今天的實驗真是悲慘
                                                                               
學姐說早上點火就很難點  後來就熄火了  是冷卻水過不去...
                                                                               
搞了很久  換了電磁閥...抽真空
                                                                               
中午我來了之後
                                                                               
看真空抽到10的-7了就點火  還是不行
                                                                               
問了警官才知道  要等他抽到3*10-7  再點比較好
                                                                               
於是就等等等等  快六點的時候
                                                                               
我發現真空跳掉了@@
                                                                               
接下來一段漫長點火+換電磁閥+抽真空的動作
                                                                               
重複了好幾次  終於成功了
                                                                               
現在他乖乖的在抽真空
                                                                               
希望他不要再鬧脾氣啦~~
