“技艺”之于建筑，始终是建筑学讨论的重要话题。但绝非从字面意义理解的“技艺”，在当代的建筑创作及每个建筑师的不同实践作品中，“技艺”包含着越来越广泛与深刻的含义。正如本期报道的由崔愷院士团队设计的“荣成市少年宫”——一个始于“童趣”、终于“砼趣”的独特建筑，亦或一种海滨城市中的独特风景。

在这个独特建筑或人造风景中，所显现出的均是对自然、环境、人、城市的回应。“技艺”首先是源于对海边山体、丘陵中礁石及其孔洞抽象化感知的清水混凝土斜面、曲拱相贯的空间营造，既是混凝土拱券结构的恰当性能表现，也是可闻导风啸声、可观湖海、可遇野花小径的童趣空间。“技艺”也是建筑师与工程师融合了拱、穹或壳、片拱、水滴柱、框架结构，以及双层模板技术、参数化施工、混凝土裂缝的控制、分期浇筑控制品质等高水平施工技术的高超建构。“技艺”更是以孩童之心营造海浪击石如钟、水底投影如灯的场所空间，当然穿越其中的风、光、声也是超越感知之上的科学性自然营造，真正在等待青少年去理解和探索。荣成市少年宫是崔总一贯秉持的“本土设计”理念的又一次创新之作，鼓舞着我们每一位建筑师。

“Technique and art”of architecture has always been an important topic in architec—tural discussion.But it beyonds its literal meaning.In contemporary architectural creation and different practical works of each architect,it contains more and more extensive and profound meaning.Rongc—heng Youth Activity Center designed by Ac—ademician Cui Kai's team,which reported in this issue,is not only a special building that starts with "children's naiveness" and ends with "concrete interest",but also a unique landscape in a coastal city.

What appears here is the response to nature,environment,people and cities.“Technique and art”first comes from space construction shaped by as—cast finish con—crete slope and crossed arches.It is not only the appropriate performance of concrete arch structure,but also a children's naive—ness space where you can hear the wind howling,observe the lake and sea,and meet the path of wild flowers.Then,it is also a superb construction in which architects and engineers integrate arch,dome or shell,slice arch,water drop column,frame structure,as well as high—level construction technologies such as double—layer formwork technology,parametric construction,concrete crack control,phased pouring control quality and so on.Furthermore,it creates a space where the waves hit the stone like a bell and the underwater projection like a lamp with the heart of children.Through the wind,light and sound,it is also a scientific and natural creation beyond perception,which is really waiting for teenagers to understand and explore.Rongcheng Youth Activity Center is another innovative work of the concept of "land based rationalism" always adhered by Mr.Cui,which inspires every architect.
