Furthermore, we discussed the chaotic quasi-attractors in a simplified model and found that this chaotic set is the end-results of the image set of the discontinuous border of the system function.

另外，我们讨论了一个简化模型中的混沌类吸引子，发现这个混沌集就是映象函数不连续边界映象集的归宿。

In a kind of quasi dissipative systems the disappearance of some elliptic periodic orbits and the elliptic islands around them via a collision with the discontinuous border of the system function can be observed.

在一种类耗散系统中观察到了椭圆周期轨道及其周围的椭圆岛与映象不连续边界碰撞而消失的现象。

We investigate and discuss the strong whispering gallery mode mode dependence on inner-most air-holes of Dodecagonal quasi-periodic photonic crystal D2 (formed by 7 missing air-holes) micro-cavity and its fabrication tolerance by randomly varying the lattice of two separate regions. Hence, we design and fabricate DQPC micro-cavity lasers sustaining WGM.

在本论文中，我们藉由随机调变两种不同区域的晶格排列位置，来观察十二对称准光子晶体中WGM模态对共振腔最内围空气孔洞的依赖度以及其对制程上的容忍度。

This thesis builds optimal model which takes the four-cylinder double-acting Stirling engine model as objective function and takes actual conditions as constraints, and use quasi-Newton method and penalty function method to slove this problem.

论文以建立的模型为目标函数、以具体实际情况为约束条件建立了发动机参数最优化模型，应用拟牛顿法和惩罚函数法实现了对最优化模型的求解。

There are some benefits to being a quasi free person such as Frederick Douglass.

也有一些好处，以作为一个准自由人，如冯检道格拉斯。

As to how to avoid weaknesses of these two operators, scholars have made unremitting efforts. One of the most famous is the French mathematician Sablonniere P, who introduced and studied a kind of new quasi-Bernstein interpolation operators in 1992. This kind of operators have given dual attention to the Lagrange operator and the Bernstein operator merit, and have avoided the twos deficiency.

对于这两种算子如何扬长避短，学者们做了不懈努力，其中最为著名的是法国数学家Sablonniere P，他于1992年引入并研究了一种新的拟Bernstein插值算子B上标(k 下标 n，，这是一类介于Lagrange算子与Bernstein算子之间的拟插值算子，这类算子兼顾了Lagrange算子与Bernstein算子的优点，克服了二者的不足。

Data of bubble- point vapor pressure and equilibrium temperature for 11 samples with different compositions originated from two kinds of hydrocarbon fuel s were measured by using an inclined ebulliometer with a pump- like stirrer on the basis of the principle of quasi- static method.

采用拟静态沸点计法测定两种碳氢燃料在11种不同配比下的泡点蒸气压和平衡温度，用Antoine方程关联了蒸气压与温度的关系，精度良好，同时计算了气化焓和气化熵。

This council was summoned by pope Julius II by the bull Sacrosanctae Romanae Ecclesiae, issued at Rome on 18 July 1511, after several schismatic cardinals, officially supported by Louis XII, king of France, had assembled a quasi-council at Pisa.
