The objectives of this study were to develop a wireless sensor network technologies for agrometeorological disaster early alarm system and processing system. In this study, the foehn with a high temperature and low humidity has been monitored. The wireless sensor acquisition module ZigBee has been used to monitor the climate conditions combined with a GPRS wireless transmission module to construct wireless disaster alarm sytem. Graphical programming computer software package LabVIEW 8.2 was used to develop the control and monitoring systems.

本论文研究目的旨在发展气象灾害预警及处理系统，以焚风灾害为研究对象，焚风为台湾农业气象灾害之ㄧ，每年发生次数频繁且不可预测，当焚风发生时，监控焚风产生的高温和低湿变化，透过ZigBee无线传输技术，可连结温湿度、光度及土壤含水率等感测器，并与GPRS模组结合，将资料即时传送至伺服平台，藉由LabVIEW程式监控环境变化，达到气象环境即时监测之目的。

Based on the rich historical soil and macrostructure of society, this thesis draws from the perspective of sociology on Lucien Goldmann's sociologictheory on novels-happenstantialistic structuralism, chooses structure as the key point of tangency with respect to the change of viewpoint following the sociologic imagination, andthus focuses on the interpretation of sociology on both the Chinese and Western novels by analyzing the social spirits and cultural spirits. From the standpoint of successive longitudinal happenstantialism and conexisting horizontal structuralism, the thesis also endeavors to understand and interpret the complicated relationship between novel structure and spiritual structure of sodiety from the external to the internal, thus systematically illustrates the deep relationship between novels and society.

论文将小说置于社会学视野内，立足深厚的历史土壤，依据宏观的社会构架，发挥社会学的想象力，借鉴吕西安·戈德曼"发生学结构主义"小说社会学理论，选择"结构"作为遵循社会学想象力进行视角转换的重要切入点，着重从社会精神和文化精神的层面对中西小说进行社会学的阐释；在历时纵向发生学和共时横向结构主义的视阈中，由此及彼，由表及里，"理解"和"解释"小说结构与社会精神结构间的复杂关系，进而系统地阐明小说与社会的深层关系。

The planting condition and the nutritious component of samphire were studied after its introduction into yancheng, and the results showed that its main nutritious component had no diversification though the planting condition and the component content had changed slightly due to the altering of climate, the soil and so on. Further more, several nutriment's content had been increased.

通过比较北美海蓬子和盐城海蓬子在生长条件和营养成分的差异，发现北美海蓬子引种盐城滩涂后，虽然由于气候、土壤等条件发生了变化使其栽培条件和各营养成分的含量发生了一定的变化，但是其主要营养分组成却没有变化，而且改良后的品种某些营养素的含量得到了提高。

Invasion of Spartina grass has induced significant decline of the soil ecological properties of the wetlands.

米草入侵后土壤的各项养分指标均有明显下降，湿地土壤生态化学性质发生了明显的退化。

Unconsidering the effects of soil erosion, the annual variation of the SOC stocks of Yujiang County was +8.63107kg.

在没有土壤侵蚀发生的情况下，余江县土壤有机碳库年度变化量为8.63×10~7kg，变化率为+2.45％。

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。

The roots of spring-sown maize and summer-sown maize could touch with each other in relay-planting system, which made the roots competed for water and nutrition. Thus, more of the water and nitrogen in those soil layers were used, which led to the decrease of water and nitrogen in those soil layers.

玉米根系数量和TTC还原总量在剖面分布上均发生交叉，春、夏玉米间存在养分与水分的竞争，使根系所达到的区域土壤养分和水分利用量增加，从而使相应土层土壤全氮含量和水分含量下降。

The results showed that flooding significantly increased the content of amorphous iron oxides and P adsorption capacity accompanying with a sharp decrease of crystalline iron oxides and P desorption in two tested soils.

结果表明，淹水使土壤中结晶态氧化铁含量明显减少，无定形氧化铁和土壤对磷的吸附量急剧增加，磷解吸下降；落干则使之发生相反的变化。

The results indicated that the surface salt contents in the spring of 2006 were the highest among the three samplings, the surface soil salt contents declined from spring to summer of 2006, and the change of surface soil salt contents was not obvious from summer to autumn/winter of 2006. The variation of surface soil salt contents was related to rainfall greatly.

土壤盐分浓度的变化与降雨量有密切关系，虽然2006年降雨偏多，但佛山市南海区农业集约化水平较高，部分菜地连年种植蔬菜、复种指数极高、化肥施用量偏大，从而在遇到干旱年份和季节，集约化露天菜地土壤仍有发生次生盐渍化的风险。

This simulation system will help to improve innovation design level of high-speed cultivation machine such as high-speed plow and high-speed rotary tiller. SPH; back-rotary tilling ; simulation ; soil-tool interaction ; high-speed cutting

因为牵涉到多相、松散和物性分散的耕作土壤在工作部件高速作用下的破坏过程以及破坏后土壤运动状态的描述，用连续体力学理论及其数值解法(有限单元法或者边界元法)很难描述该过程如有限单元法在大变形状况下会发生网
