本发明涉及一种时频资源的分配方法，所述方法包括：把一个长度为L的序列{x，i＝0，1，2，…L-1}中的每一点作为一个k次多项式的自变量，改变多项式的系数生成多个长度为L的序列{f}，其中k是非负整数，多项式中的运算在伽罗华域GF中进行，其中Q＝p m ，p是一个素数，m是非负整数；把生成的序列分配给多个小区，生成各小区的偏置序列集合，其中分配给同一个小区的序列所对应的生成多项式的常数项不同，其他项的系数都相同；由所述小区的偏置序列生成对应的时频图案单元，将时频图案单元经过频域等间隔重复，得到完整的时频图案。

The total RNA was extracted from spleen of Xiphophorus helleri which had been immunized for two weeks. The core sequence was amplified by RT-PCR. The cDNA end sequences were amplified by RACE, and then the full-length cDNA of sIgM heavy chains gene were obtained by putting all of them. The full-length sequence contains the immunoglobulin signature sequence: FKCIANH.

The results indicated that organic fertilizer at a rate of 75000 kg/ha or organic fertilizer (75000 kg/ha) with compound fertilizer at a rate of 300 kg/ha had higher effects on genetic diversity of soil microbial community under field conditions. Treatment of fertilizers as base application at level of 600 kg/ha resulted in decrease of DNA sequence richness index and diversity index of soil microbial communities, and the similarity coefficient of DNA sequence from soil microbial communities was the lowest compared with control. Organic fertilizer treatment was conducive to increasing DNA sequence diversity index and evenness index of soil microbial communities.

结果表明，在本试验条件下，基肥为75000kg/hm^2有机肥处理和75000kg/hm^2有机肥加300kg/hm^2复合肥处理最好；基肥为600kg/hm^2复合肥处理使土壤微生物群落DNA序列丰富度指数和多样性指数显著下降，与对照的DNA序列相似系数最低；有机肥处理有利于土壤微生物群落DNA序列多样性、均匀度和黄瓜产量的提高。

The results showed:intercomparison sequence from Exonl to part Intronl fragment amplification by primers 1 of two individual selection from each swinery with pig L-FABP gene sequence published in GenBank,found that base site of 237、258、315 of all individuals were A、T and A respectively,different with DQ182323 base sequence of G、C and C,and existence G403A mutation between individual.

结果表明：引物1扩增的外显子1到部分内含子1片段每个猪群选择两个个体经测序得到的序列与GenBank上已发表的猪(DQ182323)的L-FABP基因序列比对，发现所测所有个体237位点、258位点和315位点碱基分别为A、T和T与DQ182323序列的碱基G、C和C不同，而且所测个体间存在G403A突变。

By using the techniques of an explicit criterion to determine the number of real roots of a univariate polynomial in ( [13] , [73] ); B-net form of bivariate splines function; discriminant sequence of polynomial (cf. [13] , [73] ) and the number of sign changes in the sequence of coefficients of the highest degree terms of sturm sequence, this paper determines the number of real intersection points two piecewise algebraic curves whose common points are finite.

Two gene fragments of DEN-1(GenBank accession number DQ886390)and DEN-2(GenBank accession number DQ886391),differentially expressed between the ocular skin tissues of normal and albino turbot,were isolated by mRNA differential display and sequenced.It was confirmed by RT-PCR method that the expression levels of both DEN-1 and DEN-2 were down-regulated in the ocular skin tissue of albino turbot.The sequence homology search of DEN-1 revealed high sequence homologies with the UGGT genes of zebrafish and cattle,and the Ugcgl1 gene of Norway rat.High sequence homologies of DEN-2 were observed with the eya4 gene(the eye absent homolog 4)from red jungle fowl,zebrafish,human,Norway rat,mouse and dog.
