Ln the memory of dynamic data system there are 500,000 measured data. This paper deals mainly with the change of cutting area in self-excitation qualitatively and quantitatively. The changes of position of cutting edge and cutting area are indicated with graphic method. The m...

文中重点叙述了利用上述DDS对自激振动时的切削面积变化规律进行定性与定量分析研究：利用计算机对切削刃位置和切削面积变化用图示法使之"可视化"：通过统计法建立起来的切削面积数学模型，可对动态切削面积进行实时解析计算，最后通过均方差分析，对4种算法进行比较，提供了实用而准确的计算方法与结果。

To provide credible data for empirical model,a method of calculating the weighted average gray value of compartment area was designed in this paper.It worked especially when the compartment area was as large as pixel.The GeoTIFF form was adopted as the RS data type.The Matlab software was used to read and store RS image.The pixel was divided into smaller units to calculate the area of spackle in each pixel by counting the amount of the units.

：为了给遥感反演模型提供可靠数据，该文设计了一种按面积加权计算不规则图斑遥感影像灰度值的方法，特别是当图斑面积接近像元大小的时候；遥感数据采用被广泛支持的GeoTIFF格式，使用Matlab将遥感影像的灰度信息及元数据读取并存入数据库中；通过将像元分解成更小的单元，统计各像元在图斑内小单元的个数，计算图斑在各像元所占的面积，按照面积加权的方式计算得到图斑的平均灰度值。

Although genotypes with 1 or 2 wx gene nullshould have a significant higher peak viscosity, no significant difference was foundbetween them and normal wheat. Some varieties with Wx-B1 protein deficiency had anormal peak viscosity for their volume weights were low.

研究还表明，峰值粘度与剑叶面积与倒2叶面积比值极显著负相关，剑叶面积与倒2叶面积比值过大的品种也难以有较高的峰值粘度。

The height of bulliform cell groups reached 0.18 of leaves thickness, which was another important quantitative characteristic to achieve function of bulliform cells.

泡状细胞的周长面积比仅占普通表皮细胞的0.723，是泡状细胞功能实现的重要数量特征；(2)以细胞面积、周长、等效圆直径、每平方公厘细胞数、周长面积比，可以建立小麦叶片泡状细胞Fisher's线形判别函数，判别正确率达99%；(3)泡状细胞组高占叶厚的比例达到了0.18，是泡状细胞功能实现的又一重要数量特征；(4)相关分析表明，泡状细胞组长、泡状细胞组高、泡状细胞组面积均与泡状细胞距离叶缘的位置呈极显著负相关。

Supervised and unsupervised image classification were applied to the study area TM image and t o the paddy field TM image. And the early rice areas were calculated by each met hod. Using the proposed methodology improved the quantitative accuracy of ear ly rice area estimated up to 93.98%, whereas it was 82.83%when image classific ation was used only. The extracted information from the c lassification is belonging to the early rice and not to any other vegetation. Si nce the GIS database is available, the method is easily applicable to any new RS images.

不同方法比较结果表明：非监督分类法不能用于提取丘陵山区的水稻种植面积；只用TM资料估算龙游县早稻面积，与统计数据相比，平行六面体分类法、最大似然分类法精度分别达到82.83%和59.95%；而用GIS 与TM资料集成技术对水田分布图进行分类估算早稻面积，平行六面体分类法、最大似然分类法的估算精度分别达到93.98%和60.65%，所以利用平行六面体分类法对南方丘陵山地早稻种植面积估算是可行的。

Based on the acquisition –processing-abstraction of data, the structures an quantities of land use/cover change, the change of degree, the land use/cover dynamic degree and the index of the land use/cover dynamic degree were researched and analyzed comprehensibly in two different periodes(1990-1999,1999-2002) and sum up the conclusion.

结构变化不明显。水域、居民地、耕地动态度比较大，变化较为剧烈；未利用地动态度最小，变化缓慢。1990-2002年间水域、居民地、耕地与其他土地利用/覆盖类型间相互转化面积差额较大，转入面积大于转出面积，即在相互频繁转换同时单边转入明显；林地、草地、未利用地与其他土地利用/覆盖类型间相互转化面积差额不大，处于一种动态均衡状态。

Workstation Management ("rooms within rooms"). Incorporates more flexible room categories that allow users to calculate physical areas, such as areas for housecleaning or energy management, separate from occupiable areas for department assignment and chargeback.

工作台管理合并更多灵活的房间类型，允许用户计算物理面积，比如可清扫的面积或进行能源管理的面积，还可以在部门分配和内部计费的时候，把占用了的面积区分出来。

During the early growth stage of seedlings, basal stem diameter and paripinnate number were decreased with the increasing of shade, taproot length, root : shoot ratio, total dry weight and leaf area per seedling were maximal under 37.3% NS, specific leaf area was increased with the increasing of shade, but the relative growth rate was declined. Seedlings grew fastest under 0.6% NS, suggesting that nutrients stored in seeds played an important role at the early growth stage. The treatment of 37.3% NS was best for established seedlings in seedling height, basal stem diameter, paripinnate number, rachis length, the maximum sub-leaflet number of individual paripinnate, leaf area per seedling, relative growth rate and net assimilation rate. Light intensity was positively correlated to total dry weight, and negatively to specific leaf area. The maximum of SLA was observed under 15.5% NS.

生长早期的幼苗基径和复叶数随遮荫程度的增加而降低；主根长、根冠比、总干重和单株叶面积均以37.3% NS处理最大；比叶面积随遮荫程度的增加而增大，而相对生长率则降低；幼苗株高在0.6% NS下增长最快，表明种子中贮藏的营养物质对幼苗的早期生长可能具有重要作用。37.3% NS处理对定居后绒毛番龙眼幼苗的生长最有利，幼苗的株高、基径、复叶数、叶轴长、复叶最多小叶数、单株叶面积、相对生长率和净同化率均在37.3% NS处理下获得最大增长；幼苗总干重随光照强度的减弱而降低；比叶面积在15.5% NS处理时最大。
