Presents the microstructure evolution in aluminum a nd copper after deformation by cold rolling in the strain range of 10 to 50%red uction using TEM and points out three types of dislocation structures are typica l and two of them are common for both materials and these two common types are f ound in non-cube grains and can be distinguished by crystallographic orientatio n of dislocation boundaries in the grains and the third type of structure is obs erved in cube grains, and concludes that grain orientation is important in deter mining the structure type but some other metallurgical parameters also have a ro le to play.

采用TEM对冷轧多晶铜与多晶铝的形变显微组织演变进行了对比研究。结果发现：多晶铜及多晶铝形变显微组织中均含有三类典型的位错结构类型，其中的两种结构特征在两种材料中是相似的，这两种类型结构存在于非立方取向晶粒，可通过晶粒中位错边界的晶体学取向加以区别，另一类型结构存在于立方取向晶粒；晶粒的晶体学取向决定了其形变显微组织类型，但其它冶金学因素对显微组织也有影响。

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
