File ： set of related records treated as a unit , stored on tape or disk ; synonymous with data set
文件：作为相关记录的单元集合，存储在磁带或磁盘上；与数集同义。
As a result , the concept of state space for conceptual design of mechanical system is presented , which is new to the literature , based on the set of all state vectors . meanwhile , the properties of state vectors , which are vectors addition , constant multiplying , reversible driving , zero vectors , are discussed in state space . secondly , the dual - vector is introduced to descript the essential relation among the input and output characteristic vectors as well as sms
按照状态空间中对偶特征矢量的运算规则，在已知系统的输入输出特征矢量的情况下，通过数学推导求解，将形成的系统状态变换矩阵分解为多个状态变换矩阵的乘积，再通过各状态变换矩阵到数据库中寻找相应的基本变换单元集合，然后进行按序组合，进而从理论上获得相应的方案设计可行解。
