The article presents a series of practical approaches to hydraulic computation of condensate in fan coil and horizontal main pipe, which are based on the research of exhaustion of condensate that occurs in the air conditioning system characterized by fresh air fan coil.

The results obtained are then compared with practical individual limits and the intervention level of the radiation protection system.

The effect of changes of intervention levels and meteorological conditions on the early emergency countermeasures is analysed for nuclear powerplant emergencies.

Extensive parameter studies have been performed with the program package COSYMA for probabilistic accident consequence assessments to quantify by means of PRA methods the relationship among area of relocation, intervention level of dose for relocation and source term of release.

In order to remove the trace-interval horizontal disturbance, on the basis of studying digital filtering this paper presents a kind of horizontal prediction filtration algorithm which combines the IIR filter and predictive algorithm.

The project of sewage main pipes in north bank of the Xiaoqing River is a subsidiary engineering of sewage collection system of Jinan City.

Through introduction of spiral inner winding pipe technology application in Yuya road sewage main pipe maintenance and reforming engineering of Sanya city,the technical principle and implementing process of spiral inner winding pipe technology were illustrated,many advantages of the technology were generalized at the same time,so as to further popularization and application.

Computational method of designing storm water pipes of unattached drainage areas;
