found to increase with the cumulative dose of radiation, and a shift in the ferroelectric transition temperature(Tc) from 405 to 410 K was observed for25 k Gy. Upon irradiation, there is an enhancement......
, but the fiber broke with serious damage cracks. The cumulative AE energy was proportional to the polypropylene fiber reinforced concrete and mortar’s ductility. The damage mode and damage degree can be judged......
of 24.36 emu/g, and significant fluorescence. Furthermore, the cumulative in vitro release of the MFDDs exhibited controlled drug release. Cell viability experiments confirmed that the co......
the meniscus forms),which is composed of two factors,i e,water loss and cumulative pore size distribution (PSD),to provide a better explanation of the influence of superplasticizers(SPs) on early-age drying......
formed during laser cladding.Volume faction of multiple ceramic particles increases with the increasing of Y2 O3.The cumulative oxidation mass of the coating with 2 wt% Y2 O3 is decreased by one......
was studied. The effects of ore particle size, reaction temperature and the sum concentration of ammonium ion and ammonia on the leaching efficiency of zinc were examined. The leaching kinetics of low-grade..., sum ammonia concentration of 7.5 mol/L, the molar ratio of ammonium to ammonia being 2?1, and the ratio (g/mL) of solid to liquid being 1?10. Key words: NH3-NH4Cl-H2O system; low-grade zinc......
) calculation functions, has been newly developed. This system probabilistically evaluates the lifetime of boiler and turbine and quantitatively calculates the risk defined as the cumulative probability......
兼顾生态供给和人类需求的矿业城市生态安全格局构建--以湖北省大冶市为例陈勇1,2,肖晓1,刘艳中1,2,阮景华1,曾向阳1,2,王巧稚1,21. 武汉科技大学资源与环境工程学院2. 冶金矿产资源高效利用与造块湖北省重点实验室摘 要:构建生态安全格局是保障矿业城市可持续发展的重要手段.以大冶市为例,兼顾生态系统服务供给和人类需求,通过"源地-廊道"模式构建生态安全格局.针对全市人口的整体需求和部分人口的就近需求,将源地划分为全局型和局地型2种类型,分别采取直接拾取法和综合评价法进行识别,建立了以斑块需求强度,可达性表征人类需求强度,以斑块重要性,连通性表征生态供给能力的局地型源地识别模型.借助最小累积阻力模型(Minimum Cumulative Resistance,MCR)和目视判读方法,结合全局型......
and Armeen 12D) provided the required flotation selectivity, although this selectivity was lost in the case of pulp p H values outside the range between 2 and 4. Cumulative mineral recovery curves were......
. It was found that conventional linear cumulative damage rule failed in accurately evaluating the creep-fatigue life under stress controlled condition. The calculated creep damages by time fraction......
