The positive parity collective states in the even-even 100Pd-116Pd isotopes are studied in the framework of the interacting boson model. A schematic Hamiltonian
The covariant phase technique is used to compute the constraint algebra of the four-dimensional space-times which are asymptotic to anti-de Sitter (AdS), such a
In this paper we have calculated the variations of the gap △’(0, d) and transition temperature Tc’ in small metallic grains as functions of grain size (or th
We study the synchronizing sensitive errors of chaotic systems for adding other signals to the synchronizing signal.Based on the model of the Henon map masking,
Neodymium doped phosphate glasses have been prepared by the semi-continuous melting technique. Their ab-sorption and emission spectra have been recorded at room
The interaction mean free path of He projectile fragments, produced by the collisions of 16O at 60 A GeV ina nuclear emulsion, has been investigated. In the pr
An equation describing the nonlinear pulse propagation in twin-core fibres with birefringence is derived. Particularly, the properties of the nonlinear coupling
小麦籽粒中的多酚氧化酶（PPO）和黄色素含量是影响面制品颜色性状的重要指标。多酚氧化酶是导致面制品在加工过程中发生酶促褐变的主要原因，而黄色素含量过高将导致面粉黄度增加，同时面粉的白度降低，二者都是导致面粉色泽性状不受中国消费者欢迎的主要原因。因此，通过遗传改良的途径培育出面粉白度高的小麦品种将成为当前品质育种工作的重点之一。研究表明，控制籽粒中PPO活性和决定面粉中黄色素含量的八氢番茄红素合成酶
We study the quantum dynamics of a single-Cooper-pair box biased by a classical voltage and also irradiated by asingle-mode quantized field. We demonstrate that
A magnetic duct is inserted between the cathodic arc plasma source and the chamber to eliminate the macroparticles. In this paper, the plasma output of the magn
