查询词典 substrate

The former consists of the spiculate FeAl3 phase which formed by the temperature deduction and the latter is composed of the lingulate FeAl3 and Fe2Al5 phases which embedded the substrate. Diffusion annealing as taken at 850℃, the structure changs apparently with increasing of the diffusion annealing time.

结果表明：浸镀层由表面富铝层及扩散层构成，富铝层包含降温形成的针状FeAl3相，扩散层由FeAl3、Fe2Al5相组成，形状如舌状指向基体。850℃扩散退火，随扩散时间的延长镀层组织结构明显变化。

The substrate specificity test showed that the lipolytic enzyme from strain DF-B6 was an esterase, and not a lipase.

底物特异性实验确定DF-B6菌株分泌的脂裂解酶为酯酶，而非脂肪酶。

The results showed that expression plasmid pET22b-lysB was constructed successfully. Highly purified recombination protein was obtained 33.2 mg from 1 L LB culture medium. A screening for His-LysB activity on esterase and lipase substrates confirmed the lipolytic activity. With p-nitrophenyl butyrate as substrate, the thermal stability of the enzyme was poor when the temperature was above 30oC. The enzyme exhibited higher stability at pH 5.0–9.5. The optimum temperature and pH for the lipolytic activity of His-LysB were 23oC and 7.5 respectively. Under the optimum conditions, the specific activity of His-LysB was 1.3 U/mg. Zn2+, Cu2+, Mg2+, Mn2+and phenylmethane sulfonyl fruoride severely inhibited the lipolytic activity of His-LysB.

结果表明：成功构建了pET22b-lysB表达载体，并从1 L的LB培养物中获得了33.2 mg高纯度重组蛋白；His-LysB具有分解脂肪的能力，属于脂肪酶；生物化学特性分析表明：丁酸对硝基苯为水解底物，His-Lys热稳定性不佳，30℃以下比较稳定，随着温度的升高，稳定性逐渐降低；该蛋白具有较高的pH值适应性，pH 5.0~9.5范围内稳定性较高；在23℃和pH 7.5时酶活力最高，其比酶活为1.3 U/mg；金属离子Zn2+、Cu2+、Mg2+、Mn2+和苯甲基磺酰氟抑制剂对酶活具有强烈的抑制作用。

A multi-layered mask includes a lithographically patterned photoresist and an un-patterned organic antireflective coating formed over a substrate layer to be etched.

多层掩模包括形成在待刻蚀的衬底层上平版印刷图形化的光致抗蚀剂和未图形化的有机抗反射涂层。

A preliminary study on substrate specificity of Lumbricus Bimastus nuclease.

双胸蚓组织核酸酶底物特异性的初步研究方法1。

Based on the sources, molecular weights, pI, characters of chromatography and electrophoresis, substrate specificities of these enzymes, it can be concluded that many kinds of nuclease-like enzymes have been found in the tissues of Lumbricus Bimastus.

根据这些酶的来源、分子量、等电点、层析和电泳等行为以及底物特异性等，初步证明，我们新近发现了双胸蚓组织中存在着多种核酸酶样酶。

A preliminary study on substrate specificity of Lumbricus Bimastus nuclease DNase E degradation studies showed that there were differences in degradation rate of the DNase E to different substrates.

双胸蚓组织核酸酶底物特异性的研究通过DNase E在最适反应条件下对几种不同底物降解速率的研究表明DNase E降解底物存在差异性。

A competitive inhibitor is usually structurally similar to the substrate, e.g. malonate is a competitive inhibitor of the enzyme succinate dehydrogenase.

与底物结构相似的物质能竞争性的与酶结合，从而使酶不能与底物结合而丧失其催化活性。

The results imply that the inhibition of NADPH is due to the earlier binding of NADPH to the enzyme which caused the arm to move from the condensation domain to the reduction domain so as to affect the binding of substrate malonyl CoA and inhibit the activity.

实验结果表明：NADPH对脂肪酸合成酶的抑制可能是由于NADPH在酶上过早的结合而使该酶的活臂向远离缩合中心的方向移动，从而影响了底物丙二酰辅酶A与酶的结合，造成酶活性的下降。

Masanobu Yamamoto, senior managing director at optical disc development division of Sony, said the firms were able to use paper in the new disc as the Blu-ray technology does not require laser light to travel through the substrate.

索尼光盘研发部门的高级常务董事Masanobu Yamamoto称，能够将纸作为新光盘的材料是因为，蓝光技术不要求激光穿透光盘片的基板。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.
