在多年的艺术创作中,我一直坚持油画写生,坚持在生活的第一现场进行记录、创作,因为它可以更大程度上激发和丰富自己的创作感受。大尺幅多人物组合的油画写生,因其尺幅巨大、人物组合关系复杂,较之一般油画,整体思想性表达更强烈,刻画的人物形象更丰富、更具感染力,成为我近年来在油画写生中用力最深、倾注感情最多的创作形式。本文基于近年来的切身经历,不断探索创作规律、总结经验教训,希望能为新时代美术创作的繁荣发展贡献力量。

肺部小结节术中冷冻切片病理诊断中的常见问题及解决策略

第43届中国控制会议

作者： Can Li Zhuangzhuang Nie yuchen han School of Electrical Engineering and Automation Jiangsu Normal University

This paper is concerned with the tracking control of high-speed trains(HSTs) with model uncertainties, unknown nonlinear resistances and external disturbances. Both continuous and intermittent control methods are studied. Under continuous feedback, to cope with the unknown Davis coefficients and unknown parameters in train's additional resistances, a new adaptive control law is developed. Under intermittent feedback, the system dynamics of HSTs are formulated by a switched system. Then,a bilateral state-dependent switching law is proposed to orchestrate the intermittent control of HSTs. Based on the proposed control algorithm, the train's position and speed can track their desired profiles in adjustable steady-state errors. A numerical simulation is given to show the effectiveness of the proposed results.

随着胸部CT筛查的广泛开展,可手术的肺部肿瘤从以往的以大肿块为主转变为目前的以小结节为主。肺部小结节术中冷冻切片病理诊断面临诸多挑战,比如对原位腺癌、微浸润性腺癌、贴壁生长型腺癌等概念的准确掌握,以及它们与小的浸润性腺癌、良性肿瘤(如细支气管腺瘤、硬化性肺细胞瘤等)、转移性肿瘤的鉴别诊断等。本文对目前临床实践中肺部小结节的术中冷冻切片病理诊断遇到的一些常见问题加以总结,重点围绕腺癌的诊断和鉴别诊断,以更好地完成肺部小结节的术中冷冻切片病理诊断,减少误诊。

作者： han yuchen Wang Hongjian Yu Dan Wang Zhao College of Intelligent Systems Science and Engineering Harbin Engineering University

Aiming at the multi-UUV target pursuit-evasion game under the condition of strongly moving ability of the target,the necessary conditions for the pursuers to capture the evader were studied, including the minimum number of pursuers and the distribution of initial position required to capture the evader. In this paper, we propose a pursuers cooperation strategies and an evader strategies based on UUV interception and breakthrough game strategies by using geometry method. Firstly, the kinematics model and controller of UUV is constructed. Then, the control characteristics of UUV are introduced into the strategies of pursuitevasion game. Finally, two typical simulation cases are designed to verify the rationality of the proposed strategies. The results show that the proposed multi-UUV pursuit-evasion game strategies can effectively capture the evader with strongly moving ability.

Applications of electric vehicles need to build a large number of charging stations. The electric vehicle charging stations communicate with the grid. In V2G （vehicle to grid） mode, electric vehicles can be used as energy storage units and transfer power to the grid. The electric vehicles charge at night to reduce the cost and the grid load, simultaneously to fill the valley. When grid load increases, electric vehicles＇ batteries discharge to the grid to improve the stability of the grid. As distributed storage units, electric vehicles are important components of the smart grid. In this paper, the three-phase PWM （pulse width modulation） rectifier used for smart charging and discharging system of electric vehicles are analyzed and designed. This paper includes the principle of PWM rectifier-inverter and direct current control strategy. Also, the SVPWM （space vector pulse width modulation） and system design of three-phase PWM rectifiers are analyzed. A 10 kW prototype is developed. Simulation and experiment results show that the three-phase PWM rectifiers reach the unit power factor. From the experimental results, PWM rectifier implements the sinusoidal grid current and achieves the unit power factor.
