悲劇包含了樂觀與悲觀，超越了兩者，反映了兩者，但是並不最終指向任何一方.的確，悲劇可以被認為是悲觀的，其原因在於它始終視世間的邪惡為永不止息和無法救贖的.然而那些悲劇人物卻是人類存在之必然疾患的證明.它是悲觀的，同時也在於它意識到在這世上惡相對于善是多麼強勢的存在，並且這一事實的不合理性也一直糾結在它心裏.這一深不可測的迷惘導致了以色列國王亞哈的沉淪.然而，悲劇又是樂觀的，因為其強大的生命力.這種在某種程度上神秘的，超乎世俗的生命力.它的樂觀性在於其對宇宙本質之良善的信心，在於其即使短暫，卻實在的，認為世間萬種疑惑終將被解答的信念First, it was taken that a discuss about the effects of geometry parameters of each piezocrystal on direction parameters ( main lobe width, side lobe amplitude, elimination of grating lobes ), amplitude of ultrasonic pressure, element viberation pattern, mutual radiation among elements, efficient test regions, ability to keep accurate and near - field distance and so on. based on the direction of ultrasonic field in ulpa deduced by ourselves. in addition, on the base of integrating all kinds of factors, it was put forward that the principle and method for optimized design of geometry parameters of piezocrystals in ulpa transducer, and its design programme and interface were compiled
