七姊妹山国家级自然保护区悬钩子属植物资源及开发利用研究

悬钩子属是蔷薇科中的一个大属,全世界有悬钩子属植物750余种。在野外调查和文献资料查阅的基础上,对七姊妹山国家级自然保护区悬钩子属植物的野生种的分布、生长习性等现状进行了研究。结果表明：该保护区有悬钩子属植物35种和7变种,且资源蕴藏量大。按其用途可将其分为食用植物类、药用植物类、工业用植物类和观赏植物类等,如能有计划地加以开发利用,对当地经济发展将会起到积极的促进作用。     

Assessment of Containment Structures Against Missile Impact Threats

In order to ensure the highest safety requirements, nuclear power plant structures (the containment structures, the fuel storages and transportation systems) should be assessed against all possible internal and external impact threats. The internal impact threats include kinetic missiles generated by the failure of high pressure vessels and pipes, the failure of high speed rotating machineries and accidental drops. The external impact threats may come from airborne missiles, aircraft impact, explosion blast and fragments. The impact effects of these threats on concrete and steel structures in a nuclear power plant are discussed. Methods and procedures for the impact assessment of nuclear power plants are introduced. Recent studies on penetration and perforation mechanics as well as progresses on dynamic properties of concrete-like materials are presented to increase the understanding of the impact effects on concrete containment structures.

亚硫酸氢钠对转PEPC基因水稻叶片光合作用的促进作用

用1～2mmol／L的NaHSO3喷施于野生型水稻Kitaake(WT)、以其为基因受体的转PEPC基因水稻(PC)和转PEPC PPDK双基因水稻(PC PK)叶面．叶片的光合速率分别提高了23．0％、28．8％和32．4％，并能持续3d左右．在此条件下，光下叶片中的ATP含量提高．将已知可促进循环光合磷酸化的辅助因子硫酸甲酯吩嗪(PMS)和NaHSO3分别和共同喷洒叶片，次日所有叶片的光合速率均比对照(喷水)提高，共同处理未出现叠加效应，表明NaHSO3的主要作用和PMS促进光合速率的原因类似，都是增加了ATP的供应．与野生型水稻Kitaake(WT)相比．经NaHSO3处理后，转PEPC基因水稻(PC)净光合速率增加的幅度大，转PEPC PPDK双基因水稻(PC PK)净光合速率增加的幅度更大，因此认为水稻叶片中增加ATP的供应可明显增强水稻的光合速率，特别是转PEPC或PEPC PPDK基因水稻．

Developing an interactive augmented reality system as a complement to plant education and comparing its effectiveness with video learning

The learning of plants has garnered considerable attention in recent years, but students often lack the motivation to learn about the process of plant growth. Also, students are not able to apply what they have learned in class in the form of observation, since plant growth takes a long time. In this study, we use augmented reality (AR) technology to develop the ARFlora system, which can assist students in observing the changes in plant growth while in the classroom. More specifically, students are able to use AR markers to manipulate various virtual objects (e.g. sunlight) and observe the changes they have on plant growth. Meanwhile, a quasi-experimental evaluation is in place to substantiate the effectiveness of ARFlora in the learning of plants and to compare it with digital video learning. In the quasi-experimental design, 55 elementary-school students participated in the study. The participants are divided into two groups, an “experimental group” and a “control group.” The experimental group was taught using the ARFlora system, while the control group was taught by employing the digital video. Results show that (1) ARFlora and digital video have the same effectiveness on student's learning outcomes; (2) ARFlora is more effective in helping students retain learned knowledge; and (3) ARFlora is comparatively more useful in motivating students to learn about plants.
