5．样槽必须保持干净，使用后用蒸馏水冲洗，洗后倒置避免粉尘进入。

5 slot must be kept clean after use, rinsed with distilled water, after washing to avoid dust entering the inversion.

6．水样加入样槽，不要让气泡进入，脱泡方法为静置一段时间。

6 water adding sample bath, don't let the entry of air bubbles, defoaming method for a period of time.

7．玻璃样槽放入样槽座时，应把玻璃样槽上有标线的一面面向操作者。
