base ratio meaning in English
碱基比例
Examples
- The base ratio of 1 : 1 for the bases adenine and thymine and the bases cytosine and guanine was the first clue to the specificity of base pairing in the nucleic acids
在核酸中的碱基配对高度专一性的原则决定了腺嘌呤与胸腺嘧啶，或鸟嘌呤与胞嘧啶之间的比值为1 ： 1 。 - In light of market risk , there are sensitivity measurement method and volatility measurement method as well as the concepts about risk measurement , such as variance , duration , 3 - coefficient , 5 - coefficient and value at risk . and in light of credit risk , there are accounting - based ratio measurement method and volatility - based measurement method , as well as the related concepts , such as credit rating , z - score , transition matrix , expected default frequency
其中，针对市场风险度量的方法包括灵敏度测量风险方法和波动性测量风险方法，与之相关的风险度量概念有方差、持续期、系数、类系数和在险价值；针对信用风险度量的方法包括基于财务比率的风险测量方法和基于波动性的风险测量方法，与之相关的风险度量概念有信用评级、 z分数、转换矩阵、违约频率。 - The elements of the reduced - jacobian matrix are functions of some parameters of the system . for example , effective short ratio , power base ratio , coupling impedance and load flow of the system . for single - infeed hvdc system with a parallel ac line , computer simulations using power system analysis software package ( psasp ) were performed
用一种简单的方法可以求得降阶雅可比矩阵，由于降阶雅可比矩阵的元素都是交直流混合系统中一些参数的代数函数，如有效短路比、功率基准比、连接阻抗和系统潮流等，因此，矩阵的特征值也与这些参数相关。
