Under conventional till, crop response to spring soil water content was considerably greater than under zero till.
在常规耕作条件下，春季作物对土壤水份含量的响应要比免耕地大得多。
In summary, under zero till crop response to nitrogen levels in the spring was approximately twice as large compared to conventional till.
总之，在免耕地条件下，春季作物对土壤含氮量的反应大约是常规耕作的2倍。
When Smale reported back to the board in March, he didn't bring good news, as I recounted in Sixty to Zero, published this spring in soft-cover by Yale University Press.
当斯梅尔3月向董事会汇报时，他没带来什么好消息。在今年春季耶鲁大学出版社（Yale University Press）出版的平装新作《60到0》（Sixty to Zero）中，我回顾了这一场景。
This paper deals with the problem of how to skilfully select spring elastic potential energy zero in applying law of conservation of mechanical energy, and makes some analyses combined with examples.
在应用机械能守恒定律时，如何巧选弹簧弹性势能零点问题进行了探讨，并结合实例进行了分析。
If the force P is reduced or made zero, the elastic force will restore the spring to its original unstretched condition.
如果力P减小或变为零，那么弹性力就使弹簧恢复当初的未伸长状态。
If the spring machine after each zero zero position is not accurate, it may be the problem of driving parameters.
若是弹簧机每次归零以后零点位置都不准确，那就可能是驱动参数的问题。
TRUE locking mechanism: The Zero's locking mechanism does not rely on spring tension for security, so entering and exiting Zero pedals is easy, but unintended release is virtually impossible.
真锁定机制：在零的锁定机制不依赖于春季安全压力，所以进入和退出零踏板很容易，但无意发布几乎是不可能的。
Note: The North East will not come too early in spring, the date of floating in the zero to minus six degrees is not faring badly.
东北的春天不会来的太早的，迄今为止浮动在零下六度到零度已是不错。
