A variatioual calculation of the energy of the-2s2 is state of helium has been carried out with the use of a wave function of the Hylleraasian typo. The wave function is where s,t u are in units of 4 times the first Bohr radius of hydrogen.

本文以变分法计算2s~21~S态氦原子之能量，所用之波函式，即：=e~(-0.2278s){1-0.17079s-0.063155u-0.013869t~2 +0.010044u~2+0.0064785s~2}上式中之s，t，u均以4倍於氢原子之第一Bohr半径为单位。

在分析Windows系统和Linux系统启动流程的基础上，给出了制作基于U盘上的Linux恢复平台和基于光盘的Windows恢复平台的方法。

Gutniska'' shows a number of similarities with Gothic which are not shared by other Old Norse dialects: lack of a-umlaut in short high vowels ( e.g.''fulk'': Old Icelandic ''folk''), lowering of '' u '' to '' o '' before '' r ''( e.g.''bort''), the use of '' lamb '' with the sense "sheep", the appearance in both of an early Germanic loanword from Latin ''lucerna''( Gothic ''lukarn'', Old Gutnish ''lukarr''), and, arguably, the preservation of the Proto-Germanic diphthongs *''ai'' and *''au''.

Gutniska''和哥德语有著许多不见於其他古诺斯语方言的相似处，如在高短母音里不具有 a 变音(如''fulk''这个字与古冰岛语的''folk''的对比)、在'' r ''前面'' u ''到'' o ''的低音化、以「羔羊」的字来指代「绵羊」、早期日耳曼语的拉丁语借词''lucerna''(哥德语''lukarn''、古顾特语''lukarr'')的从在，以及具争议性的一条，也就是原始日耳曼语双母音*''ai''和*''au''的存留。

He also was tasked with the job of countering any U-boat threat and to begin planning an invasion of the Bosporus.

他还负责对付任何U艇的威胁的工作，并开始规划的入侵博斯普鲁斯海峡。

Finaly, in the case of the nonlinearities being singular at 0, by utilizing the mountain-pass theorem and some other variational methods, we get the existence of nontrivial solutions of the equations under the Dirichlet boundary condition, where the operator diva(x,u is the p-Laplacian.

最后，我们通过应用山路引理等变分方法，研究当算子diva(x，▽u为p-Laplacian并且非线性项在原点有奇异性时，方程在Dirichlet边值条件下非平凡解的存在性。

R~n(n≥0) is a bounded domain with smooth boundaryΩ;ΔisLaplace operator; u and v, respectively, denote populaton densities of prey andpredator species, inhabit the domainΩ; a_i, b_i, c_i, D_i(i=1,2) are positive constants.the form of boundary parameter B is?

R~n(n≥0)是边界Ω充分光滑的有界区域；△为Laplace算子；u，v分别表示区域Ω中食饵和捕食者的密度，参数a_i，b_i，c_i，D_i(i=1，2)均为正常数，而边值参数B形式为这里的？

In order to effectively abstract the texture and denoise but not damage the edge and other important details of image, Meyer (2001) proposed using elements of BV space and G space to characterize cartoon and details of image respectively. The authors present PDE of minimizing energy on the basis of Meyer's work, After the model is discretizated. projection algorithm and the method for ROF model are applied. Thus an image is decomposed into two parts, bounded variation component u and texture with noise υ.

为有效地提取纹理和去噪而不损坏图像的边缘及其他重要细节，Meyer(2001)提出了分别用BV空间和G空间刻画图像的主体和细节部分，笔者在Meyer的图像分解模型基础上，建立能量最小化PDE方程，将模型离散化后，利用投影算法和ROF模型的求解方法，将图像分解为有界变差部分u和包含纹理和噪声的部分υ。
