As a result of analysis to many of the results of experiment, checked up on specimens, field investigation and combining with the theories of palaeobotany, comparative morphology, evolutional morphology of vascular plants and taxonomy, it can be concluded as following: the primitive sorts of Cycadaceae are the sorts that pinnate leafs are dichotomy; among these, the sort that pinnate leafs are tripinnate-dichotomy is most primitive, from this sort gradually evolve to bipinnate-dichotomy, to only for monopinnate-dichotomy, from this sort evolve to the sorts that pinnate leafs are simply pinna; among the sorts of simply pinna, the species that segments of megasporophyll possess much more triplicate to monodichotomy are most primitive.

经过大量的实验结果分析、查阅标本和野外调查，结合古植物学、比较形态学、演化植物学和分类学等理论进行分析，认为苏铁科原始的类型为羽叶呈二歧状分叉的种类，其中最原始的又是羽叶呈三回二歧状分叉的种类，从这个羽叶类型逐渐演化出一回二歧状分叉的羽叶类型，再演化出羽叶为单羽状的类型；而单羽状叶的类群中，又以大孢子叶侧裂片具三回、二回及一回二歧状分叉数量多的种类为最原始，而侧裂片二歧状分叉数量少的为较进化，侧裂片无二歧分叉的如拳叶苏铁类为最进化的种类。

Using the estimates of character sums over Galois rings and the trace de scription of primitive sequences over Zpe, we obtain an estimate for the frequency of the occurrences of any element in Zpe in one period of a primitive sequence, which is better than Kuzmin's results[1] if n ＞ 4e, where n is the degree of the generating polynomial of the primitive sequence.

The management and quality analysis of the primitive images have been analyzed and studied in this paper, of which the content and structure are as follows:Firstly, the developing background and the meaning of the management and quality analysis of the primitive image, as well as the trends of the management and data quality of the image database studied both in and out of our country, have been discussed in detail.Secondly, the developing direction of the technology of the remote sensing image and the importance of the remote sensing images in the field of economy nowadays have been analyzed systematically. And it is pointed that the primitive image with the elements of interior and exterior orientation will become more and more important as a sort of image production.Thirdly, the hierarchical structure of database, especially the SQL Server adopted in this system, has been deep studied and analyzed in the aspects of Applying Program Interface, Internet Data Connector and ActiveX Data Object.Fourthly, the methods of assessing the quality of the remote sensing image have been put forward in the terms of geometry, construction and the integrality of the assistant information.Fifthly, the model of propagation of errors of the precision of the ground coordinates has been calculated in the steps of inner orientation, spatial resection and answering based on the deep analysis of the principles and processes of inner direction and space resection, which have also been experimented and analyzed in term of numerical value.Finally, the total design and the idiographic realization of the sub-modules have been introduced in detail, based on which the design and development of this system are realized in combination with the program languages such as VB6.0, VC6.0 and SQL.

The phylogenetic trees supported that Eriocaulaceae be treated as Eriocaulales because this family always been a nature independent group connected with other families. Eriocaulaceae grouped with Commelinaceae, which supported the close relationship and parallel evolution between the two families. Juncaceae was not close to Eriocaulaceae and more primitive. The relationship between Juncaceae and Cyperaceae was closer than that between Juncaceae and Poaceae. Among these families, Poaceae was the most primitive family and far from Eriocaulaceae. Also in Eriocaulaceae, Eriocaulon was supported to be more primitive.

从构建的系统发育树可以得到：①谷精草科独立形成一个植物类群，支持谷精草科独立成为谷精草目；②谷精草科与鸭跖草科聚成一个大的类群，说明两科的亲缘关系较近，并且表现为平行进化；③灯心草科不近缘于谷精草科，与禾本科相比，灯芯草科与莎草科之间存在更近的亲缘关系；④在进化程度上，灯心草科比谷精草科原始；禾本科与谷精草科的亲缘关系最远，并且在这几个科中处于最原始的进化地位；⑤系统树还支持谷精草科内部的系统关系，支持谷精草属在谷精草科中的原始系统位置。

The Chinese ancient theatrical costume 's genesis relates to the origins of the Chinese Ancient Drama and the Chinese ancient clothing. Since the Chinese Ancient Drama comes of the primitive men 's roll playing and the Chinese clothing comes of the primitive men 's dressing themselves up. So the Chinese ancient theatrical costume comes of the primitive men 's primping up themselves for roll playing.

中国古代戏剧服饰的起源与中国古代戏剧和中国古代服饰的起源都密切相关，戏剧起源于原始人的角色扮演，服饰产生于原始人对自身的装饰，因此，中国古代的戏剧服饰起源于原始人通过装饰自身而进行的角色扮演。

The definition of the absolute value for a fuzzy number is obtained.Furthermore,a lot ofproblems,such as absolute integrability,bounded variation and absolute continuity,arepresented and discussed.The representation theorem of the absolute values of fuzzy num-bers is established.It plays an important role in discussing the problems conceming theabsolute value.The relation between the absolute integrability and integrabili-ty is discussed,and the following result is obtained:aintegrable fuzzy-number-valued function is absolutely integrable iff it is integrable.The relation between theabsolute integrability and the absolute continuity of the primitive for fuzzy-number-valuedfunctions is dealt with.It is also pointed out that a fuzzy number valued function is ab-solutelyintegrable if and only if its integral primitive is fuzzy absolutely continuous.
