The energy flux density of the light wave decreases with the times of vibration in a unit time while decreases with the number of wave (caused by the increase of the wavelength) in a unit volume (unit length for plane homochromatic waves).

光波的能流密度一方面会随单位时间内波振动次数的减少而减小,另一方面会随单位体积内(对单色平面波就是单位长度内)波的数目的减少而减小。

The difference between isentropic and non-isentropic flows was studied as a development of Kage's work.

作为Kage等人研究工作的拓展,重点研究了隧道内非等熵流与等熵流间的差别。

The femoral circumflex arteriography of the normal leg was done in 8 patients, and three of them were simultaneously done in a postion of internal rotating of straight leg. Results Comparison with the arteriographic findings in absence of traction, all retinacular arteries but inferior arteries were depicted few branches and less femoral head perfusion in all 9 patients, especially in that of medial femoral circumflex arteriography, as hip joint was tractating in neutral position with the same speed and volume of injecting contrast medium and, the veins were demonstrated poorly or delayed.
