The carbon and nitrogen sources could satisfy the basic growth requirement of Geotrichum candidum link However, since its ability of utilizing starch and dextrin is not strong, the best pre-treatment of the waste water is sacchrification.

小麦淀粉废水的碳氮源能够满足白地霉生长的基本要求。但白地霉利用淀粉和糊精的能力并不强，因而最适的废水预处理方法是经过糖化。

Lathe Machining can realize automation or semiautomation with 2300mm of the maximum processing diameter. In addition, the processing range has been enlarged and processing precision has been upgraded for adding the heating-treatment shaft annealing furnace, carburizing furnace, handspike annealing line and quenching line with protected gas. Through technological reconstruction and equipment renewing, the grinding processing ability has been strengthened. As well, casting copper in cage workshop has realized melting by electric furnace.

车加工已实现自动化或半自动化，最大加工直径可达2300毫米，现已形成月产2000万元产值的能力，热处理在原有的基础上增加了井式退火炉，井式渗碳炉，推杆退火线和有保护气体的淬火线，磨加工经过技术改造和设备更新，使加工能力得到了增强，加工范围得到了扩大，加工精度得到了升级，保持架车间的铸铜实现了电炉化熔化，从而打破了保持架生产能力不足，依靠外协的局面。

The relative molar concentration ratios of c(superscript * subscript NO)/c(superscript * subscript NO2) changes as the temperature and pressure change. These results reveal that the two competitive reactions of C-NO2 homolysis (to form NO2) and isomerization may occur during the fast thermolysis of DNTF. NO formation from the cracking of furazan or furoxan rings may be limited by pressure.

结果表明，DNTF快速热裂解的主要产物CO、CO2、NO和NO2的相对摩尔浓度c与温度和压强有关，通过分析相对摩尔浓度比c(上标*下标 NO/c(上标*下标 NO2)随温度和压强的变化，揭示了DNTF中碳硝基C-NO2存在均裂生成NO2和异构化生成NO两条竞争分解的可能途径，同时压强可能抑制呋咱环和氧化呋咱环生成NO的可能性。

Various kinds of steel such as structure steel, tool steel, pipe line steel, reinforcing steel bar, common engineering steel and cast iron may be improved in their properties by vanadium nitrides and carbides.

已有的研究表明碳氮化钒添加于钢中能提高钢的耐磨性、耐腐性、韧性、强度、延展性和硬度以及抗热疲劳性等综合机械性能，并使钢具有良好的可焊接性能，而且它能起到消除夹杂物等作用，在高强度低合金钢中的应用效果更加明显。

A thin film of titanium carbide is obtained by vacuum evaporating oftitanium. With diffusion treatment, the existance of titanium carbide is identified by X-raydiffraction analysis. Quantatitive analysis is made by XPS to invetigate diffusion ofcarbon atom between diamond and titanium film.

用真空蒸镀法在金刚石表面镀覆Ti层，并经扩散处理使金刚石表面形成TiC膜，实现了金刚石表面的金属化。X射线衍射分析证实了TiC的存在，利用XPS定量分析验证了在金刚石表面碳原子与钛镀层之间的反应扩散模型。

Three different strains of Monascus sp including A13, As3.554 and As3.972 were used to investigate the effects of their culture conditions (initial moisture content of steamed rice, culture time, and addition level of glucose and sucrose used as rapidly-efficient carbon source) on the esterifying capacity of fatty acid ester (converted by ethanol and hexanoic acid).
