Abstract Nuclear vessel hydrostatic test is an important means of sealing and pressure resistance, because the nuclear vessel hydrostatic test involves important system and key equipment, how to optimize the nuclear vessel hydraulic test is a worthy topic. This paper discusses how to optimize nuclear vessel hydrostatic test technology, mainly from three aspects to optimize, such as the optimization of working ticket logic, the optimization of vessel hydrostatic test implementation, and the optimization of hydrostatic test equipment. Optimization of hydrostatic test scheme provides significance reference for plant maintenance.

Testing complex systems on a chip (SoCs) with up to billions of transistors has been a challenge to IC test technology for more than a decade. Most of the research work in IC test technology has focused on problems of production testing, while the problem of self test in the field of application has found much less attention. With SoCs being used also in long-living systems for safety critical applications, such enhanced self test capabilities become essential for the dependability of the host system. For example, automotive electronic systems must be capable of performing a fast and effective start-up self test. For future self-repairing systems, fault diagnosis will become necessary, since it is the base for dedicated system re-configuration. One way to solve this problem is a hierarchical self-test scheme for embedded SoCs, based on hardware and software. The core of the test architecture then is a test processor device, which is optimised to organize and control test functions efficiently and at minimum cost. This device must be highly reliable by itself. The chapter introduces the basic concept of hierarchical HW / SW based self test, the test processor concept and architecture, and its role in a hierarchical self test scheme for SoCs.

Gas drainage is an important means of gas control. The influence of the key position of the sealing hole on gas drainage was studied by theoretical and numerical simulation combined with field measurement to solve low gas concentration in gas predrainage boreholes in coal mines of China. By analyzing the distribution of cracks around the boreholes and the law of air leakage and simulating the drainage effect of different sealing areas (8 m, 12 m, and 16 m), it was proposed that the key position of the sealing hole should be in the prepeak stress concentration area. According to the actual situation of Baode Mine, the sealing test scheme of different sealing areas was put forward, and the field test was carried out to obtain the key sealing area of gas predrainage boreholes in Baode Mine. Research shows that when the sealing area is 8–16 m, the average gas concentration is 63.57%, and the average pure gas flux is 0.408 m3/min. The sealing effect of this area is better, with fewer cracks, than that of the existing sealing area, effectively preventing gas leakage and increasing the gas concentration and gas scalar.

Abstract In recent years, with the popularization of optoelectronic equipment in various industries, various reconnaissance equipment and test equipment have also appeared. Traditional test technology and system functions can no longer meet the development of optoelectronic equipment, so it is imperative to introduce general test ideas and establish a general test system.
