The permanent magnets are now mouthed at the exterior of the high-pressure vessel and are no longer in contact with the fluid sample. So this construction of equipment decreases the contamination of each other. Concerning the temperature-control system, the present instrument employs one non-vibrating new technology. In the high pressure systems, a simple and fast high-pressure pump was used to generate hydraulic pressure. This equipment is more easy to control than the literature\'s methods. A digital lock-in amplifier has been used as sinusoidal current function generator and the induced signal detector.

本文对振动丝粘度密度仪在设计方案上进行了大量改进，把磁体从高压容器的内部移植到容器的外部，提高了容器的化学适应性，采用了无振动的恒温新技术，利用了方便快捷的加压方式，极大的方便了实验的进行，减少了实验的工作量，用数字Lock-in锁相放大器作为驱动信号发生器和诱导信号检测器，设备既简单又极大地提高了信号的检测灵敏度。
