CHINA AND THE U.S. BEYOND THE KOREAN PENINSULA

China-U.S. cooperation over the most difficult security problem in Northeast Asia—the North Korean nuclear issue—in essence projects its bigger power game amid the tectonic shifts of Asian geopolitics. The nuclear issue affords a test case to gauge the future posture of China and the United States in East Asia and their partnership in that conflict-prone region. Approaches to resolving this issue must take into account the geopolitical realignment of Asia, Washington's reorientation of relations with its Asian allies, and China's rise as an influential regional player and the subsequent regional response. However, the long-standing mistrust between China and the United States is contributing to a lack of substantial progress in Korean nonproliferation efforts. The declared nuclear test by Pyongyang further put the denuclearization cooperation between China and the Unites States on the line. China-U.S. cooperation in denuclearizing Pyongyang may either produce lasting stability for the region or create ‘‘collateral damage,’’ with the North Korean issue paling in comparison.     

钢质油罐底板腐蚀概率估计

针对钢质油罐底板腐蚀,首先分析了油罐底板腐蚀工程检测数据的特点和腐蚀试验数据统计分析理论;然后针对工程检测信息不完全的特性,以最大腐蚀深度的预测估计为目标,建立了以轻微腐蚀面积估计来实现腐蚀概率修正估计的模型;最后利用广州等地27个罐约900条检测数据估计了油罐底板的最大腐蚀深度。其最大相对误差小于45%,约80%的相对误差优于30%。     

Market entry strategy in the presence of market spillovers and efficiency differentiation

Firms form various alliances or use brand extensions to enter new markets in order to improve their operational efficiency and create a positive spillover. However, they do not always know the implications of these strategies for market entry and multimarket competition because the sale of products in one market can have negative spillover effects on product sales in other markets. We present an analytical framework to examine whether and how (i.e., by choosing alliance entry or independent entry) competing firms should enter a market in a situation where market spillovers occur when a firm enters a spillover-producing market to sell products that may increase or decrease the consumers' willingness to pay for products in the primary market. Our analysis shows that the operational efficiency (or quality differentiation ability) of firms in a spillover-producing market varies, and hence, the impact of market spillovers differs for firms. We identify the key factors, such as bargaining power, brand value difference in the primary market, and the extent of efficiencies and spillovers, that determine the firms benefitting from the different entry strategies. Specifically, we show that firms would be more willing to choose an alliance strategy to enter a spillover-producing market if the negative spillover is small and alliance efficiency is high. In contrast, if an alliance entry is not favored, the firms' relative operational efficiency is crucial for them to decide whether to enter the market independently under moderate spillover conditions. Finally, we show the implications of market entry strategies for managers.     

空气甲醛显色球的制备

为实现快速准确测定空气中的甲醛,对4种氨基酸作为乙酰丙酮显色法的胺源进行对比分析,发现甘氨酸的显色效果较明显;对显色温度和显色时间进行优化,发现显色温度在50℃,反应15 min,显色效果明显。把显色剂固定到透明聚丙烯酸树脂球上,制备出可在家庭中方便使用的显色球,通过肉眼观察即可判断空气中甲醛的质量浓度,检测限达0.008 mg/m3。     

面向需求变化的军队自动化立体仓库货位优化

为提高军队自动化立体仓库的出库能力,提出应根据需求变化对在库物资货位进行动态调整,从而最大限度地保障军队物资需求。综合考虑堆垛机总行程、货物离散度和出库频率等评价指标,采用遗传算法对该多目标优化问题进行求解,并运用Matalab仿真。结果表明,该方法能较好地提高军队自动化立体仓库在需求动态变化时的出库能力。同时,该研究对一般仓库的货位优化也有一定的借鉴意义。     

作战飞机可靠性与维修性仿真模型

通过故障树分析建立了作战飞机仿真逻辑关系。在修正线性同余法的基础上获得了随机数模型。在各设备故障发生状态和修复状态识别的基础上,建立了可靠性维修性仿真模型,确定了作战飞机在仿真过程中的工作状态,并根据故障模式影响分析预计了设备故障对作战飞机的影响。最后以F/A-18为例进行可靠性维修性仿真,获得了实时的故障信息和修复信息,验证了仿真模型的可行性。
