The calculated results show that the gap to mid-gap ratio changes slightly with a filling fraction ranging from 0.25 to 0.30. The optimum height-to-pitch ratio is about 1.3. The gap to mid-gap ratio reaches more than 0.18 when the rotation angle increases from 40° to 50° and the maximum gap to mid-gap ratio of 0.2 remains unchanged for the rotation angle from 42°to 48° with a constant height-to-pitch ratio of 1.3. The gap to mid-gap ratio reaches the maximum value of 0.2 when the height-to-pitch ratio is 1.3. This woodpile-type photonic crystal can provide large band gaps within a wider parameter range, which makes it convenient to manufacture three-dimensional photonic crystals in the laboratory.展开更多

The scores of withdrawal symptoms were observed continuously for 20 days. The effect of acupuncture was better than that of Western medicine 48 hours after the withdrawal treatment （P〈 0.05）, and better than that of other three methods 72 hours after the withdrawal treatment, （P〈 0.01）. Acupuncture, Chinese herbs, and acupuncture plus Chinese herbs have the detoxification effects of varying degrees, in particular acupuncture＇ effect was the best. But all the therapies could not completely improve the withdrawal symptoms in the first 3 days of treatment, and acupuncture plus Chinese herbs had no synergetic effect in treating withdrawal symptoms.展开更多
