The paper briefly introduces the accurate identification of failures through the correlative and regular computer analysis made by the specialist system on lots of dispersed and isolated data about computer supervision in conjunction with manual experiences and station interlocking relationship so as to provide on-line instructions to swift repair of hidden failures or occurred failures with signal and communication system and reduce the failure rate.
The construction and function of protection circuit and interlock circuit for the thermal engineering after the through-flow capacity of low pressure cylinder of 200 MW unit made in China was introduced , and the interlock relationship among the loops was also discussed, the application effectiveness of its protection and interlock system was presented as well.
An effective solution is brought forward to the safety problems in the station which has hidden safety trouble and can't be rebuilded,that is,modifying the interlocking of signal to ensure the safety of traveling.
It is found in the study that there exists an interlocking relationship among effectiveness, ef ciency, and satisfaction.
It is suspected that there exists an interlocking relationship among effectiveness, ciency, and satisfaction.
These structures, observed in a cross section, have an interlocking relationship to each other.
Underscores landscape architecture theory's interlocking relationship with changing societal constructions of nature, environmentalism, and the city.

It is the first time that a PC(Programrnable Controller )is used to control the signal centralizing and locking system of the mine in China. This paper analyses a few questions in the system and sets up a kind of mathematical model to meet the needs of PC controlling. Based on Boolean matrix this model describes all kinds of locking relationship in the system and it has the advantages of fast computing speed,strict locking and wide compatibility.
This report describes the protection of the reactor, turbine and generator, and the interlock among them. It also presents the conditions, contents, methods and results of the comprehensive inter-lock test. The results of the test is coincident with design requivement.
The status and the prospects of applying PLC in the full cell process and alternating pressure process(APP) were discussed. The inter lock relationship between PLC and the quick opening door was also reviewed.
