Objective To condcut preliminary study of the value of DTI(diffusion tensor imaging) in human cervical spinal cord.目的探讨弥散张量成像(diffusion tensor imaging,DTI)在颈髓中的应用价值。
Angle was the first risk factor of fatigue of extensor carpi ulnaris(ECU),ED and FCR.角度是主动肌尺侧腕伸肌(extensor carpi ulnaris,ECU)、ED和拮抗肌FCR疲劳的首位危险因素。
Results Tensor fasciae latae showed itself fusiform,length .~7. cm,width .~. cm,thickness 0.8~. cm,and iliotibial tract果阔筋膜张肌呈长梭形,长.~7. cm,宽 .~. cm,厚0.8~. cm,髂胫束长~8 cm,宽~7cm,厚0. cm,由臀上神经下支支配。
Results The MPF and MF of extensor digitorium(ED),flexor carpi radialis(FCR)and flexor carpi ulnaris(FCU)were lower at h果指伸肌(extensor digitorium,ED)、桡侧腕屈肌(flexor carpi radialis,FCR)和尺侧腕屈肌(flexor carpi ulnaris,FCU)的MPF和MF在频率负荷高剂量组较低剂量组降低,组间比
Tensor product of spinor space can extend low dimension to higher dimentinal space.随后通过定义张量积的概念和张量积上的增广结构，我们可以把低维的情形推广到高维。
