垂直 perpendicular; vertical; squareness; verticality; perpendicularity 两线垂直相交。the two lines meet at right angles. 设 ab 垂直于 cd。let ab be perpendicular to cd. 当表面与射线垂直时,射线的强度最大。when a surface is perpendicular to the rays, their intensity is at its maximum
In the open ocean above the deep sea bed, the vertical structure of the water mass is characterized by the presence of one of more thermoclines . 处于深海床之上的外洋中,水体的垂直结构的特点是存在一个或一个以上的温跃层。
The two basic types of organization groups for instruction are vertical and horizontal 教学组织的两种基本形式是垂直结构和水平结构。
The vertical structure of each forest community were obvious and could be divided into tree layer , shrub layer , herbage layer and lianas 各群落垂直结构十分明显,可分为乔木层、灌木层、草本层和层间植物。
The species diversity index of the tree layer was a bit low , and the general trend was shrub layer > treelayer > herb layer 乔木层物种多样性指数偏低,垂直结构各层次间物种多样性大小依次为灌木层>乔木层>草本层。
Fig . 2 vertical structure of the grid points in the orsm : upper levels are close to the pressure coordinate while lower levels are terrain - following 图2 orsm网格点的垂直结构:上层趋向气压坐标,而下层坐标则随地形变化。
The complicated vertical structure could be divided into tree layer , shrub layer and herb layer , as well as a definite number of interstratum plants 群落垂直结构复杂,可分为乔木层、灌木层和草本层,并有一定数量的层间植物。
The thesis has also done a systematical analysis on the sources and the seasonal variations of the warm currents in the ecs 论文还对东海各暖流的水源及其季节变化也进行了系统的分析。黄海环流的季节变化显著依赖温度分布及垂直结构。
The two components have identical vertical structure and physical process . the global spectral model component uses spherical harmonics as horizontal basis functions 这两部分采用相同的垂直结构和物理过程,都用球谐函数作为水平基本函数。
However , traditional mosfet models in hspice library are built for lateral mosfet with small power and they can ’ t represent the characteristics of power vdmos well 然而, hspice模型库中传统的mosfet模型都是根据横向结构的小功率mosfet工作机理建立的,无法准确模拟垂直结构的功率vdmos的各种特性。
To preserve the vertical structure , it is important that the environmental flow surrounding a tropical cyclone is homogeneous enough so that the shearing forces will not be able to disrupt the axial alignment 若要维持垂直结构不变,热带气旋四周环境的气流亦要保持匀称,免使轴心受到过大的切变力所扰乱。
