虽然近十年来现代医学在男性不育症的治疗有了长足的进步，ART大大增加了无精子症和高度少精子症病人生育的可能性，但是自然的妊娠还是人人所期望的。

First:ecology mode:to establish protection field in patria and protect,supplementary and recovery the biogeocoenosis and natural germ,in order to increase the output.

一 生态化生产：在冬虫夏草原产地建立保护生产区，完全利用产地自然条件，通过对生态环境和天然菌、虫资源的保护、补充和恢复，增加天然冬虫夏草的产量。

The change of landuse patterns in 1977-1998 shows indirectly the desertified land had been restored and is being restored. The relationship between landuse patterns and soil types was also analysed in this paper, from 1977 to 1998, the areas of rangeland and mobile sand dunes decreased in most soil types and the areas of woodland, shrubland and farmland increased, which means that the modification of landuse patterns due to limitation of soil types will be helpful to desertification control.

同时土地利用格局的时空变化与土壤类型间关系的分析表明，1977-1998的20余年间，在四种主要土壤类型上各种土地利用类型的变化具有一定的规律性，草牧场和流动沙地的面积基本上呈减小的趋势（分布在风沙土上的草牧场面积除外），而乔木林地，灌木林地和农地面积均为增加的趋势，这说明在土壤类型这一土地自然属性的严重制约下，人们被迫调整其土地利用格局，从而有效地遏制了荒漠化的发生和发展。

Certain staphylococcal species are regularly found in 'naturally' processed meat products, which are produced without addition of starter cultures.

某些葡萄球菌种经常发现在'自然'加工的肉类产品，是没有增加生产的发酵剂。

Three expression vectors containing mutant gfp which were truncated from 3′ termine were constructed in the present paper.The mutation gfp with different length under the control by T 7 promoter were expressed in E. coli BL21 cells.

本文将突变型 gfp3′末端不同程度地截短，构建成表达载体，在大肠杆菌 BL 2 1中表达了不同长度的绿色荧光蛋白，当其生色基因中 65位 Ser点突变成 Thr，则 GFP的激发波由 396nm增至 4 70 nm，不用 UV激发，仅在自然光源下就可看到强烈的绿色荧光，发光强度增加 6倍，若从 3′端截短 12个氨基酸密码，对发光无影响，但截短 75个氨基酸密码，则激发波长降到 360 nm，发光强度减少 12倍。

In 1980s, the rural tourism which emerged in our country, is the satisfaction for the city people to return the nature, the leisure entertainment as well as convalesces the body and mind demand, also is developed to prevents the agricultures the village to decline and increases the countryside income the effective method.

A greened roof is a natural air-conditioning,the roof is greened by theranspiration of the plants and the transpiration in green roof to increase air humidity, lower ambient temperature, reducing heat radiation, thus easing Heat island effect of the city .

一个绿化屋顶就是一台自然空调，屋顶绿化通过植物的蒸腾作用和屋顶绿地的蒸发作用，增加空气湿度，降低环境温度，减少热辐射，从而缓解城市的局部热岛效应。

Furthermore, as the oscillating frequency of the cylinder approach the natural vortex shedding frequency, because of the phenomenon of resonance in the channel flow, and the heat transfer rate is enhanced more remarkably.

此外，当圆柱振动的频率接近流场的自然振动频率时，会与管道内的流体产生共振的现象，此现象能够大幅的增加流体的扰动，并且扰乱管道内的流场以及温度场，产生较佳的热传增益。
