A method combining HPLC, a post-column derivation device and a fluorescent detector was used to determine residues of ten carbamate pesticides （aldicarb sulfoxide, aldicarb sulfone, oxamyl, methomyl, 3-hydroxy carbofuran, aldicarb, propaxur, carbofuran, carbaryl and methiocarb） in 68 vegetable and 32 soil samples under four different cultivation systems （traditional kailyard, open field vegetable base, green house and paddy） were collected from a certain city in South Jiangsu.

本研究采用高效液相色谱-柱后衍生-荧光检测法分析了苏南某市4种不同种植方式下（传统菜地、露天蔬菜基地、大棚蔬菜基地和水稻田）68个蔬菜样品和32个土壤样品中10种N-甲基氨基甲酸酯类农药（涕灭威、涕灭威砜、涕灭威亚砜、杀线威、灭多威、残杀威、克百威、3-羟基克百威、甲萘威和灭虫威）的残留量，结果表明在蔬菜中检出的氨基甲酸酯农药残留水平多处于0.2～23μgkg^-1，土壤中为0.1～10μgkg^-1；土壤中3-羟基克百威和灭虫威全部检出，其最高检测浓度分别为10μgkg^-1和1.64μgkg^-1，其他农药仅有少数检出。

The widely-planted vegetable spinach and Lactuca sativa were selected as the research objects. Five different plots were chosen for each plant and five samples were selected in each plot by using plum-shaped arrangement method to form the mixed samples. The contents of Pb, Cd, Cu, Zn were determined and evaluated by single-factor pollution index method.

方法］以人们广泛种植的菠菜和油麦菜为研究对象，每种植物选取了5个地块，每个地块按照梅花形布点法，选取5个样品组成混合样品，测定其中的Pb、Cd、Cu、Zn含量并采用单因子污染指数法进行评价。

Originally is unification may hold three samples, may test librate and press machine, revolves the sample which the compaction machine, the Marshall meter obtains, as well as the scene takes the core, the plank test specimen.

In this paper, orthogonal tests were conducted to study cut-tomato preservation with short-time microwave treatment. It was found that the vacuum packaged cut-tomato only reached low temperature of pasteurization after short-time microwave treatment, but it could be preserved for a long time under normal atmospheric temperature. The optimal treatment parameters were determined. The parameters are solution contains 0.12%vitamin C and microwave treatment time is 54 s; The image processing of samples were carried out to get color histograms and corresponding color mean, and effects of the method were explained with certain value. Effects of package on tomato were analyzed; it was considered that cut-tomato would be packaged with lightproof package.

通过正交试验对切分西红柿进行了微波处理常温保鲜的试验研究，得出了真空包装的切分西红柿在微波短时处理后只达到巴氏杀菌的低温杀菌温度，却得到能长期贮存的品质优良的样品的结果；确定了这种方法的最佳处理参数，其最佳参数为0.12％维生素C处理时间为54 s；对样品进行图像处理，得到色彩直方图和色彩均值，用确切的数值说明保鲜方法的保鲜作用；分析包装对西红柿保鲜的影响作用，认为切分西红柿应采用避光包装保存。
