2020年2月自武汉封城，上海新冠疫情愈演愈烈。女儿线上学习、我日常的节奏被打乱，在电脑上写点无意识的记忆文字。提振心神应对日常，事后看这七章成就灾难共和国三部曲之二：《新冠世代城乡中国彩虹桥》。三年大疫，全球两千万人死亡（包括我的奶奶），紧急状态接踵而至，让人目不暇给。几乎每位邻居都有居家隔离的孤独、无聊、愤怒与恐慌。大乱来临，往事浮上心头。本书曾在朋友圈预告，好友好奇文体是否不是专业论文写作。我肯定的答复：散文体。能够自由率性写作是人到中年的福利。许多章节都发给学生先阅读，反馈尚佳。于是我鼓足勇气继续这种文风，偶尔有些注释是实在觉得与作者有缘。 看到王朔先生在《起初-纪年》开篇写道："想到了历史体裁麻烦，细节考证能累死谁，全知等于难为自己，故取惯常所用第一人称，所见限于一己之侧，能少交待少交待，是不得已......有些人物所行骇人，心机莫测，远超常人所想所能驾驭，亦为第一人称天然具有同情之理解所不容，故在很多篇幅陆续出现第一、第三人称混用章节，乃至最后写丢了第一人称，通篇以第三人称尬然终了。"真是击节赞叹，第一、第三人称混用的同理、尬然和无意识，不能同意再多。本书亦引用了这三年的微信朋友圈文字，都是当时新鲜的文字，更是第一人称。本书本来写的是彩虹桥。三年大疫之后，再读到托尔金的《魔戒》恍悟，也是甘道夫丧生/死而复生的凯萨督姆大桥（Khazad-dûm Bridge）。这新冠就像炎魔的火鞭要了多少人的命，但也将四位哈比少年送达安全的彼岸，开启了希望征途。

While linear control is a well-established subject, analysis and design of nonlinear control systems remains a challenging topic due to some of the fundamental difficulties caused by nonlinearity. This book provides a unified computational approach to analysis and design of nonlinear systems.

This book adopts a multi-method and multi-phase approach to investigate the washback effects of Test for English Majors (TEM) on program administrators, teachers and students, shedding new light on TEM reform and the reform of English teaching and learning in China.

This book addresses anti-fatigue manufacturing, analysis and test verification technologies for typical aircraft structures, including fastening holes, shot peening plates, different types of joints and wing boxes.

The trend within English teaching in China is for 'communicative competence' - that is, in being understood even if the English usage is incorrect. This volume argues that more solid grammar teaching must be coupled to this communicative competence, if English language teaching in China is to be successful.

The book provides the suitable theoretical logical background of lattice-valued logic systems and supports newly designed intelligent uncertain-information-processing systems and a wide spectrum of intelligent learning tasks.

Access Chinese gives a new perspective to teaching and learning Chinese by harmonizing 3 key elements of learning a second language creatively: 1.Intertwining language with culture 2.Balancing focus on forms and meaning 3. Developing literacy skills through both oral and written Chinese. This book treats culture as the glue that connects the units by following the story lines of a twin brother and sister learning Chinese in two contexts (China vs. US). Access Chinese provides essential tools for communication throughout the story development while at the same time engaging learners in acquiring additional vocabulary and grammar by contextualizing these elements in further communicative tasks. Also, Access Chinese uses colloquial Chinese as a starting point for engaging the learner while also introducing the nuance of Chinese philosophy and deeply imbedded Chinese etiquettes and rituals in communication to bring about the curiosity and appreciation of the language and culture.

Gives a fresh perspective to teaching and learning Chinese by harmonizing 3 key elements of learning a second language creatively: Intertwining language with culture; Balancing focus on forms and meaning; and, Developing literacy skills through both oral and written Chinese.

Nanostructures refer to materials that have relevant dimensions on the nanometer length scales and reside in the mesoscopic regime between isolated atoms and molecules in bulk matter.

The 1990s have seen a steady increase in Asian students in North American institutions of higher learning. In this work, four major classroom communication patterns - total integration, conditional integration, marginal participation, and silent observation - are identified.
