2. The main results are shown as below : 1 . 80 individuals from 4 populations ( 20 from each population ) of argopecten irradians were analyzed by using 20 random rapd primers . 132 rapd bands ranging from 230 to 2800bp were recorded with an average of 6 . 6 bands gained by per primer
   采用20条随机引物对4个群体80个个体（每个群体20个个体）进行了rapd群体遗传多样性分析，共扩增出132个位点，片段大小在230 - 2800bp之间，平均每条引物的扩增带数是6 . 6条。
3. For phonetic signal modulation , if the pass band range of the band pass filter ( bpf ) is 300hz - 3400hz , the anti - noise properties of laser are approximately independent of bias current and parameters of the cavity ; when the pass band range of bpf increases to a certain degree , modulating bias current and parameters of the cavity can improve the anti - noise properties of laser
   对语音调制情况，如带通滤波器的通带范围取为300hz - 3400hz ，则激光器的抗噪声性能基本不依赖于偏置电流和腔内参数；当带通滤波器的通带范围增大到一定程度，调整偏置电流和腔内参数可以实现半导体激光器的高抗噪声性能。
