智能手表的春天真的来了吗?

手表发展至今,已经过了数轮的演变,从最初的机械表、晶体管摆轮表到光波表、电子表等,其中也不乏有创新、独特的多功能手表.然而,手表的存在方式并没有因为所谓智能手表的出现而得到大众的认可与普及,依然只是少数人的玩物. 近段时间,智能手表的话题又被炒得火热,苹果软性屏幕专利曝光,三星Galaxy Altius智能手表接踵而至.两家巨头将智能手表的话题带入人们视线的同时,Pebble智能手表的创始团队在Kickstarter上获得了1000万美元的公众集资,并在1月份开始发售手表.同时,印度厂商Androidly Systems Private也发布了智能手表Androidly,中国盛大网络旗下的果壳电子也正式宣布正在研发Bambook Smart Watch.     

苹果发布会上的尴尬——再也没有什么重新定义手表了

<正>一个做噱头、晒土豪的产品究竟能活多久?不是所有科技都适合给自己打上高奢标签,苹果也不例外。穷玩车,富玩表。苹果公司CEO蒂姆·库克在最近一次接受媒体采访过程当中表示,苹果公司的Apple Watch是史上第一款现代化的智能手表,也是第一款产生重要影响的智能手表。然而这种王婆卖瓜式的自卖自夸,似乎并没有让这块最高售价高达19999美元的手表在评论界获得一致好评。为什么苹果的产品越发"土豪"了?"Spring Forward",短短两     

Android Wear:打响与苹果穿戴设备的第一枪

“机器换人”成东莞产业升级突破口

<正>制造业是"制造之都"东莞发展的根基、特色和优势所在。但与此同时,东莞制造业主要位于产业价值链中低端,存在发展方式粗放、创新能力薄弱、产品利润较低等问题,如制造业增加值率仅为22%左右,远低于先进国家和地区35%左右的水平,加上近年来劳动成本上升导致招工难,东莞的制造业面临困境。作为"中国制造"的典型城市,在智能制造的背景下,东     

新品开发种种

功能交换法:即根据用户的不同需求,适当增减原有产品的功能,使之推陈出新,扩大市场,如日本某钟表企业,在原有的具备计时、计日、计周功能手表的基础上,进行功能增加,开发出兼具计日、计年、计世纪、计节日的多功能新品种,销路很好。材料变换法:任何产品均由若干材料组合而成,若把其中某些材料变换了,往往能使产品产生新的性能和功效。例如,某企业大胆采用新型纸张,全部或部分地取代陶瓷、铁铝铜等制造各种不生锈、可装固体、液体的容器,深受用户欢迎。"一次"开发法:现代消费讲究方便、实用,在日常生活用品的消费上尤为如此。厂家如能开发一些价格低廉,用后即扔的"一次性"使用产品,上市后一定十分畅销,国外在这方面已有成功的先例。如开发出薄蜡制

Markedness and its Interpretation in Language Use

Language markedness is a common phenomenon in languages, and is reflected from hearing, vision and sense, i.e. the variation in the three aspects such as phonology, morphology and semantics. This paper focuses on the interpretation of markedness in language use following the three perspectives, i.e. pragmatic interpretation, psychological interpretation and cognitive interpretation, with an aim to define the function of markedness.     

Features of Women's language

Language is a means of verbal communication. People use language to communicate with each other. In the society, no two speakers are exactly alike in the way of speaking. Some differences are due to age, gender, statue and personality. Above all, gender is one of the obvious reasons. The writer of this paper tries to describe the features of women＇s language from these perspectives： pronunciation, intonation, diction, subjects, grammar and discourse. From the discussion of the features of women＇s language, more attention should be paid to language use in social context. What＇s more, the linguistic phenomena in a speaking community can be understood more thoroughly.     

低渗透非均质砂岩油藏启动压力梯度研究

理论推导与室内实验相结合,建立了低渗透非均质砂岩油藏启动压力梯度确定方法。首先借助油藏流场与电场相似的原理,推导了非均质砂岩油藏启动压力梯度计算公式。其次基于稳定流实验方法,建立了非均质砂岩油藏启动压力梯度测试方法。结果表明:低渗透非均质砂岩油藏的启动压力梯度确定遵循两个等效原则。平面非均质油藏的启动压力梯度等于各级渗透率段的启动压力梯度关于长度的加权平均;纵向非均质油藏的启动压力梯度等于各渗透率层的启动压力梯度关于渗透率与渗流面积乘积的加权平均。研究成果可用于有效指导低渗透非均质砂岩油藏的合理井距确定,促进该类油藏的高效开发。     

On Tragic Consciousness In The Works By Ernest Hemingway

As an American modern novelist who were famous in the literary world, Hemingway was not a person who always followed the trend but a sharp observer. At the same time, he was a tragedy maestro, he paid great attention on existence, fate and end-result. The dramatis personae's tragedy of his works was an extreme limit by all means tragedy on the meaning of fearless challenge that failed. The beauty of tragedy was not produced on the destruction of life, but now this kind of value was in the impact activity. They performed for the reader about the tragedy on challenging for the limit and the death.     

Achieving Unusual States of Matter Under High Pressure

正The periodicity of the elements and the non-reactivity of the inner-shell electrons are two related principles of chemistry,rooted in the atomic shell structure.Within compounds,Group I elements,for example,invariably assume the+1 oxidation state,and their chemical properties differ completely from those of the p-block elements.These general rules govern our understanding of chemical structures and reactions.Using first principles calcula-     

Exchange-Correlation and Electronic Excitation Energies from Pairing Matrix Fluctuations

We have developed an adiabatic connection to formulate the ground-state exchange-correlation energy in terms of pairing matrix linear fluctuations.This formulation of the exchange-correlation energy opens a new channel for density functional approximations based on the many-body perturbation theory.We illustrate the potential of such approaches with an approximation based on the particle-particle Random Phase Approximation(pp-RPA).This re-     

Density Functional Theory for the Response of Periodic Systems to Electric Fields Based on the Vector Potential Approach

正The electronic and nuclear(structural/vibrational)response of 1D-3D nanoscale systems to electric fields gives rise to a host of optical,mechanical,spectral,etc.properties that are of high theoretical and applied interest.Due to the computational difficulty of treating such large systems it is convenient to model them as infinite and periodic(at least,in first approximation).The fundamental theoretical/computational problem in doing so is that     

On the Thermodynamic Limit for Responses to Static Electromagnetic Fields

For molecular systems,the quantum-mechanical treatment of their responses to static electromagnetic fields usually employs a scalar-potential treatment of the electric field and a vector-potential treatment of the magnetic field.Although the potential for each field separately is associated with the choice of an(unphysical)origin,the precise choice of the origin for the electrostatic field has little consequences for the results.This is different for the

Franck-Condon factors bridge the gap between theoretical modeling and experimental observations for molecular electronic spectroscopy and electron transfer.Under the displaced harmonic oscillator approximation,multidimensional Franck-Condon factors are decomposed into a product of many one-dimensional(1D)Franck-Condon(FC)factors,and each 1D-FC factor is associated with one Huang-Rhys factor that determines the leading contribution of
