English,Translation,If one looks at technical on structural engineering ,one will find that the meaning of the space frame has been very diverse or even confusing. 如果一个人着眼于结构工程技术，他会发现空间结构的意义是非常多样化甚至于混乱的。,In a very broad sense, the definition of the space frame is literally a three-dimensional structure. 在一个非常广泛的理解上,空间框架的定义就是一个三维结构。,However, in a more restricted sense, space frame means some type of special structure action in three dimensions. 然而,在一个更受限制的观念中, 三维空间中，空间框架意味着某种类型的特殊结构功能。,Sometimes structural engineers and architects seem to fail to convey with it what they really want to communicate. 有时，结构工程师和建筑师似乎未能传达他们真正想要的,A space frame is a structure system assembled of linear elements so arranged that forces are transferred in a three-dimensional manner. 空间架构是一种由线性元素组装安排的结构系统，以促使其以三维的方式运行,In some cases, the constituent element may be two-dimensional. Macroscopically a space frame often takes the form of a flat or curved surface. 在某些情况下, 组成元素可能是二维的。宏观上空间框架通常都用平面或曲面。,It should be noted that virtually the same structure defined as a space frame here is referred to as structure. 需要注意的是，几乎相同的结构定义为一个空间框架。这里被称为结构。,A latticed structure is a structure system in the form of a network of elements (as opposed to a continuous surface). 一个网架结构是一个网络元素形成的一种结构系统（而不是一个连续的表面）与相对的,Rolled , extruded or fabricated sections comprise the member elements. Another characteristic of latticed structural system is that their load-carrying mechanism is three
