As contraction continues and the density increases, the dust becomes so thick at the center of the cloud that it absorbs the far-infrared radiation . 当收缩过程继续进行下去,密度不断增大时,气尘云中心的尘埃就会变得极其浓密,因而能够吸收远红外辐射。

Adopt far - infrared heating technology , with low hot loss , high efficiency , high precisely for control temperature , uniform heating . compared with drying cabinet or electric stove ; it can automatical control temperature , easy to operate , drying effect is very satisfied 采用了远红外辐射加热技术,与一般烘箱及热处理用的箱式电炉相比较,具有热损失小、效率高、控温精度高,加热均匀:能自动控温、一时结束、操作方便等优点,可达到十分满意的烘干效果。
To understand the connections between methanol masers and other phenomena typical of star formation region , such as the associated far - infrared sources , we have investigated statistical properties of all known 6 , 7 ghz methanol maser sources . the result suggests that 6 , 7 ghz methanol maser emission may appear only during a limited period of massive star formation 6 . 7ghz甲醇脉泽源的统计结果暗示着它们可能仅仅发生在大质量恒星形成的一个很短的时段内,可能起源于拱核盘中或外流中,远红外辐射则是一种可能的抽运机制。
