Highly (100)-oriented LaNiO3(LNO) thin films were grown on Si, SiO2/Si, Pt/SiSiO2/Si, as well as glass substrates by rf magnetron sputtering deposition at substrate temperatures ranging from 150 to 500 °C. As-deposited LNO films are metallic; those prepared at substrate temperature ∼150–250 °C have a resistivity of 0.4–0.5 mΩ cm and can be used as the bottom electrode for the fabrication of integrated ferroelectric capacitors on Si. A subsequent deposition of sol-gel derived Pb(Zr0.53Ti0.47)O3 (PZT) thin film on the LNO-coated substrate was also found to have a significant (100)- and (001)-oriented texture. The ferroelectric capacitor fabricated from these films displays a good P–E hysteresis characteristic.

Based on the invariance of differential equations under infinitesimal transformations of group, Lie symmetries, exact invariants, perturbation to the symmetries and adiabatic invariants in form of non-Noether for a Lagrange system are presented. Firstly, the exact invariants of generalized Hojman type led directly by Lie symmetries for a Lagrange system without perturbations are given. Then, on the basis of the concepts of Lie symmetries and higher order adiabatic invariants of a mechanical system, the perturbation of Lie symmetries for the system with the action of small disturbance is investigated, the adiabatic invariants of generalized Hojman type for the system are directly obtained, the conditions for existence of the adiabatic invariants and their forms are proved. Finally an example is presented to illustrate these results.

Thermal analysis techniques were applied to investigate the reaction characteristics of a slow‐propagation tungsten type delay composition system by means of differential scanning calorimetry (DSC) and thermogravimetry (TG). The ingredients of the delay composition were tungsten, barium chromate, potassium perchlorate, diatomaceous earth, and Viton. A formula of delay composition with a weight percentage of W/BaCrO4/KClO4/D. E./Viton=27 : 54 : 11 : 6 : 2 has been used in a self‐destruction mechanism of fuse, which was set as the original formula. In the first place, the reaction heat and weight loss for different compositions without Viton were measured during the reaction. The influence of each ingredient of the formula on the reaction system was analyzed from these experimental results. Afterward Viton was added in the samples of experiment to measure and analyze the influence of Viton on the reaction system. Finally, 28 experimental formulas of delay composition were designed on the condition that the weight percentage of Viton was kept constant and the maximum variation of weight percentage of all the others was limited within 20%. The delay compositions of various formulas were granulated and then the variations of reaction characteristics were measured to analyze the influence of weight variation of each ingredient on reaction characteristics. The results of this study are very important and useful for improving the self‐destruction mechanism of fuse.
