Nuclear analysis (mainly neutron activation analysis) is a very powerful technology in elemental anaysis of aerosol with its low detection limit, high accuracy, and the unique advantage of non-destruction of the samples.
核分析技术 (尤其是中子活化分析 )以其检测限低、精密度高、不破坏样品等优点成为气溶胶元素分析的最有效手段之一。
The progress and present status of nuclear analysis in CIAENAL are briefly described.
本文简介中国原子能科学研究院核分析实验室（ＣＩＡＥＮＡＬ）的核分析研究进展和现状，重点介绍活化分析、加速器质谱、核固体径迹探测器、离子束分析和核效应研究。
Methods Immunohistochemical SP method was used to detected c-erbB-2 expression,lymph node metastasis and karyokinesis of cancer cells in breast infiltrating ductal carcinoma.
结果c-erbB-2阳性表达主要分布在肿瘤细胞的胞膜上;随着c-erbB-2表达强度的降低,肿瘤淋巴结转移率呈减少的趋势;肿瘤组织中细胞的核分裂数目随着c-erbB-2的表达强度增加而增多。
Objective To evaluate the efficacy of neoadjuvant chemotherapy (NAC) with nedaplatin, ifosfamide and peplomycin (SIP) for patients with locally advanced squamous cell carcinoma of cervix, and to determine whether or not the mitotic index and the Ki 67 labeling index (LI) obtained from biopsy specimens were useful as predictors of NAC response.
目的 :探讨宫颈鳞状上皮癌化疗效果与组织标本中的核分裂数、 Ki- 6 7及血清 SCC值的关系。
The expression and distribution of necrosis, mitosis and apoptosis were observed in.
术后病理切片行HE染色或部分TUNEL及PCNA染色,观察照射组和未照射组各25例的直肠癌坏死、核分裂和凋亡等病理变化。
