查询词典 height block

On the basis of Earth surface space using reference ellipsoid as height basis, map space using Gauss-Kruger projection plane as height basis, a viewpoint is proposed that map projection actually establishes corresponding relationship between the height bases of two different spaces above. From the viewpoint of projection and visible representation, the relationships among earth surface space, RS imagery space and map space are analyzed; the differences among different representations of earth surface space are identified theoretically; virtual reality is applied to the representation of land surface space, and a prototype of real 3D virtual reality system based on spatial information is developed. By means of digital simulation, virtual reality representation of land surface space in visual image space is realized.

在以参考椭球面为高程基准面表征地表空间、以高斯-克吕格地图平面为高程基准面表征地图空间的思想基础上，提出了地图投影实质上是建立两个空间的高程基准面之间关系的观点；从投影和可视表达的角度，分析了地表空间、遥感图像空间、地图空间之间的关系，从理论上区分了对地表空间的不同表达方式之间存在的差别；将虚拟现实技术应用于地表空间的表达，研制了空间信息三维虚拟现实系统原型，利用数字模拟技术在视像空间实现了对地表空间的真三维虚拟现实表达。

Bamboo variation ofmicrodensity of all age-degree and all height bamboo from bamboo green tobamboo yellow as follows:The downtrend ladder of microdensity the firststage from bamboo green to bamboo yellow is relatively large,normally at theplace 0.35 from bamboo hull(the thickness of from bamboo hull to bambooyellow is 1)micro-density downtrend ladder begin to get smaller,variancerange of microdensity is smaller.When reaching near bamboo yellow area,microdensity reaches its minimum value,and when reaching bamboo yellowsection density increase rapidly,the minimum density of bamboo is only 50% orless of maximum density.Bamboo yellow is comprised of stone cells whichhave thick cell wall,so its density is high,normally 50% to 100% more thanminimum density.Bamboo yellow′s lay thickness is thin,normally the samethickness for all age-degree and all height bamboo,about 0.8mm.From 1 age-degree bamboo to 2 age-degree bamboo during growth,the increase of averagedensity is mainly in bamboo pulp section,from 3 age-degree bamboo to 4 age-degree bamboo,the decrease of average density is mainly decrease in the pulpsection.Same age,same height,the less the density ladder of bamboo radialthickness,the higher the mechanical strength.

所有年龄所有高度的竹材微密度从竹青到竹黄对材性变异规律如下：从竹青到竹黄开始下降梯度较大，一般到相对竹皮距离0.35左右处(整个竹壁厚度为1)，竹材微密度下降梯度减小，微密度的变化范围变小，到近竹黄处，微密度达最小值，而后到竹黄部位密度大幅上升，竹材最小密度一般只有最大密度的50％或更低，竹黄由厚壁的石细胞组成，所以密度较大，一般比最小密度增大约50％-100％，厚度较薄，不同年龄不同高度竹材的竹黄厚度相差无几，约在0.8mm左右；竹材从1度竹到2度竹生长过程中，平均密度的增长主要发生在竹肉部分，从3度竹到4度竹生长过程中，平均密度的下降主要发生在竹肉部分，同一年龄同一高度，竹壁厚径向的密度梯度越小，力学强度越高，随着年龄的增大，密度梯度越来越小(1度竹除外)，随着高度增加，密度梯度越来越大。

When the falling height was less than 3 m, the injuries mainly occurred on the limbs and craniocerebrum, and as the falling height increased the occurrence rate of the fracture of the spinal column and pelvis also increased. When the falling height was above 8 m, the injuries of the intrapleural and intraperitoneal organs significantly increased.

Methods The subjects were 2 550 children aged 17~20 years from five cities of China.The adult height of children was measured and the midparental height was determined by the height self-reported of childrens parent.

For nearly fifty years, concept of normal height has been adopted in China. However, thanks to the rapid development in geodesy and other computation technology, the HASL can be computed as accurately as the normal height. Particularly, the HASL is very fit to the case of wide and high multimountain areas of China. This ideal of orthometric height would be accepted by many people.

尽管近50年来我国仍采用正常高系统，但随着时代的发展、研究的深入，如今推求正高的精度又与正常高的非常接近，况且它又符合我国幅员广大的高海拔山区的实际情况，因此用正高代替正常高的观念将会被人们所接受。
