variational

Then a power supply equipment is developed based on this draw-out coil. Integral test results illustrate that the power supply provides stable outputs with no saturation and low heat consumption throughout the variational range of the transmission-line currents.

基于此取能线圈研制了一台电源，整体测试表明，电源能在导线电流正常变化范围内工作于非饱和、低热耗状态，并提供稳定的输出。

Second order elliptic variational inequalities were considered, and a kind of nonoverlapping domain decomposition method with two subdomains was proposed.

考虑二阶椭圆变分不等式，提出了两子域情形的非重叠区域分解，得到了算法的收敛性和几何收敛速。

Compound forecasting methodology in a position to via to analyze forecasted indices multiangular in depth, gain much relevant data variational inherent law, thereby work out preferable forecast. Secondly, research on comprehensive utilization multiple data mining method proceed short term load forecasting.

复合预测方法能够通过对预测指标的多角度分析，获得更多有关数据变化的内在规律，从而做出更加科学的预测。（2）研究了综合利用多种数据挖掘方法进行短期负荷预测的方法。
