Structural integrity of the flywheel of reactor coolant pump is important for safe operation of a nuclear power plant. A shrink-fit multi-ring flywheel is designed with a fall-off function, i.e., it will separate from the shaft at a designed fall-off rotation speed, which is determined by the assembly process and the gravity. However, the two factors are ignored in the analytical method based on the Lame's equation. In this work, we conducted fall-off experiments to analyze the two factors and used the experimental data to verify the validity of the analytical method and the finite element method(FEM). The results show that FEM performs better than the analytical method in designing the falloff function of the flywheel, though FEM cannot successfully predict the strain variation with the rotational speed.

We investigate an all-solid-state continuous wave (cw) green (532nm), femtosecond near-infrared (823.1nm) and blue (402nm) laser system which is pumped by a diode-laser-pumped intracavity frequency-doubled and all-self-structuring cw Nd:YVO4/KTP 532nm green laser. The cavity parameters of the Nd:YVO4/KTP laser have been optimized and the maximum 5.6W TEM00 green laser is obtained at a 22W pump power with an optical-optical conversion efficiency of 25.5%. A Ti:Sapphire laser and nonlinear second-harmonic generation by a crystal BBO is used to obtain different wavelengths. A femtosecond laser with an average output power of 300mW at 823.1nm and 73mW at 402nm is obtained when the green pump power is 2.5W. The spectral full width at half maximum are 32.3nm and 5.1nm, which can sustain the pulses of 22fs and 33.3fs, respectively.

The interracial electron transfer （IET） dynamics of single CdSe core/multilayer shell （CdS2MLZnCdS1MLZnSIML） quantum dots （QDs） on the （110） surface of a futile TiO2 single crystal and TiO2 nanoparticles have been compared. The fluorescence decay rates of single QDs on TiO2 are faster than those on glass, an insulating substrate, due to lET from the QDs to TiO2. Whereas the average IET rates are similar for QDs on the single crystal and nanoparticles, the distribution of lET rates is much broader in the latter, indicating a broad distribution of QD adsorption sites on the TiO2 nanoparticles.

We study the ratchet model with both thermal and potential fluctuations, discussing analytically the coherence resonance of the particle moving in such a potential field. It is found that the correlation between the thermal and potential fluctuations has significant effect on the coherence of the system, i.e. negative correlation enhances the coherence of the system greatly, and with positive correlation, there appears the phenomenon that the coherence suppression and enhancement occur alternatively as the additive noise becomes larger.
