Choosing time delay as the control parameter, the stability of trivial equilibrium is discussed by analyzing distribution of the roots of the associated characteristic equation. It is found that Hopf bifurcation occurs from trivial equilibrium when the delay passes through critical values, then the critical values and their relations with system control parameters are obtained.

以时滞量为参数，通过分析对应线性系统特征方程的根的分布，讨论了平凡解的稳定性，得到了平凡解发生Hopf分岔而失稳的临界时滞量以及临界时滞量与系统控制参数的关系。

The Bayreuth performances also produced an invitation to appear at the Metropolitan where she made her debut as Sieglinde in Die Walküre.

由于拜罗伊特的超精彩演出，于是便产生制作了一份来自美国歌剧胜地大都会歌剧院邀请她登台献演的邀请函，在那儿她也是以瓦格纳超级四联歌剧《尼柏隆根的魔指环》之二《女武神》中的首要女主角"齐格琳德"作为其大都会首演的登台曲目。

Released in 1989, his second studio album entitled Une Présence was his more successful one and contains several hit singles, such as " Joue pas ", recorded as a duet with Joniece Jamison," Les Valses de Vienne "," Petit Frank " and "C'est toi qui m'as fait" which were all top two hits in France.

发布於1989年，他的第二张录音室专辑题为宇根的存在是他更成功的，包含几个单曲，如&茹埃双人舞&，记作二重奏与 Joniece 贾米森，&莱文贵宾圆舞曲&，&佩蒂特弗兰克&和& C'est 布袋葵 m'as 既成事实&的前两位都是在法国命中。

They began by preparing their own extracts from the rhizome, or root, of the plant, providing themselves with well-characterized materials to test and to compare with commercially available products.

他们开始撰写自己的摘录根茎或根的植物，提供自己的好教材的特点，以测试和比较，商用产品。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
