coagulation
Significado: The process by which a liquid, especially blood, changes to a semi-solid or solid state; the clotting or thickening of a substance.
Coagulation is most commonly encountered in medicine and biology, where it refers to the complex cascade of reactions that causes blood to clot and stop bleeding. The 'coagulation cascade' involves numerous clotting factors, and disorders of coagulation (such as haemophilia) are significant medical conditions. In water treatment, coagulation is a key step in purification, where chemicals are added to cause suspended particles to clump together for removal. In food science, coagulation occurs when proteins denature and solidify, as when egg whites set during cooking.
Ejemplos
- The haematologist ordered a full coagulation screen to investigate the patient's unexplained bruising and prolonged bleeding. 血液科医生要求进行全面的凝血功能筛查,以调查该患者不明原因的瘀伤和出血时间延长。El hematólogo solicitó un estudio de coagulación completo para investigar los hematomas inexplicables y la hemorragia prolongada del paciente.血液内科医は、原因不明のあざと出血の遷延を調査するため、凝固機能の包括的なスクリーニング検査を指示した。혈액내과 전문의는 원인 불명의 멍과 출혈 지속을 조사하기 위해 종합 응고 기능 검사를 지시했다.
- Aluminium sulphate is added during the coagulation stage of water treatment to bind fine particles into larger flocs. 在水处理的凝固阶段添加硫酸铝,以将细小颗粒凝聚成较大的絮状物。Se añade sulfato de aluminio durante la fase de coagulación del tratamiento del agua para aglutinar las partículas finas en flóculos más grandes.水処理の凝固段階で硫酸アルミニウムが添加され、微細な粒子をより大きなフロックに結合させる。수처리의 응고 단계에서 황산알루미늄이 첨가되어 미세 입자를 더 큰 응집체(플록)로 결합시킨다.
- Coagulation of the milk proteins is the first step in cheesemaking, typically achieved by adding rennet or an acid. 牛奶蛋白的凝固是制作奶酪的第一步,通常通过添加凝乳酶或酸来实现。La coagulación de las proteínas de la leche es el primer paso en la elaboración del queso, que se logra normalmente añadiendo cuajo o un ácido.乳タンパク質の凝固はチーズ製造の最初の工程であり、通常はレンネットまたは酸の添加によって行われる。유단백질의 응고는 치즈 제조의 첫 번째 공정이며, 통상 레닛이나 산을 첨가하여 이루어진다.
