PDA(particle dynamics analyzer system) was used to measure the flow velocity of particles in the XFD-12 flotation cell, the results show that tangential mean velocity in the radial direction changes from positive to negative in the flotation cell, naught point emerge in the medium of the radial direction ,it is where backward fluid emerge ,shear stress of backward fluid induce the particle detachment from bubbles .

汁算数据与实际矿石筛析结果都表明，紊流强度增大，泡沫中粗粒级含量减小。 4。用PDA在XFD-12型8L浮选机中测定的速度值，进行混合区、分离区、泡沫区紊流运动功率谱计算，得紊流脉动频率，混合区小于20Hz，分离区在20-30Hz之间，泡沫区在25-35Hz之间，浮选槽内紊流脉动以低频为主，且紊流脉动动能是混合区大于分离区大于泡沫区。

Has attracts the thick liquid and the flotation process dual function, uses the caster type double leaf blade the novel impeller, and increases the design along with the trough body volume to have the honeycomb duct and to install false, the organization is reasonable, the revolution is reliable, the high performance attracts the thick liquid ability in other flotation machine.

具有吸浆和浮选双重作用，采用后倾式双叶片的新颖叶轮，并随槽体容积的增加设计有导流管和假地装置，机构合理，运转可靠，性能优越于其它吸浆能力的浮选机。

具有吸浆和浮选双重作用，采用后倾式双叶片的新颖叶轮，并随槽体容积的增加设计有导流管和假地装置，机构合理，运转可靠，性能优越于其它吸浆能力的浮选机。

The results show that methyl group strengthens the electrostatic attractions, but reduces the H-bonds effect, while benzyl group can make both electrostatic and H-bond effects strong. The theoretical results are identical with the results of the collectors flotation tests. Collecting ability of the quaternary amine salts is better than that of dodecylamine and dodecyl bimethyl amine. The quaternary amine salt containing benzyl group performs best, and it is little affected by pH value. Substitution of N-containing polar group in amine collectors can impact the aluminosulicate minerals flotation.

研究结果表明：甲基的取代可增强阳离子的静电作用能力，同时，削弱它与矿物表面之间的氢键作用；苄基的取代不仅增强药剂的静电效应，而且增加氢键的结合能力；理论分析结果与浮选试验结果一致，季铵盐的浮选能力较伯胺与叔胺的强，连有苄基的季铵盐对铝硅酸盐矿物的捕收能力最强，且受pH值影响小。

Characteristics of trace organics removal was studied during the treatment of algae-laden raw water with two process trains ( dissolved air flotation GAC filtration, dissolved air flotation sand filtration +GAC filtration).

试验以高藻水源水为处理对象，就两工艺流程(溶气气浮+活性炭过滤，溶气气浮+砂滤+活性炭过滤)对高藻原水中微量有机物的去除特性进行了考察。

According to their flotation properties, the cleaning flotation test of the feel mixed by the coarse and fine rough cobalt梑earing sulfide concentrates was successfully carried out and the corresponding new cleaning flotw梥heet was recommended.

同时，论文根据粗粒和细粒硫钴粗精矿的浮选特性，进行了粗细粒硫钴粗精矿混合精选试验研究，提出了相应混合精选的新工艺和生产建议流程。

Methods: Five patients with parkinsonism or dystonia were assigned to general anesthesia using an modified endotracheal tube.

本实验依照人体实验之相关规定进行，五位患有帕金森氏症或肌张力异常的病人接受神经立体定位手术。
