Level set method introduced by Osher and Sethian is a numerical method, which translates the problem of evolution of 2-D (3-D) close curve into the evolution of level set function in the space with higher dimension. Level set is an accurate and steady algorithm; it can treat with the change of topology naturally.

水平集方法是由Osher和Sethian提出的一种数值计算方法，它将二维的闭合曲线的演化问题转化为高维空间中水平集函数曲面演化的隐含方式来求解，具有拓扑结构可自然变化、计算精度高、算法稳定的特点。

Indicators, such as Per Capita GDP, development level of the third industry, level of transportation, medicine and telecommunication facilities, living environment, residents education level, and etc., which can reflect the economy, infrastructure, and people's living quality of the construction of the urbanization of Chinese cities in the comprehensive evaluation index system, have been used in the study and the all sidedness and availability of data are considered as well.

为兼顾指标的全面性和数据的可得性，可选用包括人均GDP，第三产业发展水平，交通、医疗、通讯设施水平，生活环境和居民受教育程度等反映经济、基础设施和人民生活质量现代化水平三方面的指标构建我国城市化进程的综合评判指标体系。

Moreover, MANGO, BENETTON, SISLEY also separately will open 90 level ground, 70 level ground, 50 level ground Dadian.

另外，MANGO、BENETTON、SISLEY也将分别开出九十坪、七十坪、五十坪大店。

Ma 5(subscript 1-4) submember is an asymmetric long-term base level cycle which can be divided into five middle-term base level cycles and more than 26 short-term base level cycles.

马五(下标 1-4)亚段构成了一个长期基准面下降半旋回，其又可划分为5个中期基准面沉积旋回及多于26个短期基准面沉积旋回。

From this study, both low hCG and high hCG are adversity to pregnancy, hCG level reflect the growth and function situation of trophocyte which is the main component of placenta, whereas, the level of steroid hormone which close to hCG directly influence whether pregnancy will maintain, but in some cases being short of oxygen in uterine placenta local, usually display hCG level higher than normal pregnancy.

在正常妊娠时hCG过低往往预示着流产的可能，从本研究结果看，可能不仅仅是hCG水平过低对妊娠不利，hCG水平很高对妊娠也不利。hCG水平的高低反映了作为胎盘主要组份的滋养细胞的生长情况与功能，而与hCG水平高低密切相关的类固醇激素的高低直接影响了妊娠能否持续下去。

There are three obvious diachronic levels in the pronunciations of the MC voiced initials in Min dialect nowadays: the unvoiced aspirated level, the unvoiced unaspirated level and the voiced level.

中古全浊声母字闽方言今读有清化送气、清化不送气和保留浊音三个不同的历史层次。

The term was originally introduced to indicate a drug that reduced evidence of processes thought to underly the disease, such as a raised erythrocyte sedimentation rate, reduced haemoglobin level, raised rheumatoid factor level and more recently, raised C-reactive protein level.

这个词最初是表明了一种药物，降低过程的证据认为underly疾病，如引起血沉，降低血红蛋白水平，提出了类风湿因子水平和最近提出的C -反应蛋白的水平。

The investigations in this thesis focus on several aspects as follows: We investigate the method that how to produce permutation matrix by using chaotic map, and get the method of image permutation based on chaotic map. This method can make original image to unorderly image to protect the true content of image. We investigate gray level mix function, and put forward a gray level mix function based on chaotic map. Because this function has chaotic characteristics, the image dealed with this function has very uniform histogram. Aiming at the contradiction between error robust and security on image encryption, we put forward a kind of gray level mix function including diffusion mechanism.

本文的研究工作主要集中在以下几方面：研究了如何利用混沌映射产生置乱矩阵的方法，给出了基于混沌的数字图像置乱方法，该方法能够将原始图像变成面目全非的杂乱图像，从而保护了数字图像的真实内容；研究了灰级混合函数，提出了基于混沌的灰级混合函数，由于该函数具有混沌特性，所以经过该函数处理后的图像具有非常均衡的灰级直方图；针对图像加密的错误鲁棒性与安全性之间的矛盾，提出了一种含有扩散机制的灰级混合函数。

For adjusting lipid metabolism,the level of TG in each treatment group was reduced a lot(P＜0.01).EAV(2.0g/kg) reduced TG\'s level from 1.68±0.05mmol/L to 0.86±0.03mmol/L,the level was lower than BIF(0.61±0.02mmol/L).

对脂代谢功能的调节方面，各治疗组TG含量都有大幅度的降低(P＜0.01)，其中鹿茸醇提物2.0g/kg的疗效最好，其TG由1.68±0.05mmol/L降至0.86±0.03mmol/L，低于联苯双酯(0.61±0.02mmol/L)。

You can snipe the second and third union leaders from this position.

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
