等级不够：rank deficient 意思是not qualified for例句：1. 似乎破产的等级还不够，同样重要的是某些公司持有复杂的金融工具。As if the magnitude of the bankruptcies weren’t enough, there’s also the matter of the complexfinancial instruments that some of the companies held.2. 但同时也存在着固化后交联密度高、质脆、耐温等级不够高和耐冲击性差等缺点。However, the inherent brittleness, limited impact strength and high level of moisture absorption restrict their utility for high-performance applications. 3. 采用线性延伸编码方案显示的彩色等离子体显示器（PDP） ，在消除动态假轮廓方面效果显著，然而在暗场显示时图像灰度等级明显不够。The method of linear stretch out code is effective to remove the dynamic false contour of motion image in color AC PDP, but the gray scale is not enough to display in low level image. 希望被采纳，谢谢！
