Random good picture Not show

(1) Chimney is more sensitive to vertical seism.

(2) Fourth, the load of seism is random.

(3) To meet the seism detections require of high accuracy, high resolving power, the measurement technique of Laser Doppler and detection technique of faint signal are further researched.

(4) It is valuable for anti - seism study based on the capability and safety evaluation.

(5) Studying on seism and geology and historical earthquake activity obtained some advancement in Anhui recent years.

(6) The time-history analysis subject to four Shanghai seism wave is done[Sentencedict.com], which reveals the seism response of the structure.

(7) The basins exploited by seism and drilling in the north part of Nanhai include Beibuwan, Yinggehai, Qiongdongnan and Zhujiangkou basins.

(8) Secondly, the transmission rules and characteristics of blasting seism wave are analyzed in the paper. The methods of analyzing and predicting blasting vibration are introduced in this paper too.

(9) This paper discusses the vibration velocity of blasting seism and the reaction chart of the blasting vibration, and offers some helpful suggestions about solving engineering blasting problems.

(10) Its response to seism has been analyzed by the response spectra method and the linear history method.

(11) Static analysis subject to wind and seism load is done and the behavior of frame-brace steel-concrete hybrid structure is investigated.

(12) So the crustal stability of NorthwestYunnan is determined dominatingly by the active fault and seism.

(13) The porosity and permeability of matrix, and the width, density and direction parameters of fractures were obtained by core analysis, well logging, seism and thin section observation methods.

(14) The vibration of each case from far vibration wave had a blurry border, presenting a likely continuous seism wave.

(15) In consideration of complex geologic characters and the contradictions existed in production of Huangjue Oilfield, an experimental study is conducted on interwell seism.

(16) Two familiar destroy formats, bending destroy and shearing destroy, appear to RC frame columns under seism action.

(17) A pressure predicting model is established by synthetically using the data of seism, well logging and well drilling in combination with statistical matching method and nonlinear inversion.

(18) Deconvolution is a method in common use in dealing with improvement of image resolution in ground seism.

(19) The acquisition system obtains the geological information through the geophone in seism prospecting.

(20) Middle column of large underground structures is the weak link in seism.

(21) The presented results may provide the theoretical fundamentals for the description of random excitations in predicating the dynamic responses of structures to explosion seism.
