二氧化碳

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.

中华超声影像学杂志/980401 摘要应用二氧化碳(CO2)肝动脉造影诊断 7 例门静脉癌栓，其造影增强声像图表现为：注射CO2微泡造影剂数秒钟后即可见癌栓光团弥漫性光点闪动，似白云翻滚或门脉实体回声内有数条和门静脉管径长轴平行的微气泡光带流动，停止注射后门静脉实体回声内仍有弥漫性非流动性增强光点，持续时间较长。

Carbon dioxide from SUVs is causing a steady upstick in the thermometer.

运动休旅车排放的二氧化碳正在让气温持续上升。

But the chances of Copenhagen delivering a deal that meets the goals for carbon dioxide emissions set by the United Nations Panel on Climate Change is vanishingly small.

但在哥本哈根缔结协议、达到联合国政府间气候变化小组制定的二氧化碳减排目标的可能性微乎其微。

Dr Weiss and his colleagues excel at the precise measurement of gases present in vanishingly small amounts—things measured in parts per trillion, rather than the parts per million used for carbon dioxide.

韦斯博士和他的同事在微量气体精确测量方面十分杰出。他们的测量单位是以亿万分之几计算而不是用于测量二氧化碳的百万分之几。

The carbon dioxide fire extinguishing system is able to put gas fire out after the gas supply source is cut, and it is also able to put out liquid fire, solid fire of fusible materials such as paraffin and asphalt, solid surface fire, deep-seated solid fire such as wincey, fabric, and paper, and electric fire, etc.

二氧化碳灭火系统可扑救灭火前可切断气源的气体火灾，液体火灾或石蜡、沥青等可熔化固体的火灾，固体表面火灾及棉毛、织物、纸张等固体深位火灾，电气火灾等。

The comparative research results showed that:(1)Thediurnal variation of the net photosynthetic rates in the aquatic leaves was a "double-peak", with an various "midday-decline", the time of the peak value appeared at about 10:00 A.M. and 13:00 P.M., while that in the xeric leaves was showed with invarious peak value and "midday-decline"; The diurnalvariation of transpiration ratesof both aquatic and xeric leaves appeared as a single-peak, the appearance time of peak value of the latter was earlier than the former and gradually decreased in the afternoon; The stomatal conductances appearance time of both of them were close to that of photosynthesisrate ,reached to the maximum in the morning and then gradually decreased: Diurnal variation of intercellular CO2 concentrationshows that: both aquatic and xeric leaves increased at first, and then exhibit a tendency of ascending within narrow range.(2) The net photosynthetic rates, photosyntheticallyactive radiation, stomatal conductances and transpiration ratesof both two kinds of leaves showed positive correlation, The correlation degree among them was prominent, there was significant negative correlation between The net photosynthetic rates and intercellular CO2 concentration.

研究结果表明：(1)水生叶片净光合速率的日变化曲线呈双峰型，出现明显的&午休&现象，峰值出现在10：00左右和13：00左右，但旱生叶片表现出的峰型和&午休&现象不明显；两种叶片的蒸腾速率日变化曲线表现为明显的单峰型，旱生叶峰值出现时间早于水生叶，中午过后逐渐下降；两种叶片气孔导度峰值出现时间和光合速率相近，均表现为上午升高至最高，随后逐渐下降的趋势；两种叶片胞间二氧化碳浓度日变化表现为：整体上先下降，然后有一上升趋势：(2)两种叶片的光合速率与光合有效辐射、气孔导度、蒸腾速率呈正相关，全部达到显著水平；光合速率与胞间CO2浓度显著负相关。

In fact, the cause of paradoxical gas embolism in this case was still unknown.

事实上，这个病例发生paradoxical二氧化碳栓塞的原因仍然是未知不明的。

We speculate rapid pneumoperitoneum introduction pushed CO2 into the abnormal vasculature, which communicates with systemic vascular system, causing a new pseudoaneurysm formation inside the tumor and gas embolism appearance.

我们臆测快速的二氧化碳充气制造气腹，可能将CO2 推入异常的肿瘤血管而产生pseudoaneurysm，而肿瘤的异常血管和身体的血液循环是相通的，可能产生气体栓塞。

Discolouration is due to an increase in the MAn monomer ratio of the increase, the product of an increase in the proportion of MAn, with the reaction of a polymer containing MAn more supercritical carbon dioxide from the medium of precipitation down in the cauldron at the end of a solid block.

变黄是由于增加单体配比中MAn含量的增多，产物中MAn的比例增加，随反应的进行含有MAn较多的聚合物从超临界二氧化碳介质中沉淀下来，在釜底形成块状固体。

Plunder melds and run with this jewel!

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
