This paper briefly described borehole wave velocity test and the principle and method of wave velocity test technique, by using acoustic measurement and control technology of tunnel rock mass test, integrality index of rock mass is obtained, ultimately, we evaluate the rock mass integrity. The actual application effect is good and provides an important basis for the engineering rock mass quality evaluation.

Abstract CTD measurements taken as an integral part of oceanographic cruises could provide valuable information on spatial locations and time variability of significant shear-generated mixing in the ocean interior if used routinely to calculate Thorpe scales, that is, estimates of the scales of vertical overturning in an otherwise stably stratified fluid. This paper outlines methods for calculating reliable Thorpe scales from density profiles taken with a shipborne CTD, including removal of questionable instabilities associated with termination of pressure reversals, reduction of the effects of density noise by computation of an intermediate density profile, and overturn verification by a two-parameter (Ro, ΔN) diagnostic. The Ro criterion alone reliably removes overturns that result from salinity spikes at the high gradient boundaries of a weakly stratified layer, a common cause of highly suspect overturns. The ΔN diagnostic is a new water mass test describing the degree of “tightness” of the temperature–salinity (T–S) relationship. The present two-parameter diagnostic rejects a significantly larger percentage of suspect overturns than does a previous single-parameter water mass test. Despite developing a more reliable water mass diagnostic, the authors conclude that rejection of overturns based on a water mass test that incorporates expectation of T–S tightness is not warranted, given possibilities of T–S “looseness” resulting from mixing over regions of nonlinear T–S structure and/or from potential effects of differential diffusion.

Electromagnetic Damper

Abstract Compressors, turbines and other rotating machines often have long thin shafts which may cause vibration problems. An electromagnetic damper placed on the rotor of a machine represents one method of controlling high levels of vibrations. This paper discusses experimental results of an electromagnetic damper placed on a small three mass test rotor. Experimental data was taken for cases with the damper at three different locations on the highly unbalanced rotor to study the effectiveness of the damper in controlling vibrations at the first and second rotor bending modes and at a pedestal response mode. Reductions of vibrations up to 88%, 40%, and 19% were achieved for the first critical speed, second critical speed, and pedestal response mode, respectively. Values of magnetic damper stiffness and damping used to obtain these reductions were only a small fraction of the fluid film bearing damping and stiffness properties.

Relatively long-lasting metabolic alkalizing procedures such as bicarbonate ingestion have potential for improving performance in long-sprint to middle-distance events. Within a few minutes, hyperventilation can induce respiratory alkalosis. However, corresponding performance effects are missing or equivocal at best.Purpose:To test a potential performance-enhancing effect of respiratory alkalosis in a 30-s Wingate Anaerobic Test (WAnT).Methods:10 men (mean ± SD age 26.6 ± 4.9 y, height 184.4 ± 6.1 cm, body-mass test 1 80.7 ± 7.7 kg, body-mass test 2 80.4 ± 7.2 kg, peak oxygen uptake 3.95 ± 0.43 L/min) performed 2 WAnTs, 1 with and 1 without a standardized 15-min hyperventilation program pre-WAnT in randomized order separated by 1 wk.Results:Compared with the control condition, hyperventilation reduced (all P < .01) pCO2 (40.5 ± 2.8 vs 22.5 ± 1.6 mm Hg) and HCO3− (25.5 ± 1.7 vs 22.7 ± 1.6 mmol/L) and increased (all P < .01) pH (7.41 ± 0.01 vs 7.61 ± 0.03) and actual base excess (1.4 ± 1.4 vs 3.2 ± 1.6 mmol/L) pre-WAnT with an ergogenic effect on WAnT average power (681 ± 41 vs 714 ± 44 W) and total metabolic energy (138 ± 12 vs. 144 ± 13 kJ) based on an increase in glycolytic energy (81 ± 13 vs 88 ± 13 kJ).Conclusion:Hyperventilation-induced respiratory alkalosis can enhance WAnT cycling sprint performance well in the magnitude of what is seen after successful bicarbonate ingestion.

The paper presents the behavior of the motion properties of the variable mass test particle (third body), moving under the influence of the two equal primaries having electromagnetic dipoles. These primaries move  on the same circular path around their common center of mass in the same plane. We have determined the equations of motion of the test particle whose mass varies according to Jean's law. Using the system of equations of motion we have evaluated the locations of equilibrium points, their movements and basins of the attracting domain. Finally, we examine the stability of these equilibrium points, all of which are unstable.
