The mechanisms of the electrochemical reduction and nucleation process of B（Ⅲ） on the platinum electrode in the LiF-NaF-KF-KBF4 molten salt at 700℃ were first investigated using cyclic voltammetry and chronoamperometry techniques. It was found that the electrochemical reduction of B（Ⅲ） occurs in single-step charge transfer： B（Ⅲ）＋ 3e → B, and the cathode process is reversible. The electrocrystallization process of B（Ⅲ） is instantaneous.

数字技术创新是新质生产力的组成部分,出口产品质量升级是高质量开放发展的基本要求。聚焦数字技术创新对出口产品质量的影响,从而探讨新质生产力促进高质量发展的渠道、机制和障碍,理论分析表明:数字技术创新降低资源投入、提升资源效率影响在位企业产品质量、临界企业产品质量和整体平均产品质量,对平均产品质量的影响具有不确定性。实证分析发现,数字技术创新自身难以提升平均产品质量,但与传统技术创新交叉项却显著稳健为正,这体现了数实融合、新旧融合的必要性;这一作用对中高技术产品并不显著,意味着中高技术产品质量升级可能更依靠技术创新质量;上述结论在考虑测量误差、样本选择、内生性等因素后依然显著。促进数字技术创新与传统技术创新融合是提升产品质量、促进高质量发展的关键,新质生产力无法孤立于旧生产力而发挥作用。

This paper is concerned with coupled linear forward-backward stochastic differential equations(FBSDEs,for short).When the homogeneous coefficients are deterministic(the non-homogeneous coefficients can be random),we obtain an L^(P)-result(p>2),including the existence and uniqueness of the p-th power integrable solution,a p-th power estimate,and a related continuous dependence property of the solution on the coefficients,for coupled linear FBSDEs in the monotonicity framework over large time *** order to get rid of the stubborn constraint commonly existing in the literature,i.e.,the Lipschitz constant of σ with respect to z is very small,we introduce a linear transformation to overcome the difficulty on small intervals,and then"splice"the L^(P)-results obtained on many small intervals to yield the desired one on a large interval.
