Resin composition of good long-run workability comprising ethylene-vinyl alcohol copolymer

Disclosed are a resin composition comprising an ethylene-vinyl alcohol copolymer and a multi-layered structure comprising the resin composition. The resin composition comprises an ethylene-vinyl alcohol copolymer, and is characterized in that, when it is heated in a nitrogen atmosphere at 220° C., its MFR (at 230° C. under a load of 10.9 kg) shows a minimum value within 10 hours after the start of heating it, and shows a maximum value (MFRmax) within 100 hours after showing its minimum value, that it contains from 0.05 to 4 μmols/g of a carboxylic acid (A), and that it satisfies the following formulae (1) and (2):
0.5≦MFRmax/MFR0≦45   (1)
0.1≦(a1)/(A)≦1.0   (2)
wherein MFRmax indicates the maximum value of MFR (at 230° C. under a load of 10.9 kg) of the resin composition heated in a nitrogen atmosphere at 220° C.; MFR0 indicates MFR (at 230° C under a load of 10.9 kg) of the resin composition not heated; (A) indicates the total content (μmol/g) of the carboxylic acid (A) and its salt in the resin composition; (a1) indicates the content (μmol/g) of a carboxylic acid (a1) having a molecular weight of at least 75 and its salt in the resin composition. The resin composition has good interlayer adhesiveness when fabricated into laminates, and its moldings are yellowed little and have good appearances with few fish eyes (gels or hard spots) and streaks. While molded in melt, the resin composition ensures good long-run workability not smelling so much, and when recycled, it is yellowed little.

Method for identifying and analyzing single-point failure mode of launch vehicle

The invention provides a method for identifying and analyzing a single-point failure mode of a launch vehicle. According to the method for identifying and analyzing the single-point failure mode of the launch vehicle, the severe degree is divided at system levels, the severe degree grade is fine divided in the identification and analysis process of a single-point failure, the division of the severe degree grade is more accurate, and necessary conditions are provided for accurate selection of an FTA top event. The single-point failure mode with the severe degree types being the type I and the type II and the occurrence possibility grades being the grade A, the grade B and the grade C is selected as the FTA top event, the causes of the launch vehicle single-point failure with a large influence on the consequence severe degree and high occurrence possibility are analyzed more deeply, the logical relationship and the interaction between all the causes are also fully analyzed, and effective input is provided for elimination and control of the single-point failure. According to the method for identifying and analyzing the single-point failure mode of the launch vehicle, the single-point failure is identified and controlled comprehensively through combination of the characteristics of FMEA and FTA, and the comprehensiveness and the effectiveness of the identification and the control of the single-point failure are guaranteed.
