In this paper,by simulating different indoor and outdoor experiments of the crude oils in the different weathering environment of summer and winter,and using fluorescence spectrometry,Comparison and analysis of spectra from oils of unweathered and at different weathering times are experimentalized(crude oils from Kuwait and Saudi- Arabia,which are both light crude oils),which could identify the two similar oil species,without taking into account the biological degradation,wind speed,as well as factors such as the role of the waves,and the impact of factors,then how the fingerprints will be changed in the law have been found.

本文通过模拟不同原油在室内和室外的夏、冬两季的风化实验，运用荧光光谱法，对未风化油品和不同风化时间的油品(科威特原油和沙特阿拉伯轻质原油)进行谱图对比分析，鉴别两种相似油种，在不考虑生物降解、风速以及海浪等因素的影响，找出油指纹随风化影响因素的变化规律。

ABSTRACT Objective To discuss the clinical pathologic features and differential diagnosis of mixed germ cell sex cord stromal tumorwith malignant variant of germ cell tumor Methods The clinical pathologic datum and immunophenotype were studied in the case of ovary MGCSCST with malignant variance of germ cell tumor Results The patient's genital anatomy and female phenotype were normal,karotypes was 46xx with uterogestation The tumor tissue consisted of mixed germ cells and sex cord stromal cells with evident malignancy of mixed germ cells There was no atypical structure of gonadoblastoma in tumor tissue Conclusion MGCSCSST has complex morphosis,thus,to prevent misdiagnosis,more samples should be collected and more slices be cut The patient may have prognosis malo when there are high malignant variants of mixed germ cells in tumor tissue

目的 探讨混合性生殖细胞性索间质肿瘤(mixed germ cell sex cord stromal tumor，MGCSCST)伴恶性生殖细胞肿瘤变异型的临床病理特点及鉴别诊断。方法卵巢MGCSCST伴恶性生殖细胞肿瘤变异型的病例进行临床病理特征和免疫表型分析。结果患者生殖器的解剖结构和女性表型正常，染色体组型是46xx，足月妊娠。肿瘤组织由混合性生殖细胞和性索间质肿瘤构成，混合性生殖细胞有显著的恶性特征。瘤组织中没有典型的性腺母细胞瘤结构。结论 MGCSCST有复杂的形态结构，因此更多的取材和切片可以防止误诊，当肿瘤组织中的混合性生殖细胞有高度恶性变异时，患者预后不良。卵巢肿瘤；生殖细胞性索间质肿瘤；免疫组织化学
