首先是一些数学信息：Newton's Law of Cooling tells us that the temperature,T,of a cooling object drops at a rate that is proportional to the difference between the temperature of the object and the temperature,C,of the surrounding medium.So,dT/dt = k(T - C)Solving this equation (finding the original function),we getT(t) = ae^kt + Cwhere a is a constant that needs to be determined.1.接下来就是题目了：星期二早晨9点前,你是一个验尸官,你接到一个任务去调查一个男人的死亡.你被领到尸体前,然后在九点钟时,你量了尸体的温度是67.41度.你还知道这

首先是一些数学信息：
Newton's Law of Cooling tells us that the temperature,T,of a cooling object drops at a rate that is proportional to the difference between the temperature of the object and the temperature,C,of the surrounding medium.So,
dT/dt = k(T - C)
Solving this equation (finding the original function),we get
T(t) = ae^kt + C
where a is a constant that needs to be determined.
1.接下来就是题目了：
星期二早晨9点前,你是一个验尸官,你接到一个任务去调查一个男人的死亡.你被领到尸体前,然后在九点钟时,你量了尸体的温度是67.41度.你还知道这个屋子的室温是60度.你在一个小时后,再次测量了尸体的温度.现在尸体温度是67.05度.设定这个尸体一直在这个房间,且房间的温度不变是60度,这个男人什么时候死的?
2.
你发现了这个男人有骨癌而且正在使用锶-90,你发现,该名男子在上午十点失去了他最后一次剂量的锶- 90的2.37%.The half-life of 锶-90 是 28.9 天.请问该男子何时注射了他最后一次剂量的锶-90?
3.结论
这起案件发生了什么?是自杀还是谋杀?还是其他?
感激不尽!
