By investigating kuru, the editorialist writes, current uncertainties about the size of the vCJD epidemic and the number of infected individuals can begin to be narrowed."Any belief that vCJD incidence has peaked and that we are through the worst of this sinister disease must now be treated with extreme skepticism."Lancet 2006;

ABSTRACT Global carbon cycle is a very important issue in the study of global climate change. Forest ecosystem carbon cycle is one of the important part of global carbon cycle, but at the present time there are considerable uncertainties in the research of global carbon cycle, which also exist in forest ecosystems carbon cycle research, especially in the estimation of carbon storage of region forest ecosystems and CO〓 fluxes exchanging with other systems.

全球碳循环是全球气候变化研究的核心问题之一，森林生态系统碳循环是全球碳循环的重要组成部分，目前在全球碳循环的研究中还存在很大的不确定性，这种不确定性同样存在于森林生态系统碳循环的研究中，尤其表现在对区域森林生态系统碳库大小及其与大气CO〓交换通量的估计上。

On the basis of 414 soil profiles from 14 provinces, it was found that soil organic carbon, differing from soil inorganic carbon and other elements, has a trend of exponentially decreasing with depth. Integral analysis of exponential curve contrasting with the linear model affords the uncertainties of linear model and exponential model for carbon storage calculation. It was found that the integration of TOC with the linear model has errors between +20% to +100%, much higher than that of the exponential model (-10% to +20%).

在收集分析14个省市414条的土壤剖面数据的基础上，发现土壤有机碳的垂直分布与无机碳和其他元素不同，存在指数分布规律，运用面积积分运算方法发现利用直线模型计算土壤有机碳库的误差(+20％~+100％)远大于指数模型的误差(-10％~+20％)。

Based on analyzing uncertainties when determining indicators system of ecosystem health assessment, an indicators system and a model for the evaluation of urban river ecosystem health was proposed. The model could offer the feasible and reliable base of decision-making for the river environment management.(4) An integrated method for land suitability evaluation based on geographic information systems under uncertainty was proposed.

运用模糊层次分析法，建立基于不确定性的模糊层次综合评价模型，并将理论应用于长沙市河流生态系统，查明城市河流的健康状态，研究结果可丰富河流生态系统健康研究理论体系，弥补当前生态系统健康与修复研究中城市河流方面的缺乏，对退化城市河流生态系统的保护和恢复起到很好的指导作用。
