Figure 7. thrombus in a vein ( arrows ), identified by the absence of elastic fibers ( resorcin ? fuchsin elastic tissue stain, ? 125 ). in contrast, a nearby artery contains internal elastic fibers ( arrowhead )
圖7 .血管缺乏彈性纖維，證明為靜脈，並見靜脈血栓（箭頭） 。相反，附近的動脈存在彈性纖維。Iraqi insurgent leader claims group producing own rockets
伊拉克反叛領導稱已開始自行製造火箭彈Abstract : solid propellant rocket motors are preferred for most ballistic missiles because they need simple maintenance and can be launched quickly. but the conventional thrust termination devices limit the depletion of every stage ' s grain and increase some extra - weight. an improved method for designing a multi - stage solid rocket based depleted shutdown was provided. in order to solve the problem of lack of thrust termination devices, a device to adjust the burnout angle will match the final burnout velocity and satisfy the desired range. the method can also limit the detection from anti - ballistic missile system
文摘:由於維護簡單和發射快速，彈道導彈多用固體火箭發動機，但繁雜的推力終止裝置使各級裝藥不能耗盡並讓結構增重.提出了一種對基於耗盡關機多級固體火箭概念設計的改進方法，此方法滿足導彈系統主要的戰技要求.為解決無推力終止裝置的末速不準問題，可在末級發動機採用姿態調整裝置，對射角進行調整，配合末速以滿足射程要求.本方法還可抑制敵方反導探測The weapons are tow missile, two 7. 62mm or one 12. 7mm fn gun pod, one 70mm 7 rounds or 12 rounds pod
武器包括「陶」式反坦克導彈，裝兩挺7 . 62毫米或一挺12 . 7毫米機槍的fn武器吊艙和70毫米火箭的7管或12管發射巢。Collaborative optimization method is studied in depth, the causes leading to computational difficulty of this method are discussed by optimization theory and computation examples, and improve method which may solve this problem is presented. based on the comparison of several optimization methods and the characteristics of modern rocket - ramjet, step optimization pattern - a new integrated design mode is presented and is used to realize integrated design of rocket - ramjet. inner and outer fiowfield of a certain integral rocket - ramjet missile is simulated numerically using n - s equation
