正起作用的

The rhythm of the work song of the boatman in Xiajiang is brisker , it is not outstanding that the power of the beat is compared with, to is it count comparatively flexible to take small matter, present repeated dense wave type move forward constantly, melody change range to be relatively little.

在这样的集体体力劳动过程中，船工号子主要起统一步伐、统一意志、鼓舞情绪的作用。如果没有这类歌声来激发船夫们的斗志，统一步伐，那么是很难渡过险滩的。船工们唱起号子来了，就忘了疲劳，正所谓"不喊号子不起劲，打起号子抖精神"。

In DMMCS, there is an alternative distribution of inertial instability column and inertial stability column, at the west and south, there lie negative CVV columns, while negative CVV column is beneficial to deep moist convection.(4) The strong slantwise convection induced by inertial instability, baroclinic instability and conditional symmetry instability will enhance the upper level southerly component. Because of the appearance of the compensated downdraft at the low level of the south side of DMMCS, the low level southerly is intensified, the enhancement of upper- and low-level cores are in favor of the development of DMMCS. And that will do favor for the reinforcement and maintenance of inertial instability, baroclinic instability and conditional symmetry instability, it is a positive feedback process.

深湿对流系统中高层西侧为负MPV2 柱，东侧为正MPV2 柱；(3)深湿对流系统中惯性不稳定柱与惯性稳定柱相间分布，西侧为负CVV 柱，东侧为正CVV 柱，负CVV 柱对深湿对流起激发作用；（4）惯性不稳定、湿倾斜不稳定和条件不稳定产生强的倾斜式对流，而强的倾斜式上升运动加强了深对流系统北侧高层的南风分量，因深对流系统南侧低层出现补偿性下沉气流，因而低层南风加强，高低空急流中心的加强会进一步加强对流的发展，使得惯性不稳定、湿倾斜不稳定和条件不稳定增强和维持，这是一个正反馈过程。

During the cormels growth, the contents of sucrose, starch and cellulose, with positive correlations with LOX-1 activity, showed different increase in corm and cormels, which also suggested that sucrose, starch and cellulose played important roles in the formation and enlargement of gladiolus corms and cormels.

在唐菖蒲籽球生长发育过程中，新球和籽球中蔗糖、淀粉和纤维素含量都不同程度升高，并且与LOX-1活性呈正相关，说明蔗糖、淀粉和纤维素对唐菖蒲新球和籽球的形成和膨大起着重要作用。

Furthermore, the NBO calculation implies that relative stabilities of all 15 conformers can be attributed to the steric and hyperconjugation effects. In addition, the result derived from G3MP2 shows that the heats of formation of all conformers are positive and heats of formation of ring conformers are greater than those of chain conformers.

而且，NBO的立体和超共轭分析表明立体交换排斥能和超共轭作用对这些分子的相对稳定性起了重要作用。G3MP2计算结果表明氮氢化合物的生成热均为正，并且环状分子的能量和生成热都高于链状分子。

Based on a dynamic analysis of that model we found the cause that leads to the system long phase rise and fall , and we proved the undulatory inevitability of the system .

经济长波的上升阶段从长期来看，是由于经济系统内的这两个客观事物在总体上的相互"正作用——相互促进"起主导作用所导致的。

Different additives acted differently in the course of fermentation. Dodecane as oxygen vector and cosolvent, Tween-85 as surfactants and structure analog of carbon source, were the most important for the lipase production.

不同的添加剂在发酵的过程中所起的作用不同，正十二烷作为氧载体和溶剂的作用，Tween-85作为表面活性剂和碳源结构类似物的诱导作用，在发酵过程中对脂肪酶能够大量的产生都是至关重要的。

The results of correlation and regression analysis of the questionnaire data were as follows: external locus of control and higher SDO level were negatively related to the use of integrating conflict management style; organizational justice was positively related to the use of integrating conflict management style; the negative relation between internal-external locus of control and integrating conflict management style could be intermediated by informational justice partially; the negative relation between SDO level and integrating conflict management style could be intermediated by organizational justice completely.

对研究数据的相关和回归分析得出以下结论：外控倾向、高社会支配取向与员工对上级使用整合的冲突处理方式负相关；组织公平与员工对上级使用整合的冲突处理方式正相关；信息公平对内外控与整合处理方式的负相关关系起部分中介作用；组织公平对社会支配取向与整合处理方式的负相关关系起完全中介作用。

This study will contribute to a better understanding of mechanism of bone remodeling during tooth movement which may set the basis for clinical work. Methods1. Observe the expression of ATF4 protein in periodontal tissues after orthodontictooth movementA titanium-nickel closed-coil spring was applied to the occlusal surface of the rat maxillary first molar (M1) with a hook and the upper incisors with a ligature wire.

但正畸骨改建与骨发育是两种不同的生理过程，ATF4在正畸牙齿移动牙周组织的表达和分布，在机械力的作用下体外培养的人牙周膜细胞中表达变化的情况，以及在牙周膜细胞向成骨样细胞分化的过程中所起的作用，国内外尚未有报道。

These results suggested that adrenal corticoids play an important role in maintaining sympathetic tone on the central cardiovascular regulation and basal BP, and that the enhancement of cardiovascular activities produced by adrenal corticoids may be one of the important causes in the incidence of stress-induced hypertension.

提示肾上腺皮质激素在维持中枢性心血管交感紧张性和正常血压中起正性调节作用，并提示有可能肾上腺皮质激素在rVLM心血管活动的加强作用为应激致高血压发病机制中的重要环节之一。

Corresponding to the long-lasting El Nio event, cyclonic anomalous circulation over the eastern North Pacific weakens slowly and anticyclonic anomalous circulation over the western North Pacific strengthens slowly at 850 hPa. Therefore the tropical Pacific westerly anomaly keeps long. The anomalous positive velocity potential over the western South Pacific at 200 hPa, which is related to the strong Australian winter monsoon, helps a long duration of El Nio. Corresponding to the short-lasting El Nio, the anomalous positive velocity potential over the western Pacific at 200 hPa moves eastward quickly and results in the vanishing of El Nio event.

还发现对于持续时间较长的El Nio事件，东北太平洋上850hPa异常气旋性环流减弱和西北太平洋上异常反气旋性环流增强较慢，因此赤道太平洋异常西风维持的时间也较长，而与澳大利亚冬季风加强相关联的南半球西太平洋的速度势正距平的维持，对El Nio的持续也起一定作用；对应持续时间较短的El Nio事件，西太平洋上200hPa速度势正距平的迅速东移，对El Nio的迅速消亡起重要作用。
