DESIGN: Cross-sectional study based on patients with dementia praecox.

设计：以精神分裂症患者为观察对象的横断面研究。

Results:In this series,12 were located in the basal ganglia,2 in the thalamus and 3 in both regions.The tumors rarely had associated edema.4 patients demonstrated cortical atrophy ipilaterally.Most of the turmors′enhancerment was hetergeneous.In axial section,the diametre ranged from 30 mm to 65 mm,46.43 mm on an average.

结果：17例中，12例位于基底节区，2例位于丘脑，3例同时累及丘脑和基底节区，横断面上最大径65mm，最小径30mm，平均46.43mm，16例增强不均匀，11例无瘤旁水肿，5例水肿较轻，4例出现同侧大脑半球萎缩。

Methods: This was a cross-sectional single-center study. Between April 2008 and December 2008, consecutive dyspeptic outpatients were evaluated with standard Rome III diagnostic questionnaire.

研究目的：比较功能性消化不良不同次分类的病人，其精神病理压力与人格特质是否不同研究方法：这是单一中心的横断面研究。

According to the results, the contour of cross section is related to the relative radius of punch; the maximum equivalent plastic strain is an increasing function of it and the ellipticity is a decreasing function of it.

研究结果表明，成形件的横断面轮廓形状与相对凸模半径有关；最大塑性等效应变是相对凸模半径的递增函数；椭圆度随相对凸模半径的增加而减小。基於研究结果，本文给出了相对凸模半径的设计原则。

OBJECTIVE To study the benefit of prevalence survey, evaluate the exactitude of routine surveillance data.

目的 探讨横断面调查的优势，评价日常监测资料的准确性。

The raw data was processed by using axial, coronal and double oblique multi-planar reformation; Images obtained were graded in terms of quality with a 5-point scale(5=excellent, 4=good, 3=fair, 2=poor, and 1=nondiagnostic). In grading image quality at axial MPR, The radiologic specialists focused on the subarcuate fossa, tendon of tensor tympani, facial recess, vestibular aqueduct and pyramidal eminence, In grading image quality at coronal MPR, attention was given to the scute, crista transversa, fenestra cochleae, lateral malleal ligament and snake eyes signature of cranial nerve, In the grading of the image quality at double oblique MPR, the radiologic specialists concentrated on the malleus, incus, stirrup bone, upper bony semicircular and aquaeductus fallopii, and then to implement statistical analysis. In order to choose the minimum tube current values and the maximum pitch that can satisfy the diagnosis request, image quality of axial, coronal and double oblique reformation images was compared with different tube current groups. 15 ears of volunteers were used to test the validity with the scanning parameter. Subsequently noise, MTF and dose length product were measured by phantoms in different tube current and pitch, the parameters obtained were compared and taken into statistics analysis.

扫描模式使用临床常用的颞骨螺旋扫描方式：管电压120 kV，准直宽度20×0.6 mm，视野200 mm，重建矩阵512×512，旋转时间1 s/r，重建层厚0.6 mm，重建间隔0.3 mm，分别改变管电流(380、300、200、160、120和80 mA)和螺距(0.8、1.0和1.2)进行扫描和重建，然后对颞骨进行横断面、冠状面和双斜面多平面重组，于重组后的横断层面图像上选取弓形下窝、鼓膜张肌腱、面神经隐窝、前庭导水管和锥隆起5个解剖结构，冠状面重组图像上选取盾板、横嵴、蜗窗、面神经的蛇眼征和锤骨外侧韧带5个解剖结构，双斜面重组图像上选取锤骨、砧骨、镫骨、上骨半规管和面神经管5个解剖结构，在双盲的情况下由放射学专家分别对各管电流和螺距下扫描的重组图像进行评分，随后进行统计学处理，从中筛选出满足诊断要求的最低管电流值和最大的螺距，分别采用患者25例(15耳)用该管电流值和螺距验证其可行性；然后利用模体分别测试各管电流和螺距下的图像的空间分辨率、噪声及其剂量长度积，并对测试所得参数数值进行比较和统计学处理。

Because of these changeable elements, the novels could not be pure revolutionary works, and they embody the dual characteristics of both the individualism of the May 4th Movement and the proletariat literature, The emergence is a fortuity of a transverse section of history and society, as well as an inevitability in the process of the development of politics and literature in modern China.A.

在由这些变动性要素构建的特定背景下，左翼"革命加恋爱"小说模式必将不会是完全意义上的革命文学，而体现出五四个性主义文学和无产阶级革命文学的双重体征。它的诞生既源于一个特殊社会历史横断面的偶然，同时又是中国现代社会政治演变及文学自身发展总进程的必然。

I can not make it blossom and suits me

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
