By using thenatural boundary element method which is set up by professor Feng Kang,the Neu-mann boundary problem of the harmonic equation on the half-upper plane is reducedto the Hadamard type singular integral equation,the integral region of which is un-bound,and then we turn it into corresponding bilinear form.

通过由冯康教授开创的自然边界元方法，将上半平面调和方程的Neumann边值问题归化为Hadamard型强奇异自然边界积分方程，并且此积分方程是无界域上的强奇异自然边界积分方程，然后将它转化为相应的变分形式。

By transforming the interlace series type linear differential equation with coefficient containing binomial coefficients and arrangement number into the linear differential equation of successive integral,the theory and method for solving this kind of equation are determined.

The weather had changed, and the snow, which had for the last few days been looming blackly in the frosty sky, fell in great feathery flakes against the windows, and lay piled in the little bit of garden ground without.

天气已经变了，最近几日黑沉沉地出现在严寒天空的雪意，现在化为鹅毛大雪落下来了，飘在窗子上，堆积在外边儿的一小块花园地上。

Math class is in session, let's sum this up: With the the word from BonBon and Mike, the lack of concert ads and unavailable tickets online, it looks like Hov in Shanghai ain't happenin'.On brighter Jay-Z news, the ace is back.

少年的Shawn Carter独自撑起了他和母亲的生活，不久他就成了街头一名普通的黑人说唱歌手，最初的时候他为自己取了一个源自爵士乐的名字"Jazzy"，不久之后简化为Jay-Z。

The bond and angle terms are usually modeled as harmonic oscillators in force fields that do not allow bond breaking.

Then by matching the traction along the branches and the boundary of the strip, Cauchy singular equations were obtained, in which the point dislocation and the distributed dislocation density served as the unknown function.

根据板条边界和裂纹面上的应力边界条件，建立以集中位错强度和分布位错密度为未知函数的Cauchy型奇异积分方程，利用半开型积分法则将该奇异积分方程化为代数方程求解。

If you let yourself be broken, you will have no place in either, but merely return to the dust; or, at best, you may secure a corner in a bric-a-brac cabinet--as a curiosity, and it is more glorious far to be used for fetching water by the meanest of village women.

假如你让自己破损，你将无处可去，仅仅终将化为尘土，或是，你最多将在破旧的储藏柜中占据一角，而这比帮卑劣的乡下女人挑水好得多。
