某次测试成绩满分为150分,设n名学生的得分分别为a1,a2,⋯,an(ai∈N+,1⩽i⩽n),bk(1⩽k⩽150)为n名学生中得分至少为k分的人数.记M为n名学生的平均成绩.则( ). A. M=b1+b2+⋯+b150n B. M=b1+b2+⋯+b150150 C. M>b1+b2+⋯+b150n D. M...
An electronic device coupling apparatus is used to couple two electronic devices through a hinge. A first electronic device (221) is disposed within the main housing of a radiotelephone (101). The second electronic device (301) is disposed within a movable element (103) of the radiotelephone ...
Deformation mechanismEvolution of microstructureIncreasing testing temperature significantly decreases the tensile and fatigue strengths of the as-cast Mg-3.73Nd-0.56Zr alloy. The stress amplitude of the as-cast alloy tested at 150 掳C remains basically unchanged until fatigue failure. The deformation ...
Evaporation residue cross-sections have been measured for 19F+142,150Nd reactions in the energy range 15% below to 30% above the Coulomb barrier at the Inter-University Accelerator Centre, New Delhi, using the heavy ion reaction analyzer (HIRA). The measured fusion excitation functions were ...
The high phase-conjugate reflectivity of 150, by four-wave mixing in a diode-pumped Nd:YVO[sub 4], has been demonstrated. The phase-conjugate mirror was capable of correcting the phase aberration of a probe beam. The experimental diffraction efficiency of the transmission gratings was 60.Omatsu...
The sensitivity of the nuclear collectivity to the pairing strength in 150Nd has been investigated in a collective Hamiltonian based on the relativistic point-coupling energy functional with the delta-pairing force. With the increasing pairing strength, the potential energy curve becomes shallower and ...
We develop a compact high-frequency actively Q-switched Nd:YVO4/YVO4 Raman laser at 1525nm. The mode size stability and the mode overlapping are numerically analyzed to craft the resonator. Experimental results reveal that the compact cavity and the cavity dumping effect lead to the considerable ...
