Based on the definition of Boolean function on set and positive extension, The sufficient and necessary condition of PBF is proven. At last, an algorithm of generating MSP expression of stack filter positive Boolean function is presented taking advantage of Hasse diagram.

通过定义布尔函数开、闭集和最小项正、负扩展，证明了布尔函数具有层叠性的充要条件是布尔函数开集的正扩展或闭集的负扩展具有不变性，在此基础上，提出了一种通过Hasse图确定层叠滤波器最简正布尔函数的算法。

Mathematic proof of the hypertonicity for this model is given using two different cases. Furthermore, the Riemann invariants for the multi-class traffic flow LWR model are studied by using characteristic line method, and the physical interpret of the Riemann invariants are also pointed out. The information in transfer is obtained, that is, the total density and the relative density hold the same.

用两种方法给出了该模型在不同情形下双曲性的数学证明，运用特征线方法研究并计算了任意等级MCLWR交通流模型的Riemann不变量，得到了其传递的交通信息，给出了Riemann不变量物理意义的解释，即总密度保持不变和相对密度保持不变，最后又从形式上指出了在多等级车流并行时，MCLWR与LWR两种交通流模型实际上是等价的。

In order to determine the Poincare normal form of linear operator in the operator differetial equation, we need to reduce the vector-value function to the two dimensional case on center manifold.

要证明以上的结论，我们所采用的方法是[24]中的Hopf分支定理所给出的判断Hopf分支存在性及分支周期解稳定性方法。

Everted sac experiments were carried out using viable segments of rat intestine for comparing mucoadhesive characters. The swelling behaviors were also examined and further investigation of release mechanism indicated that ketoprofen calcium pectinate gel beads were different from calcium alginate gel beads.

利用大鼠肠囊外翻实验对凝胶小球的生物黏附性能进行比较，通过对释放机理的探讨和凝胶小球溶胀性的测定进一步证明2种凝胶小球释药行为的不同。

We have demonstrated that the renatured Escherichia colioverexpressed RpoⅠ can reconstitute with Rhizobium core RNA polymerase in vitro. A preparation procedure has been established, which is expected to be useful to further functional study.

我们证明了大肠杆菌表达变复性的RpoⅠ能够与根瘤菌的核心RNA聚合酶在体外重组成全酶，并建立了成熟的制备方案，为以后阐明RpoⅠ的功能奠定了基础。

This paper examines 10 asp ects of the Right to Keep Silent, 1 pinpointing the differences between the right to keep silent and the right of not being coerced into criminal confession; 2 arguing that the rule of all criminal behavior is made so by statute, the protection of human rights and the equality of the defendant and the plaintiff cannot justify the right to keep silent; 3 no

本文通过十个方面对沉默权制度相关问题作了分析，揭示了沉默权与不被强迫自证其罪特权之间的不同点，指出无罪推定原则、人权保障原则和控辩平等原则不能成为沉默权制度具有正当性的理由，而且沉默权制度缺乏道德基础，不能与我国刑事诉讼证明标准和坦白制度并存，不能有效遏制刑讯逼供，也不利于实现实体公正，并对在有关沉默权制度的讨论中存在的"程序本位主义"倾向作了批驳。

This paper has investigated the expression on rotational motion of earth's surface and Earth's deformation fields with complex vector surface spherical harmonic function, theoretical definition of the crust-fixed reference frames and the terrestrial reference system, and theoretical substantiating to the consistency between them.

徐州师范大学国土信息与测绘工程系，徐州 221116；2。中国科学院测量与地球物理研究所，武汉 430077摘要：本文研究了内核地球模型下的地球表面的旋转运动和地球形变场的复数矢量球函数表示，以及外壳固定参考架、地球参考系的理论定义和它们之间等价性的理论证明。

Only after proving her self-sufficiency to herself can she marry Rochester and not be asymmetrically dependent upon him as her "master."

只有在对她自己证明她的自足性之后，她能与罗贾斯特结婚，不是作为她的紫苑的倚赖他的asymmetrically。

Candidates who are confident with their responses at the beginning of the interview will likely remain confident in giving you honest and candid answers even as the questions become more probative and demanding.

在面试开始时对他们的答复就有信心的应试者，也会很有信心的向你表明他们的意愿，即使是问题变得越来越有证明性和有更多的要求。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
