The N fertilizer application under PVC subdrainage suggested that theamount of N fertilizer applied and ratio of bascal fertilizer to topdressing had con-siderable influence on accumulation and distribution of dry matter yield,uptakeand distribution of mineral nutrients such as N.P.K as well as grain yield.

塑料暗管排降条件下长江下游圩区小麦氮肥运筹试验结果表明，氮肥用量及基肥与追肥比例对小麦干物质积累和分配，矿质营养元素吸收和分配，籽粒产量有显著有影响。

Example 30-6 contains an A major chord as VI in C major. Note that this chord does not function as we might expect as V of II. Instead, it fulfills another basic function of the submediant triad: to lead down in 3rd from I to IV. Rising C to C# give emphasis to the chord and intensifies the "Searching" quality of these bars

而他被赋予的是下中三和弦的另一个功能：从I到VI的降3过度作用（书里的意思是说按照由高到低的方式排列I-IV，让VI来作一个过度和弦）把C变为#C给了这个和弦以重点并且加强了这几小节的锐利性和穿透性。
