Let μ be a smooth measure with a quasi regular Dirichlet form, A μ be its non negative additive functional,and U α A μ be the α Potential operator of A μ.

设μ是拟正则狄氏型的光滑测度，Aμ是其对应的非负连续可加泛函，UαAμ是Aμ的α位势算子，本文证明了测度μUαAμ关于μ的绝对连续性，并以R－N导数dμUαAμdμ刻划了μ具有有限能量积分的条件。

Based on the physical meaning of each term in the linear parameter log I (a constant correlating the affinity of solut e t o stationary phase) of stoichiometric displacement model for retention o f solute, the thermodynamic characteristics of log I of solute in revers ed-phase liquid chromatography were investigated theoretically. This poi nt was tested by experimental data with two linear relationships:(1) plot of log I vs 1/T with apolar, polar small solut es and proteins;(2) plot of log I vs log Po/w (partition co effi cient of solute between n-octanol and water) with apolar and polar smal l solutes.

依据液相色谱中溶质计量置换保留模型及线性参数log I(与1 mol溶质对固定相的亲和势大小有关的常数)，通过作图得知非极性和极性小分子溶质及生物大分子的log I与绝对温度的倒数1/T，以及小分子溶质的log I与其在正辛醇-水中分配系数的对数log Po/w呈线性关系，从两方面进一步证明了log I具有热力学平衡常数的性质。

The result shows that the mixed boundary condition can greatly reduce the calculation area without affecting accuracy of the solution.It is followed by the higher accuracy of Dirichlet boundary condition which makes the boundary error greater when measured points is near the boundary, so we must take a sufficiently large border region.The homogeneous boundary condition has relatively large error, but the use of non-triangle poles devices makes apparent resistivity calculation error become small, because of elimination of the effect on potential difference for the infinite boundary. In inversion, in order to save computing time, homogeneous boundary conditions are often used to perform finite element forward calculation.

结果表明，混合边界条件精度最高，可大大缩小求解区域而不影响计算精度，其次是Dirichlet边界条件精度较高，但测点越靠边界误差会越大，必须取足够大的边界区域，齐次边界条件的误差比较大，但如果采用非二极装置，通过电位差计算得到的视电阻率，由于无穷远边界对电位差的影响基本消除，视电阻率计算误差与混合边界条件下的接近，在反演中，为了节省计算时间，经常使用齐次边界条件进行有限元正演。

In addition to the kinds of individuals older than, another two kinds of land locked lamprey, that is, the Northeast lamprey (L. morii, English name: Yalu River Lamprey) and river lamprey (L. reissneri, English name: Asiatic brook lamprey), but were considerably smaller than the individual, life-long habitat in the river, the non-migratory habits, the numbers are small, are in a Vulnerable status.

除了以上的个人，另外土地的两种锁定鳗种，即东北鳗（湖栎，英文名称：鸭绿江鳗）和河流鳗（湖，英文名称reissneri：亚洲布鲁克八目鳗），但大大低于个人，生活在河长的栖息地，非迁徙习惯的人数较少，正处在一个脆弱的地位。

But the result of improvement soil translated alkaline soil into alkalier soil. Not onlu it is unavoidable and subsisted of stabilization in commix tier of gypsum, but also it destroyed direct improvement process. It is imported find what solved seepage problem of gypsum in the study. In configured duality structure of improvement soil, it needs abundance seepage gypsum in commix tier into noncommix tier in order to losing seepage capacity reduce in all deepness of improvement soil.

碱土改良过程中石膏渗漏损失最高可达到石膏施入量的40%以上，而改良结果碱土只转化为重碱化土；在石膏混合层内，它是一种不可避免的、稳定存在的且直接破坏土壤改良进程逆流；因此解决石膏渗漏问题亦是在本文研究工作中的重要发现：配置二元结构改良碱土中，正需要石膏混合层中大量石膏渗漏，以改良非石膏混合层，并使整个计划改良深度内的渗漏损失降为零。

At the beginning, it was substantial money acting as the intermediary of transactions. Then it developed to be token money, In the 1970s, the Bretton Woods Regime collapsed. Us dolor wasn"t related to gold and gold didn"t serve as money. Money gradually changed its form from token money to credit money, totally abstract value symbol. At the end of the 20th century, the development of science and technology and the speed of economic integration have accelerated.

从最初充当交换媒介的实物货币，发展到了铸币和银行券——代用货币。20世纪70年代，随着布雷顿森林体系瓦解，美元脱离黄金、黄金非货币化，货币也逐渐从价值实体向完全抽象的价值符号——信用货币进行转变。20世纪末，随着科学技术的发展和经济一体化进程的加快，货币形态演变的速度也在加快，人类社会正经历着从纸币向电子货币过渡的重要时期。
