存在的性质

We discuss the model, presentsome properties of the model, and show the existence theorem of the solution.

分析了模型的基本性质，证明了解的存在性。

Then we prove the existence of positive solutions for difference equations by using fixed point theorem of cone expansion and compression.

另外，对非线性项具有混合单调性的情况，利用不动点指数性质及锥压缩与拉伸不动点定理等方法，得到了差分方程一个正解的存在性。

The linear growth condition is the most simple condition to ensure the existence of the global solutions.

一般而言，在缺少线性增长条件下，由局部Lipschitz条件仅能得出局部解的存在唯一性，而这就无法支撑任何涉及渐近性质的讨论。

It is the key question to lack the consideration for the nature and deep processes of Mesozoic lithospheric mantle.

这些问题的存在关键在于缺乏对中生代岩石圈地幔性质及其深部作用过程的了解。

In addition, the studies ofphotophysical and photochemical behavior of phenothiazines bymeans of laser flash photolysis were carried out.

此外，用激光闪光光解技术研究了吩噻嗪衍生物的光物理和光化学性质，并探讨了有三乙胺、四氰乙烯存在时对光解产物的影响。

The results show that the positive solutions are closely related to the spectral properties of certain differential operators of Schrodinger type.

结果表明，这些正解的存在性与一类Schrodinger型微分算子的谱性质密切相关。

What needs to be explored is not the validity of the secular trend, but the nature of the local influences working against it.

需要研究的并不是这种长期趋势是否真的存在，而是对这种趋势不利的区域性影响具有什么性质。

There is a huge seduction amongst teachers and healers of all kinds.

在所有性质的老师和治疗师中存在极大的诱惑。

Then we verify the topos property of RS and find thatRS has all topos properties except one, for it has no subobject classifier. There-fore RS is not a topos.

证明了I-粗集的范畴满足topos 的前四条性质，并证明了它不存在SC，从而证明了该范畴不是topos。

Through topological analysis, draw out the topological characteristic of near field in slot jet: the amount, connecting forms of critical point and primary bifurcation, it have the same topological characteristic with round jet in despite of they have a different flow forms.

我们发现虽然有限长窄缝射流与圆孔射流在流动情况上存在一定差异，但它们近区流场的拓扑性质却是一致的。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
