幻灯片制作是《生物技术》内容的一部份。过去由于条件的限制,我们在教学中只开设黑白幻灯片的制作课。随着生物科学和电化教学的发展,黑白幻灯片已远远不能满足要求,需要彩色幻灯片才能准确地反映实验的结果和提高科研、教学质量。但是,彩色幻灯片的制作目前还只限于大、中城市中少数拥有昂贵设备的专业彩色冲洗单位,并且由于要收集一定的数量后才能开机冲印,故周期较长。不能适应教学和科研的需要。我在长期从事生物技术 Slideshow making is part of “biotechnology” content. In the past due to the conditions of the restrictions, we only set up black and white slides in teaching production class. With the development of biology and electrochemistry teaching, the black-and-white slideshow has been far from meeting the requirements, and color slides are needed to accurately reflect the experimental results and improve the quality of scientific research and teaching. However, the production of color slides is currently limited to a small number of professional color washing units in large and medium-sized cities which have expensive equipment. Since the color slides are collected after a certain amount of power is turned on, the cycle time is longer. Can not meet the needs of teaching and research. I am engaged in biotechnology for a long time
