1.Despite their drawbacks, sundials continued to be used for many years after the invention of mechanical clocks.
尽管日晷存在一定的缺点，但是在机械钟表出现之前，日晷一直是最常用的计时工具。
2.Inventors created sundials, which indicate time by the length or direction of the sun's shadow, to track temporal hours during the day.
当时的发明家制造了日晷，利用太阳阴影的长度或角度，来测量白天真时的变化。
3.The developement of mechanical timepieces spurred the research for more accurate sundials with which to regular them.
机械计时器发展的刺激了对更精确日晷的研究，以便用来校正他们（机械计时器）。
4.timepieces spurred the search for more accurate sundials with which to regulate them.
机械计时器的发展促使人们寻求更精确。
5.To be accurate, beyond needing a sunny day, sundials must be corrected based on latitude and time of year.
除了必须要有阳光外，一台精准的日晷还需要根据纬度和季节来作校准。
6.The development of mechanical timepieces spurred the search for abundance accurate sundials with which to regulate them.
机械计时器的进展促使大部分人寻求更精确的日晷，以便校准机械计时器。
7.The development of mechanical timepieces spurred the search for more accurate . sundials with which to regulate them.
机械计时器的发展促使人们寻求更精确的日晷，以便校准机械计时器。
8.The development of mechanical timepieces purred the research for more accurate sundials with which to regulate them.
计时设备的发展，促进了通过调整这些仪器来寻找更为精确的测量日晷的方法。
9.Lord, it is time. The summer was very big. Lay thy shadow on the sundials, and on the meadows let the winds go loose.
神啊，是时候了。夏日已满涨。请把你的身影显在日晷上，牧野连绵，引得风也欢畅。
