When the special assignments are enforced, for example the cases of withstanding disasters and emergencies, MANET can quickly build up the network and provide distributed network especially in military affairs. In addition, during the telecommunications MANET can make the other nodes as relay stations in especial environments of the zones of mountains and hungriness where UMTS can not work on.

在特定的任务下，比如抗灾抢险、军事突击行动中，该网络能够提供分布式系统，并且其网络搭建速度快；在山区或荒漠地带，蜂窝通信无法覆盖的情况下，该网络能够以网络中的一些节点作为中继节点，转发分组，实现节点之间的通信。

It was concluded that:① soil deflation rates, at any certion wind velocity, decreased exponentially with the increase of G d ;② the effects of gravel mulch restraining soil deflation under 5 experinced gravel spread patters, at a certain G d , follow a order of Parallel strip spread

在一定的风力条件下，吹蚀速率随砾石覆盖密度的增加呈现指数递减变化；在一定的铺压密度下，不同铺压方式表现出不同的吹蚀抑制效应，从小到大依次是：平行条带铺压＜簇状铺压＜斜交条带铺压＜垂直条带铺压＜随机铺压。

In this experiment, there was no significant difference between R and H treatment. The soil pondage of Z treatment was less than that of R and H, which indicated that Z treatment was disadvantageous to soil water infiltration under irrigation conditions because Z was covered by straw and had high density.

模式之间比较，旋耕和耙耕模式土壤贮水量差异不显著，免耕模式小于旋耕和耙耕模式，表明在灌溉条件下，免耕模式由于地表秸秆覆盖加之土壤表层容重变大，不利于土壤水分的下渗。

The differentiation states of costae indicates the ways they absorb and transport water, and their ability adapting to the dry conditions, which was elucidated by the following examples: Brachythecium plumosum, because of its thin cell-walls in the costae and the absence of hydrome, assistant and steroid cells, can absorb water and nutrition under shady and moist conditions; Plagiomnium rostratum, though often grows in shady and wet condition, has hydrome and steroid cells, a feature similar to those of xeric mosses, which endows it to grow in the conditions with periodical drought stress during its life cycle; Hygrohypnum luridum is characterized by its slender leaves with only one layer of cells, the thin cell-walls, the absence of filaments on the leaf surface, and the fewer layer cells in the costae, the absence of hydrome and steroid cells. These features make it adaptable to aquatic environments. For Pogonatum inflexum and Atrichum undulatum, their ventral surfaces covered with lamella, while for Racomitrium japonicum, Thuidium cymbifolium, Macromitrium ferriei, Diphyscium fulvifolium, Barbula unguiculata and Ceratodon purpureus, their leaves are strongly mammillose or papillos. Such appendiculate structures made them adaptable to thy conditions.

例如，荫湿生环境下的羽枝青藓Brachythecium plumosum，其中肋细胞胞壁较薄，无导水主细胞和副细胞的分化，也没有厚壁细胞分化，能够在阴湿环境下吸收水分和养分；钝叶匍灯藓Plagiomnium rostratum具有与旱生藓类植物相似的中肋结构，叶片较厚，中肋具导水主细胞，中肋背面具厚壁细胞，这些特点使该种藓类植物能够分布于间隙性干旱胁迫的环境中；水灰藓Hygrohypnum luridum叶片纤细柔弱，仅1层细胞，细胞胞壁薄，叶表无附属结构，中肋细胞层数少，无导水主细胞分化，也没有厚壁细胞，这些特点使得水灰藓'能够生长在水生环境中；东亚小金发藓Pogonatum inflerum和波叶仙鹤藓Atrichum undulatum的叶腹面覆盖着栉片，东亚砂藓Racomitrium japonicum、大羽藓Thuidium cymbifolium、福氏蓑藓Macromitrium ferriei、东亚短颈藓Diphyscium fuhifolium、扭口藓Barbula unguiculata和角齿藓Ceratodon purpureus的叶片表面有乳头状突起或疣状物，这些附属结构使它们能够适应于旱生的环境中。

In the A and B figures, small grape-like tissue covered over all the epiglottic area that is hypertrophic lymphoid tonsil. More advanced the fiberoptic laryngoscope during spontaneous inspiration phase, larynx and vocal cord can be visualized in the C and D figures. We must emphasize that endotracheal intubation and even artificial ventilation was hardly performed under direct laryngocopy and general anesthesia.

图片A和B中，覆盖整个会厌部的葡萄息肉状物就是濔漫增生的舌底部淋巴组织增生，当光纤内视镜随著病人自主呼吸向内向下移动，吐气时可以见到图片C和D中喉头及声带的开合，由於在全身麻醉下无自主呼吸时此病人咽喉部位的似帘幕状遮蔽特殊结构造成之困难插管甚至是困难通气。

The results indicated that applying 105kg/hm2 nitrogen and 75kg/hm2 phosphorus fertilizer is the most economic and rational; applying 45000kg/hm2 farm manure with phosphorus as base fertilizer, two thirds nitrogen as seed manure and one third nitrogen as topdressing is more economic and rational;the best planting density is 67500 zhu/hm2, the transplanting style after growing seedlings in small arch greenhouse in early spring and the multiple cropping style after rape stubble should be extended over large areas, the multiple cropping style after wheat stubble should be extended in the southern rivers rigions of this locality.

The study was conducted in the field to have a survey of the degradation of films and examine the effect of degradable films on crop by comparing it with the uncovered plots and polyethylene films. And the laboratory experiment on the effect of different soil moistures (air-dried, 0.10 g/g, 0.15 g/g, 0.20 g/g, 0.25 g/g, 0.30 g/g) and temperatures (5℃、 15℃、 25℃、 35℃、 45℃) on degradable ratio and content of films was studied. The conclusions were as follows:(1)The film can be degradable at every treatment but its degradation was best when the temperature and water content in soil was 35℃ and

本试验统计观察了降解膜的田间降解状况，比较了它与裸地、普通膜对作物的覆盖效果，在室内研究了在不同土壤水分(风干土、0.10g/g、0.15g/g、0.20g/g、0.25g/g、0.30g/g)和温度(5℃、15℃、25℃、35℃、45℃)下，膜降解率、土壤微生物量碳等的变化情况，获得的主要结论如下：(1)地膜在各处理下都发生降解，但温度为35℃和水分为0.25g/g时地膜降解最快，程度最深。
