碳硅石

In addition, native gold and Si-bearing native copper and SiC that is an indicator of high pressure were recognized in picrites. This is the first documented case of the native gold and native copper enclosed in olivine phenocrystals, which will play a key role in studying the compositions of mantle plume.

此外，还对两个苦橄岩进行了重矿物分选，分选出高纯度的自然金和含Si的自然铜以及高压指示矿物碳硅石，并在薄片中发现了自然金和自然铜被包裹在橄榄石斑晶的现象，这是世界上首次在橄榄石斑晶中发现自然金和自然铜，对进一步研究地幔柱的物质组成具有要的科学意义。

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。
