查询词典 variant

Twenty-four random primers were used to analyze the genomes of three descendant strains with steady hereditable variation produced form domesticated silkworm by artificial insemination with sperms of eri silkworm. The results show that in the RAPD patterns there are many amplified bands called" parental bands"which are similar to those of the female parent. At the same time, there appears varied amount of amplified bands called "variant bands" that are different from those of the female parent. The variant ...

采用24种随机引物，对以蓖麻蚕精子进行人工授精得到的家蚕后代中的3个稳定变异品系及其亲本的基因组进行了RAPD检测，结果显示，在变异品系的RAPD图谱中，不仅存在大量与母本相同的&亲本带&，同时还出现了不同数量与母本不同的&变异带&，包括&非亲本带&、&缺失带&及个别仅与父本相同的&目的带&，从分子水平上揭示了变异品系存在着明显的&偏母性&与&变异性&特点。

A it is predominantly derived from the initial variety or from a variety which itself was predominantly derived from the initial variety, while retaining the expression of essential characteristics that result from the genotype or combination of genotypes of the initial variety; an essentially derived variety may have been obtained by the selection of a natural or induced mutant or of a somaclonal variant, by the selection of a variant individual from plants of the initial variety, by backcrossing, by a transformation by genetic engineering, or by any other similar method

一个品种主要由原始品种演化而来，或主要由原始品种的实质性派生品种演化而来，同时保留了来自原始品种基因型或基因型组合的基本特征的表达；一个实质性派生品种可能通过选择自然变异或诱变或体细胞无性变异、原始品种植株的个体变异的选择、回交、基因工程的改造或任何其它类似方法而获得。

But in fact, the system of half-tracked air-cushion vehicle is over complicated. When the vehicle drives in an unknown soil, the parameters and structures of controlled member will change with load or disturbances. This system is nonlinear and time-variant, and it is very difficult to analyze its transfer function and state function quantitatively.

然而在实际工作中，由于本课题中的系统过于复杂，当行驶在未知土壤条件下时，被控对象往往随着载荷或干扰因素影响，其特性参数或结构发生改变，属于非线性和时变性的不确定系统，它的传递函数或状态方程难于用传统的定量分析方法加以实现。

The dynamic characteristics of the half-tracked air-cushion vehicle are different from other conventional vehicles. Its mechanical equation includes several parameters being related to propulsion system, air-cushion system and soil condition. This system is a higher order nonlinear time-variant system with a delay.

由于半履带式气垫车的力学特性不同于以往的常规车辆，其动力学模型包含与驱动系统、垫升系统、地面条件等有关的多个参数，属于大滞后的高阶非线性时变系统。

Now the variant of each gene is called an allele.
