This thesissets out to discuss the nature of reading and the characteristics of informational texts,and then identifiesprior knowledge deficiency as a major cause for failure to comprehend informational texts.

From following four inner factors of student which influence strategy use, the paper analyses the reasons of the production of "utilization deficiency" of learning strategy: prior knowledge, attributions, self-efficacy and cognitive monitoring.

After that,we systematically reviews the research on opportunity discovery patterns,and then we summarize the influence of opportunity discovery patterns on the newness of opportunity as well as the moderating role of prior knowledge,which aim to show the direction for entrepreneurship research and real practice in this field.

Whole flow optimization based on prior knowledge in chemical process;

Incorporating prior knowledge in fuzzy least squares SVM model and its application;

Application of sample prior knowledge to nerve networks training;

Combining with the conductivity distribution information of human tissue and organ,an image reconstruction method of electrical impedance tomography based on pulmonary prior information was proposed using conjugate gradient method.

Then the sensitivity matrix was solved by commercial simulation software COMSOL considering the structure and resistivity of lung,the prior information was adop.

It s pointed out by this paper that the priori knowledge of random rough soil surface is needed in soil moisture inversion by using passive remote sensing, so the precision of priori knowledge has effect on the inversion result.

To accelerate the learning speed, bias information is incorporated to boost learning process with priori knowledge.

Via anatomising study mechanism between information searched and priori knowledge,we have inquired into optimized paths during multi-pe.
