气泡浮选槽

PDA laser flow velocity testing technique was used to measure the flow velocity of solid particles in the solid-liquid-gas three-phase system in a flotation cell and obtained the velocity distribution of solid particles so as to provide reliable data for the study on adsorption and deadsoption mechanism of particles onto and off from bubbles.

采用PDA激光流速测试技术，在固-液-气三相体系中对浮选槽中固体颗粒进行了流速测定，获得了固体颗粒的速度分布，为矿粒与气泡粘附过程和脱附过程机理的研究提供可靠数据。

The circular centrifugal flotation cell has many originalities on the pulp aeration, air bubble mineralization, air pulp flow format in the ring shaped tank of the cell, feed method ect, due to the results of fluidics and turbulence and the action of centrifugal and gravitational force ect.

新型高效圆形离心浮选机充分发挥了湍流射流及离心—重力力场的作用，使其在矿浆充气、气泡矿化、浮选槽内矿浆流动形式、给料方式等方面独具特色。在普通喷动床环形区底部引入&充气&可消除环形区底部颗粒&死区&的影响，并能改善环形区气固间的热、质传递。

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。
