The combustion events in the swirl chamber and the main chamber are processed differently. The combustion in the swirl chamber is broken into three phases: low temperature ignition, high temperature premixed combustion and flamelet diffusion combustion, while the combustion in the main chamber is only considered as flamelet diffusion combustion. The Shell ignition model, global Arrhenius equation and coherent flamelet model are used to describe low temperature ignition kinetics, high temperature premixed kinetics combustion and flamelet diffusion combustion respectively.

把涡流室式柴油机不同区域与不同时期的燃烧过程分开处理，将涡流室中的燃烧过程划分为三个性质不同但相互重叠的阶段：用Shell着火模型模拟的低温着火化学动力学反应阶段，用Arrhenius方程模拟的高温预混燃烧化学动力学反应阶段和用相关火焰微元模型模拟的扩散燃烧阶段，认为主燃烧室的燃烧只有相关火焰微元的扩散燃烧阶段。

Or for the health conscious, there are a lots of low-fat, flavorful products to grill – including soy burgers. Low-fat meats, like flank steak, are economical and marinated to tenderize (that's why it's cheaper – you can't just throw it on the grill like a high fat meat, to get a tender product).

低脂的肉制品，例如经济实惠的牛肋，通常是经过腌泡而变的很软（这也就是为什么它很便宜—你决不能像高脂肉类那样把它往烤架上一扔，这样烤出来的肉是不可能嫩的）。

Supporting type is suggested to be developed into 3-prop to improve adaptability besides 2-prop and 4-prop. The difference of caving difficulty degree of coal seam is the base of caving coal method at high, medium and low position. Caving with small step and open caving flashboard used widely not only cause serious mixture of coal and rock but also hinder the improvement of top coal recovery. So we suggest caving with large step or closing caving door. Four-bar-mechanism of hydraulic support restricts development of new style caving powered support. Stabilization framework of expansion link and all-shield caving tail beam at high, medium and low position are introduced here.

支架支护型式，除了两柱、四柱以外，建议开发三柱支架以改善适应性；煤层冒放性的差异，是高位、中位和低位放煤方法存在和使用的依据；目前广泛采用的小步距放煤和开放式放煤插板不仅造成严重混矸漏矸，也妨碍顶煤回收率的进一步提高，建议采用大步距放煤和可关闭放煤口；液压支架四连杆稳定机构，制约了新型放顶煤液压支架的开发，介绍了液压支架伸缩杆稳定机构及全掩护拖移高位、中位和低位放煤尾梁。

So the flip-flop output level changes from low to high voltage or high to low voltage on command.

因此触发器输出电平的变化，从低到高电压或前高后低电压对指挥。

早报讯昨（18）日，青城山—都江堰旅游景区内人声鼎沸，首个300余人的内蒙旅游专列团队游客到达了都江堰景区，这也是世界遗产地青城山—都江堰于9月29日重新开放以来，呼和浩特旅游迎来的首个旅游专列团队。

This so-called when necessary, there are two, first, the factory hard drive, hard drive works on a low-level format the hard disk; the other is when the hard drive certain types of Bad Track, the use of low-level format to achieve a certain degree of the role of mitigation, or shielding.

而这个所谓的必要时候有两种，一是硬盘出厂前，硬盘厂会对硬盘进行一次低级格式化；另一个是当硬盘出现某种类型的坏道时，使用低级格式化能起到一定的缓解或者屏蔽作用。

Excellent nurses have personality features such as high stability, high formidableness, high permanence, high self-discipline, and low anxiousness , low nervousness.

结果 ：优秀护士具有高稳定性、高恃强性、高有恒性、高自律性、低忧虑性、低紧张性等人格特征，以及良好的业务素质

De Kroz also has to execellent yellowing resistance, very good wetting and flow properties, low foaming, and is low in cost, making it an ideal choice for any formulator.

dekroz也execellent泛黄的阻力，很好润湿和流特性，低发泡并且成本低，使它成为一个理想的选择，任何formulator。

The main results are shown as follows:1.Screening freezing tolerant cultivars and lines of chrysanthemumTwenty seven lines of chrysanthemum grown outdoors were screened using \'injury rate\' and \'injury index\'.There were 7 cultivars and lines,which were relatively high tolerant to freezing treatment,i.e.,\'Jinbuhuan\',\'Xuetao\',\'Fuli\',\'Donglin 4\',\'Donglin 6\',\'Donglin 9\', and \'Donglin 13\'.There were 3 cultivars and lines,which were less tolerant,i.e.,\'Fenmeigui\', \'Donglin 1\',and \'Donglin 2\';The determination of electrolyte leakage,and contents of free proline,MDA,CAT,fructose,glucose and soluble sugars on 7 lines of chrysanthemums at different stages freezing showed that \'Xuetao\' and \'Donglin 4\' were more tolerant than others, and that especially \'Donglin 4\' was able to regulate its osmotic pathway to alleviate the \'injury degree\' caused by freezing conditions.2.Protein expression profile of chrysanthemum under low temperature stressTwo-dimensional liquid chromatography was applied to fractionate and analyze total protein taken from \'Donglin 4\' leaves grown at low temperature and at normal condition. Chromatography peaks of fraction were transformed to gel graph by ProteoVue software.

主要研究结果如下：1、露地菊抗冻品种和品系的筛选利用受伤率和伤害指数两项指标对27个露地菊品系进行耐低温筛选，筛选出'金不换\'、'雪涛\'、'富丽\'、'东林4号\'、'东林6号\'、'东林9号\'、'东林13号\'等7个耐低温品系，同时发现'粉玫瑰\'、'东林1号\'、'东林2号\'三个品系的耐低温能力最差；通过对不同自然低温处理时期，7个品系的电导率、丙二醛含量、脯氨酸含量、过氧化氢酶、果糖、葡萄糖和可溶性糖等指标的测定发现，'雪涛\'和'东林4号\'的耐低温能力要强于其它品系，尤其是'东林4号\'对低温的调节能力较强，在低温胁迫下，能够调节渗透途径减轻低温的伤害。2、低温胁迫下，露地菊蛋白质表达谱分析利用二维液相色谱技术，分离了'东林4号\'露地菊品系的低温处理和对照样品的总蛋白，通过ProteoVue软件分析发现：处理样品与对照相比共有蛋白差异点36个，其中显著增强表达的蛋白差异点有26个。
