for example, the simultaneous multiple wavelength observation of certain pulsars help astronomers to more precisely determine their radiation emission mechanism
例如利用这观测法来观测脉冲星，可帮助天文学家确定其辐射发放机制。
an even more aggressive tool that astronomers are currently using is to observe an object in different wavelengths at the same time, known as simultaneous multiple wavelength observation
目前天文学家已掌握更先进的工具，能同时对天体的不同波段进行观测，这种方法称为同时多波段观测法。
3 ) the new types of photonic devices based on sampled grating : multiple wavelength laser, wavelength multiplexer / demultiplexer, reconfigurable optical add / drop multiplexer, optical fiber sensor, and multiple channels dispersion compensator
3)取样光栅构成的新型光子学器件：多波长激光器、波分复用解复用器、重构型光分插复用器、光纤传感器及多信道色散补偿器在光纤通信中的应用前景。
experimental results on butane and butane-plant oil flames indicated that, measurement precision by the multi-wavelength method is strengthened by taking radiation information on multiple wavelength units into consideration, and moreover, the radiation calibration procedure is simplified, in that a halogen light source is used instead of in situ flame radiation . in section 2, fluctuation and averaging analyses are carried out on optical transmission signals by particles passed through laser beams to derive particle size and concentration in measuring area, furthermore, correlation calculations are conducted on two adjacent laser beam signals to obtain flowing velocity of particle
对丁烷气体火焰及丁烷-植物油混合燃料火焰的测量结果表明，多波长分析方法优于传统的双色法，表现在两个方面：一、由于综合考虑多个波长单元上的火焰辐射信息，多波长方法的测量精度比双色法有较大的提高；二、在多波长分析方法中，采用标准卤素灯进行相对辐射强度标定，简化了双色法中的火焰绝对辐射强度的标定。
