temperature interval
1.temperature, ℃ interval, ℃ mm/sec1 28.86 ±0.08 ±0.192 24.17 ±0.12 ±0.203 17.79 ±0.26 ±0.22So it is advcntageous to use floats with lower flotation temperatures. With Aoat No.
2.It was found that strict control of sulfur content would reduce the breadth and temperature interval of solid-liquid diphase region and the segregation degree of alloy, as a result the corrosion resistance of alloy was improved obviously. A corrosion-resistant Hastelloy C-4 alloy with improved low segregation was developed.
3.Apatite Fission Track Analysis(AFTA) has been applied to the research ofthermal and tectonic history in petroliferous basin,as well as to direct oil-gas exploiting illrecent years. This technique depends on the observation that annealing of fission track inminerals, resembling the generation and maturation of hydrocarbons, is a function oftemperature and time,and that the temperature interval over which track anneals in apatiteis identical with that required for the maxium generation of liquid hydrocarbons.
5.Here we used reverse accumulated temperature methods to estimate postmortem interval and made accordant result with their true time.
6.It was found that as temperature inerease, the easy direction of magnetization changes gradually from [110] to [111] axis , in 153 K to 213 K temeprature interval,two easy directions of magnetization [110] and [111] coexist and do not change suddenly form [110] to [111] at one temperature.
7.In light of the geological characteristics of Qianmiqiao buried hill condensate reservoirs in Dagan, such as deep-seated reservoir, high bottomhole temperature, low reservoir pressure, greatly changeful petrophysical property and pore-cavity-fracture distribution, and long multi-payzone interval, etc.
8.The data about their inclusion thermometry and barometry indicate that the temperature and pressure during the formation of rocks and ore is 194—530℃ and 200—1900 bar,respectively. As it is proved that the petrogenesis and ore genesis were proceeded in the large interval of temperature and pressure,thus resulted in multistage nature of the metallogenesis corresponding to the incessant change of temperature and pressure.
9.The results show that well-bonding bimetal composite can be fabricated under followed processing parameters: pouring temperature of carbon steel at 1 520～1 530 ℃ and that of high chromium cast iron at 1 390～1 400 ℃; pouring interval between the two liquid metals in 150～180 s; mold rotating speed of carbon steel at 532～729 r/min and that of high chromium cast iron at 605～945 r/min.
10.Thus it may be inferred that the mud-sized crystalline dolostone in the Upper Eocene salt-bearing interval in the Qianjiang sag is peneprimary dolostone formed directly by chemical precipitation in a high-temperature,high-salinity,high Mg/Ca ratio and perennially meromictic salt lake.
