浓墨重彩绘“强”图——铜仁市建设经济强县纪实

面对难得的“建强”机遇,铜仁市决策层决心:冷静分析差距,勇于自加压力,争取加速发展 1999年初,省委、省政府作出建设首批经济强县的战略决策,铜仁市是列入首批建设的20个县(市、区)之一。省委、省政府明确提出,列入首批建设的经济强县,国内生产总值必须达到或超过10亿元,财政总收入必须达到或超过1亿元。 对铜仁市的经济和社会发展现状,以及铜仁市被列入首批建设经济强县行列的原因,铜仁地委、行署,特别是市委、市政府都是很清楚的。事实上,如何把铜仁市的建设经济强县工作搞好,成为摆在全市上下的一大难题。 建国以来,特别是改革开放以来,铜仁市的经济快速发展,人民生活水平不断提高,各项建设取得了令人瞩目的成就。但是,由于历史和现实,自然和社会,人文和地理等原因,

中学生延时学习判断准确性研究

本研究采用单因素（年级：初二、高二文科、高二理科）组间设计，对中学生延时学习判断进行了研究。结果表明：1.在年级因素上JOLs等级、回忆正确率和绝对准确性均存在显著差异；2.材料难度仅在高中文科水平上与JOLs等级、回忆正确率和绝对准确性均存在显著相关。

REFRACTIVE INDEX AND APPARENT DENSITY OF THE EVAPORATED FILM OF COPPER PHTHALOCYANINE

As the film thickness is an important factor in the study of evaporated films, we have been looking for a convenient and nondestructive method of film thickness measurement. The infrared interferometric method which has been used for thickness measurement of the epitaxical growth of silicon, gives the optical thickness, i.e. the product of refractive index and thickness. In order to get the refractive index of αI-

EFFECT OF INCIDENT MOLECULE BEAM DIRECTION ON THE CRYSTALLITE ORIENTATION OF THE EVAPORATED FILM OF COPPER PHTHALOCYANINE

The crystallite orientation of the evaporated film of copper phthalocyanine (PcCu) has a great effect on its electrical conduction properties. Many authors have studied the structure of the film, and obtained different results in relative strengths of X-ray diffraction peaks showing different crystallite orientations. The
