the first half of the twentieth century meaning in Chinese

二十世纪上半叶

This cubist vision of the world introduced a new period in the history of art and influenced all the forms of self - expression in the first half of the twentieth century : sculpture , architecture , ballet , theater design , and all the decorative arts
这种对世界的立体感开创了绘画史上的一个新时期，并影响了20世纪上半叶的自我表现的各种形式：雕塑、建筑、舞剧、舞台设计和所有的装饰艺术。
During the first half of the twentieth century , in some seemingly unrelated research fields appear the studies on science and technology communication , such as researches on science and technology communication in the science and technology study , on technology proliferation in the communication science , and communication practices on technological communication study , all of which can be regarded as the three sources of science and technology communication
摘要20世纪上半叶，在一些看起来并不相关的研究领域中，先后出现了一些有关科技传播的研究，例如科学技术学对科技传播的研究、传播学对技术扩散的研究、 “技术传播”对传播实践的研究，这些研究对科技传播学的产生和发展产生了重要作用，实际上成为科技传播学的三大源头。
