New pattern recognition system in the e-nose for Chinese spirit identification

This paper presents a new pattern recognition system for Chinese spirit identification by using the polymer quartz piezoelectric crystal sensor based e-nose. The sensors are designed based on quartz crystal microbalance（QCM） principle,and they could capture different vibration frequency signal values for Chinese spirit identification. For each sensor in an8-channel sensor array, seven characteristic values of the original vibration frequency signal values, i.e., average value（A）,root-mean-square value（RMS）, shape factor value（S_f）, crest factor value（C_f）, impulse factor value（I_f）, clearance factor value（CL_f）, kurtosis factor value（K_v） are first extracted. Then the dimension of the characteristic values is reduced by the principle components analysis（PCA） method. Finally the back propagation（BP） neutral network algorithm is used to recognize Chinese spirits. The experimental results show that the recognition rate of six kinds of Chinese spirits is 93.33% and our proposed new pattern recognition system can identify Chinese spirits effectively.

Application of the new pattern recognition system in the new e-nose to detecting Chinese spirits

We present a new pattern recognition system based on moving average and linear discriminant analysis （LDA）, which can be used to process the original signal of the new polymer quartz piezoelectric crystal air-sensitive sensor system we designed, called the new e-nose. Using the new e-nose, we obtain the template datum of Chinese spirits via a new pattern recognition system. To verify the effectiveness of the new pattern recognition system, we select three kinds of Chinese spirits to test, our results confirm that the new pattern recognition system can perfectly identify and distinguish between the Chinese spirits.

NEW PATTERNS OF URBAN DEVELOPMENT IN CHINA

According to the basic features of socio economic development in China, the paper retrospects the developmental process of Chinese cities in the 20th century. Based on lots of data and related research achievements, five new patterns of Chinese urban development are pointed out, that is 1) regional disparity of urban development in China is still obvious and large; 2) cities in developed region develop in the form of agglomeration and coordination; 3) spatial layout shape of Chinese cities appears relatively tight, and there exists great outside expansion inclination; 4) the construction of exploitation zone becomes the new important factor of urban development in the 1990s; 5) number increase of cities at county level become the main tide of urban development, but cause the discrete understanding for the concept of urban substantial region, which construct a challenge to urban management. In the end the article puts forward a series thoughts on the future trends and countermeasures of urban development in China.

Intellectual Property Protection and New Development Pattern Construction of Xinjiang Jujube

"Three new developments"is the guiding ideology of Chinese-style high-quality development in the new era.Jujube(Zizyphus jujube Mill.)is a plant of Zizyphus of Rhamnaceae,which originated in China and has been listed as one of the"five fruits"since ancient times.Xinjiang is the most important jujube producing area in China,and its yield has accounted for 50%of the national jujube yield.In the five prefectures and cities of southern Xinjiang,as well as the regimental farms of southern and eastern Xinjiang of Xinjiang Production and Construction Corps,the jujube industry is an advantageous characteristic industry in agriculture.This paper studied Xinjiang jujube industry and its agricultural intellectual property resources,analyzed six major issues to be further implemented,such as the"three new developments"thinking and the strategy of building an intellectual property power,and puts forward eight strategies such as coordinating the two markets and two resources to accelerate the construction of a new development pattern and dual circulation of jujube.

The Africanness of African Literatures and New Patterns in Human Civilization

The explosion of African literatures in 2021 is not a coincidence,but is dictated by the continent's decolonial,diasporic and hybrid cultural manifestations,its more than a hundred years of struggle for cross-regional integration,its spirit of vigorous and persistent action,and the unique attraction of an Africanness that upholds its selfhood,bridges the gaps,and remembers its history but looks to the future.The diasporic characteristic of attending to,absorbing and squarely facing the tension of heterogeneous cultures means that indigenous African literatures contain a distinctive world consciousness and rational philosophy.They have given rise to diverse civilizations marked by dialogue,inclusiveness and the contemporary spirit of African nations,enabling African literatures to participate effectively in the dialogue of world literature and in new patterns of civilization,displaying as they do a strong vitality,creativity and influence in the positive-sum game with Western culture.This will provide positive encouragement to the mutual learning,integration,harmony,symbiosis andcoexistenceofcivilizations.

China's Scientific and Technological Innovation Strategy under the New Pattern of Development

Innovation is the driver and accelerator for high-quality economic development and the transformation and upgrading of enterprises.At present,the world is undergoing significant changes unseen over the last century.Faced with the new world economic pattern and the new international relations in the postpandemic era,China should systematically clarify the prominent problems with the current scientific and technological(S&T)system,and establish new technological innovation strategies in the new era and new economic landscape,which are of great significance.Especially in the context of the new pattern of development,it is greatly highlighted how to systematically lower over-dependence on core technologies and resolve bottleneck problems with core technology arising from excessive attention to the international economic flows.Based on the medium-and long-term strategic background of the current new pattern of development,this paper explores the prominent problems of the S&T innovation system under the background of the new pattern of development from the perspectives of innovation policy system,regional innovation system,and enterprise innovation mode.Meanwhile,the paper believes that the innovation guidance system under the new pattern of development needs to be realized based on the guidance of the new innovation strategy of"opening thinking based on bottom lines and comprehensive indigenous innovation,"and also the three leading paths of holistic innovation guided by the new pattern of the whole national institutional system,the future industry,and the world-class enterprises.Only in this way can China become a power in terms of S&T innovation in the world.

China’s Industrial Upgrading and Value Chain Restructuring Under the New Development Pattern

Global industrial chains(GICs)have become a hallmark of the world economy underpinning the global production cycle.Since the reform and opening up was introduced in 1978,China has taken an active role in global value chains(GVCs)and become the world’s factory floor.Under the external shocks to GICs,such as US trade frictions with China and the COVID-19 pandemic,China’s traditional comparative advantages in manufacturing which include its labor force and costs are waning.This has manifested in a wave of industrial relocations from China to other countries as well as China’s weakening international competitiveness.We took stock of the concepts and journey of GVCs and elaborated the intrinsic relationship between GVCs and the new development pattern of“dual circulations”.We also analyzed the trends of GVCs,the current status and problems of China’s industrial chains,and China’s market heft,complete industrial chains and the digital economy as new strengths for industrial chain upgrade.In our conclusion,this paper put forth some policy recommendations for China’s industrial chain upgrade in the context of dual circulations.

The Key Driver of China’s New Economic Development Pattern:A Major Power’s Flying Geese Paradigm

This paper examines China’s flying geese paradigm that serves as a key driver of a new pattern of the country’s economic development.Our results suggest that such a major power’s flying geese paradigm has taken shape in the aftermath of the global financial crisis in 2008.However,this paradigm has provincial heterogeneity in that industrial relocation varies across provinces.For instance,China’s central and western regions have shown differences while serving as destinations for labor-intensive industries and processing trade.This flying geese paradigm evolves in a slow and nonlinear manner,and may be subject to stagnation and even reversal.

A NEW METHOD FOR CONSTRUCTING DIGITAL-STRAIN-FIELD-IMAGES FROM MOIRE PATTERNS

A new method for constructing digital-strain-field-image from a moire pattern with the help of digital image processing technique is proposed in this paper. The digital-strain-field-image expresses the strain values directly by its grey levels. The digital-strain-field-image can be obtained by making a differentiation for the digital moire pattern and doing a simple division operation. This image not only gives the visual strain field distribution, but also gives the strain values of every point. This method is simple and applicable and has satisfactory accuracy.

新发展格局下提升产业链供应链韧性与安全的难点与着力点

从“两头在外”“大进大出”模式转向构建以国内大循环为主体、国内国际双循环相互促进的新发展格局,既是对产业链供应链安全风险的积极应对,也对产业链供应链水平提出更高要求。虽然我国已形成完整的产业链条和完善的产业配套,但与世界领先水平相比仍存在差距,包括:产业规模大,但高技术产业比重较低;产业链相对完整,但关键环节薄弱;创新能力增强,但产业链引领力较弱;产业集群优势明显,但产业根植性不强。提升我国产业链供应链韧性与安全面临多重难点,包括产业链外迁压力加大了保持产业链完整性的难度,畅通国内大循环的紧迫性加大了补链强链的难度,美西方国家的脱钩断链加大了产业技术创新难度,国内市场分割加大了形成接断点补短板合力的难度,长期处于赶超阶段加大了在“无人区”锻长板的难度。提升产业链供应链韧性与安全可以从优化要素组合、保持传统制造优势,发挥综合优势、补齐产业链关键短板,发挥超大规模优势、增强产业链引领能力,加强国际合作、优化产业链全球布局等方面着力。

服务业开放、数字化赋能与国际循环质量提升

服务业高水平对外开放及数字赋能,是我国进一步提升国际循环质量和水平的重要内容,也是构建新发展格局的有力抓手。自改革开放以来,我国服务业开放已历经45年,但服务贸易发展不均衡不充分的特征依旧明显。从生产成本,贸易成本,贸易方式、贸易对象和贸易主体等层面,对我国服务贸易开放发展进行数字化赋能,现阶段仍存在政策性壁垒较高等问题。从全球价值链分工的视角看,继续逐步降低服务要素流动的政策性成本,能够从全球价值链分工地位、全球价值链参与的安全性与稳定性以及国际经贸规则制定中的话语权等方面,提升我国的国际循环质量。此外,数字技术的发展同样能够以独立或者与服务业开放互动的形式促进我国国际循环质量的提升。

消费中心城市项目布局研究:分类、属性及途径

消费中心城市项目是消费中心聚集消费资源的重要载体,是服务消费者、引领消费潮流、发挥消费影响力的主要方式,项目成功与否是消费中心成败关键。对消费中心城市项目进行不同维度的分类,包括文化消费项目和物质消费项目、服务消费项目和商品消费项目、最终消费项目和中间消费项目、直接消费项目和间接消费项目、必要消费项目和非必要消费项目等,每种分类维度都有一定的分析意义。消费中心城市项目具有多种消费经济发展特性,包括消费的范围经济性、中心的规模经济性、文化消费的无限性和物质消费的有限性、消费的空间协调性、消费的系统制约性。在消费中心城市项目布局中,文化消费是关键,需要重点布局文化消费项目;物质消费带动潜力大,需要全面规划物质消费项目;空间资源紧张、空间成本高,需要通过中心紧密原则布局相关项目;消费系统配套性强,需要对消费中心城市项目进行超前和空间延展性布局;消费中心城市项目经济平衡作用显著,需要在欠发达地区做更多布局。
