例句与用法

1. In the summer stratified water column , the deeper the maximum depth of food distribution is , the stronger the dvm is performed ; the increase of the gradient of temperature in the thermocline layer can decrease the magnitude of the dvm and form the thermal barricade to the copepod ; the effects of the predation pressure on dvm is complex . on the one hand , the variations in the distribution depth of the predation pressure vs . the thermocline layer or the depth of the maximum food can modify the dvm patterns of the copepod . on the other hand , different predation pressure induces different dvm patterns
   在夏季分层水体中，食物的最大分布深度越大，动物向下迁移的幅度也越大；温跃层的温度梯度增大可以减小动物迁移的幅度，成为桡足类垂直迁移的温度屏障；捕食压力对垂直迁移的影响较复杂，一方面，捕食压力的分布深度与温跃层或食物峰值的相对位置的变化能够改变桡足类垂直迁移的模式，另一方面，捕食压力强度不同，桡足类垂直迁移的幅度也不同，捕食压力越大，迁移的幅度越大，当捕食压力增加到一定程度，桡足类停止向上的迁移，大部分时间呆在水体深层，可能进入捕食压力引起的“滞育”状态。
2. In the area of seasonal frozen region , the road takes place the cycle of freezing and thawing variety with the season , the mainly disease harm generating from this is the frost heave and frost boiling etc . . . the disease harm belongs to the heat transfer problem , but the effective measure to prevent and cure the frost boiling has something to do with the gradient of temperature and humidity
   在季节性冻土地区,道路随季节交替发生冻融循环变化,由此产生的病害主要是冻胀和翻浆等。病害的形成归根结底属于热质迁移问题,而防治冻胀与翻浆的有效措施无不与温度和湿度有关,搞清冬季冻结过程道路结构体系温度、湿度及应力的状况,是正确设计路基路面,防治冻胀和翻浆的先决条件。
