The results show that, under each drip irrigation treatment before the tasselling stage of spring maize, the fluctuation of average soil water content and soil matric potential at different soil depthes are comparative low under high frequency drip irrigation treatment, and the HDI can hold stable soil water content. The drip irrigation can obviously delay the effect of air temperature on the soil temperature, which was influenced by irrigation process, soil water content and crop growth stages. In addition, the irrigation frequency affects the spring maize root distribution in the soil, and the HDI improves the probability of root distribution in upper soil(0~40 cm). The yield difference of spring maize for irrigation frequency treatments is not significant under the typical field irrigation model combined irrigation with precipitation.

试验结果表明：在春玉米抽雄期以前阶段实施的滴灌各处理中，高频滴灌下土壤平均含水率和不同深度处的土壤基质势波动幅度较小，高频滴灌下土壤水分能保持在一个比较稳定的范围；土壤温度受灌水过程、土壤含水率及作物生育阶段的影响较明显，滴灌能显著延迟气温对土壤温度的影响；灌水频率对春玉米根系分布存在一定影响，高频灌溉能显著促进春玉米根系在上层土壤(0～40 cm)中的分布；此外，在这种典型的灌溉和降雨相结合灌溉模式下，不同灌水频率下玉米产量差异不显著。

Among the slope instability types, thaw slumping is the most hazardous to engineering projects. The ground temperature data of long-term monitoring in the typical thaw slumping indicates that average ground temperature increases and annual fluctuation of ground temperature are reducing under the thaw slumping. The reason is that the heat flux entering permafrost reduces.

针对典型热融滑塌进行的温度监测资料表明，在滑塌的影响下，其下多年冻土地温年变化幅度趋小而年平均地温升高，导致产生这一现象的原因在于每年进入多年冻土的冷能有所降低。

The presence of these resonance of phosphorus in at least two types of phosphorus environments. The spectra of nanorod contained typical bands of hexahedra Ca(superscript 2+)at 200 nm. The Eg values for the HA of microcrystalline, nanorod samples were 1.60 and 1.64ev, respectively. The FTIR spectra of the nanorods include two types of vibration; three PO4(superscript 3-) stretching modes at 956.5, 1 026.1 and 1 108.7cm^(-1) band were attributed to the vi (PO4), v3 (PO4), v3 (PO4) modes respectively.

结果 HA纳米粒的平均尺寸为。10~30nm；共振分析表明，磷至少以2种类型存在；在200nm波长处，光谱包含六面体Ca(上标 2+)典型的光谱带；HA纳米粒微晶的Eg值分别为1.60和1.64ev；傅里叶变换红外光谱中包含2种振波；在956.5、1026.1和1 108.7cm光带处的3种PO4(上标 3-)曲态分别为v1(PO4)、v3(PO4)、v3(PO4)。
