浅析辩护人、诉讼代理人毁灭证据、伪造证据罪

现行刑法第306条专门规定了辩护人、诉讼代理人毁灭证据、伪造证据、妨碍证据罪。本罪的主要特征犯罪主体、犯罪客体、犯罪主观方面、犯罪客观方面不同于一般主体的犯罪。同时，从我国刑法第306条这一专门刑事条款违背公正性原则，构成对律师职业的歧视，破坏司法平衡，恶化控辩双方关系，在实践中不利于刑事诉讼法的实施．不利于民主法制建设等方面对此罪名进行了质疑，主张此罪名应予废止。     

基于本体的空间信息集成

提出了将本体的思想和方法引入到空间信息集成的思路,以解决当前地理信息系统中的各种异构问题.研究了地理本体模型的建立和表示,并在此基础上提出了一种面向空间信息集成的地理本体比较方法,其核心思想是从结构和语义两个方面对地理本体中的概念进行比较,其中从结构方面对概念进行比较主要是对概念的名称进行比较,而从语义方面对概念进行比较主要是确定在地理本体中概念之间的语义关系.     

Feedforward and feedback optimal control for linear time-varying systems with persistent disturbances

1 .INTRODUCTIONIn nature ,there are various external disturbancesaffecting the performances of systems . Many con-trol problemsinvolve designing a controller capableof stabilizing a given linear system while mini mi-zing the worst-case response to some additive dis-turbances . This problemis relevant to disturbancerejection and cancellation. One application area ofinterest is flight control through wind shear ,where disturbances arise from a modal for windshear based on harmonic oscillati…     

英文电子书信写作中的"合作"与"礼貌"策略

本文认为在电子书信这一书面语交际方式中,与口语交际的情形类似,写信人应遵守交际规则。一方面写信人需采用“合作”策略,及时回复,确保信息充分、相关、真实有据、表达清晰简明;另一方面,写信人还需考虑礼貌因素,在整体风格、语篇、句法、词汇各个层次上,运用面子维护策略来缓和或弥补言語行为对面子的伤害。     

含不同侧氨基密度的PLGA-（ASP—Diol）-PLGA共聚物合成与表征

以N-（苄氧羰基）-L-天冬氨酸和亚硫酰氯反应制备了N-苄氧基天冬氨酸酐，然后将其与不同链长的二醇（Diol：乙二醇、二缩三乙二醇、聚乙二醇200和600）缩聚，合成含端羟基的天冬氨酸-二醇交替预聚物[ASP—Diol]；分别以它们为大分子引发剂，辛酸亚锡为催化剂进行丙交酯／乙交酯（LA/GA：75／25）开环共聚，合成系列含侧氨基的天冬氨酸-二醇-聚乙丙交酯[PLGA-（ASP—Diol）一PLGA]多元三嵌段共聚物。利用FTIR、1HNMR、EA、DSC和GPC对共聚物结构进行了表征。结果表明，影响预聚物分子量的主要因素不是二醇的分子量，而是其端羟基的活性。但随着二醇链段长度增加，多元共聚物中氨基含量降低，玻璃化温度也明显下降。因此，通过改变二醇链段的长度（或分子量）可以有效控制PLGA-（ASP—Diol）-PLGA中侧氨基的密度及分布。

Synthesis and properties of a Pr（Ⅲ） complex with 2-acetylbenzimidazoledehyde-glycine Schiff-base ligand

Abstract The 2-acetyl-benzimidazoledehyde-glycine Schiff-base ligand and the corresponding Pr（Ⅲ） complex Pr2L3（NO3）3· 2CH3OH （L=C11H10N3O2） were synthesized in methanol and characterized by a series of methods, including chemical analysis, elemental analysis, TOF-MS, ^1H NMR, UV-, IR-, Raman spectra, thermal analysis, and the three-dimension fluorescence excitation and emission spectra. The Pr（Ⅲ） complex exhibits extraordinary water-solubility and the Pr（Ⅲ） hydroxide appears at pH≥13. The complex also possesses specific fluorescent properties. Thus, at the excitation wavelengths 200.0-280.0 and 260-350 nm the fluorescence bands were observed at 290.0 and 400.0 nm, respectively.

Synthetic seismograms of ground motion near earthquake fault using simulated Green’s function method

Seismograms near source fault were synthesized using the hybrid empirical Green＇s function method where the discretely simulated seismic waveforms are used for Green＇s functions instead of the observed waveforms of small earthquakes. The Green＇s function seismic waveforms for small earthquake were calculated by solving wave equation using the pseudo-spectral method with the staggered grid real FFT strategy under a detailed 2-D velocity structure in Kobe region. Magnitude and seismic moment of simulated Green＇s function waveforms were firstly determined by using the relationship between fault length and corner frequency of source spectrum. The simulated Green＇s function waveforms were employed to synthesize seismograms of strong ground motion near the earthquake fault. The synthetic seismograms of the target earthquake were performed based on the model with multiple source rupture processes. The results suggest that synthesized seismograms coincide well with observed seismic waveforms of the 1995 Hyogo-ken Nanbu earthquake. The simulated Green＇s function method is very useful for prediction of the strong ground motion in region without observed seismic waveforms. The present technique spreads application field of the empirical Green＇s function method.
