Conversion from extracapsular cataract surgery to small-incision phacoemulsification is inevitably associated with a learning curve. Retrospective analysis of one surgeon's learning curve was carried out on the first 50 consecutive operations using small-incision phacoemulsification. Parameters were evaluated,...
Here, simultaneous 50Gbps four channel wavelength conversion is established in S and C bands of ITU grid using four wave mixing (FWM) technique in high nonlinear fiber (HNLF) without additional pump signals. Since the four channel wavelength conversion is to be performed, the frequency spacing ...

一、double最大有效位数16位，50的阶乘老长了，C中数值类变量都不可能运算、表示出来，只能采用大数相乘的方法，自己写运算程序去实现了。二、你的程序太乱了 给你一个可运行的程序，但结果并不是准确的 include <stdio.h> int main(){ double fac(int n);int n;double y;printf("input an ...
Furthermore, modulation and frequency conversion are made through digital signal processing, the D/A converter directly outputs the transmit frequency, achieving the purest transmission C/N. By using 450 W FETs device in 200 W output, the PA achieves excellent IMD characteristics. * 200 W and 1...
