试验单元 meaning in English

test units

On soluble block - transitive 2 - 56 , 7 , 1 designs
基因型同质试验单元较少的几种设计
The basic point of the two designs is to reduce the size of incomplete block , by using principle of confounding , to make fewer homogeneous experimental units fit to the size of incomplete block
这两种设计的基本特点是采用混杂的原理缩小不完全区组的大小，使较少的基因型同质试验单元可安排一个不完全区组所需的处理。
The confounding design and the balanced incomplete block design were introduced from the fundamentals of special design , which may be applied to the experiment with fewer homogeneous experimental units and more treatments
根据特种设计的基本原理，介绍了用混杂设计、平衡不完全区组设计以实施基因型同质试验单元较少而处理数较多的试验。
At first the design scheme of the test system of electro - hydraulic servo valve based on virtual instrument was proposed . according to this design scheme , the hydraulic test unit and measurement unit were developed
本文首先在介绍电液伺服阀特性和测试远离以及虚拟仪器技术的基础上，提出了基于虚拟仪器的电液伺服阀测试系统设计方案，以此方案研制了测试系统的液压试验单元和测控单元。
