| | ZhengKaungmycin is an antitumor antibiotic scroened out in China. Its physical and chemical properties are very similar to those of bleomycin (BLM).When ~(57)Co-ZhengKaungmyoin (A_2+B_2 mixture and A_5) was incorporated into CaEs-17 cell line derived from human esophageal carcinoma, an autoradiograph showed that ~(57)Co-ZhengKaungmycin was incorporated into the nucleus, very little into the nucleoli and none at all into the cytoplasm. The results were consistent with the observations that there were specifi... | | 我国自行筛选的抗肿瘤抗菌素——争光霉素与博莱霉素的理化性质基本相同。~(57)Co-争光霉素A_2+B_2混合品和A_5纯品参人人食管鳞癌细胞株CaEs-17的放射自显影图表明~(57)Co-争光霉素(混合品和A_5)参人到CaEs-17细胞核中,核仁参入很少,胞质不参入。从而在细胞内定位方面说明了争光霉素与DNA结合的特异性。这和博莱霉素与DNA的特异性结合、并与DNA相互作用、而不与rRNA、tRNA、白蛋白结合和作用的结果是一致的。通过~(14)C-TdR与~(57)Co-争光霉素同时参入及先后参入的双标记放射自显影图和显微分光光度计对标记和未标记细胞DNA相对含量测定等方法,证实了~(57)Co-争光霉素(混合品和A_5)参入到带有G_1/G_0期DNA含量的CaEs-17细胞中。 | | 文摘来源 | | The multiple detection method has been used for over twenty years. But not everybody has a correct and deep understanding to this method daily used in their work. For what reason can the characteristic curve be drawn from a cosine curve? Whether or not will the length of the multiple detectors give effect to it? What roles will the base length play in multiple detection?Everybody couldn't give an answer and explain them clearly. In this paper, the author tries to make clear these problems mentioned above an... | | 组合检波已经使用了二十多年,可是,对于这种天天使用的方法并非人人都能正确理解。组合检波的特性曲线为什么可以用一条余弦曲线来制作?组合距大小是否会影响特性曲线?基距长短在组合检波中起什么作用?这些问题并非人人都能说得清楚。本文就是试图对以上关于组合检波的基本问题加以说明。 | | 文摘来源 | | Seismic reflection technology, although nearly sixty years, is still evolving quite rapidly. The purpose of this paper is to present a broad review of how this evolution took place in the past, what factors caused it and, based on its recent development, what canbe expected in the near future. There is nothing in this paper which is not generally known and, if some of you feel disappointed, I apologize to them. But my goal is to give to those involved in seismic reflection exploration a better grasp of how... | | 地震反射法虽然已经过了约六十个春秋,仍然正在飞速演变。本文的目的是对这些演变的发生,引起演变的因素,近来的发展情况,以及将来会发生什么变化进行广泛的评论。文中尽是些人人皆知的事实,如果你们中有些人感到失望,我先在此致歉。但是,我的目的是使那些与地震反射勘探有关的人对我们如何发展到当前这种状况有更好地了解。方法相当复杂,对任何人来说,不剖析历史就不能回答。计划在三个方面论述反射地震法,即数据采集,数据处理和解释中的方法和仪器等。其他技术,如电子学、记录、数字计算机等的演变对油气地震反射勘探发展的影响也作了清楚的说明。一方面进行广泛的历史回顾,另一方面则逐渐把评论的焦点集中于最近几年,以期给出一幅目前情况的清晰图画。据此试图洞察未来重大的发展,并且指出需要解决的最重要的问题可能出现在什么地方。 | | 文摘来源 | |   | | << 更多相关文摘 |
