论文摘要
在本文中，我们选择了一个样本，其中包括141个最佳时间集成的F光谱和145个最佳峰值通量P光谱，并以已知的红移观察到，以重新检查光谱宽度与$ e_ {iso} $以及$ L_ {ISO} $之间的连接。我们定义了六种绝对光谱宽度。发现所有其余的绝对光谱宽度都与$ e_ {iso} $以及$ l_ {iso} $密切相关，用于F和P光谱。所有的短爆发都是宽度 - $ e_ {iso} $关系的离群值，大多数短爆发与F宽度 - $ L_ {ISO} $关系的长突发一致。此外，所有位置能量，$ e_ {2} $和$ e_ {1} $，对应于各种光谱宽度也与$ e_ {iso} $以及$ l_ {iso} $相关。我们将所有关系与Amati和Yonetoku关系进行比较，并找到宽度 - $ e_ {iso} $和width- $ l_ {iso} $当宽度的宽度约为90 \％\％的最大值$ ef_ {e} $ spectra的最大值几乎与Amati Relation和Yoneteku关系重叠。 $ e_ {2} -e_ {iso} $，$ e_ {1} -e_ {iso} $和$ e_ {2} -l_ {iso} $，$ e_ {iso} $，$ e_ {iso} $，$ e_ {1} -l_ {1} -l_ {iso} $何时在99 \％的$ extime $ extime $ e} $ e} $ e} $ e} $} $ { Yonetoku关系分别。因此，我们确认存在紧密的宽度 - $ e_ {iso} $和width- $ l_ {iso} $长期爆发的关系。我们进一步表明，光谱形状确实与$ e_ {iso} $和$ l_ {iso} $有关。 Amati和Yonetoku关系不一定是将能量与$ e_ {iso} $和$ l_ {iso} $联系起来的最佳关系。它们可能是宽度 - $ e_ {iso} $和width- $ l_ {iso} $关系的特殊情况，或energy- $ e_ {iso} $ and energy- $ l_ {iso} $ resptions。
In this paper, we select a sample including 141 BEST time-integrated F spectra and 145 BEST peak flux P spectra observed by the Konus-Wind with known redshift to recheck the connection between the spectral width and $E_{iso}$ as well as $L_{iso}$. We define six types of absolute spectral widths. It is found that all of the rest-frame absolute spectral widths are strongly positive correlated with $E_{iso}$ as well as $L_{iso}$ for the long burst for both the F and P spectra. All of the short bursts are the outliers for width-$E_{iso}$ relation and most of the short bursts are consistent with the long bursts for the width-$L_{iso}$ relation for both F and P spectra. Moreover, all of the location energy, $E_{2}$ and $E_{1}$, corresponding to various spectral widths are also positive correlated with $E_{iso}$ as well as $L_{iso}$. We compare all of the relations with the Amati and Yonetoku relations and find the width-$E_{iso}$ and width-$L_{iso}$ relations when the widths are at about 90\% maximum of the $EF_{E}$ spectra almost overlap with Amati relation and Yonetoku relation, respectively. The correlations of $E_{2}-E_{iso}$, $E_{1}-E_{iso}$ and $E_{2}-L_{iso}$, $E_{1}-L_{iso}$ when the location energies are at 99\% maximum of the $EF_{E}$ spectra are very close to the Amati and Yonetoku relations, respectively. Therefore, we confirm the existence of tight width-$E_{iso}$ and width-$L_{iso}$ relations for long bursts. We further show that the spectral shape is indeed related to $E_{iso}$ and $L_{iso}$. The Amati and Yonetoku relations are not necessarily the best relationships to relate the energy to the $E_{iso}$ and $L_{iso}$. They may be the special cases of the width-$E_{iso}$ and width-$L_{iso}$ relations or the energy-$E_{iso}$ and energy-$L_{iso}$ relations.
