Hydraulic pile hammer is one of the pile driving machines that drive prefabricated piles into the ground in the construction of pile foundation such as construction, bridge, dock, etc. with the development of science and technology, the prefabricated pile driving machines evolve from block hammer, steam - hammer, diesel hammer to hydraulic hammer. hydraulic pile hammer is one of ideal prefabricated pile driving machines because it can adjust stress waveform, decrease stress peak value, prolong effectual action when it drives piles. hydraulic pile hammer is used widely and formed series in developed countries now
液壓打樁錘是用於建築、橋梁、碼頭等樁基礎施工中打入預制樁的樁工機械。隨著科學技術的進步，預制樁施工機械由落錘、汽錘、柴油錘，發展到了液壓打樁錘。用液壓打樁錘打樁，可以調整撞擊應力波波形，減小應力峰值，延長有效作用時間，是一種比較理想的預制樁施工機械，目前在發達國家已被廣泛使用，並形成了系列化。 -
In this paper, the general structure of block cipher together with its related properties is firstly discussed, then the main non - linear component of s - boxes in block cipher is analyzed. as to the boolean function in binary field, we studied its non - linearity, linearity structure, output bit independence criterion ( big ), balance, completeness, strict avalanche criterion, propagation criterion, correlation immunity, linear approximation table and xor distribution table. we also discussed the pile - up lama used to compute the combination linear probability and showed an instance of its application
本文首先討論了分組密碼的一般結構及其相關特性，此外還有分組密碼主要的非線性組成部分s盒。對於二元域上的布爾函數主要討論了其非線性性、線性結構、比特獨立準則、平衡性、完整性、雪崩準則、傳播準則、相關免疫性、線性分佈表及異或分佈表等特性。對計算組合線性概率的迭加定理我們也進行了具體的討論，並給出了運用事例。
