求翻译：用移液管准确量取10mL冰醋酸与水的混合液（冰醋酸与水以1:19的体积比相混合），放入分液漏斗中，用30mL乙醚萃取。注意近旁不能有火，否则易引起火灾。加入乙醚后，先用右手食指的末节将漏斗上端玻璃塞顶住，再用大拇指及食指和中指握住漏斗，这样漏斗转动时可用左手的食指和中指蜷握在活塞的柄上，使振摇过程中玻璃塞和活塞均夹紧。上下轻轻振摇分液漏斗，每隔几秒钟将漏斗倒置（活塞朝上），小心打开活塞，以平衡内外压力，重复操作2~3次，然后再用力振摇相当的时间，使乙醚与醋酸水溶液两不相溶的液体充分接触，提高萃取率，振摇时间太短则影响萃取率。是什么意思？

With the accurate amount to move fluid from 10 mL acetic acid and water ice mixture with water (ice-acetic acid in a 1:19 of the volume than the hybrid) and put in the sub-level in the funnel, with 30 mL ether extraction. Note that there is a fire nearby, and cannot be otherwise easy to cause a fire

Pipette accurately volume 10mL of glacial acetic acid and water mixture (glacial acetic acid is mixed with the water volume ratio of 1:19),%
