The ultrasonic testing method was used commonly. because of the material properties of concrete, internal interface complex of concrete material, it is not easy to quantitative analysis uncompacted area, hollow and crack size.
Ant Colony algorithm application in inspection of defects 3.1 Selection of eigenvector of ultrasonic signal For the defective materials, defect position, size, shape and other properties difference makes the reflection echo contains various frequency components.

Comprehensive evaluation can determine whether students learning course materials required, both of online quizzes and class exams can achieve different purposes.
The online quizzes materials are sent to students by teachers, which should be finished by students in proper time.

Testing dimension: 20mm×20mm, depth of engrave: 3.5mm, depth of cut: 0.5 mm, cutting tool model: conic tool 90°-0.2. 2 Choice of engraving function for curved surface (1) Choosing the curved surface to be cut All types of curved surface can be engraved including art grid curved surface, science of geometry surface input through data transformed interface.
(3)Cutting tool setting for rough engraving Rough engraving is used to remove excess material and obtain the approximately outlook fast.
The choice of cutter type should consider compositely material and complexity of curved surface.
Considering tool strength and abrasion resistance, big diameter cutter is used for machining hard materials, see the reference illustration of Fig.3

Basic curriculum design and teaching conditions indicators, including teaching files, two indicators of the material conditions of two main test of the adequacy of teaching documents, laboratory equipment and venues can meet the requirements of the curriculum design teaching.
Analog electronics course design quality control standards:1) Debug and analysis the material, whether to meet the requirements;2) The content and format of the paper determine the paper is up to standard.
Pre-design, students can receive the required components and other materials to the laboratory by the instructor review by the circuit and the test box or test board assembly.
Debugging problems, and explain the measures to solve; test, record, collate and results analysis; 6) The experience, problems and further improvements; Grading After the end of the course design, teachers will be based on the following aspects to be assessed: 1) The correctness and rationality of the design. 2) Practical ability (to install the technology level, debugging, analysis of problem-solving skills, as well as the spirit of innovation, etc.). 3) Summary report. 4) The respondent (subject of discourse, and answer questions). 5) The design process of learning attitude, work style and spirit of science.

， (4) For rock materials obeying associated flow rule, the plastic strain increment is: (5) Where is yield function, assuming that rock materials complies with Mohr-Coulomb criterion, the yield function in the sliding surface is: (6) Equation (5) is substituted by Equation (6), we can get (7) Equation (7) shows that if the sliding surface complies with Mohr-Coulomb criterion and associated plastic flow rule, the angle between the direction of plastic deformation increment and normal direction of sliding surface is (See Fig.2).

When building finite element analysis model, the authors make the following hypothesis: ①after electrodes contact with lithium-ion battery poles, there is no longer any relative motion; ② the driving force F2’ equably exerts on the contact surface where the head of electrode clamps connected with driving boards. ③the material of electrode clamps are isotropic.
A couple of clamp deformation figure and its stress distributing graph As is shown in Fig 5, when Δs is 0.5mm, the electrodes grip the poles, the maximal stress occurs on point A, the value is 169.49Mpa, while the yield strength of 55Si2MnB is 1176 Mpa, the maximal stress is much smaller than the yield strength of the material.
