AT corporation strategy research

AT卫浴的前身是一家创立于1995年的小微民营企业，乘着中国改革开放的春风，经过二十多年快速发展扩张，AT卫浴成长为一家为TOTO、科勒等顶级卫浴品牌提供OEM产品的中型卫浴企业。但近年来受到人民币升值、人口红利减弱、原材料成本大幅上涨等因素的影响，AT卫浴的利润率大幅下滑，面临着生存困境的AT卫浴开始迈出了建设自主品牌的第一步。虽然它具有优异的生产管理基础，技术研发水平，但是由于进入国内市场的时间较迟，品牌知名度低，目前陷入于白热化的价格竞争之中。如何通过正确的战略定位，充分发挥AT卫浴自身的管理、技术优势，寻找一条从“红海”竞争中脱颖而出的新路，开拓一片“蓝海”，这是本文的主要研究目的。 ...Predecessor of AT Sanitary Ware was a small private enterprise founded in 1995.

TiN及TiSiN涂层在海水环境下的摩擦学行为研究

目的对比研究海水环境下Ti N及Ti Si N涂层与Al2O3对磨的摩擦磨损行为。方法采用多弧离子镀技术在316L不锈钢及单晶硅片上制备Ti N及Ti Si N涂层。利用场发射扫描电子显微镜(SEM)、X射线衍射仪(XRD)及X射线光电子能谱仪(XPS)分析了涂层的截面形貌及化学组织成分。选择纳米压痕仪测量了Ti N及Ti Si N涂层的硬度及弹性模量,使用UMT-3往复式摩擦试验机研究了人工模拟海水环境下Al2O3与Ti N及Ti Si N涂层对磨后的摩擦磨损行为,并采用扫描电镜(SEM)、电子能谱(EDS)及表面轮廓仪来深入分析了磨痕的摩擦磨损情况。结果研究表明,Ti N涂层的硬度为32.5 GPa,当Si元素掺入涂层以后,Ti Si N涂层的硬度提高到了37 GPa。同时,较之于Ti N涂层,Ti Si N涂层的腐蚀电流密度下降了一个数量级。在摩擦实验中,Ti N涂层的摩擦系数和磨损率分别为0.35和5.21×10-6 mm3/(N·m),而Ti Si N涂层的摩擦系数和磨损率均有明显下降,分别为0.24和1.96×10-6 mm3/(N·m)。结论 Si元素掺杂后能显著提高Ti N涂层在海水环境下的摩擦学性能,主要归因于结构的致密,硬度、韧性、抗腐蚀性的提高及润滑相的形成

Preliminary evaluation of 110 peach/nectarine varieties on the gummosis disease resistance in Zhejiang Province(110个桃/油桃品种资源在浙江的流胶病抗性初步评价)

This study aimed to screen highly resistant varieties by investigating field gummosis disease levels in 110 local peach/nectarine varieties and selected varieties of 4- to 7-year-old trees. Combined with pedigree analysis, the source of the gummosis disease resistant germplasms was traced. The results showed that there were significant differences in the levels of gummosis disease among different peach/nectarine varieties, and the resistance gradually decreased with the increase of tree age. Among the 80 varieties that showed relatively stable levels of gummosis disease, nine varieties showed high resistance, most of which were peach varieties, such as ‘Qiubaitao’ and ‘Nanshantiantao’; 40 varieties showed resistance, such as ‘Hakuri’ and ‘Yuanmeng’; 16 varieties showed moderate resistance, such as ‘Hujingmilu’ and ‘Jinxiu’; nine varieties were susceptible to the disease, such as ‘Feicheng Baili’ and ‘Kurakato Wase’; and six varieties showed high susceptibility, such as ‘Bailutao’ and ‘Huyou 278’. The peach varieties were generally more resistant than the nectarine varieties. According to the genetic pedigrees, some resistant and highly resistant varieties, which originated from the traditional Chinese local variety ‘Chinese Cling’, had a genetic relationship. This research provides a reference for the selection of resistant varieties in production, as well as for further genetic and breeding applications.(为筛选流胶病抗性较强的桃/油桃栽培品种和种质资源，以110个桃/油桃地方品种和选育品种为试验材料，调查4—7年生树的流胶病田间发病情况，并结合系谱分析，追溯流胶病抗性种质来源。结果显示，不同桃/油桃品种间流胶病等级差异明显，抗性随树龄增大而逐渐下降，80个品种的流胶病等级表现较稳定，其中：9个品种表现为高抗，多为桃品种，代表品种有‘秋白桃’‘南山甜桃’等；40个品种表现为抗病，代表品种有‘白丽’‘圆梦’等；16个品种表现为中抗，代表品种有‘湖景蜜露’‘锦绣’等；9个品种表现为感病，代表品种有‘肥城白里’‘仓方早生’等；6个品种表现为高感，代表品种有‘白露桃’‘沪油278’等。桃品种的抗病性总体优于油桃品种。根据品种遗传系谱分析发现，部分抗病及高抗品种间存在不同程度的亲缘关系，‘上海水蜜’是部分抗病及高抗品种的原始亲本。本研究结果可为生产上选择合适的抗病品种和后续的抗病遗传育种提供参考。

过滤、吸附及灭活病毒的纳米催化材料的快速筛选方法

本发明涉及催化材料，具体地说是一种过滤、吸附及灭活病毒的纳米催化材料的快速筛选方法，具体操作为：1)以100～1000个碱基的核酸分子片段作为探针，采用喷洒或浸泡的方式将核酸分子吸附于催化剂上，然后用不少于探针原液9倍的水进行洗脱，筛选出吸附能力强的、即吸附量为原液重量60％)以上的催化剂；2)将上述步骤选取的催化剂对目标病毒进行吸附、洗脱，对催化剂用水或生理盐水一次或多次洗脱，然后对洗脱液中的病毒进行传统的活性检测；筛选出对病毒的过滤、吸附及灭活作用好的、即吸附量为原液重量95％的催化剂。本发明首先以核酸分子作为探针，建立了对纳米催化材料吸附性能和抗水性能进行快速筛选和评价的方法。带填
