         The spherical and cylindrical dynamite sources as well as the concentrated force sources including weight drop,vibrator and shocking force are researched by using explosion mechanics and theoretical mechanics. The researches give source functions, relevant analytic and numerical results of the incident field in seismic diffraction tomography. By using elastoplastic theory,impulse theorem and Laplace transform,displacement Green's function is derived,and the convolution of Green's function with source functi...

            本大應(yīng)用爆炸力學(xué)和理論力學(xué)對(duì)爆炸震源（球狀和往狀）及集中力震源（落重、可控、敲擊）進(jìn)行了研究。給出了地震衍射CT中所涉及的震源函數(shù)形式和相應(yīng)的入射場(chǎng)解析解與數(shù)值結(jié)果，并采用彈塑性理論、沖量定理及Laplace變換導(dǎo)出了位移Green函數(shù)，進(jìn)而作褶積運(yùn)算，，最后得到位移入射場(chǎng)表達(dá)式及其圖表顯示。

         A retrospective investigation on technology and situation in the production of fireworks, the cause and hazard consequences of accidents in blossom firework enterprises was carried out. The risk factors and their origins, the potential effects on surrounding environments and residents, the manufacture processes producing special potential energy in these enterprises were summarized and assessed. In addition, the consequences of explosive fire accidents were assessed retrospectively by the principle of explo...

            通過(guò)對(duì)禮花行業(yè)生產(chǎn)工藝、生產(chǎn)狀況及生產(chǎn)過(guò)程中突發(fā)性事故發(fā)生的原因、危害后果的回顧性調(diào)查，總結(jié)出禮花行業(yè)這類含有特殊能量的生產(chǎn)企業(yè)在生產(chǎn)過(guò)程中危害因素種類、來(lái)源及其對(duì)周圍環(huán)境及居住區(qū)的潛在影響；同時(shí)應(yīng)用爆炸力學(xué)理論及對(duì)禮花廠火災(zāi)爆炸后果進(jìn)行了回顧性評(píng)價(jià)。應(yīng)用霍普金森標(biāo)尺化定律，對(duì)禮花廠突發(fā)性事故造成的危害后果進(jìn)行了定量評(píng)價(jià)，并提出禮花廠安全衛(wèi)生防護(hù)距離的標(biāo)準(zhǔn)。
