官能与意志:荀子论心的两重维度

哲学动态 2024年第7期 43-52页

作者：刘雷山东大学儒学高等研究院

心是荀子哲学中的一个重要概念,具有丰富的内涵与特质。学界对于荀子论心的认知分歧主要集中在“认识心”与“道德心”的讨论上,双方各自依据《苟子》文本中有关善、恶的直接材料来进行论说,故纠缠无尽。一,我们应跳出前人研究的认识案... 详细信息

心是荀子哲学中的一个重要概念,具有丰富的内涵与特质。学界对于荀子论心的认知分歧主要集中在“认识心”与“道德心”的讨论上,双方各自依据《苟子》文本中有关善、恶的直接材料来进行论说,故纠缠无尽。一,我们应跳出前人研究的认识案白和方法栓楷,如从善的发生与善的存在的视域来探究荀子论心的主体性内涵。另一方面,尽可能的吸收前人研究成果,从官能与意志等维度来探究苟子言心的真实状貌,以阐明它们与善的发生及善的存在的内在关系。

民国时期《火烧红莲寺》不仅是一部民俗内容丰富的影片,而且其兴衰过程也被卷入了20世纪二三十年代关于民俗的话语漩涡中,既出现了“民族”与“迷信”两种矛盾性话语异化,也表现为民俗本位下集体无意识对“话语”的反干预,成为社会转型时期民俗认知与实践的一个缩影。

This study investigated the effect of antioxidants on the grinding efficiency, magnetic powder characteristics, microstructure, and magnetic properties of 2:17 type SmCo permanent magnet materials. The results show that adding antioxidants helps improve the dispersion among magnetic powders, leading to a 33.3% decrease in jet milling time and a 15.8% increase in magnet powder production yield. Additionally, adding antioxidants enhances the oxidation resistance of the magnetic powders. After being stored in a constant temperature air environment at 25 degrees C for 48 h, the O content in the powder decreased by 33% compared to samples without antioxidants. While in the magnet body, the O content decreased from 0.21 wt.% to 0.14 wt.%, which helps increase the effective Sm content and domain wall pinning uniformity in the magnet. Excellent magnetic properties were obtained in the magnet with added antioxidants: B-r = 11.6 kGs, SF = 79.6%, H-cj = 16.8 kOe, and (BH)(max) = 32.5 MGOe.

以清洁能源发电为代表的零碳机组大规模并入电网,其间歇性和不确定性带来的频率波动愈发凸显。针对电池储能辅助火电机组调频灵活性不足、荷电状态维持效果不理想的问题,提出一种基于调频信号自适应分解的储能辅助二次调频控制策略。首先,综合灵敏度、储能荷电状态、频率偏差状态3个因素,给出区域调节需求信号和区域控制误差信号的切换时机判据;计及火电机组爬坡率限制和储能荷电状态限制,提出自适应调频信号分解策略,构建回报增益与荷电状态之间的规律并将其作为调节参考值,利用频率偏差对参考值进行修正,最后通过状态一致性检测模块判断回报增益的输出,以实现2种调频资源的优势互补。通过单区域系统频率响应模型仿真,验证了本文策略的有效性。结果表明:本文策略能够提高系统的灵活性,使各调频资源形成互补关系。

连续油管作业中遇到的软阻、软卡现象会增大作业风险,而油管弯曲变形导致的连续油管软阻、软卡,其判断方式较难,传统的陀螺仪测井斜等方法也难以明确。采用排除法,通过循环冲洗、钢丝探查、连续油管钻磨等工艺依次排除井筒结蜡、沥青及结垢的可能性,判定油管弯曲,并用钢丝短工具串进一步验证,建立了连续油管作业中软阻、软卡的分析步骤和对应的处理方法。通过XX井的现场实践,应用连续油管作业中油管弯曲变形的判断方法,最终判定油管弯曲是导致连续油管遇卡的原因,并用相应的处理方法成功解卡。该方法可为同类型连续油管遇阻遇卡问题的处置提供借鉴。

结合CPU涡轮风扇的注射成型要求,采用CAE辅助分析优化得到了塑件的成型方案为1模1腔、正面中心轴顶端进浇模腔布局,单点热嘴环形热浇口浇注。利用分层抽芯的方法将单个涡轮叶槽的脱模采用上、中、下3层滑块的顺序实施抽芯的方法进行侧抽芯脱模,从而得到整个涡轮风扇叶槽的所需脱模机构为27个滑块机构,分别为上层9个上滑块机构、中层9个中滑块机构、下层9个下滑块机构。根据滑块机构的抽芯驱动需要,将模具的整体结构采用一种假三板模结构,分3次开模,第一次开模用作下层9个滑块机构的侧抽芯驱动;第二次开模用作上层9个滑块机构的侧抽芯驱动;第三次开模用作塑件的完全脱模,第三次开模打开后,随着中层9个油缸驱动9个中滑块侧抽芯动作的完成,塑件自动脱落而实现完全脱模。结合涡轮风扇叶槽难以脱模的实践难题,设计了3层滑块机构按序抽芯,根据模具开模提供的驱动进行设计,有效地解决了涡轮风扇塑件的成型难题,机构动作可靠,生产效率较高。
