A low power mixer and a basedband variable gain amplifier are designed for frequency downconversion and gain-adjustment, respectively. 最后实现了一个低功率的混频器及基频可变增益放大器，且此放大器可线性调整增益。
The experimental results indicated that the red laser of low power has remarkable stimulation on the preliferate of regetative cells in H. pluvialis. 实验结果表明，低功率的红色激光对红球藻营养细胞的增殖具有明显的促进作用。
