LIU Dawei, YAN Ailing (The science and engineering College of Gansu Association University .Lanzhou 730000)
A supposihion which is "During the raindrop extremc speed have not achieved,the raindrop accederation is progressive decrease evenly."was proposed.According to this supposition,and use rnown raindrop extreme,the raindrop monement which during the raindrop extreme speed have not achieved was analysed. According to this supposition which is decreased progressively when the raindrop achiered in front,the final rate o frain drop has been obfained.
