例句与用法
1.
This is true as the brain and the fibrillating heart continue to consume atp and other energy sources 而脑和纤颤心脏继续消耗atp和其他能源，这是确定的。
2.
The expansion agents can only make up the shrinkage to some extent , and the compensation effects would be reduced when the retardener and fly - ash are used . the expansion agents are not panaceas to avoid the shrinkage cracking as expansion can also reduce the concrete soundness . under bad curing condition , the polypropylene fibrillated film fiber can improve concrete ' s anti - crarking property , while the nominal steels have very unobvious effects . to reduce the concrete shrinkage thus avoid the cracking , the former factors must all be taken into account in concrete proportion design to develop sound concrete 研究结果表明，水泥的品种和用量是影响混凝土收缩值的主要因素之一，当混凝土中水泥用量超过470kg / m ~ 3时，混凝土的收缩值超过400 10 ~ ( - 6 ) ，在约束状态下存在高开裂风险；采用细砂使混凝土单位用水量显著提高，收缩值也大幅增加；优质粉煤灰总体上能抑制混凝土的收缩，以超量方式掺入其抑制作用更加明显，但粉煤灰混凝土早期的粘聚性较差，应注意养护，以免失水产生龟裂；早强减水剂和缓凝减水剂都会使混凝土收缩值增加；膨胀剂只能补偿混凝土部分收缩，同时受缓凝剂和粉煤灰的抑制，而且膨胀使混凝土的体积安定性增加了不确定因素，膨胀剂不是解决混凝土收缩裂缝的良方。
