Results show that the heavy rainfall event occurred under the favorable environmental conditions, resulted from the interaction of mid-and low-latitude systems. The mesoscale convergence and the mesoscale low triggered the occurrence of the heavy rainfall. Rain clusters bringing the heavy rainfall were related to meso-β systems. The meso-β mesoscale rain clusters appeared to the north of the cyclone center on 1000 hPa after filtering and to the south of the meso-α convergence line on 850 hPa.

The results showed that five bands including POD-1, POD-2, POD-3, POD-4 and POD-5 were detected in the gel of POD as well as EST-1, EST-2, EST-3, EST4 and EST-5 for EST. POD-3 and POD-4 were common in all the tissues, but most intensive in F. tartaricum. POD-2 was only discovered in the leaves of F. cymosum and caudex of F. cymosum 1. Although there was some difference between the location, POD-2 appeared in the caudexes of three buckwheat and root of F. tartaricum. POD-5 was detected in all leaves and caudx of F.

In conclusion, our studies indicated that, by reducing the concentration of corticoid, increasing the GH concentration, dietary glutamine could maintain the N balance in the body, induce the intestinal glutamine extraction from blood, maintain the glutamine store in muscle tissue and plasma, decrease the glutamine flux from muscle tissue and protein catabolism. As the key fuel of intestinal mucosa and lymphocytes, exogenous glutamine maintained the intestinal structure, function and the CD4〓/CD8〓 ratio. In addition, glutamine normalized the SIgA containing cells'quantity and distribution through stimulating the IL-6 gene expression.

The results showed that, NO-3-N contents and nitrate reductase activity had obvious diversity in different spinach varieties and different organs of the same plant. The NO-3-N contents in stem were the highest, followed by petioles, then mesophylls, and were the lowest in roots. When the ratio of root to shoot was higher, the NO-3-N contents in plants were lower. NR activity was higher in root especially in lateral root. The NO-3-N contents in mesophyll and petiole were negative correlated with the in vitro -NR activity and in vivo -NR activity in roots.

Equidistance point and difference theory in theory of function approximation are studied. Meanwhile, the relation among difference, difference quotient and derivate is revealed. By drawing Lagrange's and Cauchy's theorem of mean on difference and Taylor's formula into difference function, four theorems, such as Lagrange's theorem of mean on difference, are concluded in simple way. On the basis of these conclusions, the asymptotic property of middle point is studied, a series of new conclusions are drawn and the discussions on the asymptotic property of middle point in differential mid-value are summarized.

The five prosthetic groups (FAD, [2Fe-2S], [4Fe-4S], [3Fe-4S] and heme group) required for electron transfer from succinate to ubiquinone were unambiguously assigned into the electron density map. Besides, we find there are some electron densities around the Qp pocket at the matrix side and we believe it represents the head structure of ubiquinone, which is proved by the inhibitor bound structure that 2-TTFA just locating at the Qp site. At the same time, we find there is the second 2-TTFA binding site, locating the inter-membrane side. This finding will change our knowledge about the electron transfer inside Complex II and the ubiquinone transfer between Complex II and Complex III, and endow a new role of Complex II in electron transfer chain.
