in situ reaction meaning in Chinese
地层内进行反应
Examples
- In situ reaction between oxide and al is a diffusing process of reaction atoms . in this process , an integrated reaction membrane is engendered in the interface of oxide and al firstly . then the synthesis reaction holds on through the reaction atoms " diffusion
氧化物与al的原位反应是一个反应原子的扩散过程，反应在氧化物与al的界面上进行并形成完整的反应膜，然后合成反应通过反应原子的双向扩散在界面上进行。 - So this research proposes a new idea to fabricate aluminum matrix composites by combining several oxides to react with al at the same time . this idea overcomes the shortages of cuo / al system and the other single oxide system . it extends in situ reaction system
因此，本研究采用多种氧化物cuo 、 tio _ 2 、 sio _ 2 、同时与al发生原位反应弥补了单质氧化物与al反应的不足，发挥了各自氧化物的优点，控制了剧烈的铝热反应，扩充了原位反应的热力学体系。 - It costs more than the traditional way and it is hard to control the process of the reaction . these disadvantages have led to some limitations of the composites " production and research . therefore , the developing orientation of in situ composites is to search the means of lowering the cost and controlli ng the process of in situ reaction
但外加法存在着诸如颗粒偏聚、润湿性差、界面强度结合低等缺点，而内生法由于增强颗粒是在基体内部原位反应生成，因此能克服外加法的缺点，但同时内生法所制备的金属基复合材料的成本太高、原位反应不易控制等缺点制约了复合材料的扩大应用，因此发展性能优异复合材料的出路在于寻找降低成本以及控制原位反应的措施。 - The experimental results show that in situ reaction between several oxides and al balances adiabatic temperature and controls the drastic reaction between cuo and al . at the same time , this kind of in situ reaction also accelerates the other replacement reactions and makes them react till to the end
实验结果表明采用多种氧化物原位反应法合理调配了不同反应的绝热温度，控制了cuo与al剧烈的铝热反应，同时促进了其它单质氧化物与al反应，使其能自我维持进行下去。 - But during the process of in situ reaction , in addition to the reinforced phase , composite will exit the other by - product ( such as fragility phase alsti and al4c3 ) , mean while , it is difficult to control the volume fraction of tic particles accurately , and lead to poor stability of material property
但是目前在原位反应时，除了所预计生成的增强体外，仍会生成其它副反应夹杂物(即脆性相al _ 3ti和al _ 4c _ 3的生成) ，同时对增强体tic颗粒的体积分数也难以精确控制，因而影响材料质量的稳定性。
