容量瓶

不确定度主要来自于重复性测定、天平、250mL容量瓶、25mL移液管、分光光度计及测定过程。

The main uncertainty ′ s resource were repetitive measurement , balance , 250 mL volumetric flask , 25 mL piper , spectrophotometer and its process of determination .

容量瓶温变试验及其应用

Test of the variation for the volumetric flask capacity according to the temperature

结果表明，以中高档功率微波浸提4min，基本可以浸提完全，用100ml的容量瓶浸提试样，浸提液体积为40~60ml时，结果较为理想。

Results showed that using the microwave with middle and high power to soak the dry fruit for 4 min can soak in full . Using the vase with 100 ml volume and the soaking volume of 40 ~ 60 ml to soak the samples can get good result .
