductivity values vary from 0882 to 678 W/m?K and the calculated heat flow values in Jianghan Basin range from 419 to 609 mW/m2,with a average of 523 mW/m2.It shows that the influence of tectonothermal event before Cenozoic in Jianghan Basin has faded away,and the basin has cooled down.

结果显示江汉盆地热流419～609 mW/m2，平均523 mW/m2，盆地总体表现为较低的大地热流，反映了中新生代以来构造活动逐渐减弱，盆地不断冷却的结果；从盆地内热流分布看，热流分布南高北低，反映了江汉盆地构造活动的不均一性。

Summarily, the crystallizability ofthe soft segments in poly(ether-ester)s seems to be mainly determined by their ownmolecular weight.

同时样品的组成不均一性使得当硬链段含量高到一定程度后，软链段熔点反而有所回升。

The contents of Ni, Au, Mo, W of the deep-seated xenoliths and their host basalts from eastern China are inhomogeneous. The contents of Ni, Au are highest in the mantle-derived xenoliths the contents of Mo, W are highest in the basalts and the mafic granulite, and the leptite and the granitoids, respectively.

地球深部包体中镍、金、钼、钨等成矿元素的含量是不均一的，镍和金在地幔岩包体中含量最高，铝在玄武岩及镁铁质麻粒岩包体中最高，而钨在长英质麻粒岩和花岗岩类包体中含量最高。

Under the scanning electron microscope , for the first time we compare and study both the coalified tracheids through chemical maceration and permineralized tracheid lumen casts. This method reveals the microstructures of wall and perforations of G-type tracheids: 1 The lignified layer of secondary wall is composed of uneven material and further divided into S〓, S〓, S〓 layers; with the smooth enclosing wall, the perforation is internally dumbbell-shaped; 2 In Huia gracilis, the enclosing wall of tracheidal perforation contracts and possesses secondary perforations. The perforation has thickened border facing the tracheid lumen.

本文首次在扫描电子显微镜下对比研究经化学浸解获得的碳质管胞和矿化的管胞腔铸体，明确揭示出了G-型管胞壁层和穿孔的显微结构：1）Hsüa reflexa次生壁木质化层的组成不均一，分为S〓、S〓和S〓层；穿孔腔为哑铃形，腔壁光滑；2）Huia gracilis的穿孔腔收缩，腔壁上发育次级穿孔，孔口具有边缘加厚。

It is illustrated how to determine the actual location of scenario earthquake, based on the inhomogeneity of seismic activity in PSS.

论文首次从地震活动在潜在震源区内的不均一性出发，对设定地震构造位置的确定进行了详细的论述。

These density-dependent factors include increased predation, parasitism, disease, and intraspecific and interspecific competition.

不论群体密度高与低，群体中个体的分布是不均一的。通用分布模式包括群体的，均匀的，随机的。

As a result, a new component called nitrocellulose lead, a form of metallic polymer is thus formed.

在双基药中使用硝棉铅可以克服使用无机或有机的铅盐而导致制造火药工艺中的困难和成分的不均一性及燃烧的不稳定性。

The study on the mechanism of petrogenesis of high-Fe magnesian magmas is important to understand the tectonic regime of magmas in depth, early evolution of crust, the heterogeneity of lower mantle and the interaction of core-mantle. Meanwhile, it is also most significative for us to understand the petrogenesis of high-Fe magnesian rocks discovered from southern Taihang Mountains and other regions, in China.

其成因机制的研究对于理解其岩浆深部构造背景、早期壳－幔演化、下地幔组成不均一性和核幔相互作用有着重要意义；同时，对于最近在我国南太行山地区及其它地区发现的具有高铁镁特征岩石的研究具有极其重要的意义。

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.
