How then to solve contradictory this, the lamination teaching is one good means.

那么如何解决这一矛盾呢，分层教学不失为一种好的办法。

According to the result, the confidence region of unknown parameters in single-index models is constructed. Finally, we consider the test of correlation and heterogeneity for hierarchical nonlinear mixed-effects models. According to Laplace approximation expansion of integrated log-quasilikelihood, a class of score test statistics is proposed. Under some very mild conditions, we prove the asymptotic distribution of the test statistics is a standard X~2-distribution. Through a Monte Carlo simulation study, the finite sample performance is examined.

最后，我们研究的第四个问题是分层非线性随机混合效应模型的相关性与异方差性检验问题，依据对数拟积分似然的Laplace近似展开提出了检验统计量，在一些正则条件下，得到了检验统计量的渐近分布是一个标准的χ~2-(来源：d7d7A65BC论文网www.abclunwen.com)分布，通过Monte Carlo模拟研究了其小样本的表现，实例验证了其实际应用。

The reconstruction of large chest wall defect should be required divided management according to the location, region and degree of the defect. There are different flaps for covering soft tissue defect. Latissimus dorsi muscle flap with many advantages is the first choice.

结论巨大胸壁缺损需要分层修复，胸廓缺损可以用鈦网或聚丙烯网片修补，软组织缺损需要根据缺损部位、大小和范围及周围组织情况选择不同的修复方法。

When thinking of a system in terms of layers, you imagine the principal subsystem in the software arranged in some form of layer cake,where each layer rests on lower layer.

当我们说一个系统是分层架构的时候，你可以把这个软件想象成一个有很多层的蛋糕的样子，其中每一层放在它的下一层上。

Methods 265 cases gathered from multi-centric clinic were studied through layerage and cross-section by using the method of data mining such as free-scale-networks, and so on.

采集来自多中心的临床病例，运用无尺度网络等数据挖掘方法对其进行分层、横断面研究。

Cognition disturbance and allolalia were the chief clinical manifestations. The imageology showed that the impairment involved occipital lobe and temporal lobe most. 17 cases presented red-ragged-fibres and parking lot-like ultrastructure in 3 cases. Brain biopsy showed layerage structure. There were 15 of them carried mtDNA A3243G mutation. Conclusions MELAS Syndrome usually involved central nerve system and skeletal muscle.

主要临床表现为认知功能障碍及言语障碍，头颅影像学检查示枕叶、颞叶脑回受累为主。18例行肌肉病理检查显示17例存在破碎样红纤维，3例行肌肉电镜检查发现线粒体堆积呈停车场样排列，3例脑活检示病变皮层组织呈分层样改变，15例发现mtDNA A3243G点突变。

If you value more highly to learn Chinese in China, the advantages are layered and helpful.

如果你的价值更高，了解中国在中国的优势是分层的，有益的。

In the second chapter, it proposes a layered planning method based on surface of minimum risk.

本文在第二章中介绍了一种基于最小威胁曲面的分层规划法。

Detailed, and a layered control system was put forward.

并给出了仿生水下机器人的分层控制系统。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
