论新世纪长篇小说“文革”叙述的话语形态
,
- , 2016,
Abstract: 在市场化与消费主义语境中,“文革”历史在可资写作的同时,亦成为了消费娱乐的文化资源。新世纪长篇小说的“文革”叙述在书写方式与表达策略上,呈显出鲜明的消费主义话语形态。以“性+革命”作为想象“文革”历史的一种定式,渲染文革时期“性爱奇观”;回叙“文革”的青春记忆时,聚焦于重构自由快乐与浪漫纯情的青春镜像,透露出浓郁的怀旧心态;把文革中的日常生活予以“消费编码”和“温情化”处理,亦是对当下小资情调的同步归趋。这种受到市场与消费主义规约的“文革”叙述的话语形态,导致了对历史深度反思的缺失,亦放逐了对苦难与创伤的追问。
In the context of the marketization and consumptionism, the history of“ CulturalRevolution”makes a worthy literary theme, which meanwhile becomes a type of cultural resources forconsumption and entertainment. The narration of“ Cultural Revolution” in the novels of the new century hasdemonstrated a distinctive form of discourse featuring consumptionism in terms of the narrative style andstrategy. A fixed pattern o“f sex plus revolution” is used to render the queer thoughts on sex during th“e CulturalRevolution” period, thus forming a constructed historical image of that particular period. While retelling thememories of youth during“ Cultural Revolution”, the novelists usually focus on reconstructing a mirror imageof youth filled with freedom, happiness, romance and innocence, showing a strong sense of nostalgia. Itis to some extent a pandering to the current petty bourgeoisie taste and mentality to turn the daily life duringCultural Revolution into a type of recourses for cultural consumption and thus render it a rosy color. This typeof discourse on“ Cultural Revolution”, which is curbed by marketization and consumptionism, leads to alack of profound reflection on the history and misses the chance to explore the sufferings and trauma peopleexperienced at that time
论当代汉族作家“边疆叙事”主题的流变
,
- , 2013,
Abstract: 边疆对汉族作家来说具有“异域文化”的特质,时代历史语境之不同,汉族作家的“边疆叙事”寄寓着不同主题内涵。在1950―60年代的边疆叙事中,多写边疆的革命化历史与现实美景及光明未来,隐含的是民族国家想象的需求与可能; 新时期之初的边疆人性温情故事,它既是书写者历史记忆的复现,又是国家重启现代性工程进行社会动员的需要。从1980年代中后期直至新世纪,边疆叙事主题,则是寻求边疆文化的异质活力以改造国民性和精神救赎。汉族作家“边疆叙事”主题不断变迁,表明汉族现代知识分子对边缘的少数民族文化的复杂态度,亦透递出中国现代性的复杂与暧昧。
Since the frontier and its culture are exotic to them, writers of Han nationality manage to explore the characteristic features of minority ethnic groups, which are different from the majority Han culture. In different historical stages, those writers have different themes when making their “frontier narratives”. During the 1950s and 1960s, they tried to describe the revolutionary history, happy reality and bright future of the frontier areas, the rationale behind which is to meet the requirements of consolidating the image of a nation state. During the period from the late 1970s to the mid-1980s, they tried to delineate the nice and helpful nature of frontier people, which is not only the reconstruction of their personal memories but the requirement of the state to rallying a wide range social support for its modernization drive as well. Since the 1980s, the theme of their frontier narratives, however, is shifted to seeking for the intrinsic heterogeneous vigor included in the frontier culture, which is thought to be able to help reform and strengthen our national character. The evolution of the theme of Han nationality writers’ frontier narratives speaks of their complex attitude toward the frontier people and their cultures and at the same time reflects a complex and equivocal picture of Chinese modernity
新世纪小说中妓女形象谱系与中国现代性问题
,
- , 2015,
Abstract: 新世纪小说中所塑造的妓女形象,成为了一种特殊的喻体,一种感知与体验新世纪中国现实的叙事符码,一种思考中国现代性的媒介。“逼良为娼型”的妓女形象,以妓女苦难叙事揭示城乡二元结构的不平等,追问现代性的冷酷; “赏心乐事型”以妓女自甘堕落的愉悦叙事,批判消费主义时代的精神病像,“知亡国恨型”延续“妓女救国”的故事母题,表明作家重返传统的取向。这三者均表现出反思、质疑与批判现代性的立场。而“从良幻灭型”则对阻滞现代性的传统道德观念表达出愤怒,彰显的是吁求现代性的急切。同为妓女形象,扭结了对现代性不同的价值立场,亦充分说明了中国现代性的特殊性与复杂性。
Prostitute images in novels of the new century are special metaphorical vehicles and narrative codes offering us insights into the social reality of China in the new century and an approach to the issue of China’s modernity. These prostitutes mainly fall into four categories. Some are forced to engage in prostitution for utter misery, revealing the inequality of urban-rural dual structure and the cruelty of modernity. Some choose to be prostitutes on their initiative, through whose experiences the authors criticize the typical ill mentality in the age of consumerism. Some play an active role in the anti-Japanese war, in line with the motif of prostitutes saving the nation, indicating the authors’ return to traditional values. Some are excluded from the rural society for their past as a prostitute thus failing to return to normal life. The first three types show the authors’ reflections on and criticisms of modernity, while the last one manifests their calling for modernity and rage against the outdated traditional values. These prostitute images, endowed with different values in modernity, reveal the particularity and complexity of China’s modernity
对AHP层次总排序方法的扩展

系统工程理论与实践 , 1992,
Abstract: 层次分析法是将定性问题进行定量分析的一种简单而实用的决策方法。基本过程是:对所分析的问题建立层次模型,然后将一个层次的各因素相对于上一层次的各准则(或目标)进行两两比较判断,构造判断矩阵,通过对判断矩阵的计算,进行层次单排序和一致性检验,最后进行层次总排序,得到各因素相对于决策目标的优选序列,作为决策的依据。 层次总排序是层次分析法中的一个重要环节,它得出了问题的最后结果,而最后结果是否合理,直接影响到决策的效果。根据现行的决策理论,不同的问题应当采用适当的决策方法,以使结果可靠,而

Abstract:
针对欺骗干扰信号常在时域、频域和空域与真实信号重叠,导致识别欺骗干扰难度较大的问题,本文假定真实发射机与欺骗干扰机射频前端器件除数模转换器(DAC)外均工作于理想状态,提出了一种基于DAC建模的欺骗干扰识别方法。首先,利用积分非线性(INL)和差分非线性(DNL)对DAC的非线性进行统计建模,提取特征向量;其次,基于似然比检测和欧氏距离法实现欺骗干扰识别;最后,通过仿真实验验证了方法的有效性。
Since real signals and spoofing signals are overlapped in time domain, frequency domain and time-frequency domain, it is not easy to distinguish them. In this paper, a new identification method based on the model of digital-to-analog converter (DAC) is proposed on a condition that the devices of transmitter and jammer are in desired state except the DAC. Firstly, the DAC is modeled with the integral non-linear (INL) and differential non-linear (DNL) to extract the parameter vector; secondly, the spoofing signals are identified by using a LRT detector and a na?ve method; lastly, the effectiveness of the proposed method is verified via simulation.
种子异型性及其生态意义的研究进展

植物生态学报 植物生态学报 , 2010, DOI: 10.3773/j.issn.1005-264x.2010.05.012
Abstract: ?种子异型性是指同一植株产生不同形状或行为种子的现象。根据异型种子在植株上的生长位置,种子异型性可划分为地上下结实性和地上种子异型性两类。此现象已在26科129属292种被子植物中报道。异型性种子植物主要分布于干旱半干旱区、荒漠和盐渍土地区等干扰强烈的环境,在菊科和藜科中最为常见,主要出现在一年生植物中。种子异型性在避免密集负效应、减弱同胞子代间的竞争、采取两头下注策略以适应时空异质性环境等方面具有重要的进化生态意义。该文系统总结了国内外种子异型性的研究工作,主要内容包括:1)种子异型性的概念、类型和种类,2)具有异型种子植物的生境和生活型,3)异型种子的生态学特性,4)种子异型性的理论模型,5)种子异型性的生态意义。在综述文献的基础上,对今后的研究进行了展望。针对国内外的研究现状,提出两点建议:1)系统调查具有种子异型性现象的植物种类,摸清其生物学特性;2)确定研究种子异型性现象的模式植物,从生态学、生理学和分子生物学等学科角度来研究种子异型性的个体发育机制及分子调控机理。
种子异型植物异子蓬的生殖分配和结实格局
,, 黄振英
植物生态学报 植物生态学报 , 2012, DOI: 10.3724/SP.J.1258.2012.00948
Abstract: ?选择能产生异型果实和种子的一年生盐生植物异子蓬(Suaedaaralocaspica)为研究对象,研究其生殖分配和结实格局。结果表明,异子蓬具有较高的生殖分配和规律性的“谨慎型”结实格局。异子蓬的生殖分配高达56%。在资源充裕时,该植物对扁圆形棕色种子(采取机会主义的萌发策略)的投资多于双凸镜形黑色种子(采取谨慎的萌发策略)的投资。异子蓬的花序类型为二歧聚伞花序,单个果序含果实(种子)的数目为1–15个,最多可分为4级。果序内果实的分布具有一定的规律:第一级1个果实,第二级2个,第三级4个,第四级8个。异子蓬优先将资源供给黑色种子的果实,利用不同类型种子的发育顺序,首先保证黑色种子的产出。具有较高的生殖分配和采取“谨慎”的生殖策略是异子蓬与其所处盐漠环境长期适应的结果。

恒温下煤粉/生物质混燃特性及NO释放规律
王春波,王金星,,
煤炭学报 , 2013,
Abstract: 利用自制的恒温热重测量实验台研究生物质掺混比、煤种、生物质种类及温度等因素对煤粉/生物质混燃特性及NO释放规律的影响。结果表明:生物质掺混比增大后,燃烬时间提前,NO析出率降低;生物质掺烧后对难燃煤种的燃烧特性影响较大,对含灰量高的煤种降低NO排放作用较小。生物质种类在反应初期对试样的燃烧特性曲线影响不大,但随着燃烧的进行,含灰量高的生物质对混燃特性的改善作用逐渐减弱。掺混高含氮量生物质,试样的NO析出率下降较大,但对于含氮量相差不多的生物质,含灰量越高,NO析出率下降越明显。温度在反应初期对燃烧特性的影响不明显,但对反应后期的燃烧特性影响显著。在所选的温度区间内,温度越高,NO析出率越高。

Abstract: 用IR75589-31S、IR60、IR70和90个籼粳成分不同的株系进行不完全双列杂交,以获得的270个杂交组合为材料,对杂交稻米外观品质遗传及性状间的相关进行了研究。结果表明:垩白度、粒长、粒宽及粒长宽比间的相关系数均达极显著水平,粒长、粒长宽比与垩白度呈显著负相关,粒宽与垩白度显著正相关;粒长、粒宽和粒长宽比对垩白度的直接通径系数分别为-1.9409、2.1738和2.7805。杂交稻外观品质性状主要受遗传控制且遗传效应均以加性效应为主。粒长、粒宽和粒长宽比以种子加性效应为主,母体效应也起到一定的作用,垩白度主要受到种子效应和母体效应控制,同时还受到细胞质的影响。粒长、粒宽和粒长宽比三性状的狭义遗传率都在80%以上,其中以粒宽为最高,达89.90%,垩白度的遗传率相对较低,为72.94%。
