全光纤电光主动调Q激光器

利用马赫曾德尔Mach-Zehnder (M-Z)结构的尾纤型铌酸锂(LiNbO3)电光强度调制器作为Q开关元件,采用974nm半导体激光器作为泵浦源,峰值吸收系数为110dB/m的掺杂铒纤作为增益介质,实现了1550nm波长的全光纤主动调Q激光器。通过电光强度调制器对腔内损耗进行周期性调制,实现Q开关作用,获得了稳定的调Q脉冲输出。实验中通过改变泵浦功率和调制频率,研究了脉冲宽度和峰值功率的变化规律。获得输出脉冲重复频率50Hz-88kHz可调,重复频率1kHz时获得最窄脉冲宽度246ns,峰值功率近5W。

Application of adult attachment theory to group member transference and the group therapy process.

Although clinical researchers have applied attachment theory to client conceptualization and treatment in individual therapy, few researchers have applied this theory to group therapy. The purpose of this article is to begin to apply theory and research on adult dyadic and group attachment styles to our understanding of group dynamics and processes in adult therapy groups. In particular, we set forth theoretical propositions on how group members’ attachment styles affect relationships within the group. Specifically, this article offers some predictions on how identifying group member dyadic and group attachment styles could help leaders predict member transference within the therapy group. Implications of group member attachment for the selection and composition of a group and the different group stages are discussed. Recommendations for group clinicians and researchers are offered.

Further study on counter-intuitive response of single-degree-of-freedom structures

An energy method was proposed in Li et al. (2008), Int J Impact Eng 35(8):784-94 to determine the counter-intuitive region of the breathing mode response of plane-stress rings, which has different mechanism from the counter-intuitive phenomena observed in beams and plates. This paper extended the energy method for plane-stress rings to plane-strain rings and spherical shells for the determination of the counter-intuitive regions of the breathing mode response. Numerical simulations are conducted to support the predictions based on the energy method.     

Mechanism of simultaneous tripping of ground directional relays in a 6.6‐kV distribution system

In Kyushu Electric Power's 6.6‐kV distribution system, after a single‐phase ground fault occurred in the circuit of a distribution line, we experienced a phenomenon in which the analogue ground directional relays of the other circuits linked to the same bank were simultaneously tripped. In this paper, focus is placed on the mechanism and possibility of simultaneous tripping of ground directional relays. This mechanism was examined in an experiment carried out using an analogue simulator. The results of the test revealed that such simultaneous tripping was attributable to the neutral instability phenomenon of grounding potential transformers installed in an isolated neutral system. © 2010 Wiley Periodicals, Inc.
