Though comparing Canny operator and center B spline dyadic wavelet, the following conclusion is proven in this dissertation: a Center B spline function has tight support and Canny operator hasn't. b Center B spline function asymptotic convergence to Gaussian function and the derivative of Center B spline function asymptotic convergence to Canny operator. c The derivative of fourth order center spline B function is more suitable as a optimal edge detector than Canny operator. d Center B spline function can balance the smoothing and approximation of original data, and the fourth center B spline function is the only optimal solution of two order smoothing problem. e The error between the valve of time-frequency uncertainty of the fourth center B spline function and the lower bound of time-frequency uncertainty does not exceed 0.143% of the lower bound. f The derivative of center spline B function can construct a stability dyadic wavelet and can give a fast algorithm for multiscale edge detection, but Canny operator can do neither.

作者给出了Canny算子与中心B样条二进小波严格的比较证明，得出如下结论：a中心B样条函数具有紧支集，Canny算子不具有紧支集。b中心B样条函数的极限收敛于高斯函数，中心B样条函数的导数收敛于Canny算子。c四阶中心B样条函数的导数比Canny算子更接近最佳边缘检测滤波器。d中心B样条函数比高斯函数更能兼顾对原函数平滑和逼近的折中要求，并且四阶中心B样条函数是二阶逼近问题的唯一最优解。e四阶中心B样条函数的时频测不准关系值与时频测不准关系下界的逼近误差不超过0.143％。f中心B样条函数的导数可以构成稳定的二进小波，存在快速的多尺度算法；而Canny算子不构成稳定的二进小波，无法给出快速的多尺度算法。

Firstly, aromatic carbanions were prepared by 1 Br/Li exchange of bromo dithieno[2,3-b:3',2'-d]thiophene with n-BuLi in THF at low temperature; 2 deprotonation of dithieno[2,3-b:3',2'-d]thiophene with LDA.

And more, ERK contents between group A and B, group C and D were not dramatically different. The pathological lesions indicated that intestinal tissue necrosis was severe in group C and D, which were graded 3 points, but obviously lessened in group A and B, which was graded 1 point, with ITF interfering. Conclusion: Intestinal inflammation was ameliorated after ITF was injected hypodermically or intraperitoneally.

Methods 20 rats were randomly divided into A, B, C, D and E group. The models of cerebral anoxia in group A and C were made by hypopiesia and hypoxia, and the models of hypoxia-reoxgenation were made in group B and D. 24h and 1h before establishment of models, ginsenoside Rb3 was injected peritoneally in rats of group C and D, respectively. The number and form of GABA-like immunoreactive neurons in hippocampus CA1 area of rats after brain hypoxia-reoxgenation were investigated with immunohistochemistry.

It is confirmed that under the illumination of light the dark-adaptedBR is quickly turned into the light-adapted, and undergoes a photo-chemical cycle then through a sequence of intermediates of J, K, L,comes into a more stable intermediate-M state. M state relaxes to B state in about one hour. B state converts completely into D state after 24 hours. B state initiates the photochemical cycle under illumination, while it can transform into D state in the dark. So B state is a key intermediate in the BR photochemical cycle.

实验证实，样品受光照激发后很快从暗适应型经过光适应型进入光循环，经过一系列的光化学中间体到达较稳定的M态。M态经过约1小时热驰豫完全回到光适应型B态，B态再经过24小时缓慢热驰豫完全回到暗适应型D态。B态受光则进入光循环，不受光则转化为D态，从而认为B态是菌紫质光循环路径中一个重要的分支节点。

The 4th left rib was cut and a model of left coronary artery occlusion/release was carried outo Rats were divided randomly into 4 groups: control group without LCA occlusion (group A, n=6);I/R group(group B, n=6); ketamine(5mg.kg-1)+I/R group (group C, n=6); ketamine(10mg.kg-1)+I/R group(group D,n=6)o All rats in groups B, C , D were subjected to 30 minutes of LCA occlusion followed by 120minutes of reperfusion. Rats in group C and D were injected with 5mg.kg-1 and 10mg.kg-1 of ketamine before reperfusion, respectively. Significant electrocardiogram and color changes at the area at risk were considered indicative of successful coronary occlusion and reperfusionc Serum was exampled from left jugular vein at 30 minutes and 120 minutes during reperfusion to measure IL-6 and TNF- level by ELISA measurements. After reperfusion of 120 minutes, the heart was removed and the cardiac apex was exampled with snap-frozen in liquid nitrogen and stored at -70 C .
