无气孔的

The results show that the composite coatings have better metallurgical bond to the substrate, both crack and air hole are not found.

结果显示，合金层与基体成良好的无裂纹气孔的冶金结合。

The characteristics of clonal growth and resources sharing were important to keep stability of community. The transpiration and the stomatal conductance of stolon with and without adventitious roots were same. But the water potential of stolon without adventitious roots was higher than that with adventitious roots.

臭柏克隆生长和资源共享特性在维持群落稳定中起着重要作用，来源于同一上级枝的匍匐茎，有不定根的和无不定根的日平均蒸腾速率和气孔导度没有差异，但无不定根匍匐茎的叶水势比有不定根的高。

Annual production capacity of 200,000 pieces of their products with "no pores, trachoma" characteristics.

年生产能力200000余件其产品以"无气孔、沙眼"的特点。

Production of castings without trachoma, no pores, smooth texture, and reach the national standard by the manufacturers at home.

生产的铸件无砂眼、无气孔、平整光滑，材质好，达到国家标准，深受厂家的好评。

The experimental results show that the clad coating iscontinuous, homogeneous, poreless and crackless by optimizing the technical parameters.

结果表明，在优化工艺参数下可获得连续、均匀、无裂纹和气孔的熔覆层，熔覆层由TiC，γ-Ni，M236，CrB，Ni3B等相组成。

A Ni-Cu based cladding was thus deposited, where the powdered Ni1015 was provided for the laser cladding process to form a smooth surface layer bonded metallurgically with Cu substrate, whose grain-refining microstructure is homogeneous, compact, void-free and crack-free.

用5 kW CO2激光器，通过优化激光工艺参数，在结晶器用铜合金表面预置添加SiC晶须的镍基自熔合金(Ni1015)粉，制备出表面平整、组织均匀致密、无气孔和裂纹等缺陷、与基体为冶金结合的Ni-Cu激光熔覆层。

The tensile specimens all ruptured in the fusion zone and the porosities were absent.

拉伸试件的破断位置皆位於焊道区，且断口皆无气孔存在。

The two species are similar in stomatal character and in the absence of accessory transfusion tissue, but they are very different in stomatal distribution, pinna venation pattern and pinna marginal shape, presence or absence of mucilage canal, differentiation of palisade and spongy parenchyma, characteristics of girder parenchyma and epidermal anticlinal wall.

两个属在气孔器特征与不具副传输组织方面极为相似，而在气孔的分布、羽片脉序式样与叶缘形态、粘液道的有无、海绵组织与栅栏组织的分化、工字厚壁组织与表皮细胞垂周壁特征方面则有较大的差异。

Annual production capacity of 200,000 pieces of their products with "no pores, trachoma" characteristics.

年生产能力200000余件其产品以&无气孔、沙眼&的特点。

The results showed that the plant had the character of damp-inhabiting, the cutical on the epidermis of stem and leaf is rather thin but without wax-layer, its stomata protrude clearly on the lower surface of leaf, the rate of palisade parenchyma and spongy parenchyma is rather low and the cortex is well developed in root.

结果表明蓝靛果具有明显的湿生特征：茎、叶表皮的角质层薄，无蜡被；叶片上表皮细胞甚大，无气孔，下表皮细胞小，气孔明显突起；叶脉导管直径小，壁薄；叶肉栅栏组织/海绵组织小；根的皮层发达，富细胞间隙。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
