摘要： Two cylindrical vessels under internal pressure are used for this work in order to study the influence of the position and size of defects on their elastic and elastoplastic behavior. One contains two external longitudinal semi-elliptic defects of different dimensions realized diametrically opposed. The other contains the same defects but is circumferential. These defects are carried out by elect-erosion. Strain gauges are placed in the neighborhood of the defects of which the purpose is to obtain the strain distribution. This work also allows the comparison between two defects of different dimensions, which are of the same shape or different shapes. These defects are longitudinal and circumferential semi-elliptical. The position of these defects relative to the inner radius of a cylindrical pressure vessel is considered. The deformations results are discussed.

摘要： As recorded in classical literature thatacupuncture at Zanzhu(UB 2)points couldimmediately yield effects similar to the de-pression of blood pressure,we made suchpractice with satisfactory results.The sum-mary is as follows.

摘要： The expressions for nucleation rate in metallic melt on the ground and under elevated gravity have been derived theoretically and the effects of gravity and elevated gravity on nucleation rate have been discussed. A comparison of nucleation rate under microgravity with those on the ground and under elevated gravity has also been

摘要： Totally 20 cases of mental depression were treated by needling extrachannel points with an effec-tive rate of 90%; comparison of these cases with 21 controls treated with amitriptyline, showed no significant difference in effect (P0.05). Measured with Hamilton’s scale, factors of anxiety somatization, cognitive disturbance, retardation, sleep disturbance and feeling of despair in both the needling and control groups showed obvious decrease in the mean value, and the change in anxiety somatization was markedly significant in the needling group as compared with that in the controls (P 0.01). Our studies revealed that after 6 weeks of needling the power of slow wave 5 decreased while that of the fast wave a increased, all significantly different as compared with that before and during the treatment (P 0.05).
