Compressibility is the fractional change in volume per unit increase in pressure. For each atmosphere increase in pressure, the volume of water would decrease 46.4 parts per million. The compressibility k is the reciprocal of the Bulk modulus, B. (Data from Sears, Zemansky, Young, and Freedman, University Physics, 10th Ed., Section 11-6. )
体积压缩性是压强增加单位量时体积的相对变化。每增加一个大气压,水的体积会减少46.4万分之一。体积压缩性k是体积弹性模量B的倒数。(数据来源:Sears, Zemansky, Young 和 Freedman,《大学物理》,第10版,第11-6节。) |
