The results showed the cultivation by selecting cottony or cottony with synthetic fiber bag, using the straw and 30% fish-pond soil, spraying a solution rational with NaOH of 100 mg/kg, can make volvariella volvacea grow faster, and may achieve 28% higher biological efficiency, with better product quality and shorter harvest intervals in it.

Mycelial growth characteristics,growing period,fruit body morphology and biological efficiency of four Agaricus bisporus strains were compared in order to select a high quality strain of A.

The effects of different media on mycelium growth,fruitbody yield and biological efficiency of Pleurotus eryngii were studied.

Increasing rate and biology efficiency were determined.

An empirical study on effect of soft technology on learning efficiency;

Demonstrative Study on the Factors in Students Mathematics Learning Efficiency;

Differences in Learning Efficiency between Mathematical Disability Students and High Ability Students in High Schools;

This research aims at inquiring into the different background music s influence on the study efficiency to middle school student under the identical condition.

Most students do not realize that self supervision of study has direct influence on their study efficiency.

In the study of Chinese, making full use of the advantages of the transference law will help improve our study efficiency, even obtain the aims of "drawing inferences of other cases from one" and "teaching the students how to fish".

The paper establishes a model on how to evaluate the scheme to improve children s studying efficiency which has been planned the by the educators (the scheme is called briefly efficiency scheme in the following),and how to get the best efficiency scheme with the excellent ability of operation.
