背景介绍前几天对一个自己造的化合物使用紫外（UV）进行全波长扫描，虽然波长是扫出来了，但是如何对每条曲线进行积分求峰的面积，以此进行下一步计算呢？软件下载Origin 2021积分教程下面是我们的一组数据，数据是从机器上直接导出来的csv格式，然后直接复制到Origin软件即可。
Name the first column: Time. The second column is named Signal 1. The third column is named Signal 2.
从外观来看，它是一个均匀分布的扇形图，扇形图被分成了好多段，外面三层是一个类型，向里是分了6层的圆形气泡图，圆的大小代表了数值的大小，再向里是圆形的堆积图，用来展示数据在总量中的占比，再向里还是扇形图，再向里是用来表达显著性差异的。

Abstract:Understanding the origin of bright shooting stars and their meteorite samples is among the most ancient of astronomy-related questions， which at larger scales has human consequences. As of today， only approximately 6% of meteorite falls have been firmly linked to their sources . Here we show that approximately 70% of meteorites originate from three recent break-ups of D > 30 km asteroids that occurred 5.8， 7.6 and less than about 40 Myr ago. These break-ups， including the well-known Karin family， took place in the prominent yet old Koronis and Massalia families and are at the origin of the dominance of H and L ordinary chondrites among meteorite falls. These young families are distinguished among all main belt asteroids by having a uniquely high abundance of small fragments. Their size–frequency distribution remained steep for a few tens of millions of years， exceeding temporarily the production of metre-sized fragments by the largest old asteroid families . Supporting evidence includes the existence of associated dust bands， the cosmic-ray exposure ages of H-chondrite meteorites and the distribution of the pre-atmospheric orbits of meteorites.
Abstract:Type Ia supernovae are cosmic distance indicators， and the main source of iron in the Universe， but their formation paths are still debated. Several dozen supersoft X-ray sources， in which a white dwarf accretes hydrogen-rich matter from a non-degenerate donor star， have been observed and suggested as Type Ia supernovae progenitors. However， observational evidence for hydrogen， which is expected to be stripped off the donor star during the supernova explosion， is lacking. Helium-accreting white dwarfs， which would circumvent this problem， have been predicted for more than 30 years， including their appearance as supersoft X-ray sources， but have so far escaped detection. Here we report a supersoft X-ray source with an accretion disk whose optical spectrum is completely dominated by helium， suggesting that the donor star is hydrogen-free. We interpret the luminous and supersoft X-rays as resulting from helium burning near the surface of the accreting white dwarf. The properties of our system provide evidence for extended pathways towards Chandrasekhar-mass explosions based on helium accretion， in particular for stable burning in white dwarfs at lower accretion rates than expected so far. This may allow us to recover the population of the sub-energetic so-called Type Iax supernovae， up to 30% of all Type Ia supernovae， within this scenario.
