A wide spectrum analyzer is being acquired for use in a project involving the nonlinear oscillations of gas bubbles in a fluid. It was discovered that the frequency components emitted by these bubbles can be described in a theoretical manner. These analytical results are being tested by acquiring a general purpose instrument--a spectrum analyzer--to obtain experimental measurements of these frequency components.

正在购买一台宽谱分析仪，用于涉及流体中气泡非线性振荡的项目。 人们发现这些气泡发出的频率分量可以用理论方式描述。 这些分析结果正在通过获取通用仪器（频谱分析仪）进行测试，以获得这些频率分量的实验测量结果。
