文中介绍了试验羊肠线在酵素里消化时间的方法和含铬量的化学测定法。实验指出,因鞣制方法的不同,铬鞣羊肠线的含铬量和它在酵素里消化时间的关系,很不一致。但是若用同一方法鞣制,含铬量和消化时间是有一定关系的。所以羊肠线制造者可以采用化学定铬含量的方法来作为掌握制造过程和制品性能的一种依据。 This article describes the method of digestion time of the gut in the enzyme and the chemical determination of chromium content. The experiment pointed out that due to the difference in tanning method, the chromium content of the chromic gut gut was very different from its relationship with the digestion time in the enzyme. However, if you use the same method to make, there is a certain relationship between the amount of chromium and digestion time. Therefore, gut gut makers can use the chemical chromium content method as a basis to grasp the manufacturing process and product performance.
