Process(group, target, name, args, kwargs)
			group：指定進(jìn)程組，?多數(shù)情況下?不到
			target：表示調(diào)用對(duì)象，即子進(jìn)程要執(zhí)行的任務(wù)
			name：子進(jìn)程的名稱，可以不設(shè)定
			args：給target指定的函數(shù)傳遞的參數(shù)，以元組的?式傳遞
			kwargs：給target指定的函數(shù)傳遞命名參數(shù)

			p.start() 啟動(dòng)進(jìn)程，并調(diào)用該子進(jìn)程中的p.run()方法
			p.join(timeout):主進(jìn)程等待?進(jìn)程執(zhí)?結(jié)束再結(jié)束，timeout是可選的超時(shí)時(shí)間
			is_alive()：判斷進(jìn)程?進(jìn)程是否還存活
			p.run() 進(jìn)程啟動(dòng)時(shí)運(yùn)行的方法，正是它去調(diào)用target指定的函數(shù)
			p.terminate() ?即終??進(jìn)程
