Design and Implementation of Mobile Banking Based on WeChat Platform
微信是一个不断发展、创新的产品,并具备较大的用户群体。采用微信平台开展微信银行业务,为广大微信用户提供安全、可靠、体验性好的金融服务与生活服务,可提高用户业务办理的便捷性与高效性,同时也有利于银行的营销与运营。现今为止,已有多家银行对“微信银行系统”进行开发与应用。然而,由于微信银行是依赖于微信而得以推广的,因此每当微信发布新的接口API时,微信银行系统就要进行大量的改造甚至是重构以满足新的接口规范的要求。这将带来巨大的工作量以及高额的成本。同时,业务功能开发测试时间较长,难以满足业务需求。 本设计通过分析各家银行的微信公众账号应用的主要功能,并结合了微信的API接口规范和银行的业务特征,从...WeChat which is featured by its continuous development and tremendous innovation, has boasted a large group of users. Using WeChat bank platform for the general WeChat users with safe, reliable, good experience sexual services, financial services and life can improve the user convenience and efficiency in the business to deal with, as well as to marketing and operations of the bank.

On The Contract Of Public - Private Partnership (PPP)——As The Center with The Project Contract
PPP模式中,政府部门与社会资本之间存在利益冲突,合同是调整这些利益冲突的重要方式。PPP合同体系表现为一系列形态各异的合同,这其中最为主要的合同形式是PPP项目合同。PPP项目合同在我国的PPP实践中存在合同定性模糊、合同风险不明确以及合同争议解决方式不明确等问题。而通过构建一套标准化的项目合同文本是解决这些问题的关键,在构建标准化合同中需要甄别强制性规范和任意性规范的范围。厘清这两种规范的存在范围是进行合同标准化设计的基础和前提。文章通过四个部分进行论述。 第一部分是关于ppp模式关系利益协调合同理论。政府在和社会资本合作中存在利益冲突,通过构建PPP合同体系是解决这些利益冲突的重要工具...In the PPP mode, there are always existing interest conflictions between the government apartment and the private apartment. The contract is the main method to adjust these interest conflictions. There are different form of contract in the PPP contract system, the PPP project contract is the main form. There are some problems in our country’s PPP practice, including that: the ambiguity of the lega...学位:法律硕士院系专业:法学院_民商法学学号:X201112004

Methods: Forty-eight six-week SPF; female SD rats were randomly divided into blank control group and model; group. The model group received letrozole to induce PCOS model, then the; successful modeling rats undergone were divided into model control; group, melbine group and berberine group. During the treatment, 1%; carboxymethylcellulose was used on the blank control group and model; control group, 1% carboxymethylcellulose plus melbine were used on the; melbine group while 1% carboxymethylcellulose plus berberine were used; on the berberine group. The testosterone and fasting insulin of rats; were detected, the ovarian pathological slices of HE staining and the; StAR immunohistochemical pathological slices of rats were observed under; light microscopes. Results: In this experiment, the model rats have; typical PCOS manifestations: the ovary has polycystic changes; the; testosterone rises (P<0.05); the fasting insulin rises (P<0.01), which; indicate that insulin resistance exists. Both melbine and berberine can; improve the insulin resistance of model rats, but the performance of; berberine in lowering androgen is better than melbine. The testosterone; of PCOS hyperandrogenism is positively related to the StAR density on; the cytomembrane of theca cells. Conclusion: Berberine has effect on; PCOS. It can not only improve insulin resistance but also treat; hyperandrogenism by lowering the StAR density on the cytomembrane of; theca cells to decrease the testosterone.福建省漳州市自然科学基金项

The abundance and diversity of nanoplankton in Arcitic Ocean
近年来随着全球气候变化对北冰洋生态环境的影响日益显现,北极微型浮游生物生态学研究得到了广泛的重视和实质性的进展。对北冰洋微型浮游生物的主要类群:异养细菌、古菌、光合异养原核生物和微型真核生物的分布及其多样性研究进展做了概述,并在此基础上展望了未来北冰洋微型浮游生物学研究。Asthe most abundant and the most taxonomically and genetically diverse organisms in the marine ceosystem,nanoplankton predominate in the marine system concerning their bioactivity,biomass,and production.They play an important role in the carbon fixation process in the Arctic Ocean,and are an important component to regulate the biosphere.Furtherly,nanoplankton can be an important indicator of the changing environment,since the changes in the community,structure and biomass of nanoplankton reflect the changes in the pathways of nutrient and energy transferring in the food web and the changes in the biogeochemical cycle.Recently,ecology study of the Arctic nanoplankton has been paid more attention due to the increasing impacts of climate change on the Arctic marine ecosystems.Substantial progress has been achieved.The Arctic heterotrophic bacteria were reported to resemble those in the seas of lower altitudes in their high abundance and biomass with seasonal successions.Particle-associated bacteria often show a higher specific metabolic activity than the free-living communities.So far,there are few reports on the proteorhodopsin(PR)-containing bacteria.High diversity has been reported for this group in the Chukchi Sea,which can be attribute to yariable bacteria communities.A large number of aerobic anoxygenic phototrophic(AAP) bacteria have been found in the Chukchi Sea with a distinctly seasonal succession.The photosynthetic group in the Arctic Ocean was found to be mostly composed with the nanoplankton(≤20μm),described as a polar ecotype of the small prasinophyte Micromonas.The high correlation between the abundance of coccoid cynaobacteria and temperature results their low abundance at the high latitudes There are only a few studies of Synechococcus in the coastal Arctic Ocean.The Micromonas is proved to be ubiquitous throughout the Arctic Ocean,especially at the chlorophyll-maximum layer,and may be a major contributor to the primary production in the Arctic Ocean.Until now little is known about the distribution of heterotrophic nanoflagellates in the Arctic Ocean,compared with phytoplankton and prokaryotes.Many scientific questions,which deserve special attention,remain unsolved due to lack of continuous sampling and the complexity of the nanoplankton characteristics.Some of them have been highlighted here in the Arctic nanoplankton ecology.(1) More attention should be paid to the effect of the climate change on the nanoplankton community in the Arctic Ocean,considering its major and often dominant contribution to the total ecosystem.(2)Most of the investigations of nanoplankton community are focused on the Atlantic Arctic Ocean of the Arctic Ocean.It is necessary to investigate the community structure of the nanoplankton in the entire Arctic Ocean.(3) As a photoheterotrophic microbe,AAP bacteria may play a special role in the ecology in the Arctic Ocean.However,little is known about the distribution,abundance,and diversity of the AAP bacteria in Arctic Ocean.(4)Archaea seems to be of special significance in the Arctic waters with large population existing in the surface water.More work need to be done on their diversity and their functions in the energy flow.国家自然科学基金(40576002;41076130);国家海洋局青年基金项目(2010116
