Jt91 - 200 artillety gyro altazimuth is a fix instument which can research the grid north automatically and determine grid north azimuth at any direction. it works by making use of the physical features of gyro and influences of earth rotation. the equipment of this instument will play a important role in topographic clement
Jt91 - 200型炮兵陀螺經緯儀是利用陀螺本身的物理特性和地球自轉的影響，實現自動尋找其北方向和測定任一方向線的真北方位角的定向儀器。該型炮兵陀螺經緯儀的裝備使用，對我軍炮兵測地分隊的測地保障發展將產生重大影響。 -
Abstract : it is observed that the sommerfeld ' s formula for a progressive spherical wave is not covariant with respectro the rotation of the coordinate system. it contains complex partial waves that are not physical. the standing wave representation of the same formula is shown to be covariant and physical. it is applied to solve the boundary value problem of fiber optics. the radiation modes as well as the guided normal modes are obtained in closed forms. the intensity distribution in various modes is obtained. it is remarked that the mode of critical refraction is missing
文摘:說明了球面行波的索末菲公式在坐標轉動下不協變.證明了球面波的駐波表示是協變的，因而是一個物理的關系式，故適用於圓柱坐標中各類波動方程的定解問題.作為一個例，應用於光纖光學，導出了受導簡正模和輻射模的表達式，以及各模式的強度分佈 -
The study has investigated and compared soil physical, chemical, biochemical properties of eight stands on paired sites in mountainous regions of northeastern china, trying to look for the mechanism of soil degradation and the change trend of soil properties in different age of plantations in relations to forest productivity. the eight stands are 4 first rotation of larix olgensis plantations with different age classes, the second rotation of larix olgensis young stand, pinus sylvestris var
本文通過固定和典型樣地，對東北山地不同生長發育階段落葉松人工林和二代落葉松幼齡林以及與二代落葉松幼齡林同一塊林地的樟子松幼齡林、天然次生林、落葉松水曲柳混交林等8個林型土壤質量進行了對比與分析，深入探討了落葉松人工林土壤質量降低的機理和不同發育階段土壤質量變化規律以及與森林生產力變化的關系，並提出了林地土壤質量調控措施。 -
Basic interoperability test is designed to check alarms on physical connections, the error rate of information delivery and the 2mbits cross - connect state when stm - 1 signals pass the transmission system. high - level interoperability test is to check the consistency of generated against readout overhead bytes, alarms and the performance monitoring as well as the synchronization, protection rotation, the interworking possibility of nm information and the o & m capability
基本互通能力測試包括：檢查物理連接是否告警，檢查信息傳送有無差錯，交換機stm - 1經過傳輸系統進行2mbits交叉連接的測試；高層次互通能力測試包括：開銷位元組產生和讀出的一致性，告警一致性，性能監視一致性，同步，保護倒換，網管信息互通的可能性及維護操作能力的測試等。 -
The interactions between atoms and molecules undertake a very important role in many physical processes and the investigation of rotation excitation cross sections of in the collisions of molecules with atons are an excellent method determining their interactions. many theoretical and experimental researcher have done a lot of reseach work hi this field and got plenty of theoretical and experimental data
原子分子碰撞過程中轉動激發截面的研究是確定原子與分子間相互作用勢的理想方法，許多理論和實驗工作者在這方面做了大量的工作，並取得了很多理論和實驗數據。 -
Secondly, the new physical intuition into reduced manipulability is given by means of decomposing reduced manipulability into arm length index and rotation angle index. the center index that expresses the positional relation between fault tolerant workspace and end - effector ' s motion is proposed
其次，通過將退化可操作度分解為臂長和轉角兩種指標，賦予退化可操作度新的物理解釋，進而提出反映容錯空間和末端軌跡相對位置的中心度指標。
