摘要：Based on experimental data of line heating, the methods of vector mapping, plane projection, and coordinate converting are presented to establish the spectra for line heating distortion discipline which shows the relationship between process parameters and distortion parameters of line heating. Back-propagation network （BP-net） is used to modify tile spectra. Mathematical models for optimizing line heating techniques parameters, which include two-objective functions, are constructed. To convert the multi-objective optimization into a single-objective one, the method of changifig weight coefficient is used, and then the individual fitness function is built up, Taking the number of heating lines, distance between the heating lines＇ border （line space）, and shrink quantity of lines as three restrictive conditions, a hierarchy genetic algorithm （HGA） code is established by making use of information provided by the spectra, in which inner coding and outer coding adopt different heredity arithmetic operators in inherent operating, The numerical example shows that the spectra for line heating distortion discipline presented here can provide accurate information required by techniques parameter prediction of line heating process and the technique parameter optimization method based on HGA provided here can obtain good results for hull plate.

摘要：这所新教教堂由四个主要建筑单元构成：圣殿、社区会堂、圣器收藏室和雕塑钟塔。建筑的形状像一张巨大的＂桌子＂,整个屋顶被四条＂桌子腿＂（四根钢柱）支撑着。屋顶及其三个醒目的天窗是本建筑的重要构件。外皮由焊接在框架结构上的8毫米厚立体弧形钢板构成。屋顶构件的建造采用了造船技术。勒·柯布西耶（Le Corbusier）在将造船技术运用到建筑方面起了重要的示范作用,这同样还包括他建造的拉图雷特修道院。前院的雕塑钟塔高20米,是一个垂直框架的自承重钢结构。
