The spin diffusion coefficient tensor of the A1-phase of superfluid 3 He at low temperatures and melting pressure is calculated using the Boltzmann equation approach and Pfitzner procedure. Then considering Bogoliubov-normal interaction, we show that the total spin diffusion is proportional to 1/T2, the spin diffusion coefficient of superfluid component [Formula: see text] is proportional to T-2, and the spin diffusion coefficient of super-fluid component [Formula: see text] is independent of temperature. Furthermore, it is seen that superfluid components play an important role in spin diffusion of the A1-phase.

Melting Pressure

The melting pressure and the specific volume of human blood was measured up to pressures of 1000 bar or more. The melting pressure curve has a slope of -138 bar K-1. The compressibility of blood is nearly twice the value of blood scrum. After application of high pressure the blood exhibits some haemolysis most probably due to the effect of the steel surface of the autoclave.

According to the problem of the joint performance degradation in melting nitinol alloy wire connection, the method of melting-pressure connection applying plasma arc welding as melting heat source was designed and the special flexible fixture was invented to realize the welding process. the Φ2mm nitinol alloy wire connected by this method is shaped well . The characteristic of the welded joint microcosmic formation shows that the grains appear rheological pattern in heat-affected zone. The tensile strength of the joint by plasma arc melting-pressure welding after annealing is 89% of the base metal, it also increases by 43% comparing with the plasma fusion welding joint. The shape memory of the joint is about 97.1% of the base metal, which is higher than the fusion weld joints by 3.3% .
