研究人员计算出在记忆测试里她们每超过一个身体质量系数（BMI——身高kg/体重m的平方）值，她们的记忆力就下降一个单位。

The researchers calculated that every extra point of body mass index (BMI – your weight in kilograms divided by the square of your height in metres) led to a 1-point drop in the memory test.

同时，分析了桩身驰豫时间、桩侧土的等效粘滞阻尼系数、桩底土的单位刚度等因素对应力波的影响。

The study also goes to the influence, upon stress waves, of the piles relaxation time, the equivalent viscous damping coefficient of soil around the pile and the unit rigidity of soil below the pile.

另外，还获得了一些重要的系统性能参数，如季节供冷系数、单位埋深取冷率。

Moreover, some important system performance parameters were obtained, such as the cooling seasonal performance factor and the cold extraction rate per unit depth of borehole.
