The government has proposed to increase the stockpile of antiviral for dealing with a possible influenza pandemic from 3 . 7 million capsules to more than 20 million in phases as an integral part of the preparedness plan for influenza pandemic with particular reference to avian influenza 政府建议把抗病毒药物的储备量分批由三百七十万粒增加至超过二千万粒，作为流感大流行（特别是针对禽流感）应变计划的一部分，以应付可能出现的流感大流行。
According to the principle of the interaction between the beam and the cwr ( continuously welded rails ) that the longitudinal forces of cwr on railway bridges are passed on to the piers by the span structures of the bridge , the intensity of piers is checked up by calculating and the safety reservation is analyzed so that the design of the cwr on railway bridges is optimized and is safer and more economic 摘要根据梁、轨相互作用原理（桥上无缝线路的纵向力通过桥跨结构传递到桥梁的墩台上， ）检算桥墩的强度，进行安全储备量分析，进而优化新建桥上无缝线路设计，使设计既安全又经济。
From the influence of the state of the land demand to the industrial policies and urban economy in shanghai , this paper analyses the relationship among the land demand , land banking . and land supply , and makes research about the trend of the business land by the bp nerve network model , forecasts the total quantities of the land demand from now to 2010 , and sets forth the suitable quantity of the land banking during the 10th and 11th five - year plans in shanghai 摘要在分析上海产业政策和区域经济发展对用地需求的基础上，通过对土地需求、土地储备与土地供应的关联分析，建立了基于bp神经网络的预测模型，研究了上海经营性用地需求趋势的分析和对具体指标的细化分析，进一步地得出土地需求总量，提出了至2010年上海经济发展对土地需求的预测分析，以合理确定土地储备量。
On the basis of analysis of vibration and noise characteristics , measures for controlling noise and vibration in high - speed ship were described in this paper . frequency storage of different precision calculated by different method was also put forward . in dealing with the fluid in the tank , which affects the vibration of bottom plates in the ship , new regulations given in the paper are in better accordance with practical circumstance 在分析了高速船振动、噪声特性的基础上，阐述了适合高速船的振动与噪声控制措施，提出了相应不同计算方法精度的不同频率储备量，对处理舱内液体对船底结构振动的响应提出了更符合实际情况的新规定
There are too many problems in raw material supplying , such as , too many sources and types , complex constituent , variation price , large amount of needing , occupied funds , and safe inventory needed , et al . raw material assurance system is established under these circumstances . the main research of this thesis concentrates on the following parts : some optimization algorithms , raw material purchase , raw material inventory and real time early alarm of raw material purchase 在有色冶炼企业的原料供应工作中存在着这样的一些问题：原料来源多；品种多；成分复杂；价格不一；连续生产，对于原料的需要量大；原料采购资金占企业流动资金的比例大，一般达到了80以上；保证连续生产，需要有一定的原料储备量；原料采购策略与企业生产的产品市场价格信息脱钩等。
On the grain - production aspect , there exist three kinds of levels of productive potentialities of natural output , economic output and ecological output ; in the field of grain circulation , there exist three kinds of material flow movement forms of grain yield fluctuating , grain imports and exports fluctuating and grain storage fluctuating ; in the field of grain consume , there exist three kinds of levels of primary demand , the well - to - do demand and the well - off demand 全面粮食安全观，是指粮食生产可持续发展、粮食流通顺畅稳定、粮食消费公平与适度增长的一种粮食安全观。在粮食生产层面，粮食生产潜力具有自然产量、经济产量与生态产量三种水平；在粮食流通领域，存在粮食产量波动、粮食进出口波动与粮食储备量波动等三种物流运动形式；粮食消费表现为基本需求、小康需求与富裕需求等不同层次。
