查询词典 heterogeneity

Not only the permeability of the rock salt body, the convergence of the cavity and the stability of jambs must be considered , but also the heterogeneity of the interlayers must be full considered, like the permeability of interlayers and layers , the difference of interlayers .

不仅要考虑岩盐矿体的渗透性、溶腔的蠕变收敛性、矿柱的稳定性外，还要充分考虑夹层的不均质性，如夹层及层理的渗透性，夹层和盐层蠕变的差异性。层状岩盐矿床中建造油气储库是一个相当复杂而且涉及很多学科的深部岩土工程。

因此除了具有较大的预期种群大小外，大生境片断中种群灭绝风险较小的一个重要原因、很可能是因为大斑块生境质量的异质性比小斑块高。

Managing in an enterprise context requires that entities be named uniquely and locatable within the enterprise, that heterogeneity of platforms and services may be assumed, and that the dynamic nature of the environment is taken into account.

在企业中进行管理需要企业中的所有实体都必须惟一命名，并且位于企业范围之内，同时还需要支持所有异构的平台和服务，当然，企业环境的一些动态特性也需要加以考虑。

On the landscape level, the regional landscape heterogeneity is increased and the connectivity reduced, which presents the increase of Shannon's diversity index and Evenness Index, decrease of dominance index and increase of fragmentation index. On the class level, it shows that human disturbance on landscape is intense during the past five years, anti the disturbance to artificial landscape mote intense luau that on semi-natural landscape, which means that the fragmentation index of semi-natural landscape is relatively smaller while that of the artificial landscape is larger.

从景观水平上看，区域景观异质性在增大，景观斑块的连通性降低，表现为多样性指数和均匀度指数呈增加，优势度指数减小；从类型水平上看，5年间人类对景观的干预程度较大，对人工景观的干扰强于半自然景观，体现在半自然景观类型的分离度较小，而人工景观类型的分离度较大。

Some geologists,however,on the basis of observations concerning mantle xenoliths, argue that the mantle is not layered,but that heterogeneity is created by fluids rich in "incompatible elements" percolating upward and transforming portions of the upper mantle irregularly,according to the vagaries of the fluids' pathways.

但是，某些地质学家，以对地幔捕虏岩体所作的观察为依据，指出地幔并非是分层排列的，相反，地幔的异质性是由那些富含&不相容成分&的流质构成的，这些成分趋向于流体而非固体的状态，自下而上渗透扩散，并依照这些流质流向的任意性，不规则地将上部地幔的某些部分予以改变。

Some geologists,however,on the basis of observations concerning mantle xenoliths,argue that the mantle is not layered,but that heterogeneity is created by fluids rich in "incompatible elements"(elements tending toward liquid rather than solid state)percolating upward and transforming portions of the upper mantle irregularly,according to the vagaries of the fluids'pathways.

It is doubtless that the research on damage behavior and ductile fracture of weldments with mechanical heterogeneity is practically significant for the assessment of the integrity of welded structures.

研究焊接接头这种力学性能不均匀体的损伤行为及韧性断裂，对于焊接结构的安全性评定，具有重要的理论与工程实际意义。

However, when the 3 individual outcomes (myocardial ischemia, stroke and peripheral vascular disease) were evaluated separately, only the relative risk reduction for peripheral vascular disease was effectively reduced:(stroke 7.3%, MI _3.7% and PVD 23.8%) The trialists attributed the discrepancy in the stroke group to the heterogeneity of the disorder, a correct but frequently overlooked observation.

然而，当我们分别对这三类患者结局（心肌缺血，卒中和周围血管病）单独分析时发现，仅周围血管病患者的相对危险降低率减少有显著意义（卒中组7.3％，心肌缺血组-3.7％，周围血管病组23.8％）。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
