Something should be done in 100ms after power up.应该在上电后100ms内（就开始）做某事。 Something should be done for 100ms after power up.上电后某事要做（够）100ms。 Something should be done 100ms after power up.应该在上电后100ms（才开始）做某事。
1。Something should be done in 100ms after power up. 上电后，在100ms内某件事应该做 2。Something should be done for 100ms after power up. 上电后，某件事应该做100ms 3。Something should be done 100ms after power up. 上电后，某件事应该做100ms //省略了介词for
1。Something should be done in 100ms after power up. 某件事在上电以后100ms将做 或：Something should be done within 100ms after power up. 某件事在上电100ms以内将做 2。Something should be done for 100ms after power up. 上电后某件事应该做100ms （指持续时间） 3。Something should be done 100ms after power up. 上电后某件事应该做100ms （指持续时间）
The bulb should be breaked 100ms after power up.// break （过去式 broke） （ 过去分词 broken） 正确的应是： The bulb should be broke 100ms after power up //省掉for 译1：加电后灯泡断开时间达到100ms。//强调延时时间。 译2：加电后灯泡破碎时间达到100ms。//强调爆炸时间。
完全等效于： The bulb should be broke (for)100ms after power up
//-------------------------------------------------- The bulb should be broke in 100ms after power up //不算精准 The bulb should be broke on 100ms after power up //要求定时极精准， 加电100ms后，灯泡会破裂。
A software reset must be included at the beginning of all programs to initialize the control registers after power up.The initialization procedure should be implemented 100ms after power up. 在上电后，所有程序的开头必须包含一个软复位（程序），对控制寄存器进行初始化。初始化程序必须在上电100 ms后执行。
如果是在100 ms之内执行（毫无道理），至少应该在100ms前加一个within。
... should be implemented after power up. 应该在上电后执行 ... should be implemented 100ms after power up. 应该在上电100ms后执行，100ms作after短语的修饰。
类似的说法： Jack is older than Tom. Jack is two years older than Tom.
再者100ms 不是副词不可能修饰“介词短语after power up. ”而且英语的习惯用法（也就是语法书上说的动词动作之后for ***时间段内。之间的for 一般可以省略掉）。
因此按照文法翻译原来意思译文是： A software reset must be included at the beginning of all programs to initialize the control registers after power up.The initialization procedure should be implemented (for)100ms after power up. //这句子内省掉了(for). 在上电之后的任何编程操作之前，必须先执行一次软复位操作，以初始化控制寄存器。(芯片内部)初始化寄存器的过程需要花费100ms的时间.//compter00 大虾的译文。
