查询词典 CO2

Two kinds of oil were extracted from Styela clava and Ciona intestinalis Linnaeus by supercritical fluid CO2(SCF-CO2) and ethyl acetate. The results show that the two kinds of oil extracted from ascidian all contain high levels of plural unsaturated fatty acid, which are 89.84%(SCF-CO2) and 75.78% from Styela clava, 69.77%(SCF-CO2) and 61.11% from Ciona intestinalis Linnaeus respectively.

Solubility and stability of calcium arsenates under different CO2 pressures are studied based on the data of precipitation and solution experiments simulated by PHREEQC program. The result shows that calcium arsenates can dissolve incongruently by the effect of CO2 in high pH（pH〉8. 3）and make their solubility higher. The higher the CO2 pressure is, the lower the acidity of the incongruent dissolution is.

文章摘要：通过沉淀和溶解两方面的实验数据，应用PHREEQC程序模拟了砷酸钙在不同CO2分压条件下溶解度的变化情况，发现环境中的CO2可使砷酸钙盐在酸度较高（pH大于8.3）的条件下发生不一致溶解，使其溶解度升高；CO2分压越大，砷酸钙盐发生不一致溶解的酸度越低；CO2主要影响3：2和5：3的砷酸钙盐，而对4：2砷酸钙盐的影响较小。

Seven cases with portal vein tumor thrombus were diagnosed by CO2-hepatic arterio-sonography (CO2-HAS). Their ultrasonographic features of CO2-HAS were as follows: several seconds after the injection of CO2 microbubble contrast, bright cloudy flowing echoes or several flowing echo stripes along the long axis of portal vein were seen in tumor thrombus. During interrupted phase of CO2 contrast injection there were still scattered unflowing bright echoes in tumor thrombus.

The results showed that elevated CO2 increased the R/S ratio and the dry mass of both coarse and fine roots, indicating that the seedlings under elevated CO2 allocated more biomass to their belowground part. Compared with control, elevated CO2 increased the contents of reducing sugar, sucrose, and total soluble sugar in coarse roots significantly, but had less effect on those in fine roots. Elevated CO2 increased the contents of starch and total non-structural carbohydrate both in coarse roots and in fine roots. Under elevated CO2, the carbon content in coarse and fine roots had an unsignificant increasing trend, while the nitrogen content decreased significantly, which resulted in an increase of C/N ratio.

By research for deep faults and igneous rocks related to CO2 gas fields, the author considers that magma is the carrier for CO2 gas migration, while the development of igneous rocks is an important sign of the synchronous fault spatio-temporal activity. The 'migration' is one of the most important elements for mantle source CO2 gas accumulation, which means that there are deep faults connected to the mantle, directly or indirectly, and fault activity must be consistent with CO2 gas migration in space and time.
