After some of; of the glove when some committing the crime commits the crime, be in spot aspersion, benzine, lime, 666 pink or sweep the floor wait for a method, destroy cotton of the bag on socks of coat of shoe of footmark; some, foot, or change the shoe that wears other, the article that makes pretending; when the finish after some cases commits the crime, be used even with this and incendiary destroy the site, this gives collect in the round mark obtains evidence and undertake examining working bringing very great difficulty.

有的作案时带手套；有的作案后在现场洒水、汽油、石灰、六六六粉或扫地等方法，破坏足迹；有的鞋外套袜、脚上包棉花，或换穿他人的鞋，以此进行伪装；甚至有的案后毁掉作案时用的物品以及放火破坏现场，这就给全面采痕取证和进行检验工作带来很大困难。

Benzene hexachloride, dichlorodiphenyltrichoroethane and organophosphorus pesticides in 103 soil samples collected from Wutongqiao district of Sichuan were detected by gas chromatography. Spatial distribution characteristics of residual pesticide in soils of transitional zone from mountain to plain was evaluated by employing the methods of GIS and geostatistical techniques.

以四川省五通桥区为例，利用气相色谱法检测丘陵平原过渡区103个样点的土壤样品中六六六、滴滴涕和10种有机磷农药残留量，利用地统计方法和GIS技术，评价研究区域内的土壤农药残留空间分布特征。

Be cautious about the use of benzene hexachloride as an insecticide as a dust or spray against pea and bean weevil because it is very

六六六作为杀虫剂喷洒于豌豆，青豆类，毒杀象鼻虫，要慎用，因为它极易致癌。

Hazard analysis sheet is not updated and potential hazards are not identified in part of raw materials e.g. heavy metal, benzene hexachloride and DDT in raw materials, heavy metal and toluene diamine in inner packaging materials.

危害分析表中对部分原料的不同危害未明确识别，如原料鲜奶(化学危害：六六六/滴滴涕/黄曲霉毒素/重金属/四环素/磺胺类等)和内包材甲苯二胺/重金属

The content of heavy metal and pesticide in the aquatic product of Shenzhen market were investigated on June, 2002. The results showed that the contents of the pollutants were Hg: 0.005~0.221 mg/kg, As: ND~1.210 mg/kg, Pb: 0.4~1.6 mg/kg, Cd: ND~0.33 mg/kg, Cu: 0.1~6.4 mg/kg, Cr: 0.02~0.49 mg/kg, benzene hexachloride: ND~0.041 mg/kg and DDT: 0.002~0.022 mg/kg wet weight, respectively.

2002年6月对深圳市场水产品中的重金属和农药含量进行了调查，结果表明：深圳市场水产品（本研究中水产品均以湿重计算）中各污染物质量分数分别为Hg 0.005~0.221mg/kg，As未检出～1.210mg/kg，Pb 0.4~1.61mg/kg，Cd未检出～0.33mg/kg，Cu 0.1~6.4mg/kg，Cr 0.02~0.49mg/kg，六六六未检出～0.041mg/kg和DDT为0.002~0.022mg/kg。

In this study, dichlorodiphenyltrichloroethane, hexachlorocyclohexane and chlordane were measured in 23 aquatic organism samples collected from Deep Bay, South China. Results showed that, the concentrations of DDTs, HCHs and CHLs in fishes were in the range of 1.84~286.83, 0.08~1.85 and 0.45~118.81ngg^(-1), respectively.

为了更好地理解深圳湾有机氯农药的污染现状及其生物累积规律，于2004年2月采集了该海域23个鱼类、虾类、蟹类生物样品，分析了其体内滴滴涕、六六六和氯丹各组分的含量，并对其人体健康风险进行了初步评价。

If operate as per production regulation,qualified non-polluted agricultural products can be produced.4 The detection rate of r-BHC in the grain is 24.0%,which is within the range of standard,other BHC isomers are not detected;No BHC in vegetables;No DDT in grain and vegetables;The total detection rate of 4 types of organic phosphor pesticides is 31% in the grain and vegetables,within which the content of dichlo rovinyldimethy 1 phosphate and dimethoate is a little bit higher than the standard,but the content of Baytex and Sunithion is lower than the staneard.5 The heavy metal detection rate in the grain and vegetables are stated respectively as following:Arsenic:none,none; Chrome:8%,72.4%; Lead:6%,13%;Cadmium:none,none; Hydrargyrum :none,none.

粮食中γ一六六六的检出率为24.0％，未出现超标现象，其他六六六异构体均未测出，蔬菜中六六六未检出，粮食和蔬菜的DDT未检出；粮食和蔬菜中的四种有机磷农药总检出率为31％，其中敌敌畏、乐果出现个别超标现象，倍硫磷和杀螟松未出现超标现象。 5、重金属在粮食和蔬菜中的检出率分别是：砷：未检出、未检出，铬：8％、72.4％铅字6％、13％，镉：未检出、未检出，汞：未检出、未检出。

At first, the concentration distribution of four main hexachlorocyclohexane distributing isomers in Xingang Harbour marine water and Haihe River estuarine water was investigated and for the first time, the ERs of α-HCH in the above two waters were studied.

首先，调研了天津新港港湾水和海河河口水中六六六主要异构体(α-、β-、γ-、δ-)的分布，并首次测定了以上两天然水体中α-六六六的ER值。

The stable carbon isotope values of α-,β-,and γ-hexachlorocyclohexane isomers were determined by GC-C-IRMS,EA-IRMS,and Dual-inlet IRMS in this study.

应用GC-C-IRMS技术分析了水样品中α-和γ-六六六的碳同位素组成，结果表明六六六在溶解、稀释、萃取、挥发等过程碳同位素组成没有分馏现象。

This method can be used to detect 16 pesticides in 30 minutes, including organophosphorus (parathion-methyl, phorate, isofenphos-methyl, malathion, chlorpyrifos, fenthion), organochlorine (dichlororos, heptachlor, chlorothalonil,α-hexachlorocyclohexane,γ-hexachlorocyclohexane,δ-hexachlorocyclohexane, p, p'-DDE, p, p'-DDD), pyrethroids and triadimefon in vegetables.

采用选择离子－气相色谱－质谱联用方式，依据保留时间和特征离子丰度比，可以在30 min之内检测有机磷（甲基对硫磷、甲拌磷、甲基异柳磷、马拉硫磷、毒死蜱、倍硫磷）、有机氯（敌敌畏、七氯、百菌清、α-六六六、γ-六六六、δ-六六六、p， p'-DDE、p， p'-DDD）、除虫菊酯、三唑酮等16种农药。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
