怀山药与同属植物甾体成分差异性比较研究
刘绣华a,b白,a
河南大学学报(自然科学版) , 2012,
Abstract: 采用HPLC、GC-MS等技术手段,对怀山药块茎甾体成分进行了分析.结果在怀山药中未检测到薯蓣皂苷及其苷元,而检测到大量的植物甾醇;同时对薯蓣属植物进化次序与甾体成分差异之间的关系进行了分析,指出甾体皂苷是一类原始成分,植物甾醇是一类进步成分,其差异性主要由参与生物合成的关键酶的差异所致.研究结果为山药的开发利用及薯蓣属植物的分类提供了参考.

Abstract:
方言地理学在中国长期没有得到重视,而全国性的汉语方言地图集也迟至2008年才首次出版。本文以《汉语方言地图集》(LACD)词汇卷007图(冰雹)的研究为例,具体阐述进行汉语词汇地理学研究的一般程序(描写性地图的绘制;解释性地图的绘制;解释性地图的进一步解释),并归纳出4种主要的研究方法(历史比较法;文献考证法;空间分析法;外部解释法)。本文对“冰雹”的个案研究在程序和方法上都具有典型性,可作为开展基于LACD的汉语词汇地理学研究的样例。
In China, for many years people didn’t attach importance to Dialect Geography. Only until the year 2008, was the first national Chinese dialect atlas published. This paper takes the Chinese word bingbao “hail” as an example, which is extracted from Map 007, in the vocabulary volume of Linguistic Atlas of Chi-nese Dialects (LACD), to expound the general procedures of the study on Chinese Word Geography. The procedures are the following: first, drawing a descriptive map; second, drawing interpretive maps; last, fur-ther explanations on the interpretive maps. Besides the procedures, the author also sums up four main re-search methods: historical comparative method; classic literature research method; space analysis method and external interpretation method. Because of its typicalness both in procedures and methods on the case study of the Chinese word bingbao “hail”, this paper can be used as a good example for the further studies of Chi-nese Word Geography based on LACD.

Abstract: 本文详细记述并分析了一例,原发不孕症患者,针灸合并中药辨证论治并治愈的全过程,以及治疗心得,启示及讨论点。病例的特殊性在于,患者属先天性卵巢发育不全重症,FSH高达30 mlU/mIVF 6次失败,合并免疫系统疾病强直性脊柱炎及多汗症。治疗4个月自然怀孕,产有一子,隔年自然怀孕又产一女。治疗全程有法国IVF专家全程B超监控
The writer has particularly detailedly recorded and analysed the treatment process of a primary infertility cured by combining therapy of Acupuncture and Chinese Herbal Medicine based on TCM syndrome differentiation, the gains in depth of comprehension, revelations and some issues of discussion. The specialities of the case are that the patient has Congenital Agenesis of Ovaries, FSH 30 mlU/ml, 6 times IVF failures history, Ankylosing Spondylitis, and hyperhidrosis. She was pregnant after 4 months treatment, and then delivered a baby boy, followed by a baby girl after one year by natural pregnancy. The whole course of the treatment is under the ultrasound scan monitor by a French IVF specialist.
灞河流域气候变化及其对径流的影响研究
Study on Impacts of Climate Changes on Bahe River Runoff
 [PDF]

Journal of Water Resources Research (JWRR) , 2013, DOI: 10.12677/JWRR.2013.26060
Abstract: 根据1961~2010年的灞河流域内的逐月水文气象数据,采用Mann-Kendall法对水文气象要素进行变化趋势分析,采用双累积曲线和复回归模型进行径流量的气候变化响应研究。结果表明:流域内年径流量显著减少,年平均气温和年降水量均无显著的变化趋势,仅仅表现为气温略升高、降水稍减少;气温变化和降水变化对径流量的影响各自存在三个突变点,突变点前后径流量增加或减少的变化明显,由回归分析可知,气温升高、降水减少是径流量减少的主要原因。
Based on hydrological data for Bahe River from time series of 1961 to 2010, the trend of hydro- logical and meteorological elements was analyzed by using the Mann-Kendall method. The runoff response to climate change is researched with Double mass curves and multiple regression models. The results showed that: the runoff significantly reduced while the annual mean temperature and annual precipitation have no significant trends, with only slightly elevated temperature and precipitation decreasing slightly; by the regres- sion analysis, runoff reduction is mainly due to rising temperatures and reduced precipitation.
说“冰雹”
On Chinese Word Bingbao “Hail”

Abstract:
汉语指称雹子的“冰雹”一词集中分布在长江中下游一带,其连续分布区是一个略呈马蜂形的东北西南向宽带。这种特定的地理分布格局跟“冰雹”一词的形成有关。在马蜂形宽带的南边,是“雹”或“雹子”一类说法的连续分布区,北边则是“冷子”一类说法的连续分布区。“冷子”是“雹()→冰蛋子冷蛋子冷子”这一词汇替换演变的结果。因此“冰雹”一词是历史上中原地区的“冰蛋子”和它南边的“雹()”两种词形互相接触所产生的混合词形,这就解释了为何会在长江中下游出现东北西南向的“冰雹”带状分布区。
The continuous distribution area of the Chinese word for “hail” bingbao, located in the middle and lower reaches of theYangtze River, is a slightly wasp-shaped broadband running from northeast to southwest. This particular geographical distribution pattern is associated with the formation of the word bingbao. Bao or baozi, the word for “hail” is widely spoken in the south of the broadband, while the word for “hail” lengzi is a common word in the north of the broadband. Lengzi is a result of lexical changes “bao/baozibingdanzilengdanzilengzi”. Therefore, the word bingbao was actually the contamination of

Abstract:
使用注意瞬脱研究范式,变化其中T2相对T1的颜色特征或类别一致性,探讨刺激性质变化对注意瞬脱的影响,结果发现,T2相对T1的颜色改变可以减弱注意瞬脱效应,T2相对T1的类别变化可以消除注意瞬脱效应。注意瞬脱是有限资源的分配方式造成,但是注意瞬脱的产生受刺激类别关系的影响。
This study investigated the effects on Attentional Blink (AB) when the category relationships of two targets in a rapid serial visual presentation stream were consistent or not. In experiment 1, accuracy for the second target (T2) increased when its color was changed, but there was still a sig-nificant Attentional Blink effect. In experiment 2, the results for T2 showed that there was no sig-nificant Attentional Blink effect when T1 and T2 belong to the different categories. These findings support the hypothesis that AB is due to an allocation of limited attentional resources. But whether the AB effects come into being or not is deteminated by the relationships of category between T1 and T2.
脑小血管病相关认知功能障碍的影像学评估研究进展

 [PDF]

Abstract:
脑小血管病主要是指小动脉及微动脉病变引起的缺血或出血性改变,它是引起血管性认知功能障碍主要原因。影像学上主要表现为脑白质高信号,腔隙性脑梗死,脑微出血及血管周围间隙扩大,这四种类型分别可以使用多种评价方法进行定量和半定量评估,对于解释相应的认知功能减退提供了客观依据。
Cerebral small vessel disease (CSVD) is the most common vascular cause of cognitive impairment, which refers to a group of ischemic and hemorrhagic changes that mainly affect the small arteries and arterioles. Features seen on neuroimaging include white matter hyperintensities, lacunar infarction, cerebral microbleed and enlarged perivascular space, which can be assessed by both quantitative analysis and semi-quantitative analysis, and this can provide evidence for the explanation of cognitive impairment.

Abstract: 为保证施工现场条件的干燥性,必须采取措施降低地下水水位,但是降水后会引起土体的固结沉降,对地面早已存在的建筑物构成潜在的威胁.工程降水施工诱发地基沉降是一个三维空间流固耦合问题,借助三维有限差分数值模拟软件FLAC3D建立地层降水过程中渗流场与应力场耦合模型,以金普线地铁隧道8标降水工程为例进行数值模拟,探究土体在饱和状态下改变地层渗透系数达到渗流稳定时的沉降和地下水分布特征.
第十一届国际心理学注意和行为会议简介

心理科学进展 , 1985,
Abstract: 作为中国观察员我七月初出席了第十一届国际心理学注意和行为(Attention and performance)会议。会议在美国西海岸北部城市Eugene市的Oregon大学举行。到会的七十多位心理学家来自世界各地,他们中的三十多位作了大会发言,为期一周的会议内容很广泛,不仅包括注意而且涉及行动控制,语言,大脑两半球的联系等。会上会下心理学界的同行们围绕着注意到行为这一认知过程的重要阶段的许多问题,都广泛深入地进行了学术交流。我注意到了一些很有希望的心理学家并没有作大会发言(象A.Treisman,S.Sterberg)。会议主席团的一个成员告诉我,因为发言的机会有限,他们规定把一比例的发言机会留给年轻人及第一次参加会议的人。然而每一个发言都是经推荐,初稿审批,邀
