一组

Lead-in Ask students to look at our classroom and say what's in it.

俩人一组用上面问句做问答练习，检查几组。

We placed the lens holder, testing lens, and the assistant lens in the testing optical path. When the testing lens was mounted in the lens holder, we took five dynamic interferograms. After rotating the testing lens by 180 degrees along the edge of the testing lens, we took another set of interferograms. Then, we could evaluate the centering error of the testing optical element by analysing these two sets of interferograms.

在待测光程中加入透镜治具、待测透镜与辅助透镜，当待测透镜贴靠於透镜治具，此时撷取五张连续相移干涉图，之后由待测透镜配合透镜治具沿待测透镜外缘旋转180度，再撷取另一组干涉图形，最后由两组干涉图进行分析，以测量光学元件的偏心误差值。

Typically these methods find a set of basis images and represent faces as a linear combination of those images.

这些无监督统计方法找出一组人脸基图像，然后用这组基图像的线性组合来表示人脸图像。

Solving linear programming problems in a linear equation group inequalities or the condition of a linear function for the most value problem.

求解线性规划问题，即在一组线性不等式或等式组的约束条件下求某个线性函数的最值问题。

We use Aureate Group Mailer for this list type, and make a group for each list.

我们使用aureate组稍做这个名单类型，并提出一组为每册。

Then we apply it to a C-module V, where V is a n-dimensional vector space and the operator from C×V to V is defined by a linear transformation T of V, then we get a unique factorization of V and a right basis under which the transformation matrix of T is T's Jordan canonical form.

然后把它应用到一个具体的C-模V，其中V是n维线性空间，C×V到V的映射由V中的一个线性变换T定义，从而得到V的一个唯一分解，再结合线性代数有关知识给出V的一组基，T在这组基下的变换矩阵恰为T的Jordan标准形。

The larvae in the control group metamorphosed at day 20, and the metamorphosis rate increased gradually. The larvae in group 1 metamorphosed at day 30, but those in group 2 did not metamorphose throughout the experiment, which showed that the larvae did not have enough nutrition for metamorphosis.

对照组幼虫在第20天时开始变态，随后变态率逐渐升高，试验一组幼虫在第30天时开始变态，而试验二组幼虫在试验期间一直没有变态，表明该组幼虫的营养状况不足以支持其变态附着。

This design after determination frame layout, has carried on the level first the load generation of tabular value computation, extracts the wind load with the D value law the function, then uses the bending moment two methods of distribution to calculate the vertical load under the function structure endogenic force, and discovers most disadvantageous group of or a several group of endogenic force combination.

本设计在确定框架布局之后，先进行了层间荷载代表值的计算，用D值法求出风荷载的作用，接着用弯矩二次分配法计算出竖向荷载作用下的结构内力，并找出最不利的一组或几组内力组合。

Protein protein interactions play vital roles in numerous biological processes. These interactions often result in formation of insoluble and noncrystalline protein assemblies.

在这个研究中，杨俊和特拉华大学的同事Tatyana Polenova设计了一组新脉冲序列，他们用这组脉冲序列研究了用不同同位素标记的thioredoxin蛋白质组装体的分子内和分子间的界面。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
