The rotating turbo in the powder concentrator will make the coarse materials return to the mill and reground, while the fineness will mix with the air and go into the cyclone and be discharged the discharge valve which is in the bottom of it. The air which mixed with very little fineness will be purified by impulse duster and discharged by blower and muffler.

选粉机内旋转的涡轮使粗颗粒物料回落重磨，细粉则随气流进入旋风集粉器并由其下部的卸料阀排出即为成品，而带有少量细粉尘的气流则经过脉冲除尘器净化后通过风机和消声器排出。

However, for the collision processes in He target, a large discrepacy between the CTMC results and experimental measurement is found. As is well known, the microcanonical distributions of bounded electrons in CTMC method is quite different from quantal distributions, we modified the initial microcanonical distribution by using eleven different ionization thresholds of electron bounded in target. With modification, we calculated the collisional process of O~(3+) with He, and the total cross sections of all processess are calculated as a function of the incident energies. The agreement with experiments is improved by the modified distributions.

但由于靶电子的微正则分布与量子分布有很大不同，在计算离子与He靶碰撞时发现结果与实验差距很大，我们基于使用多个系统总能量U值，对初始电子的微正则分布进行了优化，使其更接近于量子力学的径向空间分布，然后计算了O~(3+)与氦原子随入射离子能量变化的各种反应过程截面，发现优化极大地提高了计算精度，特别是我们的模型对于描述单电子、双电子丢失过程非常成功。

4The low similarities betweenseed banks and the established vegetation were considered to be the consequences ofthe frequent presence in the established vegetation but not in seed banks of someperennial rhizomatous plants which mainly depended on vegetative propagation toregenerate;insignificant difference in the species composition of seed barks amongtransects, might be accounted for by the fact that the flood drift had functioned as adisseminator for propagules;and with the intensifying of the flooding disturbance,both species diversity and the similarity between seed banks and establishedvegetations declined.

4种子库与地上植被相似性普遍较低，其原因是主要靠营养繁殖以更新种群的多年生根茎植物经常在植被中出现而不在种子库中出现；受水淹干扰的样带之间种子库的种类组成差异不大，说明洪水漂移行使了繁殖体传播和散布的功能；随水淹干扰强度增加，种子库物种多样性指数减小，种子库与地上植被的物种组成相似性下降。

With the increased phosphorus supply, the net photosynthetic rate at saturated light, leaf area ratio, and the concentration of nitrogen and phosphorus increased in both species, and the biomass allocation of A. crenata to propagule also increased. So it was indicated that the increased phosphorus supply could facilitate the growth and reproduction of these two species.

结果表明：随磷营养水平的增加，两种植物在饱和光下的净光合速率和叶面积比升高，各器官的氮浓度和磷浓度均有所增加，其中朱砂根对繁殖器官的投入也增加，表明磷营养水平的增加能够促进其生长和繁殖。

The experiment showed that iron sulfides were easily oxidated in air and of high naturnal oxidation tendency.

By throttles,the high pressure is dropped down to evaporator pressure,and changed with the refrigerant temperature at the gas cooler, the regulation characteristics of the system are different from traditional system.

节流阀把高压侧压力节流到蒸发压力，同时控制高压侧压力并使其随气体冷却器出口温度的变化而变化，CO2制冷系统调节特性与传统制冷系统不同。

The discrete ordinates model was used for modeling the radiative heat transfer, and the effect of slag particles on radiative heat transfer was included.

结果表明：炉体入口存在张角约为10°的中心射流区，其流速和温度均较高，且周围存在明显回流区，回流区内部分颗粒富集；大部分颗粒直接落入渣池，且粒径越大落入渣池时温度越高；炉内温度分布除中心射流区，整体分布均匀，且随壁面灰渣厚度的增加而升高；计算结果与实验测量结果及文献值基本一致。

The mineralogical form in which the iron occurs in the concentrates of zinc sulphide, and the effect of the iron on direct leaching of the concentrates are subjects of this paper.

铁闪锌矿的铁含量可在很大的范围内变化，其物理化学性质也随铁含量而变化，因此对精矿的湿法直接处理产生很大的影响。

Since Al〓Ga〓In〓P possesses larger valence band difference to GaAs and wider energy gap, minor carrier reverse injection from base and space charge region recombination in the emitter are effectively suppressed in Al〓Ga〓 In〓P/GaAs HBT. Under most circumstances, quasi-neutral base recombination current dominates the base current, and its ratio to collector current varies little with collector current and temperature, thus greatly stabilizes the current gain.

Al〓Ga〓〓In〓P/GaAs HBT由于异质结的△Ev较大，发射区禁带较宽，有力地抑制了基区少子反向注入流和发射区空间电荷区复合电流；在大多数情况下，基极电流以准中性基区复合电流为主，其与集电极电流的比值随集电极电流和温度的变化极小，稳定了电流增益。
