查询词典 heterogeneity

Dyskeratosis congenita is a rare inherited syndrome exhibiting marked clinical and genetic heterogeneity. It is characterised by mucocutaneous abnormalities, bone marrow failure and a predisposition to cancer.

A digital image -based technique was proposed to characterize and quantify the heterogeneity of rock, and it was implemented into RFPA code in order to simulate the complete failure process of rock under both the exter

本文提出了用数字图像处理技术表征岩石非均匀性的基本方法，并通过把该技术实施到岩石破裂过程分析程序RFPA中，来模拟非均匀岩石在外载荷和渗流耦合作用下发生破裂的整个过程。

It has been thought that the complicated gene-gene interaction, heterogeneity of clinical presentation and numerous farraginous experimental data make it more difficult to draw a firm conclusion with genetic research work.

这主要是因为精神分裂症临床分型复杂，症状多样，若将不同类型的患者混杂起来研究将难以对这种异质性疾病作出可信的结论；同时该病作为多基因病的一种，其发病是由许多微效基因共同作用决定的，若孤立地研究某个候选基因或候选染色体区域与疾病的关系，也难以得出满意的结果；而且在研究结果的分析中，某个基因对发病的微小贡献将被&淹没&在巨大的数据信息中，难以提取。

For morphosis,young stage multifidus MRI charactered as full shape,evenness and regular outline,uniformity low signal,intramuscular spatia being revealed none or as single line,puncta form;however,old stage multifidus MRI charactered as atrophy shape,introcession outline,heterogeneity higher signal,intramuscularly spatial being revealed as multiple line-lamellar form or featheriness or grid form.

在形态结构方面，年轻组多裂肌表现为形态饱满、轮廓平整、均匀低信号、肌内间隙不显示或呈单个线状或点状显示；老年组多裂肌表现为形态萎缩、轮廓凹陷、信号不均匀性增高、肌内间隙呈多发线片状、羽毛状或网格状显示。

In fractural area, because the elasticity is heterogeneity, seismic wave absorbed and scattering, the seismic record is more complex. Thus, the Hurst exponent in fractural area is less than in non-fractural one.

在裂缝发育区段，由于地层介质弹性的非均质性及地震波的散射、吸收等使得地震反射序列变得更为复杂，这样，裂缝发育区地震信号的赫斯特指数小于非裂缝发育区。

The average heat production rate of the crust also exhibits lateral heterogeneity among geotectonic units, implyin...

中国大陆各构造单元的地壳生热率亦表现出横向非均匀性，这意味着各构造单元的地壳平均成分存在显著的横向变化。

Around these targets mentioned above,the research orientation and tentative recommendations about recognition of intraformational heterogeneity in channel sandbodies are proposed by exemplification.

围绕这些目标，通过例证提出重新认识河流砂体层内非均质性设想建议和研究方向。

Channel sandbody; reservoir intraformational heterogeneity; mature oilfield; tapping potential of remaining oil

河道砂体；储层层内非均质性；成熟油田；挖掘剩余油潜力

The intraformational heterogeneity controls and affects the swept volume of the injectant in single sand layer, directly determines the waterflood efficiency, and is the key factor influencing the distribution of the remaining oil.

为此采用了细分开发层系、分层注水、开展流动单元精细研究等地质和开发措施，可以有效地降低各类非均质性对油藏最终采收率的影响。

And after analyzing the heterogeneity of sand body, point the minor channels, especially, have important influence on the intraformational oil-flooding direction, forming and distribution of remaining oil because of their function as barrier, breaking fluid and poor permeability in fluvial sand body.

通过非均质性研究，进一步揭示了单一河道砂体内部非均质性，特别是次分流河道砂体的分布，在河道砂体内起到遮挡、阻流、特低渗透等作用，对层内水驱油方向、剩余油形成与分布具有重要影响。
