The results showed that the traditional performance did not change by adding 2 - 3 % granularity of rare - eath and the readiation specification was in the safe scale by producing 800 - 1000 negative irons per cm3 , the diameter of anti - bacterial circle to golden staphylococcus is 18 millimeter , the diameter of anti - bacterial circle to colon bacil lus is 22 millimeter , the purifying formaldehyde ratio comes to 65 . 3 percent and the purifying ammonia - gas ratio comes to 52 . 11 percent 结果表明：加入重量比为2 ? 3的稀土细粉后，新型环保保健涂料的常规性能指标不变；其放射性亦在安全指标范围内，可产生800 - 1000个负离子/ cm ~ 3 ，对金黄色葡萄球菌的抑菌圈直径为18mm ，对大肠杆菌的抑菌圈直径为22mm ，具有较好的抑菌作用。
The second one analyzes the condition of china food security . first , it points that the disequilibria of china food in demand and supply among regions has become main insurance factors of food security on the base of judging the condition of china food security which links of food demand and supply in every region 第二部分对中国粮食安全状况进行了实证分析，首先在结合安全指标对我粮食安全状况进行判断的基础上，指出中国粮食供求在区域间的不平衡已成为粮食安全的主要风险因素。
Finally , according to test freeway , the research system is modified and tested . the algorithm process of the safety level quantification of road design is finished , and the calculation result ? reeway segment ? safety index value - is offered . furthermore , contrast between calculation result and actual accident data is processed to make sure the program feasibility 最后，针对试验道路，具体应用本文中的研究系统，计算、得到了道路各点位的安全指标值，并对计算结果与道路的实际事故数据进行对比，验证了系统的可行性。
On the basis of investigations into the progressive yield process and the possible failure modes of rcc gravity dams , the quasi - elasticity design limit state of the ctrtical stability criterion is proposed and the real working state of the dams designed according to the ctriterion is discussed . a check formula using the material strength reducing factor as the safety index and a simplified formula similar to against sliding stability fromula are derived . finally , the corresponding design safety factors are given by using fem calculations with various influence parameters to be taken into account 本文在研究碾压混凝土重力坝渐进破坏过程和可能失稳方式的基础上，提出了以准弹性临界作为稳定临界准则的设计极限状态，分析了按该准则设计的大坝的实际工作状态，导出了以准弹性强度储备系数为设计安全指标的审查公式以及形式与抗剪断公式相同的简化公式，探讨了定量计算考虑各种因素影响的相应设计安全系数的合理取值，并与现行规范方法进行了比较
In the part of the standard and index system of grassland ecological security evaluation , the author introduces selected principle , founded methods , sources of evaluation criterion and the principle that structures the index system of grassland ecological security evaluation , designs the concept frame of grassland ecological security evaluation learning from that of driving force - psr , and structures the index system of hierarchical structure of grassland ecological security evaluation according to the characteristic of grassland ecosystem and social and economic development of grassland 最后对草原生态安全评价的原理做了探讨，介绍了相关的评价方法。在草原生态安全评价的标准与指标体系研究中，讨论了评价标准选取的原则、建立方法、来源以及草原生态安全指标体系构建的原则，依据草原生态系统以及牧区社会经济发展的特点，借鉴驱动力psr生态环境系统服务的概念框架设计了草原生态安全评价的概念框架，并构建了草原生态安全评价指标层次结构体系。
