求翻译：压缩试件轴向与材料的发泡方向一致，中、高密度试件尺寸为直径25mm，高25mm；低密度的试件尺寸为，试件尺寸比胞体大二个数量级，可代表真实材料的宏观力学性质。实验在万能材料试验机上进行，中高密度泡抹的变形由电子引伸仪测量 而低密度泡沫的变形由横粱位移确定。实验温度，湿度。是什么意思？

Compression specimen axis and the material of the foam in the same direction, the high density of the specimen size of diameter 25mm high 25mm; low density of the specimen size, specimen size than the cell body, two orders of magnitude can represent the real material macroscopic mechanical propertie

Compression test specimen materials with the foam in a consistent, high-density test specimen size diameter of 25 MM, 25 mm high; low-density of the test specimen size is, test specimen size is larger than the maximum 2 brother, representative of the real magnitude of macroeconomic dynamics material

The compression test sample axial is consistent with the material foaming direction, the high density test sample size is diameter 25mm, high 25mm; The low density test sample size is, the test sample size is bigger than two magnitudes the cell body, may represent the real material the macroscopic m

Axial compression test parts and materials of foam line, medium and high density and diameter of specimen size for 25mm, high 25mm, low density of specimen size, sample size two orders of magnitude larger than the cell body, represents the macroscopic mechanical properties of real materials. Experim
