(Toufigh,2002) قام بدراسة مسائل الجريان حيث قام بفرض بان معاملات النفاذية ثابتة في معادلة لابلاس مع الفراغ والزمن و لكن بالواقع الحقلي تكون تلك القيم متغيرة.

النتائج (الإنجليزية) 1:

(Toufigh, 2002) studied the runoff where he imposed that the constant permeability coefficients in the Laplace equation with the space and time issues, but the reality field are those variable values.

(Toufigh,2002) studied the issues of flux, where he assumed that permeability coefficients were constant in the LaPlace equation with space and time, but in reality, those values were variable.

Toufigh and 2002, where the permeability coefficient is fixed in the Laplace equation of vacuum and time, but in fact, these values are variable.
