  偏微分符号(不好意思,打不出来) 有人把它读partial 或者d
  但这样读都不正规,最正规读法为round
  因为这个符号是法国人发明的,一开始就叫round
  
  倒三角符号(不好意思,打不出来2) 读作nabla或者del
  读nabla的居多,后者在某些英文书里会见到。
  
  nabla符号本身具有不同的功能,当它按不同的乘法规则作用于函数时会分别得到
  梯度:grandient 符号为grad
  散度:divergence 符号为div
  此时可直接读作grandient(divergence) of ...
  
  
  二、一些函数关系的读法
  
  A与B的乘积 the ___ product of A and B
  (___中填乘积的性质,例如外积就填outer,内积就填inner)
  
  A乘以B A times B or A is multiplied by B
  
  A/B A over B B分之A的最普通读法
  f(x) f of x 函数f(x)
  exp(n) e to powers of n e的n次幂
  
  
  三、应用举例
  
  示例:
  
  上面的薛定谔方程读作
  i h bar round ψ over round t is equal to minius h bar square nabla square ψ over two μ plus U times ψ
  
  注:这只是按方程的形式顺读,要从语句的逻辑关系判别方程的形式比较难。老外遇到后者一般就直接写式子了:)
