心轴

Design of 10° FOV telecentric off-axis three-mirror anastigmatic telescope［J］.

李欢，向阳。 10°远心离轴三反消像散望远系统的光学设计［J］。

The zero-position is the position of the Z-axis, with which each measuring objective of the autocollimator

位是Z 轴的位置，通过它每一个测量物镜由自准直仪聚焦到各自自定心固定器的最高边缘上。

The axles run in two-row self aligning ball bearings on the gear side, and a standard sealed ball race on the other end in the sprung axle box, both 12mm bore.

两轴运行的排调心方对球轴承齿轮，和一个标准就在轴箱弹簧的另一端密封球的比赛，两个12毫米口径。

In this model, the small motion of the drum can be expressed by three translations of the centre of mass and three rotations about the inertial axes.

在这一模型中，筒体微振动的6个自由度以质心的3个移动和绕惯性轴的3个转动来表达；框架结构则按有限元法处理。

Core adjusting rolling bearing type 22300 has 2rows of symmetry rolling spherical and copper alloy suppting frame,there is no fixed circlip in inner circle,the roller is the longer type,it has the abillity to support more load,the circlip will lead while moving,it has the better performance of core adjusting,also it can compensate the tolerance of coaxiai degree.

调心滚子轴承22300CA型具有两列对称球面滚子和铜合金实体保持架，内圈无固定挡边，滚子加长，承载能力大，活动中挡圈由内圈引导，调心性能良好，能补尝同轴度误差。

By combination of balance equations of electron energy, current continuity equation and distribution function of electron energy, a model to simulate the coaxial RF discharge is set up.

结果表明：对于同轴环形波导，存在三种形式的低耦合损失谐振腔结构，即半共焦结构、半共心结构和平行平面腔结构。

Inflorescence rachis indumentum purple; leaf blade base shallowly cordate; epicalyx lobes ca.

花序轴毛被紫色；叶片基部浅心形；大约1/2的倍于花梗的副萼裂片。

Yuan Zhesheng's fiction often recounts family and father-son stories. His most celebrated feature is his speculation on time. Imaginative games in enclosed space also turn up frequently in his writings. Therefore, a research framework consists of time, space and human world is a criterion that delineates a fictionist's image of mind in three-dimensions.

袁哲生写得最多的是家庭、父子小说，最为文坛知悉的是时间的思索，最常出现的场景是闭锁空间的游戏想像，因此时间、空间、人间三向轴的研究架构，是为立体化小说家创作心象所设的凖的。

Gynoecium (2 or)3-5(-15)-carpellate, gynophore present or rarely absent; ovary superior, entire or deeply lobed, generally long styled; placentation basal, axile or parietal, rarely laminar; ovules 1 or 2 or numerous per locule; stigma entire or sometimes shortly divided at apex. Fruit fleshy or non-fleshy, generally a septicidal capsule, rarely a nut with accrescent sepals or a drupe, or separating into up to 15 blackish drupelets on a colored accrescent receptacle.

雌蕊群(2或者) 3-5 (-15)具心皮，雌蕊柄有或有时无；子房上位，全缘的或者深裂，通常有长花柱；胎座式为基底胎座，中轴胎座或者侧膜胎座，很少片状胎座；胚珠1或每子房室或许多的2；柱头全缘或者有时在先端短裂。

The simulation shows that the Corkscrew of beam centroid is a low frequency motion which overleaps the average eccentricity between centroid of beam and axis of accelerator and a dispersive effect.

计算结果显示，束心Corkscrew运动是叠加在束心平均偏轴上的一种横向运动，同时也是一种色散效应。

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。
