动量矩伸展体的每个组成微粒的角动量的矢量值。

Child growth and development in the eye, the eye grew from a small, axial length gradually increase, if the eyeball as a sphere, it has three axes, namely, longitudinal, transverse, sagittal axis, a sphere is the length of the three-axis equivalent.

儿童的眼睛在生长发育中，眼球由小长大，眼轴逐渐增长，如果将眼球看成一个球体，它有三个轴，即纵轴、横轴、矢状轴，一个正球体的三个轴的长度相等。

Methods A prospective study of 48 patients with thoracolumbar junction burst fracture (T12-L2), 15 with and 33 without neurologic deficit were included. Computed tomographic scans were used to measure the sagittal and transverse diameters and the surface area of the spinal canal at the level of injury, as well as one level above and another level below the fracture level. Injury severity scores were calculated for both groups.

Chapter 2 discusses the aperture couple theory which is very useful to resonant systems. The uniqueness theorem of electromagnetic fields in lossless regions and the formulation of equivalant principles are presented.

第二章利用等效原理和并矢格林函数研究了谐振系统常用的耦合方式孔耦合的一般理论和小孔耦合的偶极子模型。

In order to solve exactly the dynamic problems of the double coordinate coupling harmonic oscillators, the quantum unitary operator corresponding with classical canonical transformation is derived using the momentum eigenvector in Fock representation by constructing asymmetric integration.

为了精确求解双模坐标耦合谐振子体系的动力学问题，利用动量本征矢在Fock表象中的表示构造不对称积分，找到了与经典正则变换对应的量子么正算符。

This method mainly studies the change detection based on the judge of temple and threshold value of the land use class. The land use patch is expressed by vector polygon along with raster region. First the spectrum feature databank with histogram, texture and shape features of the patch is formed. Then, the patches are classified and their change types were judged.

其基本思路是在矢栅位置配准的基础上，以矢量多边形和栅格面阵共同表示的土地利用图斑为基本单位，建立土地类别解译标识，在此基础上对所有图斑进行基于图斑的分类、利用检测模板和阈值来判断图斑类型是否发生变化，并对变化图斑进行表示和更新。

Based on the improvement of Taubin s discrete curvature estimation method of triangular mesh by the adoption of area and angle weighted triangle vertex normal vector calculation formula and triangle centroid weights, a novel algorithm for triangular mesh regularization is presented.
