| 内容記述 | The NASA Infrared Telescope Facility has been used to observe local continuum brightness variations of the quiet sun in 350 and 800 micron radiation simultaneously. Variations of order 5 K are found at both wavelengths, with a strong correlation between the two. The 800 micron variations lag behind the 350 micron variations by 25-35 deg in phase. This is similar to unexpected phase shifts reported by Lites and Chipman in 1979 and Lites, Chipman, and White in 1982 between velocity and intensity for certain chromospheric lines. It is proposed that the phase lags observed are the result of nonadiabatic response of the chromosphere to compression, which could be an important mechanism for dissipation of mechanical energy. |
