The deposition method comprises the following steps: 1) heating metal substrate; carrying out deposition. The method is characterized in the step 1) that a current is conducted into the metal substrate at one end of the growth zone by one electrode, and out of the metal substrate at the other end of the growth zone by the other electrode, so that the metal substrate is heated by the heat emitting of the resistant of the metal substrate itself. According to the method, the quality of the prepared thin film is improved, while the preparation cost of the thin film is reduced. In addition, the consistent double-sided thin films can be easily prepared on two surfaces of the metal substrate by employing the system and method.

Abstract: The present invention discloses a simulation signal viewing method and system for a digital product. Firstly, a controller controls a FPGA to perform a first simulation verification by reading and recording status data of all external ports of the digital product in real time, and reading and recording all internal status data of the digital product once at each interval. After the simulation is completed, if data of a certain clock cycle of the digital product needs to be viewed in a backtracking manner, the controller reads the internal status data of the digital product stored at a last time point before the certain clock cycle and the status data of the external ports at the last time point, and, using the read data as initial operating status data for a second simulation verification, starts the FPGA to operate to one clock cycle before the certain clock cycle.

Abstract: The present invention discloses a method and system for viewing simulation signals of a digital product. When a controller controls a FPGA to perform a first simulation verification, the controller reads and records status data of all external ports of the digital product in real time, and reads and records all internal status data of the digital product once at each interval. After the FPGA simulation is completed, if data of a certain clock cycle of the digital product needs to be viewed in a backtracking manner, the controller loads the digital product into the software simulator to perform a second simulation verification, and sets the external port status data and the internal status data recorded at said last time point as an initial status of the digital product. By adopting the technical solution, all simulated data of any clock cycle can be viewed quickly in a backtracking manner.

Abstract: A testing apparatus for determining tensile strength of soft rock and soil tests a sample having a central hole. A drawbar device holds the sample in a central, upright position. The drawbar device has two main parts, namely the left fixed part and the right lateral movable part. A fixed frame connects to the left fixed part and a lateral movable frame connects to the right lateral movable part. The drawbar device has two arms. The sample is positioned on the central pull rod through the hole of the sample. A tension sensor and a displacement sensor detect the tension force and displacement as the sample is pulled apart. A data analysis module calculates a tensile strength based on the tension force and the displacement by the equation: ?t=500 ?Fmax/(R?r)h.
