Grounding grid is essential to the safety of substation, however, the corrosion caused by earth may result in thinness even break of the grounding down-lead and horizontal equal-voltage conductor. This will lead to fault spread when grounding fault occurs, and will be dangerous to human and facilities.

接地网对变电站安全运行至关重要，但土壤的腐蚀可能使接地引线和水平均压导体变细甚至断裂，当系统发生接地故障时可能造成事故扩大，危及设备和人身安全。

The saving-water effect of Radish and Cabbage under PFM and appropriate irrigation,and the drought-resisting of radish seedling which seed was soaked by CaCl_2 were systematicly reseached by field observation and the experiment in door.The main results were summaried as follows:The soil temperature of 0~20cm cultivated layer was increased 3-4.5℃ in early growth period was only 1℃ in late growth period by PFM;there was more water saved up to 20.84mm in 0~60cm soil layer by PFM than no PFM in the early growth period of Radish;the yield and water use efficiency of Radish in L4 were exceeded respectively 10.1% and 21.9% of that contrast, the yield and water use efficiency of Cabbage in G4 were exceeded respectively 8.7% and 26.58% of that contrast, under PFM and appropriate irrigation.

主要研究结果如下：地膜覆盖在植株生长前期耕作层平均可增温3～4.5℃，在生长后期增温幅度减小，仅有1℃左右；地膜覆盖在植株生长前期可有效的保持土壤水分，在萝卜生长前期，使0～60cm土层内多储水20.84mm；在覆膜不灌水充分利用自然降雨的条件下生产萝卜，可比裸地正常灌水萝卜增产10.1%，水分利用效率提高21.9%；覆膜只浇一水生产甘蓝，可比裸地正常灌水生产甘蓝增产8.7%，水分利用效率提高26.58%。

The algorithm is robust to clock asynchrony of nodes in different clusters, hence it is applicable to large-scale sensor networks, for which precise time synchronization is very hard.

仿真实验表明，提出的这种算法能使各个组内的传感器节点较为均匀地分布在目标区域，获得的平均覆盖率接近于上界值。

In this paper, original codebooks are designed with the greedy tree growing algorithm instead of the splitting algorithm, and PSNR is improved by 0.6db in average.
