Then the waveband was divided into two parts to develop calibration model using partial least square method for soluble solids content to remove the effect of the skin and the results indicated that the measurement results was not be enhanced. However, the difference of calibration results in the wavelength of 650-950nm with the r of 0.949, the RMSEC of 0.292 for intact watermelon and with the r of 0.973 and the RMSEC of 0.214 for skin-peeled watermelon indicated that the influence of skin is not very serious and the intact watermelon spectra also can get satisfied calibration result. 5. Vis/NIR spectroscopy nondestructive detection needs high-energy light source, so differences of diffuse transmittance spectra with different light intensity (600W, 1000W) were detected and effects of light intensity on spectra and calibration results were compared.

针对西瓜果皮较厚的特点，对去皮西瓜与带皮西瓜进行对比试验研究，发现果皮对光谱的影响主要集中在可见光部分(650-750nm)，对可溶性固形物含量采用偏最小二乘法进行分段建模并没有有效消除果皮的影响，对比研究去皮西瓜与完整西瓜光谱在650-950nm范围内的建模结果，完整西瓜二阶微分光谱校正模型相关系数r为0.949，RMSEC为0.292，去皮西瓜校正模型相关系数r为0.973，RMSEC为0.214，果皮对建模结果的影响并不严重，完整西瓜的建模结果可以满足检测要求； 5。

The scintillation CsI was also calibrated with protons of 15, 20, 23MeV. The average energy calibration is 1. 047MeV per channel. Energy calibration for heavy ions was completed with multiplication factor 1/12. 75. The energy calibration is around 1. 1MeV per channel for oxygen ion and iron ions when energy deposition is less than 50MeV in each detector.

对铁离子而言，铁离子的四个能量点在ΔE〓探测器中的能量均超过50MeV，能量信号放大电路此时已进入饱和状态，当铁束能量为120MeV时，离子进入到ΔE〓探测器中，此时在ΔE〓中能量沉积低于50MeV，没有达到电子学系统的饱和值，能量刻度每道为1.1MeV／道，这些与氧离子的标定结果是一致的，饱和只是对于低能重粒子会出现这种情况，对于中高能重离子这种现象就会消失。
