空心微珠表面处理对发泡效果的影响

特种铸造及有色合金 1996年第4期16卷 12-14页

作者：吴炳尧颜肖龙华翔李子全东南大学

实验研究了作为发泡剂的空心微珠经表面处理后对改善与铝液的润湿性，提高发泡铝合金空隙率和空隙均匀度的作用。实验结果表明：与未经表面处理相比，经表面处理的空心微珠容易在铝液中弥散分布，且发泡时间延长。发泡工艺更便于控制。... 详细信息

实验研究了作为发泡剂的空心微珠经表面处理后对改善与铝液的润湿性，提高发泡铝合金空隙率和空隙均匀度的作用。实验结果表明：与未经表面处理相比，经表面处理的空心微珠容易在铝液中弥散分布，且发泡时间延长。发泡工艺更便于控制。空隙大小及分布的均匀性改善。空隙率由６０％提高到６８％（经碳酸钠浸泡活化处理）和７２％（经表面镀镍）

本文基于可持续生计框架构建了家庭脆弱性评估指标体系,利用宜昌市入户调查数据,对灾害易发地区灾害发生频率高和发生频率低的两类家庭的脆弱性进行了实证比较分析。结果表明:两类家庭的脆弱性均处于中高水平,这与两类家庭自然资产存量较低有很大关系,比较而言,灾害发生频率低的家庭所拥有的物资资产、社会资产和人力资产水平均高于灾害发生频率高的家庭,而金融资产则刚好相反,由此说明在面临不同程度的灾害风险时,不同类型家庭在生计策略的选择上会有所不同,而这种生计策略的差异性则进一步加剧了灾害发生频率高家庭的脆弱性。

目的:研究远近配穴法针刺对实验性偏头痛大鼠模型血浆中CGRP及ET-1浓度的影响。方法:皮下注射硝酸甘油注射剂造成实验性偏头痛大鼠模型,经针刺治疗后,采用放射免疫法测定各组大鼠血中降钙素基因相关肽(CGRP)、内皮素-1(ET-1)的含量变化。结果:远近配穴法针刺可以显著降低模型大鼠血浆CGRP含量,显著升高ET-1含量。结论:提示远近配穴法针刺实验性偏头痛大鼠模型,可能通过血管神经内分泌机制控制偏头痛发作。

利用对湖北鄂州、黄石、仙桃三市的调查数据,分析了农村育龄妇女生育性别偏好现状及其影响因素。研究表明,农村育龄妇女仍存在一定的男孩偏好;育龄妇女的文化程度和"传统文化"为性别偏好两大主要影响因素;育龄妇女文化程度越高越不会具有男孩偏好;受"传统文化"影响越深的育龄妇女越具有强烈的男孩偏好。据此,从弱化生育性别偏好角度探讨了治理出生性别比偏高的对策。
