Three methods and 3 calculating formula were used to choose for concrete operation according to the idea at urine iodine assayed with cerous sulfate reducing reaction by which WHO and ICCIDD draw up the preventive and curative criteria of iodine deficiency.

本文根据&WHO与ICCIDD制定的碘缺乏病防治标准与方法&中硫酸铈还原反应测定尿碘的意图，采用3种方法和3种计算公式对具体操作进行选择，并对原标准对照计算法的不合理以及计算误差对评价尿碘水平的效能进行了探讨。结果表明：（1）方法Ⅰ存在仪器误差，准确度不佳。方法Ⅱ线性关系和准确度较理想，但操作不便计算麻烦。方法Ⅲ线性关系和准确度与方法Ⅱ无差异，操作和计算简便、节约试剂。

Part oneObjective: To evaluate iodine nutrition status in ChongQing after the program of iodized salt supplementation by determining and analysing the urinary iodine of healthy subjects and patients with thyrocele and hyperthyroidism .

Methods The constructions of food, the varieties and amounts of food absorption in 3 consecutive days were investigated. Each 50 families respectively from town, rural area, fishery region and district producing salt were chosen as random stratified sample during off-and peak seasons for seafood. The averaging daily IAC of each crowd was calculated based on the statistical forms of food composition and iodine concentration in food reported previously. The results were analyzed with SPSS software and then compared with Recommended Dietary Allowance recommended by ICCIDD.

分层随机抽样调查，于海产品供应丰、淡两季，在海岛城、农、渔、盐区各抽50户家庭，调查膳食结构及每人连续3 d摄入的食物和数量，以《食物成分表》及以往报道的食物中的含碘量为依据，计算人均每天IAC，并与国际控制碘缺乏病理事会制定的每日碘的推荐供给量比较。

Nationwide sampling program is designed according to the resources distribution and coal-forming periods as well as coal rank and yield of coal in China, 305 coal samples were collected and determined by catalytic spectrophotometry combined with pyrohydrolysis.The geochemical mechanism of the concentration or depletion of iodine was discussed during the process of coalification,which including peat diagenesis and coal metamorphism.The contents of iodine in Chinese coals fall in the range of 0.04-39.51 mg/kg.

根据中国煤炭资源分布和成煤时代，兼顾煤的变质程度和煤炭产量分布，在全国范围内采集了305个煤样，采用高温热水解—催化分光光度法分析了煤中碘的含量，探讨了煤化作用(包括泥炭成岩作用和煤变质作用)过程中煤中碘富集或亏损的地球化学机制。

Iodine in the test solution was oxidized to IO-3 by excessive amounts of potassium permanganate solution and sodium hypochlorite solution,and excess of the oxidants was removed by reacting with sodium sulfite solution.
