It was concluded that EBR increases the capacity of CO2 assimilation in the Calvin cycle, which was mainly attributed to an increase in the initial activity of Rubisco. 表明BRs对黄瓜的光合作用有直接刺激作用,而这种作用Rubisco初始活性的提高有关。
The sensor showed fast response (6s), excellent reproducibility (RSD=1.8%, n=10), selectivity and more measurement times (after 3000 times determinations, the enzyme activity was retained 85% of initial activity). 该传感器具有快速的响应(6s);良好的重现性(RSD=1.;8%25;n=10)、选择性、稳定性(传感器对葡萄糖溶液测定3000次后;酶能维持初始活性的85%25以上)等优点;适用于快速分析。
However, the MPH is reversibly inactivated by diethyl pyrocarbonate (DEPC) and the inactivation rate is 9.6 h~(-1). When adding neutralized hydroxylamine, the enzymatic activity of inactivated-MPH was restored to about 60% of initial activity. 然而二乙基焦磷酸酯对组氨酸侧链的化学修饰引起酶活性的大幅度的下降，其对酶活性的抑制率达到9.;6h~(-1)，当在酶的抑制体系中加了羟胺后，MPH的酶活力能够恢复到原来的60%25。
The inactivation rate depends directly on exposure temperature (37, 39), and it is important to investigate a method of protein stabilization and to estimate the shelf-life of the strip, i.e., the duration for maintaining 90% of the initial activity. 失活速度直接决定于暴露的温度，因而研究稳定蛋白的方法和测量免疫条的货架寿命，即保持最初活性90%25的持续时间，是很重要的。
The initiating activity and the affecting factors were investigated. The results show that the curing rate of the system of cycloaliphatic epoxide ERL-4221/[CpFeCp]BF_4 increases with the increase in the light intensity and the curing temperature. 通过考察[CpFeCp]BF4/环氧化合物光固化体系的固化活性及影响因素,发现其与脂环族环氧化合物ERL4221组成的光敏体系的光固化速度随着自然光照强度的增强和固化温度的提高,固化速度随之提高。
