Studies on functional genes involved in larval settlement and metamorphosis in the small abalone Haliotis diversicolor

杂色鲍（Haliotisdiversicolor）是我国南方水产养殖的重要养殖种类。附着变态是杂色鲍早期发育过程的关键时期，幼虫敏感而脆弱，其变态成功与否将影响到种群分布和数量变动。因此研究杂色鲍幼虫附着变态相关的功能基因对于深入揭示幼虫附着变态分子机制具有重要理论意义，并为生产实践提供指导。 本文从实验室构建的杂色鲍转录组数据库中，克隆获得了与GABA相关的四个基因的序列片段：glutamicaciddecarboxylase、GABAAReceptorζsubunit、GABABReceptorα1subunitandGABAAReceptorρsubunit，分别命名为HdGAD、Hd...The abalone Haliotis diversicolor is one of important molluscs for aquaculture in China southern sea area.Larval settlement and metamorphosis is a key stage in the early embryo development of Haliotis diversicolor, and effects its population distribution and dynamics of its population, which is on the account of the sensitive and fragile condition.Thus,Studies on functional genes involved in larva...学位：理学硕士院系专业：生命科学学院_细胞生物学学号：2162013115256

Simulation and Fabrication of 4H-SiC Separated Absorption Charge and Multiplication Ultraviolet Avalanche Photodiodes

4H-碳化硅（SiC）紫外雪崩光电探测器（APD）已具备取代紫外光电倍增管和Si基紫外光电探测器的可能性，它在光纤通信、高保密的非视距紫外通信及微弱紫外信号检测等特殊领域有重要的应用，已日益成为国际上光电探测领域的研究热点。 近年来已报道的高性能4H-SiCAPDs大多是采用吸收层和倍增层分离结构（SAM）进行制备。虽然SAM结构具有较高的量子效率，但是为了实现有效的吸收层和倍增层分离结构，要求倍增层厚度较薄且掺杂浓度较高，这将会使得器件的暗电流较大且倍增层电场分布梯度过大，不利于雪崩机制，并导致器件雪崩击穿电压过大。为了解决这些问题，本论文改进传统4H-SiCSAM（p+nn-n+）结构，...High performance 4H-SiC ultraviolet (UV) avalanche photodiodes (APDs), as a potential candidate to replace UV photomultiplier tubes and Si-based UV photodiodes, play an important role in the fields such as optical fiber communication, non-line-of-sight covert communications and low-level UV detection, which have increasingly become an research hotspot in the photoelectric detection field.

近25 a 银川市城市化进程中热力景观格局演变分析

Abstract： Based on the Landsat images and statistical data，in this paper the urbanization process and thermal landscape dynamics of Yinchuan City were analyzed． The objectives of this study were as follows: ① To analyze the spatial and dynamic characteristics of urban thermal landscapes based on the landscape pattern index; ② To assess the influence of the urbanization process on the thermal landscapes; ③ To understand the relationship between the land use pattern and the land surface temperature ( LST) based on the distribution index． The results showed that there was a significant heat-island effect in Yinchuan City，and the high temperature area was consistent with the built-up area and the unused land． LST declined from the downtown to the suburbs，and an obvious difference of the dynamic characters of the thermal landscapes could be identified at the different stages of urbanization． LST for various land use had obvious discrepancies，the mean LST for the land use types was in a descending order of unused land，construction land，green land and water body． Different land use types had different thermal distribution at different stages of urbanization． The land use pattern influenced the urban thermal environment，especially the spatial distribution of green land and unused land affected LST more significantly
