Illinois,"It is useless to argue about taste and even more useless to litigate it", and that is the case here, the jury has already determined that this is a matter of taste, not matter of law, because they've said there is no libelous speech that nobody could reasonably believe that Hustler was actually suggesting that Jerry Falwell had sex with his mother.
Illinois一案中,您自己曾说过,"争论品味问题是没有意义的,更不要说因此而提起诉讼",本案陪审团已经认定这是一个品味问题,而不是法律问题,因为他们已经裁定本案没有诽谤的言论,没有一个理性的人会相信,《皮条客》杂志说Jerry Falwell跟他母亲乱交是真的。

All was unexpected. Likin, though, was temporary tax that the Qing Dynasty established for raising money to repress the taiping rebellion. It had been censured for seventy eight years. This showed that the existence of likin had its profound background of economy and society. Abolishing likin was to "change a little, then influence the whole", and it existed contradiction not only between China and other countries, but also between the center and the local authority. The problem of likin systems abolition was the problem about not only economy but also politics.
厘金虽然一开始是清王朝为筹措镇压太平天国运动军费而设立的临时税种,但其屡遭非议却长达78年的历史表明,厘金的存在有其深刻的经济与社会背景,"裁厘"可谓是"牵一发而动全身",不仅存在着中国与各国列强之间的矛盾,而且存在着中央与地方政权之间的矛盾,厘金的裁撤问题,既是经济问题,又是政治问题。

Illustrations are used to analyze the limitation of line sampling firstly. For linear limit state, the efficiency of LS is affected by the dispersion of the actual important direction from the optimal one, the bigger the dispersion is, the lower the efficiency is. For non-linear limit state, in case that the actual important direction deviates from the optimal one greatly, the efficiency and the precision of LS decrease seriously, even wrong results are obtained.
首先通过算例分析线抽样方法存在的问题,对于线性问题,线抽样法的效率受抽样重要方向与最优重要方向偏离程度的影响,这种偏离程度越大,效率越低;而对于非线性问题,当抽样重要方向与最优重要方向偏离较大时,线抽样的效率和精度均严重下降,甚至得出错误的计算结果。

For the original infinite dimensional problem, if the inexact quasi-newton method with Broyden updating can not converge quickly , for example, it can not attain super linear convergence rate , then when the discretization is becoming finer and finer , we can not get fast convergence rate for the corresponding finite dimensional problem.
对于原来的无限维问题,如果使用不精确Broyden方法不能得到较快的收敛速度,比如超线性收敛性,那么当离散化逐渐加细的时候,对于所得的有限维问题使用不精确Broyden方法也不可能得到较快的收敛速度,所以有必要在无穷维空间上对收敛性问题加以分析,从而为不精确拟牛顿法结合投影法求解算子方程做好准备。

The forth algorithm is the same as the third one with an addition of finite termination criteria. Although the latter two algorithms have only linear rate of convergence, they are especially suitable for large-scale and sparse problems, with features of simple formula, small storage, sparsity preservation and easy implementation.
前者借助NCP函数把互补问题转化为等价的非光滑方程组,再用带参数的光滑方程组近似这些非光滑方程组,最后用牛顿型方法求解所得到的光滑方程组,希望通过光滑参数趋于零得到原来互补问题的解;后者基于等价不动点格式,构造了一个光滑迭代算法和一个具有有限终止性质的算法,虽然这种迭代算法仅有线性收敛速度,但由于其格式简单、存储量小、保稀疏性、非常易于计算机实现等特点,故较适用于求解大规模稀疏问题。
