Based on a nonlinear fractional complex transformation, a certain fractional partial differential equation can be turned into another ordinary differential equation of integer order. For illustrating the validity of this method, we apply it to the space-time fractional generalized Hirota-Satsuma coupled KdV equations and the time-fractional fifth-order Sawada-Kotera equation. As a result, some new exact solutions for them are successfully established.展开更多

The amounts or DNA in chondrocytesand glucuronate in matrix were measured. And the chondrocytes were observed by inversion microscope and transmission electron microscope (TEM). The results showed that the cultured chondrocytes were damaged by all the six mycotoxinsl and the synthesis of DNA and the divided reproductionof chondrocytes were restrained; the damage errect was more evident, esl,ecially in the early stage ofculturel the higher concentration or toxin in the media was used, the lower density of the culturalckondrocytes was observed; the cells were even round damaged and dead, so long as the media contolued toxin.
