Simulation results prove that symmetry algorithm is applicable for generating the long periodic hopping pattern used in valid data communications, while random shift replace algorithm is proper for the short periodic pattern with the good balance in the range of maximum effective length, and it can be used in the situations of short-cycle emergency communications.

仿真结果表明，对偶法在长周期条件下的性能优于随机平移法，适用于产生正常通信使用的调制跳变图案；随机平移法在最大有效周期长度范围内具有很好的均衡性，适用于短周期突发通信。

The root hair morphology of cv. RM109 was observed and compared. The results indicated that in the distance of 1 cm to the apical of seed root, the number of root hair of RM109 was 19% of cv. Oochikara, and the root diameters were not different from cv. Oochikara; in the distance of 8 cm, the number of root hair and the root diameters of RM109 were 45% and 79% of cv. Oochikara, in the distance of 3 cm, the length of the longest root hair was 33% of cv. Oochikara; but the length from the apical of the seed root to root hair initiation was not different.

根毛观察比较显示，距种子根根端1 cm处的RM109根毛数是&大力&品种的19%，差异极显著，根直径与&大力&品种差异不显著；距根端8 cm处的RM109根毛数和根直径分别是&大力&品种的45%和79%，二者差异极显著；距根端3 cm处，RM109最大根毛长是&大力&品种的33%，差异极显著；RM109种子根根端到根毛发生区的长度，与&大力&品种的差异不显著。
