General View of Discourse Analysis——from the perspective of FLT & FLL

Discourse analysis has been extensively applied in many aspects of language research .It can be useful analytic tools for foreign language teachers to make necessary changes in instructions. Base on the teaching practice, the paper suggests for the foreign language teachers a very useful four-stop process to help investigate the interaction patterns in their classrooms and to watch how these patterns promote or hinder opportunities for foreign language learners to practice the target language.     

Labor Reform in Mexico,Analysis of Principal Changes and Method of Recruitment

Actually, the country＇s development aims to achieve higher levels of productivity, so it had to adapt to international standards. This has served to ease the hiring of both operational and managerial controls, giving emphasis on training and allowing the pairing boss-worker to take the productivity like benchmark. The labor reform allows companies to make changes with their workers; such changes must be reflected in lower costs for businesses, by labor input and increased competitiveness, however, two years ago this guideline was implanted and society asks if the results are congruent, because Mexican society is undergoing economics problems issue as well as a deficit in generating jobs. Therefore, analyzing whether modifications made to the federal labor law （FLL） are designed to optimize safety of workers and enterprises in which they work is the subject of this research. The corresponding analysis was performed using the deductive method.

采用锁频环和锁相环联合捕获的载波跟踪

针对传统锁频环-锁相环跟踪算法中环路状态转换过渡中出现频率阶跃的问题,提出了一种采用锁频环和锁相环联合捕获的方式替代单一锁频环进行捕获的改进算法,同时对环路状态转换的门限进行了推导。仿真结果表明,改进的算法在转换过程中更加平稳,环路性能得到了优化。在信噪比为-10 dB且存在加加速度时跟踪环路在转换时没有出现频率阶跃,达到了设计目的。
