low temperature tolerance

The existing dispersants cannot meet the cementing requirements of deep and ultra-deep wells, having low temperature tolerance, low brine resistance, retarding, bubbling, and some other problems.

现有分散剂存在抗温耐盐性能不能满足深井、超深井固井要求，有缓凝或起气泡副作用等问题。

Summer heat can often exacerbate tension -as the temperature rises, so do many tempers, while patience and tolerance seem to drop to low levels.

夏季炎热可以加剧紧张情绪——当温度升高时，脾气也升高了，而耐心和容忍度却降到了较低的水平。

Many plants can acquire increased frost tolerance after a period of exposure to low, non-freezing temperature through a complex adaptive process called cold acclimation.

许多植物在经过一段时间的非冻低温作用后其抗寒性获得增强，这种现象被称为植物的低温驯化。
