Theory analysis and experiments have been done to find out the factors which decide on the self-restoration speed of low remanence toroid cores. The results show that in the right working circuit, the core with appropriate pulse permeability can be restored to its remanence after excitation within 1 μs without reset current. Therefore, the toroid core restoration in a MHz repeat frequency, multi-pulse induction cavity is likely to be solved by choosing the right material of cores and use proper working circuit.

The leaching reaction kinetics of weathered crust elution-deposited rare earth with mixed ammonium salts was studied. The influence of concentration of reagents and particle size of ore on leaching rate was investigated. The results showed that the diffusion process and leaching rate could be improved by increasing reagents concentration and decreasing leaching flowing rate and particle size. The leaching process could be explained with the shrinking core model, which could be controlled by the diffusion rate of reacting reagents in porous solid layer. The leaching rate obeyed the equation as 1-2/3η-(1-η)^{2/3}=7.126×10^{-4}C^{0.3038}R^{0.1942}t.

In this paper, surface potential decay after corona charge deposition has been investigated for low density polyethylene (LDPE) films. We believe that the three ways of electron charge decay on the surface of insulating polyethylene film is reasonable. The factor of neutralizing with opposite charge in air is negligible, and leakage along insulator surface or through the body is much more important for electron charge decay. Both ways are related with surface voltage of the sample. When the voltage is lower than a critical value, surface leakage contributes most. If the voltage is higher than this value, the electron energy on the surface of the sample exceeds the critical value and it is easy to cross the "deep trap". In this situation, the body leakage is more important, and the decay on the surface of sample speeds. That is why there exists decay curve crossing phenomenon.

The structural stabilities, elastic properties and charge transfers of EuX (X = O, S, Se, Te) compounds as a function of pressure are investigated extensively using first-principles calculations. The ground-state parameters, such as lattice constants, bulk modulus are predicted and compared with the available data, our results are satisfactory. The calculated phase transition pressures from the NaCl-type (B1) structure to the CsCl-type (B2) structure for EuX (X = O, S, Se, Te) also accord with the experiments. Particularly, the elastic constants of EuX (X = O, S, Se, Te) under zero pressure and high pressure are simulated appropriately for the first time via density functional theory. The softening behaviors of the elastic shear modulus C_{44} under pressure for the B1 phase of EuX (X = O, S, Se, Te) are captured, which should be responsible for the pressure-induced structural phase transition in the EuX system. It is also suggested that the softening behavior might be induced partly by the p → d and f → d electron transfers of Eu atom under pressure. In addition, the aggregate elastic modulus (B, G, E), Poisson's ratio (σ), Debye temperature Θp_{D} are also successfully obtained for both B1 and B2 phases of EuX.

By colchicine treatment of hybrids between Triticum turgidum and Aegilops tauschii (as seedlings), a fertile wheat plant (SHW-L2) carrying 56 chromosomes was artificially synthesized. At metaphase I of 50 pollen mother cells, the 56 chromosomes of the new wheat SHW-L2 showed a mean pairing configuration of 2.82 univalents, 6.18 rod bivalents, 19.39 ring bivalents, 0.5 trivalents, and 0.14 quadrivalents. Cytological analyses suggested that SHW-L2 had additional 7 pairs of chromosomes from the A and D genome besides the 42 chromosomes of common wheat. The special chromosome constitution of SHW-L2 may be derived from the chromosome doubling by the colchicine treatment of seedlings and then spontaneous doubling of gametes.

Some research has been done on making the compact, portable pulse forming line. A kind of ceramic and a kind of newly developed composite polymer are both used as the dielectric of the planar pulse forming line. The ceramic's dielectric constant ranges from 200 to 600 and the composite polymer's dielectric constant ranges from 100 to 200. It is easier to manufacture the large composite polymer dielectric bulks than to manufacture the ceramic bulks. In the experiments, using the large composite polymer bulk as the dielectric, the planar Blumlein line generated the pulse up to 100 kV with duration 90 ns. Using the ceramic bulk as the dielectric, the planar line generated the voltage pulse up to 60 kV with duration 92 ns.
