英语翻译
9.Fossil fuel use.The contribution in this impact category is calculated using :
where Ni is the increase in energy input requirements per unit of consumption of fuel I and Fi is the consumption of fuel i per unit of product.The contribution in this impact category is measured in MJ of surplus energy per MJ of extracted energy in the process.
10.Land use.TRACI uses the density of threatened and endangered (T&E) species in a specific area as a proxy for environmental importance of land.It relates the location to be modified with the T&E species database to calculate the potential T&E displacement at that site.The contribution in this category is calculated using:
where Ai is the human activity per functional unit of the product,T&Ei is the T&E species count for the county and CAi is the area of the county under consideration.
11.Water use.This impact category ofTRACI analysis is designed to capture the significant
use of water in areas of low availability.It uses the total amount of water being used in terms of its mass or volume and accordingly using the corresponding characterization value to calculate the impact.The contribution in this impact category is measured in gallons.
TRACI has been developed to provide the most up-to-date possible treatment of impact categories for North America.It provides the provision of selecting the region (within US) where each process in the various life cycle phases of a product/service takes place.This helps in providing a more comprehensive customized environmental analysis for a process/service as it takes into account the current environmental health of that region and the consequent impacts of various stressors on it.

9.化石燃料的使用.化石燃料对（...这个您根据文章主旨填个词吧,这里没写出来,我也不好乱写）的影响是按照如下方法计算的：其中Ni是没小号一个单位的I（这是个名字?）化石燃料对能源投入需求的增加值,Fi是每单位产品需要的燃料i的数量；这种影响的贡献是通过（生产?）过程中萃取的每兆焦（MJ）能量所能带来的富余能量值来衡量的
10.土地使用.TRACI使用某一特定区域的濒危物种密度作为该块土地生态重要性的衡量指标.该方法用濒危物种数据库的相关信息来修正研究地块的数据,来计算潜在的物种消亡.这一类别的贡献是通过如下方法计算的：
Ai表示该产品每有效单位的人类活动；T&Ei表示该地区的濒危物种数目,CAi表示被考察地区的地域面积
11.水的使用.本类别的TRACI分析被设计来获得缺水地区的水资源使用重要性.它使用该地区所使用的总水量体积或者相应的特征值来计算影响.该分类的计算以加仑为单位.
TRACI被发展以提供最新的南非影响类别的处理方式.它提供（在美境内）选择区域的原则,这些地区是能够展示产品/服务的各种生命周期阶段的.这可以帮助提供针对过程/服务的更全面环境分析,包括所研究地区的当前环境健康情况及受各种压力因素影响后的情况.
