【MEMS传感器：TDK推出扩大感应范围的基于MEMS的新型“硅芯片声纳”超声波飞行时间传感器】TDK 公司（TSE：6762）宣布现在可以选择扩大了感应范围的基于Chirp CH-201 MEMS的超声波飞行时间（ToF）传感器的原始设备制造商（OEM）。此款ToF传感器利用微型超声换能器芯片发射超声波脉冲，然后收听从位于传感器视场中的目标返回的回波。通过基于超声波飞行时间（ToF）计算的距离，传感器可以确定某一物体相对于器件的位置，同时触发编程行为。https://t.cn/A6hPjSPQ
阴冷的天夹杂着小雨，没有了前几日阳光的温暖，一切显得格外安静。没有人，只有房屋，树木和车。甚至能清晰的听到高高低低的鸟叫声，隐隐约约远处时不时的火车汽笛声。临近正午，穿过屋顶的天空如此苍白。
It’s a chilly day with drizzle,everything is very quiet.I could see no men,only houses,trees,and cars. I could even hear birds chirp faster and louder, the siren miles away occasionally.It is nearly noon.The sky is pale over the roofs.

《送梓州李使君》
王维 唐代
万壑树参天，千山响杜鹃。
山中一夜雨，树杪百重泉。
汉女输橦布，巴人讼芋田。
文翁翻教授，不敢倚先贤。

Thousands of valleys're full of towering trees ;
Where cuckoos chirp in so many a hill.
Overnight fell a heavy rain like these;
Twig tips seam to have so many a rill.
With tree-flower cloth Women there pay tax,
And case of taro fields‘s oft brought to law.
WEN Weng's instruction we can never lax;
We dare not live up to wise man of yore.
