On the spiral tube produ ction line, it can be used instead of the circle shears for cutting the edges so as to reduce material consumption and increase productivity by 4%.

在螺旋管生产线也可以代替切边园盘剪，降低材耗，可提高出品率4%左右。

To apply bigger diameter only for the shell at immersion tube inlet area with suitable shell angle, and this makes higher collection efficiency of cyclone by getting lower gas speed at shell wall.

只对在螺旋管，以适合的壳体角度入口断面处的壳体采用更大的直径，它可以通过在壳体壁得到较低的气流速度，使旋风筒有更高的收尘效率。

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。
