The main functions are inquiry、countingarea and plotting cartogram. The classification result is input in this system firstly andvector is created. The vector is operated, such as counting its area, then area and cartogramis obtained. Moreover, we can analyze area and cartogram by means of quantitativeanalysis.

该子系统首先将分类后的图像导入本子系统，进行矢量化，然后对矢量后的图形进行面积统计等操作，得到统计面积及统计图，并采用定量分析的方法对得出的面积值及统计图进行分析。

The results showed that plant height increasing speed was significantly slow at the former and middle stage when K level was above 180 kg/hm2.On the contrary,the height of case-hardened plant improved markedly.When the K level was above 135 kg/hm2,the stem girth and maximal leaf area differed significantly as compared with CK,so did LAI.Yield and product value per unit area took the first place when 180 kg/hm2 potassium was used.Average price and proportion of middle and first grade tobacco leaf of 225 kg/hm2 potassium treatment were the highest as compared with other treatments and CK.Four economic characters of the two treatments differed at obvious significant level as companied with CK.The total sugar and K2O were increased,nicotine, total N,protein and Cl- were decreased with increased K levels.The potassium lacked symptom was alleviated with increased K levels,no symptoms was observed when 180 kg/hm2 potassium was used,the degree of weather infected fleck was decreased when the K levels was increased.

结果表明，在烟株生长前中期，当施钾量达到180 kg/hm2以上时，株高增长显著变慢，而定型株高则显著增高；茎围和最大叶的面积在施用135 kg/hm2以上的处理与CK之间的差异性达到极显著水平，叶面积指数也存在显著差异；单位面积产量和产值以施用180 kg/hm2的处理居首位，中上等烟比例和均价以施用225kg/hm2的处理最高，这两种处理的以上4个经济性状与CK之间存在极显著性差异；烟叶中的总糖和K2O含量随施钾量的增加而上升，烟碱、总氮、蛋白质和C-含量则下降；缺钾症状随施钾量增加而减轻，至施用180kg/hm2时已无缺钾症状；烟叶气候斑的发生程度也随施钾水平的提高而减轻。

The paper puts forward the mechanism of combined waveform and computation of a SPWM area center equivalent.Harmonic of double pole SPWM waveform is analyzed in this paper.

文中给出了按照面积中心等效法合成SPWM波形的机理以及面积中心等效算法，并对双极性面积中心等效法生成的SPWM波形进行了谐波分析。

Three LEDs biology light sources with different intensity for cell or tissue culture have been developed in the third part of this thesis. A concave lens to expand the beams of light, to focus the rays of light and an array of LEDs being set in the sphere connected with Fresnel lenses are three newly-designed in our systems.

实际测试数据表明：低强度光源输出的辐射照度范围为0.0021—0.9961(W／m~2)，在直径20mm的照射面积内所测辐射照度的标准偏差为0.02W／m~2(n=40，Mean：0.71 W／m~2)；中等强度光源输出的辐射照度范围为0.3579—11.2286(W／m~2)，在直径30mm照射面积内所测辐射照度的标准偏差为0.02W／m~2n=60，Mean：6.37 W／m~2；较高强度光源输出的辐射照度范围为17—110(W／m~2，在直径40mm照射面积内所测辐射照度的标准偏差为0.02W／m~2(n=80，Mean：71.54 W／m~2)。

Beijing Statistical Bureau, the National Bureau of Statistics announced in Beijing survey data Corps area is the use of per capita housing, Ministry of Construction announced that the per capita housing area, and statistics department's forecast of 25.9 square metres per capita housing area is 6.96 square metres of construction gaps; Second, the use of different population data, the use of population statistics department for the resident population of the district towns built for the 1115 million people, and the Ministry of Construction of the population is the use of non-agricultural household registration population to 880.2 million.

北京市统计局、国家统计局北京调查总队公布的数据是人均住房使用面积，建设部公布的是人均住房建筑面积，与统计部门测算的人均住房建筑面积25.9平方米仍有6.96平方米的差距；二是使用的人口数据不同，统计部门使用的人口为城镇建成区的常住人口，为1115万人，而建设部使用的人口是全市非农业户籍人口数，为880.2万人。

The air conditioner forced draft fan ventilates the way to have longitudinal and the crosswise two kinds generally, the lateral ventilation the air current overflow sectional area is big, the wind speed is small, easy to create the big area the dead angle, but longitudinal ventilates the air current the overflow sectional area to be small, the wind speed is big, the dead angle area is very small.

冷风机通风方式一般有纵向和横向二种，横向通风的气流过流断面积大、风速小，容易造成较大面积的死角，而纵向通风气流的过流断面积小，风速大，死角面积很小。在使用条件许可的情况下，应该尽可能采用先进的纵向通风方式。

For the five-storey factory building, each floor area of 1423 square meters, each plant construction area of 7116.8 square meters, total construction area of 4 square meters 28467.2; plant the first floor 5.5 meters high, two to five-storey are 4 meters, height 22.5 meters; Distribution Freight has dead weight 2000kg, lift height of 2.5 meters.

厂房为五层，每层面积1423平米，每栋厂房建筑面积7116.8平米，四栋建筑面积共28467.2平米；厂房首层高5.5米，二至五层高均为4米，楼高22.5米；配有载重量为2000KG货梯，电梯高度2.5米。

As a result of half registers requirement, the 24.6% area reduction for high order (126th-order) FIR filter is obtained, which result in 15.8% area reduction for the 4-stages decimator (20.9% area reduction for 3-stages decimator).

由於只需使用一半的储存元件，本架构相对於直接结构摺叠架构而言，可使降频器里的高阶有限脉冲响应滤波器减少24.6%的矽面积，进而达到整体使用四个阶段降频器15.8%的面积节省(对於三个阶段降频器，整体面积则可减少20.9%)。
