眼后的

Paired Samples T test revealed that both the LT and VL decreased (P.01), the AD increased (P.01) after cycloplegia regardless of their refractive state. The AL increased for hyperopic eyes (P.05) and decreased for myopic eyes (P.01) after cycloplegia. For hyperopic eyes, the major keratometer K1 increased (P.05) while for myopic eyes, the major keratometer K1(P.05) and minor keratometer K2 (P.01) decreased after cycloplegia. The mean corneal power of zones 5 mm (MD5) and 7 mm (MD7) decreased with myopic eyes decreased dramatically (P.01). The mean refractive power of the lower half vertical meridian is greater than that of upper half; and the mean refractive power of the lateral half of the horizontal is greater than that of the medial half.

结果：不论远视眼、正视眼还是近视眼在睫状肌麻痹后前房加深（P.01），晶状体变薄（P.01），玻璃体腔径缩短（P.01）；但远视眼睫状肌麻痹后眼轴增长（P.05），近视眼眼轴缩短（P.01）；远视眼睫状肌麻痹后角膜曲率K1增加（P.05），近视眼睫状肌麻痹后除K1降低外（P.05），K2以及以角膜中心点为中心，直径为5mm、7mm的环平均角膜屈光度（MD5、MD7）均降低（P.01）；此外，垂直径线上方的平均角膜屈光度小于下方的平均角膜屈光度而水平径线鼻侧的平均角膜屈光度小于颞侧的平均角膜屈光度（P.01）。

The two treatment groups were both lower than control group; the atropine group was lower than the tropicamide group;(2) the changes of axial length before and after using eyedrop. there was no evident change in the atropine group; the axial length was obvious prolonged in tropicamide group and control group.(3) the phengophobia symptom.

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.

Nowadays most of researches on the multicast routing are how to generate multicast tree. In case of multicast tree failure, there need to re-route all of nodes behind the failure point so much as re-build the whole tree, this will deteriorate Quality-of-Service, on the other hand, it is insufferable in some multicast applications. We proposed a Fault-Tolerant multicast scheme to resolve this problem. Our scheme creates backup paths crosswise in the ramose node. It can reduce additional cost greatly and recover the failure of multicast tree rapidly.

现在关于多播路由的研究大多著眼于多播树的生成，一旦多播树出现故障，就需要对故障点以下的所有多播接收节点进行重新路由甚至对整个多播树进行重新构造，这一方面降低了服务质量，另一方面有些多播应用不允许长时间的中断，对此本文提出了一种多播容错方案，采用在分枝节点之间建立备份路径的措施，可以在很大程度上减少额外的代价，能够在最快的时间内恢复多播树的故障，并使得恢复后的多播树形状基本上没有改变。
