How can we best assimilate the new civilization of the modern world in such a manner as to make it congenial and congruous and continuous with the civilization of our own making?

在令大多数中国人长期困惑的中西文化的关系问题上，胡适认为关键的问题是，如何能使中国文化与看来同自己的固有文化大不相同的现代世界新文化泰然相处，并怎样以最有效的方式吸收现代的新文化，使它能同我们的固有文化相一致、相协调和继续发展。

Analysis of dynamical simulation data shows as follows: Wheel tread LMA is able to satisfy the requirements of the 300 km/h~350 km/h high-speed wheel-rail technology, and wheel tread XP55 is able to reach 250 km/h~300 km/h; the main issue of Wheel tread LM is that the larger equivalent conicity may cause the bigger lateral wheel-rail force, and wheel tread S1002 has the severe problem of harmful wheel-rail wear.

动态仿真数据分析表明：LMA型车轮踏面可以满足300 km/h~350 km/h高速轮轨技术要求，而XP55型踏面则可以满足250 km/h~300 km/h速度的要求；LM型踏面的主要问题是等效锥度比较大，从而造成轮轨横向力也比较大，S1002型踏面对轮轨存在比较严重的有害磨耗问题。

However, the consistency of theoretical promise and principle of the environmental sociology is the fundament of its research.

就这个目的，本文的研究虽然一定程度上在实证研究中对环境社会学的理论承诺和理论原则进行了表述，但是，环境社会学的理论承诺与理论原则的一致性问题是其研究的根基所在，本文只是给出了一种对此进行实证研究的可能途径，而在理论领域和实践领域此问题还有待进一步的研究。

A logicaldomain is used as a reference and the mesh movingis implemented according to an appropriate domain transformation.With sometraditional moving mesh methods,the meshes in physical domain may be tangled.To avoid this,the transformations are constructed based on harmonic mapping.Agood feature of the adaptive methods based on harmonic mapping is that existence,uniqueness and non-singularity for the continuous map can be guaranteed fromthe theory of harmonic maps.

在移动网格方法中，需要引进一个逻辑区域作为参考，网格的移动往往通过一个区域变换来实现，网格可能发生缠绕的问题是移动网格方法中一个一直没有解决的问题，我们利用调和映射来构造区域间的变换，使得变换的存在唯一生有了理论的保证，这就为避免网格缠绕打下了基础。
