bt1bt2btc是啥

① APT1,APT2,APT4是什麼意思啊。MMT1.MMT2,BT1.BT2什麼意思

CAS號62001-29-0的名稱和物化性質如下：
英文名稱 N-(benzotriazol-1-ylmethyl)aniline
英文別名 N-phenyl-1H-benzotriazolyl-1-methanamine;BIDD:GT0675;N-,mixture of Bt1 and Bt2 isomers;(benzotriazolylmethyl)phenylamine;N-(1H-benzotriazol-1-ylmethyl)aniline;N-((1H-benzo[d][1,2,3]triazol-1-yl)methyl)aniline;1-[(Phenylamino)methyl]benzotriazole;N-Benzotriazol-1-ylmethyl-anilin;N-benzotriazol-1-ylmethyl-aniline;
熔點 137-143ºC

② Java Swing（初學者）：有6個文本框豎直排列和兩個按鈕(bt1和bt2)，默認焦點在第一個文本框上。

以前寫的，功能差不多，用1，2，3，4。。代替了。自己看一下吧
ctrl+1表示選擇編號為1的按鈕。上下鍵控制位置變化
