This paper attempts to explore the functional divergence of LD （Left Dislocation） in English and Chinese. Through detailed analyzing, we find that LD in both languages shares only one function, the function of simplifying, but it is different in other functions and there are eight more functions in Chinese than in English. The interface study of LD in the two languages leads to the implications： The connections between syntactic form and discourse function are language-specific and arbitrary, and LD serves a wide variety of discourse functions and is motivated by a range of discourse circumstances

Acute and chronic subdural hygromas are common postoperative clinical complications of ventricularshunting, arachnoid cyst marsupialization and arachnoid cyst resection.^1 This article introduces a case of subdural hygroma after resection of a space-occupying lesion in the left lateral ventricle that resulted in compressive brainstem deformation and reviewed the recent related literature. The conclusion is that in related surgical procedures, prevention of rapid cerebrospinal fluid loss and excessive fluctuations in intracranial pressure are especially important.

A stable,efficient,and economical bifunctional electrolytic catalyst would be incredibly beneficial for the development of hydrogen production by electrocatalytic water *** this study,we synthesized a novel MnS–MnO heterogeneous nanocube@N,S-doped carbon(MnS–MnO@NSC).MnS–MnO nanocubes possess rich heterogeneous interfaces and plentiful catalytic active sites to promote electrochemical reactions,while the N,S-doped carbon shell possesses excellent conductivity and catalytic properties and protects the ***–MnO@NSC exhibited excellent electrochemical properties as an effective bifunctional electrocatalyst for the hydrogen evolution reaction(HER)and oxygen evolution reaction(OER)in KOH *** the HER,the overpotential was as low as 124 mV at a current density of 10 mA·cm^(-2)while in the OER,it was only 340 mV at 100 mA·cm^(-2)under the same *** addition,a MnS–MnO@NSC||MnS–MnO@NSC electrolyzer exhibited almost comparable activity and higher steadiness than those exhibited by the state-of-the-art Pt/C||RuO_(2)/C system for full water splitting in KOH solution.
