Inspiron XPS – The very first XPS laptop was a very heavy desktop-replacement laptop starting at 9.06 pounds without a power supply (which added 2.5 pounds). This was because it was offered with either a 3.4 GHz desktop Pentium 4 HT "Prescott" processor, or the "Gallatin" Pentium 4 Extreme Edition processor at the same clock speed, which gave ...

2019年4月14日 · The first XPS PCs started showing up on computer store shelves in 1993 and were available in desktop and tower PC form factors. The first such desktop PC was the Dell Dimension XPS 466V.

2025年2月5日 · When Was The First Dell XPS Laptop Released? The first Dell XPS laptop was released in 1993, a time when laptops were just starting to gain popularity. This pioneering laptop was called the XPS 603, and it was designed to be a high-performance machine that could handle demanding tasks like video editing and 3D modeling.

A few years later in 1967, Siegbahn published a comprehensive study of XPS, bringing instant recognition of the utility of XPS and also the first hard X-ray photoemission experiments, which he referred to as Electron Spectroscopy for Chemical Analysis (ESCA). [3]

2024年3月4日 · The XPS 15 9530 was also the first XPS notebook to use the 37 W Intel Core i7-4700HQ Haswell processor, which offered much better performance and thermal headroom than the ULV CPUs used in the XPS 13 range.

2017年12月1日 · XVIVO Perfusion has installed the first XPS™ in China. The purpose is to start an EVLP (Ex Vivo Lung Perfusion)-study at Shanghai Pulmonary Hospital. The study is designed to complement existing EVLP data, with Chinese data.

This first guide outlines steps appropriate for determining whether XPS is capable of obtaining the desired information, identifies issues relevant to planning, conducting and reporting an XPS measurement, and identifies sources of practical information for conducting XPS measurements.

XPS, closed cell polystyrene foam, is a form of thermal insulation, the very first foam used for thermal insulation. The closed-cell polystyrene foam was developed in 1941 during World War II by the Dow Chemical Company, and patented in 1944.

2012年7月25日 · The first XPS 15 (L501x/L502x) was a nice change of pace from previous Dell designs, but it wasn’t really close to Apple in terms of overall design.

XPS, 全称为 X-ray Photoelectron Spectroscopy （X射线光电子能谱）, 早期也被称为 ESCA (Electron Spectroscopy for Chemical Analysis),是一种使用电子谱仪测量X-射线光子辐照时样品表面所发射出的光电子和 俄歇电子 能量分布的方法。 XPS可用于 定性分析以及半定量分析, 一般从XPS图谱的峰位和峰形获得样品表面元素成分、化学态和分子结构等信息，从峰强可获得样品表面元素含量或浓度。 2. XPS表征的是样品的表面还是体相？ 为什么？ XPS是一种典型的 表面 …
