避免选取重根，根据根轨迹(root locus)法则，在重根那一点的根灵敏度(root sensitivity)为无穷大，k 值只要有一点小变动，取得的根就可能有很大的差别， 何况经由计算出来的结果，必定经过四舍五入的进位，含有一定量的...

root dentine sensitivity 易发生牙本质敏感症
Through regression assaying, the root length and shoot length EC50 were made out respectively, and then compared the sensitivity of 2 grasses seedling to 30 pesticides.
通过回归分析求出不同农药对2种草坪草根长与茎长的EC50值；并把30种农药对2种草坪草的敏感性进行比较。
The families with great P efficiency have great height growth rate, high productivity and extensive lateral root system under low phosphorus stress and low sensitivity to phosphorus supply.
磷效率高的家系具有在低磷胁迫下苗高生长量大、干物质积累能力强、须侧根发达及对磷肥投入敏感性低等特点。
The results indicated that the sensitivity is appoximately proportional to the square root of the length of grating. And so does the result derived from Fourier analysis and spatial-frequency channel.
从空间频率通道的观点出发，也可推导出对比灵敏度是和条纹长度的平方根成正比。
