放大

Simply stated: A loupe with a lower magnification factor, will have a larger field of view, and vice versa.

视场的大小和放大倍率也有联系，简单的说：手术放大镜的放大倍率越小，视场范围就越大，反之亦然。

The key of image magnification technique is to ensure that the definition is as good as the initial image.

图像放大技术的关键在于使放大后的图像尽可能地保持原始图像的清晰度。

The telescope that Galileo built in the late 1500s had the magnifying power of a pair of inexpensive binoculars available in any Wal-Mart, but it was enough to open up a new world.

伽利略在15世纪晚期制造的望远镜的放大倍数相当于现在在任一家沃尔玛超市都可以买到的一对廉价双筒望远镜的放大倍数，但它足以打开一个新世界。

Finally designs has the tonality control circuit the audio frequency amplification electric circuit to have very well chooses the frequency function, with pronunciation magnifying power.

最后设计出来的带有音调控制电路的音频放大电路具有很好的选频功能，和语音放大能力。

In this system , microvolt amplifying circuit module and isolation amplifying circuit module is used in external circuit, improving exactitude of plasma diagnosed, and overcoming separate disturbance effectively .

该系统的外围接口电路采用微伏放大模块和隔离放大模块，提高了信号采集的精度，并有效克服了各种干扰。

This paper is to study the low noise amplifier, the primary stage of the RF/microwave receiver, The function of LNA is to amplify the uV vohage signal received by antenna.

低噪声放大器是对来自天线的微伏级信号进行放大的射频接收端的放大模块。

In the measure amplification circuit, direct-current or low frequency signal come from a common sensor , conveying in only rhyme fashion way after amplification, In typical situation, serviceable signal maximum amplitude probable only have a certain number or amount millivolt, but common mode noise suppression may be up to several volt, as a result it is significant to the factor of the amplification input drift and noise etc for total precision, the amplification in itself common mode restraints features is also equally binding problem.

在测量用的放大电路中，一般传感器送来的直流或低频信号，经放大后用单端方式传输，在典型情况下，有用信号的最大幅度可能仅有若干毫伏，而共模噪音可能高到几伏，故放大器输入漂移和噪声等因素对于总的精度至关重要，放大器本身的共模抑制特性也是同等重要的问题。

F the magnifying effect of Moire which consists of grating and laser interferometric fringes, the small displacements of interferometric fringes,which are caused by small angular change,are magnified several thousands times,thus,the sensitivity of measuring system is greatly improved.

其原理是用一个光栅与激光干涉条纹组成莫尔条纹，利用莫尔条纹的放大作用将干涉条纹在微小角变下的微小移动放大几千倍，从而大大提高了测量灵敏度，使测量精度提高到0。

It was found greater expression of NRP2-1 and NRP2-2 in pituitary, ovary, uterus and oviduct of ruttish Erhualian than corresponding tissues of ruttish Duroc, which suggested enhancing expression of NRP2 was favorable to increasing litter size. But the difference of NRP2 expression was not significant between two breeds, which suggested the key phase that NRP2 affected litter size was not oestrum probably, or NRP2 could enlarge cell signals and finally affect litter size ascribe that it was the receptor of nerve axon guidance factors.

NRP2-1和NRP2-2在发情期二花脸卵巢、子宫、输卵管中的表达量均大于杜洛克相应组织的表达量，推测NRP2表达水平高可能有利于提高产仔数，但两品种间表达差异不明显，推测NRP2影响产仔数的关键阶段可能不是猪的发情期；另外，NRP2 是神经轴突介导因子的受体，这些神经轴突转导的信号往往有级联放大的功能，虽然NRP2-1和NRP2-2在二花脸和杜洛克卵巢、子宫、输卵管中的表达差异不大，但二花脸有可能通过神经系统转导信号的级联放大最终引起一些效应激素或蛋白的急剧增加，从而提高排卵率或产仔数。

A single stage amplifier was used outside the loop cavity to increase the output power, and the influence of amplification on laser quality was analyzed.

环形腔输出后加入单级光放大提高输出激光的光功率，分析了放大对激光性能的影响。

Methods: Five patients with parkinsonism or dystonia were assigned to general anesthesia using an modified endotracheal tube.

本实验依照人体实验之相关规定进行，五位患有帕金森氏症或肌张力异常的病人接受神经立体定位手术。
