例句與造句

1. On the basis of simplified calculation model presented by doctor wangxiaoping , some finite element models are set up . by finite element model program sap93 , an analysis of static models of 18m - span and 30m - span w666 acmr in different supporting conditions is made . also a study on the relation between definite support displacement , which reflect variational stiffness of substructure represented by steel column or reinforced concrete column , and load - carrying capacity mechanical performance is made too
   本文以w666金屬拱型波紋屋頂為研究對象，沿用王小平博士的簡化計算模型，對18m 、 30m跨波紋拱兩端不同支座形式(鉸支、固支和彈性支座)分別利用有限元計算程序sap93進(jìn)行計算分析，研究波紋拱在不同跨度，不同支座形式下，不同外荷載作用時對該結(jié)構(gòu)受力性能及穩(wěn)定承載力的影響，同時分析下部支承鋼柱、鋼筋混凝土柱的剛度變化體現(xiàn)為允許支座位移的大小與結(jié)構(gòu)受力性能及穩(wěn)定承載力之間的關(guān)系。
2. It's difficult to find support displacement in a sentence. 用support displacement造句挺難的
