Results 9 cases of retinoblastoma showed the high-density tumor,calcific plaque as well as extraglobal extensions.6 cases of choroidal melania showed the retrobulbar tumor with enhancement.2 cases of coats disease showed the density in the crystalline lens of the eyeball diffuse enhanced and CT volue was from 60 to 88 HU.

结果 视网膜母细胞瘤9例，表现为眼球内高密度肿块、钙斑及球外侵犯。脉络膜黑色素瘤6例，表现为眼球后部肿块，多明显强化。Coat's病2例，表现为眼球玻璃体内密度弥漫性增高，CT值60～88HU。

The small intestinal diseases (28.9, 13/45) mainly comprise inflammatory diseases, Meckel diverticulum and hemangioma. The dramatic presentation of bleeding is hematochezia (93.3%, 42/45), the other 3 cases of the diseases located in small intestine presented as melena. None of patients accompanied by hematemesis.

在出血表现方面，除3例小肠病变（其中血管瘤1例，美克尔憩室2例）只表现为大量黑便外，其它不论是发生于大肠还是发生于小肠的病变（共42例，占93.3%），均以不同程度的排血便作为主要出血表现，没有伴发呕血或呕吐咖啡样胃内容物。

By the field survey which lasting a period of 3 grown seasons and by the means of remote sense and geographic information system, we ascertain the present vegetation pattern of Hunshan-Dake sand land, find out vegetation distribution principles on the different scales in the same time . From west to east, with the increasing of dry degree, the type of plant community changed form the xeric to the mesic. The vegetation of Sand land shows the characteristic of the zonal vegetation, but dont consistent with the traditional diversification principle. The vegetation of the middle part displays a high differential characteristic, which compresses the longitudinal zonation at a certain extent. So we can say that sand land vegetation is semi-zonal.

通过对浑善达克沙地历时三个生长季的地面考察并应用遥感及地理信息系统等手段，确定了浑善达克沙地植被分布现状及浑善达克沙地植被在不同尺度下的分异规律：由西向东，沙地植被随着干燥度的降低，由旱生群落为主的区段递变为以中生群落为主的区段，表现出具有一定的地带性植被特征，但与传统的地带性植被的递变规律不相一致，沙地中段的植被表现出了高度的特异性，在一定程度上压缩了植被的经向地带性，表现出沙地特有的地带性分布规律，所以认为沙地植被是一种半地带性植被。

Objective:To analyze the MR findings of neurogenic tumors in spinal canal and compare with meningioma.

目的 ：通过高场强MR对椎管内神经源性肿瘤的表现特征进行分析，并与脊膜瘤的MR表现进行对比研究，以期总结本病的MR表现特征及与脊膜瘤鉴别诊断要点。

Ki-67 and Pgp expressions were measured by immunohistochemical analyses on multiple nonconsecutive sections from surgery or biopsy specimens of breast cancers.

结果：11位具有Ki-67表现乳癌病患，其肿瘤－背景比值明显高於13位无Ki-67表现者(4.26±0.41对2.25±0.33，P＜0.05)，然而8位具有P-醣蛋白表现及16位无P-醣蛋白表现，其肿瘤－背景比值则无明显差异(3.52±0.40对3.42±0.45，P＞0.05)。

Swyer-James syndrome is considered to be a post-infectious form of bronchiolitis obliterans, pathologically defined by the presence of submucosal and peribronchiolar fibrosis with destruction and obliterative scarring of the small airways.

Swyer-James综合征被认为是闭塞性细支气管炎感染后形成的，病理表现为出现黏膜下及支气管周围纤维化并有小气道破坏和疤痕组织，SJS是一类有不同临床表现的综合征，这些表现主要与囊状支气管扩张是否出现有关。

With vertical-section analysis, in the later of experiment, naked terra and wheat land make content of soluble salt high in 0～20cm,and decreasing with deepening of soil-layer; the content value of planting two-year-old Onobrychis viciaefolia 、one-year-old Onobrychis viciaefolia 、interplanting and sequential cropping in the every soil-layer is equal; in harvest, only planting wheat and interplanting display content of soluble salt is high in middle-layer (20～60cm) and low in surface and down layers(0～20cm,60～80cm).

土壤垂直剖面分析，试验末期裸地的土壤盐分表现为0～20cm 土层高，随土层深入含量逐渐降低；二年生红豆草、一年生红豆草、套种和复种处理的土壤盐分均表现出各层含量近似相等的特征；小麦收获期，单作小麦和小麦套种地各土层的可溶性盐含量均表现为中层(20～60cm)高、上下层(0～20cm 和60～80cm)低的特征。

In this paper, 1554 strains of bacteria were isolated from the soybean rhizophere in the different continuous systems. Those biocontrol bacteria were screened in vitro and in vivo. 6 strains of them had the better control efficacy. They exhibited the different antagonism to the pathogens of soybean root in vitro. The strains 18BR2-2 and 18BR9-1 showed a wide range of antagonism against Fusarium oxysporum, F. avenaoeum, F. solani and Rhizoctonia solani in vitro. The 6 strains exhibited different control efficacy to soybean root rot in greenhouse and in field. In greenhouse, they could decrease the degree of soybean disease significantly, and the control efficacy of 18BR2-2 was the best and can reach 45.90%. In theory, soybean treated by 18BR2-2 may postpone the days of outbreaking of disease for 6 days. The strain 18BR2-2 also promoted the growth of soybean seedling and, raising the soybean height for 11.24%, increasing dry weight for 40.91% and fresh weight for 35.27%.

本研究从长期连作田种植的大豆及其根际土壤中分离细菌1554株，采用平板测试、温室盆栽及田间试验等方法，筛选了对大豆根腐病菌(主要是尖孢镰孢菌Fusarium oxysporum)有很好作用效果的生防细菌6株，在离体的条件下均表现出不同程度的拮抗作用，其中生防细菌18BR2-2和18BR9-1表现出很广的杀菌谱，对大豆根腐病菌尖孢镰孢菌(F.oxysporum)、燕麦镰孢菌(F.avenaoeum)、茄腐镰孢菌和立枯丝核菌都有很好的离体拮抗作用，并且这6株生防细菌在盆栽和田间的情况下均表现出对大豆根腐病一定的防治效果。

When Griffis eagerly anticipates the narrative montage after Hollywood the mainstream, the Chaplin accident in is also emphasizing the single lens' expressive force, although he has also utilized some similar "Modern Time" begins the sheep and worker's two lens such performance montage technique, but more time he in faithful with panoram lens performance movement experience time,"Modern Time" mid summer Luo river the scene which sings in the dining room, the fixed positive panoram angle of view, the similar play's onlooking way, the audience can only see Xia the Luo one-man show, can obtain in merely the dining room from lens' laughter people's response,This is certainly for the more comprehensive clear performance its comedy movement and the scene, but actually unavoidably has "adheres to traitors" suspicion of the stage show.

当格里菲斯在好莱坞引领起叙事蒙太奇的主流之后，卓别林意外的还在强调著单个镜头的表现力，虽然他也运用了一些类似《摩登时代》开头绵羊和工人的两个镜头那样的表现蒙太奇手法，但更多的时候他还是在忠实的用全景镜头表现动作的经验时间，《摩登时代》中夏洛尔在餐厅中唱歌的场面，固定的正面全景视角，类似戏剧的观看方式，观众只能看到夏尔洛的独角戏，仅仅能从镜头之外的笑声中得到餐厅里人们的反应，这当然是为了更全面清楚的表现其喜剧动作和场景，但却难免有&附逆&舞台表演之嫌。

It typically presents as a pedunculated or sessile mass, slightly hypo- or isointense to cortex on T1 and generally slightly bright on T2, without contrast enhancement and stable over time.

典型表现为有蒂或无蒂的肿块，T1序列上表现为稍低或等信号，T2为稍高信号，无强化，MRS表现为低NAA，正常到轻度升高的胆碱峰和高肌醇。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
