寻找更加安全的鞣制方法一直是制革行业的研究方向。由于在水溶液中与Cr（Ⅲ）具有相似的化学性质，Fe（Ⅲ）盐常常被认为是一种可能取代铬盐的鞣剂。但是，在制革工业中使用Fe（Ⅲ）鞣法，仍然存在一些局限性。其中一个主要问题就是铁鞣法不能用来生产软革，例如服装革、手套革。为了克服该问题，本文尝试用铁鞣法来生产山羊绒而和绵羊纳帕服装革。试验优化了铁-铬结合鞣法，同时将鞣制废液中铬和铁的含量部降低到了100mg／L以下。为了研究铁-铬结合鞣法对皮革结构的影响，本文采用了扫描电子显微镜对鞣革进行分析。另外，对鞣革的强度和颜色特征也进行了表征和分析。

The comparison between experimental and theoretical heat transfer inside heated vertical channels that dissipate heat from the internal surface with and without internal rings is *** experimental setup consists of a circular pipe which is heated electrically by providing constant heat flux on the *** theoretical and experimental analysis is conducted in several pipes of same diameter but different *** length of the pipe varies from 450 mm to 850 *** length to diameter ratios are taken as L/D=10,12.22,15.56,and *** value of imposed heat flux varies from 250 to 3340 W/*** internal ring thickness varies from 4 mm to 8 *** distance between the internal rings varies from 75mm to 300 *** theoretical results are compared with experimental data to ascertain numerical accuracy of the *** effects of L/D ratio,thickness of internal rings and separation distance on the heat transfer performance are *** experimental result is compared with theoretical,theoretical results are found by using *** this study theoretical result for wall temperature along the height of tube,fluid temperature at exit of tube are compared with experimental data.
