中文摘要:构造了百合鳞片的生长机与可视化模型,并根据鳞片轮生抱合形成鳞茎的生长机理,构建鳞茎生长的可视化模拟系统。鳞片视为向线生长的生长趋势,每生长一小段就向中心茎秆偏转一定角度;鳞片采用四边形图元绘制的双半椭圆台进行可视化建模,其中截面是月牙形,由两个长半轴相等短半轴不相等的半椭圆围合而成。结果表明该系统能形象地模拟百合鳞茎的生长与抱合过程。

Abstract:Growth mechanism and visualization model of lily scale was developed. According to growth mechanism of scales whirling and packing, the system of bulblet growth and visualization was constituted. The scales’ growth was regarded as linear growth trend, when growing a little elements, the scale deflected a certain angle to center-stem. Scales’ visualization model was developed by employing quadrilateral picture element drawing double-semi-elliptical truncated cone. The section drawing of scale was crescent, which was composed of two semi-ellipses of identical semi-major axis and unequal-semi-minor axis. The result shows that this system can simulate livingly lily bulblet vegetation process of whirling and packing.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
