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.

Laboratory experiments were carried out to study the survival and development of the Harmonia axyridis feeding on Chaito phorus popleti on high insect-resisitance hybrid poplar 741(Pb29) and medium insect-resisitance hybrid poplar 741(Pbl7).The API 741 poplar was used as control.The mortality and development during immature period,adult,baby mass.eclosion and sex ratio of H. axyridis were measured.The results showed that:to contrast The API 741, Chaito phorus popleti on Pbl7 and Pb29 has no significantly impacts on eclosion,pupation, ecdysis,mortality of immature period and pupa stage;Although every development stage of ladybeetles were not affected to ,the pupal duration of ladybeetles was lowered than the control;The body mass,eclosion and sex ratio have no significant difference.

将定子一种极数的磁场感应于转子绕组中的电流,通过集电环和电刷,但由另一种极数的磁场感应的电流,却自动流经另一闭合回路,而不通过集电环和电刷:于是,如果后一种极数是电动机的工作基波磁场,而把前一种极数作为用以起动的谐波磁场,则可以把起动电阻直接焊接在转子绕组上,而把集电环和电刷取消,从而出现了转子电路上无集电环、无电刷、无触点的谐波起动绕线型感应电动机。

objective to investigate the existence of the erythropoiesis inhibitors.methods the present study included twelve undialyzed esrd patients with anemia.the sera from the uremic patients were added to cfu-e and bfu-e culture in the concentrations ranging from 1.25% to 5%.in vitro cfu-e and bfu-e growth in the presence of sera from esrd patients was compared with in the presence normal human subjects with the use of normal mice bone marrows.results the effects of the sera from uremic patients on cfu-e and bfu-e colony growth in concentrations ranging from 1.25% to 5% were investigated to be dose-dependent.the effect increased with the concentrations increasing of the sera(p<0.05).there were not significant inhibitory effect on the cfu-e and bfu-e growth of mice bone marrow in vitro from sera of the normal subjects.conclusion the erythropoiesis inhibitors exist in uremic sera which has a dose-dependent inhibitive effects on the growth cfu-e and bfu-e of normal mice bone marrow cells.
选择12例尿毒症肾性贫血未透析患者为试验组,另选正常健康体检者12例为正常对照组,将实验组、正常对照组血清分别稀释成不同终浓度,采用甲基纤维素细胞培养的方法对小鼠骨髓细胞进行培养,对比不同浓度血清组红系集落形成单位、红系爆式形成单位的集落数。结果在实验组中,与血清浓度为0的浓度组相比,与各浓度组血清共同培养的小鼠骨髓cfu-e和bfu-e的集落数均明显减少,且随血清浓度的增加,小鼠骨髓cfu-e和bfu-e的集落数逐渐减少,各浓度组间差异有显著性(p<0.05)。结论尿毒症患者血清抑制小鼠骨髓红系祖细胞集落形成,随患者血清浓度的增加,抑制作用增强,具有剂量依赖性。
