Abstract | Annealing effects on the tree initiation voltage of high density polyethylene (HOPE) are studied. Three annealing methods with different cooling velocity were used in preparation of the samples. The samples cooled in high velocity were reheated and recooled. The crystallinity of these samples was measured. Recrystallization process was found. Put samples in oil with high temperature. For the samples cooled in low velocity and normal velocity, tree initiation voltage decreases with temperature increases. For samples cooled in high velocity, when the heating temperature is higher than 90 /spl deg/C, tree initiation voltage increases abnormally and then decreases with heating duration in high temperature. In addition, tree initiation voltage of samples increase and then decrease with heating temperature increases. We presumed that the morphological microstructure and the recrystallization processes in samples are responsible for above phenomena. |

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.
