    其实几个月下来，他俩接触虽然不少。但正所谓老大和老二较劲，却把老三打没了。因为李明月和江雪迎互相暗战，互相提防，结果小竹子却没了可乘之机。

    “嗯嗯。”牛长老虽不敢言，却十分心动，但航海者的谨慎，让他不敢轻信任何东西。

    这套装置是欧洲水手，在大明的‘木板测速法’基础上，改进出来的‘沙漏计速法’。他们利用等距打结的绳索计程，用一个14或者28秒的沙漏计时。这样观测每14或28秒内放出的节数，就可以表示出船舶的速度了。

    至今船舶航速单位依然称为‘节’……不过一节等于1852米左右只是个人为规定，所以赵公子从统一度量衡的角度，将一节规定为一千米。

    同时，为了取整，他将计时单位也改为18秒。这样，两个绳结间的距离，也就从反人类的英制23英尺7.5英寸，变成了清清爽爽的5米。

    并且赵昊将沙漏改进为发条计时器。只要将圆形计时器的盖子拧到头，里头就会发出哒哒的发条声，盖子往回转动。18秒后铛的一声，计时结束，转动停止。
