查询词典 optic

Retinotopic inputs to the optic tectum have 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。

Sperry showed that the regenerated retinal axons always innervated the original sites of termination in the optic tectum. This experiment strongly disprove the resonance hypotheses proposed by Paul Weiss, who suggested that the nerve growth and synapse formation are largely random events, and the precision of connections between nerve cells emerged by selectively eliminating the inappropriate connections, only at later developmental stage.

Sperry的实验在支持Cajal假说的基础上，进一步明确发育过程中轴突的生长及突触的形成具有内在决定性，并且有力地反驳了当时占主流地位的由Paul Weiss于1930～40年代提出的resonance hypothesis，后者认为轴突的生长和突触的形成大多是一些随机事件，成年脑中的精确联系是通过对随机形成的不恰当联系进行选择地消除形成的。

T was later transiently expressed in pharyngeal arches, and in pectoral fin buds. IGFBP-3 mRNA is predominantly and persistently expressed in the developing otic vesicle. IGFBP-3 is also expressed in optic stalk, retina, pineal gland, tegmentum in midbrain, anterior pituitary and midline floor of hypothalamus.

GFBP-3 mRNA 持续而强烈地表达在发育中的内耳，它也表达在眼睛的视杆和部分视网膜细胞，松果腺以及脑垂体前部、中脑脑盖和下丘脑的基底中央等脑组织。

Fiber optic cables are not susceptible to electronic noise and so have much lower error rates than normal telephone wire and cable.

光缆对电子噪音不敏感，所以比通常的电话线和电缆有较低的误差率。

To make a preform of the tellurite optic fiber, we use a mode to cast the glass and use machining method to get the preform.

通过模具结构设计，采用整体浇铸和机械加工相结合的方法来制作光纤预制棒。

Electro-optic theodolite is one of the most important measurement.

1引言光电经纬仪是武器靶场最为重要的测量手段之一，具有直观性强、测量精度高等特点，是获得导弹外弹道参数的主要途径。

Just as the 1889 Paris Exposition gave rise to the EiffelTower, this world's fair will leave behind a structure that embodies its vision of the future: a transoceanic "railroad" of high-speed fiber-optic links.

年的巴黎博览会留下了埃菲尔铁塔，这一次的世界博览会也会留下一个结构来代表未来的远景：越洋的高速光纤电缆——"铁路"。

And that backstage — a high-speed telecommunications pipeline — is the exposition's true showpiece. Just as the 1889 Paris Exposition gave rise to the Eiffel Tower, this world's fair will leave behind a structure that embodies its vision of the future: a transoceanic "railroad" of high-speed fiber-optic links.
