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?

10樓:匿名使用者

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

11樓:匿名使用者

randomize time '初始化

print int(rnd * 90) + 10 '產生隨機數,並輸出

12樓:匿名使用者

private sub form_click()randomize

for i = 10 to 99

n = int(rnd * i + 10)next

print nend sub
