This paper studies the electrode combination of 3D tunnel DC focused method. At first, the authors calculate and analyze the current distribution of two point power sources with the same electrical property, and indicate that as currents exclude each other, current density has a maximum at a certain depth along the perpendicular bisector of the two point power sources and the depth is directly proportional to the distance between them.

本文研究了三维坑道直流聚焦法电极组合，首先计算分析了两个同性点电源的电流分布规律，指出由于电流的相互排斥作用，电流密度在这两个点电源的中垂线下一定深度处产生最大值，这个深度与这两个点源之间的距离成正比。

The preliminary results show that the maximally evoked responses are at a deeper layer of the cortex. The value of this depth form surface of the cortex is about 900 m. A twodimensional recording was performed at this depth to find the responsive center or locus. The result shows that a dipole can be used to represent the responsive center with a coordinate of 1.9 mm posterial and 1.9 mm lateral to the Bregma. These finds should be valuable for further studies about pain.

The first rank derivative is a reflection of curve change and its rate, at certain range, if the sign of the first rank derivative has changed, the logging value of the correspondence depth point means maximum in this range; the second rank derivative is the knaggy property reflection of curve, at certain range, if the sign of the second rank derivative has changed, the correspondence depth point represent the inflexion of geophysical logging curve, it＇s also a turning point of the reflection of knaggy change property of the curve, it is the interface of stratum.

测井曲线的值是深度的函数，测井曲线的一阶导数表示了曲线变化的趋势和变化的快慢，在某一范围内，当一阶导数呈现符号转换时，相对应的深度点的测井值即为该范围内极大值；测井曲线的二阶导数则表示曲线的凹凸性，在某一范围内，当二阶导数呈现符号转换时，相对应的深度点代表了测井曲线的拐点，即反映曲线凹凸性变化的转折点，亦即地层的分界面。

The contents of N, P, K in leaves were examined by regular leaf analysis. The results showed that the N content was higher in leaf blade than in leafstalk. N content in leaf was gradually reduced along with the vine growth. N, F, K fertilized at 20 to 40 cm soil layers significantly increased N content in leaf. But N content in leafstalk was less affected by N fertilization depth and growing season. P content was higher in leafstalk than in leaf blade. Less change of P content was noticed in leaf along with vine growth. However, N, P, K fertilized at 40 to 60 cm soil layers significantly promoted P in both leaf blade and leafstalk. K content in leafstalk was much higher than in leaf Wade. No obvious influence was noticed by fertilizing depth. But K content in leafstalk was significantly increased due to applied K fertilizer in late growing season.

结果表明，酿酒葡萄叶片中氮含量远高于叶柄，叶片中氮素含量随着生育期的延长逐渐降低，而叶柄中氮含量随施肥深度增加和生育期延长而产生的变化很小，40cm的施肥深度能显著增加叶片中氮素含量；叶柄磷素平均含量高于叶片，全生育期叶片磷含量变化很小，而施肥60cm深度显著促进了叶片和叶柄中磷含量的提高；叶柄中钾含量远高于叶片，施肥深度对叶柄和叶片中钾含量未产生明显影响，但生育后期追施钾肥显著提高叶片钾含量；施肥深度达到40cm时酿酒葡萄的产量最高，而60cm的施肥深度产量显著下降。

Microphylla plantations are obvious, such effects and the contents of soil organic matter, N, P and K are gradually increased with the growth of C. microphylla plantations. Moreover, the activities of phosphomonoesterase, saccharase, protease, urease, dehydrogenase, polyphenol oxidase and nitrate reductase and the contents of edaphon C, N and P are significantly increased at soil depth of 0~30 cm, especially at soil depth of 0~10 cm.

From the angel of so-called political"essence"and"rule", the Cainozoic Era writers have not provided much depth for us. But from the angel of life politics, we can find"depth"in other dimension. If we ignore this"depth"and temporize it with excuse of"flatness", our comment will be at risk of invalidity.
