脲醛胶粘剂固化早期的变化特性

胶粘剂的固化性质在使工艺规程适合于木材复合材料生产中起着决定性作用。最近,对热固性胶粘剂的研究,通过运用扭辨扭力分析技术,观察了几个不连续固化特性的例子。本文发现:在不同加热条件下,脲醛胶硬度变化曲线都表明会发生两段固化... 详细信息

胶粘剂的固化性质在使工艺规程适合于木材复合材料生产中起着决定性作用。最近,对热固性胶粘剂的研究,通过运用扭辨扭力分析技术,观察了几个不连续固化特性的例子。本文发现:在不同加热条件下,脲醛胶硬度变化曲线都表明会发生两段固化。在早期固化阶段,聚合物的硬度增加有限,在达到这个阶段结束之前,硬度会降低,而高硬度主要是在第二阶段。胶粘剂的热塑性一直保持到固化最终。这种固化特性似乎与以前有关压制碎料板过程中强度出现异常的报告相类似。

WC—Co合金真实粒度的分布

国外金属热处理 1991年第2期12卷 28-32页

作者： J.Wasen r.warren 陈良平徐启华西安空军工程学院

以二维截面上作的测量为基础采用计算机辅助的模拟法来确定工业用WC—15Co(重量％)合金的真实晶粒度。这种方法考虑了晶粒的不规则形状,从而避免了传统晶粒度分布分析中固有的不精确性。我们发现,运用这种方法获得的晶粒度分布比用理论... 详细信息

以二维截面上作的测量为基础采用计算机辅助的模拟法来确定工业用WC—15Co(重量％)合金的真实晶粒度。这种方法考虑了晶粒的不规则形状,从而避免了传统晶粒度分布分析中固有的不精确性。我们发现,运用这种方法获得的晶粒度分布比用理论晶粒生长模型预测的要宽些。

Evaluating whether hybrid zones are stable or mobile can provide novelinsights for evolution and conservation biology. Butterflies exhibit high sensitivity to envi-ronmental changes and represent an important model system for the study of hybrid zoneorigins and maintenance. Here, we review the literature exploring butterfly hybrid zones,with a special focus on their spatiotemporal dynamics and the potential mechanisms thatcould lead to their movement or stability. We then compare different lines of evidenceused to investigate hybrid zone dynamics and discuss the strengths and weaknesses ofeach approach. Our goal with this review is to reveal general conditions associated withthe stability or mobility of butterfly hybrid zones by synthesizing evidence obtained us-ing different types of data sampled across multiple regions and spatial scales. Finally, wediscuss spatiotemporal dynamics in the context of a speciation/divergence continuum, therelevance of hybrid zones for conservation biology, and recommend key topics for futureinvestigation.

背景:儿童如果发生结核病,通常会假设其传染源是生活在同一家庭的成年传染性病例。本研究应用限定性片断长度多态性分析技术(rFLP)来确定从传染源到儿童的传播。设计:收集1993年到1998年诊断的成人及儿童结核病例和他们的结核分枝杆菌培养物。通过访视和结核分枝杆菌菌株的rFLP分析来确定流行病学联系及证实家庭内传播。结果:1291名成人中有1139名(91％)和417名儿童中有65名(16％)籍培养结果证实为结核病。由于要重新收集痰标本和提取DNA的问题,仅对其中的832名成人和35名儿童进行了rFLP分析:19名(54％)儿童有家庭成员确诊为结核病,12名儿童有与其家庭成员相同的菌株。分离自儿童的29株(83％)菌株构成了社区簇的一部分,但与传染源有明确接触史者只有15株。结论:在具有传染性成人肺结核病例的家庭中,儿童患有结核病并不意味着必然是成人对儿童的传播。儿童可能是在社区也可能是在家庭中受到感染。此结果对在高发病率地区的接触者追踪及治疗策略有意义。
