Instances where carbon dioxide usage is extremely low, heat leak into the tank is sufficient to maintain the contents above 245 psig and a pressure buildup coil is not needed.

psig。在二氧化碳用量极低的隔热场合，泄漏进容器的热量足以使内容物的压力维持在245 psig以上，因此不需要压力积累蛇管。

In isolated instances where carbon dioxide usage is extremely low, heat leak into the tank is sufficient to maintain the contents above 245 psig and a pressure buildup coil is not needed.

在二氧化碳用量极低的隔热场合，泄漏进容器的热量足以使内容物的压力维持在245psig以上，因此不需要压力积累蛇管。

In the first test, the water had more than six times the usual amount of carbon dioxide, and the little fish grew otoliths 15% to 17% larger than normal.

Different from many other researches the Henkel-Esterification process was studied here which starts from 1,8-naphthalenedicarboanhydride. In the Henkel reaction of 1,8-naphthalenedicarboanhydride to 2,6-naphthalenedicarboxylic acid (abbreviated as 2,6-NDA) non-cadmium catalytic system was used. In atmosphere of carbon dioxide 1,8-naphthalenedicarboanhydride can be effectively converted to 2,6-NDA in the temperature range of 300~340℃ with zinc carbonate as catalyst and the yield of 2,6-NDA can reach more over 62%.

和国内外绝大多数研究不同的是，论文结合公司自身的原料资源优势和长远规划，提出了从工业苊深加工产品—1，8-萘二甲酸酐出发，经过非镉系催化剂催化转位，然后再进行非酸催化酯化合成2，6-萘二甲酸二甲酯的工艺路线，并对工艺过程中涉及的成盐过程、催化转位反应、酯化反应等进行工艺参数的重点考察，对合成产物进行分析确证。

The extracting study on pumpkin seed oil was carried with the supercritical fluid carbon dioxide extraction technique.

应用超临界CO2 萃取技术，研究了南瓜子油的提取工艺，着重探讨了原料预处理、萃取压力、温度、萃取时间、CO2 流量对油脂萃取率的影响，优化了工艺条件：压力 3 0MPa ，温度 45℃，时间 2 。5h ，CO2 流量 2 5kg/h。

This study considers the effects of ventilation system using the residential facilities to the transmission mechanism of indoor aerosol in the residential quarantine period space for infective diseases. This study focuses on the effect of the design of ventilation system on the internal flow field and the removal of contaminant pollution. A computational fluid dynamics software-FLUENT 6.2 is employed to simulate the internal airflow field of the residential quarantine period space. The Carbon dioxide (CO2) is adopted as the index of contaminant source. Three layouts of ventilation system are simulated and the airspeed field, the temperature distribution, and the contaminant distribution are analyzed to find the best ventilation system for the residential quarantine period space.

本研究考虑传染性疾病在居家隔离空间使用一般家用环境控制设备时对室内的气悬感染会有何影响，本文主要分析不同通风设计时对居家隔离空间内部气流之影响，并将国内外现有的规范设计方式做一系列之比较以供参考，并以商用套装软体FLUENT6.2分析居家隔离空间内部流场分布情形，模拟中以二氧化碳（CO2）作为病患所呼出含有病菌空气的指标，模拟案例分为三种主要的通风模式，并分析速度、温度与污染物浓度分布情形，以得到最佳的居家隔离空间通风配置方式。
