Based on practice, treatment technology such as increasing oxygen at stove gate, sprinkling at end stove, can realize the treatment aim.

通过实践，采用炉头增氧，尾部喷淋的治理工艺可以达到好的治理效果，而且投资少，工期短，运行费用低，易于操作。

Pem gene is expressed in a time and stage specific manner. Pem transcripts are detectable as early as day 6 in mouse embryonic development, and are abundant in day 7 and 8, but decrease precipitously thereafter. Although Pem transcripts are not detectable in most of adult tissues, they are present in reproductive system. Furthermore, Pem has also shown to be specifically expressed in the proximal cauda and distal corpus regions of the epididymis, the regions where spermatozoa gain forward motility and fertilization competence.

Pem基因的表达具有明显的时间和空间特异性：在鼠胚发育的第6天，即可检测到Pem转录本的表达；第7-8天，Pem表达量达到最高，随后迅速减少；Pem基因在成年组织中一般不表达，但可在生殖组织表达；另外，Pem特异地在附睾近侧尾部和远侧的体部中表达，此处是精子获得运动性和受精能力的地方。

While we pay attention to the convergence rate towards stationary distribution, many scholars study the stochastic stability in others way, that is the tail behavior of the stationary distribution, and have got many good results.

人们在关注收敛速度的同时，又有许多学者从另外一个角度研究其稳定性，即平稳分布的尾部性质，且已得出许多很好的结果。

In this case, it is not the frame that folds from the middle, rather the steering column and the rear part that are folded down.

在这种情况下，这不是框架褶皱来自中东，而驾驶杆和尾部有折叠下来。

Since VaR method is absent of general subadditivity and description to tail information, a new risk measure framework is proposed in recent years, it is coherent risk measure.

由于VaR不具有普遍的次可加性和缺乏对尾部信息的描述，近几年来，学术界提出了新的风险度量框架——一致性风险度量，并在这种框架下，发展了多种风险度量技术，谱风险测度便是其中之一。

Under the influence of the submergence the turbulence intensity are quite high at the end stage of burning.
