conformal geometric algebra is a kind of new geometric representation and geometric computation tool, and it has properties of geometric intuitiveness, compactness, high efficiency, unification and elegance.

摘 要：共形几何代数是一种新的几何表示和几何计算工具，它具有直观、简洁、高效、统一、雅致等特性。

We also set up a Schur-Weyl duality between certain quantum group and Hecke algebra of type D_n.

我们还建立了某些量子群与D_n型黑克代数之间的Schur-Weyl对偶。

Zhang(1997) further generalized them to central duadic group algebra codes.

张胜元(1997)又进一步推广到中心duadic群代数码。

We point out the correspondences between Lie group, Lie algebra and some keyformulae of Huston-Kane method.

首次指出偏速度与偏角速度构成运动相空间的Lagrange子流形，揭示了偏速度与偏角速度的本质及Huston-Kane方法对动力学问题的变换思路。

In order to satisfy itself to as well as enriches my knowledge with the contemporary science hope, I have not only studied the machine science core curriculum like mechanics, the metal, the process and the material, but also through was the audit method has studied the other curriculum like discrete mathematics, the advanced algebra, the group theory in other and so on.

为了满足自己对与当代科学的渴望以及丰富我的知识，我不仅学习了机械科学的基础课程如机械学、金属、过程与材料，还通过在其他系旁听的方法学习了其他课程如离散数学、高等代数、群论等。

Atlast,we consider the tensor product representation of quantum group Uqslandthe representation of Hecke algebra Hwhich commutes with that of Uqsl.

最后，考虑了量子群Uqsl的张量表示及其与之可换的Hecke代数H的表示。

About the existence of duadic codes, Ward and Zhu(1994) obtained necessary and sufficient conditions for existence of duadic abelian codes, Zhang(1997) gave the existent conditions for such codes by some parameters and obtained necessary and sufficient conditions for existence of central duadic group algebra codes.

对duadic群代数码的存在性问题，Ward和朱烈(1994)解决了域上duadic阿贝尔码存在性；张胜元(1997)年用参数形式给出更具体的判定条件和中心duadic群代数码存在的充分必要条件。

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。
