作者根据昆明重机股份有限公司的生产实际，深入调查研究，在掌握大量生产应用实际的资料基础上，提出了桥式起重机的箱形主梁的新型波形腹板结构的设想，并在充分比较和论证的基础上提出了以正弦曲线波形作为腹板的波形。 - The character of surface radiation and energy expended over soil temperature variation is that the temperature variation at surface , 5cm depth and 10cm depth are approximately sine curve on clear and cloudy day while this way the temperature variation at 20cm depth shows small extent anti - phase variation and the temperature under 50cm is no diurnal . in contrast , the temperature at 5m , 10cm and 20cm shows linear decrease and the soil - surface temperature is concaved on rainy day
地表辐射和能量耗散反映在土壤温度变化上的特征是晴天和阴天地表、 5cm 、 10cm的温度变化表现为准正玄曲线， 20cm深处的温度变化呈现出幅度很小的反位向变化， 50cm以下地温已不存在日变化特征；雨天5cm 、 10cm和20cm的温度呈线性递减，地表温度表现出由降雨引起的凹陷现象。
