This paper uses an agricultural trade policy simulation model to quantitatively evaluate the effects of Blue Box policy reform on agricultural production and trade, and further provides specific proposals regarding China ＇ s reform position. The results indicate that, if the reform could achieve a reduction in distorting supports in more developed countries, China＇ s total agricultural production would increase, accompanied by a decrease in agricultural imports and a slight increase in exports. In terms of social welfare, producers would gain significantly, consumers would lose and government would not suffer greatly, which is in accordance with current agricultural policies in China. As a core member of G20, China should approve a subsidy level as low as possible required by Blue Box to achieve ＂substantial reductions in trade-distorting domestic supports＂.

After inserting IVD into bilateralvas, allrats (9) becam e sterilized as proved by m atetestand thefactthatno sperm w asfound in fem alevagina afterm at- ing. Half a year later, there had been a large am ountof sperm in vaslum en dilated and sperm granulom a w asfound in theproxim alend of IVD.

A few sperm s w ith de- form ed structurew erefound in thedistalend of IVD. Conclusion: our studiesshow ed that IVD could be an effective device in SD rats. Fluid and som e deform ed sperm s m ay pass through IVD, but these sperm s have no fertility. The m echanism of IVD needsto be further investigated.

Traumatic spinal cord injury(SCI)is a devastating exogenous injury with long-lasting consequences and a leading cause of death and disability *** in assistive technology,rehabilitative interventions,and the ability to identify and intervene in secondary conditions have significantly increased the long-term survival rate of SCI patients,with some people even living well into their seventh or eighth *** survival changes have led neurotrauma researchers to examine how SCI interacts with brain *** health and epidemiological data showed that patients with long-term SCI can have a lower life expectancy and quality of life,along with a higher risk of comorbidities and complications.

we design a novel surface-electrode ion trap based on the micro-structure Paul trap model, which can realize transport with low heating rate and expand quantum qubits in the radial direction, and the most important it can overcome the difficulties of cooling ions on the surface chip and the design of symmetrical radiofrequency electrodes make the DC control more convenient. we also discuss the design and optimization of junctions between high performable five-line trap and radiofrequency ion-trap arrays that enable realize multiple cooled ions and expand quantum qubit on chip device. A detailed description of a multi-objective optimization procedure applicable to an arbitrary planar junction is presented. Such studies are important to high dimension to cool ions and achieve scaling in trapped-ion quantum information processor.
