By analyzing the test method named orthogonal 12 points for accelerometer, there are several problems to be solved in the temperature experiments for accelerometer. In order to study the temperature characteristics of the accelerometer for better, the testing system for accelerometer based on Labview is designed and the composition of the system is introduced. The microprocessor used in the temperature experiment is C8052F series microcontrollers. A 24-bit A/D converter is embedded in the microprocessor and the resolution of 0.149 microvolts can meet the accuracy requirements of the accelerometer. According to the requirements of high accuracy and test efficiency for accelerometer, the digital multi-channel testing technology is applied to realize the accurate test. The application in temperature experiments indicates that this precise and steady testing system can meet the requirement of accelerometer calibrating & testing completely.

We present the open-source AiZynthFinder software that can be readily used in retrosynthetic planning. The algorithm is based on a Monte Carlo tree search that recursively breaks down a molecule to purchasable precursors. The tree search is guided by an artificial neural network policy that suggests possible precursors by utilizing a library of known reaction templates. The software is fast and can typically find a solution in less than 10 seconds and perform a complete search in less than 1 minute. Moreover, the writing of the code was guided by a range of software engineering principles such as automatic testing, system design and continuous integration leading to robust software. The object-oriented design makes the software very flexible and can straightforwardly be extended to support a range of new features. Finally, the software is clearly documented and should be easy to get started with. The software is available at http://www.github.com/MolecularAI/aizynthfinder.
