2. The well-marked cases of hypochromatism that have been examined lack the power of discriminating between the colours bordering on the yellow, but they are extremely sensitive to differences in wavelength at about 4900 脜. There is no maximum in the region about 5800 A, and mistakes may ...
2.In this paper the plasma and measuring distances effecting on ultraviolet wavelength andrelative light intensityof the blue lights from its surface are discussed.介绍了2种不同等离子体发生区和不同测量距离对等离子体发生区沿面蓝光中紫外光的波长和相对光强的影响,所测的臭氧发生量大的等离子体发生区的紫...
Some experiments were undertaken to clarify the relation between light intensity and the relative photosynthetic rate of the intact leaves of potted mulberry trees. The photosynthetic rate was expressed as the percentage of photosynthetic rate measured under the light intensity of 52 Klux. The results ...
Physiological evidence shows that the light regime can influence the progression of sex in both centric and pennate diatoms, even though the presence of a suitable partner has generally been considered the primary requirement for sexual reproduction in pennates3. Studies assessing the effect of light...
light wavelength—have been observed for a variety of neat semiconductors (e.g. titanium (IV) oxide, cadmium sulphide, bismuth orthovanadate, etc.)9,10,11, but may be also induced by an appropriately designed surface modification with organic compounds (e.g. anthraquinone derivatives)12and/or ...
光照度与光强度（Light intensity and light intensity）Lux (Lux, legal symbol LX) as a unit of illuminance, the distance light intensity of LCD light source, illumination intensity, in 1 meters of Xi said: Candle Light. Rice. That is, the distance from the light source 1 meters, the area ...
To improve the sensitivity of the photodetector, it is very necessary to carefully consider the dark and photocurrent densities of the detector itself, which highly depend on the illumination conditions, i.e., the light wavelength and intensity and the OPD’s operating conditions. To understand ...
The unit for the quantity of light flowing from a source in any one second (the luminous power, or luminous flux) is called the lumen. The lumen is evaluated with reference to visual sensation. The sensitivity of the human eye is greatest for light having a wavelength of 555 nanometres (...
Examples of this kind, which were meanwhile also realized in the experiment6–10, are the unidirectional invisibility of a gain–loss potential11, devices that can simultaneously act as laser and as a perfect absorber12–14 and resonant structures with unusual features like non-reciprocal light ...
