The integral area ' s shape can be arbitrary, its shape is the intersecting part of physical grid and mathematics grid, so, the generation of integral area of unit is an intersection operation of two polygons
摘要由數學覆蓋和物理網格形成的流形單元的積分區域可以有任意形狀，其形狀為物理網格和數學網格的相交部分，所以流形單元積分區域的形成為兩個多邊形（數學網格和物理網格）的求交運算。 -
Focusing on the problem of sound field of scattering due to the existence of tubes, the general mathematical model modeled according the condition of plant, and then the coefficient of sound scattering is resolved by using the method of inverse matrix, the functions of arbitrary configuration of tubes is got, the far field scattered pressure and near field scattered intensity of the unit of heat exchanger tubes is calculated, at last, the effect of soot cleaning due to the existence is analyzed
論文根據爐內管束的實際情況，建立換熱器管束聲波散射的通用數學模型，利用迭加原理法求解模型中的待定散射作用系數，得出任意布置管束的散射聲場特性，並具體計算鍋爐換熱器管束單元聲波散射遠場聲壓分佈和近場壁面的聲強分佈，最後分析由於聲波的多重散射作用而對聲波吹灰的影響。 -
At last, these functions are used to advance sha - 1, and a new hash function called csha is proposed. unit 4 : at present, cryptography hash algorithm for applications such as digital fingerprinting of messages, message authentication, and key derivation is commonly iterative processed which hash inputs of arbitrary length by processing successive fixed - size blocks of the input. the iterative process is commonly serial construction
在系統分析了雜湊函數機制后，我們利用j . seberry等人提出的方法，構造出了同時滿足平衡性、高度非線性及嚴格雪崩特性的並且容易實現的雜湊輪函數，並利用這些雜湊輪函數，在原sha - 1雜湊函數的基礎上，設計出了新的雜湊演算法csha 。
