了 一直有关注他，看了三个月总结下来就是：
不管库存如何 我跌
不管石油是涨是跌 我继续跌
不管是晴天还是暴雪 我还是跌
不管供需关系不管政策 我就是要跌
总之 没有最低只有更低，没有底部没有节操
珍爱绳命 远离UGAZ |

天然气下行空间已经不大，耐性再等等，等底过去了再操 |

发帖数: 48 | 10 很早以前写过这种程序，基本思路：
1. tty设置为非缓冲模式(raw)，大概的code如下，详细参看APUE (advanced
programming in unix environment)
2. 用ansi/vt100控制码控制光标。参看http://www.termsys.demon.co.uk/vtansi.htm
另外，使用cursor库可能更方便。不过我没用过。
void tty_raw(int fd) {
struct termios new_tty;
tcgetattr(fd, &save_tty);
new_tty = save_tty;
new_tty.c_lflag &= ~(ECHO | ICANON | IEXTEN | ISIG);
new_tty.c_iflag &= ~(BRKINT | ICRNL | INPCK | ISTRIP | IXON);
new_tty.c_cflag &= ~(CSIZE | PARENB);
new_tty.c_cflag |= CS8;
new_tty.c_cc[VMIN] = |

发帖数: 555 | 11 Assuming the poles of the OpAmp and 1/(Cload*Rd) are located at high
frequency, then 3db bandwidth of the circuit you are showing is determined
by R and C of the node vx.
if you ignore cp, (assume cp is 0), the output resistance looking into vx is
1/((1+A)*gm). Capacitance load is C2. pole = 1/RC=(1+A)gm/C2
Note: if we ignore Cp, the equivalent load capacitance to Vx is C2 only. The
reason is simple. if you apply at test current source at vx, the current
won't go to C1, because it is assumed ... 阅读全帖 |
