The eggs of A. punctulata have a high temperature coefficient in the resting state: Q10 = 4.1. On fertilization and on cytolysis the temperature coefficient falls to less than half the resting value: Q10 = 1.8 and 1.9 respectively. The factor by which oxygen consumption increases on fertilization is a variable, its magnitude depending on temperature as well as on egg species. It is nearly ten times greater at 11°C. and only double at 29.9°C. By extrapolating to 32°C. there would be no increase on fertilization. Critical thermal increments common to many oxidations, 6,500, 10,800, and 12,500, have been found. The possible significance of these results is discussed in relation to the catalytic mechanisms and structural organization of the egg cell.

Based on the fire tests of WILLIAMS double-poles structure, considering the dual nonlinear interaction of material and geometric, established one complete finite element model of grid structure. For the performance that the physical and mechanics properties of steel will degrade while the temperature arising, simulate the test models with ANSYS, get a better numerical results, proof the numerical method is feasible.

Nmr Study

Measurements of both the 51V and 195Pt Knight shift in the V3Pt compound are reported for temperatures ranging from 300 K to about 1300 K. The temperature coefficients of the Knight shift and the NMR linewidth have been determined. An interpretation of the observations is given in the frame of a model which is based on the temperature dependence of the core polarization contribution to the total Knight shift.
