Temperature dependence of the stacking fault energy of glide set-dissociated dislocations in Si

Recently, it was found that the dissociation distance of glide set dislocations introduced in Si just below the melting temperature by laser shock peening (LSP) is unusually wide (Iwata et al. J. Jpn Inst. Met. Materi.,79(2015),308–314). In order to distinguish whether or not this is to be attributed to uncorrelated motions of leading and trailing Shockley partials or the intrinsic temperature dependence of the stacking fault energy (SFE), dislocations introduced by LSP were annealed at 1350 °C, which should be high enough for the uncorrelated partials to assume the equilibrium correlated configuration. It was found that this unusual widening of a dissociated dislocation introduced by LSP is attributed to uncorrelated motions of Shockley partials. Following this conclusion, the temperature dependence of the intrinsic SFE of Si was determined on correlated dissociated dislocations up to near the melting temperature. The intrinsic SFE of Si shows only negligibly small temperature dependence from 400 °C up to near the melting temperature.     

A new orthorhombic approximant of the icosahedral Al–Cu–Fe quasicrystal

We report on the formation of a new crystalline approximant phase of the icosahedral (i-)Al–Cu–Fe quasicrystal. This phase is formed during sintering of Al-based composites reinforced with i-AlCuFeB quasicrystalline particles. The structure of this phase has been characterized by transmission electron microscopy (TEM) and high-resolution electron microscopy (HREM). TEM revealed that it is a B-centred orthorhombic phase with lattice parameters a = 1.166 nm, b = 1.195 nm and c = 3.44 nm. Its chemical composition, as determined by electron energy loss spectroscopy (EELS), is close to Al_76.9Cu_2.7Fe_20.4, with an average number of valence electrons per atom e/a of 1.92, similar to the value in all other approximants of the i-phase discovered thus far. Initial results on local atomic arrangements along one of its pseudo-5-fold axes are also presented.     

On the possibility of tuning the energy separation between space-quantized levels in a quantum well

The idea about change of energy distances between space-quantized energy levels by ionization of an impurity delta layer situated within a quantum well (QW) is put forward and justified. The self-consistent solutions of Schrödinger, Poisson, and electroneutrality equations made for n-type SiGe/Si/SiGe rectangular QW show that the effect really exists and the most dramatic changes can be observed for an edge-delta-doped QW structure.     

Effects of Si addition on the microstructure evolution of Al–Cu–Mg alloys in the α + S + T phase field

The precipitation behaviour and age-hardening response of Al–1.5Cu–4.0Mg (wt.%) alloys microalloyed with Si have been investigated by means of hardness measurement, TEM and HRTEM. Compared to the ternary alloy, the quaternary alloys exhibit a higher hardness. It is found that the underaged microstructure in the Al–1.5Cu–4.0?Mg alloy contains some fine precipitates, which are identified as the T phase by FFT spectra. The peak-aged microstructures of the ternary alloy is dominated by the T phase, while the peak-aged microstructures of the Si-containing alloys are dominated by the S phase. The volume fraction of the S phase is found to increase as more Si is added.     

Li,Qing, and Ethical Transformation in the Xunzi

This paper analyses the connection between knowing Dao and ethical transformation in Xunzi’s thought. While there have been many discussions concerning what Dao is and how one may come to Dao, there has not been sufficient attention on how knowing Dao leads to ethical transformation. In Section 2, I explicate Xunzi’s concept of bi 蔽 (obscurity) and suggests that one’s not knowing Dao has to do with a certain problematic state of the heart/mind. In Section 3, I analyse xu虛 (vacating), yi 一 (focusing), and jing 靜 (stilling), which are remedial practices for knowing Dao, and bring out the importance of discerning li 理 for Xunzi. In Sections 4 and 5, I propose an interpretation of the relation between li 理 and qing 情 in the process of ethical transformation. In Section 6, I highlight some remaining ambiguities that can be further investigated to deepen our understanding of Xunzi’s thought.     

理性化的情感——东汉“矫情崇礼”现象探究

东汉出现了一股"矫情崇礼"的社会风气,表象背后是儒家礼制的日益渗透和"人情"的逐渐被"恶"化。面对情礼关系这个纷杂却又永恒的人生课题,"矫情崇礼"现象的出现彰显了东汉独有的时代特征。     

论《周易》的道德谱系

《周易》是一部人学著作,也是一部道德著作。《周易》构建了一种特殊的道德谱系,这种道德谱系由本能无意识、文化无意识、社会意识、自我意识道德化四个层面构成。《周易》的道德谱系把“人”与“道”联系起来,从而有了“人道”,也把“道”与“德”联系起来,从而有了“道德”。《周易》在性命之理的基础上探讨了人的形成、演化及人性的内容;又在“人”与“道”的基础上构建了“成人”与“做人”的道德谱系。《周易》的道德谱系把“人”与“道”联接起来是人学,把“道”与“德”联接起来是伦理学。天道、人道等统一于性命之理的命题之中,成为了道德谱系的奇特内容,从而人也就成为了道德谱系的本体。     

Modernization of Confucian ontology in Taiwan and mainland China

The present paper compares three models of modernized Confucian Ontology. The philosophers under debate belong to the most important, well-known and influential theoreticians in modern Taiwan and mainland China respectively. Through a contrastive analysis, the paper aims to critically introduce three alternative models of ontology, which have been developed from the Chinese philosophical tradition by the most well-known Taiwanese philosopher Mou Zongsan and by two most influential mainland Chinese theoreticians, Li Zehou and Chen Lai respectively. In this paper, I will analyze and critically introduce Li Zehou’s and Chen Lai’s respective critiques of Mou Zongsan’s basic assumptions that have been reflected in his methodological paradigms, while also exposing some major differences within their own lines of thought.     

陈立与20世纪中国工业心理学

陈立的工业心理学生涯跨越70年, 但主要活动集中于1935至1937年, 1977至1990年代中期, 中断40年而再续, 可谓波澜起伏。除了1935年撰写的《工业心理学概观》, 陈立的主要贡献源于后一阶段, 其中包括：恢复了中断多年的中国心理学教学和研究、建立了中国第一个与管理有关的专业(工业心理学)和第一个国家重点实验室、培养了国内第一批工业心理学硕、博士、继承和发扬了实地调研—实验室研究—理论学习相结合的工业心理学传统; 陈立还通过写作和其他形式的呼吁, 促成了中国管理学的兴盛。但他晚年却觉得自己一生是失败的, 主要是因为他认为工业心理学没能做到 “指导人走向最适宜的机会, 并在此过程中实现最高的自我”。     

"理"能否活动? --李退溪对朱子理气论的诠释

李退溪是朝鲜性理学之巨擘,其学以朱子学为宗。他曾撰文严厉批评王阳明。在李退溪与奇高峰关于“四端七情”的辩论中,双方均援引朱子的文献作为论据,且自认为忠于朱子的观点。然究其实,李退溪对孟子“四端”说的诠释预设了一套与朱子性理学系统不同的义理架构,虽然合乎孟子的文本,但却脱离了朱子的基本立场。这其中最关键的问题是：“理”能否活动?在朱子的性理学中,理是气之所以然,只存有而不活动。本文根据相关文献证明：李退溪在诠释朱子的理气论时有意无意地赋予理一种活动性,而逸出了朱子性理学的架构。
