无压的

The structure-acoustic coupled models of Santana2000 are built both with and without absorption material, and ANSYS finite element analysis software is used to calculate interior acoustic pressure due to panels vibration under specific frequency, then the acoustic contribution of panel is evaluated.

以桑塔那2000型轿车为实例建立无吸声材料和有吸声材料的结构-声学模型，使用ANSYS有限元分析软件计算车身板件在给定频率下振动引起的车内声压，进而求得板件的声学贡献。

The experimental results reveal that there is no apparent difference in the frequency of sounds generated by the friction and collision between two stones, although the sounds may differ in pressure.

由实验结果可知，摩擦与撞击这两种不同的运动机制所产生的地声音频讯号，除声压强度上会有显著的差异之外，其在频谱上并无太大的差异性存在，这可能是因为摩擦运动基本上也可视其为无数个小撞击运动，因此其所产生之地声声纹基本上大同小异。

By means of the non-linear finite element analysis,the defect-free tee under bending moment was researched in this paper.

The contrast is caused by changing the pressure on the pen, not because of the form of the pen. bodoni is one example of this, but also sans serif faces like helvetica have this origin.

其笔画的粗细对比是通过改变笔压来实现的，而与笔尖本身的形状无关。bodoni字体就是一个例子，但是象helvetica这样的无衬线体也是来源于此。

Bronchospasm occurred in 12 patients and resoloved after inhalation of bronchodilator and intravenous administration of corticostreoid.

术前呼吸减退的COPD肺癌患者并非外科手术的绝对禁忌症，术前锻炼和围手术期无创正压通气支持有助於术后呼吸功能的锻炼和康复。
