自己今晚踢得不多,但是感觉一传成功率还行,基本上没有二传,发球还可以,要稳定要稳定,一传要到位。
开始有点累,似乎是懈怠心理在作怪,经过抖擞精神后,一切都好多了,加油!

slip flow and free molecule flow
Eckert, E. R., and Drake, R. M., 1987, Analysis of Heat and Mass Transfer, Hemisphere Publishing Co., New York, NY.
Page 481
Another interesting, and at the same time surprising conclusion, which has almost always been obtained in slip-flow analyses is that the results are found to correspond closely with free-molecule-flow results if the Knudsen numbers are taken as very large. Since slip flow is a phenomenon supposedly related to small Knudsen numbers, the exact significance of this correspondence to free-molecule-flow results at high Knudsen numbers is unknown; however, successful use of the correspondence has been made in semiempirical analysis to correlate experimental data over the entire flow regime form gas dynamics to free-molecule flow
