The aromaticity of C36X cations and anions are interpreted.

对C36X的阳离子和阴离子的芳香性进行了解释。

In this paper we address the question of the transition between autoionization that prevails in small molecules, and delayed ionization occurring in larger molecules or clusters. This transition is illustrated by autoionization of Na2 Rydberg states on one hand, delayed ionization in fullerene C60, and delayed detachment in small cluster anions on the other hand.

本文通过Na2的里德堡态的自电离，富勒烯C60的延迟电离，阴离子小团簇的延迟解离研究了在小分子中起主导作用的自电离和在大分子以及团簇中出现的延迟电离之间的转变过程。

Objective:To introduce a new rapid detennination method of cations and anions in dialysis solution for artificial kidney .

目的：建立一种快速测定人工肾透析液中的阳离子Na~+、K~+、Ca~(2+)、Mg~(2+)，和阴离子Ac~-、Cl~-的新方法。

The electrode doped with phthalocyanine tiv displays fast response time and high selectivity for salicylate over common anions. The resulting electrode has been successfully used for determination of salicylate in pharmaceutical preprations and urine samples.

以锡酞菁为载体，制得了性能优良的水杨酸根离子选择电极，电极对水杨酸根有较高的选择性及较短的响应时间，并实际应用于药物及尿样的分析。

In addition, in-situ infrared spectroscopy provides the information about the nature of the surface acid and base sites. For example, Lewis acid and base sites on metal oxides are coordinatively unsaturated metal cations and oxygen anions, respectively, while Brinsted acid and base sites are the hydroxyl groups on the surface.

结合原位红外光谱，还能够详细地了解表面酸碱中心的性质：金属氧化物表面的Lewis酸中心和碱中心分别是表面配位不饱和的金属离子和氧负离子， Brinsted酸中心和碱中心则是金属氧化物表面的羟基。

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。
