A block design is a triple d = ( x, b, i ), where x is a finite set ( the point set ) of order v, b is the block set and / is the incidence relation between x and b. for the given block design d, if all the blocks from x, which have the same type of the blocks in b, can be partitioned into some bi, such that each ( x, bi, i ) is a block design with the same parameters and the same type as d, then { ( x, bi, i ) } i is called as large set of d - design of order v. on the other side, let | x | = v, | y | = v + 1, and x y, if all the blocks of the same type from y can be partitioned into some bx, such that each ( y { x }, bx, i } is a block design of order v for any element x y with the same parameters and the same type as d, then { ( y { x }, bx, i ) } x is called an overlarge set of d - design of order v. in this thesis, we discuss the existence problem about some types of large sets and overlarge sets
一個區組設計是由兩個有限集合x ， b及它們之間的關聯關系i組成的，記為d = （ x ， b ， i ） ，其中x為v元集， b為區組集，對于指定的設計d ，若x上與d相應的全部構形可分拆為若干個b _ i ，使得每個（ x ， b _ i ， i ）皆為一個與d同參數同類型設計，則稱這些b _ i構成一個v階d -設計的大集。若v元集x是v + 1元集y的一個子集，而y上與d相應的全部指定構形可分拆為若干個b _ x ，使得每個b _ x恰是y { x }上的一個與d同參數同類型的設計（其中x y ） ，則稱這些b _ x構成一個v階d -設計的超大集。本文中討論了一些區組設計的大集及超大集。 -
The conclusions are as follows : the ultrasonic intensity is proportion to the laser intensity ; the ultrasonic induced by a laser line source has much more advantages than by a laser point source, such as stronger energy, higher snr, more directivity and shape ; the intensity of cfpi ' s output signal is linear with ultrasonic vibration velocity, and is effected by incidence angle and scattered angle ; snr will increase by reducing cfpi ' s bandwidth, reducing incidence angle, increasing cavity ' s length and reflectivity
在分析點光源激勵聲表面波機理的基礎上，求出了線光源激勵的超聲振動的位移表達式，發現線光源激勵的近場區表面波具有波形好，信噪比高，指向性好，幅度強等特點。通過理論推導，得出共焦fabry - perot干涉儀的輸出光強除了與樣品表面的振動速度成正比，並與入射角和散射角有關；適當減小cfpi的帶寬，增加腔長，增大鏡面反射率，或者減小檢測入射角都可以提高系統的信噪比。 -
