斜视

Intermittent exotropia exophoria lies and concomitant exotropia a transition between the esotropia.

间歇性外斜视是介于外隐斜和共同性外斜视之间的一种过渡型斜视。

Intermittent and constant exotropia are two main kinds of exotropia of acquired comitant exotropia.

间歇性外斜视和恒定性外斜视是后天性共同性外斜视中最常见的两种类型。

Objective To analyze correlation of the age of onset of visual impairment with direction deviation of (eso-or exotropia) and to explore a prevalence of dissociated vertical deviation.

目的 主要总结分析知觉性斜视的类型与视力障碍发病年龄的关系及知觉性斜视中分离性垂直性斜视的检出率。

In the past, the study on their stereopsis was respective or combined, in spite of some constant exotropia may represent decompensated intermittent exotropia.

以往对其立体视的研究都将间歇性外斜视和恒定性外斜视分开进行，或对整个后天性共同性外斜视进行研究，忽略了恒定性外斜视有一部分为间歇性外斜视失代偿发展而来。

Strabismus is most commonly described by the direction of the eye misalignment; common types of strabismus are esotropia, exotropia, hypotropia, and hypertropia.

斜视最常见的定义是根据眼位偏斜的方向，斜视常见的类型是内斜视，外斜视，下斜视，和上斜视。

Strabotomy could completely or partly eliminate diplopia, especially it could correct the restricted strabismus in the primary position and in the read location.

结论①视网膜脱离手术后斜视属于限制性斜视，其临床特征有助于指导对运动受限的肌肉做出准确判断和定位并进行斜视手术；②视网膜脱离手术后水平斜视的方向与主要牵制肌肉相反的情况由直肌下过度操作引起；③斜视手术可改善复视症状、矫正眼位。

METHODS: Divided the cases with strabismus into two groups: 36 cases underwent strabismus diorthosis under microscope using general micro equipments; and 45 cases underwent traditional strabismus diorthosis directly.

把斜视病例分为两组：显微镜下斜视矫正术组：36例各类斜视患者，均采用显微技术在显微镜下行斜视矫正术。

The esotropia was encountered when the onset of visual impairment occurred at birth or less than 1 year old of age. Exotropia predominated in more than 1 year old children and adults. DVD may also occur in association with sensory heterotropia, we should take DVD into account when planning the surgical treatment of horizontal strabismus.

屈光参差、视网膜病变、视神经损害、先天性白内障、外伤性白内障是导致知觉性斜视的主要病因；其中小于1岁与大于1岁者相比，发生内斜视的比例较大，1岁以后主要发生外斜视；知觉性斜视者可伴有DVD的存在，在水平斜视的手术中要考虑此问题。

Chirp scaling algorithm is considered more efficient and widely applicable when the bistatic SAR system is in side-look or small squint angle mode,but in large squint angle case,the errors caused by Taylor expansion are so large that the algorithm could lose its precision.In such a case,an equivalent mono-static SAR range mode which has fewer errors than Taylor expansion with large squint angle is proposed to substitute the range history of bistatic SAR.Then bistatic SAR images with large squint angles are gotten by common Nonlinear CS algorithm.The effectivity of the method is verified by Matlab simulation.

在正侧视或小斜视情况下，CS算法具有较好的聚焦性能和广泛的适用性，但在斜视角较大的情况下，该算法将散焦而不能成像，因而提出了用等效的单基地距离模型来代替双基地距离历史的方法，解决了大斜视角情况下距离模型二阶近似误差较大的问题，并结合单基地非线性CS算法，实现了在大斜视角情况下的基于GPS反射信号的双基地SAR高精度成像，最后通过Matlab仿真进行了验证。

摘 要：建立了基于gps的顺轨sar系统模型，通过将gps信号等效为chirp信号，研究了在该模式下的大斜视角chirp scaling算法。在正侧视或小斜视情况下，cs算法具有较好的聚焦性能和广泛的适用性，但在斜视角较大的情况下，该算法将散焦而不能成像，因而提出了用等效的单基地距离模型来代替双基地距离历史的方法，解决了大斜视角情况下距离模型二阶近似误差较大的问题，并结合单基地非线性cs算法，实现了在大斜视角情况下的基于gps反射信号的双基地sar高精度成像，最后通过matlab仿真进行了验证。

Means the parent directory, so this command means to execute "toolchain.sh," which is in the current directory.

代表父目录，所以这个命令就是执行当前目录下的"toolchain.sh"。

Yes,In fact,I'm on our city ream.

是的。事实上我是我们市队的。
