1. Comments: This is a very reliable valve for non-corrosive and high purity products. However, the design makes this valve inappropriate for corrosives and ultrahigh-purity products. 评论：对于非腐蚀性和高纯度产品，这是一种非常可靠的阀门。但是，它的设计使得它不适合用于腐蚀物和超高纯度产品。
2. Saturation refers to the purity of the color, if a mass spectrum in a light reflectance high, and on other band of light in a very low reflectivity or not, this color purity. 饱和度是指颜色的纯度，如果一物体对光谱中某一波段光的反射率高，而对其他波段光的反射率很低或没有，则此色的纯度就高。
3. High purity titanium sesquioxide was obtained by the reaction of high purity hydrogen and titanium dioxide in the presence of titanium tetrachloride. 用高纯氢和高纯二氧化钛，在四氯化钛存在下，可以得到高纯三氧化二钛。
4. Comments: This is a very reliable valve for non-corrosive and high purity products. However, the design makes this valve inappropriate for corrosives and ultrahigh-purity products. 评论：对于非腐蚀性和高纯度产品，这是一种非常可靠的阀门。但是，它的设计使得它不适合用于腐蚀物和超高纯度产品。
5. also known as saturability, is the same purity of tone color purity. 饱和度也叫纯度，是同一色调中颜色的纯度。
