美欧学者主导着海外学界关于习近平法治思想的研究,在研究成果、研究队伍和研究话语权上均有明显的体现。美欧学者的研究主要从习近平法治思想的提出背景和原因、中国推进全面依法治国战略的成效以及新时代中国法治建设的国内外影响等方面展开,具有很强的实用主义导向。总体而言,美欧学者肯定习近平法治思想提出的重大意义,认同新时代全面依法治国战略取得的成效,认为习近平法治思想将对中国和世界产生重大影响。归因于对习近平法治思想熟悉程度、研究偏好和知识结构的差异、习近平法治思想的对外传播方式以及意识形态因素的影响,美欧学者对习近平法治思想的认知仍存在一定的差异,部分美欧学者对习近平法治思想的认知偏见和悲观态度一定程度上依然存在。

Ltd.)Beijing 100045China

With the rapid development of inverter-based generators(IGs),power grid is faced with critical frequency stability challenges because the existing IGs have no inertia.To equip IGs with inertial response,researchers have proposed several virtual inertia control methods,which can be classified into two categories:virtual synchronous generator(VSG)control and droop control based on rate of change of frequency(ROCOFdroop control).In this paper,the comparison between both virtual inertia control methods is conducted from three perspectives:mathematical model,output characteristic and small-signal stability.State-space models are firstly built to analyze the control mechanism of VSG control and ROCOF-droop control methods.Simulation and eigenvalue analysis are conducted to study the transient responses and oscillation characteristics of both methods,which is helpful to understand the advantages and limitations of existing virtual inertia control methods.Finally,the obtained theoretical results are validated through realtime laboratory(RT-LAB)hardware-in-loop simulation platform.

In order to examine the potential of using the coupled smooth particles hydrodynamic （SPH） and finite element （FE） method to predict the dynamic responses of aircraft structures in bird strike events, bird-strike tests on the sidewall structure of an aircraft nose are carried out and numerically simulated. The bird is modeled with SPH and described by the Murnaghan equation of state, while the structure is modeled with finite elements. A coupled SPH-FE method is developed to simulate the bird-strike tests and a numerical model is established using a commercial software PAM-CRASH. The bird model shows no signs of instability and correctly modeled the break-up of the bird into particles. Finally the dynamic response such as strains in the skin is simulated and compared with test results, and the simulated deformation and fracture process of the sidewall structure is compared with images recorded by a high speed camera. Good agreement between the simulation results and test data indicates that the coupled SPH-FE method can provide a very powerful tool in predicting the dynamic responses of aircraft structures in events of bird strike.

Multimode fiber(MMF)lasers are emerging as a remarkable testbed to study nonlinear spatiotemporal physics with potential applications spanning from high energy pulse generation,precision measurement to nonlinear microscopy.The underlying mechanism for the generation of ultrashort pulses,which can be understood as a spatiotempoal dissipative soliton(STDS),in the nonlinear multimode resonators is the spatiotemporal mode-locking(STML)with simultaneous synchronization of temporal and spatial modes.In this review,we first introduce the general principles of STML,with an emphasize on the STML dynamics with large intermode dispersion.Then,we present the recent progress of STML,including measurement techniques for STML,exotic nonlinear dynamics of STDS,and mode field engineering in MMF lasers.We conclude by outlining some perspectives that may advance STML in the near future.

“一带一路”倡议是中国构建人类命运共同体的重要举措,对“一带一路”倡议动因的判断直接影响世界各国对该倡议的立场和政策.作为对欧盟及其成员国决策有重要影响的行为体,欧盟智库认为中国提出和实施“一带一路”倡议主要源于追求经济利益、强化国家安全、进行地缘政治竞争以及提升国家形象等考虑.总体来看,欧盟智库对“一带一路”倡议动因的认知是积极和客观的,但仍存在一定程度的不了解、误读甚至是错误认知.鉴于欧盟智库的上述认知受到其对“一带一路”倡议的了解程度、实施进展、学者研究偏好以及意识形态等因素的影响,中国应从国际、国家、次国家等层面多措并举引导欧盟智库对“一带一路”倡议动因的认识,进而影响欧盟对该倡议的立场和政策.

作为世界最大的温室气体排放国和世界第二大经济体,中国气候政策引起了海外学者极大的研究兴趣。海外学者对中国气候政策的研究呈现出明显的阶段性特点,研究重心主要集中在对中国气候政策发展的动力和影响因素、中国国内气候政策、中国气候外交的阐释以及对中国气候政策未来发展的展望等方面。海外学者对中国气候政策的认知总体来说是积极肯定的,但是仍存在不少误读甚至是恶意抹黑的看法。海外学者对中国气候政策的认知与中国气候政策的发展状况、海外学者个人的研究偏好、对中国气候政策的了解程度以及意识形态等因素紧密相关。基于此,中国应从国内和国际两个层面,借助官方和民间两条渠道,通过政府对话、新闻宣传和学术交流等引导海外学者更加客观公正地研究和认知中国气候政策。

中国推动构建人类命运共同体的动因是美欧学界的重要研究议题之一。总体来看,美欧学者对习近平提出人类命运共同体理念意图和原因的认知既有共同点,也存在不小差异。美欧学者的认知与其对习近平人类命运共同体重要理念的了解和熟悉程度、美欧与中国的地缘政治利益、中国对习近平人类命运共同体重要理念的多元解读以及意识形态因素等紧密相关。随着新时代中国日益走近世界舞台的中央,如何让包括美欧学者在内的国际社会形成对习近平人类命运共同体重要理念更加准确和客观的认识将是中国对外传播必须解决的问题。

Particle-like structures of solitons, as a result of the balance between dispersion and nonlinearity, enable remarkable elastic and inelastic soliton collisions in many fields. Despite the experimental observation of temporal vector-soliton collisions in birefringent fibers, collision dynamics of vector solitons in fiber lasers have not been revealed before, to the best of our knowledge. Here, the real-time spectral evolutions of vector solitons during collisions in a dual-comb fiber laser, which generates vector solitons with slightly different repetition rates, are captured by a time-stretch dispersive Fourier transform technique. We record the whole process of vector-soliton collisions, including the formation of weak pulses induced by cross-polarization coupling, opposite central wavelength shifts of both vector solitons, distinct intensity redistribution and dissipative energy, and gradual recovery to initial states. Furthermore, extreme collisions with strong four-wave mixing sidebands are observed by virtue of coherent coupling between the orthogonal polarization components of vector solitons. Numerical simulations match well with the experimental observations. The experimental and numerical evidences of vector-soliton collision dynamics could give insight into the understanding of nonlinear dynamics in fiber lasers and other physical systems, as well as the improvement of laser performance for application in dual-comb spectroscopy.
