奇正消痛贴属OTC药品，而OTC药品的营销思维方式与处方药有很多不同，单从产品的构思本身讲就是一个复杂的市场策划行为。近年来奇正消痛贴的销售量稳步增长，在贴膏类产品市场中异军突起，创下了一个又一个的销售记录，其运作过程已成为决胜于终端的经营典范。本从产品的属性、品牌战略的实施以及销售渠道和终端的管理角度对奇正消痛贴的市场运作过程作一系统的分析。 相似文献

利用国际上标准的热堆和快堆技术参数, 对“开式热堆一次通过”、“闭式热堆循环”和“闭式热堆快堆混合循环” 3 种核燃料循环方式进行长期平衡的物质流计算, 得到不同战略下的天然铀需求、分离功需求、核电装机类型容量需求、核燃料需求、核废料处置需求等结果。通过对比, 得出“闭式热堆快堆混合循环”是3 种循环方式中核资源利用率最高、放射性核废料产出量最低的战略选择。 相似文献

A colorimetric assay utilizing the formation of gold nanoparticles was developed to detect tetracycline antibiotics in fluidic samples. Tetracycline antibiotics showed the capability of directly reducing aurate salts into atomic gold which form gold nanoparticles spontaneously under proper conditions. The resulted gold nanoparticles showed characteristic plasmon absorbance at 526 nm, which can be visualized by naked eyes or with a spectrophotometer. UV–vis absorbance of the resulted gold nanoparticles is correlated directly with the concentrations of tetracycline antibiotics in the solution, allowing for quantitative colorimetric detection of tetracycline antibiotics. Reaction conditions, such as pH, temperature, reaction time, and ionic strength were optimized. Sensitivity of the colorimetric assay can be enhanced by the addition of gold nanoparticle seeds, a LOD as low as 20 ng mL−1 can be achieved with the help of seed particles. The colorimetric assay showed minimum interference from ethanol, methanol, urea, glucose, and other antibiotics such as sulfonamides, amino glycosides etc. Validity of the method was also evaluated on urine samples spiked with tetracycline antibiotics. The method provides a broad spectrum detection method for rapid and sensitive detection of reductive substances such as tetracycline antibiotics in liquid and biological samples. 相似文献
