蚕种生产是一项技术性强,受控因素多的产业,同时又是一种有生命的特殊商品和生产资料,在生产、流通、消费过程中有其特殊的技术要求,因此,加强蚕种质量管理是提高蚕种质量必不可少的重要手段。建国以来蚕种生产上制定的蚕种生产技术要点和检验办法等,无疑对保证蚕种质量起到了积极作用。但不足之处是成品检验是事后把关,不能有效地控制在生产过程中出现的质量问题,从而制约蚕种质量的进一步提高并使生产和经营蒙受损失。在市场经济下,面对２１世纪又如何进行质量管理呢？现结合蚕种生产实际,谈一点在蚕种生产上推行全面质量管理的… 相似文献

自动化测控蚕种催青技术探讨 总被引：1，自引：1，他引：0
为了适应蚕桑生产发展和蚕桑科技进步的要求,改变原来蚕种催青室仅靠人工控制的落后局面,启东市蚕桑指导站自2002年8月起实施了蚕种催青室改造,引进安装了目前国内最先进的自动化测控系统,配备引进了国家专利产品镀锌铁质蚕种框架,配置了与自动化测控系统相适应的加温、补湿、感光、匀风等设施。2003年4月投入试运行,经过1年4期催青后,根据运行中发现的缺陷和问题,于2004年7月对引进系统的不适宜部分进行了完善改造,使整个系统运行质量达到同行业最优水平,探索出了一整套适应全新设备的蚕种催青技术,现将结果总结如下。1自动化测控蚕种催青… 相似文献

提高蚕种生产的机械化、自动化、智能化水平有利于降低蚕种生产成本和提升蚕种生产效率。针对目前蚕种生产过程手工切削种茧用工成本高、效率低等缺点,设计了一款能够完成种茧切削任务的自动化设备。结合不同家蚕品种的茧形特征,将蚕茧切口过程分为粘黏分离、排列运输、夹持、切削等步骤,设计出能够实现对应功能的零部件并组装制作出实体样机。用样机对来自不同家蚕品种的不同茧形及大小的蚕茧进行切削试验,结果表明:该设备对蚕茧之间的粘黏分离成功率为40%左右,排列输送成功率在75%以上,夹持成功率60%左右,切削成功率约50%;完成单粒蚕茧切口任务平均耗时15 s左右。该设备经进一步优化各个部件结构以及更换零部件制作材料后,有望应用于蚕种生产。 相似文献

When early people made their appearance, zoonotic infectious diseases were already waiting, but epidemic diseases did not appear in human history until people began to live in large numbers under conditions of close contact, mainly during the last 10,000 years. Disease has decimated urban populations, conquered armies, and disrupted society. The focus here is on (1) the plague of Athens and the Black Death; (2) smallpox, influenza, and rabies; (3) avian influenza prion diseases, and foot & mouth disease; and (4) emerging and re-emerging diseases. All have veterinary public health associations. In Athens, Greece, in 430 BC, when the Spartans ravaged the countryside, hordes crowded into Athens so that orderly movements, space in which to live, and adequate supplies of food became impossible. Crowding of any population fosters disease transmission; chaos and disorder enhance it all the more. Out of northern Egypt came a terrible plague from across the Mediterranean Sea. The identity of the plague of Athens remains unsure, but the well-considered conclusion is Rift Valley Fever, a mosquito borne, viral zoonosis. The Black Death, also called the Plague, raged in Asia for centuries. In 1347, the Black Death was brought by a ship out of Asia to Sicily. The scenes of devastation were repeated throughout Europe, with 90% or more of the people dying in city after city. Influenza, too, has been a cause of periodic human epidemics, but the great pandemic of influenza occurred in the last months of World War I. In the years of highest occurrence, more than half the world's population became clinically infected. If veterinary public health had been born earlier, it could have led to elucidating the epidemiology of influenza and the plagues of Athens, Europe, and Asia. In turn, smallpox had also caused continual tragedy. In 1796, Edward Jenner began to harvest pustules of cowpox from children or infected cows and inject them into susceptible children. In 1980, the World Health Organization declared that smallpox had been eliminated from the world. Rabies, though, still strikes terror. A number of animal diseases, broadly termed emerging and re-emerging diseases, need surveillance because they have the potential to impact human health. From late in 2003 to 2007, the highly pathogenic H5N1 influenza virus in poultry infected at least 121 people and caused 62 deaths in four countries. The prion diseases, too, all have very high numbers in concentrated contacts. To control these diseases, veterinary public health is essential, with diagnosis, epidemiological surveillance, clinical manifestations, and prevention as primary measures. 相似文献

On 26th of july 2007 a new case of bluetongue was notified in the Netherlands and on 2nd of august 2007 foot-and-mouth disease was diagnosed in Surrey, England, which raised the threat of having both infections simultaniously in one area. Bluetongue and foot-and-mouth disease have a different pathogenesis, but symptoms may resemble each other at a later stage of infection. The pathogenesis and possible clinical symptoms of both infections are discussed and illustrated with pictures. 相似文献
