一、设计的指导思想松香颜色的测定可以采用目视法和光电法。目视法是现在国内所采用的方法。所使用的仪器是英国出品的罗维邦色调计及美国标准玻璃色块。由于目前国内一时尚不能解决罗维邦色调计的色片或者美国标准玻璃色块,因此在设计时,这种方法就不去考虑了。遵照毛主席“独立自主”、“自力更生”的伟大教导,根据我厂经验,采用光电法所有的原材料和元件都可以立足国内,因此设计时,采用光电法来设计仪器。
First, the design guidelines Rosin color determination can be used visual method and photoelectric method. Visual method is now used in the country. The instrument used is the British production of Rovibang tones and the United States standard glass color block. Due to the current domestic fashion can not solve the color of Rovibou color meter or the United States standard glass color block, so in the design, this method will not be considered. According to Chairman Mao’s “great independence” and “self-reliance”, according to our experience, all the raw materials and components using optoelectronics can be based on the domestic market. Therefore, the design of the instrument is based on the photoelectric method.
