The article analyzed the main resources of the uncertainty of the measurement, which include uncertainty of the working curve, uncertainty of the resolution ratio of the instrument, uncertainty of measure unrepeatability, uncertainty of standard solution, etc. It quantified these uncertainties respectively and composed them to a standard uncertainty. Finally it got the expanded uncertainty of the total organic carbon measurement.

分析了测量过程中不确定度的主要来源，即工作曲线的不确定度、测量仪器读数分辨率导致的不确定度、测量不重复性引起的不确定度、标准溶液引起的不确定度等，分别量化后合成标准不确定度，得到总有机碳测量的扩展不确定度。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
