Abstract：随着时代的不断进步,科学技术的不断发展,使得现实技术被应用得越来越广泛,地位也越发重要,在图书出版领域也是如此。正因现实技术的融入,才使得图书的纸质版本与电子版本相结合,也就达到了一种虚实结合的状态,极大程度上促使了纸质阅读的前景发展。因此就需要对现实技术进行强化,使其可以在图书出版领域发挥出更加重要的作用。此篇文章首先介绍了强化现实技术的应用模式,以及其对传统图书出版方式的创新影响,并分析了图书的出版现状及解决措施,希望可以为现实技术更好的应用奠定基础。

Abstract： 对新疆孔雀河北缘的LX02剖面湖相沉积物开展了OSL测年和孢粉记录研究。结果显示，该剖面湖相沉积自72.4ka B.P.延续到51.0 ka B.P.。这一期间，研究区为针叶、阔叶混交林植被，林下生长灌木和草本，低洼潮湿的地方生长蕨类孢子和藻类。植被的主要类型有松(Pinus)、栎(Quercus)、栗(Castanea)、榛(Corylus)、莎草(Cyperaceae)、蒿(Artemisia)、藜(Chenopodiaceae)、水龙骨科(Polypodiaceae)等，同时还含有少量的山核桃(Carya)和枫杨(Pterocarya)等亚热带的孑遗植物花粉。具体来说， 组合带Ⅰ(72.4～66.8ka B.P.)、Ⅲ(56.1～51.0ka B.P.)对应的沉积期间，研究区阔叶树花粉含量低而灌木和草本花粉含量高；组合带Ⅱ(66.8～56.1ka B.P.)对应的沉积期阔叶树花粉含量都较高，而灌木和草本花粉相对较低，揭示72.4～51.0ka B.P.研究区气候总体上呈现冷干-暖湿的气候波动特征。这与粘土矿物和地球化学特征所反映的古气候特征及其变化一致，亦与柴达木盆地东部介形类丰度特征研究、柴达木盆地东部古湖泊高湖面光释光年代学研究、北京平原区有机碳同位素研究等结果吻合较好。不过，这一气候变化规律的内部驱动机制还有待进一步深入研究。

Abstract： In order to cultivate the traffic BIM talents to meet the social needs, the "1+1" teaching mode of transportation BIM application ability is put forward in this paper on the basis of analyzing the development trend of BIM technology in the transportation industry and the current situation of the computer application course of transportation specialty. In the proposed teaching mode, the BIM modeling ability of students is developed from the aspects of alignments and structure respectively. In the teaching implementation plan, the whole teaching process is divided into four stages which are connected with each other and step by step. Through teaching methods such as CAD-BIM connection teaching, contrast teaching and project-driven comprehensive practice, students can quickly understand the advanced character of BIM technology compared with the CAD technology, master the basic skills of BIM technology and have some practical ability.

Abstract：本试验通过限饲的方法，研究饲粮不同粗蛋白质水平对肉种鸡生产性能、繁殖性能及蛋品质的影响。选取25周龄体重、产蛋率一致的肉种鸡S3系母鸡240只，随机分成4组，每组6个重复，每个重复10只。对照组饲喂粗蛋白质水平为16.64%的玉米-豆粕型基础饲粮，试验组分别饲喂粗蛋白质水平依次为17.64%、15.64%和14.64%的试验饲粮。试验期为40周。结果表明：1)与对照组相比，整个产蛋期内17.64%、15.64%、14.64%粗蛋白质组的产蛋率、平均蛋重和日产蛋量均显著降低(P<0.05)；15.64%和14.64%粗蛋白质组死淘率显著降低(P<0.05)，采食量显著提高(P<0.05)。2）与对照组相比，产蛋前期15.64%和14.64%粗蛋白质组受精率显著提高了9.7%和7.9%(P<0.05)，死胎率显著降低了26.1%和24.3%(P<0.05)，孵化率显著提高了15.8%和20.6%(P<0.05)。3)整个产蛋期内，15.64%和14.64%粗蛋白质组蛋壳强度显著高于对照组和17.64%粗蛋白质组(P<0.05)，17.64%、15.64%和14.64%粗蛋白质组蛋黄重显著低于对照组(P<0.05)。由此可见，15.64%和14.64%粗蛋白质组限饲能够对肉种鸡生产性能、繁殖性能及蛋品质产生显著影响，其中15.64%粗蛋白质组综合效果最佳。

Abstract：本试验旨在探索添加大豆黄酮后对肉种鸡产蛋和繁殖性能的影响。选取43周龄体况接近一致（体重、产蛋率）的肉种鸡S2系母鸡240只，随机分成4组，每组6个重复，每个重复10只：选取1组作为对照组，饲喂无大豆黄酮的基础饲粮，其余3组分别在基础饲粮基础上添加5、10、20 mg/kg大豆黄酮。再挑选20只强健的S2系公鸡采集精液，混精对试验鸡进行人工授精，试验期为15周。结果表明：与对照组相比，1)添加大豆黄酮对S2系母鸡体增重、采食量及死亡率无显著影响(P>0.05)。2）添加大豆黄酮后能显著提高产蛋率(P<0.05)，其中10 mg/kg组产蛋率提高了4.1%(P<0.05)，日产蛋量提高了3.5%(P<0.05)，为3组最佳。5、10 mg/kg组料蛋比分别降低了8.0%和11.2%(P<0.05)。3）10 mg/kg组受精率、孵化率和健雏率分别提高了13.1%、20.5%和5.8%(P<0.05)。由此可见，饲粮中添加大豆黄酮能显著影响肉种鸡产蛋和繁殖性能，其中10 mg/kg组综合效果最佳。
