  small extraction
This method is unique in that it provides high tracer recoveries and effective removal of interferences with small extraction chromatography columns instead of large ion-exchange resin columns that generate large amounts of acid waste.
      
Under selected optimal conditions, very small extraction (>amp;lt;1%) was observed for trivalent Gd, Dy, Ho, Tm, Yb, Lu; Cs(I) and Cd(II) and separation factors for these elements were better than 103.
      
The extraction of these substances is carried out in a homogenisator with acetone/water (9:1, v/v) and leads to small extraction volumes without further concentration steps during sample preparation.
      
This small extraction electrode size then confines the field in a smaller space and higher field strength can be generated by a lower applied voltage.
      
In the past, the cumulative effect of numerous small extraction sites has been the gradual removal or degradation of areas of Box-Ironbark vegetation.
      


The crane passing dust collecting cover is a new type dust collecting cover. Relative to the canopy and semiclosed cover, it not only covers the shortage of dust escaping of semiclosed cover when loading material, but also avoids the shortage of being disturbed by crosswind in canopy and small extraction is needed for treatment It can collect the dust during whole arc furnace operation circle with efficiency, and no influence on production

天车通过式捕集罩是一种新型的电炉烟气捕集罩。与目前常用的屋顶罩和半密闭罩相比,既克服了半密闭罩不能捕集加料时的烟气的缺点,又避免了屋顶罩易受横风干扰,处理风量大的弊端。它可以捕集电炉冶炼全过程的烟气,具有捕集率高,不影响生产冶炼工艺,投资省等优点。适用于各大、中型电炉的烟气捕集

Gibbous extraction electrode for MEVVA ion source is introduced. It is indicated that gibbous extraction electrode can be used to force the ion beam spreading widely like a convex. So intenser ion beam and larger uniform beam spot can be obtained in smaller extraction area and shorter extraction distance. Gibbous extraction electrode which can meet the demand of applications was got by experimentally comparing several different structures of electrode.

介绍了金属蒸气真空弧(Metal vapor vacuum arc,MEVVA)离子源的凸形引出电极的研制。研究表明, 凸形引出电极可以完成离子束的强制发散功能,从而在较短的引出距离和较小的引出电极面积的条件下得到大的束斑和均匀可应用的束流分布。通过对几种不同的电极结构的比较研究,得到了满足应用要求的凸形引出电极。

In this paper, the significance and the request of polyester film of small extraction and B-class insulation are introduction, the situation of study in China is recalled, and its development is discoursed.
