Example Sentences:

	1.	The conclusions obtained as follows : firstly , the structure ' s free frequency is decreased by the reduction of the mechanical property of the material with the increasing temperature ; secondly the thermal stress produced by the temperature gradient may decrease or enlarge the structures natural frequency ; thirdly , the variety of natural frequency of the alloy structures effected by the heat effect apparently higher than that of the composite material structures 最后，采用ansys程序分析了合金材料、复合材料的板、弹体结构的热振动特性。在不同的热载条件下，取得以下结论：升温导致的材料机械性能下降都会降低结构固有频率，而温度梯度产生的热应力可能降低也可能提高结构的固有频率；金属材料结构的固有频率受温度的影响要比复合材料结构的固有频率受温度的影响要明显。
	2.	The main contents of this paper is according to the structural characteristic of forced vibration , making use of the varying quantity data of free frequency of two different physical cantilever beam on the structural damage experiment basis , then using the bp network , genetic algorithm and the genetic bp algorithm to build up relation model between position , extent of structural damnification , and the varying quantity of free frequency 其主要内容就是根据结构受迫振动特性,利用试验测得两根不同物理性质悬臂梁在受损伤产生裂纹前后的固有频率改变量,使用bp网络、遗传算法、遗传bp算法,建立了结构损伤的位置、程度与结构固有频率损伤前后改变量之间的关系模型。
