用灰色GM(1,1)模型对陕西省GDP 做预测
本文先用灰色GM(1,1)模型对陕西省GDP 做预测, 经过检验, 再用此模型确定另外一些未知指标, 最后通过确定的这些指标用
灰色GM(1,N)模型作预测, 通过比较总结两种模型各自的特点, 从而科学的指导陕西省经济发展,国内生产总值预测模型具有重要的现实意
义。
(This article first gray GM (1,1) models do forecast GDP of Shaanxi province, on examination, then this model to determine other unknown targets, and finally through the identification of these indicators of gray GM (1, N) model for prediction, by Comparison of two models summarize the characteristics of their own, so the guidance of scientific economic development in Shaanxi Province, China' s GDP forecast model has important practical significance.)

将接地长导线源沿导线方向分解成多个电偶极子源，对若干电偶极子源产生的响应进行叠加得到接地长导线源的Hz响应。计算结果表明接地长导线源的Hz响应与电阻率之间的关系也为单值关系。(Decompose the grounded long wire source along the wire direction with several electric dipole, and overlay the response which produced by the electric dipole as the grounded long wire source’s response. The result show that the relationship between the Hz component of ground long wire source and resistivity are also single valued.)

Adaptintegral
辛普森公式的自适应积分：在整个积分区间使用相同的小步长 ，以保持整体精度。然而，实际应用中，函数的振荡起伏的情况处处不同，这并没有考虑到曲线的某些部分变化剧烈，需要比其他部分多加考虑的情况。而有些部分，曲线的变化缓和，因此可以采用大于平均值的步长 来进行积分。因此，引入一种能够在函数值变化大的区间采用小步长的方法是很有用的。这种方法，称为自适应积分。(Adapt integral based on Simpson integral)
