The study on detonation front shape of a charge shot by High-speed photography Zhanlei Wang1, a, Yifan Li, Qun Mei, Huiping Wang 1Department of Engineering mechanics, Henan University of Science and Technology, Luoyang 471003, Henan, China awzldlut@sina.com Keywords: mechanics of explosion; detonation wave; high-speed photography Abstract: In order to obtain the detonation front shape and spreading process of detonation wave, Rotating mirror multi-streak technique was used to shoot the detonation process of charge initiated from three points by high-speed photography technique.
As a matter of fact, the detonation time of detonator, detonation intensity and nonuniformity of the explosive material would lead to the non- synchronous zero-time and the asymmetrical position of zero point.

Application of R/S rheometer in low temperature drilling fluid rheology determination Jiang Xiaoling a, Lei Zongming b ,Wei Kaic Chongqing University of Science & Technology , Chongqing 401331, China a cqustjiangxiaoling@126.com, bcqustlzm@163.com, ccqustwk@126.com Keywords: R/S Rheometer; Low temperature drilling fluid; Determination of rheological properties; Rheological parameters Abstract: With six-speed rotary viscometer measuring the rheology of drilling fluid at low temperature, during the high-speed process, the drilling fluid temperature is not constant at low temperature, which leads to the inaccuracy in rheological measurement.
R/S Rheometer The R/S rheometer is American Brookfield company produces concentric cylinder rheometer.The R/S rheometer test Newtonian viscosity, Also can measure the non Newtonian fluid viscosity function at a constant shear rate.At the same time, R/S rheometer can also be measured material rheological properties under different shear rate,The R/S rheometer using motor has high power precision,And the use of no gear and mechanical power sensing device optical decoder,accordingly, can be done without error control torque.The R/S rheometer can be stand-alone operation, can also be controlled by computer.The R/S rheometer can be used to measure the fluid shear thinning, thixotropy, the influence of the temperature.
