变幅

The ventilation rete doesn′t hold a constant level,and its varying is irregular.

在本研究中，排气量并未始终保持在一个稳定的水平上，其变幅较大且无甚规律可循。

A constitutive model was developed on the base of Ohno–Wang kinematic hardening model Int. J. Plast. 9 (1993 375, 391. In the developed model, the rate dependence of the material was reflected by a viscous term; the steady cyclic flow was reflected by the evolution of kinematic hardening rules with critical state of dynamic recovery developed by Ohno and Wang Int. J. Plast. 9 (1993 375, 391; the cyclic hardening was only characterized by the evolution of isotropic hardening and an evolution rule of isotropic hardening with a term of dynamic recovery was used; the effect of loading history on the ratcheting was also considered by introducing a fading memorization function for maximum plastic strain amplitude into the model.

基于Ohno-Wang模型建立了一个新的、考虑材料的率相关特性的本构模型，模型中通过具有临界面的随动硬化律来反映稳态的循环流动，并通过带动态恢复项的各向同性硬化演化率来反映循环硬化的影响以及采用最大塑性应变幅值的衰减记忆函数来反映棘轮行为的加载历史记忆效应。

The organic matter decreased in Autumn and reached to a valley in Winter, then it raised to the peak in Summer and Autumn; the total N fluctuated which change range is smaller than 5%; the soil NHt+-N rose firstly, reduced in Autumn and Winter, then rose in Spring; additionally, its peak appeared in Summer and valley in Winter; the soil NCV-N"s change was more complicated than NHU+-N and fluctuated with season whose peak appeared in rain season; the available N"s change tendency was similar to NH4+-N, it decreased in May; the hydrolysable N fluctuated in smaller range, and its content decreased steadily and showed no apparent peak in a year.

有机质含量秋季下降，冬季下降到低谷，随后逐步回升，夏、秋季达到最高水平；全氮的时间动态仅为小幅度的波动，变幅不足5％。铵态氮的变化趋势为：升高—降低—升高，高峰期出现在夏季，低峰期则出现在冬季；硝态氮的时间变化比铵态氮复杂，呈明显的波浪式起伏变化，最高峰出现在雨季；速效氮的时间变化与铵态氮类似，5月出现明显低谷；水解氮表现为小幅度的不规则波动，总的走势为平稳下降，全年没有明显高峰。

For example, the micro biomasses are higher and change fiercely in the ridge or furrow soil of the no-tillage and ridge culture treatment while keep lower and change less during the measured year in soil of conventional tillage treatment and no-tillage and fallow in winter treatment.

如垄作免耕的微生物生物量数值无论在下层或上层土壤中均较高。常规耕作、冬水免耕处理全年的微生物生物量量及变幅均较小。

The quantificational correlations between summer and winter monsoon intensity reflected by annual monsoon amplitude were the fixed proxy of monsoon variations of dry and humid.

季风年变幅反映的夏季风与冬季风强度的定量组合关系，是季风气候干湿变化的定量代用指标。

Including the turntable, Renzi Jia, varying from pulley blocks; off part of the frame, including track and frame (track gauge change will require aircraft to transport state); and arm at the end of the main section arm, the total vehicle weight control in less than 45 tons.

包括转台、人字架、变幅滑轮组；下车部分包括车架和履带架（履带架要求将轨距变到运输状态）；以及主臂底节臂，整车总重控制在45吨以内。

Soil organic matter was high in Baoshan tobacco-growing areas and ranged from 1.50 g/kg to 148.10 g/kg with a mean of (32.43±12.38) g/kg and variation coefficient of 33.34%.

保山烟区土壤有机质含量较丰富，平均为(32.43±12.38)g/kg，变幅为1.50~148.10 g/kg，存在广泛的变异，其变异系数达33.34%。

Duration of inversion temperature near ground surface is longer, air temperature is lower, air humidity is higher and water surface evaporation of 20cm standard pan on the top of canopy is generally lower under sprinkler irrigation condition than those under surface irrigation condition.

喷灌跟地面灌溉相比，喷灌条件下近地面出现的逆温时间长，空气温度低，离地面1～4米高度范围内空气湿度大；冠层顶部20cm蒸发皿水面蒸发量小；喷灌条件下0～60cm土层内土壤含水量较高且变幅较小，白天地表温度低，晚上地表温度高。

The occurrence percentage of GAB in surficial layer of sediment was higher than that in the other layers. The occurrence percentage, abundance and its variation of GAB in Bering Sea were higher than that in the Chukchi Sea respectively.

结果表明，水中GAB检出率大于沉积物，但丰度仅为后者的 0 。0 7%；表层沉积物中GAB检出率高于其它层次；白令海GAB检出率、丰度及变幅均高于楚科奇海。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。
