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 microsturcture characteristics of M2 cast-strip were studied with such experimental methods as metallographic analysis, SEM, XRD and TEM[0]. The effect of sub-rapid solidification on the size, type and distribution of eutectic carbides in M2 cast-strip was analyzed. The effect of heat treatment temperature and its holding time on the eutectic carbides in M2 cast-strip was explored. The eveolution of metastable phase of M2C eutectic carbide during the heat treatment period and the decomposition dynamics concerned were researched. The M2 cast-strips were rolled into thin strips and the effect of deformation ratio on carbides in M2 cast-strip was examined. Then these thin strips were comparied with those that were produced by conventional technology on carbide, hardness, red-hardness and bend strength. At last the rolled M2 cast-strips were made into saw blades and their cutting performance was experimented on in tools factories and then compared with that of similar products produced by conventional technology.
