Isochronous mass spectrometry in storage rings is a successful technique for the precision mass measurements ofthe nuclides with half-lives down to tens of microseconds[1]. Since the isochronous condition =t greatly reducesthe influence of the velocity difference on the ion revolution periods, the revolution period difference ΔT =T ??TRof a stored ion with respect to a reference time TR is directly related to its mass-to-charge ratio difference Δ(m=q),written in the first order as:

象雄半细毛羊是西藏阿里地区多年来培育的适应高原环境的本地品种。现阿里地区存栏约3万只左右,是当地农牧民喜爱的食品。为进一步研究其在高原环境下生长的羊肉品质,并结合相类的羊肉进行比对研究。实验部分按照国家肉与肉制品相关标准进行检测,主要检测指标为水分、灰分、微量元素和氨基酸水平等。对象雄半细毛羊肉质品质进行了分析,并与澎波半细毛羊、云南半细毛羊、青海半细毛羊等进行了肉质常规营养和氨基酸含量分析对比,结果表明象雄半细毛羊蛋白质含量17.95%,脂肪含量达11.27%,水分含量为68.53%,氨基酸总量17.76±1.12 g/100g。必需氨基酸和肉风味相关氨基酸含量均高于其余三种羊肉;四个品种的钙含量相似,但铁锌镁含量不相同。

We present the observational results from a detailed timing analysis of the black hole candidate EXO 1846-031 during its outburst in 2019 with the observations of Insight-HXMT,NICER and *** outburst can be classified roughly into four different ***-C quasi-periodic oscillations(QPOs)observed by NICER(about 0.1-6 Hz)and Insight-HXMT(about 0.7-8 Hz)are also reported in this ***,we study various physical quantities related to QPO *** QPO rms-frequency relationship in the energy band 1-10 keV indicates that there is a turning pointing in frequency around2 Hz,which is similar to that of GRS 1915+105.A possible hypothesis for the relationship above may be related to the inclination of the source,which may require a high inclination to explain *** relationships between QPO frequency and QPO rms,hardness,total fractional rms and count rate have also been found in other transient sources,which can indicate that the origin of type-C QPOs is non-thermal.
