Seen from the functional group, perennial grasses and forbs had stable compositions, but compositions and number of shrubs, half shrubs, small half shrubs, annuals and biennials were unsteadiness, where aboveground biomass in warmed plots was much difference with control. Nitrogen addition may enhance aboveground biomass obviously from latter growth stages.

施用氮肥的效果在植物生长后期才明显的表现出来，施氮样地地上生物量明显提高；增温和施氮作用使地下生物量发生了一定变化，但无显著差异；通过多元逐步回归发现，影响植物群落地上生物量和地下生物量最显著的因子是10-20cm土层的土壤湿度。

Methods: The minimum inhibitory concentrationof Xipayiguyiy on P.gingivalis,P.intermedia and F.nucleatum was observed by agar dilution in vitro.Also,the effects of Xipayiguyinye on oral malodour challenged by cysteine was investigated on 10 volunteers in vivo.Results: It showed in this study the MIC of Xipayiguyiy for Pg and Fn was 1mg/mL,and for Pi was 0.5mg/mL.It was also found the Xipayiguyinye achieved significant effects on oral malodour challenged by cysteine.

采用琼脂稀释法，测定西帕依固龈液对牙龈卟啉单胞菌（Pg、中间普雷沃菌、具核梭杆菌的最低抑菌浓度；对10例志愿者采用自身前后对照试验，观察四种干预措施（无干预、清水、西帕依固龈液、口泰）对半胱氨酸激发性口臭的最大值水平、各时间点下降百分比及口气值的下降曲线的影响，评价西帕依固龈液防治口臭的效果。

Walking against the wind, in the water,while wearing a backpack burns about 50 more calories per hour than walking with no resistance. People who wear pedometers also tend to burn more calories and lose more weight.

逆风行走，逆流而上或背上背囊相比那些步行无风阻的人，每小时会燃烧约多50卡路里的能量，而那些身背计步器的人往往燃烧更多的卡路里，减肥效果更明显。

Microfiber Products detail: Microfiber refers to the so-called 0.4uM of the micro-diameter fibers, its fiber silk degrees only 1 / 10 special wedge-shaped cross-section to enable it to more effectively capture even a few microns of dust particles, decontamination, to oil the effect is very obvious. 75:25 of polyester / nylon ratio, making material is extremely soft, on the swab surface without any harm, even in the field of high precision, such as lens coating, large scale integrated circuit manufacturing process can also be assured that the use of its water volume, water absorption speed is ordinary cotton fabric for more than 5 times.

所谓超细纤维是指直径0.4uM的微纤维，其纤维度仅为真丝1/10特殊楔型横截面，使它能更有效地捕获甚至几微米的尘埃微粒，除污、去油的效果十分明显。75：25的聚脂/耐纶比，使得质料极其柔软，对被拭物表面无任何伤害，即使在高精密领域里如镀膜镜头、大规模集成电路生产过程中也能够放心使用，其吸水量、吸水速度是普通棉织物的5倍以上。

In addition, neutrophils from mice that were raised in a germ-free environment or on antibiotics were likewise diminished in their immune responses, but this effect was not permanent: Re-exposure of these mice to a conventional environment (that is, one containing normal bacteria) restored immune function.

并且，在无菌条件下或者使用抗生素条件下的中性粒细胞升高，都伴随着免疫反应的降低。但这种效果并不是永久的：将小鼠重新暴露于含有正常细菌的正常环境中可以使其恢复免疫功能。
