能峰 meaning in English
energy hill
Examples
- The linear least square fit is used in energy calibration and geometry calibration , and the nonlinear least square fit is used in peak fitting and region fitting
其中能量刻度与几何刻度时采用了线性最小二乘法，而能峰拟合与谱段拟合时采用了非线性最小二乘法。 - Test results indicate that the flexibility of asphalt concrete can be increased at lower temperatures when polyester fibers are used , and the stiffness of asphalt concrete is reinforced at higher temperatures
结果表明，聚酯纤维掺入后能峰低沥青混凝土低温时的脆性，提高共高温时的劲度。 - In the analysis process , the six main peaks in 88 - 100 kev region , including the y peaks of 234th , the k peaks of th and the k peaks of u , are chosen . the smoothly joined gaussian function and low energy exponential tail is taken as peak shape function and quadratic polynomial is taken as background function . the two functions are fitted to gether to calculate the peak area
在分析过程中，选择了88 - 100kev能区的~ ( 234 ) th的射线峰， th的k _射线峰以及u的k _射线峰共六个主要能峰，通过采用高斯函数和低能指数尾部光滑联接的峰形函数和二次多项式本底函数一起拟合，来求出峰面积；而该能区所有能峰的探测效率可以认为是近似相等的，由此得到铀富集度。 - The encoding of the data by ann approach is a promising method for the measurement of uranium samples . the determination of the shielded uranium , in particular , by passive gamma - ray detection is a formidable challenge . gamma rays are ideal probes for determining the attributes of uranium in nuclear material transparency monitoring and verification of safeguards regime
2 % ;封装浓缩铀属性的判定一直是nda测量技术中的难点问题，本工作提出了一种辅助探测的方法并给出了高浓铀的判定依据，该方法通过探测232u衰变子体核素208t1的2614 , 75kev特征射线能峰确定铀样品中是否存在232u ,从而判定封装样品是否为高浓铀。
