The application of multimedia courseware in class embodies the modernization of education,which changes the traditional way of conveying information,and plays important role in the aspects of creating teaching atmosphere,motivating students,raising efficiency of teaching,changing students' role,enhancing learning results and fostering student's ability.
METHODS:Randomized stratified clustering was adopted to select 466 students from 10 classes and 3 departmentsof medical sciences,pharmaceutical sciences and nursing in Hunan Vocational College of Environment and Biology in May 2006. Healthy Living Style Scale edited by Liang Jing and SCL-90 were adopted to conduct group testing and comparing analysis.
Along the way, we recover theorems of Steinberg  and E.
Furthermore, the intrinsic definition is just the (now) well-known Crandall-Lions viscosity solution, modified in a natural way to accommodate measurable coefficients.
The main purpose of this paper is to give a procedure to "mollify" the low-pass filters of a large number of Minimally Supported Frequency (MSF) wavelets so that the smoother functions obtained in this way are also low-pass filters for an MRA.

The oscillatory behavior of functions with compactly supported Fourier transform is characterized in a quantified way using various function spaces.
In this note we present a very simple method of proving that some hyperbolic manifoldsM have finite sheeted covers with positive first Betti number.
The method applies to the standard arithmetic subgroups ofSO(n,1) (a case which was proved previously by Millson [Mi]), to the non-arithmetic lattices inSO(n,1) constructed by Gromov and Piatetski-Shapiro [GPS] and to groups generated by reflections.
(HereM3 denotes the vector space of 3×3 matrices over k andp>amp;gt;3.) The method of proof involves an induction, and is potentially of wide applicability.
The proof is based on a variant of Moser's method using time-dependent vector fields.
In the second part we apply this method to obtain pseudo-Riemannian homogeneous manifolds with real Killing spinors.
Because of the advantages of the high resolution, wide range, and highly automatic operation, the Raman lidar has become a new-style and useful tool to measure water vapor.
Single tree's sapwood scattering style and diurnal water consumption rhythm for different diameter classes were studied in a 48-year-old Quercus variabilis stand, water protection forest in Beijing.
Inverse kinematics analysis and numerical control experiment for PRS-XY style hybrid machining tool
The program for the PRS-XY style hybrid machining tool in accordance with the program manner for the common numerical control (NC) machine tool was made.
Meanwhile, based on the ideas from CAP (Certified Assembly Programming) and SCAP (Stack-based Certified Assembly Programming), a reasoning framework was built to verify the properties of object code in a Hoare style.
