The investigation shows that the microstructure of ZAC27 alloy evolves as follows: after 1 day ageing,α phase,η phase and ε phase appear in the alloy, moreover, the amount of α phase,η phase and ε phase increase with the increasing of ageing time; after 10 d ageing, the β phase decomposes and vanishes completely in the alloy; after 50 d ageing, phases gather and form the coarser equilibrium microstructure which consists of near equiaxed, shot club-shaped α,η and ε phase.

过饱和ZAC27合金时效1 d后，组织中出现了大量的η相、α相和少量的ε相。

This paper will present a new diode-clamp cascade multilevel converter derived from these two topologies. The novel concept of the new diode-clamp cascade converter is based on the connection of multiple three-level diode-clamp converter modules.The multilevel waveform is synthesized by adding of each converter output voltage.

The change of syconia number and the duration of phase B and phase D of different Ficus awkeotsang strains were compared. Results showed that the length of phase D of male syconia was about one month, while the length of phase B of female and male syconia was 2-3 months. This means that phase B and phase D could not overlap completely, resulting in the falling of syconia in phase B due to lack of wasps for pollination.

比较爱玉子不同品系雌、雄花序的B期与雄花序的D期花序数量变化及持续时间，结果表明：栽培爱玉子雄花序D期时长约1个月，而雌、雄花序的B期时长却是2~3个月，B、D期不能完全重叠，导致B期花序因没有小蜂传粉而脱落。

In order to eliminate the influence caused by the nonminimum phase characteristic of a common Boost DC／DC converter, Viswanathan K has proposed a novel tristate Boost DC／DC converter. For enhancing performance, the statespace averaging model of this converter was first presented in this paper. Due to the nonlinear nature in this model, an inputoutput feedback linearization technique was adopted, and a complete controllable linear system was obtained. Then a statefeedback control strategy was designed based on this linear system. Simulation results show that the proposed control strategy can assure constant output voltage in a wide range, so as to realize the stability of the system during large fluctuation of power supply and load disturbance. Good dynamic performance can also be achieved.
