投射

In Chapter 4, we define the induction of divisors and prove the existence of Galgebras of complete induction; through the analysis of Mackey formula, we give an equivalent characterization of the relationship between Green correspondence and free projectivity.

在第四章中，我们定义了除子的诱导，证明了完备诱导的G-代数的存在性；通过分析Mackey公式，给出了Green对应和自由投射关系的等价刻画。

Hockney surmises, however, that this convex mirror could be turned around and used as a concave projection mirror: If you were to reverse the silvering , and then turn it round, this would be all the optical equipment you would need for the meticulous and natural-looking detail in the picture.

但霍克尼的猜测是，把这个凸面镜前后反转过来，便能当成可投射的凹面镜来用：「如果你把银涂在凸面镜的反面，并将它反转过来，就变成能做出精细自然画面的道具了。

Then we introduce the concept of(n,0)-projective dimension for modules and rings.It measures how far away a finitely generated module is from being n-presented,and how far away a ring is from being Noetherian.

然后，我们介绍环与模的(n，0)-投射维数，它可以衡量一个有限生成模与n-表现模的差距，以及衡量一个环与Noether环的差距。

Portraits of the Crab Nebula captured in visible, infrared, and x-ray wavelengths are projected on screens in Monument Valley, Utah, in a long exposure beneath a star-filled sky.

以可见光、红外线和X射线波段拍摄的蟹状星云图像被投射在犹他州的纪念谷里的屏幕上，图片是在一片布满星星的天空下使用长时间暴光拍摄的。

It is the reflection of the people who created it.

它是一种创造了它的人的投射。

Note that in the image above, the dark outline and true CrossHatch shading have been omitted to clearly illustrate the Perspective Camera projection of the grid texture onto the surface.

注意：在图像上方，已经被忽略的黑色轮廓线和真正的交叉阴影着色，在透视摄像机里明显地表明格子纹理已经投射在表面上。

Once you do project, and face it, you will find it is only a hollow threat that will crumple into nothing.

一旦你进行投射，并面对它，你会发现这只是一个空洞的威胁，它会自行消失。

His cuirass of bronze did not protect him, and the spear stuck in his belly, so that he fell heavily to the ground.

伊多墨纽斯举起闪亮的枪矛，瞄准投射，击中健步杀来的俄斯鲁俄纽斯，青铜的胸甲抵挡不住，枪尖深扎在肚腹里。

Damnation is your judgment on yourself, and this you will project upon the world.

你判定自己是受天谴的，且将这观点投射到世界身上。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
