珍珠泉

矿泉水厂沟的翡翠泉是典型的酸性岩溶冷泉，含水层水的径流较珍珠泉慢且滞留时间相对长些，含有一定的CO2，系一深部含水层地下水的露头。

The Jadeite Spring is a typical acidic karst water cold spring . The flow velocity of the water in the Jadeite Spring aquifer is slower than that in the Pearl spring , and its water hence has relatively long detained time .

珍珠泉和翡翠泉为沟内出露的主要泉水；

Pearl spring and Jadeite spring are major spring resources in this spot .

济南珍珠泉井水固有振荡试验的解释

Explanation of natural oscillation of water level in the well Pearl Spring in Jinan

本文介绍了济南珍珠泉井水固有振荡试验结果。

A test of natural oscillation of water level in the well Pearl Spring in Jinan has been carried out .

该系统阻尼系数小，角频率恰好和瑞利波角频率相近，因此珍珠泉井水位对地震瑞利波响应的振幅特别大。

The damping factor is smaller , and the angular frequency just is close to the that of Rayleigh 's wave .

计算出珍珠泉水井-含水层系统的阻尼系数和固有振动的角频率。

On the basis of the test the damping factor and angular frequency of natural oscillation cf the well aquifer have been calculated .
