第一部分，我们想利用状态和微分回馈控制把一个时变周期离散的系统正则化，在这部分我们找到一个可以正则化的充分条件，并利用构造方法证明在这充分条件之下可以构造出状态和微分回馈控制矩阵，使的这周期闭回路系统可以被正则化。

In this study, AlGaN/GaN hetero-junction photo-transistors in detecting ultraviolet spectra have been fabricated and characterized.

如何在已有的数据库中查询这些模糊信息，这就需要通过定义隶属函数、选择语气算子、确定系统阈值和误差限，对结构化的查询语言SQL进行模糊化处理，形成模糊化

Instead this paper focuses on the theoretical, analytical dimension and offers three theoretical, analytical explanations for the questions: 1 because the literary indigenization paradigm engenders a kind of antagonism between different historical narratives which is difficult to be weakened; 2 because in the identity politics strategic essentialism is ready to slide from a mere strategy to a form of de facto essentialism that provokes an essentialist backlash; 3 because the literary indigenization paradigm and the conflict caused by it, after all, involves state power.

因此本文另辟蹊径，从理论分析的角度提出三点解释：第一，由於文学的本土化典范是一种叙事的本土化典范，其相关的争论有如世界观的冲突；第二、由於认同政治∕文化斗争中的「策略的本质主义」与本质主义之间不易区分，即使是策略性的认同宣称，也容易引起本质主义色彩的对抗；第三，因为文学的本土化典范终究涉及国家权力。
