This article introduces key process of head forming , quality control of the cladding , zirconium surface protection and quality inspection to guarantee the corrossion resistance of the zirconium and mechanic performance of head 介绍了锆钢复合板质量控制、封头压制工艺、锆材表面防护、质量检验等几个关键工序要求，既保证了锆复层的耐腐蚀性又使封头具有一定的综合力学性能。
To improve the level of engineering harness , the author redefines the evaluation of rock slope crushing level ( rock mass quality ) , and divides the evaluation into two parts . one is the designation of surficial rock mass quality evaluation , which provides references for surficial harness of rock slopes . the other is the designation of integral stability rock mass quality evaluation , which provides references for the integral stability reinforcement 立足于工程治理，作者将岩质边坡的破碎程度(岩体质量)评价分为两部分，一是为岩质边坡表面防护治理提供依据的“岩质边坡表面岩体质量评价指标” ，简称为“表面rqd指标” ；二是为岩质边坡整体稳定性工程加固处治提供依据的“岩质边坡整体稳定性岩体质量评价指标” ，简称为“整体rqd指标” 。
The investigation of a lot of parameters about treated sandstone , brick materials and earthen materials with fluorited polymers has been carried out , such as the formation of polymer , the penetration depth , porosity , capillary absorption and penetration coefficient , water uptake , compressive strength , drilling resistance , absorption isotherms of water vapor , water vapor diffusion , color changes as well as resistance to desegregation of water , frizzing - throwing cycles , worming - cooling cycles , and so on . in addition , the influence of salt crystallization , acid and base , and uv aging have also been assessed in order to better understand the protection effects and utilization possibility of two fluorinated polymers , mainly according to astm standard and the combination of international methods together with general technological 分别以国家级文物保护单位的土质、砂岩和砖材文物样品为对象，依据astm标准及国际通用文物保护研究方法与评估准则相结合，通过胶化物形成周期、渗透深度、孔隙度、毛细吸水和渗透系数、持水量、抗压强度、抗钻强度、吸附水蒸气的能力、透气性、外观颜色等系列参数的测定，及冻融、冷热循环、酸碱腐蚀后抗压强度的衰减、可溶盐对保护效果的影响、酸碱及光照对表面保护效果的影响，对两种含氟聚合物及其与有机硅的共混物在文物加固保护和表面防护中的可行性和保护效果给予了系统研究。
