非何杰金淋巴瘤患者红细胞膜蛋白成份的改变

本文测定了4例非何杰金淋巴瘤（NHL）患者和10例正常人红细胞膜蛋白电泳。结果显示NHL病人在4.5区出现一染色较深的带,4.5区波峰面积达20.5％,超过正常范围。结果说明:NHL病人红细胞膜蛋白成份也发生了改变,这可能是NHL病人贫血的一新原因,其发生机理有待于进一步研究。     

The Dynamics of the Vibrator-controlled Adaptive Damper and its Potentials in Vibration Isolation

In this paper, the dynamics of a vibrator-controlled adaptive damper is simulated. Its potential in vehicle isolation improvement is demonstrated by a quarter car model. From the results obtained, it is known that after adding a vibrator-controlled flow valve to the conventional hydraulic damper, it is possible to achieve a desired frequency-dependent damping characteristics to provide a large damping at system resonance for the attenuation of the system resonant overshoot, but small damping at higher frequencies to guarantee a good isolation performance. The special feature of this adaptive damper lies in the fact that the damper can be constructed totally mechanically without electronics, which provides a practical way for industrial applications.

铁路机车司机作业稳定性研究

通过１２７６名司机作业稳定性调查结果认为，作业完成量随年龄增长而下降，４０岁以下显著下降。随文化程度降低而减少，小学文化显著减少。后１５ｍｉｎ的作业完成量明显高于前１５ｍｉｎ（Ｐ〈０．０５）。根据本调查提出了我国铁路机车司机作业稳定性的分类标准，从而可区分出机车司机的优劣。作业完成既快又好的人约为４０％。慢而差的人为２０％左右。

Unsteady numerical simulation of flow around 2-D circular cylinder for high Reynolds numbers

In this paper, 2-D computational analyses were conducted for unsteady high Reynolds number flows around a smooth circular cylinder in the supercritical and upper-transition flow regimes, i.e. 8.21×10⁴<Re<1.54×10⁶. The calculations were performed by means of solving the 2-D Unsteady Reynolds-Averaged Navier-Stokes (URANS) equations with a k-? turbulence model. The calculated results, produced flow structure drag and lift coefficients, as well as Strouhal numbers. The findings were in good agreement with previous published data, which also supplied us with a good understanding of the flow across cylinders of different high Reynolds numbers. Meanwhile, an effective measure was presented to control the lift force on a cylinder, which points the way to decrease the vortex induced vibration of marine structure in future.
