time-base怎么记

This paper presents a new precise evaluation method for time base and trigger characteristics of digital storage oscilloscope. By using sine wave curve-fit method, the time-base, the slope of trigger, trigger level, trigger delay, and the trigger jitter have been evaluated accurately.

本文提出了一种数字存储示波器时基和触发特性的精确评价方法，通过使用正弦波拟合法，其时基准确度、触发沿斜率、触发电平不确定度、触发延时误差以及触发沿晃动被精确评价；

When we extend this regression model to time-base, according to the theory of trapeziform integral, we calculate monthly total of the gross solar radiant energy by calculating the average daily total of the gross solar radiant energy in a month.

在对回归模型进行时间推广的过程中，根据梯形积分的思想，提出了通过计算总辐射月平均日总量求得总辐射月总量的方法。
