planar defect meaning in English

面缺陷

The nanowire is solid and the periphery is very clean without any coating of amorphous material . the - sic nanowires axes lie along the < 111 > direction and possess a high density of planar defects
纳米线是实心的并且表面清晰不带有任何包覆层，其轴线方向是< 111 >方向，并且在纳米线内部有高密度面缺陷。
From the testing result , it is obvious that both the image and location of defects can be accomplished by use of the image device of ultrasonic c - scanning , which is especially effective for testing planar defects
检测结果表明，利用超声c扫描成像装置实现了对sicp al复合材料中缺陷的成像和定位，尤其是对该类材料中的平面型缺陷更为有效，能使缺陷成像清晰，易于判别。
