行推動脈沖 的英文怎麼說
中文拼音 [hángtuīdòngmàichōng]
行推動脈沖
英文
horizontal drive pulse-
For example, if there is a planet orbiting around the neutron star, it will wobble a little and the pulses will come a little early or late. we can then deduce the mass and the radius of the orbit of the planet from the arrival time of the pulses. this is how the first extrasolar planet is discovered
例如假若有一顆行星圍繞一顆中子星運行，它會令中子星出現搖動，引致脈沖的間隔變長或短，由此我們根據脈沖周期的變化，可推斷出行星的質量和軌道半徑，這亦是天文學家找出第一顆地外行星時所用的方法。The direct lateral force control is that more than one hundred small jet engines are installed around the missile before the barycenter. by firing up these engines produce impulse propelling force in order to adjust the position of the missile
姿控直接力控制方式是在導彈四周重心前徑向安裝的很多個小型噴流發動機，控制噴流發動機點火，產生脈沖推力，對導彈進行姿態調整。The phase matching and group velocity matching conditions of type - i and type - ii second harmonic generation ( shg ) are obtained according to the momentum and energy conservation laws. the group velocity delay of ultrashort pulse shg on clbo and the crystal length decided by the group velocity delay are analyzed and compared with bbo ' s
從動量守恆、能量守恆出發推導得出了超短脈沖倍頻的類、類相位匹配和群速匹配條件，對clbo晶體用於超短脈沖倍頻時的群速延遲以及由群速延遲決定的晶體長度進行了分析和數值模擬，並與bbo晶體進行了比較。The calculation formulas for velocity coefficients 2 and 5 for the throat and throat inlet section were deduced from the theoretical research on the velocity coefficients in time - averaged basic equations by use of the unsteady momentum equation and time - averaged value calculation method
摘要運用非恆定的動量方程和時均值計算方法，對脈沖液體射流泵時均值基本方程中的流速系數進行了理論研究，推導出了喉管和喉管進口段流速系數2和5的計算式。It preliminarily establishes a set of test theory and technical approach to wind tunnel test. specifically speaking, it includes following work : ( 1 ) theoretical analyses on key parameters of ao effect were made. from maxwell equation, the computation formula for focusing intensity of ordered disturbance and the computation formula for pulse peak intensity were derived
初步建立起了一套氣動光學風洞測試試驗的理論和技術，完成的主要研究工作有: （ 1 ）從理論上進行了氣動光學主要參數的分析，從麥克斯韋方程出發，推導了有序擾動的聚焦強度的計算公式及脈沖峰值強度計算公式。Experimental results confirmed this assumption : during the interstimulus interval ( isi ) ranged from 33 to 83 ms, with the isi luminance approximated to the mean luminance of the stimulus grating, a novel okn elicited by the intermittent display of stationary gratings was observed and recorded. it can be labeled as " intermittent - display - grating induced okn " ( idg - okn ). in the second part, considering that the biphasic visual impulse resp onse is the feature of the magnocellular ( m - cell ) pathway, and the m - type ganglion cells are damaged in the primary open - angle glaucoma ( poag ), we presumed that idg - okn of poag could differ strikingly from that of normal subjects
結果顯示，當間歇刺激間隔（ interstimulusinterval ， isi ）在33 83ms范圍內， isi期間亮度近似為刺激光柵平均亮度，我們觀察並記錄到這種新型的靜止光柵誘發的oknintermittent - display - gratinginducedokn （ idg - okn ） （ magnocellular ）路特性，而且原發性開角青光眼（ primaryopen - angleglaucoma ， poag ）是m型視網膜神經節細胞受損，因此我們推測，基於雙相視覺脈沖反應的idg - okn在poag病人與正常人比較中很可能出現顯著差2間歇刺激，對11隻poag眼和14隻正常眼進行對比眼動實驗。The influence of optical source chirp on femtosecond soliton interaction is studied numerically, and the unequal amplitude method can reduce the interaction. in addition high - order coupled equations governing the evolution of two orthogonal polarization components of the same wave are derived by using multi - dimension derivation expansion method of singular perturbation theory and the dispersion relation. furthermore, a class of optical solitary wave solutions, such as the bright - bright, dark - dark, bright - dark, and combined solitary waves are found under certain parametric conditions
數值研究了源啁啾飛秒孤子間相互作用，提出了抑制該作用的可能方案；用奇異攝動多重尺度導數展開法和色散關系推導了耦合高階非線性薛定諤方程（ chnlse ） ，並用行波變換法得到了一系列孤波解析解，分析了它們在光纖中傳輸的必要條件，也討論了它們的穩定性，為實現飛秒光脈沖在光纖中的無畸變傳輸作理論上的探索。分享友人
