APMP experimental results showed that properties of reed APMP such as brightness 57.8 %(ISO),breaking length 2.82 km and tear index(3.7 mN·m~2/g) can be obtained after two-stage alkaline peroxide pretreatment.
The industrial waste water containing nitrile was purified in the conditions of 7.5L nitrile containing waste water,gas flow 0.2m3/h,ozone 2.3g/h and static oxidation time 20min by two stage ozone/activated carbon catalytic oxidation.
The reaction kinetic study reveals that the reactions of NiCI_2 with N_2H_4 occurrs in two stages and the reaction orders with respect to Ni~(2+), N_2H_4 and Ni are found to be 1,0 and 1. The effects of the molar ratio N_2H_4/ Ni~(2+) on the reaction is also studied.
spring-corn adopts the cultivation techniques of plastic film covered at two stages,the agronomic measures for spring corn with yield more than 8250 kg/hm2 are 7920～8990 plant/hm2 in planting density,with the 288.6～352.4kg/hm2N fertilizer application and by the treatment of 304.6～498.0 mg/kg Eth at the 11～12 leaf age of the plants;
This paper mainly presents the test conditions of aspen CMP pulp bleached by H2O2. The result shows that a brightness of 79% can be achieved by pretreatment of 1% H2SO4 and two stages bleaching of 2%, 4%H2O2. The stability is excellent and yellowing is minimum.
For each test curve, the speeds of the two stage turbochargers were adjusted to the fixed data, and a compressor performance experiment was performed.
The system can get very high supercharging pressure when the speeds of the two stage turbochargers are rather low, which ensures the system's security and reliability.
Thermal analysis of the chloro complexes shows a three stage decomposition pattern for the Cu(II) complex and a two stage decomposition pattern for Fe(III) and Co(II) complexes to yield the respective metal oxides as the end product.
Based on the two stage magnetization process modeled by the authors, the size of the grain/lath and carbides in ferritic steels could be correlated with MBE parameters.
Turbo-pump with isolated two stage impellers for future rocket engine (Trial to drive impellers independently)
If reaction is carried out in following two stages, the result will be very good.
With increasing SVI, the average increasing rate of trans-membrane pressure increased, the stable filtration period was shortened, and the two stages (smooth stage and accelerating stage) of the trans-membrane pressure were more obvious.
Self-diagnosis is subdivided into two stages: determination of a reliably operative module for starting self-diagnosis and self-diagnosis of the state of other components of the system.
At the following two stages, the subsystems obtained from the primary subsystems by one-step right (downward) shift are checked in parallel as well.
The effect of six Siberian tree species on two stages of denitrification-N2O production and consumption-was studied.

A promising design of a КНК-type two-section gas-filled ionization chamber is described for the first time.
A 1.2-MeV Two-Section Continuous Wave Linear Electron Accelerator with 50-mA Average Beam Current
A 1.2-MeV compact two-section continuous wave linear electron accelerator with an average beam current of 50 mA and beam power of 60 kW is described.
A design of a two-section sampler is proposed; the sampler provides the rapid determination of deposition factors for heavy metals contained in aerosol particles deposited onto the end of a carbon electrode.
