yielding strain
解釋
永久應變-
In the early 1970s, he succeeded in developing three strains of hybrid rice, namely male sterile, maintainer and restorer, and obtained the world s first high - yielding hybrid rice strain. he is the first scientist who successfully altered the self - pollinating characteristic of rice and made large - scale farming of hybrid rice possible. this earned him the title " father of hybrid rice "
七十年代初，袁教授成功實現了雜交水稻的不育系、保持系及恢復系三系配套，首次育出雜交水稻；他又打破世界的自花授粉作物育種的禁區，並實現了大面積種植雜交水稻的可能，為他在國際上贏得雜交水稻之父的美譽。 -
The results showed that yielding the strength increase with the strain rate, the energy absorption increase with increasing strain rate and was related to the density. strain has slightly effect on the strain rate sensitivity of the solid material, but the strain rate sensitivity of fs increase with increasing true strain and also increase with incremental change in strain rate at the same true strain. the properties of thermal conductivity, electrical conductivity and electromagnetic shielding were studied
實驗結果表明，泡沫鋁的屈服強度隨著應變率的增加而增加；應變對固體材料的應變率敏感度影響很小，但是泡沫鋁的應變率敏感度不是常數，而是隨著真應變的增加而增大，在同樣的應變下，隨著應變率變化幅度的增大而增大；泡沫鋁的能量吸收隨著應變率的增加而增加並且和泡沫鋁的密度有關；泡沫鋁的吸能效率隨著應變率的增加略有下降。 -
A pair of primers were designed and synthesized based on the published ge gene sequence of prv - rice strain for amplifying ge gene of prv min - a, yielding a 1. 7kb band. the segment was linked to puc19 plasma dna by means of t4 dna ligase, transformed into e. coli jm109 permissive cells, and incubated on lb fray containg amp, x - gal and iptg. small amount of plasma was extracted by base cleavaging for enzyme digest analysis and pcr, resulting in recombinant plasma puge dna containing prv ge
用t _ 4dna連接酶使ge基因與經bamhi 、 kpni同樣雙酶切的puc19質粒dna連接；用連接產物轉化大腸桿菌jml09感受態細胞，置含amp 、 x - gal和iptg的lb平板上培養12 20小時；挑取白色菌落於選擇性培養基擴大培養，堿裂解法小量提取質粒dna ，並進行酶切分析鑒定，結果獲得整合有prvge基因的重組質粒pugedna ，並與其它prv分離株進行ge基因序列同源性分析。 -
In order to enhance the trehalose production, y7 was used for mutation with ems. through primary screening and compound screening, strain l61 with high - yielding trehalose and deep neutral trehalase activity was screened
實驗對出發菌株y7進行了ems誘變處理，通過初篩、復篩，從中選育出一株能高產海藻糖同時具有較低海藻糖分解酶活性的菌株l61 。 -
Over 521 strains were screened for phytase production from 30 kinds of soil samples. out of them, four strains were obtained by the primary screening, then, one strain ( lw03 ), which has higher levels phytase production, was screened by enzyme yielding tests. lw03 strain was primarily identified to be rhizopus
以lw03為出發菌株經紫外線、 des 、 co ~ （ 60 ）射線和ntg等連續誘變及篩選，得到1株植酸酶高產菌株no13 ，並對根霉no13菌株固態產酶條件、部分酶學性質及其在米糠、菜籽粕植酸體外降解試驗進行了研究。 -
For metals that experience the gradual elastic - plastic transition, the point of yielding is determined as the initial departure from linearity of the stress - strain curve and this is sometimes called the proportional limit
對于金屬逐步的彈塑性形變轉變，其屈服點確定為應力應變曲線非線性關系的開始，這個點也被稱為比例極限。 -
The dynamic plastic response for a pinned rigid plastic beam subjected to an arbitrary impulsive distributed load was investigated. the effect of strain hardening and strain rate sensitivity was ignored. the yielding curve was assumed to be rectangular
採用剛塑性假定，忽略應變強化效應和應變率的效應並考慮由於有限變形而導致的軸力的影響，研究任意時間歷程沖擊載荷作用下簡支梁的塑性動力響應問題。
