A data acquisition and analysis system of insect acoustic signal ( daasias ) with friendly interface , simple operation and multifunction was developed . it could sample and analyze insect acoustic signals in real time . by daasias both observing insect behavior and analyzing signal could be conducted at the same time 以往昆虫鸣声信号是记录在磁带上，分析时通过回放磁带的录音，在示波器、频谱仪或声谱仪等声学仪器上进行信号分析，结果磁带的多次回放常会引起信号的失真，并难以对信号作进一步的编辑处理；分析仪器不但价格昂贵、体积较大，而且很难实现昆虫声行为观察与信号分析同步，更不适合野外工作。

Using the new technique , the zero , the first and the second differential pas of some persons " blood was measured , the result shows : the new technique is more sensitive than the common pas technique . the pas of many persons " blood has absorption peak around the wavelength of 637nm and 664nm 并用导数光声光谱技术测量了各种人血的零阶，一阶，二阶导数，实验表明：导数光声光技术比普通光声吸收光谱技术具有更高的检测灵敏度；许多人的血液的光声谱在637nm和664nm附近有吸收峰。

Different vocal behavior models were given from sound spectrum analysis for different songs . based on rule sonagram , quantitative analysis and qualitative analysis , difference comparative analysis in and between individuals for different songs were developed , and obtained the sresuls were as follows : ( 1 ) acoustic properties of male songs were that there were less syllables in every single calling song , it was usually more t 通过对不同鸣声的声谱分析，给出了不同鸣声的声行为模式，并在常规声图的基础上，对不同鸣声进行了定性与定量分析、个体内差异比较分析以及个体间差异比较分析，得出结果如下： ( 1 )雄性的鸣声特性是每个单次叫声中含有的音节数较少，一般不超过4个音节；而雌性的鸣声特博士学位论文摘要东北农业大学仿毁刨会次叫声？
