查询词典 secondary axis

In which whole length of the expanded equatorial line is assigned as horizontal-axis, and half of length of the expanded prime meridian is assigned as longitudinal-axis.

首先，我们提出了以中央经线和纬线的直接展开为基准的新的全球投影——纬平面投影，该投影以赤道线展开为横轴、以中央经线展开长度的一半为纵轴，纬线在纬平面上投影为一系列平行的直线段。

Because of the secular perturbation variations of the ascending node right ascension, the argument of perigee and the mean angle caused by the initial deviations of the semi-major axis, the inclination and the eccentricity are linear time-variant, then the active biases of the semi-major axis, the inclination and the eccentricity can realized the self-stabilization design of the elliptical orbit satellite constellation, and so the configuration stability will be improved.

通过初始偏差对椭圆轨道卫星的长期影响分析可知，轨道半长轴、倾角和偏心率的初始偏差对升交点赤经、近地点幅角和平近点角的长期摄动变化是线性的，因此通过主动偏置轨道半长轴、偏心率和倾角能够实现椭圆轨道星座构型的自稳定设计，从而提高其构型稳定性。

Central eclipse 中心食 A central solar eclipse occurs when the Moon's shadow axis touches Earth; a central lunar eclipse occurs when the Earth's shadow axis touches the Moon.

当月球的影轴於日食过程中经过地球时，该次日食便为中心食；月食方面，当地球的影轴於月食过程中经过月球时，该次的食就称为中心食。

Fixed axis wheel system can achieve a large transmission ratio, large-axis pitch, speed or change direction, it is widely used.

定轴轮系可以实现大的传动比、大的轴间距、变速或变向、故应用广泛。

By each gear wheel system is a fixed geometric axis is divided into a fixed axis and the epicyclic gear train, epicyclic gear train again planetary gear train and differential gear train.

按轮系中各齿轮的几何轴线是否固定分为定轴轮系和周转轮系，周转轮系又有行星轮系和差动轮系。

The destruction of the Axis forces in the Theatre was the focus of Allied operations. El Alamein was, in effect the closest the Axis came to achieving their goal.

但很可惜他的实力太有限而希特勒也不重视地中海战场，所以也就不可能获得任何重大的战果。1941年的北非战役可算是标准的拉锯战，但1942年却是具有决定性的一年。

Moreover, it is a secondary axis.

更重要的是，这是一个二级核心。

Step 1: Center the secondary mirror on the axis of the focuser drawtube.

把副镜中央置于调焦伸缩管的中轴。

Step 2: Here you adjust the tilt of the secondary mirror to aim the focuser 's axis at the center of the primary.

现在你已经调整了副镜的倾斜程度，把调焦座的中轴已经对准了主镜。

Nowadays, most of research are to build a transmutative Petri Nets through adding controlling place sets, controlling arc sets and controlling policy to the basic Petri Nets, while the Controlled Petri Nets could be used to argue many controlling theory problems conveniently and to induce many logically and physically supervisory and solve the Event Feedback Controlling Problems and State Feedback Controlling Problem in DEDS supervisory theory.

目前大多数的研究表现为在变形后的受控Petri网基础上，利用各种方法求得各种逻辑型、结构型控制器，解决DEDS监控理论中的事件反馈控制问题与状态反馈控制问题。
