Though there are multiple sites like deep gray matter and posterior fossa (middle cerebellar peduncles,cerebellum,brainstem) that are also involved, the callosal lesions are more distinct.

虽然病变可以见于多处，如深部的脑灰质、后颅窝，胼胝体的病变是最特殊的。

An image of the posterior fossa in the transaxial plane is obtained by angling caudally from the plane used to visualize the ventricular atrium.

后颅窝横切面的图像是由从用于显示脑室腔的切面向尾端偏角调节而获得的。

An image of the posterior fossa in the transaxial plane is obtained by angling caudally from the plane used to isualize the entricular atrium.

后颅窝横切面的图像是由从用于显示脑室腔的切面向尾端偏角调节而获得的。

Results: The lesion located in the left choana region and left sphenoidal sinus of this case involved the left pharyngeal mucous space, left infratemporal fossa and its adjacent bone structure. CT showed that the rhinoscleroma in granulomatous stage was a soft mass which was irregular in shape, with a well-defined margin, inhomogeneous density and bone destruction. MRI showed heterogeneous hyperintensity on T1WI and isointensity on T2WI with an intermediate heterogeneous enhancement.

结果：病变起源于左侧后鼻孔及左侧蝶窦区，累及左侧咽粘膜间隙、左侧颞下窝及邻近骨质；结合本病例及文献复习，肉芽肿期鼻硬结病CT表现为不规则软组织肿块，轮廓清楚，密度不均匀，可见骨质破坏，残存骨质呈硬化改变；MRI表现为T1WI高信号T2WI等信号影，信号不均匀，增强后中度不均匀强化。

Results:(1) Spin-echo sequence included axial, coronal and sagittal images. In T1-weighted images,the medulla oblongata is isointense,the cistern is hypointense; in T2-weighted images,the medulla oblongata is isointense, CSF shows hyperintense, and the arteries of posterior fossa appear hypointense flow voids. The cisternal cranial nerves are not clearly demonstrated in the routine spin-echo images. In 3D-time of flight images, the brain tissue shows isointense, CSF is hypointense, the artery shows hyperintense,and the cranial nerves show linear isointense.

2，结果：(1)常规SE序列横断面、冠状面及矢状面T1WI显示延髓等脑组织呈等信号，延髓周围池脑脊液呈黑色低信号，T2WI显示脑组织为等信号、脑脊液为白色高信号，脑底动脉在池内高信号背景下由于&流空效应&而表现为低信号，常规序列由于成像参数关系而不能直接显示脑池内颅神经；三维时间飞跃(3D-TOF)成像序列显示脑组织为等信号，脑脊液为低信号，而脑池内脑底动脉则呈高信号、脑池内后组颅神经为线状等信号。

Objective To study the quantitative changes in the exposure of the middle fossa and the superior clivus via a retrosigmoid suprameatal approach.

目的 量化研究在乙状窦后入路基础上磨除内耳道上区骨性结构前后显露颅中窝、上斜坡的变化情况。

The median part of the middle fossa, the lateral part of the superior clivus and the trigeminal nerve in the Meckel cave could be exposed via a retrosigmoid suprameatal approach.

采用乙状窦后经内耳道上入路，可将乙状窦后入路的手术野扩大到颅中窝的中线侧和上斜坡侧方，并可显露Meckel腔内的三叉神经。

The dose of the craniospinal irradiation was 36Gy and the total posterior fossa dose was 54Gy.

全脑全脊髓剂量36Gy，后颅窝局部加量至54Gy。

According to our present broadcasting situation,the thesis proposes using new technology to update and reform the present HFC. It also suggests broadcasting using self-advantage and arranging EPON in order to win the supermarket.

论文从我国广电的现状出发，结合实际，积极倡导采用新技术更新、改造我国现有的HFC网络；倡导广电现阶段利用自身优势，部署EPON网络来赢取市场。

A new general kinetic equation was derived in which the effect of the removal of condensation water was taken into account completely, and was applied to the polyesterification kinetic study of AA/HPHP and AA/NPG. It was found that the reaction order of self-catalyzed polyesterification was not constant. For these polyesterifications, the reaction order was 2.5 at a low temperature, while 3.0 at a high temperature.

考虑缩合水的排除对反应体系的影响，用体积浓度单位推导出一个新的聚酯反应总包动力学方程，并应用到AA/HPHP和AA/NPG两个聚酯化反应的动力学研究中，研究发现，自催化聚酯反应的反应级数并不是固定值，对于AA/HPHP和AA/NPG两个聚酯化反应而言，低温时反应级数为2.5，高温时反应级数为3.0。
