  rotation time
Thirty-eight patients with coronary artery disease diagnosed by conventional coronary angiography (CAG) underwent 16-slice CTCA (collimation: 16×0.75 mm; rotation time: 420 msec; kernel: 35f; effective current: 500 mAs; tube voltage: 120 kV).
      
Nevertheless, to date most of the studies concerning the atmospheric angular momentum functions and the Earth rotation time series have been devoted to their linear characterization and comparison, assuming their stochastic nature.
      
On the contrary, there are indications of a facilitation as: (1) the average rotation time per degree was shorter inflight than on the ground; (2) this difference seemed to be particularly marked for stimuli calling for roll axis rotations.
      
The observed distortion in the reconstructed images could be related to the ratio between the object activity variation and the camera rotation time.
      
Patients in group A (n = 274) underwent CT with 2-mm collimation and pitch of 2; those in group B (n = 86) underwent CT with 3-mm collimation and pitch 1.7; a 0.75-s rotation time was systematically used.

  rotational time
Images were acquired with a spiral-CT system Philips Tomoscan AVE1, using 250?mA, 120?kV, and 1-s rotational time.
      
The rotational time of a single transient can be calculated from the correlation function of the reduced linear dichroism signal which fluctuates over time as the molecule reorients in its surroundings.
      
Distributions of rotational time constants can be used to characterize the heterogeneity of molecular environments in the material.
      
Thus, the rotational time correlation function of the CH3 and CH2 groups contain a residuum term stemming from the slow motion within the same molecule.
      
The difference between the rotational time UT1 and atomic time scale AT was analysed in order to find the secular and periodic variations in the rotational velocity of the Earth.

Five factors have been detected affecting the results of EXT. When blood sample time is ≥240 sec, the differences in EXT were statistically significant (P<0. 050-0. 010). When the rotating time was 5 minutes, thrombus did not well formed. When the rotating time was raised to 10 minutes, poor thrombus formation was observed, the EXT was statistically different from that of a rotating time of 20 to 30 minutes (P<0. 050).

Five factors have been detected affecting the results of EXT. When blood sample time is ≥240 sec, the differences in EXT were statistically significant (P<0. 050-0. 010). When the rotating time was 5 minutes, thrombus did not well formed. When the rotating time was raised to 10 minutes, poor thrombus formation was observed, the EXT was statistically different from that of a rotating time of 20 to 30 minutes (P<0. 050). At a rotating speed of 3. 75 rpm, the thrombus was so poorly formed that EXT could not be performed. At the experimental temperatures of 25℃ and 43℃, EXT results were statistically different from those of 37℃'s. A statistically significant difference also existed when thrombotic lay up time exceeded 1 hour (P<0. 05-0. 005).
