A calorimeter based on the quasi-steady state theory was developed to measure the latent heat of fusion and specific heat capacity of substance from 250 K to 400 K at atmosphere pressure.
基于准稳态理论,建立了准稳态量热器,可用于常压下250~400 K物质的融解热、固相和液相比热容的实验测量。
To obtain the reason why floccules appear while frozen platelet being thawed,thd authors research several possible related factors.
为找出冰冻血小板融解后出现絮状物的原因,文章对相关的影响因素进行了探讨。
With collected data of the irrigation district in Inner Mogolia,groundwater depth is calculated through slightly amended water balance equation and optimization method after the parameters in the non-freezing-thawing period is ascertained.
根据河套灌区的长期观测资料,确定非冻融期参数后,由稍作修改的水量均衡方程及优化求解方法计算地下水埋深,对冻融期潜水蒸发系数公式逐步进行分析改善,最后在冻结期和融解期采用增加常数项的指数形式的潜水蒸发计算公式,模拟计算的地下水埋深与实际观测结果拟合最好。
