About tetra-n-butyl ammonium polyiodides: triiodide and pentaiodide anions are the basic building blocks; heptaiodide anion and undecaiodide anion are composed by triiodide anion, and nonaiodide anion is composed by pentaiodide anion. Therefore the character of triiodide, heptaiodide and undecaiodide polyiodides is similar, and that of pentaiodide and nonaiodide polyiodides is similar.

正四丁基多碘化铵化合物中：碘三离子和碘五离子是基本的结构单元，碘七离子和碘十一离子是由碘三离子构成的，碘九离子是由碘五离子构成的，所以碘三、碘七和碘十一形式的高聚碘具有相似的性质，碘五和碘九形式的高聚碘具有相似的性质。

The result showed that there existed spatial variability of soil nutrients. N, P and K had medium variability, which were mainly affected by routine fertilization measures. On the contrary, Organic matter has a smaller spatial variability; Soil nutrient had semi-variance structure, and model best fit included Circular, Pentaspherical and Exponential. There existed medium spatial correlation in N, P, K and OM.

结果表明，土壤养分性质均存在着空间变异性，受常规施肥措施影响较大的碱解氮、速效磷、速效钾变异相对较大；常规施肥有机质投放较少，变异相对较小；土壤养分性质均存在半方差结构，分别拟合Circular、Pentaspherical、Exponential模型，碱解氮、速效磷、速效钾和有机质均显示中等的空间相关性。
