贯顶的

On the basis of analytic geometry, the projection curve types of intersection lines of cone and cylikder, cone and cone on V plane is hyperbola and cone and sphere is parabola.

基于锥与圆柱、圆锥、圆球正贯时，相贯线V 面投影为双曲线和抛物线，且X 向极值点所在高度只与柱、锥轴线、球心距离锥顶高度和立锥锥顶角有关，而与它们的直径无关，给出了求该极值点的作图方法。

A seemingly harmless throw-in from Tostao, level with the edge of the area, was hooked across the area by Rivelinho and that man Pele was there, belying his lack of height to outjump Tarcisio Burgnich and head the ball into Enrico Albertosi's top left-hand corner.

托斯塔奥一次看似没有威胁的界外球掷到禁区线附近以后，里维利诺顺势将球钩到禁区另一端。在那里候个正着的贝利迎球高高跃起与布尔尼奇争顶抢得先机，以弹跳弥补了身高的不足，一记头锥贯入阿尔贝托西把守的大门左上角。

贯顶的，塔状的主轴延伸成不分枝的茎或杆的，如云杉

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。
