Probably the best - known gauge of earthquake intensity is the local richter magnitude scale , developed in 1935 by united states seismologist charles f . richter 或许最著名的地震强度测量是区域里氏震级，是由美国地震学家查尔斯?里希特1935年确立的。
Our cosine correctors couple to optical fibers and spectrometers for relative and absolute spectral intensity measurements , for emissive color applications , and for evaluation of light sources such as leds and lasers 我们的余弦校正器可与光纤和光谱仪连接，用于相对光谱强度和绝对光谱强度测量、发射光谱测量，以及对led光源和激光光源进行评价。
