本文提供了从亚地中海地区放牧地上取得的横向变化(区别于随时间变化的纵向变化,译者注)的土壤流失数据.改进过的Gerlach水槽用来测量细沟侵蚀和细沟间侵蚀.为了找到精度较高的估算土壤侵蚀的概率抽样方法,对不同数量和不同宽度的小区试用了随机抽样、系统抽样、分层随机抽样以及成串抽样四种抽样技术.如果分细沟和细沟间两个次总体进行抽样,“随机”和“分层随机”法给出几乎相同的标准误差;成串抽样产生的误差较大,该法基本无效;系统抽样法,虽然可以选择大小比较经济合算,有更高精度的样本,但其可靠性很大程度上依赖于试验地上细沟的数量.如果只对细沟间侵蚀次总体抽样,而对细沟侵蚀量实测,可取得最小的标准误差.这样,上述四种抽样法都获得相同的精度.

为了查明造山带二辉橄榄岩与碱性熔岩中超镁铁质捕虏体之间硫含量的系统差异,本文把全岩硫地球化学与反射光显微观察相结合,对法国中央地块晚第三纪碱性玄武岩中的40个Ⅰ型尖晶石二辉橄榄岩捕虏体进行了研究。分析结果表明,不管岩石结构和(或)岩石成分如何,硫含量均变化于0～90×10^(-6),且大部分S<60×10^(-6)。与造山带尖晶石二辉橄榄岩岩体中相似岩石以及MORB(大洋中脊玄武岩)地幔源区(所计算平均硫含量为300×10^(-6))相比,尖晶石二辉橄榄岩捕虏体强烈亏损了硫。显微观察显示:幔源固体硫化物在次生氧化水合作用过程中,将发生硫的丢失。该蚀变似乎不受玄武岩母岩的影响,而可能与后期大气降水的循环有关。由此推断,除包裹在块状玄武质熔岩流中的某些样品外,几乎以前分析的所有大陆玄武岩中尖晶石二辉橄榄岩捕虏体的硫含量都不能代表上地幔的硫含量。

Chinese journal of Cancer Research 2002年第2期14卷 79-83页

Objective: To survey the role of protein tyrosine kinases (pTKs) in the pathogenesis of several hematopoietic malignancies. Methods: By reviewing the published laboratory and clinical studies on pTK-related oncoproteins and their causative role in some leukemias and lymphomas. Results: protein tyrosine kinases are key participants in signal transduction pathways that regulate cellular growth, activation and differentiations. Aberrant pTK activity resulting from gene mutation (often accompanying chromosome translocation) plays an etiologic role in several clonal hematopoietic malignancies. For example, the pTK product of the BCR-ABL fusion gene resulting from the t (9; 22) translocation exhibits several fold higher tyrosine kinase activity than the product of the ABL gene. Evidence suggests that the BCR-ABL oncoprotein alone is sufficient to case chronic myelogenous leukemia (CML) and other ph positive acute leukemia. pTK over-activity resulting from chromosomal translocations creating TEL-ABL, TEL-jAK2 and TEL-pDGFRβ fusion proteins plays an important role in the pathogenesis of other types of leukemia. Another example occurs in anaplastic large cell lymphoma (ALCL). Experimental and clinical evidences indicate that translocations involving ALK gene on chromosome 2p23, most commonly resulting in an NpM-ALK fusion oncogene, result in constitutive activation of ALK and cause ALCL. This group of lymphomas is now named ALK positive lymphoma or ALKoma. Conclusion: Genetic lesions creating aberrant fusion proteins that result in excessive pTK activity are increasingly being recognized as central to the pathogenesis of hemotopoietic malignancies. These chimeric pTK molecules represent attractive disease-specific targets against which new classes therapeutic agents are being developed.
