查询词典 poor gas

Comparing with Galaxy, M31 has much lower gas and SFR profiles, but their total dynamic: mass are comparable. That means M31 needs faster star formation rate and infall rate (namely shorter infall time scale) in order to consume more gas . However, the low nietallicity and flat abundance gradient require lower star formation efficiency, and few metal poor stars means the infall time scale can not be very short.

与银河系相比，M31有着较低的气体轮廓及SFR轮廓，但其动力学总质量与银河系相当，这便要求有较大的SFR及较快的下落速度来消耗更多的气体；然而，较低的金属丰度及丰度梯度意味着SFE不能过高，贫金属星很少又暗示着下落时标不能很短。

Especially for structured packed columns, which are boomingly used, due to the poor self-distributivity resulted from the lower pressure drop of the structured packing, and the more sensitivity to gas distribution, the influence of gas distribution for structured packed columns is more severe.

特别是目前逐渐被广泛应用的规整填料塔，由于其阻力小，对气体得自分布性能较差，同时有对气体的分布较为敏感，所以气体分布状况会对整个精馏塔的分离效率有较大的影响。

Combined with investigation results of the furnace body erosion before relining, this paper analyzes the cause of production problems appeared in the first campaign life of the blast furnaces. Because of the existence of design shortcomings in large cooling block and bosh cooling stave, it resulted in poor furnace performance, such as stronger peripheral gas flow and irregular profile. The quick rise of bottom temperature of No.7 BF was caused by the penetration of molten iron into the joint of bottom carbon block, wheresas the quick rise of bottom temperature of No.6 BF was due to gas fleeing through the furnace bottom.

一位资深的发展商认为，以前的物业管理很难深入到每家每户，尤其是大型社区，水费、电费、煤气都得上门抄表、收费，社区安全包括防盗、煤气泄漏、急救等都是棘手的问题，社区的文化、娱乐生活缺乏业主与物业管理方的交流，因而显得单调贫乏。

The results showed that the contact of gas and liquid was poor with gas distributor of one loop.

单环分布器产生的气液两相接触效果较差，对于反应过程很不利。

The disadvantages such as high exit gas temperature, poor CO 2 reduction and high gas velocity are the consequence of the design.

如高出口气体温度，差的缺点有限公司 2 减少和高气速是设计的结果。

The feasibility of the relevant technical method is discussed to the problems such as lower heating value of the coal gas, the poor comprehensive use of the coal gas and so on.

针对现行低温干馏工艺存在的煤气热值低、煤气未完全回收综合利用等问题，讨论了相关技术措施的可行性。
