According to the research of existing triaxial testing machine of deep rock, a new test chamber with temperature-hold and pressure-tight is developed.The features of test box are as follows: a new kind of axial displacement test system with outer embedded type is designed for measuring the axial displacement of samples correctly; the circuit of oiling system is used to keep temperature and pressure; it’s convenient to take down the test box from the machine and the other functions of testing machine are not affected. So the availability factor of instrument can be improved. Finally, the thickness of cylinder wall is calculated, and according to the modeling and finite element analysis based on ANSYS, the results show that the cylinder can meet the working requirement.

This research is motivated by the lack of critical thinking skills and the ability to think creatively mathematical mathematical students. This study reviews, Upgrades Critical Thinking Mathematical and Thinking Skills Creative Mathematical and differences between students who apply Learning Strategies Relating, Experiencing, Applying, Cooperating, and Transferring (REACT) with students who received conventional learning models, and relationships critical thinking skills and mathematical creative thinking ability of students. The method used in this study is a mixed methods embedded type. The study population were students of class X SMK Pasundan I Cianjur enrolled in the academic year 2015/2016. The samples used were two classes of 14 existing classes. The instrument used to collect data in the form of instrument test critical thinking skills and the ability to think creatively mathematically, attitude scale, observation and interview sheet. Data were analyzed using mean difference test ie t-test (quantitative) and descriptions (qualitative). The results showed that Improvement of critical thinking skills of students who apply strategies Learning Relating, Experiencing, Applying, Cooperating, and Transferring (REACT) better than students who use learning models conventional.
