A kind of non-contact high precision nuclear densimeter was developed.

研制了一种非接触式、高精度核子密度计。

The article briefly introduces the operating principle of vibrating densimeter.

叙述了振动管式密度计的工作原理。

This method provides a simpler, more accurate and reliable way to calibrate densimeter on the spot.

本方法为核密度计的现场率定提供了一种简便易行、准确可靠的新途径。

Regression coefficient between sensor and densimeter is 0.997, The sensor response remained stable for at least 8 days.

传感器与糖度计法测定的相关系数为0.997。传感器至少可以稳定使用8天以上。

After roller compaction, the wet density of RCC would be measured by sampling from the digged pit or by nuclear densimeter.

碾压后，挖坑取样或采用核子密度水分计选点测量碾压混凝土的湿密度。
