It is also necessary that the center value of load capacitance (to determine the absolute value of oscillation frequency) and the variable range (fine adjustment range of oscillation frequency) are maintained at the optimum values in the oscillation circuit.

在振荡电路中，负载电容的中心值(其决定谐振频率的绝对值)和其变化范围(谐振频率的良好调整范围)应保持在最佳值。

Contrasting with control treatment, the fit of the Exponential distribution in characterizing fine root longevity was elevated under N amendment treatment, at the same time, the distributions of Welibull, Lognormal, and Normal were still better in character. All above indicated that N fertilization treatment maybe only alter the absolute value of longevity frequency, but the ratio between longevity frequencies was the same as before. So the model of longevity was unalterable.(5) Regardless analyzed with whichever categories i.e.

对各生长季细根寿命的统计分布拟合检验的结果与对照相似，施肥仅仅提高了总体分布对细根寿命的拟合优度，但威布尔、正态以及对数正态分布仍然拟合最好，这说明施肥可能仅改变了不同细根寿命频数的绝对值，但各寿命频数间相对比例并未发生明显变化，寿命理论分布的类型保持不变。
