The paper presents a kind of hardware and software design of digital automatic subsynchronous parallel generator experimental facility.

After analyzing the componential conditions,balanced placement,and notional characteristics,the paper holds that parallel formatting is the outcome of comprehensive functions of both internal and external conditions.

In the process of abbreviated mobile power station s parallel connection,frequency measurement is the key and basis of the parallel connection.

This paper analyzes causes of common troubles in synchronous generator operation,especially those such as non-simultaneous concatenation for generators,excitation-loss,stator winding damage,rotor winding earthing,pressure-boosting difficulty and overload operation and puts forth appropriate measures to solve them.

According to practical production, this paper synthetically used concatenation,idle column,quasi-level experimental design and multitude-comparison AnOVA to seek for the optimum technics of cement production.

“Soreni, sosite, sorekara, mata" are common Japanese conjunctions, which can all be used as linguistic markers of coordination, addition, internal linkage and so on.

For comprehensively promulgating its structure control actions, this article takes the relations of coordination structure and connective marker as example.

This paper, by distinguishing semantically syntactically and pr agmatically the coordination and upgrading, tries to explore and explain the con ditions for their mutual transformation the semantic determinants, the syntactic restrictions and the pragmatic selections in their transformation.

And provide theoretical support for assuring transformers in juxtaposition safely and economically circulate.

Redundant systems of each element are analyzed comprehensively,and the fully parataxis hot standby redundancy and cross-standby redundancy are compared.
