Galactosidase can hydrolysis a -galactosis bond , namely it can hydrolysis galactosis complex of non-reductive ends binding α-bond, so it can hydrolysis oligosaccharides such as raffinose、 stachyose、 verbascose, et al. It also can hydrolysis heteropolysaccharide including α-galactosis bonds.

能催化α-半乳糖苷键的水解，即能水解非还原性末端以α键结合的半乳糖苷化合物，因此它能水解蜜二糖、棉子糖、水苏糖和毛蕊花糖等低聚糖，还能水解含有α-半乳糖苷键的杂多糖。

Machining Tolerance is the permissible variation in actual space width or actual tooth thickness.

加工公差：加工公差是花键的实际齿槽宽和实际齿厚的允许的变动量。

I start modeling the snail shell, to do this I use a spiral spline and a circular shape inside a sweep NURBS, I activate it and adjust the spiral parameters to get both the necessary turns and the thickness at the beginning and at the end.

我开始建模蜗牛壳，为此我使用螺旋花键和一个圆形形状内打扫的NURBS ，我激活它，并调整螺旋参数，以获得这两个必要的转折和厚度在开始和结束时。

The tooth profile error and longitudinal form error are calculated,and the change rule with setting angle of them is got.

针对花键的齿形误差和齿向误差，按照误差计算原理，得出了计算结果及其随安装角改变的变化规律。
