用 c = 197MeV ·fm 就能恢复相关物理量的正确的 dim ension ( One can easily re2 cover the right dim ension of any physical quantities by making use of c = 197MeV ·fm ) . 这里 , dim ension 既 [1] 是量纲 ,也有数值的意思 ! 对于采用自然单位的做法 ,有人很不以为然 ,W esson 就...

When the interaction of the physical quantities and the unit prices of a given commodity is marked by regularities over time, whether in the recurrence of cyclical or seasonal patterns or in the persistence of secular relations, it is convenient to define the differential movement of quantity with...
However, if the system fails in the middle of loading the data, you need to restart the load, since you cannot use the redo log for recovery. If you are using Oracle Data Guard to protect your data with a logical or physical standby database, you may not want to disable redo logging...
The ScientificErrorAnalysis package provides representation and construction of numerical quantities that have a central value and associated uncertainty or error, which is some measure of the degree of precision to which the quantity’s value is known The ScientificErrorAnalysis package is introduced. ...
The maximum size of specimen that can be examined by SBF SEM is currently limited by the physical constraints of the ultramicrotome to around 800 μm2 (a limitation that may soon be overturned; Marx, 2013), but the total volume that can be examined covers a wide range from 1000 μm3 ...
We consider a common measurement paradigm, where an unknown subset of an affine space is measured by unknown continuous quasi-convex functions. Given the m
Both quantities change across dimensions and symmetry of the bounce, while only B(κˆd) further depends on the type of transition. This rewriting allows for an easier evaluation of the gravity decoupling limit κd → 0, which corresponds to κˆd → 0, and of gravitational corrections. ...
conceived to be a self-consistent sequence of steps leading to a desired result. The steps are those requiring physical manipulations of physical quantities. Usually, though not necessarily, these quantities take the form of electrical or magnetic signals capable of being stored, transferred, combined...
Heat energy storage systems described in this disclosure can be used for long-term storage of large amounts of thermal energy. In some cases, such systems receive electrical energy
