查询词典 helixes

A variety of structures are found to be stable, such as cylinders, undulated cylinders, lamellae with cylinders, perforated lamellae and alternating versions of the sphere in matrix structures, etc. In particular, some new morphologies, such as cylinders with alternating helixes structure and complicated hybrid network structures are found in our studies.

研究结果表明，在受限及表面场作用下出现了一系列稳定的相形态，包括柱状相、波浪柱状相、层状相和交替柱状(来源：Ae1Bd2C论文网www.abclunwen.com)相、穿孔层状相及交替分散的球状结构等，这些结构在实验和理论上都已被发现。

The key components such as drive device, feed equipment and combination roll of coal briquetting machine were improved. The bridge-type synchronous gear-drive device was designed to implement the concession of driven shaft in order to protect the costly roll. The helixes feed equipment was used to improve the plasticity of material to ensure the strength of products.

采用过桥齿轮传动实现从动型轮轴的退让，以保护价格较高的型轮部件；采用螺旋强制给料机构提高成型前物料的密度和可塑性，以保证型煤成品的强度；采用型槽与型齿对应配置的型窝，在获得同样强度的型球条件下降低成型压力，减小动力消耗。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
