3.15 should be the day I pump my tires of my bike but I was in quite chaos and fatigue. So five days ago I did but failed because of the loss of the 表 of the pumper. Yesterday I brought the one in my house home that has one all the way back to school, car, train, car, bike.I should do the gas pumping today. Planned to pumper every half month but today is March the thirtieth. #log
Last night the tomcat's catalina console intrugerred me, it's almost only can change it to output in encoding gbk. And maven and java library upset me. The way I imported mysql connector java 8.0.28 was wrong in pom.xmlm but I don't know why. Only change version ID to 8.0.33.
极限算出来的,就是这个极点pole单独贡献的强度。因为所有极点互不重叠,把这些只在各自极点爆炸的简单分式加起来,它们在所有点的行为,刚好和原函数一模一样。再抽象一层,原函数 = 所有极点的效应叠加,留数 = 每个极点单独的效应大小,留数法 = 把每个效应单独测出来,再拼回去,测出来的特殊值(留数residue)拼起来 = 原函数的等价裂项式partial fraction decomposition #日记
