| Abstract | Increasing the driving frequency of piezoelectric vibrator can resolve the bottleneck of low flow of the valve piezoelectric pump. However, the using of piezoelectric pump of traditional valve body all presents the hysteretic nature of valve; macroscopic performance is up-frequency to flow-sharply. This research is to settle the bottleneck mentioned above: firstly, through the sub-experiment on various parameters of plate valve of piezoelectric pump, the reasons for how valve body itself can influence “up-frequency to flow-sharply”, which causes the hysteretic nature of valve, were discovered; then, E-shaped valve and piezoelectric pump with E-shaped valve (PPEV) were invented with purpose; finally, the efficiency of PPEV has been proved helpful to reduce hysteretic nature in experiment. Under the same conditions, the driving frequency of novel PPEV can be over 10 times higher and the flow rate can be also several times larger than traditional pumps. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
