We herein proposed a sample introduction technique based on solution cathode glow discharge(SCGD)of a portable design for inductively coupled plasma-optical emission spectrometry(ICP-OES)and its ap-plication in sensitive determination of *** products from SCGD containing mercury vapor,were transported by an Ar flow to ICP spectrometer for detection.A gas liquid separator(GLS)and a dryer were used to condense and remove most of the accompanying moisture,which greatly improved both the stability and sensitivity of the *** detection limit(DL)acquired by this developed method was 0.22μg/L(194.1 nm),which was nearly 82 times lower than that obtained by pneumatic nebuliza-tion(PN).The relative standard deviation(RSD)was 1.4%(n=14)for a 50μg/L *** solution(HNO_(3),pH 1)can effectively elute mercury *** accuracy and practicality were also demonstrated by the determination of GBW10029(fish)certified reference material,shrimp,crawfish,soil and human hair *** results showed good consistency with the certified values and the values obtained us-ing inductively coupled plasma−mass spectrometry.

The presentation method of the mechanical motion scheme must support thewhole process of conceptual design. To meet the requirement, a semantic network method is selectedto represent process level, action level, mechanism level and relationships among them. Computeraided motion cycle chart exploration can be realized by the representation and revision of timecoordination of mechanism actions and their effect on the design scheme. The uncertain reasoningtechnology based on semantic network is applied in the mechanism types selection of the needledriving mechanism of industrial sewing mechanism, and the application indicated it is correct,useful and advance.

作者： zou huijun(Shanghai Jiaotong University)Zhang Mingli(Shanghai Maritime University)

Dynamic equations of elastic linkage are formed by means of Kane equation and finitemethod. Eight main influential factors on the dynamic response of elastic linkage are considered inthese equations. Model error caused by the eight factors are investigated. Some useful conclusionsabout model error are derived from theoretical analysis and the numerical calculation of twenty-sixexamples.
