Linearization of Eq. (2) gives the relationship: (4) Where: the substrate removal rate (g.l−1.d−1); : the maximum utilization rate constant (g.l−1.d−1);: the saturation value constant (g.l−1.d−1); and is the sludge-bed volume of the EGSB reactor.
For low influent flow of 9L.h-1, 11L.h-1, the optimal was 4.0m.h-1 and 3.6m.h-1, and the corresponding topmost COD removal was 90% and 89%.
But with lower of 3.6m.h-1, 3.0m.h-1 and 3.1m.h-1, 2.8m.h-1, the COD removal only decreased to 89%, 86% and 88%, 85%, respectively.
At 26˚C, for 9L.h-1, 12 L.h-1, 15L.h-1, 24L.h-1 influent flow, the EGSB reactor could all have high COD removal efficiencies of 86.0%, 85.6%, 83.9%, 84.7%.

To complete drying, xerogel was placed at 250°C for 1 h.
The distinguishing characteristic peaks for cubic occur at 2θ = 30.2°, 35.2°, 50.3° and 60.02° for the (1 1 1), (2 0 0), (2 2 0) and (3 1 1) reflections [1, 3].

The getter alloys were prepared by arc melting in an arc melting furnace with a proportion of ingredients of n(Zr):n(Ti):n(Mn):n(Fe) = (1-x):x:1:1, (x=0.1, 0.2, 0.3, 0.4).
Therefore the elements ratio of n(Ti, Zr):n(Mn):(Fe)=1:1:1 tend to obtain the quaternary laves compound of high purity.

In such case Eq. 1 is rendered unusable in its original form, and thus needs to be adapted for cutting at changing speeds.
The cutting speed was 300 and 540 m/min, feed 0.11 mm/rev and the depth of cut 1 mm.
The error resulting from applying the approximate method at speed change of, for example, vc=100÷140 m/min stays below 1%.

In order to improve the efficiency of dephosphorization, the metallurgical workers around the hot metal and molten steel dephosphorization has carried on the dynamics, and also reached a consensus [1-3].
Theoretical basis and basic assumptions of the model According to the theory of ion,the response equation of rephosphoration can be represented as follows: （1） The application of the theory of double membrane[4], the mass transfer process of liquid steel to phosphorus are shown in fig 1 below.
