nuclear density

Thirty sets of ND-50 nuclear density gauge have been trial-produced or reproduced, and applied to control the quality in roller compacted concrete dam ( RCCD). for at least 5 γ 105 m3 in more than ten hydraulic and hydroelectric projects.

试制和改进试制了30套ND-50核子密度仪，应用于十余个水利水电工程碾压混凝土坝的质量控制，总方量超过5×10~5m~3。

By using adjacent index, geographic concentration index, Lorenz curve and nuclear density analysis method to analyze the spatial distribution characteristics of leisure agriculture demonstration sites in Hubei province, and reviewing agricultural tourism spatial distribution characteristics in Hubei province.

通过运用最邻近指数、集中化指数、洛伦兹曲线、核密度分析等方法对湖北省休闲农业示范点空间分布特征进行深入分析，揭示湖北省农业旅游空间分布特征。
