软夹硬力学不均匀焊接接头疲劳裂纹闭合行为的实验研究

力学性能不均匀是焊接接头的三大待征之一，本文采用柔度法研究了不同硬夹层宽度的软夹硬力学不均匀焊接接头疲劳裂纹的闭俣行为。研究结果表明，裂纹尖端附近软区的局部屈服在疲劳载荷卸载过程中促使裂纹闭合。随着硬夹层宽度的减小，这一影响越来越明显。

Development of a sensitive micro-magnetic chemiluminescence enzyme immunoassay for the determination of carcinoembryonic antigen

A micro-magnetic chemiluminescence (CL) enzyme immunoassay with high sensitivity, selectivity, and reproducibility was developed for the determination of the tumor marker, carcinoembryonic antigen (CEA) in human serum. A sandwich scheme assay has been utilized with fluorescein isothiocyanate antibody (FITC)-labeled anti-CEA antibody and alkaline phosphate (ALP)-labeled anti-CEA antibody being used in the CL detection. The CL signal produced by the emission of photons from 4-methoxy-4-(3-phosphate-phenyl)-spiro-(1,2-dioxetane-3,2′-adamantane) (AMPPD) was directly proportional to the amount of analyte present in a sample solution. The influences of the reaction time of antigen with antibody, the reaction time of substrate with label, the dilution ratio of ALP-labeled anti-CEA antibody, the concentration of FITC-labeled anti-CEA antibody, and other relevant variables upon the CL signal were examined and optimized. The CL responses depended linearly on the CEA concentration over the range from 2 to 162 ng mL⁻¹ in a logarithmic plot. Assay sensitivity as low as 0.69 ng mL⁻¹ was achieved. A coefficient of variance of less than 13% was obtained for intra- and inter-assay precision. This method has been successfully applied to the analysis of CEA in human serum. According to the procedure based on spiked standards, the recoveries obtained were 80–110%. Comparison experiments were carried out with the commercially available CEA chemiluminescence immunoassay. Satisfactory results were obtained according to a paired t-test method (t value < t _critical at the 95% confidence level).     

Use of Electrical Resistance to Detect the Formation and Decomposition of Methane Hydrate

The changes of electrical resistance(R)were studied experimentally in the process of CH_4 hydrate formation and decomposition,using temperature and pressure as the auxiliary detecting methods simultaneously.The experiment results show that R increases with hydrate formation and decreases with hydrate decompositon.R is more sensitive to hydrate formation and decompositon than temperature or pressure,which indicates that the detection of R will be an effective means for detecting natural gas hydrate(NGH)quantitatively.
