Based on the prior art, the optical engine according to the invention has the improvements that, three optical axis steering components are respectively introduced into red, green and blue light illumination systems, and an optical axis lengthening structure is introduced into the green light illumination system, so that optical axes of the red, green and blue light illumination systems, each of which is from an LED resource to the optical axis steering component, are counterclockwise rotated for 90 degrees, parallel with each other, parallel with an optical axis of a projection lens, arranged in a same plane and positioned under the projection lens, luminous faces of three LED luminous chips of the red, green and blue light illumination systems are in a same plane, and the three LED luminous chips can be mounted on a same heat-radiating plate, therefore, the heat-radiating system has a simplified structure, and the optical engine has reduced size.

在背景技术所述的光学引擎的基础上作以下改进，在红、绿、蓝光照明系统中引入三个光轴转向器件和在绿光照明系统中引入光路加长结构，旨使：红、绿、蓝光照明系统各自的从LED光源至光轴转向器件部分的光轴朝逆时针方向转动90°、互相平行、与投影镜头的光轴平行、居同一平面和位于投影镜头的下方，红、绿、蓝光照明系统的三个LED发光芯片的发光面居同一平面，三个LED发光芯片可安装在同一块散热平板上，散热系统的结构简化，所述的光学引擎的尺寸减小。

But a camshaft driven directly by the crankshaft gear turns in the opposite direction.

Beside, he invents the world's first automatic astronomical apparatus _ a water-powered celestial globe and makes the seismographs for detecting directions of the earthquake and observing meteorological phenomena. According to legends, he also makes other instruments such as compass cart and mileage cart.

创造了世界上第一架自动的天文仪器——流水转动的浑天仪，创造了测定地震方向的地动仪和观测气象的候风仪，还制造了当时只有在传说中有过的指南车和记里鼓车等。

Circular disk was rotating about an axis tilted from the normal through the center.

圆盘绕一个通过中心与法线方向倾斜的轴转动。

If you see this lady turning in clockwise you are using your right brain.

如果你看见这个女生转动是顺时针方向，说明你使用了你的右脑。

F oliations forming subvertically against the porphyroblast margins have a wider r ange of orientations in the matrix because they can be rotated or destroyed by t he effects of reactivation of earlier formed foliations.

这种情况要求：后来的每一代褶皱都是由于渐进的、总体不均匀缩短作用造成的，这种情况表明：FIA保存着原始的运动方向，此方向未因以后的变形而转动。

If a car is skidding, first you have to turn the wheel in the same direction as the skid, and then you can establish and gain control.

这就像车打滑了，你首先得朝打滑的方向转动方向盘，然后再控制住车的方向。

Beaching out is one of the most common errors, and it must be watched carefully: the finger must be slightly raised, but it must stay on the same side where the arm is rotated until the arm begins its turn in the opposite direction and transmits its throw to the finger.

最常见的错误之一是手指伸出触及别的键，这必须要注意才行：手指必须是稍微举起，而且它必须与手臂转动的方向停留在一个侧面里，直到手臂开始转向相反的方向，并且将&投掷&传达到该手指上。

If you look away, she may switch from one direction to the other.

如果你把眼睛转看另一地点，再返回望看她，她也许转换从一个方向到另一方向转动。

Structure form adopts converse triangle beam double-hole connection welded by general electric trolley wall plate and steel plate, connection shaft, triangle beam bottom is connected with girder by nut and thrust bearing, triangle beam could rotate 360 degrees horizontally, thus realize whole set electric trolley horizontal rotation, largely reduce curve track curvature radius of electric hoist traveling mechanism.

结构形式采取通用电动小车墙板与一个钢板和连接轴组焊的倒三角形吊梁双孔连接，三角吊梁下面通过螺母及推力轴承与一个横梁连接，三角吊梁相对横梁可在水平方向做360度旋转，从而实现电动小车的整体水平方向转动，大大减小了电动葫芦运行机构弧形轨道曲率半径。
