Yu introduced in 1997 the localization Roe algebras , and shown that, to attack the Coarse Baum-Connes Conjecture, it suffices to prove that the local index map is an isomorphism from the coarse K-homology to the K-theory of the localization Roe algebras.

Yu受热方程方法的启发，引入局部化Roe代数，把粗Baum-Connes猜测的证明归结为证明从粗化K-同调群到局部化Roe代数的K-理论群的局部指标映射为同构。

With the fast development of the world trade and the technology of navigation, a vessel is becoming larger in size, higher in speed, more specialized in use and automatic in manoeuver; the seamen are much more multinational, and some sea areas are undergoing a heavier transportation pressure. All of these make the navigation environment worse and svessels manipulating ability lower, especially in those narrow channels.

但是，随着现代世界贸易和航海技术的飞速发展，船舶向大型化、高速化、专用化、自动化发展，船上配员向多国籍化发展，局部地区交通运输日益繁忙，尤其是在狭水道操纵安全，使得船舶航行环境变的恶劣和船舶运动性能也有所降低。

Influenced by tectonic movement, there were no sediments in the area from Oligocene to Miocene. Appearance of marlite in the Pliocene, especially in Yaqueling region, proved localized depositing environment forming, for which there had only few amount of terrigenous matters to supply. Sedimentary facies association of alluvial fan, fan delta and inland lake appeared at the early and middle stage of lower Pleistocene, and association of fan delta and inland lake appeared at the later stage of lower Pleistocene and the early stage of middle Pleistocene. Net-veined laterite appeared at the top of lacustrine deposit, which reflected pedogenesis taking place after the end of deposition. Such evolution history proves that there had no lager river system traversing this area before the early stage of middle Pleistocene.

对于江汉盆地西缘宜昌地区来说，其沉积及古地理演化表现为：早白垩世为受天阳坪断裂控制的内陆湖泊沉积环境，沉积中心在天阳坪断裂的北侧，此时几乎不存在来自黄陵地区的水系；晚白垩世同样为受断裂控制的内陆湖盆环境，但湖盆面积扩大、断裂活动减弱，且后期出现成化湖相沉积；第三纪早期盆地由断陷盆地转变为坳陷盆地，同时石膏的出现代表了局限咸化湖盆的存在；渐新世—中新世，受构造影响，缺失该时期的沉积；上新世时在鸦鹊岭一带出现的泥灰岩沉积反映了陆源物质供应不足的局限沉积环境的存在；早更新世早中期为冲积扇—扇三角洲—内陆湖泊沉积，早更新世晚期—中更新世早期为扇三角洲—湖相沉积，后期出现沉积结束以后的网纹红土化作用。

Wherein, the sludge has water content as 75~85% and bearing capacity less than 10KPa, has mephitis and obvious rheometric feature and small shear strength; the mineralized garbage has almost no harm and stable after buried for 8~10 years.

污泥为含水率75～85％、承压能力小于10KPa、有恶臭气味、流变性明显、抗剪强度小、遇水浸泡后呈膨润持水性、表面感官差的污水厂污泥；矿化垃圾为填埋了8～10年后已基本无害化和稳定化的矿化垃圾。

Regularization is often used to overcome the ill-posedness, and Tikhonov regularization is the most common regularization method, but this kind of regularization will cause the sharp edge of the reconstruction result to be blurred.

从数学上来说，超分辨率图像重建问题是一个病态问题，为了克服其病态性，需要对其进行规整化，其中最常用的Tikhonov规整化方法，但这种规整化会导致重建高分辨率图像边界被模糊。

Methylation is negative correlation with genetic transcription , and the mechanism is probably as follows : directly interfere the combination of specific transcripton and recognition site of each promoter ; mediated transcription inhibition by change the construction of chromatin; induced gene silencing by combination of methylation site and transcription inhibition. P16 gene is also called multiple tumor supresser gene , which is the best easily to methylate in the anti-oncogenes. P16 gene locates in 9p21 of mankind-chromatosome , and it's total length is 8.5kb .

甲基化与基因转录呈负相关，其机制可能是[3]：直接干扰特异的转录子和各自启动子识别位点的结合；通过改变染色质结构，介导转录抑制；甲基化DNA位点直接与转录抑制子结合，诱导基因沉默。p16基因又称为多肿瘤抑制基因( multiple tumor suppressor 1 ，MTS1) [4] ，是肺癌中最易发生甲基化的抑癌基因，该基因位于人类染色体9p21上，全长8.5kb ，由两个内含子和三个外显子组成。
