一个定语从句的问题the rate of flow of visible radiation is called luminous flux,the symbol for which is the Greek letter Φ.可见光的流率叫做光通量,它的符号是希腊字母Φ.书上讲的是which指代的是前面的flux,因此
Like water moving through a hose, its flow will not be impeded unless the hose becomes blocked or kinked in some way. Symbol rate provides a useful way to estimate the fluctuating impedance for a particular line. The size of the bits has a rough approximation to the likelihood of bit ...
the electron will trace out a perfectly circulartrajectoryand will maintain that motion at a rate called thecyclotronfrequency, ωc, given bye/mB. The circle traced out by the electron has a radius equal tomv/eB. This circular motion is exploited in many electron devices for generating or ampl...
1.7 Interdomain Multicast Inspur INOS-CN provides several methods that allow multicast traffic to flow between PIM domains. 1.7.1 SSM The PIM software uses SSM to construct a shortest path tree from the designated router for the receiver to a known source IP address, which may be in another ...
Thus, the solution for the first element x1 of the column vector x = {xn} (n =1,2, …) is (299)x1 = −ζ1ξ1−ζ2ξ2−ζ3ξ3−ζ4ξ4−ζ5ξ5−…−ζn−1ξn−1−ζnξn. The solution (299) is the continued fraction of the order n. The system (...
Premises provided for symbolic rent of one euro per year. 以每年象征性一欧元租金提供的房舍。 UN-2 The euro was the most audacious of those symbols –a construct of dubious economic value, with well-documented fragilities. 而欧元是那些符号当中最为鲁莽贸然的一个——一个经济价值含糊不清...
Image as Phenomenologic Substrate THE flux of private mental events, part of our universal psychological experience, has intrigued and baffled philosophers, psychologists, and artists. It has become almost commonplace to observe that along with speech and thought goes a simultaneous flow of dreams—or...

A universally accepted mathematical model for viscous fluid flow is the famous Navier–Stokes equation, (10)ρ(Dv/Dt)=−∇ρ−∇×[μ∇×v]+∇[(2μ+λ)∇⋅v where μ, is the coefficient of viscosity,λ is the second coefficient of viscosity, and (11)Dv/Dt=(ρ(∂/∂...
The DC heat injection source is initially used for maintaining a temperature difference between the flow and reference sensors and the superimposed pulsed-heat injection source for maintaining this temperature difference constant with flow rate. It is shown that the flowmeter output frequency varies from...
