吸收区的英文

例句与用法

1. The results indicate that with increasing the thickness of fes2 thin films , the electrical conductivity , the carrier concentration and the absorption coefficient decrease
   结果表明，随着薄膜厚度的增加， fes2的电阻率升高，载流子浓度下降，在高吸收区fes2薄膜的光吸收系数也呈下降趋势。
2. The natural red jadeites can be easily identified from dying and heat - treated ones by infrared spectrum . the natural ones contain water which represents absorbing apices on the area of 1500 - 1700 cm - 1 and 3000 - 3700 cm - 1 , while dying ones and heat - treated ones are not
   利用红外光谱可以准确地鉴别天然红色翡翠、染色红色翡翠和烧制红色翡翠，天然红色翡翠中有水的存在，在1500 - 1700 cm ~ ( - 1 ) 、 3000 - 3700 cm ~ ( - 1 )有强的吸收区，而染色翡翠和烧制翡翠中不含水，在以上区域没有强吸收。
3. The absorption is ascribe to physical absorption . silane combines with h of hydroxyl on surface of sericite , the absorption is ascribe to chemical absorption . in silane and stearic acid cooperation modification , c = o absorption peak appears in spectrum and the regional vibration of si - o - si becomes wide , which shows the physical absorption of stearic acid and chemical absorption of silane produce an effect on surface of sericite
   采用红外光谱对绢云母改性机理进行分析，结果表明，硬脂酸改性绢云母吸附强度较弱，容易脱附，以物理吸附为主；硅烷改性绢云母，与绢云母表面的羟基形成氢键，以化学吸附为主；硅烷与硬脂酸复合改性，其光谱中出现了c = o键特征吸收峰，并且si ? o 、 si ? o ? si振动吸收区变宽表明复合偶联剂在绢云母表面既有硬脂酸的物理吸附，又有硅烷的化学吸附。
