We may regard all directive projection information as constitution of two limited angle projection information.

在全方位投影信息情况下，我们可以把全方位投影信息视为两个有限角投影信息的组合。

Its projections on the other two planes are both parallel with an axis of projection, and shows its true length.

在另外两个投影面上的投影均平行相应的投影轴，且反映实长。

Its projections on the other two projection planes are shorter than its true length, and are all vertical to the axis of projection.

在另外两个投影面上的投影长度比实长短，且垂直于相应的投影轴。

According to the pinciple of different axonometric projection at different angles, Visual Lisp can be used to make programs.

依据不同视角得到不同轴测投影的原理，用VisualLisp编程，以视角为变量，连续变化，每个视角下得到的轴测投影图经过消隐后，生成轴测投影动画，所形成的文件大大减小。

From the point on coefficient matrix of the sets of projection equations and in a broad sense axonometric projection ,the research and summarization of the development of projection theory this two centuries has been done.

从投影方程组系数矩阵及广义轴测投影分析入手，对两个多世纪以来的投影理论发展总结评述；通过数学分析，得出计算机绘图优于手工绘制轴测图的理论依据，证明计算机绘图不仅工具方便，且理论上更具有先进性

The program developed with the formula enable the coordinates for points and the parametric formula for curves in the orthographic projection to be transferred into ones in the axonometric projection, which can be directly displayed on the screen. In addition, except for assigned different values to elastic coefficient of the axial direction and the angles of the axes, it is generally adapted in drawing any of the axonometric projections.

用它编程，可以把正投影中点的坐标或曲线的参数方程，转换成屏幕上能够直接显示点的轴测投影的坐标或曲线的轴测投影的参数方程，而且除了赋轴向伸缩系数和轴间角的大小、正负不同的参数值外，对绘任一种轴测投影和相应正投影都具有通用性。

A new local projection algorithm is used to plot the regions of projection in reason. In order to get the excursion of projection correctly, the peak value of the projection is applied to match in current frame.

采用了新的局部投影的方法，在图像中合理地划分了投影区域，在求投影偏移量时提出了峰值匹配的算法，合理地检测到了投影偏移量。

And this paper researches projection ways of coordinate such as the Mercator projection, Lambert projection and linear projection to achieve the conversion of level rectangular coordinate by latitude coordinate and geography.

In which whole length of the expanded equatorial line is assigned as horizontal-axis, and half of length of the expanded prime meridian is assigned as longitudinal-axis.

首先，我们提出了以中央经线和纬线的直接展开为基准的新的全球投影——纬平面投影，该投影以赤道线展开为横轴、以中央经线展开长度的一半为纵轴，纬线在纬平面上投影为一系列平行的直线段。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
