Based on this, it analyzes effect to cannon mouth vibration caused by tube curve bringing bourdon domino effect. from deducing formula, it calculated connection of tube camber and cannon jump of angle, and discussed feasibility of carrying through shot modifying by tube camber
在此基礎上分析了身管彎曲引起的波爾登效應對火炮炮口振動的影響，並從炮身振動入手，通過公式推導，計算了身管彎曲度與火炮跳角之間的關系，從理論上探尋了根據身管彎曲度進行射擊修正的可行性。Non - metallic conduits and fittings for electrical installations - pliable corrugated, plain and reinforced conduits of self - extinguishing plastics material
電氣裝置用非金屬導管及接頭規范.自熄性塑料制普通和增強可彎波紋導管The temperature - dependent change in volume of an inert gas is transferred via a capillary line to a spiral bourdon spring, which by means of defined bending causes a pointer to be rotated
惰性氣體隨溫度變化而產生的體積變化通過一個毛細管傳導至一個螺旋波登彈簧，它的彎曲導致指針的轉動。This means that the dielectric property changes with height and allows a slight increase in the speed of a radio wave as we move upwards through the atmosphere. this in turn means that if a radio wave moves away from the earth at an angle less than 90 degrees, then the upper part of the wave travels faster than the lower part. therefore even under normal conditions this can in effect bend, or refract, the wave back down to earth
其中一種顯著的現象是：在一定的氣象條件下，在大氣邊界層尤其是在近地層中傳播的電磁波，受大氣折射的影響，其傳播軌跡彎向地面，當曲率超過地球表面曲率時，電磁波會部分地被陷獲在一定厚度的大氣薄層內，就好像電磁波在金屬波導管中傳播一樣，稱為大氣波導傳播，形成波導傳播的大氣薄層稱為大氣波導層。分享友人
