查询词典 divided difference

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。

Methods: Cases were selected from patients with serious CHF accompanied by anemia, hospitalized between 2004 Augest and 2005 Augest, and divided at random into treatment group and control group; forwardlooking filing was adopted. Two groups were both rendered regular antiheart failure treatment; control group was added injection of RhEPO and ferrous obiect; after one year followup, difference in objective indices was compared.

选择自2004.8～2005.8月间住院的重度CHF伴贫血的患者，采用前瞻性队列研究，随机分为治疗组和对照组，两组患者均给予常规抗心衰治疗，治疗组加用重组促红细胞生成素注射及铁剂口服治疗，随访1年，比较两组在客观指标上的差别。

The ignition module can be divided into 2 types, id est: the capacitor discharge ignition module, and transistorized coil ignition module according to the difference of the energy storage element.
