The specific discharge at such a point is infinite . 此種點(diǎn)上的比流量為無(wú)窮大。
Plant a tree , pull weeds , or get your hands dirty 種點(diǎn)樹,拔點(diǎn)草,不要讓手閑著。
" we wanted to plant some flowers there , she cried “我們想在那里種點(diǎn)花。 ”她喊著。
Yeah , i mean , you could grow stuff if you want 是啊,我懂了,就是說(shuō),如果你愿意的話可以自己種點(diǎn)什么東西. .
He dug ditches during the week and on weekend he and grandma dug a garden to grow some of their own food 在平時(shí)他挖溝渠,周末和奶奶在花園里挖挖鋤鋤,種點(diǎn)自己的糧食。
At the same time , the values " range of two kinds of nonsquare constants and their values in real inner product space are given . we also discuss the pointwise nonsquare constant in finite dimensional f space 同時(shí)給出了兩種點(diǎn)態(tài)非方常數(shù)的取值范圍,和實(shí)內(nèi)積空間中兩種點(diǎn)態(tài)非方常數(shù)的值。討論了有限維l ~ p空間的點(diǎn)態(tài)非方常數(shù)。
Our work elucidates the formation of the feedback inhibition site . point mutations reveal that amino acid replacements at phel44 , leul75 , leul79 , phe209 and val221 partially or completely relieve the feedback inhibition of arog addressed by 1 mm phenylalanine . combined with the 3d structure of arog , our results demonstrate that the feedback inhibition site consists of asp6 , asp7 , ile10 , ile13 , pro150 , gln151 , leul75 , leu179 , serl80 , phe209 , ser211and val221 實(shí)驗(yàn)結(jié)果表明:在1mm苯丙氨酸的存在下, 1 )野生型arog受到90以上的反饋抑制; 2 ) pro150leu , leu179ala , phe209ala和val221ala這四種點(diǎn)突變?cè)诒3峙c野生型arog相近的比活的同時(shí),解除了80 100的反饋抑制; 3 )點(diǎn)突變phe144ala僅解除反饋抑制約30 ,同時(shí)保持與野生型相當(dāng)?shù)谋然睿?4 )突變體leu175ala僅能夠解除18的反饋抑制, leul75gln能夠解除44的反饋抑制, leu175asp解除了84的反饋抑制,并且比活都比野生型高。
