When data are balanceable, two methods should have no difference, but the standard error computed by two-level model is bigger than that by generalized estimating equation. When data were unbalanceable, generalized estimating equation shows somewhat advantage. Type 2 diabetes mellitus might exist genetic heterogeneity and there is no gene that is related with the occurrence of bipolar disorders.

当数据平衡时，两者结果一致，但多水平模型计算出的标准误大于广义估计方程算出的标准误；当数据不平衡时，两者结果不一致，广义估计方程更能检测出有统计学意义的基因位点。

By lifting the 'unconcealment' from the 'concealment', the essential truth of art ontology reveals itself. Therefore we have chosen Obstruction as title of this exhibition, since the real question that should preoccupy art events is the presence of heterogeneity.

而在这种关系中，艺术活动的真正价值即是不断地反思既定的表征实践，让世界在表征的遮蔽中闪现出无蔽，这正是艺术在本体论视域中的真理性。

Aspect, rather than spatial scale, had the largest impact on undercanopy light. In forests with rough topography, utilizing transects that run from the ridge to the valley is more likely to adequately characterize spatial heterogeneity than plots or a few longer transects.

在福山试验林，坡向较空间尺度对林下光照有更大的影响，因此在地形起伏剧烈如福山试验林的地区，利用多条由稜线延伸至溪谷的样线，比少数几条绵延甚长的样线或样区更能充分涵盖空间的异质性。

The results show that mechanical heterogeneity has great influence on the J-integral of welded joint containing transverse crack. The J-integral on the path cross the interface between welded joint and base metal is higher than the J-integral on the paths in the weld metal for undermatched joint,while the J-integral on the path cross the interface between weld metal and base metal is lower than the J-integral on the paths in the weld metal for overmatched joint. Moreover,the difference of J-integral values increases with the increasing of the load and strength mismatching difference and the path-enclosed length of interface between weld metal and base metal.

计算结果表明：力学不均匀性对含横向裂纹焊接接头的J积分有重要影响，低匹配焊接接头中积分路径穿越焊缝与母材界面的J积分值高于积分路径在焊缝内的J积分值，高匹配焊接接头中积分路径穿越焊缝与母材界面的J积分值低于积分路径在焊缝内的J积分值；载荷越大，焊缝与母材的强度差别越大；积分路径中包含的焊缝与母材界面长度越大，J积分的差值越大。

The generating reason,response characteristic and distributing rule of remaining oil was deeply studied aiming at water-flooded continental reservoir with characteristic of intense heterogeneity,high water-cut,low recovery efficiency,complex distributing rule of mobile remaining oil,intergrowth of major and untabulated formation . At the same time,a systemic method of evaluation and predicating remaining oil and pressure was put forward basing on the theory of development geology,seepage flow mechanics,fluid mechanics which resolved the hard technologic problem of predicting remaining oil and pressure.

本文针对陆相注水开发油藏具有非均质性强、含水率高、原油采收率低、可采剩余油分布复杂、主力产层和表外产层同时存在等特点，深入研究了剩余油的形成机理、响应特征和分布规律，应用开发地质学、渗流力学、流体力学和地质统计学理论，将静态地质数据和动态开发数据相结合，综合现有的与剩余油及压力分布有关的所有资料，提出了一套系统的评价和预测剩余油及压力的方法，较好地解决了目前剩余油与压力评价和预测中的技术难题。

The analysis result shows that the remaining oil of this area is characterized as: Remaining oil is mainly distributed in thin tabulated beds and untabulated beds with low permeability. Remaining oil scatters widely. Complexity exists in the contact between remaining oil and water flooded layers and zones. Vertically, the remaining oil layers in adjusting area alternates with water breakthrough layers, between them the barrier beds is thin. Horizontally, because of the plane heterogeneity, the relatively good intervals are flooded, so that the remaining oil only exists in margin oil layer owing to faultiness of injection-production; remaining oil is enclosed by waterflooded zone, therefore, it is so complex relationships between remaining oil and waterflooded layers and zones that high requirements are made in the choice of completion optimization.

通过研究分析，研究区二类油层剩余油具有以下特点：(1)剩余油以表内薄差层和表外层为主，渗透能力低；(2)剩余油比较零散；(3)剩余油与水淹层和水淹带的接触具有复杂性；调整区剩余油从纵向上看，剩余油层与见水层相间分布，隔层小；从平面上看，由于油层平面的非均质性，相对较好部位已水淹，只在油层的边边角角部位由于注采不完善等因素存在剩余油，剩余油被水淹带包围，所以目前剩余油与水淹层和水淹带的接触相当复杂，这对完井方式的选择提出更高的要求。

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。
