目的:研究汉语听写困难儿童在处理一般图形时视觉的整体和部分加工特点.方法:从三、四、五年级的儿童中,筛选出听写困难儿童22名,同时选择年龄、智力水平相当的对照组儿童24名.实验l采用形状变化探测任务,以由小图形构成的大图形为视觉材料(所有大、小图形均为三角形、圆形、方形或菱形四种形状),要求被试在大图形发生整体变化、部分变化两种条件下作出判断,记录正确率和反应时;实验2采用整体部分同时加工任务,以与实验1类似的视觉材料作为刺激(区别在于所有大图形由与之形状不同的一种小图形构成),要求被试判断大、小图形中是否包含圆形和三角形,记录被试在整体判断和部分判断两种条件下的正确率和反应时.结果:在实验l中,整体变化条件下,听写困难组的正确率和反应时均落后于对照组儿童,部分变化条件下两组被试的差异不具有统计学意义;在实验2中,整体判断条件下,听写困难组的正确率和反应时显著低于对照组,部分判断条件下,两组被试的差异无统计学意义.结论:听写困难儿童在一般视觉材料的处理中表现出整体加工落后、部分加工良好的特点,这与听写困难儿童在汉字学习过程中倾向于一笔一划地书写、无法写出完整字形的表现相符合.

The reduction in average global ozone layer may cause the enhance of solar ultradiation adiation(UV-B)that reach to the ground surface.We selected the cash crops of winter wheat which grown in northern China to studied the influence of UV-B radiation on plants.Using the method of two-dimensional electrophoresis to analysis changes of the protein in wheat leaves by UV-B radiation.The results showed that wheat leaf protein of the first four days,eight days changes significantly.The two dimensional gel electrophoresis revealed 15 differentially expressed polypeptides,3 of which were successful identified by mass spectrometry,including Copper/Zinc Superoxide dismutase,Calmodulin,Rubisco large subunit binding protein subunit alpha.The results showed that enhanced UV-B radiation can be regulating the gene encoding protein of wheat leaf to adjust plant growth.

Shan 23section of Neopaleozoic Shansi group is one of the principal natural gas producing formation in the northern Sulige gas field of eastern area.Braided fluvial deposition mainly develop in the reservoir,among which batture microfacies are the most favorable sedimentary facies zone.Through data analysis of cast slice, reservoir properties, mercury penetration and scanning electron microscope,the results show that quartzy sandstone predominates in the lithology which has characteristics of high maturity minerals and low textural maturity lithology, and pore types are mainly interparticle dissolution pore and Inter-crystalline pore. The overall physical property is poor and belongs to low porosity and permeability reservoir.Compacting action and cementation are the key factors to form low porosity and permeability reservoir in the area while chemical erosion has positive effect on improving the physical property of reservoirs.From above analysis the reservoirs in the study area can be divided into 4 kinds. Reservoirs grow relatively well in Type II formation.

A double-level design is presented in this paper in order to achieve bus signal priority under arterial signal progression,the upper level is progress control,in which the largest green wave band method is adopted to optimize the main intersection of public cycle,green ratio and phase difference based on the data of car flow detector and the lower level is bus priority control in which green extension and red truncation are adopted to achieve bus signal priority under the condition of signal coordination.According to the algorithm,bus priority control process is established using the microscopic simulation software transmodeler simulates validation.The simulation results show that the control of bus priority under coordinated control algorithm can reduce bus delay and the average delay per line although increase the trunk delay.

苏里格气田东区北端上古生界山西组山23段是天然气的主力产层之一,储层段主要发育辫状河沉积,心滩微相为最有利的沉积相带.通过铸体薄片、储层物性、压汞及扫描电镜等资料对储层特征进行分析,研究结果表明:储层岩石类型以石英砂岩为主,有矿物成熟度高而结构成熟度低的岩石学特点,孔隙类型以粒间溶孔和晶间孔为主,总体物性较差,属于典型的低孔低渗储层.研究区较强的压实作用、胶结作用是形成低孔低渗的主要因素,溶蚀作用改善了储层物性;研究区山23段分为4类,其中以Ⅱ类储层较发育.

Sangonghe of Mobei oilfield is the the main purpose of the interval.Though the data from cast thin section,reservoir properties,and logging data analysed reservoir characteristics.The results show that sandstone reservoir are mainly ranging from lithic sandstone and fine grain-medium-grained lithic sandstone, the cuttings is given priority to with tuff.Research zone sandstone- in the overall property belongs to low porosity, low- low permeability reservoir.Reservoir throat are the typical features of big throat development, and different penetration levels of throat radius size and distribution of big differences.And the inner layers of the macroscopic heterogeneity, interlayer heterogeneity and plane heterogeneity study found these aspects,there are three main categories in mezzanine of Sangonghe delta reservoir: intercalation,argillaceous interlayer,dense intercalation.The research areas develop much sandwich,and heterogeneity is serious.Plane distribution of physical properties also reflects the long strip of underwater distributary channel deposit,and underwater distributary channel property to be significantly better than simply phase in the channel between the edge and the deposition,overall reservoir physical parameters of plane heterogeneity is stronger.

This study,by testing 28 children with Chinese-language dyslexia and 28 normal children with three kinds of pictures,under different levels of difficulty in language information processing,aims to probe into the effect of orthographical and phonological coding difficulty on the scores in the grapheme-sound connection from children with Chinese-language dyslexia.The results show the following:(1) The children with Chinese-language dyslexia show a lower rate of accuracy of the grapheme-sound connection than the normal children under a low level of orthographical and phonological coding difficulty,as indicates that the children with Chinese-language dyslexia lag behind the normal children in the grapheme-sound connection.(2) When the orthographical coding becomes more difficult,the children with Chinese-language dyslexia show no significant change in their scores in the grapheme-sound connection;but when the phonological coding becomes more difficult,they show a significant decline in their scores in the grapheme-sound connection,which suggests that orthographical coding difficulty has no effect on their grapheme-sound connection,whereas the phonological coding causes the change in the scores in their grapheme-sound connection.

Based on former researches of teacher professional identity and characteristics of tuition-free normal college students,this research proposed a new theoretical model to measure teacher professional identity of tuition-free normal college students.284 and 168 tuition-free normal college students from Beijing Normal University were investigated to explore and verify the structure of the model separately.Survey data of 714 tuition-free normal college students is used to analyze characters of their teacher professional identity.The results showed:(1) the teacher professional identity of tuition-free normal college students consisted of three sub-dimensions which were intrinsic value identity,extrinsic value identity and volitional behavior identity;(2) the level of the teacher professional identity is little above average level but still has space for promotion and in the three sub-dimensions,it declined successively.Besides,there were demographic differences in the three sub-dimensions,such as original area,gender,and grade level.At last,the researchers discussed the results above and put forward relevant suggestions.

Lead poisoning has greater effect on human body,especially growth and development of children.Lead removing drugs have obvious effect,but it is only used for emergency.In this paper,mechanism of lead removing with natural foods was discussed,such as coordination,adsorption,precipitation,antagonism,antioxidant role and so on.Natural lead removing functional foods include materials containing large amounts of protein and amino acids,pectin,trace elements,polyphenols,functional polysaccharides.The paper can provide a scientific basis for preventing lead accumulation and lead removing.
