细小

When the Al-Mg-Zr-Sc welding wire was used as filling material,the grains of welding seam were refined obviously,and the weld joint was greatly strengthened by forming of fine equiaxial grains layer in fusion zone .

但采用Al-Mg-Zr-Sc合金焊丝为填充材料时，焊缝晶粒组织明显细化，熔合区形成的细小等轴晶层提高了基材与焊缝填充材料的结合力，焊接接头的屈服强度比采用Al-Mg-Zr合金焊丝为填充材料时提高了100 MPa，显著提高了Al-Mg-Sc合金焊接构件的许用强度，因此焊接Al-Mg-Sc板材更宜采用Al-Mg-Sc-Zr焊丝。

It is worth mentioning that the Fe-Ti-C system of 75wt% Fe content belongs to low exothermal system, the combustion synthesis reaction took place at 734'C under the preset heating rate 1000℃/s based on the electric field, and there were small TiC particles without Fe〓Ti in the products, which also was one of the novelties of this research.

值得一提的是，对于Fe含量高达75wt％的Fe-Ti-C体系实际上属于低放热体系，然而在电场诱导下，当预设升温速度提高至1000℃/s，在743℃时发生了燃烧合成反应，所获的合成产物中TiC颗粒细小，且没有Fe〓Ti相出现。

Two reasons can be explained the improvements of catalytic activities after the addition of Ce. One is the increase of the thermal stability of Ni-B and Ni-P nanoamorphous alloys, which retards the nanocrystalline Ni to aggregate during the exothermal reaction of benzene hydrogenation. The other is to make their grain sizes smaller, thus it increases the number of activity center in unit mass.

说明加入Ce提高催化活性的主要作用有两方面，一是提高Ni-B和Ni-P纳米非晶态合金的热稳定性，抑制催化苯加氢反应时大量放热促使纳米晶Ni的聚集长大；二是使生成的Ni-B和Ni-P纳米非晶态合金颗粒更为细小，从而增加单位质量样品的活性中心数量。

Color-bearing scales are reduced to fine hairs, making the wings transparent except for four eyelike dots.

这种蝴蝶翅膀上的那些带有颜色的鳞状物都转变成了细小的绒毛，使得整个翅膀除了那四个眼状的斑点以外其他部分都是透明的。

The results showed that the elongated fibriform microstructure of Ti-Ni based alloys was obtained when the first preheating temperature was 850℃and the second was 750℃. After annealing at 400~600℃, the fibriform microstructure of the alloys was restored and refined microstructure was obtained.

结果表明：钛镍基合金经过850℃第一道次挤压和750℃第二道次挤压后，形成了细长的纤维状组织；经400～600℃退火处理后，其纤维状组织得到回复，形成细小组织。

The results show that the effectiveness of Route A is better than Route B. After ARB of 7 passes, the microstructure of the specimen by Route A consists of thin elongated fibriform grains with an average size of 470 nm, but that by Route B does compressed grains with an average size of 680 nm. The improvement in tensile strength by Route A is greater than that by Route B. The strengthening mechanism of 1060 commercially pure aluminum by ARB is fine-grain strengthening.

结果显示：路径A的晶粒细化效果比路径B明显；ARB7道次后，采用路径A的试样的显微组织由拉长的细小纤维状晶粒组成，路径B的试样由扁平状晶粒组成；路径A和路径B的试样的平均晶粒尺寸分别为470nm和680nm；路径A的试样的抗拉强度提高程度大于路径B.1060工业纯铝在ARB过程中的强化机制主要是细晶强化。

A part of the flat fibers remained on the sheet surface and the interspace among the fibers became narrow after chlorine dioxide bleaching. The fibers of bagasse and bamboo unbleached pulps were rough, the fiber surface was smooth, and the fiber structure was dense. After oxygen delignification and chlorine dioxide bleaching, the fibers became much more thin, the fiber surface was slightly fibrillated, and the fiber structure was loosen.

经氧脱木素后，纸页表面细小纤维明显减少，纤维间空隙较多，而经二氧化氯漂白后的纸页表面保留了一部分形态扁平的纤维，纤维间空隙相对较少；蔗渣和竹子未漂浆纤维较粗，纤维表面光滑，结构密实，而经氧脱木素和二氧化氯漂白后，纤维明显变细，纤维表面轻微帚化，结构较疏松。

Under the melting condition, floccular fibril is made via external force and blow.

在融化状态下，借助外力，吹制式甩成絮状细纤维，纤维和纤维之间为立体交叉，互相缠绕在一起，呈现出许多细小的间隙。

Under the melting condition, floccular fibril is made via external force and blow.The fly-over crossing is taken on between fibers and then they are intertwined . Thus many fine gaps are showed out.

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
