Paradoxically, we're also hurt by a freer Chinese press: some quasi-private Chinese tabloids have the capitalist instinct, and because of the fervor to sell papers they are the ones with the most jingoistic stories.

有趣的是，自由度比以前更大的中国报业也在损害着美国--有些具有私营性质的小报具有了资本主义的特征，它们为了扩大销量而登载了一些最为好战的文章。

The Holy Office, however, bad exclusive control in foro externo over all impediments connected with or juridically bearing on matters of faith, eg disparity of worship, mixta religio, Holy orders, etc. The dispensing power in foro interno lay with the Penitentiaria, and in the case of pauperes or quasi-pauperes this same Congregation had dispensing power over public impediments in foro externo.

For five decades, Arafat -- adorned with his trademark checkered kaffiyeh -- was the most prominent face of Palestinian opposition to Israel and the push for a Palestinian state, first as the head of the Palestine Liberation Organization, which carried out attacks against Israeli targets, and later as the leader of the quasi-governmental Palestinian Authority after parts of the West Bank and Gaza were returned to Palestinian control.

50年来，戴着标志性的方格子头巾的阿拉法特是巴以冲突和巴勒斯坦建国运动中的最引人注目的面孔。阿拉法特最早是袭击以色列目标的巴勒斯坦解放组织的领袖，后来西岸和加沙的部分地区重归巴勒斯坦控制后，阿拉法特成为半官方的巴勒斯坦民族权利机构领导人。

The smaller fullerenes C2n (2n 60) violating IPR, inevitable suffer large strain energies and show high lability. Besides that, quasi-fullerenes violating the classical definition, contain rings of other size, for example 4 or 7, are expected to suffer extra local strain or/and further loss ofπdelocalization, and thus highly unstable.

碳原子数少于60的小富勒烯，和结构中含有除五元环、六元环之外的其他结构的准富勒烯，由于不满足IPR规则，结构中必然存在较大的张力，因此具有较高的化学活性，难以在实验中合成和分离。

The alternative estimators used in this paper include least squares estimator, stratified weighted least squares estimator, probability weighted least squares estimator, and Quasi-Aitken weighted least squares estimator.

中文摘要抽样调查设计随著资讯需求的增加日益复杂，然若参数的估计方法无法配合所使用的抽样调查设计，则统计推论结果将难以达到预期的精确度。

Sufficient conditions for existence of positive periodic solutions of these systems are established and we investigate a stochastic Lotka-Volterra ecosystem, by use of the mixed quasi-monotone theory and Liapunov function method, some new results are obtained.

最后，我们研究了n种群随机Lotka-Volterra生态模型，利用混合单调流理论和It〓型随机微分方程知识，得到了其解过程的均方渐近稳定性和强生态稳定性的结果。

In Chapter 4, using the formula A_k(2) given by Wei, we propose a new A_k(2)-SQP method, which develepments the using of the quasi-Newton formula BFGS, and combines with SQP method to solve constrained optimization problems, the corresponding algorithm possesses global convergence and supei linear convergence property.

第四章，利用韦提出的A_κ(2)公式，我们给出了一种A_κ(2)-SQP方法，该方法把拟牛顿修正公式BFGS进行了推广，并结合SQP方法去解约束优化问题，相应的算法具有全局收敛性和超线性收敛性。

There have been a lot of studies this aspect when the exact solution u∈H~2 or u∈H~3. [4], [52] and [50]studied the convergence of conforming linear triangle elements with minimal regularity assumptions u∈H~4, here u is the solutions of the second order elliptic problems. However, their is another vital deficiency of the previous studies, i.e., they relies on the regularity assumption or quasi-uniform assumption on the subdivision of meshes.

对二阶问题，构造了一个新的单元格式，当其精确解具有低正则性时，在不要求网格满足正则假设或拟一致假设的条件下，我们得到了最优误差估计，与[33]相比，我们的证明方法较为简单；对于Stokes问题，研究五节点非协调矩形元对它的逼近，通过引入全新的估计方法，给出了关于速度、压力的超逼近性质。
