scalar constant 中文意思是什麼
scalar constant
解釋
標量常數-
When the field is slowly - varying, the scalar field potential acts like a cosmological constant. in addition to the quintessence models, many other theories for dark energy have been proposed, including models based on super - symmetric gauge theories, super - gravity, small extra dimensions, large extra dimensions, quantum field theory effects in curved space - time. all these models are essentially based on the existence of a mass less scalar field acting at a cosmic scale
除了真空場模型外，科學家亦提出其他解釋黑暗能量的理論，這些模型建基於不同的物理理論或假設，例如超對稱規范理論超重力增加一些小或大的空間維數量子力學在彎曲時空的影響等等，這些理論模型，返本溯源，其實背後都假設存在著一個特性類似於宇宙常數的無質量純量場。 -
So it holds a ideal ability to anti - interference and has 2 scalar level resolution in location and measuring velocity than traditional radio induction technology. and the channel composed of the new radio induction system for communication is different from the parameter - constant channel and the traditional parameter - changing channel, its parameter is decided by the mutual induction between its antenna and induction - cable, by the location of its antenna, by the signal frequency passing through, its parameter has nothing to do with the time parameter. the channel composed of the new radio induction system is a new parameter - changing channel independently of time for communication
而且，由新型無線感應系統組成的通道既不是恆參通道，也不是一般目前所知的變參通道，其通道傳遞函數的幅值只與信號的頻率有關，與系統中天線和感應電纜之間的互感和天線的位置有關，而與時間無關，其通道傳遞函數的相位只與天線的位置有關，而與時間無關，由新型無線感應系統組成的通道是一種不隨時間變化的新型變參通道。 -
If a scalar field changes slowly, it resembles a constant, both in its fixed magnitude and in its lack of directionality ; relativity theory predicts it will produce a gravitational repulsion
如果純量場變化緩慢，它就會有固定的大小，而且沒有方向性，就像一個常數一樣；相對論預測，這種情況會產生重力排斥效應。 -
Complete space - like hypersurfaces with constant scalar curvature in lorentz spaces
空間中的具有常數量曲率的完備類空超曲面 -
This paper contains three chapters. we discuss the pinching problems on the length of the second fundamental form of compact space - like submanifolds mn with unit parallel mean curvature vector in the de sitter space spn + p. in particular, a sufficient condition for mn with constant scalar curvature to be totally umbilical is given
討論desitter空間s _ p ~ （ n + p ）中具有平行的單位平均曲率向量的緊致類空子流形m ~ n的第二基本形式長度拼擠問題，給出了具有常數量曲率的這種子流形是全臍球面的一個充分條件。 -
Theorem 1. 4 let m be a hypersurface with non - zero constant scalar curvature in rn + l spanning a sphere sn - 1 ( r ). if its gauss image lies in the semisphere, then m is a hypersphere cap
）為邊界的緊致常純量曲率（非零）超曲面，如果其高斯映照像落在一個以s ~ （ n - 1 ） （ r ）為邊界的半球面內，則m只有超球面蓋。 -
In chapter one, we investigate the influence of the boundary on the shape of the space - like hypersurface with constant mean curvature or constant scalar curvature in the lorentz - minkowski space ln + 1
第一章對于lorentz - minkowski空間中的常平均曲率或常純量曲率的類空超曲面，探討了邊界對超曲面形狀的影響。
