如果是病毒感染導致的發熱，是容易反**熱的，一般病程在一週左右。還是建議檢查血常規，瞭解感染情況，明確診斷，再對症用藥。注意多給孩子喝水。
其次，還有一種情況，就是如果有血象的升高，抗生素不能控制感染，也是有可能導致發熱的。所以還是建議先檢查血常規，瞭解感染的情況，對症用藥。
你好發燒是很多疾病都會有的症狀，一定要把引起發燒的病治好了，燒才能真正的退下來。如果還有咳嗽、流鼻涕等感冒症狀，需要用雙撲偽麻分散片、小兒氨酚黃那敏顆粒等感冒藥**。體溫在三十八點五度以上時，可用美林或泰諾林退燒**；體溫在三十八點五度以下時，或勤些用溫水擦浴以降溫，或用兵兵退熱貼敷額以降溫能起到退熱護腦的作用。

在vb中，如何編寫程式通過隨機函式產生10~99之間的隨機整數？

vb 產生隨機數的公式（上界-下界+1）*rnd+下界你的題目就應該是（99-10+1)*rnd +10一般用rnd的時候還要在前面加一條 randomize 初始化隨機種 子
