The Bohai Sea is one of the southernmost areas for sea ice formation in the northern *** ice disasters in this body of water severely affect marine activities and the safety of coastal *** this study,we analyze the variation characteristics of the sea ice in the Bohai Sea and establish an annual regression model based on predictable mode analysis *** results show the following:1)From 1970 to 2018,the average ice grade is(2.6±0.8),with a maximum of 4.5 and a minimum of *** Bay(LDB)has the heaviest ice conditions in the Bohai Sea,followed by Bohai Bay(BHB)and Laizhou Bay(LZB).Interannual variation is obvious in all three bays,but the linear decreasing trend is significant only in BHB.2)Three modes are obtained from empirical orthogonal function analysis,namely,single polarity mode with the same sign of anomaly in all of the three bays and strong interannual variability(82.0%),the north–south dipole mode with BHB and LZB showing an opposite sign of anomalies to that in LDB and strong decadal variations(14.5%),and a linear trend mode(3.5%).Critical factors are analyzed and regression equations are established for all the principal components,and then an annual hindcast model is established by synthesizing the results of the three *** model provides an annual spatial prediction of the sea ice in the Bohai Sea for the first time,and meets the demand of operational sea ice forecasting.

In order to solve the problem of the accurate positioning of the welding robot in the automatic bar production, this paper proposes a positioning method of the welding robot based on machine vision and laser ranging. The traditional positioning method of welding robot mainly adopts the Hand-eye calibration mode, however, the essence of Hand-eye calibration is to obtain the conversion relationship from camera coordinate system to robot end actuator coordinate system through complex matrix operation. The calculation process of this method is too lengthy, and it is difficult to achieve the required accuracy of welding. The precise positioning of welding robot mainly includes plane coordinate positioning and depth positioning. First of all, this paper is based on the principle that the distance between the camera and the object to be photographed and the size of the camera image are proportional to the size of the object, the pixel coordinates obtained from the image processing are transformed into the plane coordinates of the final target point to be welded by the method of machine vision. At the same time, in view of the distortion caused by the camera in the imaging process, this paper uses the Zhang calibration method to correct the distorted image. Finally, the resistance detection circuit proposed is used to determine the final welding position. The experimental results show that the positioning method of the welding robot has the advantages of easy realization and high positioning accuracy, which can fully meet the welding requirements and improve the efficiency of automatic welding of the label.

环境决策算法化衍生风险及其法律规制

AI时代,算法以弥散性的方式迅速扎根生态环境领域,而且在不断深入与扩张。以数据为基础的算法借助自动化分析,内嵌环境决策各环节,决策效率极大提升,环境决策日趋算法化。然而,算法技术在提高环境决策质量与速度的同时,也将“算法黑箱”“算法霸权”“算法歧视”等基因性风险带入了决策过程,衍生环境决策失准、专业壁垒倍增、公众参与程度低等场景化风险。这种复合性的内生风险统一表现为政府信任危机、环境非正义加剧、环境保护公众参与权悬置,因此,直接限制了算法在生态环境领域的功能发挥。究其根源,环境决策与算法在互动过程中,环境决策的公开性、风险性、社会性与算法的不透明性、自主性、资本性不乏对立、叠加及互斥。算法的介入,使得其与环境决策的属性矛盾,不仅无法得到及时缓冲,反而进一步激化。由此可见,规制环境决策算法化衍生风险的关键在于调和环境决策与算法本质属性的矛盾。为此,该研究立足环境决策算法化所带来的“利”与“弊”,透析其衍生风险的内在逻辑,对环境决策与算法的本质属性进行适当的“扬抑”,从而提出具有针对性的场景化规制路径。所谓的“扬抑”,本质上是对算法技术与环境决策制度内涵利益之衡量。由此,为确保算法在生态环境领域的高效能运行,该研究以环境决策算法化的公开与透明、重监管严问责、公众的全面参与为规制路径,增加算法透明度,削弱算法及环境决策的不确定性,抑制算法的资本性,扶持环境决策的公开性与社会性,从而调和二者的属性矛盾,衡平各方利益,促进环境决策制度的健康发展。
