Color words play an important role in the different cultural languages. As the background of Chinese and English culture varies each other, the usage of color word also differs greatly. In order to understand inner meaning better, people must adopt some different transhtion techniques in translating materials (such as literal translation, flee transhtion, change and addition of some color words, etc. ) so as to translate English color words in an accurate way. As a result, it can help people make cross-cultural more effectively and promote the cultural exchange and hybrid between English and Chinese nationalities.  相似文献

针对突发信号解调中多普勒频偏大的问题,提出了一种改进的连续相位移频键控信号(CPFSK)频率估计方法。首先接收信号平方运算使信号的调制指数加倍,再通过一次离散傅里叶变换(DFT),用搜索信号平方谱谱峰的方法实现突发信号频率估计。仿真实验表明,在低信噪比条件下,该算法的频率估计精度比经典的相位差频率估计算法提高了20%;该算法与广泛用于高动态突发信号的频率插值估计算法相比,同道干扰信道下信干比改善可达4 dB,DFT长度缩短约1/3。  相似文献

This study was designed to examine antecedent factors that yielded a model of purchase intention of dietary supplements in sexually oriented advertising. Results suggested that sexual cognition, gender difference, individual attitude toward advertisements, and product involvement were yielded as key predictors toward people's purchase intention of dietary supplements. However, sexually oriented advertising did not considerably increase their purchase intention. A regression analysis also loaded sexual cognition and product involvement as two key determinants in the model of purchase intention of dietary supplements. Moreover, people with a more positive level of sexual cognition significantly resulted in their higher degree of purchase intention of dietary supplements.  相似文献

Rural residential land transition (RRLT) dominates rural land use transition. Therefore, analysing the laws of transition and differentiation of land use is not only the basis for the differential management of rural residential areas but key to the sustainable use of rural land. This study constructs a conceptual model of RRLT using multi-period remote sensing monitoring data based on a comprehensive index method, ArcGIS, and FRAGSTATS landscape pattern analysis, among others. It also analyses the characteristics of the transition extent, transition trend, transition morphology, and transition intensity of rural residential land in the Beijing-Tianjin-Hebei (BTH) region from 1980 to 2018. The results show that, from a vertical comparison of long time series, the transition extent is characterised by a process of ‘slow growth—expanding start—fast expansion—slowing down’; the transition trend is characterised by an increase in the amount of cultivated land occupied by rural residential land, followed by a large number of rural residential land is reclaimed as cultivated land; the transition morphology is characterised by an increase in mean patch size and degree of irregularity, as well as aggregation; and the transition intensity is characterised by fluctuations in the process of ‘small-scale reduction—small-scale growth—substantial growth—small-scale growth and reduction’. A horizontal comparison of counties in the BTH region reveals a long-lasting and active growth trend in transition extent and transition intensity in the Beijing-Tianjin region, and a gradually slowing trend in the areas around the region. The transition morphology features of the northwest Hebei region are more prominent, and show that the scale of rural settlements is small, the plaques fragmented and irregular, and the layout more scattered. The BTH region should formulate a differentiated transition direction for rural residential areas based on the different functional areas, and play into the agglomeration, scale, and synergy effects of urban agglomerations. It should also coordinate and improve the human–land relationship in rural areas, and construct an orderly and densely distributed pattern of urban and rural spatial development with a reasonable layout and complementary functions.  相似文献

High‐speed rail (HSR) has led to a transportation revolution in China. This paper uses the county‐level panel data of China’s Yangtze River Delta to investigate the effect of HSR connection on local economy. To address the issue of endogenous HSR route placement, we use a straight‐line strategy to construct potential HSR connection variables as instrumental variables of the actual HSR connection. Both the difference‐in‐differences and instrumental variable methods show that HSR connection impedes local economy, especially in peripheral regions. The impediment effect is channeled through population reallocation from peripheral to core areas and the restructuring of industries.  相似文献

This study examines financial analyst coverage for U.S. firms following an increase in foreign product market competition. To capture exogenous shocks to domestic firms' competitive environments, we exploit a quasi‐natural experiment from large import tariff reductions over the 1984 to 2005 period in the manufacturing sector. Using data for the years before and after large tariff reductions, our difference‐in‐differences analysis shows evidence of a significant decrease in analyst coverage for incumbent U.S. firms when they face greater entry threat from foreign competitors. We also find that analysts with less firm‐specific experience and less accurate prior‐period forecasts are more likely to stop following the domestic firm when foreign competition intensifies. Overall, the findings suggest that foreign product market competition from global trade liberalization is an important determinant of financial analysts' coverage decisions.  相似文献

针对多源信号关联难度大、关联准确率低的问题,利用同一目标平台上搭载的多个辐射源信号具有一致的动态变化趋势这一特点,提出一种利用相位差特征的多源信号关联方法。已知阵列形式和侦测点位置,通过对侦收到的多个辐射源信号进行处理,获取相位差信息并累积形成相位差变化趋势;对比提取疑似相似段,根据相似性判决策略进行有效关联。该方法能有效避免不同传感器对位置测量的误差影响,相比传统基于位置信息关联的方法,能有效提升关联准确率。仿真和实测数据分析证明了该方法的有效性,在阵列形式和侦测点位置已知的条件下该方法具有重要工程意义。  相似文献

基于2001~2017年中国工业分企业所有制-分地区-分行业的面板数据,利用相对劳动生产率和变异系数指标对全国和分区域的国有企业、私营企业、外商和港澳台企业的劳动生产率增长和收敛性进行描述性分析,并运用双向固定效应模型对其进行计量检验。结果显示:从全国范围来看,三类所有制结构的劳动生产率均呈现显著的绝对收敛和条件收敛,但是收敛速度呈现差异。其中,私营企业收敛速度最快,外商和港澳台企业次之,国有企业收敛速度最慢。分区域来看,东北和西部收敛速度相对较快,中部次之,而沿海三类所有制结构的劳动生产率收敛速度均较慢。因此,政府应进一步从深化国有企业改革、鼓励非公有制经济发展和完善市场竞争等方面努力,有助于缩小区域发展差距和促进所有制结构的收敛,从而带动整体经济的收敛。  相似文献

在国际营销活动中,文化环境是极其重要而又极易被忽略的一个因素,文化差异往往成为企业跨国经营的无形壁垒。那么在国际营销过程中,文化差异问题该如何解决?本人个人认为,主动调整营销战略,积极融入当地市场是最好的解决方法。本文从文化差异的角度着手,以迪斯尼乐园为案例,通过对其在跨文化经营中的成功和失败的案例进行分析,阐述了跨文化运营中存在的问题,并提出了一些相关建议。  相似文献
