干旱

The research object of this thesis is Momoge wetland, which is the largest one in the droughty area of western jilin province.

莫莫格湿地处于吉林省西部干旱地区，东北科尔沁沙地边缘，是该区域面积最大的湿地区，对防止沙化，地域性水源涵养，气候调节，具有重要作用。

The enzyme activity of the antioxidation system of xermorphic shrubs in Inner Mongolia West Erods region was studied. The extent of lipid peroxidation is not higher, but SOD POD CAT activity is different in different vegetation,which illuminates different vegetation has different adaptive mechanism to the droughty environment.

对内蒙古西鄂尔多斯荒漠区强旱生小灌木抗氧化酶系统的研究发现，它们的膜脂过氧化程度都不高，但体内SOD、POD、CAT的活力表现不同，说明不同植物对于干旱的环境条件具有不同的适应机制。

AbstractLocated in droughty and windy desert region of south edge of Tarimu basin, the Hetian oasis of XinJiang, is extremely frail for its ecological environment.

位于塔里木盆地南缘干旱及风沙区的新疆和田绿洲，生态情况极其脆弱。

Located in droughty and windy desert region of south edge of Tarimu basin, the Hetian oasis of XinJiang, is extremely frail for its ecological environment.

位于塔里木盆地南缘干旱及风沙区的新疆和田绿洲，生态环境极其脆弱。

When drilling with the new water-saving technology, the surface water almost will not be consumed, the strata not be disturbed and the drill penetration rate can be enhanced greatly, showing a nice future applied in droughty and water lack area.

该节水钻探新技术在钻进过程中基本不消耗地表水，且不扰动地层，并能显著提高机械钻速，在干旱缺水地区具有广阔的应用前景。

The main limitation element that climate drought and edaphic barren are development of production of Shanxi province agriculture all the time.

气候干旱和土壤瘠薄一直是山西省农业生产发展的主要限制因素。

The proposals include building the Lom Pangar Dam further up the Sanaga river from Nachtigal to ensure steady water supply to hydropower plants downstream during the dry season, as well as expanding the country's main port at Douala and building a new road linking the port to the Edea factory.

该项目包括建立Lom Pangar大坝以确保在干旱季节为下游的水力发电厂提供稳定的水力供应，并扩建喀麦隆的杜阿拉港口并修建从Edea工厂通往港口的道路。

The seedlings of six wild species in Elymus were treated with drought stress, and their height, MDA, proline, and chlorophyll content were investigated.

采用干旱胁迫处理不同来源的披碱草属六种野生牧草幼苗，对其生长高度、相对含水量、丙二醛、脯氨酸和叶绿素含量进行测定。

It also occures in cold weather because the permeability of the endodermal cells decreases rapidly below 5℃, so the root resists the entry of water.

在寒冷的季节也同样会发生生理干旱。因为在5℃以下时内皮层细胞的渗透性迅速降低，因此根会抵抗水的进入。

We used maize seedlings (Zea mays L.) and tobacco (Nicotiana plumbaginjfolia L.) as material. In the first section, we have investigated cold- shock-induced chilling, drought, heat and salt stress resistance in maize seedlings. In the second section, by modifying the Ca~ and CaM levels, we have tried to establish the involvement of calcium messenger system in the cold-shock-induced cross adaptation. In the third section, we have tried to establish a transgenic tobacco system expression CaMICaMIBP genes, so that the others can use it to investigate the process of physiology and biochemistry which endonuclear and cytosolic calmodulin have taken part in.

以玉米幼苗和烟草为实验材料，本文第一部分通过将玉米幼苗进行短期冷驯化后对冷胁迫、干旱胁迫、热胁迫及盐胁迫的影响，试图证明玉米幼苗中交叉适应现象的存在及其机理；第二部分通过外源修改Ca~(2+)和CaM水平，研究了钙信使系统在交叉适应现象中的可能作用；第三部分通过建立诱导性表达CaM/CaMBP转基因烟草体系，便于研究受细胞质CaM和细胞核CaM调控的各种生理生化过程。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
