The traditional virtual boundary integral expression is based on the extension of single layer potential, for the integral formulas related to single layer potential for parabolic problem, the numerical computation of the exponential integral function is unavoidable.

通常的虚边界积分公式是利用单层位势的延拓来建立虚边界元积分方程，但对带时间变量的单层位势，要涉及到指数积分函数的计算。

All these profit from using the carbon nanotubes with large surface and proper pore distribution as the cathode, which ensure the TiO_2 nanowire anode precede with the faradic reaction in the applied potential range. The hybrid supercapacitor exhibits improved power and energy performances by the increased potential window, particularly in the larger current density.

电化学性能的改善得益于以较大比表面积和适当孔径分布的碳纳米管为正极，在电极／电解液界面处发生静电吸附存贮大量电荷，促使TiO_2纳米线电极可以在较为宽的电位窗口内通畅地进行对应的法拉第反应，维持其优异的电容性能，这将在一定程度上改善了混合超级电容器的功率密度和能量密度，尤其在较大的电流密度下更有优势。

The oxygen potential in ferromanganese melt is reached to a certain value about 5 min.Then the oxygen potential changes only in a narrow range.

脱硅过程中氧位在5min内迅速增加到一定值，5min后锰铁中的氧位只是在很窄的范围内变化。

Fourth, the market potential for potential mining.

四、挖掘潜在的市场潜力。

In the research and analysis of this Meiyu front system, several new views are suggested which are different from previous results, for example, the problems concerning the cut-off of high potential vorticity region, the formation mechanism of Jianghuai shear lines, the frontogenesis mechanism of Meiyu front in different positions, the affection to potential vorticity coming from air mass change.

7在对梅雨锋进行研究和分析过程中，对以前一些科学家所做的某些工作和结论做了进一步分析，提出了几点新见解。如高位涡区南下切断问题、江淮切变线形成机制问题、梅雨锋不同位置的锋生机制问题、质量变化对位涡的影响等。

Additionally, some trace elements in coals, which indicate the paleoclimate and the types of bog in coal-forming period, can also show hydrocarbon generating potential of coal, such as Cu which has a strong affinity to organic macromolecule in coals. Cu is a fades element, and may be an indicator element of hydrocarbon generating potential.

其中Cu既是一个有着与煤的大分子物质较强亲和力的元素，又是一个可以显示古气候古成煤沼泽类型的"指相"元素，因而在指示煤的生烃潜力方面可能具有普适性。
