Cellular plastics , rigid - test methods for self - skinned , high - density materials iso 9054 : 1990 ; german version en iso 9054 : 1999 硬质泡沫塑料.自结皮高密度材料的试验方法
Building and construction sealants - methods of test for application life , skinning properties and tack - free time 建筑施工用密封胶.第3部分:使用寿命,结皮特性和粘性消失时间试验方法
Pam is able to cohere strongly the soil particles at the surface to form bigger aggregates , therefore to significantly increase infiltration and reduce soil erosion Pam能明显地黏结土壤表面的颗粒，形成团聚体，阻碍土壤结皮的形成，减少土壤侵蚀。
It was developed on the basis of investigation and a large amount of data . firstly , the article analyses and designs the net truss of automobile - maintenance industry 同时，还对乳化沥青的性质进行了探讨，特别是乳化沥青的结皮现象、蒸发残留物性质等。
The golden - mantled tree kangaroo is just one of dozens of species discovered in late 2005 by a team of indonesian , australian , and u . s . scientists on the island of new guinea 金色结皮树大袋鼠只不过许多种类用2005后期以一印尼，澳洲，和美国科学家的队发现，在新几内亚的岛上。
Crust significantly reduces soil infiltration rate and subsequently lowers the utilization of water resources , and increase runoff , which induce heavier soil erosion 封闭、结皮是土壤表面水土相互作用的结果，能显著减少土壤入渗、降低水资源的利用率，增加地表径流并导致土壤侵蚀。
The follow - up kinds of products which our company research and develop include : single - side - formed pvc board series ， single - side - embossed color board series ， pp ， pe ， abs ， pc board series 公司后续研发的品种包括： pvc发泡单面结皮、单面压花彩板等系列产品， pp 、 pe 、 abs 、 pc等系列板材。
To avoid jam , expansion bin and automatic - control blowing system and necessary compressed air devices will be adopted to guarantee normal running of pre - heater 为防止预热器系统结皮堵塞，除在旋风筒下设有膨胀仓外，还配有独特的自动控制喷吹系统以及必要的空气炮，保证预热器系统的正常运行。
From the changes in soil erosion upon the slope , the dynamic processes of runoff and soil erosion along slope was analyzed . with ree to trace the processes of soil erosion 结皮对土壤侵蚀的影响主要反映在径流造成的土壤侵蚀中，给出了结皮效应率的定义，并据此定量评价了结皮对土壤入渗、土壤侵蚀的影响。
