An isometric immersed submanifold which receives the least possible amount of tension from the surrounding space at each point is called an ideal immersion.

當(dāng)一個浸入子流形在每一點處接受來自于外圍空間的最小張力時操碰免费视频在线观看，這種浸入稱為理想浸入。

Using the soliton theory we obtain a method to contract isometric immersions from indefinite space forms into indefinite space forms with the same index.

我們利用孤立子理論得到了構(gòu)造有相同指標(biāo)的不定度量空間型到不定度量空間型的等距浸入的方法黄片啪啪啪啊啊啊。

And we show that if such a immersion is also semi-parallel, it must be totally geodesic. Moreover the same results hold for semi-symmetric submanifolds in a nontrivial complex-space-form.

我們證明了如果它還是半平行的免费无码国产在线观看91，則它必是全測地浸入欧美黄色视频A一级黄色视频，而且這一結(jié)果對于復(fù)射影空間和復(fù)雙曲空間中的半對稱浸入也成立。

First, a large class of ideal Einstein and conformally flat immersions are proved to be totally geodesic, which generalizes a theorem of Dillen on the simplest ideal immersion.

首先證明了實空間形式中一大類理想的愛因斯坦和共形平坦浸入均為全測地浸入亚洲爽爽爽爽爽爽成年网站，所得結(jié)果大大推廣了Dillen等人關(guān)于歐氏空間中最簡單的理想浸入定理丝袜美腿视频无码二区30p。

Through survey carefully, we find that if depend on pouring velocity、structural shape of SEN entocoele日日狠狠久久影院、angle slope of outlet 18禁无码黄片、depth of infusion together to make the liquid steel in model revolution in an order flow then it can utilize this kind of energy completely.

In comparison with bugle shaped nozzle, bifurcated nozzle downward jet angle 45°, cow-nose nozzle and three-hole nozzle, in all, the last two are better than the former and bifurcated nozzle downward jet angle 45 is better than bugle shaped nozzle; Cow-nose nozzle is helpful for guaranteeing the product's quality, in order to protect jet flow from eroding the strand at narrow face, gain uniform temperature distribution at cross section and decrease heat flux, adding the block's width to 100 mm. Three-hole nozzle is advantageous to increase flux and casting speed, but should avoid weak shell thickness in the center broad. In the real production, setting the SEN's immersed depth or plugging the hole at the bottom can adjust the flow and temperature distribution in the mold.
