PRELIMINARY STUDY ON RETRO-REFLECTIVE COATED PAPER BASED ON MICROGLASS BEADS

INTRODUCTIONThe micro-glass bead[1-2] is a new kind of silicate material, with good properties of chemical stability, mechanical strength as well as electro-resistance. When its diameter is below 0.08mm and the reflective index is in the range of 1.9~2.1, retro-reflective characteristics can be achieved. When a beam of ray from any direction irradiates the surface of the micro-glass beads, it can be converged at the special reflective layer consisted of focuses of micro-glass beads, owing …     

活化链烷

链烷是天然烃类(碳氢化合物)组成的一大家族.它们在自然界中储量如此丰富,因而工业界早就对它们产生兴趣并视之为合成许多化合物和燃料的一种可能原料.一些最有名的链烷是石蜡、丙烷和甲烷.地壳中含有丰富的甲烷,其中一部分正被用作天然气燃料.同时工业上也通过复杂而昂贵的高温高压     

STABILITY CRITERIA FOR A CLASS OF UNCERTAINSYSTEMS WITH TIME—DELAY

Some stability criteria are obtained for a class of uncertain systems with time-delay usingLyapunov functional and analytic techniques. It is easy to check the criteria by making use of theboundedness of the uncertainties.     

防治心脏病的好消息

位于旧金山的加州大学医学院和太平洋长老会医疗中心一位说话温和的年轻研究员迪安·奥尼什医生(Dean Ornish)曾征集过心脏病患者实验一种治疗心脏病的新方法。更新的,不那样激烈的医疗技术也一点没能改变奥尼什的想法。冠状血管成形术中用气胀导管在阻塞的动脉中充气来把血管冲开.“但用同样方法疏通的第三条冠状动脉6个月后又阻塞了.”奥尼什指出。另一种决择,即用降胆固醇药物,虽然对有些病例有效,但是代价昂贵。用这类药物可增加患者的存活机会,但这些药物对有些人可能有副作用. “用这些处置方法,”奥尼什说,“我们经常是解决一些问题又引出另一些问题。我想从心脏病的成因上来解决问题。     

Radar Imaging Based on Iterative Algorithms

It has long been realized that the problem of radar imaging is a special case of image reconstruction in which the data are incomplete and noisy. In other fields, iterative reconstruction algorithms have been used successfully to improve the image quality. This paper studies the application of iterative algorithms in radar imaging. A discrete model is first derived, and the iterative algorithms are then adapted to radar imaging. Although such algorithms are usually time consuming, this paper shows that, if the algorithms are appropriately simplified, it is possible to realize them even in real time. The efficiency of iterative algorithms is shown through computer simulations.
