查询词典 tight

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。

So one man is described as generous, another as a miser; one is called open-handed, another tight-fisted; one man is cruel, another gentle; one untrustworthy, another reliable; one effeminate and cowardly, another bold and violent; one sympathetic, another self-important; one promiscuous, another monogamous; one straightforward, another duplicitous; one tough, another easy-going; one serious, another cheerful; one religious, another atheistical; and so on.

因而，说此人慷慨大方，彼人是吝啬鬼；此人出手大方，彼人一毛不拔；此人冷酷无情，彼人和蔼可亲；此人不可信赖，彼人忠诚可靠；此人柔弱胆怯，彼人勇猛凶悍；此人同情他人，彼人惟我独尊；此人荒淫无度，彼人洁身自爱；此人刚正不阿，彼人心地奸诈；此人固执己见，彼人一团和气；此人不苟言笑，彼人开朗乐观；此人虔信宗教，彼人心无上帝；如此等等。

Objective It was reported that rALR (rat augmenter of liver regeneration) distribute in most of tissue and organ of rat, no-tissue specility; mRNA expression of rALR was identified variedly in different tissue, strongest in testis. But nowadays there was not some study on ALR in rat testis. Here to confirm the expression and localization of ALR in infancy,adult and old rat testis,comparing the change of ALR expression degree before per 70 PH and after per 70 PH. In order to evaluate expression principle of ALR in rat testis and know if ALR has tight connection with spermatogenesis and development of testis, to explore the relation between ALR and reproduction, to discover the possible expression character and functional methods of ALR.

目的：文献报道rALR分布于各组织器官，无组织特异性，但其mRNA在各组织的表达强度有差异，在睾丸组织表达最强，目前对大鼠睾丸ALR表达尚无深入的研究；本实验研究不同年龄段大鼠睾丸组织中肝再生增强因子的表达水平、表达部位、以及表达的方式，进而探讨睾丸ALR与睾丸发育、精子生成以及生殖活动的关系；同时探究睾丸组织ALR表达是否参与了肝脏的再生过程中，进一步了解睾丸ALR表达的特性及作用方式。
