先不考虑协变量—儿童年龄、身高、体重的测量误差，分别就儿童的各项肺功能指标对年龄、身高和体重建立结构回归模型；然后在协变量的测量误差分布相同和不同的假设下，分别建立各项肺功能指标对年龄、身高和体重的带有测量误差的结构回归模型，从而综合估计空气污染对儿童肺功能的平均影响效应。

Intra-family comparison resulted in the findings of the four developmental stages of the indicative supplemental structure of the Tibeto-Burman group from primitive, adhesive, compound, adhesive-compound (single or no structural auxiliaries), adhesive-compound (frequent use of structural auxiliaries with syntactical value).

通过语族范围内述补结构的比较，根据各语言述补结构的特点将藏缅语的述补结构的发展归纳为四个阶段：萌芽状态的述补结构阶段，粘合式述补结构阶段，组合、粘合式述补结构阶段第一级，组合、粘合式述补结构阶段第二级(结构助词丰富，有重要的句法地位)。2、揭示汉、藏缅、壮侗、苗瑶各语族述补结构的异同及这些异同产生的机制。

With these discussions, the author concludes that given the complexity and contradiction of the architecture discipline, it is true that we may find it impossible to make a definite 'pro' or 'con' on structural correctness. But with its inherent resonance to high-resource-effiency and sustainability, structural correctness is not at all a non-sequitur in contemporary architectural critique.

作者认为，虽然建筑学本身的复杂与矛盾使我们不可能对结构正确性采取简单的肯定或否定态度，但结构正确性在资源有效性和可持续发展方面的积极意义，却使我们必须在当今的建筑学讨论中给它以一席之地。

A theory annoyance model for structural vibration serviceability design is proposed in this research on the basis of structural dynamics, reliability theory and psychophysiology methods.

本文结合结构动力学，可靠度理论和心理物理学，提出了基于烦恼率的结构振动舒适度设计理论模型，其目的是使工程结构振动舒适度的设计方法从原来的半定量设计阶段提高到定量设计、可靠度设计和优化设计阶段。
