As a result, it comes to two kinds of intention structure: one is intention structure in phenomenology, with its language logic ""S" is "P""; the other is intention structure in Speech Act Theory of Austin and Searle, which is made up of psychological model and description of content in form of "noun + intentionality + clause".

在此基础上形成了两种意向结构：一是现象学范畴活动的意向结构，其语言的逻辑形式是"S是P"；二是奥斯汀和塞尔的言语行为的意向结构，它是由某种心理模式和对内容的描述所构成，其语言结构是"名词性的词+意向词+从句"。正是从"S是P"这一语言的基本逻辑结构出发，语言的意向构造的基底才真正被找到。

Based on the method of multi-objective fuzzy optimization and the overhead traveling crane design, a mathematical model of fuzzy optimization for main box beam section is established. A fuzzy goal anthology is constructed. The fuzziness of multi-objective function and constraints is defined. The transformation of the fuzzy constraints set to normal constraints set in real number domain is realized by applying optimal level cut set method. The optimal solution and optimal constraint value of sub-objective function in the feasible field are found using the genetic algorithms.
