新农村建设规划用图若干问题的探讨

测绘新农村建设规划用图是现阶段测绘工作中的一项重要内容,由于该项工作起步较晚,在测绘实践中尚存在着一些问题,如现状图的精度要求、测图比例尺与成图方式的选取、测图的主要内容等。为此,对新农村建设规划用图的这些问题进行了详细的讨论。

重视过程——从王麓台画风看山水画成图的方式

过程是事物发展变化的连续性状态。具体在中国画山水科,是成图规律的总结和揭示,因此,重视过程的研究就尤为要紧。在基本过程规律把握的基础上,不同的过程时序能产生不同的图式效果,最具个性的作画过程某种程度上能直接导致一种新画风的产生。四王中,王麓台的画风无疑最具特点,而形成这种画风的关键,过程起了作用。从这一典型出发,就过程的发展、过程的环节特点及基本过程等进行描述,并宏观上提出山水画图式产生过程中两种方向性的过程模式。

Three dimensional image-based brachytherapy:evaluating the true impact on treatment outcome

Imaging is now a well established component of radiation therapy with all major imaging modalities represented and numerous examples in which these modalities have been used in treatment planning to allow increased accuracy and precision in the delivery of dose.While these developments are well established since a fairly long time for external beam radiotherapy,they are yet to be firmly established in many brachytherapy units all over the world particularly in the developing countries.We will review the basic principles of image-based brachytherapy and explore the potential clinical opportunities behind this innovative technique.
