对赋存于岩体内的结构面进行统计分析、分组聚类,是进行岩体工程稳定性分析的基础。考虑到结构面的力学和水力学性质受产状、迹长、张开度、粗糙度和充填状态等诸多因素共同影响,提出一种基于主成分分析的多参数岩体结构面优势分组方法。首先,利用主成分分析法选取多参数岩体结构面优势分组的判据,并计算其参与相似性度量的权重值。进而,基于退火遗传算法搜寻模糊C均值聚类算法的全局最优初始聚类中心。最后,以待分组结构面与聚类中心的距离加权和最小的方式建立目标函数,实现多参数岩体结构面优势分组。对计算机模拟的200个结构面进行多参数优势分组并与其他方法对比,计算结果表明,该方法具有较高的分组精度。将该方法用于重庆市三环高速花阳隧道实测结构面多参数优势分组中,分组结果合理、可靠,进一步验证了该方法具有较好的工程应用价值。

针对方向向量偏差会导致最小均方(LMS)算法的性能急剧下降这一问题,提出了一种基于可变对角载入的顽健自适应波束形成算法。采用最陡下降法对信号方向向量进行优化求解,并在每次迭代过程中更新对角载入值,进而求出最优的权重向量,避免了矩阵求逆运算和特征值分解运算,大大降低了计算复杂度。通过建立步长与输入信号的关系得到可变的步长因子,克服了收敛速度和稳态误差之间的矛盾。该算法收敛速度快,抗扰动性强,对信号方向向量偏差具有很强的顽健性,从而改善了阵列输出的信干噪比,使其更接近最优值。理论分析和仿真结果表明与传统自适应波束形成算法相比,所提顽健算法具有更好的性能。

Based on the hourly precipitation data at 176 observational stations over south China and the hourly ERA5reanalysis data during the 40-yr period of 1981-2020, we analyzed the universal characteristics of moisture transport and their associated background circulations for four types of regional extreme precipitation events(REPEs) over south China. Main findings are shown as follow.(i) The wind that transported moisture for the REPEs over south China featured a notable diurnal variation, which was consistent with the variations of the precipitation.(ii) Four types of REPEs could be determined, among which the southwest type(SWT) and the southeast type(SET) accounted for ~92%and ~5.7%, respectively, ranking the first and second, respectively.(iii) Trajectory analyses showed that the air particles of the SWT-REPEs had the largest specific humidity and experienced the most intense ascending motion, and therefore their precipitation was the strongest among the four types.(iv) South China was dominated by notable moisture flux convergence for the four types of REPEs, but their moisture transport was controlled by different flow paths.(v)Composite analyses indicated that the background circulation of the four types of REPEs showed different features,particularly for the intensity, location and coverage of a western Pacific subtropical high. For the SWT-REPEs, their moisture transport was mainly driven by a lower-tropospheric strong southwesterly wind band in the low-latitude regions. Air particles for this type of REPEs mainly passed over the Indochina Peninsula and South China Sea. For the SET-REPEs, their moisture transport was mainly steered by a strong low-tropospheric southeasterly wind northeast of a transversal trough. Air particles mainly passed over the South China Sea for this type of REPEs.

伦理学的范式转换,不仅与人类文明的发展方向和目标密切相关,而且与哲学本身的奠基原则直接关联。就奠基原则而论,哲学经历了以本体论为第一哲学的古典形态,以知识论为第一哲学的近代形态,在当代出现了以"伦理学为第一哲学"的第三形态。然而恰恰是这第三形态,无论是哲学本身还是伦理学范式本身,都出现了不甚清晰、需要我们加以辨析的深层理论难题。邓安庆教授曾在《分析进路的伦理学范式批判》一文中,首次做出了对分析进路伦理学范式的系统批判,认为分析的伦理学脱离了社会文化的交往语境、摒弃了哲学的存在论根基,而去对伦理学语言单纯进行语义的逻辑分析,必然是个"自败的事业"。此论一出,立刻激起了学界的热烈争论。本组笔谈主要聚焦以下问题与之展开深层论辩,即如何理解分析伦理学和元伦理学之间的关系?如何理解分析进路的伦理范式的意义?如何走出分析进路伦理学的限制?如何理解伦理学与存在论的关系等等。
