Objective To study the power spectrum density of blood flow ultrasonic Doppler signal using wavelet analysis. Method Doppler signal of blood flow in human common carotid artery was studied with wavelet scalogram analysis, an affine smoothing Wigner Ville transform with a constant "Q" character. Result Wavelet scalogram of blood flow ultrasonic signal had a higher distinguishability than STFT spectrogram in the low frequency portion, but had poorer decussation terms than spectrogram.

对于平稳信号的处理工具仍然是Fourier变换，但是，在实际应用中的绝大多数信号是非平稳的，现在看来处理非平稳信号的主要工具将是小波变换，这主要是因为传统的Fourier变换分析信号时，时间和频率分辨率精度是固定不变的，而利用小波变换分析信号，在信号高频段时间分辨率精度也较高，在信号低频段频率分辨率精度较高，这很符合非平稳信号的特点。

The research shows that asymmetry information can cause sluggish behaviour for the same type of employees, the exogenous layoff probability can restrain labour positivity and threaten the efficient labour of the employees, and reduce the agent cost. While endogenetic layoff probability cannot impact on the function of the assembled mechanisms consisting of promotion and fixed income under asymmetry information, which can avoid the moral risk of employees to achieve the same degree of their labour under symmetry information.

研究表明：非对称信息会诱导同类员工偷懒行为，外生裁员概率抑制员工的劳动积极性，对员工的有效劳动构成一种威胁，但裁员概率降低了代理成本；外生裁员机制并不影响信息非对称下的晋升激励和固定收入组合机制持有的避免员工道德风险的功能，实现员工对称信息下的努力程度；以绩效评估为特征的内生裁员机制能够促使异类员工更加努力工作，提高产量，相应地也增加了工资支出；高能员工比低能员工更努力，提高员工裁员绩效标准和高能员工比例，有利于降低代理成本。

From actual receiving state, increasing differentiation of the TV embracer" s demands and the incertitude of receiving behaviors will make the two conception of the borderline out of focus. All of these have established realistic base on research of "Non-prime time of TV.

In the first part, the thesis firstly constructs the production possibility sets deduced from constant, nonincreasing, nondecreasing and nondetermined returns to scale. Based on the above point, the thesis systematically deduces the models of DEA which evaluate production efficiency for exogenously fixed inputs and the models of ADEA (Allocative Data Envelopement Analysis) which evaluate cost, revenue, profit efficiencies and allocation efficiency in production possibility sets, and then discusses the solution properties of these mathematics models.

The results show that the amorphous PLGA fiber with porous structure (0.1-1.0 μm) is obtained by diluted solvent spinning method and the mechanical properties is affected by pressure and temperature. Bending strength and shearing strength of the samples increase firstly and then decrease with the increase of molding temperature and pressure. While the molding temperature is 160℃and the pressure is 105MPa, the PLGA materials possess optimal mechanical properties, bending strength, shearing strength and bending modulus 187.3 MPa, 100.0 MPa and 2.5 GPa, respectively. The mild temperature molding PLGA materials are desired to play a grate role in non-bearing internal fixation devices.
