The electric,thermal and general energy efficiency of amorphous silicon photovoltaic/thermal design which was cooled by natural ventilation was 4.

Analysing comprehensive efficiency and tapping potential of equipments;

A field survey and analysis on the data from water pumps in bottom hole at Jiaoxi coal mine are presented and a variety of factors effeted on the comprehensive efficiency of water pumps are discussed Therefore, some proposals for the reformation and improvement on water pumps have been put forwar

Research on overall efficiency of Chinese port-typed listed companies;

Based on the non-Archimedian infinite model C~2R of the Data Envelopment Analysis,combined with characteristics of Chinese mainland banks inputs and outputs,the paper sets up an index system of inputs and outputs as well as an overall efficiency evaluation model for Chinese banks,which considers not only the profit ability,but also the control capacity of banks risk.

Application of the grey relation projection method on fuzzy valuation of comprehensive efficiency of the near distance weapon systems;

Index system of warship equipment conceptual design was established and comprehensive effectiveness was put forward to describe operational capability and logistics support capability.

The shortages of statistical theory used in the research of effectiveness evaluation in weapon systems are pointed out first, the concepts of fuzzy measure and fuzzy integral are defined, the comprehensive effectiveness evaluation formula and the process based on fuzzy measure and fuzzy int.

The superiority of non-linear fuzzy comprehensive evaluation method was analyzed,comprehensive effectiveness evaluation index system of certain three anti-aircraft missile guidance system was established,and the example was analyzed by using the established evaluation model,which is expected to provide an effective evaluation method to guidance and control system of anti-aircraft missile.
