It is firstly found that the NOx concentration increases rapidly when is less than 0.75, which complements the staged combustion and the rich-lean combustion that are well considered currently as low NOx combustion. It does not mean that the combustion must be the low NOx combustion when . There is a limited least value of air excess coefficient. The combustion is not the low NOx combustion when is less than the limited least value.

In a method for retrieving sequences having a minimum PAPR in an OFDM (orthogonal frequency division multiplexing) system, by using characteristics in which all sequences of the OFDM system are classified into cosets having the same PAPR, PAPRs of sequences in which early two elements are fixed as '0' are calculated. A sequence having a minimum PAPR is selected from among the calculated PAPRs, and sequences allocated to the coset in which the selected sequence is included are retrieved as sequences having the minimum PAPR.

在一种用于在OFDM通信系统中恢复具有最低PAPR的序列的方法中，通过利用在其中将OFDM系统的所有序列分成具有相同PAPR的同余类序列的特性，计算两个开始项被固定为"0"的序列的PAPR，在所计算的PAPR中选择具有最小PAPR的序列，并且恢复分配至在其中包含所选同余类序列的序列作为具有最小PAPR的序列。
