According to different reducing agents and their concentrations, the particle size produced varies between approximately 1 and 100 nm-the larger the size, the higher the signaling efficiency.
根据不同的还原试剂和试剂浓度，产生的颗粒大小在大约1nm和100nm之间变化，尺寸越大，信号效果越高。
One NM is one-1 billionth meter.
一纳米是十亿分之一米。
Laser is the key component in multichannel optical fiber CATV system for improvement of the signal quality, especially in 1 550 nm VSB-AM system based on the g.
