Then we studied the double phase transition behavior of three-layer nanostructures with double thermoresponsive shells. Successive RAFT polymerization of NIPAM and 2-ethyl methacrylate or DMA and NIPAM were conducted using PS macroRAFT agent. The PS-b-PNIPAM-b-PDMA and PS-b-PDMA-b- PNIPAM triblock copolymers can self-assemble into PS-core micelles, which possess a three layer \'onion-like\' structure, with PDMA and PNIPAM blocks forming the inner layers or outer coronas.

另外我们还合成了含有PS、PNIPAM、PDMA三嵌段聚合物，也利用芘标记的方法可以得出：对于PS-b-PNIPAM-(来源：A29BC论文网www.abclunwen.com)b-PDMA胶束存在两个明显的相转变过程，第一个是内层的PNIPAM这一个很宽的温度(20-32℃)的塌缩过程，接着是32-50℃下的PNIPAM和PDMA的混合塌缩或聚集过程。

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。
