摘  要:
本文聚焦政务微博整体网络,对网络中的整体特性进行剖析.通过引入可达性、聚焦效应、简并度和邻居成员间相互作用4个方面指标,本文从纵向层面对政务微博网络进行了深层剖析,详细地探寻网络中各节点之间的相互作用和网络演化能力.研究表明政务微博具有小世界特性、较高的凝聚力和信息传达性等特征,对政务微博舆情的监管应抓住核心节点,根据各节点不同特征采取相应的运营策略.

摘  要:
The effects of different reducing sulfur concentration on accumulation of dry matter and absorption of IN, P and K in rice were studied by the water culture experiment to explore the poison critical concentration of reducing sulfur against rice. Results: Dry matter accumulation amount decreases by 8. 79%~ 72. 32 % averagely with increase of reducing sulfur concentration compared with CK. The accumulation amount of nitrogen, phosphorus and potassium increases by 5. 31%, 4. 67% and 6. 52% compared with CK respectively when the concentration of reducing sulfur is 50 mg/L, but the accumulation amount of nitrogen, phosphorus and potassium decreases gradually with increase of reducing sulfur concentration. The accumulation amount of dry matter, nitrogen, phosphorus and potassium decreases by 67.43%~72.32% 52.36%~62.49%, 61.39%~63.90% and 61.30%~68.97% compared with CK respectively when the reducing sulfur concentration is 250~300mg/L. In conclusion, the poison critical concentration of reducing sulfur against rice is 250~300mg/L.
