Two technology including nitrocarburizing process and salt nitrocarburzing process haver been adopted. Several conclusions were obtained: firstly, nitrided layers consist of two layers including the outer white layer, mainly ε and γ′ with favorite errosion resistance, the inner dark layer consist of α-Fe.

再往里为扩散层，扩散层与原始组织无明显区别，是过饱和含氮的α-Fe固溶体，比原始组织更易受腐蚀；(2)试样经长时间氮碳共渗后，渗层最表面会出现疏松，这是因为Fe原子向外扩散，在ε相内造成Fe原子空位，空位向内扩散，并可能在晶界上或某些晶体缺陷处堆积，以致造成空洞。

However, the refraction of plane wave in reaction-diffusion system obeys Snell's law only for proper diffusion coefficients and system parameters.

在二维复金兹堡-朗道方程描述的反应扩散振荡系统中，就扩散对平面波折射率的影响进行了数值研究，从Snell定律出发导出了折射率的解析表达式，数值和理论结果表明：在纯扩散情况下，平面波的折射满足Snell折射定律，扩散只影响着平面波折射率的大小；在同时存在反应扩散情况下，只有在适当的扩散系数和系统参数下，平面波的折射才满足Snell折射定律。

Methods: Agar gel immunodiffusion test was conducted twice in agar gel plate with 0.1 mg/L bromophenol blue, first, agar gel immunodiffusion test was carried out with AFP-HSP70 cross-linking protein and AFP antibody, then the test was conducted again with the processed precipitation band and HSP70 antibody.

在含0.1 mg/L溴酚蓝的凝胶琼脂板上，进行2次琼脂免疫扩散实验，第1次是用AFP-HSP70交联蛋白和AFP抗体进行琼脂免疫扩散，把扩散后沉淀带处理后再次和HSP70抗体进行琼脂免疫扩散。

The results show that the main CO proliferation forms in coal bed are the Knudsen proliferation and the transition proliferation.

结果表明，CO在煤层中的扩散主要为Knudsen扩散及过渡型扩散方式，过渡孔的增加有利于其扩散，而微孔的增加则不利于其扩散。

The uniphase C with W/≤0.3 can be synthesized without being preheated. When W/ is higher than 0.3, the sample expansion increases with the increase of W content, the reaction between W and C is incomplete, the combustion products consist of W〓C, WC, TiC, C, and unreacted W. Preheating mixtures can accelerate the completion of the reaction among Ti, W, and C. The uniphase C with W/=0.4 can be synthesized by SHS at preheat temperature of 600℃. There are two kinds of powders with size of 2-4μm and size less than 1μm in the combustion products.

通过燃烧前沿激冷淬熄试验及产物形貌特征（燃烧块断面组织和产物多晶聚合体颗粒）分析，创新性地提出了两种体系的自蔓延高温反应机制。1熔化—溶解—析出机制：当燃烧温度较高时，燃烧前沿Ti粉熔化，W和C溶解于熔融Ti里，而后C从熔融里析出。2扩散—固溶机制：当燃烧温度不足以使燃烧前沿Ti粉熔化时，通过C的扩散先形成TiC层，其后C沿着热应力导致的TiC层裂纹继续扩散，与固态Ti核反应生成TiC；同时，C扩散至W颗粒，形成W〓C，而后通过C的继续扩散W〓C转变成WC；与此同时，WC固溶至TiC里，形成C固溶体。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

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.

也许他们将在壶穴里消失
