The spatial variability of an experimental field infiltration rate is examined by using the theory of time series of dynamic analysis method. The experimental field is 45m×50m, and had been irrigated by two sprinkler lines with different water quality in the last five years.

一、引言 80年代以前土壤科学和水科学工作者都用经典的统计方法研究土壤特性和多孔介质中水、热、气、溶质等运动特性在空间上的变异性。

They seemed to confirm his theory that these types of spiral movements may be a particularly efficient way to generate force in a small sphere of space.

他们似乎证实他的理论，这些类型的螺旋运动，可能是一个特别有效的方式来产生的力量在一个小范围的空间。

Thermoluminescence and Thermally Stimulated Current have been applied extensively in the research of the structure of traps, the storage and transportation of the charge controlled by traps and the molecule motion of polymers.

热发光和热激电流作为研究聚合物分子中陷阱结构，以及它所控制的空间电荷的存贮和输运特性：聚合物的结构转变和分子运动的重要工具，已经获得了广泛应用。

Toga is living in a beautiful area with lots of space for her to run around and exercise.

Toga目前住在一个很漂亮的地区，有很多空间可以跑来跑去、运动。

Therefore, the geographical and topographical factors influence upright motion of atmosphere, which results in difference of precipitation distribution.

地理地形因子影响大气的水汽输送和大气的垂直运动，从而导致其对空间降水分配的差异。

After the simulation system based on these algorithm for motion planning is set up, the correctness of partition principles is confirmed by many typical simulation experiments, so does the feasibility of motion planning for multi-joint robot based on topological dimension reduction method.

经过状态空间的划分，得到许多连通块，根据连通块之间的连通性的判别条件，构建特征网，最后根据搜索算法在特征网上搜索连通路径，进而从特征网上的连通路径求出机器人运动的几何路径。

Traditional KF is utilized to identify structural parameters by transformation from dynamic system differential equation to state space, and combining structural parameters and responses in system state vectors in this dissertation.

利用传统KF将动力学系统的运动微分方程转换到状态空间中，然后将待识别的参数同结构的响应—并作为系统的状态向量进行识别。

In this paper a Nonlinear Variable Dimension Estimator is proposed for tracking maneuvering spacecraft. Two process models were incorporated by the Unscented Kalman Filter to account for the dynamic uncertainties of the target of interest: a nonmaneuvering model based on the two body problem and a maneuvering model taking the forced acceleration as the unknown system input to be estimated.

当飞行器处于无机动的巡航状态时，无色卡尔曼滤波器使用常规的二体问题模型描述其运动规律，而当飞行器被认为开始机动后，滤波器将扩展系统的状态空间，将机动加速度作为状态变量进行估计，从而增加了模型的适应性。

Ideal housing for large object detection, varying object size, confined spaces, two-up feed tracks and two axis movements.

理想的外壳适合用于大型物件检测、不同的物体大小、狭窄空间、双上进料轨道和两轴运动。

Transient in change, and almost undistinguishable in the mingling of light, space, and motion, they have a logic structure that, with their complex composition, does not belong to the quotidian world of reality.

以光、空间和运动组成不能够确切地辩认的，变幻交错即现即逝，迷宫似的脉络雾霭构成不属于任何现实世界的逻辑结构。
