前值，计算(i,j) 下一时刻的值需要用到它的八邻点，反推他的八邻点下一时刻的值也
需要用到(i,j)当前值。 所以 map的输出就是 (i-1, j) -> (i,j)当前值，(i+1,j) ->

the magnetic field is there to direct electrons emitted by P to S.
How about this minor modification: coat P with a material that emits
electrons at a lower temprature (like those used in a vaccum tube), and
put both P and S on that heat source, but insulate P slightly so it has a
lower temprature (but still emits electrons).
In this setup, the electrons still come out of P, get collected at S. Yet
S is hotter (at a higher temprature) than P.
