As the first attempt, this paper applies the laminar flamelet model to the typical diffusion combustion in diesel engines. A database of the laminar flamelet for a DI engine is built up in the phase space of the mixture fraction with the scalar dissipation rate as parameter.

以KIVA-3程序为基础，摒弃其原有的化学反应模型，模拟内燃机缸内多维湍流流场，并补充求解混合分数的时均值及其脉动均方值的湍流输运方程，得出各曲轴转角下混合分数的时均值及其脉动均方值的缸内空间分布。

Base on the turbulent shoot non-premixed combustion of methane/air, make a coordinate transform on flame for reactive scalar equation, build laminar flamelet model for two dimension steady state non-premixed turbulent reacting flows.

以甲烷／空气的湍流射流扩散燃烧为基础，对通用的反应标量方程在火焰面上进行坐标变换，建立二维稳态湍流扩散火焰的小火焰模型。

On the basis of the flow field, scalar transport equation was used to compute the gas residence time distribution.

在此基础上，采用标量输运方程研究了气体在旋风分离器内的停留时间分布规律。

Using scalar diffraction theory, Fresnel diffraction and the realization of Fraunhofer diffraction of light waves of wave-front propagation and the application of digital holography to help.

详细说明：采用标量衍射理论，实现菲涅尔衍射和夫琅禾费衍射，对光波的波前传播和数字全息的应用有帮助。

In chapter 4, sufficient conditions of at least one, two and multiple positive periodic solutions to a scalar functional differential equation with muti-finite delays are obtained by using a fixed point theorem introduced in [27] and [85] which is different from the one of a cone compression and expansion of norm type. It generalizes and improves some related results in the literature.

第四章利用文献[27]和[85]中所给出的不同于范数型锥压缩和拉伸的不动(来源：bc1cbcABC论文网www.abclunwen.com)点定理得到了具有有限时滞纯量泛函微分方程至少存在一个、两个和多个正周期解的充分条件，推广并改进了已有的相关结果。

Thus the new model can also be viewed as an interesting extension of TV functional from scalar space to vectorial space.

所以新模型也可以看成是TV泛函从一般的纯量值空间到向量值图像空间的有意义推广。

In noncommutative scalar field theories, the appearing of nonplanar diagrams is related to permutation symmetry of field functions in the interaction Lagrangian, while in NCQED we can not arbitrarily change the positions of field functions in the interaction Lagrangian because different positions of the field functions correspond to different representations of the gauge group.

这里需要特别指出的是NCQED的非平面图产生的原因与非对易标量场根本不同，非对易标量场非平面图的产生是和相互作用拉氏量密度中场函数间位置的置换对称性有关，而在NCQED中我们不能随便交换相互作用拉氏量密度中场函数的位置，因为场函数的不同位置对应着规范群的不同表示。

He then starts with a discussion of linear equations, matrices and Gaussian elimination, and proceeds to discuss vector spaces, linear maps, scalar products, determinants, and eigenvalues.

然后，他开始与线性方程组，矩阵和高斯消去的讨论，并着手讨论向量空间，线性映射，标产品，决定因素和特征。

理论分析和计算机仿真结果均证实了通用标量混沌信号同步系统及其控制器的有效性。

Both theory analysis and simulation results illustrate the validity of the general scalar chaotic signal synchronization system.

理论分析与计算机仿真结果均证实了控制方案的有效性。

I can not negligent, he should do what?

我不能不在意了，他要做什么呢？

It is very dangerous to swim in the river alone.

一个人到河里游泳是很危险的。
