The origin and spread of the Chinese batik have always been a controversial issue in the field of Chinese dyeing and waving historiography. The systemic analysis was carried out by the methods of textile archaeology and literature research in this paper. Conclusions have been made as follows: there were two models in the origin of Chinese batik. One, such as the Central Plains area, was the type of external afference. Another model, such as the south-western ethnic areas, was the type of generating from the inside of the area. The transmutation of batik in Central Plain areas have passed through three stages: introduction from the Eastern Han Dynasty to the Northern and Southern Dynasties, mass acceptance during the Sui Dynasty, Tang Dynasty and Five Dynasties, obsolescence during the Two Song Dynasties. From the perspectives of the reason, the rapid disappearance of batik in the Central Plains areas were caused by the special internal and external environment and the development trend of dyeing technology of the Song Dynasty.

Posture Adjustment

A bioinspired jumping robot has a strong ability to overcome obstacles. It can be applied to the occasion with complex and changeable environment, such as detection of planet surface, postdisaster relief, and military reconnaissance. So the bioinspired jumping robot has broad application prospect. The jumping process of the robot can be divided into three stages: takeoff, air posture adjustment, and landing buffer. The motivation of this review is to investigate the research results of the most published bioinspired jumping robots for these three stages. Then, the movement performance of the bioinspired jumping robots is analyzed and compared quantitatively. Then, the limitation of the research on bioinspired jumping robots is discussed, such as the research on the mechanism of biological motion is not thorough enough, the research method about structural design, material applications, and control are still traditional, and energy utilization is low, which make the robots far from practical applications. Finally, the development trend is summarized. This review provides a reference for further research of bioinspired jumping robots.

History Of

In this paper, we explore the historical background and the semantic underpinnings of a central, if marginally treated, metaphor of enlightenment and transmission in Chan discourse, “silent accord” 默契. It features centrally in Essentials of the Transmission of Mind 傳心法要, a text that gathers the teachings of Chan master Huangbo Xiyun (d. ca. 850), a major Tang dynasty figure. “Silent accord” is related to the concept of mind-to-mind transmission, which lies at the very core of Chan Buddhist self-understanding. However, Chan historiography has shown that this self-understanding was partially a product of the Song dynasty lineage records, historically retroactive syncretic constructs produced by monks and literati as efforts towards doctrinal and political recognition and orthodoxy. There are thus lacunae in the history of Chan thought opened up by the retrospective fictions of Song dynasty, and a lack of reliable, dateable documents from the preceding Tang dynasty era, possibly fraught with later additions. We situate the metaphor “silent accord” in the history of Chan thought by searching for its origins, mapping its functions in Chan literature, arguing for its influence and thereby its role in helping to bridge the 9th century gap.

The Grand Canal

In the long history of the feudal society of China, Kaifeng played a vital role. During the Northern Song Dynasty, Kaifeng became a worldwide metropolis. The important reason was that the Grand Canal, which was excavated during the Sui Dynasty, became the main transportation artery for the political and military center of the north and the economic center of the south. Furthermore, Kaifeng was located at the center of the Grand Canal, which made it the capital of the later Northern Song Dynasty. The Northern Song Dynasty was called “the canal-centered era.” The development of the canal caused a series of major changes in the society of the Northern Song Dynasty that were different from the previous ones, which directly led to the transportation revolution, and in turn, promoted the commercial revolution and the urbanization of Kaifeng. The development of commerce contributed to the agricultural and money revolutions. After the Northern Song Dynasty, the political center moved to the south. During the Yuan Dynasty, the excavation of the Grand Canal made it so that water transport did not have to pass through the Central Plains. The relocation of the political center and the change in the canal route made Kaifeng lose the value of connecting the north and south, resulting in the long-time fall of the Bianhe River. Kaifeng, which had prospered for more than 100 years, declined gradually, and by the end of the Qing Dynasty, it became a common town in the Central Plains. In ancient China, the rise and fall of cities and regions were closely related to the canal, and the relationship between Kaifeng and the Grand Canal was typical. The history may provide some inspiration for the increasingly severe urban and regional sustainable development issues in contemporary times.

To study the wake development characteristics of wind farms in complex terrains, two different types of Light Detection and Ranging (LiDAR) were used to conduct the field measurements in a mountain wind farm in Hebei Province, China. Under two different incoming wake conditions, the influence of wind shear, terrain and incoming wind characteristics on the development trend of wake was analyzed. The results showed that the existence of wind shear effect causes asymmetric distribution of wind speed in the wake region. The relief of the terrain behind the turbine indicated a subsidence of the wake centerline, which had a linear relationship with the topography altitudes. The wake recovery rates were calculated, which comprehensively validated the conclusion that the wake recovery rate is determined by both the incoming wind turbulence intensity in the wake and the magnitude of the wind speed.
