在焊缝断带研究中，经过因子试验，发现反射率和填充两个因子都对焊缝有显著影响，又进行一轮二因子全因子试验（22+3）：反射率取150（-）、340（+）；填充取15（-）18（+）。对试验结果的分析中发现回归方程的弯曲很严重，下一步必须进行响应曲面试验。由于经费困难，希望试验次数尽可能地少，而试验条件上的反射率又不可能超过340。希望能在归纳出二阶回归方程的条件下尽量减少试验次数，这时可行的最好的方法是（）

A.采用CCC（中心复合序贯设计），只再增加4个星号点（轴向点）试验

B.采用CCI（中心复合有界设计），只再增加4个星号点（轴向点）试验

C.采用CCF（中心复合表面设计），只再增加4个星号点（轴向点）试验

D.采用CCF（中心复合表面设计），除再增加4个星号点（轴向点）试验外，还要再加3个中心点试验
