It is a fine powdery material feeder suitable for non-cohesive materials like coal powder, cement, chamotte, limestone, shale, gangue and clunch.

作为细粒物料给料设备，适用于运送粉状、料状或小块状态的各种非粘性物料，如煤粉、水泥、熟料、石灰石、页岩、煤矸石、粘土等粉状、粒状或小块状物料。

Tested results and analysis show: seed condition has a significant effect on bulk density, a comparatively significant effect on drag coefficient, and little effect on particle density and restitution coefficient of rice seed; moisture content significantly affects bulk density, particle density and drag coefficient of coated rice seed; variety of seed has little effect on the properties of coated rice seed.

试验结果和分析表明：稻种状态对容积密度影响显著，对漂浮系数影响比较显著，对籽粒密度和恢复系数影响较小；含水率对包衣稻种的容积密度、业粒密度和漂浮系数影响显著；品种对包衣稻种的物理特性影响较小。

We describe the specific silencing of reporter gene lacZ in FHM cells (muscle cells of fathead minnow, a fish cell line) by either expressing small hairpin RNAs from plasmids or transfecting small interfering RNAs transcribed in itro.

在FHM细胞内通过转染质粒表达小发夹RNA或者直接转染小干扰RNA能特异沉默报告基因LacZ的表达，且siRNAs 抑制效果更加明显；这两种类型的小双链RNA在Hela细胞内同样能抑制报告基因的表达。

Even more remarkable, children who had two or more dogs or cats had an even greater reduction, up to 77 percent, in risk of allergies. And not only were they less likely to develop allergies to cats and dogs, but also to dust mites, short ragweed and blue grass.

更值得注意的是，那些拥有两只或更多小宠物的儿童，患过敏症的病例甚至要少很多，比同龄儿童降低了77％，他们不但不易对小猫和小狗过敏，而且对尘粒、豚草和早熟禾等过敏原的过敏率也下降了。

The results show that: the tensile strength, flexural strength and flexural modulus increase by about 10.4%, 62.1% and 122.3% respectively when the mass fraction of the aluminum powder increases from 0 to 50%, while elongation at break and impact strength decrease by about 65.0 and 74.4% respectively; the tensile strength, elongation at break and impact strength all increase with decreasing the particle sizes of the aluminum powders.b Nylon-12 coated metal powders for the indirect SLS process were prepared by the dissolution precipitation process. The coated powders have only 1.0 wt% nylon-12, and their SLS green parts have sufficient strength for features as small as 1.0 mm to be built and post-processed and high dimensional accuracy. The green parts were subjected to the post processing processes including binder decomposition and infiltration of epoxy resin, and then the metal/polymer composite parts with relatively high strength and accuracy were formed.At present, micron-scale inorganic fillers have been widely used to reinforce nylon SLS parts.

将该法制备的尼龙12覆膜金属粉末用于以下两个方面：a使用铝粉增强尼龙12的SLS成形件，通过溶剂沉淀法制备尼龙12覆膜铝复合粉末，研究了铝粉含量及粒径对SLS成形件性能的影响，结果表明：铝粉分散均匀，并与基体有良好的界面粘接；当铝粉含量从0增加到50wt％时，成形件的拉伸强度、弯曲强度、弯曲模量分别提高10.4％、62.1％和122.3％，冲击强度和断裂伸长率下降65.0％和74.4％，耐热性及尺寸精度也得到提高；断裂伸长率、冲击强度及拉伸强度均随着铝粉粒径的减小而增大。b使用溶剂沉淀法制备了间接法SLS用尼龙12覆膜金属粉末，该覆膜粉末中聚合物粘接剂的含量仅为1.0 wt％，其SLS初始形坯具有较高的精度以及足够满足后处理要求的强度，最小精细结构的尺寸达1.0 mm。

After re-reduction, the dispersion of Pt particles is improved.

而再氧化却可使已聚集的Pt粒外层被氧化并剥落下来迁移入沸石小笼，从而使较大的Pt粒达到再分散。

For a higher packing fraction, a greater absorption strain was induced in the vessel packed with a larger initial powder size, while a greater desorption strain was present in the vessel packed with a smaller initial powder size.

在较高粉末填充率的情况下，较大的吸氢应变会出现在装填较大初始粒径粉末的储氢罐壁上，而较大的放氢应变则会出现在装填较小初始粒径粉末的储氢罐壁上。

The results showed that the mixed surfactant had well distributed and uniform particles, and a size of 40-80μm. When the mass ratio of prepolymer and RDP was 1:1, the micro-capsule size was minimum, with little melamine resin deposited on the surface.

结果发现，复合型活性剂对微胶囊具有很好的分散作用，制备出的微胶囊颗粒均匀，粒径经检测在40~80μm；预聚体与RDP的质量比为1：1时，微胶囊的粒径最小，且只有少量蜜胺树脂沉积在微胶囊表面上。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
