查询词典 temperature contrast

The crystallization temperature and pressure of clinopyroxene phenocrysts from the ankaramite and basalt were estimated on the basis of the clinopyroxene-melt equilibrium principle: 1345～1366℃ and 1.75～2.05Gpa for ankaramite, with average geothermal gradient of 20-24℃/km, suggesting anomalous heat or geothermal gradient in this region may be one of the key reasons to produce the porphyry copper deposits in the region. In contrast, those in the basalts fomed under a relatively low crystallization temperature (1129～1191℃), and the pressure (1.19～1.60Gpa) and depth (39～53km), suggesting that the basalt formed under a condition of lower temperature and pressure.

Reached slightly higher iodine delivery rates with a 300 mg l/ml iopromide solution than with 370 mgI/ml or iopamidol 370 mgl/ml.10The advantage of less concentrated (e.g. 300 mgl/ml) over more concentrated low osmolar contrast media in respect of injection and iodine delivery rates at room temperature and at 37°C was confirmed.11,12 In vivo, a slightly slower intravenous injection of concentrated contrast media may be compensated or even overcompensated because a higher concentration may be maintained after dilution by a given rate of blood flow.

到达递送以这 300 毫克 l│毫升 iopromide 解决评估的些微比较高的碘超过与 370 mgI│毫升或 iopamidol 370 mgl│毫升。10个比较不集中的（举例来说 300 mgl│毫升）结束更集中的低 osmolar 差别媒体的利益在注入和碘递送率方面在室温和 37 °C 被确认了。11，12在活泼地，一个集中差别媒体的些微比较慢静脉内注入可能被偿还或者平坦的 overcompensated 因为较高的集中可能在稀释之后被血流程的给定比率所维护。
