求翻译：The catalytic activities for the transesterification of rapeseed oil with methanol were measured by typical procedure [10]: a given amount of modified CaO and methanol were placed in a three necked round bottomed flask equipped with a reflux condenser and a thermometer. Then, the rapeseed oil was added into the mixture是什么意思？ 待解决

菜子油与甲醇的酯交换反应的催化活动，通过典型的过程[10]：一定量的改性CaO和甲醇在三颈配备回流冷凝器和温度计的圆底烧瓶中。然后，菜子油，加入混合物，并在一定时间一定温度下加热。反应结束后，在真空条件下蒸馏过量甲醇。由GC（HP-6890）使用内标准的产品进行了分析。产量被定义为脂肪酸甲基酯的重量比，气相色谱测定，脂肪酸甲酯的重量，在反应中所用的油，假设只有酯的痕迹被转移到极地阶段，只有甲醇和甘油的提取发生洛佩斯建议[16]。

transesterification的发挥催化作用的活动的芥花籽油与甲醇进行测量的典型过程[10]:有一定数额的修改曹和甲醇被置于一个圆底烧瓶三个着颈项配有一个回流冷凝器和温度计。 然后,添加了油菜籽油的混合物,在在一定的温度,加热一定时间。 反应完成后,将多余的甲醇关闭真空蒸馏。
