Based on the analysis to crankshaft-working system and turning/feed system for cold pilger mill and radio of two turning angles, the system is designed with computer.

本文通过对双回转送进二辊冷轧管机的曲轴机架与回转系统进行分析，以保证工作行程和轧件两次回转角分配比为设计前提，按照回转凸轮轮廓曲线的两过渡段的峰值加速度相等的设计准则，计算曲轴-机架与回转系统，实现了系统的最优化的设计。

A cathode ray tube (1) includes a tension mask (30) attached to a rectangular mask frame assembly (20) that has two long sides (22, 24) paralleling a central major axis thereof and two short sides (26, 28) paralleling a central minor axis thereof.

阴极射线管(1)包括附接到矩形的荫罩框架组件(20)上的张力荫罩(30)，所述框架组件具有平行于其中心主轴线的两个长侧边(22、24)和平行于其中心副轴线的两个短侧边(26、28)。

In this exper iment, we took the advantage of RNAi technique, microinjected tinman and wingless dsRNA into the early embryos in Drosophila respectively and got these two genes' RNAi phenotypes, which were very similar to that of their mutant, showing heart tube defects or no heart precursors formation.

实验运用RNAi技术，分别将tinman和wingless的dsRNA注入果蝇的早期胚胎，得到了这两个基因的dsRNA干扰表型，与两个基因的突变体表型非常相似，都表现为果蝇心脏前体细胞不能形成或心脏管缺失。

In addition this study suggested that the wheat variety 98-10-30 and Batis had the same resistance when no aphids fed on them. However, the variety 98-10-30 had better resistance for S. graminum, and the variety Batis had better resistance for S. avenae when they were fed by aphids. The variety Amigo had better resistance for S. graminum under all situations.

同时明确了3个品种对两种蚜虫的抗性状况，即在前期无蚜虫危害时，品种98-10-30和Batis对两种麦蚜的抗性相当；在前期有麦蚜危害时，品种98-10-30对麦二叉蚜的抗性较好，而品种Batis对麦长管蚜的抗性较好；品种Amigo无论在任何处理下均对麦二叉蚜的抗性较好。

Pollination biology on three mixed subpopulations with intermingled Pedicularis rhinanthoides and P. longiflora has been investigated in a three years project. Results show high flowering density can help to enhance pollination facilitation, and then increase reproductive output.

我们选取了两种局限分布在喜马拉雅地区的长管类马先蒿P.rhinanthoides和P.longiflora作了传粉生物学的详细研究，我们的目的在于阐述传粉昆虫在这两种植物生殖隔离中的作用。

In the experiment, two kinds of tubes with alternative diameters and material properties, and three kinds of flat-nosed cylindrical missiles with same length and various diameters are applied. Two classes including six operating modes are designed in the experiment.

在实验方面，本文采用了两种不同直径和材质的薄壁管试件以及三种长度相同，直径不同的平头弹体，设计了两大类六种工况下的实验。

Tuning nonlinearity is decreased by a factor of 2 and hence the variation of phase noise is significantly decreased compared with the VCO that uses a single pair of varactors.

在VCO的谐振腔中使用两对变容管，以牺牲适当的调节范围来换取调节线性度的提高，同时使VCO输出两个波段。

50KV. The larger tank capacitance allows the use of larger toroids on both coils on the twin system, and more than doubles individual spark energy, making the overall performance better and far more impressive.

较大的坦克电容允许就这两个系统的两个线圈使用较大的螺旋管，增加了一倍以上个人火花能量，使整体性能更好，更令人印象深刻。

The quasi steady state analytical method is used to calculate the temperature in the heat structure.

用集总参数法来计算热传导；在正常的工况下，用含两个传热区的两相对流传热模型，计算流体与管壁间的换热。

India - The Indus Valley civilization grows up along the banks of the Indus River in what is now Pakistan. The two most important sites uncovered so far by archeologists are Harappa and Mohenjo-Dara; both cities show considerable development including multi-level houses and city-wide plumbing.

印度——印度河流域文明沿着今天巴基斯坦境内的印度河岸而增长，两个至今仍未被考古学家掩盖的最重要地点是哈拉帕和摩诃杰—达拉，两个地方都展示出相当规模的发现，包括多级房间和全城铅管品制造。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
