查询词典 posterior pereion

Although classic neuroimaging features of RPLS with involvement of the posterior head regions are easily recognized, features that may generally be regarded as atypical were often present in our patients, such as significant anterior involvement, cortical lesions, recurrent RPLS episodes, foci of permanent injury, hemorrhage into lesions, and unilaterality (Figure 1). High signal intensity on T2-weighted image lesions can occur in regions other than the parieto-occipital areas, frequently involving the frontal lobes, basal ganglia, thalami, or brainstem.

可逆性后部白质脑病综合征典型的神经影像学表现为大脑后部受累，尽管这一点很早就被公认；但可逆性后部白质脑病综合征不典型的神经影像学表现，在本文的患者中则更常见，如：大脑前部明显受累、皮层出现病灶、可逆性后部白质脑病综合征再次发作、脑永久性损伤灶形成、病灶内出血、仅见单侧病灶（图1）；T2像常可于额叶、基底节区、丘脑、脑干等顶-枕叶以外的区域见高信号病灶。

AbstractAIM: To study the changes of refractive status and axial length in chicken form deprivation myopia and its recovery model, to observe the metamorphism of posterior sclera and to lay foundation for investigation of axial myopia pathogenesisMETHODS: Twenty-five newly incubated chicken were selected. Their left eyes were covered with semi-translucent membrane to deprive form perception for 14 days (form-deprivation group), or covered for 11 days followed by uncovered for 3 days. Unoccluded eyes in either group served as control eyes respectively. Retinoscopy and A- ultrasound were conducted to collect the refraction and axial length data.

目的：研究雏鸡形觉剥夺性近视眼及形觉剥夺性近视眼恢复模型的屈光状态和眼轴长度的变化，并观察后极部巩膜的形态学改变，为探讨轴性近视的发病机制打下基矗方法：选用新孵出的普通肉食家鸡25只，采用半透明薄膜眼罩遮盖的方法对左眼进行形觉剥夺14d或遮盖11d后，去遮盖3d。

Less difference in stability was observed than was predicted between specimens receiving multilevel discectomy versus multilevel corpectomy, regardless of whether specimens were left unplated, plated anteriorly, or fixated with combined anterior/posterior instrumentation.

标本接受多节段椎间盘切除与多节段椎体切除之间观察到的稳定性上的差异，比预想的要小，无论是没有进行钢板固定的标本，还是前路钢板或联合前后路内固定者都是如此。

A character-codes model based pattern recognition method by using amplitude data of targets frequency response is proposed after the establishment of high frequency response equation of radar targets. The method uses the same unvariant character-codes to express the same target of different angles and uses sequential separating of regions of target's reference variables to obtain multiple coding vectors of all regions for every target. The category and pose of target can be determined after a two-staged classification processing such as coding processing of target range profile data and errors correcting processing of coded data. The two-stage classification results are used to target identification as posterior hypothesis to be tested by sufficient convincing and necessary convincing. The character-codes model based pattern recognition method is also adaptive to variation of target angles and controllable in error probability. Time-consuming and complicated iterative computation is not necessary in the train process of pattern recognition.

首先建立了雷达目标的高频频率响应方程，这种方程将目标多散射中心理论与目标局部谐振理论有机地结合起来；进而提出了目标多频响应结构成像方法，这种方法将瑞利区频率响应或谐振区频率响应曲线的不同部位用各种不同的近似方法去逼近，通过特征谱估计方法将目标的局部频响特征与宽带距离响应特征结合起来；然后提出了一种基于姿态角变化区域的序贯划分与多模匹配的特征编码识别方法，这种方法具有能适应目标姿态角的变化以及能控制识别的差错概率α等优点，在目标识别时只需要目标在少数有限个频率激励下的幅频响应数据。
