1.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%,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%以上)等优点,适用于快速分析。收藏指正
2.for Z zeolites,the optimum mass fraction for doping of rare earth La was 10%,with enhanced initial activity and service life.
对于Z型分子筛,稀土元素La的最佳添加质量分数为10%,初活性和寿命都有较大提高。收藏指正
3.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％。收藏指正
4.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。收藏指正
5.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％的持续时间，是很重要的。收藏指正
6.The EGase activity was 807.5-fold as high as the initial enzyme activity using CMC as substrate and 14.4-fold using salicin as substrate.
以羧甲基纤维素和水杨苷为底物,测得纯化酶的活性分别是原酶液的807.5和14.4倍。收藏指正
7.The standard curves of inhibition ratios-methamidophos content were set up corresponding to different initial enzyme activity.
同时，针对不同的抑制前的初始酶活，绘制了相应的抑制率－甲胺磷含量的标准曲线。收藏指正
8.This essay puts emphasis on the research work in the Dai nationality sacrifial offerings using plants and worship, thus shows the kinds, contents , ways, meanings, initial mental activity and the related relations in using plants in Dai nationality sacrifial offerings.
本文通过对傣族民族（水傣）祭祀活动中对植物利用与崇拜的研究，揭示了傣民族祭祀活动利用植物的种类、内容、方式、附着意义、初始心态以及传承关系与方法，等等。收藏指正
9.Initial Study on Correlation of Se with Activity of Sulfate Factor of Serum from Kashin -Beck Disease Children
大骨节病区儿童血清硒与硫酸化因子活性关系的初步研究收藏指正
10.The effect of initial soybean oil concentration on lipase activity was investigated during the early phase of GA_(3)production by Gibberella fujikuroi 978.The result indicate that appropriate lipase activity could be induced and maintained by 1.0%(W/V) initial soybean oil,which would create an optimal condition to utilize added soybean oil efficiently in the fed-batch fermentation.
在藤仓赤霉菌(Gibberella fujikuroi)978菌株产赤霉素GA3的发酵前期,研究了发酵初始培养基中添加不同浓度豆油对发酵过程脂肪酶活性的影响,结果表明:添加1.0%(W/V)的豆油,在发酵48~60 h仍能对脂肪酶进行诱导,从而维持较高的脂肪酶活性,有利于菌体利用补加的豆油合成赤霉素GA3。收藏指正
