The asymptoticbehavior of two ecological systems and the unconditionally stability and oscillations in kinds of 4-order delay difference equations are investigated by using analysis method, constructing Lyapunovfunctions, the logarithmic norm, charateristic roots theory and the bifurcation theory. Here, theasymptotic properity includes the uniform persistence, the global attractability of the solutions,the asymptotic stability of the positive solution local or global and the oscillations of solutions.

The works in the project just done can be summarized as five respects.(1) A device was designed to fabricate the asymmetrical resonant cavities by a pendant drop. A series ARCs with variable parameters provides a valuable experimental method for investigating the characteristics of ARCs.(2) The relationship between the number of active modes and the shape parameters in an ARC was investigated. The experimental lasing threshold was compared with theoretical result, the good agreement between two shown that it was the decrease of the number of active modes in an ARC that decreased lasing threshold.(3) Dye lasing gain was used to enhance the signals of stimulated Raman scattering of the weak gain Raman modes in a circular cavity made by a pendant drop, the instantaneous SRS spectra of weak gain Raman modes in ethanol was obtained by this new method.(4) The SRS signals of minority compound in a binary chemical complex was obtained by using dye lasing gain method. The detection concentration of minority compound was reduced to an order compared with normal SRS method.(5) A cylindrical circular cavity was formed by a liquid jet, which was used to reduce the pump intensity required for laser induced plasma spectroscopy. The limit of detection of trace element in aqueous sample was greatly decreased by this new method.
我们设计并成功制作了使悬垂液滴连续变形的装置,用此装置可以方便地改变非圆对称谐振腔的几何参数,为ARCs的研究提供了一种有效的实验方法;研究了ARCs中活性模式数和变形参数间的变化规律,激光阈值的数值计算结果和激光辐射的实验结果作了比较,二者吻合的曲线说明ARCs中活性模式数量的减少是受激辐射放大阈值降低的原因;在由单元化合物构成的微型圆对称谐振腔中,首次尝试用"激光增益"增强弱增益拉曼模式的受激拉曼散射信号,获得了乙醇分子中弱增益拉曼模式的瞬态SRS光谱;在由二元混合物构成的微型圆对称谐振腔中,用染料的激光增益增强了少量化合物的SRS信号,把少量化合物的SRS信号探测浓度降低了近一个数量级,在SRS应用于瞬态过程的组份分析方面做了卓有成效的探索;用石英毛细管形成的稳定液拄构成拄形谐振腔,降低了激光诱导等离子体光谱需要的激励能量,有效地降低了水相样品的痕量元素分析极限,为LIPS应用于微量元素的化学分析开拓了一条新的技术路线。

The speed of a computer is affected by the number of bits it can process at once. For example, a 32- bit computer can perform arithmetic and manipulations on 32-bit numbers, whereas a 16-bit computer must break large numbers into 16-bit quantities, making it slower.
电脑的运算速度会受到它一次可以处理位元多寡的影响,例如32 位元电脑一次可以进行32 位元的运算,而16 位元的电脑因为每次只能进行16 位元的运算,所以它必须将比较大的数打散成16 位元的量,所以这样会造成速度变慢。
