This study applied the Porter’s alignment model to construct a localized two-dimensional framework based on Anderson's taxonomy. The research chose the third-grade primary school science textbooks from two representative presses in China and Japan, coded the textbooks and curriculum standards, calculated the alignment level between the textbooks of the two presses and their corresponding curriculum standards, and discussed the alignment level from the topic, cognitive demand, and emphasis. The results show that the B version in Japan is significantly aligned with the Japanese curriculum standard, but the A version in China does not have significant alignment with the Chinese curriculum standard. Besides, a common problem is that the ratios of life science in sample science textbooks both exceed the requirements of the curriculum standards, and the problems of exceeding the standard in cognitive demand and not highlighting the key points also need to be concerned. This study provides ideas and references for countries with similar educational situations to study the compilation of science textbooks and fills up the deficiency of the international comparison of the alignment between primary school science textbooks and curriculum standards by using the alignment model. Keywords: alignment evaluation, content analysis, curriculum standards, primary school, science textbooks

The support reaction plays an important role to the shell stresses of rotary kiln, which is greatly affected by the kiln axis defection. The displacement measurement method along zero deformation direction is introduced, which can be used to monitor the defection of rotating center of kiln shell at the support pier exactly. The mechanical model to solve the support reactions is built based on the mechanical feature analysis of rotary kiln, and a fast solution to the support reactions is formed, the correlation between the support reactions and the axis defection can be obtained quickly by the method.

This paper analyzed the kinematical and mechanical feature of the trip operation for the 03A driller based on the dynamic brake theory of AC variable frequency motor. The moving pattern of the strip operation and the variable information of the load in winch roller were mastered. We checked the safety coefficient of the winch brake and put forward the suggestions on the safe operation for AC variable frequency controlled driller. This paper is very important for promoting the application of AC frequency technology in drillers.

Typical examples of four different speech disorders—voice, cleft palate, articulation, and stuttering—were ranked for severity by kindergarten, first-grade, second-grade, and third-grade teachers and by public school speech clinicians. Results indicated that classroom teachers, as a group, moderately agreed with speech clinicians regarding the severity of different speech disorders, and classroom teachers displayed significantly more agreement among themselves than did the speech clinicians.
