Modification and synthesis of the cation antibacterial peptide CEMA

抗菌肽CEMA的改造与人工合成

The structure of metabolites in the urine from workers exposed to acrylonitrile was identified as CEMA by high performance liquid chromatography mass ( HPLC MS).

ACN现场工人的尿样经高效液相色谱质谱联机（HPLC MS）分离鉴定，确证尿中巯基尿酸结构为CEMA。正常人尿中未检出该化合物。

The international advanced design technology mainly includes the United States criterion Conveyor Equipment Manufacturers Association ( CEMA) and Germany DIN criterion. Technology differences are compared between ISO and CEMA.

国际上，大型带式输送机设计主要采用美国CEMA标准和德国DIN标准等。

Based on comparing the difference between ISO and CEMA standards, this paper introduces the way to analyze the design of large-scale belt conveyor by CEMA standard and offers the main design parameters and calculation method.

分析比较了ISO标准与CEMA标准的技术差异，并采用CEMA标准对某大型带式输送机进行了设计分析，给出了主要设计参数及计算方法。

The relationship among energy deposit, energy imparted and linear energy are compared. A comparison between cema and kerma, absorbed dose is made.

比较了沉积能、授予能和线能之间的关系，及比转换能与比释功能和吸收剂量间的关系。

In this paper, signal peptide was added before the N-terminus of CEMA with the intention to reduce its toxic to plant cells while maintaining the strong antibacterial activity.

本文通过在CEMA的N端添加信号肽，对其进行改造，以探索不降低抑菌作用的同时，降低其对植物细胞毒害作用的可能性。

It analyzes often-used design standards of belt conveyor and chooses CEMA standard as its basis.
