查询词典 randomization test

Methods:1297 students of primary and middle school were randomly investigated with test anxiety test before graduating examination.results: the higher the grade , the higher the score of tat; the prevalence rate of test anxiety is higher in boy students than girl students and the level of test anxiety in boy students was increasing with grade.conclusions: the prevalence rate of test anxiety is common in the students of primary and middle school before graduating examination .it is necessary to give mental intervention.

对随机抽取的小学、初中、高中毕业班的学生进行考试焦虑测验表问卷调查。结果：随着年级的增加其tat分值也显示出增加；在性别比的构成上则显示出男生的焦虑水平随着年级的增高而增加；男生中、重度考试焦虑的发生率高于女生。结论：考试焦虑的发生率在中考和高考的学生中较为普遍，应予以重视。

Results indicated that the variation was significant from treatment to treatment. S-deficiency caused bulging chloroplasts, loosening and dishevelled grana lamella, reducing organelle, and damaged chondriosome in mesophyll cells of the leaves, and empty cells of the roots, while S-excess, however, led to densification, condensation and randomization of grana lamella of the chloroplasts of the leaves, and separation of cytoplasms from walls of the cells of the roots.

结果表明，受S素营养胁迫的水稻，其根系及叶片的超微结构均发生了显著的变化：低S胁迫会造成水稻叶片叶肉细胞内的叶绿体结构肿胀，基粒片层松驰、散乱，细胞器减少，线粒体结构被破坏，根系细胞内几乎没有内含物；S浓度高则会使叶片叶绿体基粒片层致密、浓缩，无规则化，根系细胞发生质壁分离。

From an angle of engineering application, this paper dealt with the wavelet packets decomposition principle and its energy spectrum monitoring theory, which were used to extract the features of drilling force signals. Meanwhile, with an aim at the strong randomization and uncertainty characteristics between the feature vectors and drill wears in drilling process, a kind of drill wear monitoring method based on Hidden Markov Model was presented.
