autunite

The content of autunite is between 2% to 4%, and the content of phosphor is over or equal to 0.8%;The content of salt is between 3% to 7%.

其中粗蛋白质含大35％，粗纤维小2O%，粗灰分小15％，含2．0-4．O％，总磷大0．8％，食盐含3．0-7.0%。

But an unexpected fact was noted: certain minerals( pitchblende, chalcolite, autunite) had a greater activity than might be expected on the basis of their uranium or thorium content.

但是一个意外的事实引起了我的注意：某些矿物质(青矿物质、云母云母)活性比根据其针含所判断的要高。
