Hierarchical linear modeling is the most frequently used technique for analyzing multilevel data. In this paper, the twelve key issues in multilevel research and/or using HLM software were reviewed, and provided their exact meanings and feasible solutions. The 12 key issues included intraclass correlation coefficient, sample sizes, formation of organizational constructs, centering problems, fixed effect and random effect, estimation methods, goodness of fit index, explained variation, multicollinearity, robust standard error, level one variance equation, and empirical Bayes estimates.

本文针对阶层线性模式在多层次研究上有关於技术、测量与方法论所遭遇的问题，进行文献整理并讨论其实务意涵，并依据使用时机、抽样议题、资料汇总、分析方法、与模式评估与估算等五方面整理出十二项重要议题与解决之道，包括：组内相关系数的意义与判断准则、多层次研究各层的样本数问题、变数聚合成组织层次问题、中心化的意义、固定效果与随机效果的设定、估计法的选择、适配度的比较、解释变异量的计算、多元共线性的分析、强韧性标准误、第一层误差项变异数与实证贝氏估计值的运用。

And the key is to take advantage of the physical and chemical properties of shale or mud to enable the shale or mud to form a semipermeable membrane or form a high quality partition membrane on the wall of the well, so as to prevent the mud from flowing into the formation to effectively stabilize the wall of the well and protect the reservoir.

水基钻井液成膜技术是当今研究的热点，其核心技术是利用页岩或钻井液的物理、化学特性，使页岩或钻井液具有半透膜的性能或在井壁上形成一层较高质量的隔离膜，阻止钻井液向地层的进一步滤失，从而有效地稳定井壁和保护油气层。

The single piy paper can be slit and rewinded into two ,three or four ply paper with variious specifications,for the production of napkins, hankies, facials or sanitary napkins.

从单层复卷分切成双层、三层或四层规格不同的盘纸，供折叠纸巾、餐巾、盒装面巾、卫生巾等使用。

By that time he had suffered four cases of stomach bleeding and his skin disease was so bad that no medicine had any effect. The only way to treat it was to "spray-paint" the medicine on layer by layer.

在那以前，他的胃已严重出血四次，可怕的皮肤病更是恶化成了药石罔效的顽疾，唯一的对治法，是在溃烂的部位「拷漆」，一层一层地把药涂盖上去。

The correlation of hydrocarbon accumulation and major control factors between these two basins indicates that there exist premium source rocks and reservoirs in subsalt carbonate rocks of Cambrian in these basins, and regionally distributing gypsum-salt rock of Middle Cambrian is good cap rock.

通过油气成藏要素及其主控因素的对比研究发现，塔里木盆地和东西伯利亚盆地在寒武系盐下都发育了优质的烃源岩和储集层，而区域性分布的中寒武统膏盐岩是良好的盖层。
