杳杳寒山道，落落冷涧滨。
啾啾常有鸟，寂寂更无人。
淅淅风吹面，纷纷雪积身。
朝朝不见日，岁岁不知春。
Long long the pathway to Cold Hill;
Drear, drear the waterside so chill.
Chirp, chirp, I often hear the bird;
Gust by gust winds caress my face;
Flake on flake snow covers all trace.
From day to day the sun won’t swing;
From year to year I know spring.

【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.
