叶赫那拉氏族谱从一个重要的实证角度浓缩了满族的集体历史记忆,与其他满族家族记忆构成了满族族群自我认同的文化基础,运用其中的宗教神话记忆、满族共同体形成的记忆、民族迁徙历史记忆、满汉文化交融的记忆以及道德生活记忆是当前满族历史文化研究的重要方式之一,即新史学、社会学、文化人类学甚至伦理学等多学科交叉研究的范式,它对今天研究构建多元一体民族新文化体系的意义重大。
Yehenala genealogy is a concentration of the Manchu collective historical memory from an empir?ical view. It constitutes the cultural basis of the Manchu ethnic identity together with other Manchu clan memories. One important way of current research of Manchu history and culture is to study the religious myth memory, the for?mation of the Manchu community memory, the memory of ethnic migration history, the memory of cultural integra?tion with Han and moral life memory. That is a multidisciplinary research paradigm including new historiography, sociology, cultural anthropology and ethics, which is of great significance to the study of construction new national cultural system with diversity in unity.

赫钦斯的《美国高等教育》一书是对20世纪上半叶美国高等教育现状的一种批判,今天细细读来,依旧发人深省,似乎当时美国高等教育中出现的问题对应了现阶段我国高等教育出现的弊端,让笔者不禁对我国高等教育产生了反思。
The book "American Higher Educaiton" by Hutchins is a criticism of the status quo of American higher education in the first half of the 20th century. Reading it carefully, the writer is profoundly inspired. It seems that the problems of American higher education at that time are equivalent to those of Chinese higher education at the present stage, which arouses the writer''s reflections on Chinese higher education.

周期信号频谱分析在信号与系统这一学科中占有极其重要的地位。满足狄里赫利条件的非正弦周期函数可以展开为傅里叶级数,基于此事实,以傅里叶变化作为信号分析的理论基础,可以将非正弦周期信号视为一个直流分量与若干个不同频率的正弦分量之和。通过对频谱宽带的理解,研究了矩形脉冲波形的变化对其频谱的影响。
The periodic signal spectrum analysis plays an extremely important role in this discipline in signals and systems. Satisfy the conditions of non-sinusoidal periodic Dirichlet functions can be expanded into Fourier series, based on this fact, the theoretical basis of the change as a signal to Fourier analysis can be considered as a non-sinusoidal periodic signals with several DC component sinusoidal components of different frequencies. By understanding the broadband spectrum, the effect of the rectangular pulse waveform changes its spectrum.

风场风况是影响风力机气动和结构特性的直接因素,进而影响功率输出、稳定性和控制策略。在三维风场建模的基础上,对5种不同风况下的风速及相干湍流风的时域变化进行了模拟。结合气动计算结果对各风况下的叶尖挥舞和摆振位移,叶根挥舞、摆振、变浆力矩进行了动力学响应仿真,得到其各自的动态响应。控制策略采用变桨、变风速控制,极限风况下采用定时顺桨控制。结果发现克赫波更适合极限风况的仿真,并且通过添加相干湍流到基础湍流上能模拟拟序结构。同时,研究表明相较于参考风速为额定风速,在切出风速下,叶尖位移同时体现为挥舞和摆振,且变化频率、剧烈程度都增加;叶根载荷中挥舞弯矩均值较小,但在短时间内波动跨度大,是风力机叶片产生疲劳的主要载荷。
ABSTRACT:The wind directly decides the aerodynamic and structural characteristics of wind turbine, which affect the power output, the stability and control strategy. On the basis of modeling full field wind, this paper simulated five different wind fields with different speed or turbulence intensity. Combined with the aerodynamic results, it simulated the dynamic response of the out-of-plane, in-plane tip deflections; out-of-plane, in-plane, pitching moments at the blade root. Variable speed & pitch were used as the wind turbine control strategy at the rated wind speed events. Under the wind of extreme turbulence, the control strategy was normal pitch-to-feather. The results show that the Kelvin-Helmholtz billow is more suitable for turbulence wind simulation. It can simulate coherent structure by adding a coherent turbulence wind on the background wind. At the same time, the study shows that the reference wind speed is the rated speed, the cut-out wind speed simulations have

采用化学连续提取法研究了赫章铅锌矿冶炼区农田土壤以及马铃薯根、茎、叶、果实(块茎)中Cd含量及其化学形态分布特征,以揭示该污染区Cd在土壤与植物体内的迁移转化特征。结果表明,农田土壤Cd含量介于2.53~22.30 mg/kg,且以可交换态和铁锰氧化物结合态为主,土壤p H值与土壤可交换态Cd含量呈显著负相关,与铁锰氧化物结合态Cd含量呈显著正相关。马铃薯各器官Cd含量总体表现为根、叶、茎大于果实,且主要以氯化钠提取态和去离子水提取态为主;马铃薯除果实外,根、茎、叶中Cd含量几乎全部超出国家食品安全限值,存在较高的生态风险。土壤 p H值与马铃薯根、茎中Cd含量呈显著负相关;土壤有机质含量与马铃薯叶中Cd含量呈极显著正相关;马铃薯根中Cd含量与茎中Cd含量呈显著正相关。总之,土壤p H值是影响植物吸收Cd的重要因素,其主要通过影响Cd在土壤中的形态分布来影响Cd向马铃薯体内的迁移。控制土壤p H值可有效降低土壤中Cd向植物迁移的能力和农作物中的Cd含量,保障当地农作物食品质量安全。

GECROS 是荷兰瓦赫宁根农业大学近些年开发的机理性更强、算法更简要的作物生长模型。本文利用黄淮海地区夏玉米试验数据进行GECROS模型的适应性评价,为模型进一步开展区域应用提供依据。结果表明, GECROS基本能够反映黄淮海地区夏玉米的发育进程。模型模拟夏玉米抽雄期的绝对偏差在6.0 d以内,平均为2.1 d;模拟成熟期的绝对偏差在8.0 d以内,平均为3.4 d。GECROS描述夏玉米干物质积累和叶面积扩展过程的准确度较高。模拟雌穗总重的归一化均方根误差在7.8%~33.8%之间,平均为18.6%;模拟植株地上总重的归一化均方根误差在11.2%~32.6%之间,平均为20.7%;模拟LAI的绝对偏差在0.28~0.55之间,平均为0.41,模拟籽粒产量的绝对偏差在20.3~229.0 g m–2之间,平均为80.9 g m–2。利用GECROS模型相对评价作物生长状况或环境影响基本可行。但GECROS 模拟夏玉米发育进程仍存在低值偏高、高值偏低的现象;在土壤水分胁迫较重时,描述的生物量积累过程有偏低情况;描述LAI扩展的总体效果差于生物量累积的效果。GECROS仍需进一步完善。
The evaluation of crop model is a key process for its application. GECROS model had been developed by Wageningen in recent years. GECROS uses stronger mechanism and more concise algorithms to summarize the current knowledge of individ-ual physiological processes and their interactions and feedback mechanisms. To provide a foundation for the future localization and regional application of GECROS model, in this study, the field observations of summer maize from several agrometeorologi-cal stations in Yellow-Huaihe-Haihe Rivers were used to conduct the adaptability evaluation of GECROS model. The results showed that GECROS model could basically reflect the growing process of summer maize in Yellow-Huaihe-Haihe Rivers. The absolute deviations at the period from emergence to tasseling simulated by GECROS were less than 6.0 d, with an average of 2.1 d. The absolute deviations at the period from tasseling to mature were less than 8.0 d, with an average of 3.4 d. The dry matter accum
