This paper analyzes the problems existing in the technological innovation of Chinas private enterprises, and puts forward the countermeasures to improve the management informatization level of Chinas private enterprises. In order to promote the information construction of economic management of Chinas industrial and commercial enterprises, we must strengthen the attention of government leaders to scientific and technological innovation, build a high-quality talent team, take scientific and technological innovation as an important strategy of enterprise management, and promote the healthy and sustainable development of enterprises.展开更多

In this regard, the government departments should take the lead to vigorously carry out the sampling of atmospheric sulfur dioxide. In order to ensure the quality of the sampling work, detailed analysis should be made before, during and after the sampling, and advanced technologies and supporting facilities should be introduced to record the information and data generated in each link in detail. All these can provide an important reference for the ecological environment management and protection.展开更多

The system is composed of an aqueous droplet supported at an Ag/AgCl disk electrode and it was covered with an organic solution. In this manner, a conventional three-electrode potentiostat can be used to study the ionizable drugs transfer process at a liquid/liquid interface. Physicochemical parameters such as the formal transfer potential, the Gibbs energy of transfer and the standard partition coefficients of the ionized forms of these drugs can be evaluated from cyclic voltammograms obtained. The obtained results have been summarized in ionic partition diagrams, which are a useful tool for predicting and interpreting the transfer mechanisms of ionizable drugs at the liquid/liquid interfaces and biological membranes.展开更多

Under appropriate assumption, it is shown that the perturbed solution to parameterized VIP is existent, unique, continuous and differentiable with respect to perturbation parameter. In the case of differentiability, we derive the equations for calculating the derivative of solution variables with respect to the perturbation parameters.展开更多
