为深入探究数字化转型与制造业绿色技术创新之间的关系,本文以2013~2023年全国制造业为研究对象,开展制造业数字化转型与绿色技术创新的关系实证研究。以制造业绿色技术创新效率为因变量,以制造业数字化转型水平为自变量,以行业规模、资本强度、融资能力、外资投入比、技术成熟度为控制变量,通过回归分析、稳健性、异质性检验等,验证因变量与自变量之间的关系。结果表明:数字化转型显著促进了制造业绿色技术创新,且行业规模越大和资本强度越强的制造业,其绿色技术创新效率越高;数字化转型对出口依赖度、发展阶段、数字化来源、行业要素不同的制造业促进效果不同,对出口依赖度高、发展阶段靠前、国际数字化来源和高技术创新的制造业绿色技术创新促进作用更强;数字化转型可通过减少外部交易成本和提高市场竞争的方式,促进制造业绿色技术的创新。为提高制造业绿色技术创新,本文提出包含加强行业市场竞争力和加强政府监管等策略,以期能够更好地发挥数字化转型对制造业绿色技术创新的促进作用。

Stevioside（1）, an ent-kaurene glycoside commercially extracted from Stevia rebaudiana Bertoni is used as a non-caloric sweetener for food in many countries. The increasing demand for low calory and natural food contributes to the increasing popularity of that glycoside. It has recently been demonstrated that stevioside and its derivatives have inhibitory effects on the inflammatory ear edema of mice and suppress the tumor-promoting effect in mouse skin.

This paper presents a scheme of fault diagnosis for flexible satellites during orbit maneuver. The main contribution of the paper is related to the design of the nonlinear input observer which can avoid false alarm arising from the disturbance from orbit control force. The effects of orbit control force on the fault diagnosis system for satellite attitude control systems, including the disturbing torque caused by the misalignments and the model uncertainty caused by the fuel consumed, are discussed, where standard Lu- enberger observer cannot work well. Then the nonlinear unknown input observer is proposed to decouple faults from disturbance, Besides, a linear matrix inequality approach is adopted to reduce the effect of nonlinear part and model uncertainties on the observer. The numerical and semi-physical simulation demonstrates the effectiveness of the proposed observer for the fault diagnosis system of the satellite during orbit maneuver.

关键词： orbit control flexible satellite attitude control system,nonlinear unknown input observer (NUIO) fault diagnosis.

We introduce notions of continuous orbit equivalence and its one-sided version for countable left Ore semigroup actions on compact spaces by surjective local homeomorphisms,and characterize them in terms of the corresponding transformation groupoids and their operator *** particular,we show that two essentially free semigroup actions on totally disconnected compact spaces are continuously orbit equivalent if and only if there is a canonical abelian subalgebra preserving C^(∗)-isomorphism between the associated transformation groupoid C^(∗)-*** also give some examples of orbit equivalence,consider the special case of semigroup actions by homeomorphisms and relate continuous orbit equivalence of semigroup actions to that of the associated group actions.
