查询词典 temperature difference

At present, psychrometric method is widely used to measure the relative humidity in the flue-cured tobacco chamber. The author discovered that when the temperature in the flue-cured tobacco house was higher than 40℃, the relative humidity value obtained by psychrometric method was different from that measured by the criterion instrument. And the difference is greater when the temperature is higher and the relative humidity is lower.

The statistic results showed that: Compared with the earward flow from the midtail, the nearEarth low latitude tailward flow from the ionosphere is characteristic of the lowtemperature and high density; With the tailward flow moving from the lobal region to the plasma sheet, the velocity of the tailward flow decrease, the density and the temperature increase. The tailward flow has distinct anisotropy depending on the difference of the parallel with perpendicular temperature.

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。
