FM-to-AM(frequency modulation-to-amplitude modulation)conversion caused by nonuniform spectral transmission of broadband beam is harmful to high-power laser *** by spectral dispersion(SSD)beam is a special broadband beam for its monochromatic feature at the given time and space on the near *** traditional method which uses the optical spectral transfer function as filters cannot accurately describe its AM *** paper presents the theoretical analysis of the etalon effect for SSD *** a low-order approximation,the analytic model of the temporal shape of SSD beam is obtained for the first time,which gives the detailed AM characteristics at local and integral aspects,such as the variation of ripples width and amplitude in general *** also analyze the FM-to-AM conversion on the focal plane;in the focusing process,the lens simply acts as an integrator to smooth the AM of SSD *** AM control is necessary for the near field to avoid optics damage and for the far field to ensure an optimal interaction of laser-target,our investigations could provide some important phenomena and rules for pulse shape control.

Using MCMC Probit Model to Value Coastal Beach Quality Improvement

2013年教育技术与管理科学国际会议

作者： Jing liu jingqin su Academic Department of Management and Economics Dalian University of Technology

We conceptualize and empirically test a mode that links different types of market orientation and product innovation, moderating by dynamic capabilities. survey responses from China’s manufacturing industry firms indicate that niche market orientation is more strongly positively related with product innovation than is mass market orientation. Meanwhile firms with high levels of dynamic capabilities better effects two types of market orientation and product innovation. The results have significant implications for firm strategies to facilitate product innovations and achieve competitive advantages.

作者： Zuozhi Li Erda wang jingqin su Yang Yu 不详

Dichotomous choice elicitation technique of contingent valuation method is broadly used in the research fields of environmental resource and recreational activity management. The binary choice type of questions are generally analyzed by using Logit or Probit probability distribution models in which a common analysis procedure is to apply MLE for estimating variable parameters before calculating the respondents’ willingness to pay. In this paper, a MCMC Gibbs sampling Probit model is adopted to maintain the three advantages it has in dealing with heteroscedasticity, high dimension numerical integral and sample size restriction problems. The results revealed that the MCMC model and MLE Probit model are strikingly consistent, which suggests that the former is much simple and reliable estimation method. At the same time, the empirically based existence value estimation of coastal beach quality improvement in Dalian, China is RMB?168 per person.

作者： Ping Li Sai Jin Runchang Zhao Wei Wang Fuquan Li Mingzhong Li jingqin su Xiaofeng Wei Research Center of Laser Fusion of China Academy of Engineering Physics

In indirect drive, reducing peak intensity of a single beam and controlling overlap of multi-beams are two opposite requirements for laser focal spot design. In this paper, an improved laser spot design technique for indirect drive built upon the geometric structures of laser propagation into hohlraum has been introduced. The proposed technique is able to generate appropriate continuous phase plate(CPP) producing a special shaped spot that can balance the opposite requirements. The corresponding CPP does not bring difficulties to the design and fabrication. Phase aberrations are more sensitive to the special shaped spot; however, it can be tolerable for the current beam control level.

管理学科的实践属性决定了管理理论具有较强的时空情境依赖特征。本土情境作为中国企业成长不可分割的基本载体,也是促进管理理论与特色实践交融共生的底层影响要素。鉴于当前普遍存在“西方理论难适用”与“本土理论难开发”的共性问题,背后均指向对本土情境认知的泛化、碎片化、静态化等问题。本文通过对VUCA时代本土管理情境特征的结构化梳理,刻画了本土情境演变的动态谱系和情境要素间的复杂组合,由此呈现出兼具静态与动态、时间与空间、单一要素与多元组合等多维视角下的复合情境观。进而,在促进本土情境认知结构从离散化、架构化向谱系化与组合化演进的同时,研究进一步探索了复合情境观在本土管理理论建构过程中的嵌入角色与作用。通过明确时空情境敏感性下的“新背景-新过程”双维问题筛选机制,厘清本土情境在理论研究过程中的“嵌入”与“涤除”平衡策略,推动本土管理理论研究走向兼顾“本土特色”与“整体普适”的深度情境化阶段。

Based on an explorative embedded single-case study, this paper analyzes its import-based innovation process, identifies characteristics of manifestation of organizational inertia＇s effects, and reveals organizational learning＇s effects on firms＂ organizational inertia. The case selected is the successful practice about typical technology import of internal combustion locomotive, electric locomotive, and diesel engine, owned by Dalian Locomotive and Rolling Stock Ltd Company of CRRC. Based on analysis, it can be found that firms＇organizational inertia exhibits primarily negative effects, positive effects and a combination of positive and negative effects in different stages of imitative, improved and indigenous innovation respectively. Further analysis of typical events shows that explorative learning mitigates organizational inertia＇s negative effects, while exploitative learning enhances its positive effects. From the angle of organizational inertia＇s effects, this paper deepens understanding on the mechanism of transition from technology importation to indigenous innovation, and provides inspirations for late-coming firms to break the vieious cycle where technology importation leads to more backwardness..

认为产学研合作创新是一种经济行为。运用产权经济学中的交易成本概念，指出该项活动的交易成本包括沟通成本、谈判成本、履约成本和其它成本，分别对这四种成本进行了探讨。根据交易成本的概念，提出避免现存组织模式交叉重迭的分类方法：即分为内部化模式、外部化模式、半内部化模式三种模式，认为内部化模式和外部化模式分别在不同条件下具有交易成本小的优势，而半内部化模式是一特殊模形式。提出了内外部化的条件：对内部化而言，需要一定的规模、技术能力、资源能力与经济管理能力；对外部化而言，需要技术供方的核心能力、技术需方吸纳技术的能力和较为规范及功能较强的技术市场管理机构。同时。

隐形冠军企业如何实现战略逻辑动态演化来适应复杂多变的情境以建立持续性竞争优势,成为学界与业界日渐关注的重要议题。基于注意力配置视角,通过纵向单案例研究方法解析了隐形冠军企业战略逻辑形成及演化的内在机理。研究发现:首先,隐形冠军企业各阶段战略逻辑形成路径是管理者基于当前经营目标,通过对内外部情境信息进行注意力配置,来构建出包括认知倾向度不同的关注焦点及其之间因果逻辑的注意力结构分布的过程;其次,持续保持对内外部情境信息动态变化的警觉性,驱动着管理者以在细分领域中占据较大市场份额为基本认知取向,通过对注意力结构分布进行适配性调整,促使隐形冠军企业战略逻辑发生动态演化;最后,具有不同来源的稳定性与策略性属性特征分别所扮演的“调节器”角色与“适配器”角色,共同促使隐形冠军企业战略逻辑能够平稳及时地在利基市场中实现动态演化。
