一类扰动迭代函数系生成的分形函数的矩量误差分析

Interfacial shear strengths ( IFSS ) for plasma treated fibers are 3 ~ 4 times as high as that of the control .

经等离子体处理后，超高模量聚乙烯纤维的层间剪切力比未处理纤维高3～4倍。

With further increase of MSA content , treating time and treating temperature , PBO fiber sheath was destroyed , which led to the decrease of IFSS .

当溶液中甲基磺酸的质量分数、处理时间和处理温度进一步提高时，PBO纤维的皮层将遭受破坏，导致界面剪切强度下降。

Since stress singularity was found at the interface end in current specimen of pullout test , interface stress strength ( IFSS ) obtained from the tests loses its rationality .

在单纤维拔出试验中，由于试件的界面端存在应力奇异性，这使试验所得到的界面剪切强度数据失去合理性[1]。

Accordingly , the increase of IFSS indicated that the adhesive performance was improved under short time and low power , however , the IFSS decreased by increasing the treatment time and power .

相应地，IFSS测试的结果表明短时间和低功率的等离子体处理使得复合材料的粘结性能改善了，而长时间和高功率的处理反而使复合材料的粘结性降低了。

Titration analysis , AFM and composites IFSS measurement were used to characterize the acidic functional groups contents on the fibers surface , the surface topography and its composites interfacial shear strength .

通过酸碱滴定法、原子力显微镜表征和复合材料界面剪切强度（IFSS）测试，分析纤维表面酸性官能团含量、表面形貌及其复合材料界面强度的变化规律。

Thirty days after the initial plasma treatment , the smaller water contact angle , higher surface oxygen composition and IFSS to epoxy resin were found for the decane and DMSO pretreated groups .

在等离子处理后30天，这两组纤维有更高的表面氧元素百分含量以及和环氧树脂之间的界面剪切力，同时接触角更小。

It is found that the surface hydrophilicity of PBO fiber is improved and IFSS of PBO fiber / epoxy increases to ( 42 % ) when the fiber was modified by the low temperature plasma .

通过研究发现，经低温氩气等离子处理后，PBO纤维表面亲水性增强，PBO纤维/环氧树脂的IFSS较未处理样品提高了42%。

The interfacial shear strength ( IFSS ) between the Henequen fiber and poly ( hydroxybutyrate-co-valerate ) ( PHBV ) has been improved by the morphological modification of fiber surface .

本文通过对Henequen纤维表面形态进行改性，探讨了提高Henequen纤维与聚羟基丁酸/戊酸酯（PHBV）树脂复合材料界面剪切强度的方法。

The results show that after cold plasma treatment , the increase of oxygen and nitrogen functional groups in the surface improves the surface impregnation of PET fiber and the interfacial shear strength ( IFSS ) property of PET / epoxy composites .

结果表明：经冷等离子体处理PET纤维表面含氧和氮的极性基团增加、浸润性改善显著，进而使涤纶纤维/环氧复合材料界面剪切强度提高。

Combining multi-scale Harris detector with Gaussian-Laplacian detector , the IFSs , which can survive a variety of attacks , are extracted . Besides , the local feature regions are ascertained adaptively based on image local contents and the watermark sequence is embedded into all local feature regions .

算法先利用多尺度Harris算子和Gaussian-Laplacian算子提取IFS，同时结合图像内容自适应地确定局部特征区域，最后采用冗余嵌入策略将水印信息重复地嵌入到所有局部特征区域中。
