It was suggested that machining deduction must be considered in head plate design through the analysis of standards GB150-1998 and JB/T4746-2002.The maximum of the design thickness and the nominal thickness minus machining deduction must be taken as the minimum forming thickness of head plate.
According to the prescript of the law and code, we give a systematic survey about the least quality control development direction of specialization production requests on head plate manufacture of pressure vessel, so as to improve the whole quality of pressure vessel products and ensure the safety of special equipments.
Qualification licence and forcible supervision inspection regulations were enforced by the law and code of China for the first time on head plate manufacture of special equipments such as pressure vessels etc.
EGFR is over-expressed in numerous tumors including, those derived from the brain, lung, bladder, head and neck.
It is found that the head-on face (in contact with solution) of the films is green while the back face is white.
Optimal approximation of head-related transfer function's pole-zero model based on genetic algorithm
In the research on spatial hearing and virtual auditory space, it is important to effectively model the head-related transfer functions (HRTFs).
In the research on spatial hearing and realization of virtual auditory space, it is important to effectively model the head-related transfer functions (HRTFs) or head-related impulse responses (HRIRs).
A bottoms port, as well as ports in the reactor's head plate, facilitated sampling of the slurry and measuring the pH, which changes from an initial value of 5 before cooking to a value of approx 3 after cooking.
Ports in the reactor's head plate facilitated sampling of the slurry and monitoring the pH.
The labeling was also observed on the cuticular plate of the hair cells, the head and cone of the pillar cells and the head plate of Deiters' cells and other supporting cells.
A frame on the head plate with arrows indicates the point at which the measurement should be read.
The arrow in D points to a bleb from the inner pillar cell head plate that impinged on the IHC stereocilia tuft.
