摘要
研制了一种基于金刚石对顶砧的液体高压黏度测量装置。该装置由金刚石对顶砧、显微镜和CCD探测器构成,利用红宝石荧光标定压力,通过落球法可简单方便地实现不同压力下液体黏度的测量。利用该装置,测量了高压下丙三醇的黏度,测量结果与已发表的实验数据吻合得很好,验证了测量装置的可靠性。
We developed a device for measuring high-pressure viscosity of liquids. The device consists of a diamond anvil cell,a microscope and a CCD detector, by which pressures can be determined using the ruby fluorescence technique. It is simple and convenient to measure the viscosities of liquids under different pressures with the falling-ball method. Using this device, we successfully obtained the viscosities of glycerin under high pressure, which are in good agreement with the published data, suggesting that our measuring device and method are both reliable.
