The first newspapers were handwritten sheets which were posted in public places. The earliest recorded newspaper was started in Rome in 59 B. C.. In the 700s, the world’s first printed newspaper was developed in China. The paper was printed from carved wooden blocks and distributed among the citizens. Europe didn’t have a regularly published newspaper until 1609, when one was started in Germany. The first regularly published newspaper in the English language was printed in Amsterdam in 1620. In 1621, an English newspaper was started in London and was published weekly. The first daily English newspaper was the Daily Courant( current), which didn’t appear until March 1702. In 1690, Benjamin Harris printed the first American newspaper in Boston. The paper was called Publick (public) Occurrences, hath forreign (foreign) and domastick (domestic). The local government, however, didn’t approve of the paper and stopped its publication after the first issue. In 170

某混凝土重力坝工程包括左岸非溢流坝段、溢流坝段、右岸非溢流坝段、右岸坝肩混凝土刺墙段。最大坝高43m，坝顶全长322m，共17个坝段。该工程采用明渠导流施工。坝址以上流域面积610.5km²，属于亚热带暖湿气候区，雨量充沛，湿润温和。平均气温比较高，需要采取温控措施。其施工组织设计主要内容包括：
（1）大坝混凝土施工方案的选择。
（2）坝体的分缝分块。根据混凝土坝型、地质情况、结构布置、施工方法、浇筑能力、控温水平等因素进行综合考虑。
（3）坝体混凝土浇筑强制的确定。应满足该坝体在施工期的历年度汛高程与工程面貌。在安排坝体混凝土浇筑工程进度时，应估算施工有效工作日，分析气象因素造成的停工或影响天数，扣除法定节假日，然后再根据阶段混凝土浇筑方量拟定混凝土的月浇筑强度和日平均浇筑程度。
（4）混凝土拌合系统的位置与容量选择。
（5）混凝土运输方式与运输机械选择。
（6）运输线路与起重机轨道布置。门、塔机栈桥高程必须在导流规划确定的洪水位以上，宜稍高于坝体重心，并与供料线布置高程相协调，栈桥一般平行于坝轴线布置，栈桥墩宜部分埋入坝内。
（7）混凝土温控要求及主要温控措施。
