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。

Material and MethodsRA Rabbit Model group: 15 early RA rabbits of the same weight and variety Control group:10 normal rabbits of the same weight and varietyMethods of making RA rabbit model:elect 15 normal rabbits of the same weight and variety, dissolve Ovalbumin in 0.9% sodium chloride solution, to make the solution of 20mg/ml concengtration, blend the same quantity of complete Freund′s Adjuvant equably ,inject the mixed solution into endermic tissue of the rabbit′s scapular section, making the rabbits allergic, inject 1 ml of the mixed solution to one rabbit every time, inject 1 ml of the mixed solution in 5 different places of the rabbit′s scapular section, inject the rabbit one time every week,inject 3 weeks continuously,it turned out to be that the rabbits will be allergic, inject Ovalbumin blent with the 0.9% sodium chloride solution into the knee joint cavity of the rabbits in the fourth week, 5 mg Ovalbumin every knee joint cavity,two knees of every rabbit of the 15 rabbits are both injected,the arthrosis diameter and the exterior temperature of the knees will be added obviously in 24 hours,and they will drop gradually,at the time of the 14th or 21th day, the arthrosis diameter and the exterior temperature of the knees will get to the balance time,the incidence rate of RA is 100%.after the RA model succeeds,it is the early time of RA from the first week to the fourth week,after the fourth week,it is the late time of RA, the cartilage of the femoral condyle and the subchondral bone cortices will be changed unrecoverily.
资料与方法RA模型组:早期RA家兔模型15只,品种及体重接近。对照组:正常家兔10只,品种及体重接近。RA家兔模型制作方法:选取15只成年家兔,体重、品种接近,将卵蛋白溶解于生理盐水,配成浓度为20mg/ml的溶液,与等量完全弗氏佐剂混匀,注入家兔肩胛区皮下致敏,每只家兔每次注射1ml,于肩胛区5个不同区域注射,每周一次,连续注射3周而致敏,第4周向膝关节腔注射卵蛋白生理盐水溶液,每只关节腔注射5mg卵蛋白,15只家兔膝关节全部注射,24h内此关节直径和表面温度大幅度上升,以后缓慢下降,至14~21d达到平台期,发病率达100%。造模成功后第1~4周为早期改变,第4周以后出现不可逆的关节软骨及骨破坏。采用高频超声对RA模型组与对照组的膝关节髌上囊液体厚度、滑膜及股骨髁软骨厚度及软骨下骨皮质的回声情况进行对比观察。结果RA组模型组膝关节髌上囊积液及滑膜的厚度明显厚于对照组,其股骨髁软骨的厚度与对照组相比无明显差异,其软骨下骨皮质与对照组相比无明显改变。

They share many similar or the same featutes with Archaeopteryx or other primitive birds, such as: U-shaped furcula, uncinate process, laterally facing glenoid of shoulder girdle, comparatively long forelimb, large semilunate carple, retroverted pubis, ascending process of astragalus, and "modern feathers"with rachis and barbs etc.

In the normal rats (n=5、6), CGRP-LI were mainly present in small and some medium-sized neurons and the primary afferent fibers and ter- minals in laminae Ⅰ,Ⅱ,Ⅴ,Ⅹ and Lissauer's tract of the spinal cord; GAL- and SP-LI were mainly present in small neurons and the superficial layers of the dorsal horn. After the adjuvant injection both CGRP-and SP-LI were in- creased corresponding to the development of arthritis. On day 2, CGRP-and SP-LI were moderately increased in laminae Ⅰ,Ⅱ and the posterior commis- sure of the spinal cord and small neurons in DRG, while SP was obviously in- creased in the superficial layers and DRG. On day 14, CGRP-LI were marked- ly enhanced in the above regions with the development of polyarthritis. Some- times many strongly stained long fibers could be seen in the posteriot commis- sure.
在DRG中,CGRP主要分布于小和中等神经元之中,SP和GAL主要分布于小神经元之中;2、注入弗氏完全佐剂(含冻干结核菌0.5mg)后第2天动物(各5~6例)产生具有明显红、肿、热、痛和痛敏的急性关节炎,免疫组化实验观察到注射侧脊髓背角和DRG中CGRP-和SP-LI明显增加;在佐剂后第14天,动物患肢肿胀、痛敏和自发痛均进一步加重,部分动物健肢也出现红肿,产生多发性关节炎时,脊髓背角浅层和DRG中CGRP-和SP-LI增加更为明显,并且在灰质后联合中可见许多深染的CGRP-LI长纤维;在佐剂后第21和28天,随着佐剂性关节炎的逐渐恢复,脊髓背角和DRG中CGRP-和SP-LI也接近正常。
