我们研究了在2.7Ni-0.45Cr-0.5Mo-0.1V钢中,降低硅含量对机械性能的影响,以便为了解决钢锭偏析问题,采用低硅钢来制造高压-低压整体转子轴。降低硅合量时,可以改善韧性和回火脆化,但在500℃以下的温度,抗张强度也会降低。这一点可以用增加少量的铬来得到充分补偿,而不致损害其他性能。不管降低硅或是增加铬,蠕变断裂强度都不会发生变化。川崎钢铁公司曾经发展一种特殊的炼钢方法,可以制出磷硫和其他杂质都很低的高级钢。用此法实地制成了一根整体的转子轴,试验证明它具有令人满意的机械性能,正象我们进行初步的研究后所预期的那样。

Dynamic stabilization of plasma instability

引用

High Power Laser science and Engineering 2019年第1期7卷 17-26页

作者： s.Kawata T.karino Y.J.Gu Graduate school of Engineering Utsunomiya University Institute of Physics of the AsCR ELI-Beamlines Institute of Plasma Physics of the CAs

The paper presents a review of dynamic stabilization mechanisms for plasma instabilities. One of the dynamic stabilization mechanisms for plasma instability was proposed in the paper [Kawata, Phys. Plasmas 19, 024503(2012)],based on a perturbation phase control. In general, instabilities emerge from the perturbations. Normally the perturbation phase is unknown, and so the instability growth rate is discussed. However, if the perturbation phase is known, the instability growth can be controlled by a superimposition of perturbations imposed actively. Based on this mechanism we present the application results of the dynamic stabilization mechanism to the Rayleigh–Taylor instability(RTI) and to the filamentation instability as typical examples in this paper. On the other hand, in the paper [Boris, Comments Plasma Phys. Control. Fusion 3, 1(1977)] another mechanism was proposed to stabilize RTI, and was realized by the pulse train or the laser intensity modulation in laser inertial fusion [Betti et al., Phys. Rev. Lett. 71, 3131(1993)]. In this latter mechanism, an oscillating strong force is applied to modify the basic equation, and consequently the new stabilization window is created. Originally the latter was proposed by Kapitza. We review the two stabilization mechanisms, and present the application results of the former dynamic stabilization mechanism.

In this review paper on heavy ion inertial fusion(HIF),the state-of-the-art scientific results are presented and discussed on the HIF physics,including physics of the heavy ion beam(HIB)transport in a fusion reactor,the HIBs-ion illumination on a direct-drive fuel target,the fuel target physics,the uniformity of the HIF target implosion,the smoothing mechanisms of the target implosion non-uniformity and the robust target *** HIB has remarkable preferable features to release the fusion energy in inertial fusion:in particle accelerators HIBs are generated with a high driver efficiency of~30%-40%,and the HIB ions deposit their energy inside of ***,a requirement for the fusion target energy gain is relatively low,that would be~50-70 to operate a HIF fusion reactor with the standard energy output of 1 GWof *** HIF reactor operation frequency would be~10-15 Hz or ***-MJ HIBs illuminate a fusion fuel target,and the fuel target is imploded to about a thousand times of the solid *** the DT fuel is ignited and *** HIB ion deposition range is defined by the HIB ions stopping length,which would be~1 mm or so depending on the ***,a relatively large density-scale length appears in the fuel target *** of the critical issues in inertial fusion would be a spherically uniform target compression,which would be degraded by a non-uniform *** implosion non-uniformity would be introduced by the Rayleigh-Taylor(R-T)instability,and the large densitygradient-scale length helps to reduce the R-T growth *** the other hand,the large scale length of the HIB ions stopping range suggests that the temperature at the energy deposition layer in a HIF target does not reach a very-high temperature:normally about 300 eV or so is realized in the energy absorption region,and that a direct-drive target would be appropriate in *** addition,the HIB accelerators are operated repetitively and *** precis
