The basic objective of comprehensively deepening reform of the state sector of economy in the new chapter is to fully integrate this sector with a sophisticated market economic system with the market playing the decisive role in resource allocation. In order to achieve this objective, China is confronted with the four major priorities of adjusting the functions and layout of the state sector of economy according to national mandates, expediting the mixed ownership reform, creating a classified and multi- tiered new system for the administration of the sector, and developing a modern corporate system for SOEs to ensure an efficient micro-level governance mechanism for the sector. （1） The functions of the different types of SOEs should be accurately defined and SOEs should be divided into the three types of public policy SOEs, functional SOEs, and commercial SOEs. This classification forms the premises for reforming the state sector of economy. Based on the functions of the three types of SOEs, the directions and emphases for strategic adjustment should differ as well. （2） The mixed ownership reform should adhere to the methodological principles of combining top-down and bottom-up approaches, implementing pilot programs, and promoting coordinated progress. Practical implementation should ensure fair and standard reform procedures, reform programs consistent with laws and regulations, open and fair equity transfers, as well as fair and transparent internal distributions. The mixed ownership reform of SOEs should introduce the employee stock ownership system and adhere to the principles of compatible incentives, shared growth, and long-term development. Monopolistic sectors should be transformed into competitive market structures to create conditions for the implementation of mixed ownership for SOEs. （3） The new system for the administration of the state sector of economy should comprise three hierarchies： the Commission for the Administration of State Economy at the top level, state capital operation companies or state capital investment companies at the intermediate level and general for-profit enterprises at the bottom level, which administer public policy, functional SOEs, and commercial SOEs respectively. （4） Under the new system for the administration of the state sector of economy characterized by the three hierarchies and categories, the key for perfecting the modern corporate system of SOEs is to establish a differentiated, classified governance mechanism, i.e., different corporate governance mechanisms should be created for SOEs of different functions and roles.展开更多

Comprehensive identification of these potential faults and fractures that cannot be distinguished directly from seismic profile of the complex structures is still an unanswered problem. Based on the compressional structural geometry and kinematics theories as well as the structural interpretation from seismic data, a set of techniques is established for the identification of potential faults and fractures in compressional structures. Firstly, three-dimensional(3D) patterns and characteristics of the faults directly interpreted from seismic profile were illustrated by 3D structural model. Then, the unfolding index maps, the principal structural curvature maps, and tectonic stress field maps were obtained from structural restoration. Moreover, potential faults and fractures in compressional structures were quantitatively identified relying on comprehensive analysis of these three maps. Successful identification of the potential faults and fractures in Mishrif limestone formation and in Asmari dolomite formation of Buzurgan anticline in Iraq demonstrates the applicability and reliability of these techniques.展开更多

文摘Currently,the International Maritime Organization(IMO)has approved and implemented the assessment requirement for Minimum Propulsion Power(MPP)of ships in adverse sea conditions.The assessment method and relevant influence factors will have a vital impact on ship's design and operation.On the other hand,MPP is essentially a criterion for manoeuvring safety at actual seas.However,the practical assessment methods adopted in IMO guidelines do not directly and accurately account for ship's coursekeeping ability in severe seas.A time-domain comprehensive method with supplementary course-keeping ability criteria has been proposed in the authors'preliminary research.Based on an updated mathematical model and criteria,this paper presents more detailed elaborations,results and discussions on the time-domain method,including the comparative analyses with a power line method and two steady-state equilibrium methods based on IMO guidelines and draft.Discussions on the influences of key factors,involving criterion conditions and calculation parameters,are also presented.The results indicate that different methods exhibit varying advantages and complexity in MPP assessment,thus constituting a multi-level assessment framework for MPP.In particular,the time-domain comprehensive assessment has a higher accuracy with more realistic description of manoeuvre behaviors,capable of offering a solution for the ships that cannot meet other assessments,or for the assessment requiring additional course-keeping ability.Furthermore,an expanded range of wave direction sets a stricter but potentially necessary requirement,while using the self-propulsion factors at low speeds can eliminate the unnecessary conservation of assessment result caused by those at design speed.

文摘[Objectives]To identify the drought resistance of main wheat varieties in Shandong Province and screen suitable cultivars for dryland cultivation.[Methods]Employing eight varieties including Jimai 60 as test materials,this study simulated drought stress using 20%PEG-6000 and measured changes in germination-stage indicators.A comprehensive evaluation was conducted using the membership function method,incorporating relative coleoptile length,relative germ length,relative radicle length,relative germination rate,relative germination potential,and stress germination index.[Results]Drought stress not only reduced wheat seed germination rate but also inhibited the growth of the germ,coleoptile,and radicle.The D values of the eight varieties were ranked as follows:Jimai 60>Linmai 9>Yannong 999>Shannong 30>Shannong 28>Luyuan 502>Yannong 1212>Jimai 22.Based on D values,the eight dominant wheat varieties were classified into three categories:highly drought-resistant varieties(Linmai 9 and Jimai 60),moderately drought-resistant varieties(Yannong 999 and Shannong 30),and sensitive varieties(the others).Linmai 9 and Jimai 60 are recommended as suitable wheat varieties for dryland cultivation in Shandong Province.[Conclusions]Drought stress induced by 20%PEG-6000 reduced germination rate,germination potential,and germination index of wheat varieties while inhibiting the growth of coleoptiles and radicles.These indicators can provide a preliminary assessment of drought resistance in wheat cultivars.However,since filter paper was selected as the growth medium,root length measurement errors were introduced during root washing,leading to variations in final experimental results.Futuer studies could attempt using sterilized sand as an alternative growth medium.
文摘Both China and Indonesia are influential maritime powers in the Asia-Pacific region.Strengthening practical maritime cooperation is highly significant to both sides as an important component of comprehensive strategic cooperation.Maritime cooperation has become a prominent part of the“five pillar”cooperation framework between the two countries alongside political,economic,people-to-people exchange,and security,playing a positive role in elevating the China-Indonesia comprehensive strategic partnership to a higher level.
