~我也是新人，我在试着做图时发现那些符号和等效电路上的元件名称相同！ ~~ CPE-T单位是F，W1－R的单位是Ohm吧？ CPE-P, W1-T, W1-P是无量纲数么？ 其意义是什么？ 还有就是楼主你是用什么型号的电化学工作站测的图？ 图很漂亮！ ~~ 还有就是楼主你是用什么型号的电化学工作站测的图？ 图很漂亮！ ~~ Zsimpwin 软件分析也挺好用的哈。 分析出来的时候单位也都是有的。 你看看吧. Zsimpwin 软件分析也挺好用的哈。 分析出来的时候单位也都是有的。 你看看吧. …

Q is CPE (Constant Phase Element) when you have (suppose to have) a depressed semicircle (an arc of circle) in Nyquist plot. So, it is another issue not admittance in first glance, but it could...

CPE-T and CPE-P in Zview: what do the CPE-T and CPE-P values correspond to? Looking forward to hear you guys. Thanks! CPE-T: Amplitude. If CPE-P = 0, then amplitude = [ohm]. If CPE-P = 1, then...

CPE全称为Constant Phase Angle Element，即常相位角元件。 实际上，CPE指的是具有同一种特征的电路元件， Warburg阻抗 也属于CPE的一种。 那么，到底是什么特征呢？ 可以看一篇1988年发表在 PRB 的文章中的一句话： 这篇文章的DOI号是10.1103/PhysRevB.37.3434。 可以看到，所谓 常相位，意思是阻抗与1/jω的幂具有相关性。 这里的power-law function就是幂函数。 幂的意思就是乘方。 另外，这种幂相关性是由于电极界面上的不规则形状所导致的动力学弛豫。 更重 …

单光子发射计算机断层成像术(Single-Photon Emission Computed Tomography，SPECT)和正电子发射断层成像术(Positron Emission Tomography，PET)是核医学的两种CT技术，由于它们都是对从病人体内发射的γ射线成像，故统称发射型计算机断层成像术(Emission Computed Tomography，ECT)。

Single-photon emission computed tomography (SPECT, or less commonly, SPET) is a nuclear medicine tomographic imaging technique using gamma rays. [1] It is very similar to conventional nuclear medicine planar imaging using a gamma camera (that is, scintigraphy ), [ 2 ] but is able to provide true 3D information.

SPECT(Single Photon Emission Computed Tomography)：是 单光子发射型计算机断层成像 的英文字头缩写。 PET(Positron Emission Computed Tomography)：是 正电子发射型计算机断层成像 的英文字头缩写。

Single photon emission computed tomography (SPECT) is a medical imaging technique that is based on conventional nuclear medicine imaging and tomographic reconstruction methods. The images reflect functional information about patients similar to that obtained with positron emission tomography (PET).

Single photon emission computed tomography (SPECT) is a tomographic imaging technique that visualises gamma-rays emitting radiopharmaceuticals introduced to the patient. SPECT along with positron emission tomography (PET) is the main molecular (functional) imaging method used for localisation of tumours, infections, cardiac or brain functions.

2024年9月29日 · Design. SPECT machines combine an array of gamma cameras (ranging from one to four cameras) which rotate around the patient on a gantry. SPECT may be also combined with a separate CT machine in a form of hybrid imaging; single photon emission computed tomography-computerized tomography (SPECT-CT) mainly for the purposes of attenuation correction and anatomical localization 1.
