In present paper, limiting range of explosive reaction for polybasic explosive mixed gasin coal gas and air have been carefully studied by a large number of experiments. The main factors which affects explosive range have been found out.
This paper uses S parameter to analyse the effect of external connective load on the measurement value of circulator isolation. The selection rule for external connective load at measuring different circulation state of the circulation isolation and the two limitation range values of isolation measurement error are also given.
2.there was significant effect on serum pH and carbon dioxide concentration (P<0.05) , the pH concentration was not exceed the limit range, but there was one group (303mmol/kg) which pH concentration were in the normal physiological range;
The utilization direction of coalbed methane and the existing technical difficulties are introduced,the influencing factors of explosion limit in transmission of coalbed methane are analyzed,and the measures for reducing the explosion limit range are put forward.
The results showed that the levels of salt concentration to the cell membrane of seedlings tolerated differently among cultivars (Daqingshan and Kentucky 0. 8 ~ 1 .2%; Jyusen, Fyliking and Park 1 .2~1. 6% );
This result indicates that polarity of solvents controls the relative content of saturated hydrocarbon and absolute concentration of biomarkers in coal extracts, but cannot change component and distribution pattern of biomarkers in coal extracts.
Symptomatic complications included fracture (7%), osseous deformity limiting range of motion (23%), vascular injury (7%), neurological compromise (10%), bursa formation (27%) and malignant transformation (27%).
In particular, the upper limiting range for effective detection (SNR>amp;gt;5) of small localized fires in dry- and clear-weather conditions is estimated at 7-15?km depending on operation mode, burning rate, and observation geometry.
The reduction state of photosystem II was higher by approximately 30% at each PFD beyond the light-limiting range in the blue-green algal partner compared with the green algal partner.
With phosphate and nitrate in the growth-limiting range, the growth of Microcystis was optimal at an N : P ratio of 100 : 1 (by weight) and declined at lower (nitrogen limitation) and higher (phosphorus limitation) ratios.
The study shows, however, that it is difficult to devise rigorous tests to distinguish between dispersal limitations and climate as factors limiting range limits in the past.
The authors attempt through the analysis of floral composition to demonstrate that the main forest vegetation in southern Yunnan is a part of tropical forest in Asia. However, the forest possesses obviously local characters because of the distribution have reached the limited range of the latitude and altitude.
A general fomura for calculating holographic digital data storage density is presented.It is demonstrated that by means of converging beam illumination, the digital data storage density pfthe holographic system goes beyond the theoretical limit derived by Y. Takeda, but it is still within the theoretical limi of storage density predicted by the properties of the optical system.
