摘要：本文采用了体验经济的理论框架,对影响电影票房的因素进行分类,并发展了新的研究变量,因变量有总票房、第一周票房和放映时间长度,自变量有四类:品牌相关变量、客观特征、信息源头、发行相关因素。续集、演员、成本、类型(剧情),MPAA分级(PG和R),发行档期(暑期和复活节),第一周上映影片的荧幕数与总票房都显著相关。

摘要：针对雾中能见度探测问题,利用准直镜代替了传统的发射望远镜,透镜组作为激光接收系统,设计了一套小型米散射激光雷达系统,实现了系统的小型化和紧凑化;计算了系统的几何重叠因子,从而得到回波信号的有效提取距离。通过Collis斜率法对室内雾探测结果进行反演获得雾的消光系数和雾中能见度及其他变化特征。实验结果表明:小型米散射系统对雾中能见度的探测是可行的。

摘要：Flow characteristics inside a cyclone filter were investigated by the use of computational fluid dynamics(CFD). For computations, SST model was adopted. Parametric study was carried out considering the filtering performance. Revolution speeds were changed from 100 to 550 with 50 increments. A skirt is the driving source for cyclone operation. The influence of several design factors, such as the skirt length, the skirt gap and the return length to filtering performance was investigated under the particle diameter 100μm of debris material(Al, s.g.=2.7). The filtering performance was also investigated with the skirt length 28 mm changing the debris diameters from 1μm to 50μm. The flow rate of the working fluid was maintained at 0.55kg/s. It has been verified that the most influential factors to the filtering efficiencies was the skirt gap between the cyclone generator and the cyclone vessel.

摘要：Three-dimensional （3D） printing is a novel process used to manufacture bone tissue engineered scaffolds. This process allows for easy control of the architecture at the micro structure. However, the scaffold properties are typically limited in terms of cellular activity at the scaffold surface due to the printed materials properties. In this study, we developed a polycaprolactone （PCL） blended with polyethylene glycol （PEG） 3D printed scaffold using a rapid prototyping system. The manufactured scaffolds were then washed out to form small pores on the surface in order to improve the scaffolds hydrophilicity. We analyzed the resultant material by using Scanning Electron Microscopy （SEM）, water absorption, water contact angle, in vitro WST-1, and the Bradford assay. Additionally, cells incubated on the fabricated scaffolds were visualized by Confocal Laser Scanning Microscopy （CLSM）. The developed scaffolds exhibited small pores on the strand surface which served to increase hydrophilicity as well as improve cellular proliferation and increase total protein content. Our findings suggest that the presence of small pores on the scaffolds can be used as an effective tool for improving implant cellular interaction. This research indicates that these modified scaffolds can be considered useful for bone tissue engineering applications to improve human health.

摘要：铁素体含量对不锈钢焊缝的耐蚀、韧性、强度等性能有重要影响,准确测量或预测十分重要.铁素体含量的测试与预测方法有很多种,最常使用的是图谱法和磁测法,介绍这两种方法的最新进展.在不同实验室制备及测量试样、试样表面是否进行处理等都会影响测试与预测结果的精度.铁素体数（Ferrite number,FN）小于5时,不同实验室之间图谱法预测结果的波动是平均值的±60％,铁素体数在15～35时,图谱法预测结果的波动是平均值的±30％.磁测法测量的波动是平均值的±20％,小于图谱预测法,是目前较精确的测试方法.新的预测方法考虑了元素之间相互作用和冷却速度等因素对铁素体含量的影响,提高了预测的精度.针对铁素体数测试结果不可避免的波动问题,提出目标范围这一概念来解决焊材设计者与使用者对测试结果产生的分歧.

摘要：We propose a single-poly MTP （multi-time programmable） cell consisting of one capacitor and two transistors based on MagnaChip＇s BCD process. The area of a unit cell is 37.743 75μm^2. The proposed single-poly MTP cell is erased and programmed by the FN tunnelling scheme. We design a 256 bit MTP memory for PMICs （power management ICs） using the proposed single-poly MTP cells. For small-area designs, we propose a selection circuit between V10V and VSV, and a WL （word-line） driver by simplifying its logic circuit. We reduce the total layout area by using pumped internal node voltages from a seven-stage cross-coupled charge pump for V10V （=10 V） and V5V （=5 V） without any additional charge pumps. The layout size of the designed 256 bit MTP memory is 618.250 μm × 437.425μm.

摘要：水稻穗部是重要的农艺性状之一,穂顶部颖花退化会导致水稻产量大幅下降。本研究对水稻穗退化T-DNA突变体进行分子鉴定和表型分析,旨在进一步探明水稻穗发育的调控机制。我们从水稻突变体库POSTECH RISD(Rice T-DNA Insertion Sequence Database)中筛选到了3个T-DNA插入突变体,paa1、paa2和paa3。这些突变体中T-DNA分别插入到水稻穂顶部颖花退化候选基因LOCOs04g56160的第1个内含子、第8个外显子和3′端非翻译区。分别在T-DNA插入位点两侧水稻基因组和T-DNA片段上共设计3条引物,利用PCR方法鉴定出paa1、paa2和paa3突变纯合体与杂合体。3个突变杂合体自交后代(T3)植株表型与基因型共分离分析结果显示,paa1及paa2植株的穗顶部颖花退化表型与基因型相吻合,而paa3植株的颖花发育正常。paa2与PAA-Hwa(LOCOs04g56160基因点突变体,表型为穗顶部颖花退化)杂交,F1代植株表现为穂顶部颖花退化。农艺性状调查结果表明,paa1及paa2与对照品种相比在株高、穗长、单株有效分蘖数等所有农艺性状上存在显著差异,然而paa3仅在部分农艺性状上表现差异。以上结果表明paa1和paa2为穗顶部颖花退化T-DNA插入突变体,LOCOs04g56160为水稻穗顶部颖花退化调控基因,该结果为水稻穗发育研究奠定了理论基础。
