摘要：The core ideas of Constructivism were mentioned by John Dewey, so it is not a new idea. Constructivism claims that each learner constructs knowledge individually and socially. The ＂glue＂ that holds the constructs together is meaning. Knowledge is not ＂out there＂, as the realist philosophers such as Plato claimed. Knowledge is always an interpretation of reality, not a ＂true＂ representation of it. Thus, the aims of this study are： （1） to shed the light on the schools of constructivism, and （2） to clarify the principles of the constructivist learning in general and in language teaching in particular.

摘要：Tsangyang Gyatso＇s poems were widely circulated and still enjoy popularity. He was an influential living Buddha （Renpoche） in Tibetan Buddhism and a talented and legendary historical figure. Nowadays, more and more scholars, poets and translators have devoted to the study of his works. Here we will focus on discussing the English translation of his poems and their value. We analyze texts of the Tsangyang Gyatso＇s Poems （Chinese-English） and seek to further study the translation principles such as ＂retaining truth, seeking goodness and preserving beauty＂. By doing this, we strive to improve the quality of translation, give consideration to the construction of the four elements such as poetic meaning, emotion, tone and intention, to enable the reader to achieve the senses and the acquisition of images, to provide more perfect translation in the ＂Tsangyang Gyatso Vogue＂, to promote the dissemination and sharing of Tibetan culture and to inject new vitality.

摘要：Water is an intelligential element in *** the planning and design of waterscape in Zixinyuan residential area as an example,the design model and its feasibility are discussed in terms of the design of waterscape and management system of water in urban residential *** is considered that a good waterscape should satisfy two aspects:firstly,it should display a fine visual effect and profound artistic conception;secondly,the problems such as self-cleaning,recycling,and reuse of water should be solved by the management system to save water *** combination of the two aspects can inspire the ecological function of *** the waterscape and urban cultural environment can be in a harmonious coexistence.

摘要：Organization forms, components, spatial scales and configuration principles of settlement landscapes in ancient Xianshi Town, Zigong City of Sichuan Province were investigated and analyzed. Specifically, overall layout and organization forms were elaborated; spatial components of settlement landscapes were discussed from the perspectives of exterior open landscape space, interior enclosed landscape space, and transitional landscape space; factors influencing the scale of streets, lanes and buildings were introduced, spatial scales of major streets and buildings in the town were calculated; and finally configuration principles of settlement landscapes in the town were proposed from the perspectives of rhythm and sense, symmetry and balance, diversity and unification. And it was concluded that settlement landscapes in ancient Xianshi Town have achieved the harmony between human and nature in terms of both organization of overall spaces and design of partial spaces.

摘要：Biochar is a solid material obtained from the carbonization of biomass. Biochar is used on agricultural lands as a soil amendment to improve the fertility of the soils. Currently the most common method of producing biochar is through biochar stoves. There are two basic stove operations in the production of biochar. The first type of stove produces biochar by direct combustion of biomass. Here biomass is burnt inside a chamber in an oxygen limited environment. The resulting residue is the bio-char. The second type involves burning the biomass in one chamber and housing the biomass to be charred in the annular portion of an outer chamber. Heat is transferred from the burning fuel on the inner chamber to the material to be charred in the outer chamber. While the process of biochar production in these stoves is known, the basic principles of the stove design are not readily available. The design methodology for both the types was developed from first principles. Prototypes of both types were constructed based on the design developed and tested. The paper lists the basic principles in the design of biochar stoves and the test results.
