The effects of excess air coefficient and cylinder pressure on these spectra are also studied. The experimental resultS show that the three different combustion phases in a gasoline engine have different combustion characteristic spectra: a large number of atoms, molecules, ions and radicals which are in their excited states are existing during the ignition process, with the development of the combustion, the spectra intensities of CH, C2 radicals increase rapidly.

实验结果表明，汽油机三个不同的燃烧阶段具有不同的燃烧光谱特征：着火过程中，存在着大量的处于激发态的分子、原子、离子、自由基等活化中心的束缚态光谱，随着燃烧发展，CH、C2自由基的光谱强度明显加强；当减小过量空气系数时，光谱强度变弱并且着火延迟期增长；自由基特征光谱的光强变化曲线可以反映它们在燃烧过程中的浓度变化。

In common glass fiber reinforced polyolefine pipe, when the volume faraction is less than the critical value, the glass fiber can not act as reinforcement, on the contray, it would reduce the whole intensity of the compound material. However, when extruded in combined stress field, the extend intensity of the compound system increases when the volume fraction of glass fibers is less than the critical value. When the glass fiber volume fraction is higher than the critical value, the required glass fiber volume fraction of compound fibers extruded in the combined stress field is less than theory value.

一般玻璃纤维增强管材在常规挤出时当添加的玻璃纤维体积含量小于临界体积分数(当添加的玻纤的复合体系拉伸强度等于基体聚合物材料的拉伸强度时的玻纤体积分数)时，玻纤起不到增强的作用，反而会使复合材料的整体强度降低；但在复合应力场下挤出时，当添加的玻纤含量小于临界体积分数时，复合体系的拉伸强度不但没有降低反而升高了；当添加的玻纤含量大于临界体积分数时，复合体系要达到同样强度，经过复合应力场的玻纤增强管材需要的体积分数小于理论值。

You guys and gals are more than welcome to stick around here and debate whether or not Jason Kidd deserves the ranking he got until you turn blue in the face; I'm going to YouTube old Mavs highlights, and try to spot how many times Jason purposefully ignored Jimmy Jackson on the break while Toni Braxton sat courtside, suggestively crossing and uncrossing her legs.

大家不论男女都非常欢迎来讨论一下这个话题，就是直到你脸色开始变得忧郁之前，贾森-基德是否应该排在这个位置上；我会去 YouTube 网站上早一些早期的小牛队的片段，我是想告诉大家，在当年，当著名黑人女歌星 Toni Braxton 坐在场边看球时，不停地、有暗示性地交叉著她的双腿并暗送秋波时，基德曾经有多少次有目的地不理睬吉米-杰克逊。

After 10h ball milling, the alloy of carbonyl iron and carbonyl nickel began to form, and the sample kept its original bcc and fcc structure; after 100h ball milling, the sample became a solid solution with bcc structure; after 200h ball milling, the diffraction peak of Ni almost disappeared and the isotropic grains with D achieved, which was mainly attributed to the dislocations and disclinations of the nanocrystalline bcc FeNi suffering from severe plastic deformation by ball milling.

球磨10h时，羰基铁和羰基镍开始形成合金，但大部分Fe、Ni原子仍分别以bcc结构和fcc结构存在。球磨100h时，样品以bcc结构的FeNi合金为主，球磨200h后，样品中fcc结构Ni特征峰几乎消失，FeNi纳米晶达到最小粒径的平衡值，~8nm。高能球磨过程中，晶界区域的层错缺陷是合金化和纳米晶形成的重要因素。

For example, at the same content of nano-SiO〓, the average particle size of nano-SiO〓 treated with the silane coupling agent in ball mill was 97 nm, while the average particle size of nano-SiO〓 treated via ultrasonic dispersion reached 90nm.

在相同纳米SiO〓含量下，干法处理时，填料在基体中的平均粒径为97nm，一般湿法处理时，填料的分散粒径为90nm，硅烷偶联剂/分散剂复配处理所得填料在基体中分散效果最佳。

Evidence suggests that 1 under more stable stratification, the basic flow, if moving faster at low and high levels (particularly in the presence of jets there), allows a resulting meso-β unsteady wave to propagate eastward with respect to basic flow and even at greater velocity compared with it; 2 vertical windspeed shear of basic flow causes instabilities of the TWT perturbation; 3 considering the second derivative of basic-flow wind with respect to z (denoted by zz≠ 0 which is simply given as β* hereafter) the expression for the phase velocity of vortex Rossby wave is obtained, which is unidirectional in propagation with respect to basic flow; 4 VRoW has its physical origin from β*, i.e., from z-varying heterogeneities of y-direction averaged vorticity of the basic flow field; 5 VRoW phase velocity is associated with zonal wave number k, its energy is dispersive and the group velocity exists in the x direction; 6 when windspeed meets the condition of β*, TWT disturbance instability may be that of mixed VRoW and gravity wave; 7 if basic flow is subject to linear shear but does not meet the condition of β*, the TWT instability is that of inertia-gravity wave.

在大气层结比较稳定的情况下，如果基本气流在低层和高层较大(有可能存在低空急流和高空急流)，此时产生的β中尺度不稳定扰动相对于基流向东传播，甚至于快速向东传播。基本气流在垂直方向上的风速切变对于中尺度横波型的扰动起着不稳定的作用。如果考虑基流的二次切变，可以得到涡旋Rossby波的相速度表达式，涡旋Rossby波相对于基本气流是单向传播的。涡旋Rossby波产生的物理根源是基本流场的风速二次切变，亦即基本流场y方向的平均涡度在空间z方向上的不均匀所致。涡旋Rossby波的相速度与纬向波数也有关，它的能量是频散的，其在纬向x方向也存在群速度。在基本流场的风速存在二次切变时，横波型不稳定可能是混合的涡旋Rossby重力波的不稳定；而在基本流场的风速仅仅存在线性切变，不存在二次切变时，横波型扰动的不稳定则是重力惯性波的不稳定。

In chapter 5, we demonstrates for the first time that solvating the alkali metal ion in〓 by THF can change the electronic state of 〓 significantly.

在第五章，通过对〓(0＜x＜1)进行固体磁共振研究，我们首次揭示碱金属离子的溶剂化对于〓离子的电子态有显著影响(以间接方式，即通过影响〓之间的键合强度而起作用)：当〓离子与〓离子之间键合较弱时，〓离子处于〓电子基态；而当〓离子与〓离子之间键合较强时，〓离子则处于〓电子基态。

Furthermore, the structures of DNA molecules varying with concentration of new modification agent were studied, and it was found that when the new modification agent concentration was 1:1000, DNA molecules were successfully fixed and extended on the modified mica surface and well-distinguished DNA strands were imaged by AFM.

并进一步观察了不同DAPS浓度下DNA分子的吸附行为，发现当DAPS/甲醇体积比浓度为1：100时，DNA分子呈现出大而复杂的形态，发生了分子内和分子间的碱基相互配对；当体积比浓度为1：3000时，即没有分子内和分子间的碱基相互配对，也

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.
