1) Improvement of obscuring effect in middle and far infrared waves is the aim of study about combustion smoke-producing mixtures.

2) By near infrared waves to glue molecules produced vibration absorption accelerated glue dry.

3) As an example, the longer, infrared waves indicate temperature and , therefore , the possibility of life.

4) By far the larger part of the energy emitted, however, is still carried by infrared waves.

5) The reflection rates of spectra of the canopy decreased in the near infrared waves and increased in the visible waves with increasing the plant densities.

6) Our far-infrared heating element is low temperature carbon film which heats by emitting far infrared waves which can improve circulation of blood vessels of faces.

7) Some additives such as graphite, PTFE and CsNO3 can improve obscuring effect of smoke screening in infrared waves.
