查询词典 tensile strain

The results indicate that both the precipitates produced by Leptospirillum ferriphium strain DY and Acidirhiobacillus ferrooxidans strain GF are composed of jarosite and ammonium jarosite. However, the content of jarosite in the precipitates synthesized by strain GF is 5.53% higher than that synthesized by strain DY, but the content of ammonium jarosite in the precipitates synthesized by strain DY is 15.24% higher than that synthesized by strain GF.

结果表明：无论是嗜铁钩端螺旋菌DY菌株，还是嗜酸氧化亚铁硫杆菌GF菌株合成的沉淀都是黄钾铁矾和黄铵铁矾的混合物；其中，GF合成的沉淀混合物中黄钾铁矾的含量比DY合成的黄钾铁矾约高出5.53%；而DY合成的沉淀中，黄铵铁矾的含量比GF合成的沉淀中的黄铵铁矾的含量约高出15.24%。

Both of the thermophiles were motile by means of lophotrichous flagella and had high growth rate on medium containing cellulose. Optimal growth occured at 60℃ for the two thermophiles and at PH 7. 5 for Y, PH 7. 37. 5 for W strain. Y strain produced yellow pigment in cellulose medium and had yellow-colored, round or watery colonies in cellulose agar. The colonies of W strain were white -colored and similar in form to that of Y strain. The mesophile, Clostridium sp. B, was motile with peritrichous flagella. The colonies grown on cellulose agar were white and round with slightly undulate margins. The optimal growth temperature and PH of B strain were 40℃ and 7. 0-7. 2, respectively. All of the three Clostridia fermented varieties of carbohydrates and in cellulose media produced the similar end-products: CO〓H〓, ethanol and acetic acid. The DNA compositions were 34 mol% for Y and B, 35 mol% for W strain.

Among them strain MZ1 had been confirmed a lysogenic strain by indicator strain ZK1 after producing phage plaques induced by Mitomycin C.Two templates of overnight cultivation and its DNA from strain MZ1 were then amplified in the same time with five pairs of primers designed from the same phage,and the same products were obtained,suggesting that strain MZ1 was also confirmed a lysogenic strain by PCR method.

MZ1菌株的过夜培养液与指示菌ZK1(血清型H25)混匀并在双层琼脂上培养12 h后出现了滴度为2×107 pfu的噬菌斑，从而证明生产菌株MZ1确为溶原菌；又以GIL01同源性较高的其它四个基因设计引物，分别以MZ1的培养物及其溶原性噬菌体基因组为模板进行PCR扩增，结果两者得到几乎一致的带型，进一步证明了生产菌株MZ1为溶原菌，说明利用PCR法检测鉴定苏云金杆菌的溶原性是可行的。

In the case of granite, observation results indicate that the extending routes of active cracks are mainly intercrystalline, transcrystalline, inter-transcrystalline, and intracrystalline. When the strain rate is low, the long intercrystalline cracks are prevailing, and with increasing of the strain rate, the short transcrystalline and intracrystalline cracks gradually increase. The statistic results show that the active crack density increases with increasing of the strain rate, and the mean length of active cracks diminishes with increasing of the strain rate, that is, the induced damage in comminuted product increases with increasing of the strain rate. For the first time this dissertation integrates macroscopic results of comminution with active crack growth under impact loading. It elucidates why the dynamic comminution strength of mineral beds increases with increasing of the strain rate through the active crack extending, and analyzes the influence of structure and constitution of minerals on their damage under impact stress. It is authenticated that both the size distribution and the damage population of comminuted product can be characterized by the fractal.

为分析料层颗粒在冲击下的细观损伤效果，采用德国生产的ASM68K半自动图象分析仪对粉碎生成物中的损伤情形进行了观测，以花岗岩为例，观测结果表明花岗岩颗粒在冲击应力下的活化裂纹扩展路径主要表现为沿晶、穿晶、沿穿晶和晶内等形式，在低应变速率下，活化裂纹以沿晶裂纹较多，随着应变速率的提高，其它裂纹形式大量繁衍，统计结果表明活化裂纹密度随着应变速率的增大而增大，活化裂纹的平均长度随着应变速率的增大而减小，综合表现为颗粒的细观损伤程度随着应变速率的增大而增大；首次将应力作用下的活化裂纹演化特征与粉碎的宏观效果相联系，并就料层动态粉碎强度随应变速率增大而提高的现象从裂纹演化特征的角度进行了解释；分析了矿岩构造结构特性对损伤产生和分布的影响。

The results show that the mechanical properties of this PMMA depend strongly on the testing temperature. The Young's modulus and flow stress were found to decrease with increasing temperature at low strain rate. At the strain rate of 10^(-1) 1/s, strain soften was observed under all experiment temperatures. At high strain rate, with the temperature increase, the flow stress deceases remarkably while the failure strain increases, and the strain softening was also observed at the temperature above 333K.

试验结果表明：在准静态载荷下，随着温度的升高，材料的弹性模量和流动应力减小，在应变率为10^(-1) 1/s时表现出明显的应变软化行为；在高应变率(550 1/s)下，随着温度的升高，材料的流动应力逐渐减小而破坏应变增大，当温度超过333K时也有应变软化现象发生；在相同温度下，随着应变率的升高，材料的流动应力增大，但破坏应变减小。

The results show that though the strain is growing slower in the nitrogen-free medium than in the nitrogen-containing medium, the content of capsular polysaccharides produced by the strain in the nitrogen-free medium is higher than those in the nitrogen-containing medium, the content of capsular polysaccharides produced by the strain in the nitrogen-free medium is higher than those in the nitrogen-containing medium. The capsular polysaccharides produced by the strain in the culture which contains different mineral powders will reach the highest content on the third or the fourth day in its growing period. The strain's capability of releasing potassium from k-feldspar and biotite in the nitrogen-containing medium is higher than that in the nitrogen-free medium because in the nitrogen-free medium, the strain and its production of glucoprotein are less than those in the nitrogen-containing medium.

结果表明，尽管该菌在无氮培养条件下的菌体数量远小于有氮培养条件，但无氮培养条件下所提取的细菌多糖多于在有氮条件下培养所提取的细菌多糖；胶质芽孢杆菌在以添加钾长石粉或黑云母粉制作的无氮培养基中生长可形成大量多糖，采用丙酮法进行细菌培养液多糖提取，发现细菌培养的第3天所提多糖含量最高；胶质芽孢杆菌在以添加钾长石粉或黑云母粉制作的有氮培养基中生长亦可形成较多的多糖，且在细菌培养的第4天所提多糖含量最高；胶质芽孢杆菌在有氮条件下对含钾矿物的释钾率高于在无氮条件下的释钾率，这可能与该菌在有氮条件下生长更快、可产生较多菌体细胞有关。

Experiments were conducted for testing root tensile strength and measuring root cellulose content of Medicago sativa and Digitaria sanguinalis. Results indicated that in the two species, both the tensile strength and percentage of cellulose were negatively correlated with root diameter, while a positive correlation was found between percentage of cellulose and tensile strength. The conclusion confirmed that the relationship among root tensile strength, root diameter and root cellulose content found in tree root system was held also in the two species.
