火箭与长征火箭的故事（征服太空之路丛书）
火箭技术是一项十分复杂的综合性技术，主要包括火箭推进技术、总体 设计技术、火箭结构技术、控制和制导技术、计划管理技术、可靠性和质量控制技术、试验技术，对导弹来说还有弹头制导和控制、突防、再人防热、 核加固和小型化等弹头技术。如今，世界各国都加快了向太空进军的步伐，把探测目标投向了更远的 地方，而对火箭的研制是其中不可缺少的一环。我们有理由相信，人类凭借自己的聪明才智，一定能够研制出更先进，飞得更远的火箭，把探测器送到 月球、火星甚至更远的地方。
Spencer's Mountain
High up on a mountain, young Clay-Boy Spencer joins his father and eight uncles to hunt the mythical white deer. What he finds on the mountainside changes his life—and marks him for a special destiny. Years later, Clay-Boy is the first in his family to get the chance to go to college; but success as an adult is much more complicated and bittersweet than the legendary success of Clay-Boy's childhood quest.A heartwarming novel of love, family, and hope, Spencer's Mountain inspired the popular television show The Waltons, which starred Richard Thomas, Andrew Duggan, and Patricia Neal, and ran for nine years between 1972 and 1981. More than fifty years after its publication, this novel still has the power to inspire and move readers all over the world.
