Comparing with Viburnum opulus, the differentiation of leaf construction, the distribution and density of stomata, trichome and glandular hairs, the characteristics of cutin and cuticular ornamentation were studied as well.

蒾蒾利用光镜和扫描电镜观察了蒙古荚的叶片表皮形态和解剖结构特征，对比欧洲荚，对其叶片结构的分化、气孔器与表皮毛、腺毛的密度和分布、角质层及蜡质纹饰等特征进行了研究。

The results showed that:Under NaCl stress,the reductions in the shoot and root dry weight, leaf area,stem diameter of grafted plant were lower than those of ungrafted plants.The Na~+ content,Na~+/K~+ ratio,Na~+/Ca~(2+) ratio in the leaf and scion stem of grafted plants were lower whereas those of in the rootstock stem ad root were higher than in ungrafted plants. The K~+ contents,soluble sugar contents,shoot water contents,SOD,POD,CAT,APX activity,the stability of AsA/DHA,Photosynthetic rate,transpiration rate and stomatal conductance were higher,whereas the MDA contents in the leaf of grafted plants were lower than that in ungrafted plants.The reductions in leaf area and stem diameter of grafted \'Jinchun No.2\' plants were more severe than those of grafted \'Zaoduojia\' ones.

结果表明，盐胁迫下，嫁接苗地上部和根干重、叶面积、茎粗降低的程度显著低于自根苗；嫁接苗叶片和接穗茎中Na~+含量和Na~+/K~+、Na~+/Ca~(2+)比值显著低于自根苗，而砧木茎和根中的Na~+含量和Na~+/K~+、Na~+/Ca~(2+)比值显著高于自根苗；嫁接苗叶片中K~+含量、可溶性糖含量、地上部含水量、SOD、POD、CAT、APX活性、AsA/DHA的稳定性、光合速率、蒸腾速率、气孔导度显著高于自根苗，MDA含量显著低于自根苗。

In addition, there are bond areas between the new and the primary coverage because of the growing up of the plating coat, which may lead to the emergence of micro crack on the coating owing to such causes as too big or uneven impact during plating process, little distortion of global granular zinc dust inside the plating coat, less tight coalescence of the zinc dust flecks.

由于形成镀层的过程处在酸性环境，在镀层增厚过程中不可避免把酸性溶液包裹在镀层里面，酸性溶液会与金属基体和镀层反应，产生氢气，必然会寻找通道选出，形成微气孔；镀层是逐渐形成的，新生镀层与原有镀层之间存在结合面；镀覆过程由于撞击力过大或者不均匀，镀层内部球形颗粒状锌粉变形较小，球形颗粒与球形颗粒的结合不严密等，这些原因会导致镀层产生微裂纹。

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。
