Note that regularized problems are usually defined in an infinite setting and have to be discTetized for an implementation and there have been many comparatively adult methods of calculating singular system. Therefore, there is no need to avoid the calculation of singular system in inverse problems calculating of numeric value. Here TSVD Regularization Method is very simple and quite effective one.

考虑到反问题的数值计算需要将问题离散化，化为有限维的问题来进行处理，而对于有限维算子的奇异系的计算已经有了相当成熟的各种算法，因此在反问题的数值计算中没有必要避开奇异系的计算，此时TSVD正则化方法是十分简单并相当有效的正则化方法。

The biographical facts are swiftly sketched and subjected to skeptical inquiry; the patriotic "jingoism" of his stirring ceremonial hymn beginning "By the rude bridge that arched the flood," for example, is minimized by Buell's conclusion that "Emerson's own concern was with values that stand the test of time and unite the world."

传记部分被很快地勾画出来并且包含了尚未定论的疑问；比如，爱默生以"简陋的拱桥边下河水流淌"为肇始的礼仪赞美诗所激起的爱国"沙文主义"在贝尔的结论中被简化为"爱默生自己对经受住时间的考验和联合全世界的价值的担忧"。

First of all, the structural analysis under the action of random loads is carried out and the mean value and variance of all joint's displacement and bar's stress in the structure are obtained by means of three fundamental equations (equilibrium, physical and geometric) in structural mechanics, as well as the property of moment of random variable.

通过引入可靠性安全系数，并利用结构力学的三个基本方程，将结构的位移和杆件应力可靠性约束等价显示化为设计变量的线性函数，使原基于可靠性的优化模型转化为常规的序列线性规划问题，利用修正的单纯形法求解。

这一问题又被具体化为以下四个问题：(1)是什么力量或显在或潜在地影响着哈萨克女性教育，使其在塑造女性角色上发生了变迁？

Damien Rice was born on the outskirts of Dublin in the early 70's and grew up in Celbridge Co. Kildare. He spent much of his childhood down by the River Liffey fishing...hours of catching little left plenty of time for thinking...

"Damien Rice声音的渲染力，甚至可以将歌曲的情绪化为实质，然后直接传到听者的心上，他对乐器的感觉和协调性也非常出色，可能是他小时候学过画的缘故，除了专辑封面和内页的插图出自他手之外，在他的吟唱之下，那些背景音乐仿佛组成了一幅异常美丽的图画。"

On the basis of classical lamination theory and large deflection hypotheses of plate, the equilibrium and compatibility equations of simply supported composite laminated plates were obtained. The nonlinear partial differential equations are transformed into the ordinary differential equations of Kronecker tensor product by series expansion and solved numerically by the fourth-order Runge-Kutta method.
