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。

Separation from the flock was more likely when original flock size was larger but less likely if more extra-range foragers were present. The duration of separation events was longer when there were more extra-range foragers.

分离事件更可能发生于大的群体，但其发生率与参与者的数量呈负相关；而参与分离的个体愈多，分离持续的时间就愈长。

There is still no effective method on effectively curing this disease. In this paper, egg-yolk antibody against WSSV was prepared and its effectiveness on preventing and curing this disease was tested. In order to get adequate WSSV antigen, the differential-speed centrifugation and the sucrose gradient ultracentrifugation were used to isolate and purify WSSV from the foregut and gill tissues of shrimps affected with WSSV.

为了获得足量的WSSV抗原，本文以感染WSSV的对虾前肠和鳃等组织为材料，分别利用差速离心法和蔗糖密度梯度离心法进行了WSSV的分离纯化，结果表明：利用差速离心法虽然能够使所分离的WSSV的完好率达70﹪左右，但其中杂质较多，病毒粒子的收获量较少；利用蔗糖密度梯度离心法提取WSSV，虽然其完好率稍低于差速离心法，但也可以达到60%以上，并且，所得到的WSSV的量要大大高于差速离心法，适合于WSSV的大量分离。

The composition of fatty acids in oil and fat was detected by gas chromatography and fire ionization detector at home,however,the reports about the separation and detection of triglyceride in oil and fat were very little.

对油脂的分析，国内主要是采用气相色谱分离和火焰离子化检测器检测其中的脂肪酸组成，而对甘油酯的分离和检测报道较少，国外研究者利用色谱和质谱联用技术对甘油三酯的分离和检测做了大量的研究。

The existing gas-producing and drainage technology can take water out of well hole efficiently. However, it demands considerable ground equipments and lots of money to run so that this will seriously affect the profit in gas reservoir exploitation.

现有排水采气技术虽然能够有效地将井筒中的地层水采至地面，但也给地面的气液分离带来了困难，不仅需要建设大量的地面气液分离设备，而且对所分离出的地层水的处理也需要投入大量的资金，影响着气田的高效开发。

This paper presents a rapid inversion method for 3D apparent density based on separation and continuation of potential field. The new method is carried out in the following three steps. Firstly, the gravity field on the plane is separated by a cutting method into several parts corresponding to strata of different depth. Secondly, by the way of downward continuation, the field resulted from different strata is respectively reduced to a plane corresponding to its depth.

文中提出了一种基于位场分离与延拓的视密度快速反演方法：首先应用场分离的切割法对平面上的重力场进行不同深度层源的切割分离；然后运用大深度向下延拓方法将各层的场延拓至相应的深度；最后反演出各深度层的密度。

The separation behavior of o hydroxybenzoic acid, m hydroxybenzoic acid and p hydroxybenzoic acid in high performance capillary zone electrophoresis was investigated using cetyltrimethylammonium bromide as reversed reagent for electroosmotic flow The effects of pH of buffer solution and volume fraction of methanol on the separation, peak shape and elution order were studie

采用十六烷基三甲基溴化铵为电渗流改性剂，考察了邻羟基苯甲酸、间羟基苯甲酸和对羟基苯甲酸在高效毛细管区带电泳模式下的分离行为，研究了缓冲液的pH和添加剂甲醇的用量对这 3种同分异构体的分离、峰形和出峰顺序的影响，并据此优化了这 3种异构体的分离条件。

Gallo laboratory strain of AIDS was reported米库拉斯波Bo Weike separated, the source of its Boboweike has been vague, then simply said to be from a number of patients with mixed blood, This separation is very normal. In May 1986, Gallo laboratory in the "Science" made a correction of their May 4, 1984 posted on the "Science" on the paper, the French had mistakenly provided by the LAV strain of the photos as HTLV-3 The strain of photos.

盖洛实验室的艾滋病毒株据称是米库拉斯·波波维克分离出来的，对其来源波波维克一直含糊其词，后来干脆说是从许多患者的混合血液中分离的，这种分离方法是很不正常的。1986年5月，盖洛实验室在《科学》发了个更正，他们1984年5月4日登在《科学》上的论文中，误把法国人提供的LAV株的照片当成了HTLV-3株的照片。

On the basis of the fundamental theory as illustrated in binary Pb-Ag system,a segregating method by crystallization has been adopted to separate lead from lead-silver bullion of 20-25wt% Ag,and thus a production alloy more than 90 wt % Ag was obtained.

根据 Pb—Ag 二元相图的基本理论，采用凝析结晶分离的方法，分离铅银合金，使合金中的含 Ag 量由20～25%富集到95%以上，并探索了分离过程中的一些基本规律和现象。

The comparison is made about the RELAX and ML, the RELAX-AS and the ML-AP, The weightiest characteristic of the current estimation of the signal parameter in getting the new estimation in the RELAX-AS was found.

这种最大依赖性使得松弛算法的交替分离解法收敛速度非常慢-这是松弛算法的交替分离解法的严重缺陷，这种最大依赖性使得松弛算法的交替分离解法在有系统误差时能够有效地抑制局部极值，这是它的一个重要性能。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.
