Through analyzing strata ' s absorbtion and attenuation , the specialty of ssf in system - one ( two ) and 24 - bit a z a / d , the scheme to improve the data acquisition system is brought forward including the design of multiple differential spectrum equilibrium filter ( mdsef ) and program control amplifier
通过详细分析地层的吸收衰减特性， system - one ( two )频谱整形滤波器及24位a d的特点，对现有采集系统提出了改进方案。其中包括对多级微分频谱均衡滤波器的理论设计，程控型前置放大器的理论分析与设计。
In the last part , the differential pas technique , which combines the pas technique with the differential spectrum , overcomes the defect from the two techniques , making it has the both advantage of the pas technique , which is suitable for the measurement of the heavy diffusion > opacity sample , and the advantage of the differential spectrum which is capable of differentiating the overlap spectrum and shoulder peak , is present
第三部分提出导数光声光谱技术，将光声光谱技术和导数光谱结合起来，使导数光声光谱技术同时具有光声光谱技术的可适用于强散射，非透明的样品测量和导数光谱可分辨重叠光谱，分辨肩峰的优点，又克服各自的缺点。
