    It is well known that, the observed redshift of the farthest quasars has not exceeded 3.85 as yet, but the cosmic background measured in the microwave and millimetric region provides information mainly for very early periods at z-1000. What would happen in the redshift's region between 3.85 and 1000? And what extragalactic background exist in the region 1<λ<103 μm? The detection of such a radiation is considered as one of the main tasks of infrared astronomy in the eighties, because the investigation of its properties will provide precious information of astrophysical and cosmological interest. The discovery of IR background in the waveband 2-5 μm support this idea. In this paper we will investigate the radiative spectrum of the dust, heated by population Ⅲ. Because the radiative spectrum of the dust just occur in this region, 1 μm<λ<1000 μm.On the basis of the works of Carr. B. J. (1983), and Xie Guangshong (1984) We have obtained following results:(1) if there is no absorption above the Lyman frequency, the stars (VMOs) began to form at 2 = 100, and the number density of dust at present time is ng(t0) = 10-22 cm-3. The equation of radiation equilibrium for the dust takes form(2) If there is a Lyman cut-off, the stars bagan to form at z = 54, and the number density of dust at present time is ng(t0) =3×10-22 cm-3. And the equation of radiation equilibrium for the dust takes formwhere Bv*(T3) is blackbody spectrum, modified for Lyman absorption.Solving equations (1) and (2) respectively with various z and ng(t0),we have get temperatures of the dust at present time, as follows:by use of these temperatures of the dust at epoch to, we have calculated the radiative intensity of dust at the present epoch respectively and have plotted the results in Fig, 1, From Fig. 1, we can get mainly following conclusions,(1) If there is no absorption above the Lyman frequency, the radiative intensity of dust is very strong and it must distort the spectrum of the cosmic microwave background. And the radiative spectrum of dust can be detected in the waveband 200 μm<λ<1000μm.(2) If there is a Lyman cut-off, the radiative intensity of dust is very small (the curve-c of Fig. 1), thus it can not distort the spectrum of the cosmic microwave background. And it can not be detected in waveband 200 μm<λ<1000μm in this case.(3) Whether the results are correct or not can be verified directly by the observations.

    本文根据星族Ⅲ在有Lyman截止和无Lyman截止情况下,分别讨论了被星族Ⅲ(形成星系前的大质量恒星)加热的尘埃的辐射谱。利用数值积分方法,我们得到了尘埃在这两种情况下的辐射谱曲线。主要结果是:(1)如果星族Ⅲ的辐射谱无Lyman截止,即中性氢含量很少,尘埃的辐射将是很强的。它必将使宇宙微波背景在峰值附近产生0.1—0.3K的畸变,而且一定能在100μm<λ<1000μm波段被观测到。(2)如果星族Ⅲ的辐射谱有Lyman截止,即其内的中性氢的含量很大,这时尘埃的辐射与微波背景相比是极其微弱的,显然它不会使宇宙微波背景产生畸变,而且也不可能被观测到。因为它已被宇宙微波背景所掩没。(3)利用气球或卫星进行200μm<λ<1000μm波段的搜索,以判断上述两种情况何者正确,从而得到宇宙学的一些重要信息。
