The Hausdorff measure for the level sets of multi-parameter symmetric stable processes has been obtained and the inner connection of the measures and local times for it has been demonstrated, which describes the fractal nature for the level sets of this kind of processes. As we know, it is always one of the focuses in the field of random fractal. The reasult of the existence and continuity of the local time for multi-parameter stochastic processes with stable components has been got in the project. Then we gained the measure for the random fractal sets such as the range and graph of this kind of processes. Furthermore, a progress besides the mentioned above in the project is that we have resolved the multifractal analysis of the sample paths for Brownian sheet, that is the multifractal decomposition of white noise in high dimension.

This dissertation involves the study of the growth dynamics of colloidal particles under unequilibrium and irreversibility condition. Firstly, it is of interest to investigate whether the ideal diffusion or reaction-limited aggregation universal behavior can be observed for the initially polydisperse practical system of basic yttrium carbonate as well. The fractal structure of basic yttrium carbonate aggregate cluster was observed using transmission eletron microscopy. The aggregation kinetics of basic yttrium carbonate colloids was studed using dynamic 1ight-scattering techniques. At 1.00mol/l NaCl solution the fast diffusion-limited aggregation behavior was observed with an increase in the aggregate size over time described by a power law. The aggregates are characterized by a fractal dimension D=1.82. The disordered and ramified cluster is consisted of primary colloidal particles and tenuous and more open. These are in good agreement with those observed for other colloidal system such as colloidal gold (1.86), silica (1.85) and polystyrene latex (1.82) in diffusion-limited aggregation from the static and dynamic light scattering by Lin. Therefore ideal diffusion-limited aggregation behavior can be observed in practical polydisperse system as well. Smoluchwski and fractal theories were used to obtain the aggregation rate constant for initially polydisperse system for the first time.
本论文研究胶粒的非平衡不可逆聚集动态学,分为两个部分,第一部分是通过实验研究一个新的初始多分散的碱式碳酸钇胶粒实际体系中,聚集标度性质的普适性,即使用透射电子显微技术观测聚集粒子簇的分形结构,使用动态激光光散射研究碱式碳酸钇胶粒的聚集动力学,胶粒带电而产生静电排斥作用使得碱式碳酸钇胶粒处于稳定状态,当加入电解质NaCl溶液时,碱式碳酸钇胶粒间的Debye-Hückel屏蔽距离缩短,从而降低静电排斥能垒,引起胶粒发生不可逆聚集,加入电解质NaCl的浓度为1.00mol/l时,碱式碳酸钇胶粒进行快速聚集,经历扩散控制聚集机理,形成结构疏松、更为开放的分形聚集粒子簇,其分形维数为1.82,碱式碳酸钇胶粒聚集增长动力学遵循幂函数增长规律,与Lin等使用静态激光光散射和动态激光光散射测量硅胶(1.85)、金胶(1.86)和聚苯乙烯胶乳(1.82)在扩散控制聚集状态形成聚集粒子簇的分形维数值以及粒子簇聚集增长的动力学规律相一致,表明胶粒聚集标度性质的普适性质在初始多分散的实际体系中也是存在的,首次由动态激光光散射的实验数据得到初始多分散胶粒分形粒子簇的聚集速率常数,并且其值与Smoluchowski聚集速率理论预期相符。

作者中文名:王健;邹义壮;唐丽丽;李杰;张东;金山;刘娟摘要:目的研究胃癌患者的生存期与个性特征、应付方式等心理因素,以及免疫功能的关系。方法对胃癌晚期患者、胃癌较长生存期患者及正常健康人分别进行明尼苏达多相个性测验、应对方式问卷、免疫功能测试,并做相关分析。结果(1)MMPI:胃癌Ⅱ组人格障碍评分(42.0±10.5)及社会内向评分(42.2±11.6),低于其他两组[胃癌Ⅰ组为(49.3±11.2)分和(48.3±9.4)分,对照组为(48.6±10.9)分和(39.9±11.5)分;P均<0.05];(2)CSQ:解决问题和求助因子分,胃癌Ⅰ组[分别为(0.68±0.27)分和(0.42±0.18)分]均低于胃癌Ⅱ组[分别为(0.82±0.18)分和(0.65±0.21)分;P<0.05和P<0.01],胃癌Ⅱ组更多采取成熟的应对方式;(3)自然杀伤细胞:胃癌Ⅱ组水平(21.4±9.2)高于胃癌Ⅰ组[(14.2±8.8);P<0.05];而NK细胞水平与MMPI的抑郁(r=-0.35)、人格障碍(r=-0.39)、偏执(r=-0.29)、精神衰弱(r=-0.30)及精神分裂(r=-0.30)等量表呈负相关,与CSQ的解决问题因子(r=0.35)及应付方式类型(r=0.34)呈正相关。结论与胃癌Ⅰ组比较,胃癌Ⅱ组更为外向,负性情绪较少,更多采取成熟的应对方式,其NK细胞水平较高,对胃癌的预后产生了积极的影响。

One transmission cell to another while maintaining the DVB-H service.· For a number of reception scenarios; indoor, outdoor, pedestrian and inside amoving vehicle, the transmission system shall offer sufficient flexibility and scalability to allow the reception of DVB-H services at various speeds, whilstoptimizing transmitter coverage.· As services are expected to be delivered in environments that suffer high levels of man-made noise, the transmission system shall offer the means to mitigate their effects on the performance of the receiving terminal.· As DVB-H aims to provide a generic way to serve handheld terminals in various part of the world, the transmission system shall offer the flexibility to be used in various transmission bands and channel bandwidths.
因此DVB-H采用分时方式的资料传送形式,把原本通道频宽是由其它节目共同分配享有的,现在只可以让某一个节目使用全部的频宽所以让节目传送的位元率提高了,相对的减少传送的时间,但跟DVB-T一样在单位时间内所传送的资料是一样多的,由於DVB-H采用分时多工的方式传送资料所以接收器只在该节目传送的时间内接收该笔资料,而其它时间则不接收然后在等一个单位时间内,该节目的资料再传送时在接收,如此开关开关达到收到整部节目的资料,并大量的减少持续接收节目所消耗的功率,接下来由於DVB-H采用4K正交分频多工编码的方式,虽然涵盖的范围没有DVB-T大但对高速移动的时候接收信号时的效果会比较好。
