1.Abstract: By using the principle of the reliability optimum design,combining general calcu lation method,the article analyzed the reliability opgimum calculation method of the over surplus quantity of the hydraulic pressure sheath screw propeller,and validated its correctness through example.
2.This paper has analyzed the characters of sub-cooled refrigeration cycle and introduced the influence on refrigerating effect, power consumption and coefficient of performance (COP) by sub-cooling degree of some refriger- ants (R22、R134a、R407C、R410A). It also presents the relational expression between sub-cooling degree and performance parameters.
4.The results indicate that the field control cone is im portant in design of insulation structure of the terminals and joints of flexibl e cable. The elastic and permanent distortion of EPR used as main insulating mat erial should be 50% and 2% respectively. The surplus tolerance of sizes between XLPE and EPR should be 1.7～2.6.
6.Recrystallization and abnormal growth are also found in overpowered bonds.
7.Internal defects:lack of penetration,lack of fusion,slag,gas pole,carck,overheating.
8.A.S.M.E rated*, CSA Listed. Self-closing T&P Relief Valves for Water Heaters up to 100,000 BTU/Hr.
9.structure design:overall diameter of tire 990 mm,cross-sectional width of tire 198 mm,width of tread surface 188 mm,bead diameter at rim seat 612 mm (interference fit to rim),tread patterns variable angle and 29.5% saturation;
10.5[bbe] For this cause will a man go away from his father and mother, and be joined to his wife; and the two will become one flesh?
