为了定位向日葵体细胞胚基因和筛选相关标记用于辅助育种,以31个重组自交系为材料,利用下胚轴表皮细胞诱导体细胞胚,获得了与体细胞胚发生率相关的,位于第5、10、13连锁群上的3个QTL位点,可分别解释表型变异的14.61％、10.04％和14.07％.同时,获得了与每块胚数相关的9个QTL位点,分别位于第2、8、10、11、12和19连锁群上,可解释表型变异的6.64％～16.96％,其中4个QTL位点位于第10连锁群上且位置相邻（在34.57 ～ 47.1Ocm之间）,可解释表型变异的40.39％.为了验证所获结果,在31个重组自交系中,筛选出2个体细胞胚发生率高的株系和1个低的株系杂交,构建了2个F2分离群体.利用AFLP和SSR标记对F2群体进行扫描,在与体细胞胚发生率相关的第5、10、13条连锁群上分别增加了24、6和18个新标记,标间距从6.80 ～11.40cm缩短到5.10～5.60cm.通过对F2群体与亲本基因型进行QTL区域的对比分析,预选出7个体细胞胚发生率高和7个低的株系,利用F3家系诱导体细胞胚进行验证.结果表明,预选结果与实际获得的结果完全一致,控制向日葵每块胚数的基因主要位于第10连锁群上,控制体细胞胚发生率的基因主要位于第5、13连锁群上;4个AFLP标记（e32m50-1、e38 m49-2、e40m49-1、e32m62-10）是最靠近控制体细胞胚发生基因的标记,可以作为该性状的辅助选择标记.

综合运用地球物理和土壤气剖面识别活动断层:以西班牙东北部比利牛斯山脉的阿梅尔(Amer)断层为例(Ⅰ)

作者： marianna A.Dudareva vlada v.Nikitina Russian Language Department Peoples‘ Friendship University of Russia (RUDN) Peoples‘ Friendship University of Russia (RUDN)

The article deals with the concept of "apophaticism" which is relevant not only for theology but also for philosophical and philological knowledge. The linguists are interested in apophaticism of the language, which primarily refer to vocabulary. During the last decades of hermeneutics development, the literary scholars also actively referred to apophatic tradition. The need to develop the idea of Russian poetry as an apophatic one is long overdue and it requires new approaches and works. The object of this article is the Soviet times and the thaw period with its binary formations;and the song "moscow Nights" by m. matusovsky is in the center of linguistic and philosophical research. much attention is paid to text fragments with verbal negation.

地球物理和土壤气组成探查相结合的方法可以快速低成本地获得有关地震活动情况的信息。本研究中,对西班牙的比利牛斯山脉(Pyrenees)的阿梅尔(Amer)镇附近明显存在新断裂的两个区域进行了地球化学土壤气采样(^(222)Rn,220 Rn和CO_2)、电阻率层析成像和地震折射数据分析。数据分析清楚地揭示了沿电成像剖面每个特定位置的气体异常值。地貌与水文地质资料、综合地球物理数据和土壤气测量结果表明:1在高渗透率的主断裂区域,变质沉积基底岩会释放出内生气体氡(^(222)Rn)和二氧化碳(CO_2),而下新生代碎屑沉积地层则表现为一个不透水的边界;2氡浓度最高(52kBq/m^3)的区域对应于Amer断层内近期在地貌上有较多活动证据的地区,更准确地说,是被较薄地表物质覆盖的地区;3最低的^(222)Rn值(0.2~0.4kBq/m^3)只在主要活动断层面记录到。这可以用高土壤CO_2射流(每日267g/m^2)的稀释作用来解释;4高地表破裂区域的土壤钍射气(^(220)Rn)活动性最大(143kBq/m^3);5地下水开采可能引起重要的自然流体动力和测量的气体浓度畸变。不同数据结果(地球化学、地球物理和水文地质)与实地观测结果(地质和地貌)的一致性为我们提供了一个初步的研究区构造-重力模型。

使用球对盘式摩擦计,在法向载荷为3~30N(对应最大赫兹接触压力为816~1758mPa)的条件下,研究Ti6Al4v合金在磷酸盐缓冲液中对磨氧化铝的摩擦腐蚀行为。纳米硬度测试结果表明,在纯磨损和摩擦腐蚀表面形成加工硬化层。在纯磨损过程中,当法向载荷从15N增加到30N时,表面硬度提高约100%;然而,当法向载荷为30N时,产生的磨屑越少,磨损率越低。在不同法向载荷下,腐蚀的存在使磨损率增加28%~245%。与静态相比,在摩擦腐蚀过程中,极化曲线获得的腐蚀电流密度增加3个数量级,且开路电位(OCP)向负电位方向偏移。由氧和磷化合物组成的摩擦膜不断形成和消除,使OCP曲线达到峰值,并使法向载荷高于3N时的摩擦因数波动减小。

Binuclear and hexanuclear titanium complexes stabilized by tetradentate [OOOO]^(4–)-type ligand were active in ethylene polymerization in the presence of Et2 AlCl/Bu2 mg binary co-catalyst, giving high molecular weight polyethylene. The binuclear complex showed significantly higher catalytic activity and thermal stability in comparison to mononuclear analogue. Ultra high molecular weight polyethylene(UHmWPE) samples were processed by a solid-state uniaxial deformation into high-strength(up to 2.5 GPa) and highmodulus(over 100 GPa) oriented film tapes, which indirectly indicates a low degree of entanglements between the macromolecular chains.
