Author was menstruated content of boron and researched the status of lack of Boron and researched relativity of its Influencing facto, the results showed that the average content of available boron in the yellow soil was 0.39±0.27 mg/kg, 80 percent of its was under 0.5mg/kg which was lack for boron and 17.44 percent of its was under 0.2mg/kg which was especially lack for boron; The distribute frequencies of available boron contents of yellow soils in Chongqing was dispersedly, its range of 0.07mg/kg to 1.99mg/kg. The diversity of different zoology area was distinct. The result of pertinence analyses showed that available boron contents had correlativity with the pH(r=0.181** n=281) and CEC(r=0.124** n=281 and It had correlativity with Organic matte When the content of organic matte is high; in addition, soil granule、clime was the Influencing factor of availability of boron in Yellow Soils in Chongqing.
笔者通过调查取样对重庆市黄壤硼的含量进行测定并分析了缺硼的程度,对其影响因素进行了相关性分析,研究结果表明:重庆市黄壤有效硼的平均含量为0.39±0.27mg/kg,其中近80%的土壤样品有效硼含量低于0.5mg/kg,属于低硼或缺硼土壤,还有17.44%的土壤样品有效硼含量低于0.2mg/kg,属于极度缺硼的土壤;而有效硼含量的分布频率比较分散,变幅较大,从0.07mg/kg~1.99mg/kg,变异系数达到69.41%,不同生态类型区土壤有效硼含量的差异十分明显;而相关性分析结果表明:土壤有效硼与土壤pH值(r=0.181** n=281)和CEC(r=0.124** n=281呈正相关,在有机质含量较高的条件下与其相关性也较为显著(r=0.347** n=90,而土壤质地以及气候也对重庆市黄壤硼的有效性有很大的影响

The method on trans fatty acids analysis in food is very important. The effects of methylate sodium, potassium hydroxide, sulfuric acid and boron trifluoride in methanol and their different concentration and dosage on TFA analysis were studied. The chromatographic condition and the influence of time and temperature on the esterifation of TFA using boron trifluoride in methanol were optimized. A method for analyzing TFA were established by GC based on boron trifluoride in methanol and RT-2560(100m×0.25mm×0.2μm) capillary column.
研究了甲醇钠-甲醇、氢氧化钾-甲醇、浓硫酸-甲醇和三氟化硼-甲醇4种甲酯化试剂的浓度、用量及甲酯化时间和温度对反式脂肪酸检测的影响,优化了色谱条件,建立了以三氟化硼-甲醇法甲酯化,RT-2560(100m×0.25mm×0.2μm)毛细管柱为基础的反式脂肪酸气相色谱检测方法,C18:1-9 t, C18:1-11 t, C18:2-9 t, 12 t和C22:1-13 t 4种反式脂肪酸的最小检出浓度在0.774.08 mg/kg之间。4种反式脂肪酸不同添标浓度回收率为98.44%101.23%,重复测定的相对标准差在0.22%1.31%之间,有较好的准确度和重现性。
