The full-length genomic DNA of MCAT (Malonyl-CoA:acyl carrier protein transacylase) in Brassica napus was cloned. BnMCAT shares very high identity with AtMCAT in gene sequence and gene structure. A multiple alignment of the protein sequence showed that BnMCAT shares high identity with other MCATs from E. coli and plants. BnMCAT was expressed in all tissues, such as roots, stems, leaves, flowers, and seeds, and no significant differences in the expression level were found in different embryo stages after pollination. According to an in vitro relative activity analysis, purified recombinant BnMCAT expressed in E. coli had transacylase activity. Although the relative activities of BnMCAT in crude extracts isolated from different staged embryos were similar and showed little variation, a higher relative activity was found in a crude extract isolated from embryos in comparison to leaves. Different relative activities of BnMCAT in crude extracts isolated from cultivars with different oil content were also found, suggesting that the activity of BnMCAT might be a decisive factor for a high oil content. Together, these results showed that BnMCAT is an important enzyme in the FAS system and indicate that BnMCAT might be a new target enzyme for future crop improvement through genetic engineering.

中国具有国土广袤、幅员辽阔的特点，世界上两大地震带-环太平洋地震带和欧亚地震带在中国交汇，地震断裂发育，在全球范围来讲，中国地震活动最为强烈、地震灾害后果严重。汶川映秀地震引发了大量的滑坡、崩塌等次生地质灾害，据估计整个灾区地震触发的崩塌、滑坡有5万处以上，潜在泥石流沟近千条，而对人民安全造成直接威胁的灾害隐患点就达12000余处，具有分布广泛、类型复杂、破坏巨大的特点。地震造成了山体大量开裂，间接形成大量松散性质的堆积体，引发大量斜坡潜在的不稳定，这个过程隐蔽性强，易于构成灾害威胁，同时数量难以估计。在一定的适宜条件下，这些潜在不稳定斜坡将诱发突发性泥石流，严重威胁人民群众生命财产。因此，采用新技术新方法快速查明重灾区突发性泥石流隐患分布及性状特点，并对其进行危险性区划和预警预报，有重要科学意义和实用价值。松散堆积物的大规模分布是构成泥石流的物质基础。在地震引发的大量次生灾害间接和直接的产生了大量的松散固体堆积物位于坡面上，预计在今后一段时期内，地震灾区泥石流爆发的规模和频率将显著增加，专家保守估计地震的影响也将持续20年左右。据国土资源部门调查，仅四川灾区已查出具有潜在危险的泥石流沟805处。许多研究表明，降水是诱发泥石流灾害的主要因素，研究降水与泥石流的关系是开展泥石流预报、区划和灾害防治的重要步骤。泥石流的发生与降雨有莫大的关系，但是并非所有的降雨都能激发泥石流。降雨量是一个时间尺度上的积分值，对于同一个地区，可以测量记录并研究它的年降雨量、季节降雨量、月降雨量、旬降雨量、日降雨量，甚至在更短的时间尺度上比如小时等。已经证明年降雨量与泥石流发生的关系不甚密切，无法用年降雨量来刻画泥石流的发生规律。从另一个角度来看，泥石流的发生是短暂的进程，与它有关的降雨量也必定被控制在一个有限的时间尺度上。与泥石流有关系的降雨量被认为是由前期降雨和短历时雨强组成的，如果能够计算出具体的雨量，对于泥石流预防和治理的意义是不可估量的，将在很大的程度上减少人民群众的生命财产损失。但是，由于降雨与泥石流爆发的规律存在天然复杂性，同时估算泥石流爆发的前期降雨和短历时雨强具有较大难度，是当前泥石流研究的热点方向之一。泥石流是一种非常复杂的自然现象，很难对，目前针对泥石流的模拟方法很多，但是泥石流的启动问题比较复杂，泥石流的爆发所存在的时间动态性、空间异质性和不确定性，泥石流的模拟问题具有天然复杂性，使得泥石流的精确模拟受到很大的限制。元胞自动机是一种典型的框架式的时空离散动力学模型，由于它自下而上的特点，在模拟泥石流、滑坡、火山熔岩流等复杂自然现象、地表过程方面有巨大的潜力和优势。本文采用元胞自动机等计算机仿真模型，模拟计算了不同情况下的临界雨量，有利于揭示在特定的地理条件下前期降水引发泥石流的可能性，计算结果显示，研究区内，爆发泥石流的前期雨量（24h）在60mm-110mm左右，短历时雨强（10m）在15mm-45mm左右，这都在当地可能降雨范围内，显示出研究区内的多条潜在泥石流沟都存在爆发的可能性。最后，本文利用地形信息熵分析了研究区的泥石流危险性，并比较了两个研究的结果，显示元胞自动机的模拟结果具有一定的可用性与准确度。本文讨论的方法与结果为灾区泥石流预报提供有价值的信息。

劳动与个体自我实现之间处于何种关系,这在当代批判资本主义工作制度的浪潮中被重新提出。部分具有分析背景的英美马克思主义学者通过重释自由王国等相关论述,发现马克思似乎并没有一贯地支持“劳动促进自我实现”命题,并给出了“转向”“震荡”“一致”的三类解读径路。但事实上,自由王国的自由得以成立的条件正是必然王国中的自由存在。后者不仅对于共产主义的社会整体构建而言是基础性的,而且对社会成员的特殊个性实现也是必要的。重新反思马克思对必然王国中自由的论述及其与社会个体自我实现的关系,有助于我们把握住马克思与当代主流政治哲学的决定性分歧以及解决方案上的特有优势。

岩溶区面积约占中国国土面积的三分之一，包括云南在内的整个西南地区石灰岩连成一片，面积共达55万km。岩溶发育致使工程场地地质条件大为恶化，容易产生建筑地基塌陷、水库渗漏等问题。拟建机场地处碳酸盐岩裸露区，岩溶发育程度较高。研究岩溶发育规律及其工程效应，对指导机场建设显得异常重要。本文在充分了解前人岩溶研究的基础上，通过现场大比例工程地质测绘、物探、钻探、岩土体物理力学实验、模糊综合评判、FLAC数值模拟等，系统研究拟建机场岩溶发育特征、分布规律、发育机制及岩溶地基的稳定性，主要取得了以下结论和研究成果： (1)研究区处于南北走向的台地分水岭部位，岩溶发育以垂向为主，总体发育中等，槽谷等地带强烈发育。 (2)场址西南端为石芽残丘岩溶地貌，中部为溶蚀侵蚀峰丛岩溶地貌。总体上，前者的岩溶发育程度高于后者。地表岩溶表现为石芽、溶沟溶槽、岩溶漏斗、落水洞等，地下岩溶以裂隙型溶洞、强溶蚀带、土洞为主。溶沟溶槽、石芽遍布整个场区;漏斗、落水洞总共发育69个，线密度一般3m个/km;溶洞以裂隙型为主，钻孔遇洞率23.59%，岩溶率5.99%;土洞零星分布。 (3)平面上，自南西至北东岩溶发育程度逐渐降低。岩溶漏斗、落水洞常呈线状、串珠状定向排列，石芽残丘区最为发育;存在7个溶洞集中分布区，间隔30000m，强溶蚀破碎带呈SN向的条带状展布。 (4)垂向上，岩溶发育层状分布显著。1780m附近，漏斗、落水洞发育;1780810m高程段溶洞、溶蚀带最为发育，向两侧逐渐递减。 (5)岩溶的发育受岩性、地质构造、新构造运动、气候、岩溶水控制。岩石溶解形式主要为白云质灰岩的不均匀溶蚀;南北向岩溶形态最为发育，表现出“多层性”、“叠加性”和“分带性”，岩溶地貌在平面上沿沟谷分带;剖面上位于垂直渗流带，垂向溶蚀强烈。 (6)岩溶地貌纵向上表现为多旋回岩溶迭加发育的特点，一个岩溶期内可划分为原始地貌、溶隙—溶沟、峰丛谷地、峰林谷地、溶丘谷地、溶原几个阶段;横向上同期异形，西南端、中部差异显著。 (7)岩溶发育机制方面：溶洞由溶隙发展而来，沿节理面或层面发育，具有狭长状特点;影响土洞形成的最大因素是地下水的动态变化，临界水位波幅Hcr及临界流速vcr是引起土洞发育的重要参数，软塑土体中土洞更易形成;漏斗、落水洞主要有溶蚀型及塌陷型两类，以溶蚀型为主。 (8)采用模糊综合评判法对岩溶地基进行稳定性评价，溶洞基本处于较稳定定状态，占88.9%(90%)。《民机规范》的评价结果稳定状态的溶洞占71%，但由于该规范考虑重点是“溶洞顶板坍塌后自行填塞程度”，而计算本身却未考虑溶洞的充填程度，计算结果偏保守。对《民机规范》评价稍作修正后认为处于稳定状态的溶洞达91%，与模糊综合评判结果具有较好的一致性。 (9)FLAC数值模拟结果认为埋藏浅、顶板破碎的溶洞围岩应力集中、塑性区明显，位移量大，灌浆的治理效果明显优于跨越方式治理。
