Experimental investigation indicates that shock wave velocity and shock wave pressure of beginning which were produced with aluminize RHTL were smaller than that of insensitive RDX in steel plate, however, attenuating velocity of shock wave velocity and shock wave pressure which were produced under contact explosion with aluminize RHTL were quciker than that of insensitive RDX in steel plate, when steel- plate had been separately operated under contact explosion with insensitive RDX and aluminize RHTL, and shock wave press had changed suddenly in the interface between steel and aluminum, In the circumstances, the shock wave velocity had ascended suddenly and shock wave pressure had descended suddenly.

Compared with the initial value problems of scalar conservation laws with smooth flux function, the global weak entropy solutions for the initial-boundary value problems of scalar conservation laws with weak discontinuous flux function include the following new interaction types: a rarefaction wave collides with the boundary and is absorbed compltetely or partially by the boundary; a rarefaction wave collides with the boundary and the boundary will reflect a contact or non-contact shock wave; a contact or non-contact shock wave collides with the boundary and is absorbed by the boundary; a contact or non-contact shock wave collides with the boundary and a new non-contact shock will rebound from the boundary simultaneously or later.

The shock wave has made a nearly standard dodecahedron pattern on the surface of centre sphere. This pattern is the result of shock waves interaction from two adjacent detonating spots, and its position shows how the detonating of two adjacent spots acts, synchronized or not. The nice dodecahedron stroke patterns on the surface of recovered centre sphere indicate that this detonating method has good synchronization and spherical converging shock-wave.

Nonlinear flexural wave equation is solved by the Jacobi elliptic function expansion method. Two kinds of exact periodic solutions of the nonlinear equations are obtained, that is, the shock wave solution and the solitary wave solution. The necessary condition for existence of exact periodic solutions, shock solution and solitary solution is discussed, which is consistent with the qualitative analysis.

利用Jacobi橢圓函數展開法，對該非線性方程進行求解日韩妓女精品影院在线观看视频网站，得到了非線性波動方程的準確周期解及相對應的孤波解和沖擊波解欧美A一级黄色网站，討論了這些解存在的必要條件，這與定性分析的結果完全相同一级性爱视。

In the situation of shock wave, the interaction caused by the situation of one shock wave catching up with another is qualitatively analyzed with the result of the wave form: reflection rarefaction and incidence shock wave.

The calculated results indicate that a bifurcated A. wave can be formed when the shock passes through the flame, and pre-induced shock transmission in the flame leads to the formation of Mach stem, followed by spheral shock wave. The Rayleigh-Taylor and Kelvin-Helmholtz instabilities occurred in the flame induced by shock wave lead to the flame distortion and breakup.

objective to evaluate efficacy of extracorporeal shock wave lithotripsyfor treating ureteral stones in situ,investigate the cause of higher re-treatment rate.methods total of 687 patients with ureteral stone were received eswl between january 2000 and december 2004,included 455 male(66.2%) and 232 female(33.8%) patients,6 cases have bilateral ureteral calculi,12 cases have unilateral multiple calculi.hence,together 709 ureteral calculi were treated.patients upper ureteral calculi were treated in the supine position,for lower ureteral calculi patients were turned prone.to reduce eswl-induced renal trauma and pain,using lower energy source,adjusted power setting from 9.8 to 13.2kv,limited 1500 shock wavs per one session.no auxiliary procedure were used before eswl.the stone size was measured as the surface area of stone length by stone width on x-ray film.the interval between two treatment sessions was two weeks.results of 709 ureteral calculi,the overall stone free rate was 97.3%(690 calculi),re-treatment rate was 34.1%(292 calculi).according to the performed treatment sessions,one session 467 calculi,the mean stone size 37.27mm2,stone free rate 65.4%(464 calculi).two sessions 138 calculi,the mean stone size 62.48mm2,stone free rate 18.4%(131calculi).three sessions 52 calculi,the mean stone size 79.60mm2,stone free rate 7.1%(50calculi).four sessions 19 calculi,the mean stone size 101.63mm2,stone free rate 2.4%(17calculi).fivesessions 33 calculi,the mean stone size 119.33mm2,stone free rate 3.9%(28 calculi).overall 19 cases(2.7%)turned to other treatment modalities.of 335 upper ureteral calculi,303 achieved stone free (95.8%),re-treatment rate was 38.5%(129 calculi).of 374 lower ureteral calculi,369 achieved stone free(98.7%),re-treatment rate was 30.2%(113 calculi).the re-treatment rate of upper ureteral calculi was higher than lower ureteral calculi(p＜0.05,χ2=5.40).the difference of stone-free rate between upper and lower ureteral calculi was no significant(p＞0.05,χ2=0.15).conclusion eswl should be considered first line therapy for ureteral stone still.stone burden are the main variable of higher re-treatment rate,upper ureteral stone may moving with respiring during eswl.so efficinet shock wave was decreared,re-treatment rate become higher.
