Each wavelength of optical radiation has an associated threshold retinal exposure level that must be exceeded in order for retinal damage to be observed - shorter wavelengths are more effective in that less energy is needed 对应每种波长的光都有一个极限值,超过这个极限值才能使视网膜受到损害.对于较短波长的光幅射,这个极限值的能量强度较低
This text also points out that the true intention is not attracting mncs ’ r & d centers proper but exerting mncs ’ r & d centers ’ driving and radialization function on china ’ s economy and technology 本文还指出,引进跨国公司研发机构本身不是目的,最终目的是充分发挥这些研发机构对中国经济和科技创新的带动作用,使其成为真正意义上具有幅射作用的研发中心。
In accordance with the recommendation for the practical realization of the above definition of the international committee of weights and measures , the laboratory maintains the metre through the wavelength of the 633 nm radiation from an iodine - stabilized helium - neon laser 按国际计量委员会对实现米定义的建议，本所透过碘稳频氦、氖激光器放出波长633nm的幅射以达至拥有米的标准。
