许多学者提出重金属连续萃取法(sequential chemical extractions， SCE)研究重金属存在型态大多忽略和磷酸盐之相关性，本研究拟提出适当的连续萃取步骤，探讨中性及碱性污染土壤中重金属与磷存在型态的分布及其相关性，并探讨用盐酸清洗此等土壤时，其可能移除重金属之型态及部份植物养分成份被移除的程度。

Results: The autofluorescence of M. furfur and M. japonica standard trainsrespectively in 4th and 6th day are stronger than that in other days, andautofluorescence of colonies become weaker in an hour. Theautofluorescence of Malassezia colonies put in 3% glutaraldehyde, pH4.0HCL, 1280μg/mL and 64μg/mL fluconazol solution, 0.3% methylene blueseparately get stronger, and that in 10% KOH get stronger at beginning thenbecome weaker 2 days later. C. albicans, S. schenchii, T. rubrum, T.tonsurans, A. terreus, A. fumigatus cultured on SDA all haveautofluorescence, and which are weaker than that of Malassezia.

结果：糠秕马拉色菌和日本马拉色菌2株标准株的自发荧光强度分别在培养第4和8天时最强，菌落的自发荧光在1小时内逐渐减弱；3％戊二醛溶液、pH4.0盐酸溶液、1280μg／mL和64μg／mL氟康唑溶液、3％美蓝溶液处理后马拉色菌自发荧光都增强，10％氢氧化钾溶液中的马拉色菌在开始时荧光增强，2天后减弱；白念珠菌、申克孢子丝菌、红色毛癣菌、断发毛癣菌、土曲霉、烟曲霉等在培养条件下有自发荧光，但都较马拉色菌弱。

To explore the possibility of early and rapid diagnosis of mycosisby detecting the fungal autofluorescence. Methods: To culture M. furfur and M. japonica standard strains on Dixonmedium at 32℃, and to study the autofluorescence of colonies in 2nd, 4th, 6th, 8th, 10th day under Laser Scanning Confocal Microscopy (LeicaTCS-SP2 LSCM). To study the variation of autofluorescence whenMalassezia colonies were put in 3% glutaraldehyde, pH4.0 HCL, 10% KOH, fluconazol solution, 0.3% methylene blue separately. To detect theautofluorescence of C. albicans, S. schenchii, T. rubrum, T. tonsurans, A.terreus, A. fumigatus cultured on Sabouraud dextrose agar.

选用糠秕马拉色菌和日本马拉色菌2株标准菌，接种在Dixon培养基32℃培养，分别在培养的第2、4、6、8、10天挑取菌落放在TCS-SP2型激光扫描共聚焦显微镜(Leica TCS-SP2 LSCM)下观察、测定其自发荧光；分别用3％戊二醛溶液、pH4.0盐酸溶液、10％氢氧化钾溶液、1280μg／mL和64μg／mL氟康唑溶液、0.3％美蓝溶液处理后观察马拉色菌自发荧光的变化；选择白念珠菌、申克孢子丝菌、红色毛癣菌、断发毛癣菌、土曲霉、烟曲霉等用沙堡葡萄糖琼脂培养后观察其自发荧光的特点。
