纤维束

Experimental results indicate that: The AE characters of single bundle, 2-D woven and 3-D braided C/SiC composite are different because of their different structures, damage mechanisms and developing progress, which can be verified by micrographic examination on specimens' initial state and fractography.

实验研究表明：单纤维束、二维编织和三维编织C／SiC复合材料由于结构形式不同，损伤机理和发展过程不同，表现出的声发射参量的特性也不同；试件初始状态和断口的显微观察证实了该推断。

Objective To investigate the pathogenesis of the abnormal diffusion in the white matter tracts in patients with neuromyelitis optica using diffusion tensor imaging.

在视神经脊髓炎(neuromyelitis optica，NMO)患者，脑白质纤维束的扩散异常已有报道，但其分布模式及发生机制尚不清楚[1]。

It has six kinds of texture: felt-like cryptocrystallineballistic texture, fascicules ballistic texture, radiated ballistic texture, porphyritic texture,gyrated ballistic texture, replacement remnant ballistic texture.

通过镜下分析，栾川软玉的主要矿物成分为透闪石，一般含量在 95%以上，结构可分为毛毡状显微交织变晶结构、纤维束状变晶结构、放射状变晶结构、似斑状结构、旋转结构、交代残余结构。

Alternative embodiments of the insertion tool utilize severable fibers, a transparent split-mylar sheet or diaphragm, a cantilever fork, a collet assembly or an elastomeric grip collet to gently hold and release the shunt during insertion.

插入工具优选的实施例利用可分离纤维束，透明的分离聚脂薄膜片或隔膜片，悬臂叉，夹头组件或弹性爪夹头，在插入中轻轻固定和释放分流管。

Results There was significant difference in the FA values in frontal and the splenium of corpus callosum between schizophrenia patients and controls (P.05). There was a statistically significant correlation between FA values in frontal and the PANSS scores (r=0.703. P.05). DTT can not show different between patients and controls.

结果 精神分裂症患者双侧额叶和胼胝体压部的FA值与正常对照组存在显著性差异(P.05)，额叶FA值与PANSS量表评分之间存在正相关性(r=0.703，P.05)，纤维束成像技术不能显示病例组和对照组的差别。

The margin of the white matter tract become more clearly with the increasing of the number of gradient encoding directions, especially the detail of the brain stem. But the measured FA of the centrum semiovale, genu and splenium of corpous callosum, the internal capsule, thalamus and the pons with 6, 13 and 21 diffusion gradient encoding directions showed no statically difference.

随着弥散梯度编码方向的增加，FA图质量提高，对白质纤维束细节的显示也更清楚，尤其是对脑干结构的分辨，但成像时间延长；3种不同弥散梯度编码方向的DTI扫描方案所观察到的半卵圆中心、胼胝体膝部、胼胝体压部、内囊、丘脑及桥脑的FA值不存在统计学显著性差异。

Results DTI demonstrated that the influences of space-occupying effect and infiltrating invasion of brain tumor and peritumoral edema on white matter fiber tracts could be divided into three types: displacement, syzygium and destruction.

结果 DTI显示脑白质纤维束受脑肿瘤占位效应、浸润和瘤周水肿等影响，而表现为移位、融合和破坏三种形式，可合并两种或三种形式存在。

Based on anisotropic elastic theory,the linear and nonlinear constitutive equations of twistless fiber bundle s were worked out by utilizing elastic mechanics.

应用弹性力学方法，根据各向异性弹性理论，导出非加捻纤维束线性和非线性本构方程。

A few were found among fiber tracts of the vagal trunk, these cells were indistinquishable in shape from the c...

此外，少量的标记细胞见于迷走神经干的纤维束中，这些标记细胞的形态与结状节的基本相同。

The cerebellar hemispheres oppose one another in the midline due to absence of vermis.

由于缺乏小脑蚓部，双侧小脑半球在中线上不连续，峡部和中脑前后径较小，这可能是由于小脑上脚缺乏十字交叉的纤维束。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
