(2)The transition period and the minimum output in Summer The limit of the transition period and the amount of oil in Summer is the same as expressed above, namely, crude oil heating temperature must not exceed 60℃, temperature of crude oil in the outlet pipe section can’t be less than 19℃ when it’s heated, without heating can’t be less than 23℃; Due to the limitations of the pipeline material, the maximum pressure of inner pipe’s crude oil can’t be more than 8Mpa during the transportation In accordance with the above-mentioned conditions, the minimum safe output of the transition period and every month in Summer from the Jibai’s first station to Baibao station on is calculated.
We can do computational analysis of various parameters, as well as a variety of needs, and quick calculation of all kinds of engineering conditions, as well as provide policy-makers with a better factual basis and calculated data, and reliable guarantee of the entire pipeline safe and stable production.

The key problem for the implementation of such a transmitter is the low efficiency of DRL at room temperature (RT).
This model does not agree with Kveder’s observation and one has to conclude that one of the key problems that remain open so far is how to find among the electrical levels detected with space charge region (SCR) spectroscopy technique those that are responsible for DRL.

The key to dryspinning CNT yarns is the availability of 'drawable' forests.
The term core-spun covers constructions in which the core comprises a significant proportion of the total material in the yarn.
Mechanical Properties: Of key interest is the effect of yarn twist on tensile strength and results for a range of twist angles as shown in Fig. 9. 0 200 400 600 800 1000 0 2 04 06 08 0 Twist Angle/degree Yarn Strength/MPa Data Hearle's Function Figure 9: The strength of dry-spun CNT yarns as a function of the twist angle.
