第147章 水运仪象台(2 / 2)

加入书签 | 推荐本书 | 问题反馈 |

枢轮顶部和边上附设一组杠杆装置,相当于钟表中的擒纵器,而擒纵器就解决了机械表最关键的技术难度。

在枢轮东面装有一组两级漏壶,壶水注入水斗,斗满时,枢轮即往下转动,被擒纵器的控制后,使整个仪器便能运转均匀,整个机械轮系的运转依靠水的循环带动仪器转动。

而混象类似天球仪,是一种可绕轴转动的刻画有星宿、赤道、黄道、恒隐圈、恒显圈等的圆球,用于象征天球的运动,与浑仪合称浑天仪,以此来表演天象的变化。

朱高燧将这本书连续翻了四五遍,他一直以为自己的脑袋中装着超越这个时代五百多年的知识,从未想过自己有朝一日会从古人的智慧中求取知识架构。

这水运仪象台不单单是最早的机械表能够用来报时,更是能进行天文观测和天文演示的天文仪器。

书上所记录的尺寸足足有十二米高七米宽,而且绝大部分的部件都是用铜制作,宋朝的苏颂、韩公廉制作成功足足消耗了两万金铜!

朱高燧都不由得赞叹,古人在机械和力学方面其实远远领先于这个时代,这水运仪象台可以当得上是西方机械表的祖先,只不过没有能形成一门真正的学问。

有了从古人这里获取的框架,朱高燧又根据自己所需进行删改。

他所需要的表只需要报时,并且规范每一秒每一分钟的刻度,浑天仪的功能可以直接砍掉。

擒纵器的控制利用水的循环来提供动力的装置也太大,朱高燧把水换成了分量相同的铅块。

耗时半个多月,徐祯又在一边从旁协助,朱高燧终于打造出了第一座机械钟!

他也想做成机械表,但奈何材料和工艺都不允许,能够做成半人高的机械钟已经算是大明的最高技艺了。

朱高燧造出钟,并非是想打造一款单纯的报时机械,而是要将原本模糊的时间观念进行细分。

凭借钟的出现,朱高燧将原本学院时辰计时的方式取消,取而代之的是将一天划分成了二十四个小时,每小时分成六十分钟,每分钟又分成六十秒!

有了完善的时间体系,才能够让物理学中很多概念有更明确的量化标准。

除了钟以外,朱高燧又制作了以汉人标准砝码,规范计量单位。

本想着标准的制作是在大明,那千克、克这样的西方标准单位当然也应该被抛弃,可朱高燧发现若是将千克与克被是公斤、两、钱等单位取代的话,很多物理数据就需要重新计算。

如果朱高燧千克的定义应该出现在三百年后,如今也就堂而皇之的成为了大明发明的计量单位。

统一计量单位,有完整的理论体系,物理学才算是真正的成形!
