It was shown that the conventional water treatment(seasonal irrigated amount: 175 mm) reduced spinach growth comparedto the water balance treatments (seasonal irrigated amount: 80 and 85mm) at he same N supply level due to N loss through leaching causedby excessive water supply.展开更多
In this paper,by using the G_(m,1)~(1,1)-system,we study Darboux transformations for space-like isothermic surfaces in Minkowski space R~(m,1),where G_(m,1)~(1,1)=O(m+1,2)/O(m,1)×O(1,1).

In fact, it is a membrane wave function in CP3 space. In this article, we use non-Abelian Berry phase to anaJyze the statistics of this membrane wave function. Our results show that the membrane wave function obeys fractional statistics. It is the rare example to realize fractional statistics in higher-dimensiona space than 2D. And, it will help to make clear the unresolved problems in 4D quantum Hall effect.展开更多
