We are still looking at the quality (duty cycle and stationarity) of the first few months of S5 data, and trying to decide if we want to do a longer search this time.

这都不是问题，我们关注的是S5头几个月的数据质量（协同工作周期和稳定性），并以此决定这一次是否要进行更长久的寻找。

We used a Mega Hz focused transducer to focus on the surface of the calculus model and tried different frequency, intensity, time and duty cycle.

本文利用兆赫兹频率级别的聚焦超声换能器诱发冲击波作用于结石模型材料，采用不同的声波参数包括频率、强度、占空比等进行了实验。

The time of high level and the cycle for input pulse was measured with micro-controller to calculate duty cycles.

单片机通过测量输入脉冲的高电平时间及周期而实现占空比测量。
