目前,我国防护林的建设,计划经济色彩相当浓厚,表现在:投资没有预算;资金使用上存在平均主义;工程实施缺乏竞争等.为了加快工程的建设速度和提高建设质量,应该引入市场机制,并使之与行政手段、法律手段相结合,以保证工程建设的顺利完成. 相似文献

The exploration of the universe has captured mankind's interest since the earliest attempts to understand the sun, moon, planets, comets, and stars. The last few decades have seen explosive advances of knowledge, sparked by technological advances and by our entry into the space age. Achievements in solar system exploration, discoveries both in the Milky Way and in the farther universe, and challenges for the future are discussed. Of major concern worldwide is the need for people of goodwill in all nations to concentrate on the peaceful uses of outer space and on international collaboration. 相似文献

I am, of course, deeply aware of important contributions made by many colleagues and my friends throughout this long journey. The subject of the second section was carried out when I was in Japan and all the rest (35) has been performed in the United States of America. Since my journey into tunneling is still continuing, I do not come to any conclusions in this talk. However, I would like to point out that many high barriers exist in this world: barriers between nations, races, and creeds. Unfortunately, some barriers are thick and strong. But I hope, with determination, we will find a way to tunnel through these barriers easily and freely, to bring the world together so that everyone can share in the legacy of Alfred Nobel. 相似文献

《小逻辑》关于绝对观念的自我演绎,三大规律以及哲学的反思等观点为马克思主义所扬弃,应批判地吸收其"辩证法"的合理内核,看到黑格尔体系内在的局限。新时代马克思主义者将继续关注现实存在的人的状况,准确运用辩证法处理当前各种社会关系。 相似文献
