This paper presents a new algorithm FTGP which could deal with temporal information in Flexible planning framework. The new algorithm could solve the action whose duration is no longer an abstract time unit, but a positive real number. We defined new mutex relationships according to the characters of temporal planning and Flexible planning. FTGP adopted a compact graph expansion, which could save time and space of expansion.

GaN ultraviolet photoelectric detecting technique has important application value in the spacecraft, fire monitoring, ultraviolet communication and other fields. In this paper, p-type GaN samples were obtained after rapid annealing of GaN mixing Mg at 700~800°C. Then, p-i-n type GaN ultraviolet photoelectric detectors were fabricated on Al2O3 substrates by metal organic chemical vapor phase epitaxial deposition method. The devices have better rectifying behavior which can be demonstrated by the I-V curve. The response time of the device is 1.6µs and its higher responsivity is 0.95A/W.
