查询词典 radiation energy

The energy loss through feces was 0.077C (C: food consumption, KJ/d) and the energy loss through excretion was 0.052C at maximum feeding rate. In that the ratios of F and U to C were low in fish energy budget equation (Cui et al., 1997), the energy loss through feces at optimum feeding rate could be estimated by 0.077C〓(C〓: the optimum feeding rate) and the energy loss through excretion at optimum feeding rate could be estimated by 0.052C〓.

Then the error sources of the reaction type and electron type electric energy mete were analyzed and the theory analysis result through the concrete test have been proved. At last, the main conclusion has been drawn. When the induction type electric energy meter measures harmonics energy, the negative error characteristic appears. The higher the frequency of harmonics is, the greater the error is. The electron type electric energy meter can measure harmonics energy accurately in general cases. Except thermo-electrical conversion type electron type power meter, reaction type and electron type electric energy meter can measure direct current power.

The results show that the torsion energy and van der Waals interaction energy are the main types of energy and the substitution group has a great effect on the total energy of molecular. The aliphatic substitution would lead to the increase of total energy, while the aromatic substitution would lead to the decrease of total energy. The calculated results of bond length show that the bond length of aliphatic C—C is longer than that of aromatic C—C, which indicates that the rupture of aliphatic C—C is easier than that of aromatic C—C on heating.

The dose enhancement effects and decreasing effects caused by material inhomogeneity were studied quantitatively with a parameter named Dose Perturbation Factor, which was the ratio of the dose at a point in the heterogeneous phantom to the dose of the same spatial location point in the homogeneous phantom. It was showed that the degrees of the dose enhancement or decreasing depended on the energy of radiation, field sizes of the beamlets and compositions of the media. The dose perturbation for high energy X rays is greater than that for low energy X rays. At the same energy condition, the dose perturbation decreased when the field size increased. And the relationship between them was not linear.
