The system uses four layer construction design as wireless information collection layer, the mobile terminal information fusion layer, network data transmission layer, human computer interactive application layer. The original collection of computer-based spoken English translation information is taken based on host computer communication sensing information processing technology, Bus data transmission of English translation accuracy evaluation system is taken based on B/S structure, the test design process and remote scheduling information fusion are constructed based on LabWindows/CVl and B/S structure mining system, information data processing and cross compiler operation of the spoken English translation test evaluation system are completed in application layer, in the embedded kernel and on the wireless mobile terminal, the evaluation system is developed. The test results show that the integrated scheduling ability of spoken English translation test information system designed in this paper is better than traditional method, the cost time is less, and the control quality of the system is high.展开更多

However, the expression ofvasa gene during the reproductive cycle in ovoviviparous fish has not been documented. In this study, the full-length sequence of vasa was obtained from the ovary of Korean rockfish （Sebastes schlegeli） using reverse transcription-PCR and rapid amplification of cDNA ends. The Vasa with a mature protein of 650 amino acids showed greatest homology （84%） with giant gourami （Osphronemus gorarny） and Pacific bluefin tuna （Thunnus orientalis）. The expression of vasa mRNA in Korean rockfish was detected in gonads only, suggesting its specific role in gonadal development. In addition, seasonal changes in the vasa expression levels were examined in gonads by quantitative real-time PCR. The vasa transcript levels in adult testis were found higher during spermatogenesis than during spermiation. The vasa transcript levels remained relatively high at the early ovary stage but declined during ovary maturation in adult female fish. These results suggest that the vasa gene play an important role in spermatogenesis and early oogenesis during the reproductive cycle of Korean rockfish.展开更多
