Dujiangyan irrigation system of more than 2000 years history is a symbol of originality of Chinese ancestors both in its conception
and project mode. It is still working well and benefit Chengdu Plain nowadays while other comparable water conservancy projects
of the same or later age have vanished and been forgotten. More than just a world-famous cultural heritage, it shows the harmonious
relationship between man and nature. And it also reveals us how to solve problems in the era of economic globalization, such
as the constantly silt up of the dams, the exhaustion of the energy and the crisis of the deterioration of ecosystem. The
inspirations it gives us range from technology to humanities, from economy to various aspects in social life. In a word, Dujiangyan
irrigation system demonstrates the wisdom and creativity of Chinese people and has a universal significance despite the change
of time and space.

Xu, H.-H., Wang, Y., Tang, P. & Wang, Y., May 2017. A new diminutive euphyllophyte from the Middle Devonian of West Junggar, Xinjiang, China and its evolutionary implications. Alcheringa 41, 524–531. ISSN 0311-5518.
A diminutive euphyllophyte, Douaphyton levigata gen. et sp. nov., is described from the upper Middle Devonian (Givetian) Hujiersite Formation of West Junggar, Xinjiang, China. The plant consists of more than three orders of axis branching, each axis being less than 2 mm wide. The second-order axes are short, laterally and alternately attached to the main axis. The third-order axes are paired and anisotomously divided, bearing the vegetative appendages or the fertile units. The fertile unit consists of a short recurved axis giving off up to four short pedicels along one side, each of which bears one to four pairs of terminal sporangia. Douaphyton has a three-dimensional branching system that has an intermediate form in the evolutionary context of euphyllophytes and lignophytes. It is also proposed that complex branching developed in multiple groups in the Middle Devonian.

While photogrammetry has become popular in archaeology and heritage management as an effective, low-cost method for generating detailed three-dimensional models, it remains to be established that the accuracy of model-derived measurements is sufficient for analytical purposes. Based on an expedient, in-field model processing protocol, we report preliminary results concerning the accuracy of artifact provenience information derived from photogrammetry models of excavation surfaces at the Upper Palaeolithic site of Shuidonggou Locality 2 in China. Error in model-derived provenience can range easily into the centimeter scale; accuracy in some spatial axes are significantly, but weakly, affected by the size of the sampled surface. While the observed error range is larger than thresholds proposed for Palaeolithic excavations, it is arguably acceptable in settings where the analytical demand for provenience precision is lower. We identify possible sources of error and discuss how model accuracy can be improved by additional systematic testing. 相似文献
The rise of a non-democratic China as the world ‘s second largest economy, still officially subscribing to Communism or ‘Socialism with Chinese characteristics’ as its ideology1?1 In Xi Jinping's first speech as the new Chinese leader, after assuming his position as Party Secretary at the 18th Party Congress in November 2012, he declared that, “we will ensure that our Party will remain at the core of leadership in advancing the cause of socialism with Chinese characteristics”. Xinhua report on 19 November 2012. http://www.chinadaily.com.cn/china/2012cpc/2012-11/19/content_15939817.htm. By adopting the term “Socialism with Chinese Characteristics” – zhongguo tese de shehui zhuyi, the Chinese Communist Party has argued that it has not abandoned socialism by introducing foreign capital and the opening up the Chinese economy to market forces. See for example a report on Deng Xiaoping's remarks to visiting Japanese delegation in 1984, “Build Socialism with Chinese Characteristics” People's Daily, 30 June 1984. http://english.peopledaily.com.cn/dengxp/vol3/text/c1220.html., has raised the spectre of the return of the Cold War to Asia with the United States and China on opposing sides, with China backed by Russia, its former Cold War ally. But to what extent are there historical parallels between the Cold War and the current East Asian international relations system? 相似文献
