Firstly, the definitions of complex quasi-random variable and primary norm are introduced.

引入复拟(概率)随机变量，准范数的定义。

Then based on it, we give an estimation on the difference between this local entropy solution and the solution of the quasi-one-dimensional problem in L2 norm.

然后在此基础上，我们讨论了上述熵解同拟一维流问题的解在L2意义下的相近程度。
