光子

The scintillators absorb the X-rays and convert them into visible light photons that then pass onto the photodiode array.

这个闪烁物可以吸收 X 射线并将他转化成可见光光子，然后进入光电二极管阵列。

A: There are no planetary alignments in the next few decades, Earth will not cross the galactic plane in 2012, and even if these alignments were to occur, their effects on the Earth would be negligible.

答： 在未来的几十年之内都不会有行星连接现象，地球也不会在2012穿过光子带，而且，即使行星出现了链接现象，它们对地球的影响是可以忽略不计的。

On the other hand, radionuclide myocardial perfusion imaging using single-photon computed tomography is a well established modality for the functional assessment of coronary artery disease.

相反的，同位素心肌血流单光子断层造影在冠状动脉疾病功能面的评估的效益则已是众所公认的。

The cavity field spectra will be multi peak structure and the peak number increases quickly with the field intensities when the initial field is in superpositions of number states.

当初始光场为光子数态的叠加态时，腔场谱在强耦合情况下一般为多峰结构，峰的个数随着初始平均光强的增大而增加。

The radiation dose of photon was 40~50Gy and the dose of fast neutron was 8~12Gy.

光子照射剂量为40～50Gy，快中子照射剂量为8～12 Gy。

The last big question on Hollis's research agenda -- whether the cells will reset after having fired -- may not even matter in the group's latest vision for a handheld biosensor: a proposed optical-electronic box would read the photons emitted by a swappable and disposable biosensor chip, which would cost just a few dollars.

在霍利斯的研究日程表上，最后一个大问题在于细胞在发光后是否能够重新设定，按照研究小组最近对手动探测仪的设想，这个问题可能并不太重要：人们拟利用光电盒读取可交换的一次性生物探测芯片发出的光子，而光电盒只需要花费几美元。

However, MC method is timeconsuming due to the calculations of a large number of photons propagation in tissues.

为了得到足够的仿真精度，MC方法通常需要仿真大量光子包在生物组织中的传输过程，这个过程是相当耗时的。

By comparing the electron gain of the prepared silicon microchannel plate with conventional one,we found the electron gain of Si MCP was larger than glass MCP.Though there were some problems to be solved in the manufacture of electron multiplier of Si MCP,it was expected that Si MCP would be a new approach to enhance the performances of MCP and the quality of image devices.

引言 微光夜视、高灵敏度粒子成像探测和光子计数、大屏幕快速图像显示以及X射线诊断等系统，已在现代武器装备、空间技术和核辐射探测等领域中得到广泛应用，其中微光图像增强器件的核心部件之一就是二维阵列式通道电子倍增器件微通道板 MCP Microchann

For the present work, we pointed out that, as the basic unit for classical electromagnetic field, electromagnetic element-wave should be a new kind of matter which can also be called "quasi-photon".

今天，我们还特别指出：&电磁基波&作为经典电磁场的基本单元，应该是一种新的物质，亦可称作&准光子&。

Since the basic unit of quantum electromagnetic field is obviously a kind of matter in structural realism, it would be an interesting question whether the basic unit (electromagnetic element-wave) of classical electromagnetic field is also a kind of matter.

在结构实在论中，量子电磁场的基本单元——&光子&显然是一种物质。那么，经典电磁场的基本单元——&电磁基波&是否也是一种物质呢？

I can not make it blossom and suits me

我不能让树为我开花

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
