查询词典 bands

When applying this instrument to observe or photo the bands of DNA and RNA, the distictness can be compared with that of same type instrument produced abroad and the shadow of the light tubes which is always appeared on the photofilm will be wliminated because the ultraviolet light with various wavelength is applied in this instrument.

Because the photospheric temperature of carbon stars are less than 3000K and the temperature of rich-dust envelope formed by the mass loss is lower, and therefore most of the energy from carbon stars are radiated between 1 to 60um range, in which the vibrational and ro-vibrational bands of many molecules also lies, the study of infrared spectra in this wavelength range is very important to reveal chemical compositions, dust formation process, the atmospheric structure and evolutionary status of stars.

碳星光球的有效温度不超过3000K，同时较大的质量损失率形成了富碳的尘埃壳层，以致于它的辐射能量主要集中在1—60μm的红外波段上，并且许多分子的转动振动能谱也集中在红外，因此在红外波段的研究对揭示碳星化学成份及其分布、尘埃形成过程、恒星大气结构和演化状态都有十分重要的意义。

In a 1997 interview, Plass told me,"all sorts of things came together" that placed him at the scientific forefront: new detailed laboratory measurements of the absorption bands of water vapor, carbon dioxide and ozone; theoretical developments involving the influence of temperature and pressure on infrared absorption; new information about the carbon cycle and industrial emissions; and access to a new high-speed electronic computer to facilitate complex calculations of radiative transfer that replaced the older, graphical approximations.

在1997年的一次采访中，普拉斯告诉我：&所有的事情都赶在一块儿&，把他推到了研究的最前沿：测量水蒸气、二氧化碳和臭氧的吸收光谱带有了新的实验方法；温度和压强对红外吸收的影响理论有了新的发展；碳循环和工业废气排放有了新的资料；新的高速电子计算机代替了老式的图解近似法，让辐射传热的复杂计算变得简单了。
