Clinical study on continuous drainage of cerebrospinal fluid to treat intracranial Infection

Clinical understanding of auxilliary cure of severe craniocerebral trauma by use of continuous drainage of subarachnoid lumbar

Objective To observe the efficacy of continuous drainage with central venous catheters,both intrathoracic cavity and intravenous chemotherapy in treatment of malignant hydrothorax.

In the framework of free electron approximation,the analytical results of persistent currents and energy spectra of one-dimensional spin-dependent mesoscopic ring driven by time-dependent electric fields have been given.

Based on an exactsecond guantized Hamiltonian of non-interacting electron gas in the mesoscopic ring mixed withAB,AC effect,analytic solutions for energy eigenvalues, the persistent current and Dersistentspin curreut are obtained It is shown that AC effect is extremely important for electrons in somesemiconductors applied with intense electric field.

The persistent current and the quantum energy spectrum in mesoscopic metal dual rings;

The persistent current in a mesoscopic Aharonov-Bohm ring with a series-coupled double quantum dot;

Influences of a magnetic field on the persistent currents of mesoscopic coupling metallic ring;

Based on quantum waveguide theory,the effect of impurities on the transmission probability and the persistent currents in mesoscopic structure is studied.

The persistent currents in one dimensional non metal mesoscopic ring are studied using Zou Andersons Slave Fermion method with large U Hubbard model at heavy doping condition.

The one-dimensional normal metal mesoscopic ring, which was affected by dis-order in an inhomogeneous field, is studied, The conclusion that of f-diagonal decreased the amplitude of persistent currents more than diagonal disorder is obtained.
