標量偶合
英文
scalar coupling-
Adopting the assummation that the quark interaction is the sum of the usual one - gluon direct exchange and the mixture of linear scalar and vector potentials, we structure the relativistic corrections of order v2 / c2to the cornell potential, including the annihilation potential for the quark and antiquark of the same favors which plays the same role with the one - gluon direct exchange at short distances. the effects of the relativistic corrections on the hyperfine splittings of quarkonium states are discussed, and a good fit to the available experimental data is obtained on heavy quarkonium mass spectra
采納庫侖勢源於單膠子直接交換,而線性禁閉源於標量和矢量的混合,同時考慮在短程區域與單膠子直接交換起同樣作用的同味正反夸克的湮滅,構造了靜態夸克-反夸克勢到v ~ 2 c ~ 2級次的完全相對論修正,並擬合計算了重介子偶素的能譜,討論了相對論修正對重介子偶素能級分裂的作用。4. the thrust measurement device was calibrated, and the accuracy was 2 % fs. at the same time the signal of thrust measurement was input to the computer. e - type chromel - constantan thermocouple was used to measure the temperature of mpt, and the accuracy was 5 % fs. the vacuum measurement was realized by using zdf - 5427m vacuometer, and the accuracy was 3 % fs
( 4 )對推力測量系統進行了標定並實現了計算機採集,推力測量系統最大相對誤差為2 fs ;溫度測量目前還只限於對mpt諧振腔壁溫的測量,使用e型鎳鉻?康銅熱電偶即可較容易實現,其測量精度為5 fs ;真空測量採用zdf - 5427m微機型復合真空計,其由熱偶計和熱陰極電離計復合而成,該真空計測量控制精度為3 fs 。For a x - directed line current with lengh much smaller than a wave length, the e - field pattern on coordinate planes in 3 - d space in the region from much smaller than line length to one or two wave length, the synthesized pattern by summation of the field of many line segments of hertz dipoles is independent of the number of segments, i. e. same field as a single hertz dipole
以水平面上三角形甚小於波長線電流為例,分割為若干小段之赫芝偶極所加總合成在三度空間任意座標平面上距離從甚大於線長到一兩個波長區域之電場場型與分割小段數量無關,即等同於一單一赫芝偶極之場型。2. dynamics analysis : by setting up jacon matrix differential coefficient sport is passed to descartes space. it makes terminal executing manipulator produce differential coefficient of acceleration and force in every different coordinates can be got. then the effective inertia, coincident inertia and gravity load of two manipulators are calculated by lagrange method. so generalized joint torque of each joint is got, and along with equivalent driving torque, actual driving torque of each joint can be worked out. 3
動力學分析:建立雅可比矩陣將關節空間的各關節的微分運動傳遞到笛卡爾空間,使末端執行器位姿產生微分運動,以用於求加速度及力在不同坐標系間的線性變換,再用拉格朗日法計算兩機械手的有效慣量、偶合慣量、重力載荷,從而計算得到各關節的廣義關節力矩,並與等效驅動力矩共同算得各關節的驅動力矩。With the modulus of elasticity as an index, the effects of glass fiber cloth, with the following conditions, were studied : various resin contents, addition of a silicone coupling agent, and resin spread at the interface between the veneer and the glass fiber cloth
以楊木膠合板模板的彈性模量為指標,分析玻璃纖維布浸膠量、偶聯劑用量、玻璃纖維布上下面單板塗膠量等的影響。Bridge, as a crucial conjunction and controlling place of road, is influenced complicatedly by many factors, for example, design normal, fixed number of year in use, material, environment, quality of maintainence, traffic, load and accident, etc. so, the construction of bridge will be changed and its capacity of bearing the weight will drop down gradually. in addition, bridge ' s erosion, aging, and damage, all these factors bring about hidden troubles for bridge ' s use
橋梁作為道路交通的關鍵結合部與控制部位,它受到設計標準、使用年限、工程材料、外部環境、養護質量、交通量、作用荷載、偶然事故等因素錯綜復雜的交互影響,必然會使橋梁結構內部產生變異性,導致承載力逐漸降低,再加上橋梁的腐蝕、老化、疲勞、破損,給橋梁的正常使用埋下了隱患。分享友人
