β-carotene showed slight protection of DR degradation of ACSS at a high concentration, and potent protective effects on DNA damage of ACSS at a lower concentration.

In control area of AC servo systems ( ACSS), the controller of ACSS generally adopts a control strategy in a control loop, narrow usage range becomes its shortcoming.

在交流伺服系统控制领域中，交流伺服系统控制器多为一个控制环一种控制策略，这导致了它的应用范围较窄。

For overcoming this defect, a reconfiguration controller of ACSS was proposed, each control loop consists of some control strategies.

为了克服这缺点，提出一种交流伺服系统可重构控制器的设计方法，该控制器的各个控制环由多种控制策略组成。

In the second chapters, describes the system design of the ACSS.

第二章介绍了伺服模拟器的总体设计。

At the same time, in handling the problem of large-scale topology map, we introduce a heuristic topology discovery algorithm ( ACTL). The ACTL algorithm cluster network nodes with ant-colony algorithm and configure the layout with 'tension-gravitation model'.

同时，为了应对大型网络拓扑布局的难题，提出了一种启发式网络拓扑布局算法-ACTL，利用蚁群算法对网络节点进行聚类，再利用张力&引力模型进行布局。

The results suggested that the expression of EBV was closely correlated to the histological type of NPC: keratinizing NPC was negative, while non keratinizing NPC was positive.

提示EB病毒原位杂交表达与NPC的组织学类型关系密切，角化型为阴性表达，非角化型为阳性表达。

Quantitative analysis of DNA content showed 30 speciments from trichoepithelioma were all diploid. While 16 of 30 specimens from keratinizing basal cell epithelioma were aneuploid.

毛发上皮瘤组30例均为二倍体，角化型基底细胞癌组有异倍体16例。

Results Primary nasopharyngeal carcinomas could be classified into four major types, namely keratinizing squamous cell carcinoma, non keratinizing carcinoma, adenocarcinoma and carcinoma in situ.

结果：鼻咽原发性癌可分为4种类型，即角化性鳞状细胞癌、非角化性癌、腺癌和原位癌。

SSCC tumor cells showed large cytoplasm, nucleolus more obvious, in order to find a squamous cell carcinoma of the overall hierarchical structure and the cell keratinizing;
