APPLICATION OF THERMODYNAMICAL RETARDED GREEN FUNCTION TO THE THEORY OF LINE WIDTH OF FERROMAGNETIC RESONANCE
MON SIAN-CHEN, PU FU-CHO
1961, 73 (5): 214-221. doi: 10.7498/aps.17.214
Abstract +
The theory of Clogston and his coworkers on the line width of ferromagnetic resonance is derived by using thermodynamical retarded Green functions. The results obtained are applicable for a wide range of temperatures. The susceptibility tensor and the cha
SOME PROBLEMS OF PHOTO-MULTIPLIER TUBES
LU KING, WANG TA-CHENG
1961, 73 (5): 229-236. doi: 10.7498/aps.17.229
Abstract +
This paper describes the fundamental problems of different types of photo-multiplier tubes for scintillation techniques, the relation between parameters of the multiplier-photo-tubes and their application. The status of photo-cathodes, secondary emissive
INTERNAL FRICTION PEAKS OBSERVED IN HIGH CHROMIUM STEELS AND HIGH CHROMIUM-NICKEL STEELS AT HIGH TEMPERATURES
KUNG CHING-PING
1961, 73 (5): 237-245. doi: 10.7498/aps.17.237
Abstract +
Several internal friction peaks were observed at high temperatures during torsion pendulum measurements in four types of high chromium steels and eight types of high chromium-nickel steels.An internal friction peak around 570℃ was observed in each of thre
