Random vibration test of the commodity and the equipment in the laboratory have the very big economical significance.
在实验室内对车载物资和装备进行随机振动试验具有很大的经济意义,目前国际上普遍采用的一种试验方法是在频域内再现功率谱密度和随机波形,而功率谱密度通常是由实测振动数据经过自功率谱密度函数分析后得到。

催产素激惹试验
又称宫缩应激试验。其原理是人为的制造宫缩环境，如用催产素诱导宫缩约每10分钟3次，利用胎儿监护仪记录胎心率在宫缩前后的变化。正常情况下，子宫收缩时胎盘血液循环暂时阻断，故胎心会有改变，但宫缩停止后胎心会很快恢复。若子宫收缩开始后一段时间(多在高峰后)发现胎心率减慢，下降得慢，下降幅度小于50bpm(每分钟胎心次数)。持续时间长，恢复亦缓慢，称为晚期减速。如果宫缩后多次出现晚期减速为OCT阳性，示胎儿子宫内缺氧，应立即终止妊娠。若无宫缩后晚期减速。为OCT阴性。示胎盘功能佳，胎儿宫内情况良好。
