The effect of reflection radiation, radiation of the detector itself,the surrounding temperature,the selective absorption gas in optical path, and other factors on temperature measurement accuracy for a practical temperature measurement system were discussed based on a practical dual-wavelength fiber-optic colorimeter using LiTaO_3 pyroelectric detector.
Combined with the problems in maintenance of transmitter & receiver of railway dispatching radio set,this article described several interference phenomena ,such as noise of transmitter,radiation of mixed wave radiation,radiation of adjacent wave power,commutative disturbance,and receiver blocking,and analyzed the mechanism of their occurrence. Specific solutions and their feasibility were brought forward.
The results indicated that :the decrease of the heat balance ,total solar radiation,radiation balance and effective radition is inversely proportional to the intercropping rowspacin5 ×40～5 ×50 (m)models among all intercropping models received the bestbenefit.
The results demonstrated that the inhibition rates of tumor were 69%,22% and 1% in DE—03 and radiation,radiation,and DE—03 group,respectively,ratio(E/O) was 2.57.Electron microphotograph examination showed that radiation combined with DE—03 could increase damage to tumor cell ultrastructure (mito- chondria membranea)without any damage to the normal tissue; suggesting that DE—03 may be a radiosensitizer.
In the paper the latest physical and biologic preserve technology(including ultrasonic, ultraviolet radiation , radiation and nisin etc.) of the soy are summarized in order to producing enterprise of the soy reference.
radiodurans' desiccation tolerance could be a consequence of this organism's adaptation to ionizing radiation (radiation adaptation hypothesis), should be considered on equal basis with the "desiccation adaptation hypothesis".
The cosmic background radiation--radiation which fills the entire universe--is a relict of that explosion.
Scattered radiation Radiation that, during its passage through a substance, has been changed in direction.
Secondary Radiation Radiation emitted by any matter being irradiated with X-rays.
Non-ionizing radiation--Radiation lacking the energy to remove tightly bound electrons from their orbits around atoms.
