However, the fact is that by now those research that studies international tourism in China far lagged behind the remarkable development of China's tourism, especially how to construct a foundationally theoretical basis for our research work, so that make our research outcome endowed with more practical values.

然而，与我国旅游服务贸易迅猛发展不相符合的是迄今为止我国有关旅游服务贸易方面的研究大大落后于旅游业进一步发展的需要，尤其是如何为国际旅游业的研究构建一个坚实、规范的理论基础，使得我们的研究成果具有更大的应用价值是研究过程中亟需解决的问题。

From the study in the past, the experts in and out of our country studied the music of Gesar, but they merely studied the music noumenon on some part or some area fragmentarily. So this article tries to probe into its music thoroughly, using the inner regulation of this art and the forms it embodies. The first chapter of the thesis introduces the talking and singing in Gesar, with theemerging and development of the combining of the two art forms being a start.

从以往的研究来看，虽然国内外也有些专家、学者对《格萨尔》音乐有一定的研究，但他们的研究都是零碎性的、片段性的，更多的是对某一部分、某个地区的音乐本体研究，所以本文将试着从它的艺术形式出发，以这种艺术形式的内在规律及其特殊的表现形式来对《格萨尔》音乐进行一个较为全面和深入的探讨。

This kind of reform includes: Researching object field, the research that produces an impact by the opposite in the past turns into the research to producing kind; On the structure, by the past " 3 chunk " turn into an organic whole; On content, by grumous in the past doctrine history the illuminate of the fundamental that colour turns into to move to economy and basic rule; On the method, bold the scientific effective method in drawing lessons from western economics, the analytic research technique that makes us traditional gets plenitude.

这种改革包括：在研究对象方面，由过去的对生产关系的研究变为对生产方式的研究；在结构上，由过去的&三大块&变为一体；在内容上，由过去浓厚的学说史色彩变为对经济运行的基本原理和基本规律的阐释；在方法上，大胆借鉴西方经济学中科学的有效的方法，使我们传统的分析研究方法得到充实。

These compounds are of substantial interest both inviewpoints of theory and practical applications, mainlyunder the stimulus to achieve synthetic models either foractive sites of iron-sulfur proteins or for transitionmetal catalysts. This thesis describes the synthesis, structures andconformations of 51 new iron-sulfur cluster complexes,which have been characterized by elemental analysis andstandard spectroscopic methods. In addition, single-crystalX-ray diffraction analyses were performed for 4 representa-tive new compounds. Reactivities of μ-〓 with mono- and di- Grig-nard reagents derived intermediates toward various organicelectrophilic substrates were studied, along with complexa-tion of arynyl-containing iron-sulfur clusters by 〓Thus, several bridged, non-bridged, monomeric, dimeric,homonuclear, heteronuclear iron-sullfur and iron-sulfur co-balt-carbon cluster complexes were synthesized. A novelreaction and convenient route for the synthesis in highyield of tetranuclear iron complexes 〓 containing atetracoordinated sulfur atom was discovered, whereas aplausible mechanism based on experimental results was propo-sed for the formation of the new cluster type.
