And nickel nitrate was added to largely increase the cineration temperature during the process and eliminate the inter-ferenee of phosphorus in sample matrix. 添加硝酸镍大大提高了石墨炉工作程序中的灰化温度,消除了样品基体中磷的干扰。
The forth chapter analyzes image pretreatment in three aspects: noise removing, cineration and restoration, and discusses deeply on the restoration algorithm of blurred images induced by relative motion. 第四章对图像预处理中的除噪、灰化、图像复原三个方面进行了阐述,特别是对由运动引起的模糊图像的复原算法进行了深入的探讨。
Trace lead in baked food is determined by air-acetylene flame atomic absorption spectrometry ( FAAS) with APDC-DDTC-MIBK as the extraction and preconcentration system after cineration process. 烘焙食品试样经灰化处理后,用APDCDDTCMIBK体系萃取富集试液中的铅,利用空气乙炔火焰原子吸收法测定烘焙食品样品中铅的含量。
Tobacco samples were handled by dry cineration, wet cineration and microwave digestion and then content of K, Ca, Mg, Cu and Zn from them were determined by atom adsorption spectrum. 采用干灰化法、湿法灰化、微波消解3种不同的样品前处理方法处理同一烟草样品,用火焰原子吸收光谱法测定K、Ca、Mg、Cu、Zn元素含量。
After the cineration of the peanut, the cadmium in it is extracted via the APDC-DDTC-MIBK system, and the content of cadmium is then tested via air-acetylene flame atomic absorption spectrometry ( FAAS). 花生米经灰化处理后,用APDCDDTCMIBK体系萃取富集试液中的镉,用空气乙炔火焰原子吸收法测定其含量。
The main advantage of this method is that the tobacco powder can be directly injected as suspended sample, and has no need for cineration in advance. 该方法最突出的优点是烟草样品不需灰化处理,烟草样品粉末与悬浮剂作用直接进样测试,节约了前处理时间和试剂。
On the dry removal of HCl in waste cineration 垃圾焚烧烟气中氯化氢的干法去除研究
〔 Methods 〕 PdCl 2 was used as a matrix modifier to find the best condition by improving the cineration temperature and reducing the interference of gas phase in atomization stage. 〔方法〕采用氯化钯作基体改进剂,提高灰化温度,减少原子化阶段的气相干扰,试验找出最佳测定条件。
At present in China the main processing methods to dispose the tannery sludge involve landfill, cineration and compost. However, there are lots of problems in existence for these traditional methods. 目前我国制革污泥的处理处置方式主要以填埋、焚烧、堆肥为主,这些处理处置方式都存在着一系列问题。
The results indicated that the relatively standard deviations of determination for uranium and nitrate radical are less than 2%. The determination results by the method are consistent with the high temperature cineration for uranium and the digestion with sodium hydroxide for nitrate radical. 结果表明,该方法测定铀和硝酸根的相对标准偏差都小于2%,分析结果与高温灰化法测定铀及氢氧化钠浸煮法测定硝酸根的结果基本一致。
