A color forming composition or composite can include a polymer matrix, a thermally modifiable fluoran leuco dye having a latent developer attached thereto, and a radiationabsorber.
成色组合物或复合材料可包括聚合物基质、潜在显色剂与其连接的可热修饰的荧烷隐色染料以及辐射吸收剂。
2
The assumption of constant relative humidity is important, because water vapor in the atmosphere is another efficient absorber of radiation at infrared wavelength.
相对湿度恒定的假设是重要的，因为大气中的水蒸气是红外波长辐射的另一种有效吸收剂。
3
The structure acoustic radiation caused by longitudinal vibration of shafting is reduced by changing excitation force propagation path and adopting vibration isolator or dynamic vibration absorber.
