Now, users could write shell scripts; store and export information in variables; control file descriptors; control signal handling, for loops, and case statements; and so much more.
到这时，用户可以编写shell脚本，在变量中存储信息和导出信息，控制文件描述符，控制信号处理，使用for循环和case语句，以及其他大量功能。
See the section on Advanced Event and Signal Handling for more details on this propagation process.

The benefits of large effective area fibers are higher power handling capability for improved system signal to noise ratio (SNR), and longer amplifier spacing.
由于大有效面积非零色散位移光纤具有较高的额定最大功率，其直接效益之一就是可改善系统信噪比和加大放大器间隔。
