求翻译：目前，我国没有用于检测剩余污泥中重金属的标准方法，拟对土壤中铬含量的检测方法（二苯碳酰二肼分光度法）和砷含量的检测方法（二乙基二硫代氨基甲酸银分光光度法）进行改良，用改良后的方法检测兰州市雁儿湾污水处理厂高温厌氧消化后的剩余污泥中铬含量和砷含量。是什么意思？

At present, there is no standard method for the detection of residual sludge of heavy metals, the proposed detection method on soil chromium content (diphenyl hydrazine Spectrophotometry) and arsenic content of the detection method (diethyl dithiocarbamate formic acid silver spectrophotometry) impro

At present, our country is not designed to detect heavy metals in the sludge of a standard methodology in the soil, to be the way to detect chrome content direct carbon thionyl chloride (2 2 live-ACT) and light the way to detect arsenic (2B, 2 sulfur amino-formic acid generation silver spectrophotom

At present, our country has not used in examining in the surplus sludge the heavy metal standard method, draws up the chromium content examination method (benzoin carbonyl two jing divides luminosity law) to the soil in and the arsenic content examination method (two ethyl dithio- amino silver forma

Currently, in China no for detection remaining sludge in the heavy metal of standard method, intended on soil in the chrome content of detection method (II benzene carbon n II hydrazine min photometric method) and arsenic content of detection method (II b base II sulfur generation amino formic acid
