阴电的

A blue filter. He then projected each of the three positives, with the three images superimposed, onto a white screen with each image projected through the same filter he had used in making the transparency. Maxwell was lucky in his demonstration; years later it was pointed out that the collodion process

片，用绿、红、蓝光来穿透幻灯片，之后再将这三种颜色重叠并投射在一张白色的萤幕上，在明确度方面使用相同方式在每张投影片上，马克斯韦尔在他的示范上是幸运作成功，但是几年之后，这种方式被修正，因为阴电性对红光是迟钝的但是对苏格兰格子呢的红色部分是敏感的。

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。
