1) vertical vibration characteristic
垂向振动特征
2) vertical vibration
垂向振动
1.
When current of water passes the plane gate, the flow shape is destroyed by the bottom edge of gate and leads to the vertical vibration.
分析认为当闸下过流时,水流受到闸门底缘的影响产生空蚀并诱发闸门的垂向振动,单一的垂向振动虽不会危及闸门安全,但却能破坏下游泄水道内的漩涡区,加大闸门下游水流的扰动外力。

补充资料：垂丝海棠的形态特征
垂丝海棠又名锦带花，属蔷薇科，苹果属，为落叶灌木或小乔木。原产我国华东、中南、西南，以四川为最多。此花树姿婆婆，花粉红色，花梗细长，紫红色，下垂成带状，花4-7朵聚生为一簇，形似樱花，花瓣5枚以上，朵朵弯垂，迎风轻荡，色艳韵美，绰约动人。常见的垂丝海棠有两种，一为重瓣垂丝海棠，花为重瓣；一为白花垂丝海棠，花近白色，小而梗短。垂丝海棠性喜阳光，不耐阴，也不甚耐寒，爱温暖湿润环境，适生于阳光充足、背风之处，土壤要求不严，微酸或微碱性土壤均可成长，但以土层深厚、疏松、肥沃、排水良好略带粘质的生长更好。此花生性强健，栽培容易，不需要特殊技术管理，唯不耐水涝，盆栽须防止水渍，以免烂根。
