查询词典 proof stress

We also found that the content of Na(superscript +), K(superscript +) and proline in leaves varied with different treated days. Under all treatments, the absorption of Na(superscript +) increased and the content of proline in leaves decreased with the prolonging of treated days. The absorption of K(superscript +) measured on the 7th day and the 21st day increased and was restrained on the 14th day, which lead to the decline of K(superscript +)/Na(superscript +) ratio. While the content of praline measured on the 14th day remarkably increased with the increase of salinity. Our experiment indicated the live oak seems to adapt the salt stress by increasing the absorption of K(superscript +) during the earliest and late stages of salt stress and accumulating proline in leaves during the middle stage of salt stress.

同时发现，盐胁迫处理不同时期对叶片脯氨酸含量和Na、K含量的影响各不相同，在处理7d和21d时，叶片对Na和K的吸收量均有增加，使K/Na维持相对稳定的比值，而脯氨酸含量随NaCl质量质量浓度的增加减少；在处理第14d时，对Na吸收增加的同时，抑制了对K的吸收，导致K/Na比值随NaCl质量质量浓度的增加而迅速下降，而此时叶片脯氨酸含量随着盐质量质量浓度的增加而迅速增加，表明在盐胁迫早期和晚期，弗栎可能通过增加对K的吸收以减轻Na离子毒害效应，而在盐胁迫中期，叶片积累脯氨酸是适应盐胁迫的方式之。

During the course of water stress, along with the extension of coercion and the intimidation of the deepening,the Pn of P.euphratica and P.pruinosa experienced three phases:sharp decline-slow, rebound -down and again under moderate and serious stress condition.16 and 24 days later after water stress starting,the reason of Pn drops mainly is the stomatal limit,and 48 days later,primarily is non-sto matal limit.

最后，本文采用离散模型研究了各向异性材料主微裂纹干涉问题中T应力对主裂尖应力强度因子的影响：T应力对主裂尖应力强度因子的影响是不能被忽视的，这种影响不但与微裂纹的几何分布有关，而且还与T应力的大小和符号有关。

At the same time, the MEMS geophone can be used to monitor the microseismic event of coal mining, water reservoir and hydraulic fracturing through the research of failure location and the ratio of rock fracture can be predicted by counting numbers of acoustic emission.After spent six months to monitor injecting microseism in Ying 11 block of DongXin field using this system and collect abundant microseismic wave files. The result showed that the orientation of injecting fracture was mainly NE90°to NE125°. The maximum horizontal principal stress directions were mainly distributed in NE90°-NE130°range. Analysis of numerical simulation result of reservoir stress in Ying 11 block showed that the maximum horizontal principal stress directions are approximate east-west in central and western region and approximate NE130°at eastern border.

利用该系统对东辛油田营11进行了六个月现场注水微震监测，对监测数据的处理表明营11注水区域裂缝发育方向基本上为NE90°-NE125°；同时营11地区油藏地应力数值模拟结果分析表明其水平最大主应力的方向主要分布在NE90°-NE130°的范围内，研究范围中西北区块的水平最大主应力方向近似为东西向，研究区块的东部边界的水平最大主应力方向近似为NE130°左右，模拟结果与裂缝监测方位相符较好，两者结合给出了这个地区合理开发部署建议。

From monomial mensurated results, we can see that the sequences of the low temperature stress tolerance of several lines are different, but the low temperature stress tolerance of some lines is steady, such as 24, 14 and etc, So we can account for the trend of the low temperature stress tolerance of lines.

在上述各单项指标测定结果间比较可以看出，部分品系耐低温能力在排序中位次有一定差异，但其中有一些品系的耐低温能力总体上还是比较稳定的（如24、14等），可以说明耐低温能力的趋势。

Stress is a relative notion; only words with two or more syllable can be said to have word stress, and monosyllabic words, can not be said to have word stress.

重音是一个相对的概念，只有两个或两个音节以上的单词才可以说有单词重音，单音节的单词，即只有一个音节的单词，是不可能有单词重音的。
