Optical absorption spectra and positron annihilation radiation Doppler broadening were measured at room temperature.
在室温条件下测量了吸收光谱与正电子湮没辐射多普勒展宽谱。
However, disturbances from inside and outside of the constant temperature room, such as infiltration air, the equipment radiation fluctuation will affect the temperature stability.
而恒温室内外扰量多有渗透风、设备散热量波动等，导致了其恒温稳定性很难达到预期效果。
