SSR markers are useful in pepper linkage mapping and gene location. 446 SSR markers have been reported, but they are insufficient. It is costly to develop SSR markers from DNA library, whereas it seems much easy to find in EST sequences in the GenBank of pepper through internet. In this study, attempts have been made to develop SSR markers in the EST sequences by using bioinformatics. EST sequences were trimmed by ‘***’ software, while 116 915 EST sequences were obtained without poly ‘A’ or poly ‘T’, ranged between 100 and 700 bp. Using ‘e-PCR’ and ‘***’ softwares, SSR sequences were identified. 2 508 microsatellite loci （larger than 20 repeats） were established and 755 SSR primers were designed using SSR finder software and Primer 3 software. There were 498 （0.43%） mono-, 1 026 （0.89%） di-, 518 （0.45%） tri-, 245 （0.21%） tetra-, 114 （0.10%） penta-, and 107 （0.09%） hexa-nucleotide SSRs. The estimated frequency of SSRs was approximately 1/25.12 kb. According to the distribution of SSRs in pepper, the mean length of pepper SSRs was 22.68 bp and the adenine rich repeats such as A/T, AG, AT, AAG, AAAT, and AAAC were predominant in each type of SSRs （mono-, di-, tri-, tetra-, penta-, and hexa-）, whereas the C/G, CG, CCG repeats were less abundant. 210 primers were tested in 8 pepper cultivars and the PCR result revealed the existence of polymorphism among 127 （60.48%） SSR primers within 8 pepper cultivars. It is confirmed that pepper EST database could be efficiently exploited for availability of SSR markers.

为准确估测复合种植方式下大豆和玉米的株高,分别利用均值插值法和线性插值法生成的数字地面模型(Digital terrain model,DTM)和基于无人机影像生成的数字表面模型(Digital surface model,DSM)进行处理,得到复合种植方式下大豆和玉米的冠层高度模型(Canopy height model,CHM)。借助线性回归方法并结合决定系数(R^(2))和均方根误差(RMSE)对模型进行精度分析,筛选出精度更高的株高模型对应的插值方法,并采用该模型实现对复合种植方式下大豆和玉米株高的动态反演。结果表明,线性插值得到的DTM经过处理最后生成的CHM估测效果更好,模型的R^(2)为0.85,RMSE为7.05 cm。表明在缺少完整DTM数据的情况下,借助插值生成的小面积DTM与基于无人机影像生成的DSM构建冠层高度模型,并实现复合种植方式下大豆和玉米株高动态反演的方法可行。

A series of random terpolymers P2-P5 were designed and synthesized by randomly embedding 5 mol%, 10 mol%, 15 mol% and 25 mol% feed ratios of low cost 2,2-bithiophene as the third monomer to the famous donor-acceptor （D-A） type copolymer PTBT-Th （P1）. All polymers showed similar molecular weight with number-average molecular weight （Mn） and weight-average molecular weight （Mw） in the range of （59-74） and （93-114） kg·mol-1, respectively, to ensure a fair comparison on the structure-property relationships. Compared with the control copolymer PTBT-Th, the random terpolymers exhibited enhanced absorption intensity in a wide range from 400 nm to 650 nm in both solution and film as well as in polymer/PC71BM blends. From grazing incident wide-angle X-ray diffraction （GIWAXS）, compared with the regularly alternated copolymer PTB7-Th, the random terpolymers demonstrated mild structural disorder with reduced （100） lamellar stacking and slightly weakened （010） π-π stacking for the polymers as well as slightly reduced PC71BM aggregation in polymer/PC71BM blends. However, the measured hole mobility for terpolymers （（1.20-3.73） × 10 -4 cm2·V-1·s-1） was evaluated to be comparable or even higher than 1.35 × 10 -4 cm2·V-1 ·s-1 of the alternative copolymer. Enhanced average power conversion efficiency （PCE） from 7.35% to 8.11% and 7.79% to 8.37% was observed in both conventional and inverted device architectures from copolymer P1 to terpolymers P4, while further increasing the 2,2-bithiophene feed ratio decreased the PCE.
