According to Sarkovskii's theorem, if the continuous self-map f of the closed interval has a 3-periodic orbit, then f must has an n-periodic orbit for any positive integer n But f can not has all n-periodic orbits for some n.

但f不可能有所有类型的n-周期轨。例如：则f仅有两种类型的3-周期轨中的一类。这表明Sarkovskii定理远远没有给出周期轨之间的关系的全部信息。

Theorem Let be continuous on a bounded closed region in the -plane.(1) If is given by and , where are continuous functions of on, then

定理 设在xy平面上的有界闭区域 D 上连续，(1)若区域由和所给出，其中是上的连续函数，则。

The closed shell HF SCF calculations have been carried out for the electron transfer systems corresponding to different values of R, then the Koopmans' theorem is applied to estimate the energy level splitting △, and the relatonship between △ and R has been obtained.

对该电子转移体系进行闭壳层的单点计算，并用Koopmans定理计算了体系的分裂能△，得到△随线性反应坐标R的变化关系。

On the basis of previous theory, the paper puts forward the organization pattern of cluster-based innovation, aiming at studying the deficiency of innovative resources of single company in middle-small enterprises cluster from the point view of theorem.

在已有理论的基础上，论文提出了集群式创新的组织模式，旨在从理论上研究集群内单个企业创新资源不足的问题。

Local codimension two bifurcation of maps,associated with Hopf-pitchfork case,is analyzed using the center manifold theorem and normal form method of maps.

应用映射的中心流形和范式方法，研究了映射在Hopf-pitchfork余维二分岔点附近的参数开折，揭示了含间隙振动系统在余维二分岔点附近的动力学行为。

The recent research has shown that the network coding can make this theorem realized in multicasting network environment.

近来研究表明，网络编码可以使这一理论在多播方式的网络环境中得以实现。

The performance boundaries are acquired through coding and coding theorem.

通过编码和编码定理得到一些重要的性能界限。

ABSTRACT This dissertation presents the author′s research contributions to joint source-channel coding theory and the joint coding theorem...

本文介绍了作者在信源—信道联合编码研究方面所作的主要工作，包括联合编码理论和联合编码算法两部分内容。

The dissecting of samples in group2 were difficult. The root of pulmonary artery and ascending aorta failed to be unfolded because fibrous tissue was tough, right and left fibrous trigone were too firm to be solved by hand. Cardiac muscle fibers couldn't be stripped along myofibrillar trajectory since they were prone to break because of their friability.

组2的心脏解剖困难，表现为纤维组织坚韧，游离肺动脉非常困难；徒手无法松解左、右纤维三角，肺动脉和主动脉根部的游离非常困难；心肌纤维坚硬、质脆，解剖时容易断离成碎块，无法沿纤维走行方向剥离。

We have battled against the odds in a province that has become increasingly violent.

我们对在一个争夺日益激烈省的可能性。
