First of all, as the forests disappeared, the propagation decreased, while some kinds of plants and animals were even close to deracination or had already died out. Next, the natural disasters, such as flood, drought, and tornado, etc. broke out more frequently and strongly. Again, without the protection by forests, soil erosion and fertility decline together with other problems appeared. Finally, forest vicissitude also had negative effect to social economy and people's lives.

首先是由于森林面积的减少，导致一些森林动植物的数量减少，濒临灭绝，甚至消失；其次，森林的变迁导致海南岛水灾、旱灾和风灾等自然灾害发生次数增加，强度加大；再次，土地失去森林的保护而引发严重的水土流失和土壤肥力下降等种种问题；最后，森林的变迁还对社会经济及人们的生活产生不利的影响。

To expand is to increase in size, area, volume, bulk, or range

expand 指在大小、面积、容积、体积或范围等方面的增长

Among it wrap up surface auxiliary that cover,-COOH,-OH, sulphur base S032~ sour hydroxyl carboxyl , etc. group last the not facilitating last aluminium the buoyancy of floatings of the powders, and C-C chain , alkyl phenyl R-C6HU fatty alcohol base fatty acid base R-COO, R-0- long in structure, etc. base group kiss not oily, base these group add , facilitate aluminium powder water build rise of area.

表面包覆的助剂中，羧基-COOH、羟基-OH、磺酸基SO_3~(2-)等集团是亲水性的有助于提高铝粉的漂浮力，而C-C结构长链、烷基苯基R-C_6H_(14)脂肪醇基R-O-、脂肪酸基R-COO~-等基团是亲油性的，这些基团的加入有助于铝粉水盖面积的提高。

Dong Feng county pushs policy of rural industry structural adjustment actively, below the premise of crop of main stable grain, according to the demand of benefit and market, each villages and towns enlarged the area of the economic crop such as melon dish, oil plants, beet, fruit appropriately, expand stock raising production energetically, make full use of existing commissariat straw is changed, develop ox, pig, birds to wait energetically, crop of 7 old economy and cultivate birds advocate the economic pattern that produces a division already formed embryo.

东丰县积极推进农村产业结构调整政策，在基本稳定粮食产量的前提下，根据效益和市场的需求，各乡镇适当扩大了瓜菜、油料、甜菜、水果等经济作物的面积，大力发展畜牧业生产，充分利用现有的粮食秸秆转化，大力发展牛、猪、禽等，七大经济作物及畜禽主产区的经济格局已形成雏型。

The first step is to eliminate all kinds of noises generated in the process of collecting traffic video by means of median filter; Then we finish image sharpening with Laplace operator to clarify edges of the video images; finally, image contrast is enhanced with the help of the second-developing packet SDK-2000, which is provided by our video-collecting card. This way, much more satisfactory images are obtained, and preparation is already made for the following work, thats image analyse.Thirdly, according to the characteristics of our system, mobile objects are distinguished by means of image difference. Then some features such as regional area, length and width of traffic objects are selected and extracted. After processing of scale filter, we successfully recognize those moving vehicles appearing in the monitoring regions.Fourthly, some corresponding algorithms are brought forward to automatically identify those familiar traffic peccancies of many sorts, such as red light violation, yellow-line covering, parking in prohibited spots, over-speed running and converse running. Then we find means to snap pictures and to intercept videos of the spot, and collect a lot of relevant information such as the time, the block, the running direction and the weather conditions and so on. According to this information, our traffic management departments could make correct decisions on punishing those drivers who have broken the traffic rules.Considering the complexity of traffic environments on particular blocks, in order to monitor other traffic peccancies effectively, we also have designed the scheme to carry out traffic monitoring by manual.

首先运用中值滤波法对视频图像进行去噪处理，然后采用二阶差分法进行图像锐化，再通过视频捕获卡携带的二次软件开发包SDK-2000进行对比度增强，从而得到比较理想的图像，为后续的图像分析工作做准备；第三，根据系统特点，通过背景图像差分法，分割出监测区中的运动目标，然后对交通目标的区域面积、长度和宽度等进行特征提取，再经过尺度滤波处理，从而自动识别出机动车辆目标：第四，分别设计相应的算法，实现对闯红灯、压黄线、违章停车、违章超速及违章逆行等常见的交通车辆违章行为的自动识别，并自动抓拍违章现场，截取违章视频，采集其它相关违章信息，为交通执法部门进行交通违章处罚提供有力依据：考虑到特殊路段特殊环境下的交通复杂性，为了有效监控其它类型的交通违章行为，本文还设计并实现了对交通违章的手动监控模式。

Under the condition [0mmol/L,raise in vermiculite] of phosphorus stress, variation in root morphology and biomass among different soybean genotypes at seedling stage were studied, the result shows: At two-leaf age, higher P-efficiency genotypes(K1 and K2) don't develop their potential advantages; at four-leaf age, some characteristics of K1 and K2, such as lateral root number, lateral root length, root absorbent area and dry weight of shoot are all less reduced than those of intermediate P-efficiency genotypes(Z1 and Z2) and of lower P-efficiency genotypes(M1 and M2), and dry weight of root and R/S of higher P-efficiency genotypes are more increased than those of the others.

在磷胁迫[0mmol/L，砂培]条件下，对不同基因型大豆苗期在根系形态、生物量等方面的差异进行了研究，结果表明：磷高效基因型在两叶期并未发挥出其基因型潜力的优势；四叶期，磷高效基因型的侧根数、侧根长、根系吸收面积、茎叶干重等性状的受抑制程度均显著低于磷中、低效基因型，而地下干重、根冠比却受到了较中、低效基因型更强的诱导作用。

The requirements for lasers,optical setups,recording ma terials and chemical processing to make large-format holograms of great scenes are discussed.A model of Suzhou Industrial Park measuring 160×180cm,and other large models were recorded using an argon ion laser with an etalon on self-prep ared ultra-fine-grain silver halide plates(average grain size:20nm).Large-for mat transmission holograms (size:50×40cm) of high diffraction efficiency and lo w noise level were obtained with proper exposure and chemical processing.
