查询词典 volume density

Combined GIS with MATLAB, the automatic extraction of RS and geography information of sample plots was realized.5. Introduced the resist-PCA estimation method to build the estimation formula on crown density, stock volume and diameter breast height, good forecast accuracy was achieved and the deficiency of traditional LMS parameter estimation was made up.6. The estimation process software of the model was developed, including data pretreatment, weight function selection, LMS estimation, PCS estimation, resist-PCA estimation, accuracy assessment and other function models, in order to c

摘要4、结合Gls和MATLAB技术实现对样地遥感信息和地理环境信息的自动提取。5、引入抗差主成分估计方法建立郁闭度、蓄积量、胸径的估测方程，取得了良好的估测精度，弥补了传统最小二乘参数估计的不足。6、开发了模型估测处理软件，包括数据预处理、权函数选择，LS估计，主成分估计、抗差主成分估计、精度评价等模块，实现数据处理、模型研建与精度评价的自动化、一体化。

Branch diameter distributions changed from an abundance of small-diameter branches in the upper-crown, and in the middle-crown, composed with differential branch diameter, but only a few large-diameter branches in the lower-crown. Branch volume generally increased from upper- to lower-crown, and reached a maximum around the crown base. Branch density decreased from upper- to lower-crown.

枝条口径分布，从树冠上层多数的小径枝条至树冠中层转变为含不同口径枝条且变异较大，在树冠下层仅由少数大口径枝条组成；枝条体积则由树冠上层向下层增加，至树冠基部达最大值；而枝条密度则从树冠上层向下层逐渐递减。

The effect of motorway traffic divergence and centralizing and decentralizing on railway is described and the effect of cut-down on the traffic volume of the whole railway system on the passenger and freight traffic density of main lines is introduced.

分析了京九线通车对缓解京沪线能力的影响，研究了京沪线旅客列车超员情况，阐述了公路对铁路的分流与集疏作用，介绍了全路规划运量下调对干线客货流密度的影响，最后指出建设京沪高速铁路是京沪线扩能的必然趋势。

The length of railways in operation is an important indicator to show the development of the infrastructure of railway transport. It is also essential data to calculate volume of passenger freight transport, traffic density and utilization efficiency of locomotives and carriages.

铁路营业里程是反映铁路运输业基础设施发展水平的重要指标，也是计算客货周转量、运输密度和机车车辆运用效率指标的基础资料。

The steady model is able to predict the start and the end points of the phase inversion, although the model parameters have no distinct physical meanings. The factors, such as agitation strength, density, viscosity, interfacial surface tension, grafting efficiency and volume fraction etc., have been considered in the dynamic model, which can predict the start point of phase inversion successfully.

稳态模型的参数虽然没有明确的物理意义，但却能给出相转变过程的起点和终点；动态模型则从液液分散理论出发，综合考虑搅拌强度、体系粘度和密度、界面张力、接枝效率及相体积分率等因素的影响，能很好的预测相转变的起点，略加改进后该模型可以用于相转变的全过程模拟。
