We have experimentally studied the energy spectra of Ar ions emitted from Ar clusters irradiated by intense femtosecond laser pulses. The Ar clusters were produced in the adiabatic expansion of Ar gas into vacuum at high backing pressures. The laser peak intensity was about 2×106 W/cm2 with a pulse duration of 45 fs. The maximum and the average energies of Ar ions are 0.2 MeV and 15kev at a backing pressure of 2. S MPa, respectively. They are almost independent of the backing pressures in the range of 0.6 to 4.5 MPa.

数字技术创新是新质生产力的组成部分,出口产品质量升级是高质量开放发展的基本要求。聚焦数字技术创新对出口产品质量的影响,从而探讨新质生产力促进高质量发展的渠道、机制和障碍,理论分析表明:数字技术创新降低资源投入、提升资源效率影响在位企业产品质量、临界企业产品质量和整体平均产品质量,对平均产品质量的影响具有不确定性。实证分析发现,数字技术创新自身难以提升平均产品质量,但与传统技术创新交叉项却显著稳健为正,这体现了数实融合、新旧融合的必要性;这一作用对中高技术产品并不显著,意味着中高技术产品质量升级可能更依靠技术创新质量;上述结论在考虑测量误差、样本选择、内生性等因素后依然显著。促进数字技术创新与传统技术创新融合是提升产品质量、促进高质量发展的关键,新质生产力无法孤立于旧生产力而发挥作用。

Implementation of Deutsch-Jozsa Algorithm with Superconducting Quantum-Interference Devices via Raman Transition

引用

Communications in Theoretical Physics 2009年第1期51卷 135-138页

作者： zhan zhi-Ming School of Physics ＆ Information Engineering Jianghan University Wuhan 430056 China

In this paper, a theoretical scheme is proposed to implement the Deutsch-Jozsa algorithm with SQUIDs （superconducting quantum-interference devices） in cavity via Raman transition. The scheme only requires a quantized cavity field and classical microwave pulses. In this scheme, no transfer of quantum information between the SQUIDs and the cavity is required, the cavity field is only virtually excited and thus the cavity decay is suppressed.

In this paper, a scheme is proposed to create the entanglement of two superconducting quantum-interference devices （SQUIDs） and implement a two-quhit quantum phase gate between two SQUIDs in cavity. The scheme only requires resonant interactions. Thus the scheme is very simple and the quantum dynamics operation can he realized at a high speed, which is important in view of decoherence.

One-Step Realization of SWAP Gate with Superconducting Quantum-Interference Devices and Atoms in Cavity QED

引用

Communications in Theoretical Physics 2008年第6期49卷 1603-1606页

作者： zhan zhi-Ming School of Physics and Information Engineering Jianghan University Wuhan 430056 China

We put forward a simple scheme for one-step realization of a two-qubit SWAP gate with SQUIDs （superconducting quantum-interference devices） in cavity QED via Raman transition. In this scheme, the cavity field is only virtually excited and thus the cavity decay is suppressed. The SWAP gate is realized by using only two lower fiux states of the SQUID system and the excited state would not be excited. Therefore, the effect of decoherence caused from the levels of the SQUID system is possibly minimized. The scheme can also be used to implement the SWAP gate with atoms.

The ionization behavior of linear polyatomic molecular ions in ultrashort,intense laser fields was investigated with the time-dependent Schrodinger equation solved by the standard split-operator *** enhanced ionization effect was found as a general feature in the ions when the internuclear separation was in a critical distance range and can be explained in terms of the field-induced over-barrier ionization *** addition,the ionization energy does not influence the ionization probability significantly.

Mechanism and simulation of droplet coalescence in molten steel

引用

International Journal of Minerals,Metallurgy and Materials 2017年第11期24卷 1251-1259页

作者： Bing ni Tao zhang Hai-qi ni zhi-guo Luo Department of Metallurgical Technology Central Iron and Steel Research Institute School of Metallurgy Northeastern University

Droplet coalescence in liquid steel was carefully investigated through observations of the distribution pattern of inclusions in solidified steel samples. The process of droplet coalescence was slow, and the critical Weber number(We) was used to evaluate the coalescence or separation of droplets. The relationship between the collision parameter and the critical We indicated whether slow coalescence or bouncing of droplets occurred. The critical We was 5.5, which means that the droplets gradually coalesce when We ≤ 5.5, whereas they bounce when We > 5.5. For the carbonate wire feeding into liquid steel, a mathematical model implementing a combined computational fluid dynamics(CFD)–discrete element method(DEM) approach was developed to simulate the movement and coalescence of variably sized droplets in a bottom-argon-blowing ladle. In the CFD model, the flow field was solved on the premise that the fluid was a continuous medium. Meanwhile, the droplets were dispersed in the DEM model, and the coalescence criterion of the particles was added to simulate the collision-coalescence process of the particles. The numerical simulation results and observations of inclusion coalescence in steel samples are consistent.
