查询词典 optic

Visual responses of 80% tectal cells were reversibly blocked by NMDA antagonist CPP, and those of 20% cells by muscarinic antagonist atropine, suggesting that retinotectal pathway in toads may contain two groups of optic fibers that use glutamate and acetylcholine as transmitters, respectively.

视网膜-顶盖是视觉信息进入脑的第一站，但是对两栖类视网膜-顶盖投射所用递质却长期含混不清；另一方面，峡核是次级视觉中枢，与顶盖间存在着密切的神经联系，虽有实验对峡核-顶盖投射的突触连接性质进行了研究，但却未见峡核-顶盖投射所用递质方面的报道。

Retinotopic inputs to the optic tectum hae been thoroughly mapped, but now Sato et al. map tectal efferents that project to the premotor reticulospinal system of the hindbrain.

视网膜区域定位输入信号到视顶盖已经得到了充分的定位，现在Sato等人绘制了覆盖层传出神经，它们投射到后脑的网状脊髓系统。

For the propose of finding high energy mid-infrared laser output, a compound cavity kalium titanyl arsenate optical parametric oscillator pumped by an electro-optic Q-switched flash-lamp-pumped 1064nm Nd:YAG laser was experimentally studied.

为了得到高能量中红外激光输出，对电光调Q灯抽运1064nm Nd： YAG抽运复合腔砷酸钛氧钾光学参变振荡器作了实验研究，在工作频率1Hz时得到OPO输出单脉冲能量36mJ，信号光脉宽10ns，闲频光波长3407nm，能量11mJ。

Many studies about central nervous system have been carried out using the transection of optic nerve as model system.

电刺激作为一种可靠的神经恢复方法，被广泛应用于外周神经系统中。

JAK-STAT signal transduction pathway was involved in the pathological processes in the retinal after transection of the optic nerve.

Janus激酶-信号转导子与转录激活子信号转导途径可能通过STAT3蛋白的活化，参与视神经切断后视网膜内的病理改变过程。

The albinism is characterized by hypopigmentation of the skin and hair and the ocular findings of reduced iris pigment with iris transillumination, reduced retinal pigment, foveal hypoplasia with significant reduction in visual acuity (usually in the range of 20/50 to 20/400), nystagmus, and increased crossing of the optic nerve fibers.

白化的特征有：皮肤与头发的色素减退以及一些眼科症状，包括虹膜透照显示出的虹膜着色减弱、视网膜着色减弱、中央凹发育不良且视觉灵敏度显著减弱（通常在20/50至20/400的范围）、眼球震颤和视神经纤维交叉增加。

Diagnosis/testing. A diagnosis of ocular albinism is probable in the presence of congenital nystagmus, iris translucency, and significant hypopigmentation of the ocular fundus periphery in males with normal skin pigmentation and foveal hypoplasia, reduced visual acuity, and aberrant optic pathway projection, as demonstrated by crossed asymmetry of the cortical responses on visual evoked potential. X-linked inheritance is documented by either a family history consistent with X-linked inheritance or the presence of typical carrier signs (irregular retinal pigmentation and partial iris transillumination) in an obligate carrier female.

诊断/检测。对于皮肤色素沉着正常、中央凹发育不全、视敏度降低以及视径投射异常（VEP，表现为视觉诱发电位中皮层反应的交叉不对称）的男性患者，当存在先天眼球震颤、虹膜半透明以及显著的眼基底层边缘色素减退的症状时，可被疑似诊断为眼白化病。X连锁性遗传则以存在与X连锁遗传一致的家族病史，或在一个应当为携带者的女性中存在典型的携带者迹象（视网膜色素沉着不规则以及部分虹膜透射）而被确认。

And give out ways to improve transmittable uniformity of fiber-optic inverter.

提出提高光纤倒像器透过率及改善均匀性的几种方法。

The outcome of visual acuity was poorer in patients with the following conditions:no light perception after trauma（P=0.0069）,loss of consciousness（P=0.003）,fracture of the opticcanal,and absence of VEP.Conclusion Traumatic optic neuropathy included diˉrect and undirect injury type.

伤后视力无光感比有光感以上视力（P=0.0069）、伤后有昏迷比伤后无昏迷（P=0.0030）、伤后视神经管骨折比无骨折、视觉诱发电位检查熄灭型比非熄灭型最终视力的恢复危险度增加。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
