Now China possesses 31 World Heritage and can be listed the third in the world. But only 1/4 World Heritage is natural heritage or dual heritage, which is unconsistent with Chinese successful development in World Heritage protection. The application projects for World Heritage List are lessening now in China; Keynes Decision and Suzhou Decision has raised the standard of World Natural Heritage; INCN and ICOMOS are enhancing valuating and supervising systems; conflicts between utilization and conservation have arised due to different interests holders.
但自然遗产和双重遗产只占全部世界遗产的四分之一,这与我国日益壮大的世界遗产事业很不相称,也与世界上其他国家自然遗产属性具有趋同性;从我国现有的世界遗产预备清单及未来十年政府申报计划可看出,可申报自然遗产项目还在萎缩;《凯恩斯决议》、《苏州决定》在制度上提高了世界自然遗产的准入门槛;IUCN、ICOMOS等相关组织对世界自然遗产的评估和监测机制正在加强;不同利益主体的博弈人为加剧了我国世界自然遗产开发与保护之间的矛盾。

Patent, and then the blade-to-blade flow was computed by solving the two-dimensional steady Navier-Stokes equations, finally, overall performance and internal flowfield characterization were obtained and analyzed.2. As to radial matching between blade sections, preliminary investigations were developed from three aspects such as stall margin customizing technique, control technology of tip clearance flow, prediction model and control technology of corner separate.a On basis of reviewing on methods of achieving the goal of stall margin in design process of fan and axial-flow compressor, in conjunction of understandings on "Sweep/Dihedral", stall margin customizing technique was put forward; two-dimensional performance prediction method for stall margin customizing was developed, it can consider influences of radial stacking patterns of blade sections and axial distances between blade rows conveniently and rapidly.b A simple model for tip leakage mixing loss of unshrouded blades for compressible flow was presented.

Under the background of digital DEM of maor mountain area, and through the program of Avenue in Arcview, the result of potential ravine highly inosculates with the real ravine. With the comparison of potential ravine and real ravine, it can reflect the developing tendency of ravine in this area. Through positioning with GPS and investigation in this area, we can divide the potential ravine of this area into three forms, that is parallel ravine area steep ripe ravine area and evenness swamp area. It can provide scientific reference for forest management and tree planting, and it is a new theory to prevent soil and water loss, and carry through the ravine controlling by people.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称;三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起,称之为挽歌体诗人或者史诗诗人,他们被称为诗人,似乎只是因为遵守格律写作,而非他们作品的模仿本质。
