Dynamic derivatives of a 60° delta wing and F-18 aircraft model are calculated by this method, and then the effects of the amplitude,the frequency and the change of angle of attack on the dynamic derivatives are studied.

对60°三角翼和F-18飞机模型进行动导数仿真计算，研究了不同振幅、频率及迎角变化对动导数的影响。

Thus a filament yarn is characterized by its denier and the number of fibers in the yarn.

因此一个化纤长丝是以它的旦尼尔数和它纱线中的纤维数为特征的。

The experimental results show that this method is suitable to keep the spatial location undisturbed for the BCF, which has large denier and big monofilament numbers.

实验结果表明，对于纱线根数较多、旦数较大的BCF等纱线，该方法可保持纱线的纵向和横向的空间位置不改变，获得易于处理的原始数字图象。

In distribution of light in canopy sub-model, the concept of leaf-amount density function was introduced.

在冠层内光分布的子模型作者提出了叶数密度函数的概念，即单位体积的空间中叶数的多少。

Finally, discriminate analysis obtains that the degree of departmentalization has the obvious difference between the domestic and foreign retail properties.

最后利用鉴别分析得到国内外的商场在业种「部门化程度」上的确有明显的差异；国内的商场大多以单层面积较小、楼层数较高且以部门化的方式作为业种的配置型态；而国外的商场大多以单层面积较为广大、楼层数少且以非部门化的方式配置其业种。

Derivable mappings play an important role in the study of the structure of operator algebras.

引言导子是算子代数领域的一类重要映射，它对认识算子代数的结构有着重要的作用，如文献[2-3]。

In chapterⅡ, Firstly, we research the derivable mappings at unit and the anti-derivable mappings at zero point on Von Neumann algebra M.

证明了在单位可导和在单位反可导的范数连续的线性映射是M上的内导子，在零点反可导的范数连续的线性映射是M上的广义内导子。

At present, frequency-wavenumber domain expression has been derived by Lie algebra integral and exponential mapping, and we need to research the method of transform from wavenumber domain to space domain.

目前，通过李代数积分和指数映射的研究，已经导出频率波数域表达式，需要研究波数域到空间域变换的实现方式。

In order to study the stability of non-Newtonian fluid and its flow pattern discrimination method,the integral stability theory and local stability theory are applied to the concentric annulus flowing of plastic fluid and power-law fluid,then a relevant stability parameter expression of discriminating flow pattern is derived and set up in the paper.

针对非牛顿流体的稳定性问题及其流态判别的研究，将整体稳定性理论及局部稳定性理论应用于塑性流体和幂律流体在同心环空的流动中，建立和推导出相对应的判别流动状态的稳定性参数表达式。这些参数的临界值与牛顿液体流态准数雷诺数的临界值，同样具有与液体流变性无关的特点。

Three Texas drovers met on the highway and proceeded to dicker as follows: Says Hank to Jim:"I'll give you six pigs for a hoss; then you'll have twice as many critters in your drove as I will have in mine."

得克萨斯州的三个贩子在公路上碰头，打算进行下述的物物交换。汉克对吉姆说："我用6 头猪换你1 匹马，那么你的牲口数将是我所有牲口数的2 倍。"

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。
