目的利用心脏彩超评估左心室前负荷变化对左心收缩舒张功能的影响。方法选取青海红十字医院2014年1月至2014年12月的80例肾功能不全患者进行回顾性研究,根据透析后,体重差异大小分为2组,其中A组差异g(35例);B组差异>2.5 kg(45例)。在进行1次血液透析前后,分别利用心脏彩超测量所有患者的左室射血分数(LVEF)、舒张早期最大流速(E)、舒张晚期最大流速(A)、E/A、左室舒张末期内径(LVEDD)和左室收缩末期内径(LVESD)。结果 A组患者透析前后各项指标无明显变化,差异无统计学意义(P均>0.05)。B组透析后较A组二尖瓣血流频谱E峰明显降低,A峰明显升高,E/A明显降低,差异有统计学意义(P均<0.05)。结论心脏彩超评估左心室前负荷对左心收缩舒张功能的影响时,若前负荷变化达到一定程度会明显影响左心舒张功能,而对左心收缩功能无明显影响。

针对喷涂机器人在大曲率组合曲面的面片上喷枪轨迹间的组合与连接问题,结合曲面拟合理论与喷枪建模方法,建立喷枪轨迹优化模型,提出一种满足大曲率组合曲面上喷枪轨迹首尾衔接的算法程序。首先,基于曲面拟合理论将大曲率组合曲面转换为自然二次曲面面片组合,建立涂层增长模型,对组合曲面上不同类型自然二次曲面面片交界处的喷枪轨迹进行优化;其次,基于该模型运用交换子和交换序列的思想,设计出实现喷涂大曲率组合曲面的喷枪轨迹组合与连接的新算法,并编写相应的算法程序,实现喷涂轨迹的全局优化;最后,通过某一种汽车外壳的喷涂实验,验证了模型的有效性和算法程序的可行性,实现了对大曲率组合曲面的连续性喷涂。

本文剖析中国古代神话中的天文学知识,指出“盘古开天地”表现了古人对宇宙起源演变的认识,它与基督教文明中的“创世纪”神话有质的不同;女娲炼石补天的故事反映了古人根深蒂固的固体天壳观念,“断鳌足以立四极”的说法以神话方式弥补了盖天说的漏洞,共工撞不周山的传说为天体运行机制提供了一种直观解释;《灵宪》中的“嫦娥奔月”传说表现了人们对月食特征的认识;蒲松龄的《聊斋志异》中的《雷曹》篇,则以古代的天文学知识为依据,展现了古人对天穹星辰的绮思。早期神话的创作者以神话的方式来解释自然,后期神话的创作者则借助于已有的科学知识构建故事。审视神话传说中的天文学知识,既可以藉此了解古代的天文学,也可以对神话本身有更深刻的理解。
