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。

In order to study the intake air flow characteristics in four-valve diesel engines, in this dissertation hot-wire anemometer and PIV twodimension instantaneous measuring technique are used. Extensive experimental study on two intake valve exit flow fields and longitudinal section flow field in cylinder are performed for different type of diesel engines. Great researching progress have been made on the interaction between two intake ports, and the formation process of in-cylinder swirl and flow field structure of cross and longitudinal section for four valve diesel engines. These results are presented in China for the first time and without such kind of research work reported abroad as detailed and deepgoing as this dissertation. The author designs and makes a set of hot wire measuring velocity device to measure the velocity distribution around the intake valve annulus and the cross section flow field in cylinder.

Through difference significance tests and analyses, it finds that (1) man students more possibly form identity achievement, and woman students more possibly form identity foreclosure and identity diffusion; and (2) the difference of self-identity status between man and woman students is associated with various domains; and (3) self-identity status between man and woman students have some similarities that identity exploration has the same importance to both; and (4) grade-one is a period when students face up to more identity crises, and grade-two is key period of identity formation, and grade-three is a developmental period of identity that provides the basis for re-solution of the emergence of new identity crises in grade-four;(5) there is a gradually enhanced direction from lower self-identity statuses to advanced ones from grade-one to grade-three, but there is also a direction that reentry into the identity crisis by grade-four. It indicates that the identity achievement formation does not mean the end of development of self-identity and proves that there is a continuous MAMA cycle in self-identity development; and (6) that students self-identity status mainly is identity moratorium provides some evidence for which there is a Moratorium in student development, and which self-identity formation is not easy; and (7) the development of student self-identity is associated with various domains, what students pay most attention to firstly is vocation, secondly life philosophy, and lower interesting in political and religious domains in ideology; for relational domains, students pay more attention to dating and friendship compared to sex role and recreation domain.
通过差异显著性检验和分析发现:(1)男生更可能形成成就型同一性,女生则更可能形成排他型和弥散型同一性;(2)男女大学生自我同一性的差异与不同的领域相关;(3)男女大学生自我同一性也存在相似性,同一性探索对于男女大学生同样重要;(4)大学一年级是同一性危机面对较多的时期,二年级为同一性形成的关键期,三年级为同一性的发展期,所形成的同一性为四年级所出现新的同一性危机的解决提供了基础;(5)从一年级到三年级存在从低级的自我同一性向高级的自我同一型转变的渐进增强,但到四年级又有重新进入同一性危机的趋势,说明大学生成就型自我同一性的形成并不意味着自我同一性发展的结束,证明了自我同一性发展的MAMA周期持续存在的特点;(6)学生自我同一性状态主要还处于延缓型同一性状态,进一步证明大学生发展心理合法延缓期的存在,以及自我同一性形成不是一件很容易的事情;(7)大学生自我同一性的发展与领域相关,大学生较为关注职业领域,其次为人生观领域,而对政治和信仰领域兴趣较低;另外,大学生对友谊、交往领域较为关注,对性别角色和活动领域关注程度相对较低。
