查询词典 inertia group

Firstly, the transient stability of the modes by which some kinds of huge power suppliers are connected with AC power grid is analyzed and compared in detail; then a detailed transient stability simulation of a certain large-scale demonstration system is performed; finally some helpful conclusions are obtained: in the general situation, the bundling power transmission mode is favorable to increase the stability of sending system; if it is helpful to evidently increase the inertia of the equivalent leading group, the mode that connects the huge power supplier with sending system will be helpful to enhance the stability of sending system, however it is necessary to perform simulation and analysis while these principles are applied to FACT systems.

首先从机制上对几种大电源接入交流系统方式的暂态稳定性进行了详细的分析和比较；然后对大型算例系统进行了详尽的暂态稳定仿真；最终得出了一些有用的结论：一般情况下，打捆送电方式有利于提高送出系统的稳定性；如果有助于显著增加领前群的惯量，则与送端系统相联的方式也有助于提高送电系统的稳定性，但仍要结合具体系统进行分析。

However, during New Trend '85, Gu Wenda differentiated himself from most artists of Chinese Painting of the time and showed his contemporary consciousness by experimenting on traditional ink painting materials and techniques. This brought out a new possibility for the contemporaneity of Chinese Painting. Since then, unremitting efforts have been made to "modernize" Chinese Painting through traditional abstract elements like ink-wash and Calligraphy. These efforts streamed into a new trend called "modern ink"(or "abstract ink","experimental ink") in late 1980's, though seemed not widely acknowledged for its resemblance to Abstract Expressionism of 1960's and 1970's American art. What is interesting is that while some artists are endeavoring to "westernize" their art, a new trend grouped as "Neo-literati Painting" appears with very traditional form and mood. This can be explained as a group of people's resistance to the reformation of traditional culture as well as their nostalgia to traditional ideals. However, this school tends to be artificial for the absence of the particular context, and the expression with traditional brushwork is also regionally limited. Of all the efforts of reformation, Chinese Painting that accordingly adopts the tradition heads the list because of the cultural identification of the big number of population and greater market as a result of the economic growth of China. Meanwhile, the immense conservative inertia of traditional Chinese culture can also be detected.

在"现代艺术"风起云涌的"85新潮"中，谷文达以传统水墨的材料和方法表达出不同于当时大多数中国画艺术家们这种文化心态和文化认知的现代意识，为中国画的现代性提供了一种方案；以水墨、还有选择中国传统书法的抽象因素等可能来进行现代性探索，一直是中国画连绵的努力，在80年代后期汇聚成"现代水墨"（又或曰"抽象水墨"、"实验水墨"），是中国画的又一流向，但是不是没有脱离60、70年代美国的"抽象主义"意义，反而还有了拾人牙慧之嫌，所以始终难以获得更大的认可和成功；很有趣的是，与此"西化"流向同时的，还有以非常传统的方式出现的"新文人画"潮流，或许可以把这看着是部分中国文化人在中国以西方为参照的新文化背景下对之的抵制，对传统理想的怀念和诉求，但由于已经失去了其语境和环境，"新文人画"显得娇情和造作，而且这种以非常地域化的传统笔墨语言来表现的方式也失去了更为普遍化的可能；反而是延续传统一脉的国画，由于有巨大的人数基础的本土文化的认同，在中国经济发展后有了更大的市场，所以还是蔚然为中国画的一大潮向，从这也可以看到中国文化承传的保守性的力量。

Evidence suggests that 1 under more stable stratification, the basic flow, if moving faster at low and high levels (particularly in the presence of jets there), allows a resulting meso-β unsteady wave to propagate eastward with respect to basic flow and even at greater velocity compared with it; 2 vertical windspeed shear of basic flow causes instabilities of the TWT perturbation; 3 considering the second derivative of basic-flow wind with respect to z (denoted by zz≠ 0 which is simply given as β* hereafter) the expression for the phase velocity of vortex Rossby wave is obtained, which is unidirectional in propagation with respect to basic flow; 4 VRoW has its physical origin from β*, i.e., from z-varying heterogeneities of y-direction averaged vorticity of the basic flow field; 5 VRoW phase velocity is associated with zonal wave number k, its energy is dispersive and the group velocity exists in the x direction; 6 when windspeed meets the condition of β*, TWT disturbance instability may be that of mixed VRoW and gravity wave; 7 if basic flow is subject to linear shear but does not meet the condition of β*, the TWT instability is that of inertia-gravity wave.

在大气层结比较稳定的情况下，如果基本气流在低层和高层较大(有可能存在低空急流和高空急流)，此时产生的β中尺度不稳定扰动相对于基流向东传播，甚至于快速向东传播。基本气流在垂直方向上的风速切变对于中尺度横波型的扰动起着不稳定的作用。如果考虑基流的二次切变，可以得到涡旋Rossby波的相速度表达式，涡旋Rossby波相对于基本气流是单向传播的。涡旋Rossby波产生的物理根源是基本流场的风速二次切变，亦即基本流场y方向的平均涡度在空间z方向上的不均匀所致。涡旋Rossby波的相速度与纬向波数也有关，它的能量是频散的，其在纬向x方向也存在群速度。在基本流场的风速存在二次切变时，横波型不稳定可能是混合的涡旋Rossby重力波的不稳定；而在基本流场的风速仅仅存在线性切变，不存在二次切变时，横波型扰动的不稳定则是重力惯性波的不稳定。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
