Let μ be a smooth measure with a quasi regular Dirichlet form, A μ be its non negative additive functional,and U α A μ be the α Potential operator of A μ.

设μ是拟正则狄氏型的光滑测度,Aμ是其对应的非负连续可加泛函,UαAμ是Aμ的α位势算子,本文证明了测度μUαAμ关于μ的绝对连续性,并以R-N导数dμUαAμdμ刻划了μ具有有限能量积分的条件。

If any person B, in any imaginable situation at any time t', were warranted in believing that at an earlier time t some specified person A sincerely made the statement "My present afterimage is red," and also that A did not immediately revoke or otherwise discredit it, then B would not be warranted at t' in believing that at t A had an afterimage that was not red.

这里排除A所可能发生的"使用和表达错误",A确实有红色的余象( afterimage :视觉刺激结束后持续的图像);而且这里不仅要表明B没有证据表明A的陈述是错的,而且之所以如此是因为A的陈述意味着被描述为红的是余象而非其他,不是一个反思,不是一个玻璃杯上的红点,不是墙上的红斑。B不能矫正的不是A的陈述,而是A的余象。

That indicated the availability of SRAP technique in studying genetic variability in Arachis. Estimates of genetic distance among the 28 accessions Arachis section ranged from 0.12 to 0.75 with average genetic distance of 0.42. A genetic distance clarified that A-genome A. duranensis was most closely associated with tetraploid germplasm, which could be A-genome donors. Dendrogram of cluster analysis classified 28 accessions Arachis section into two groups: one including tetraploid germplasm, and A.

聚类分析表明,28份花生材料间的遗传距离变幅为0.12~0.75,平均为0.42,A基因组物种Arachis duranensis与栽培种花生的亲缘关系最近,可能是栽培种花生的A基因组的供体。28份种质分为两大类,第一大类包含四倍体种质及A基因组的A。

Because of the associative law for addition, we can define multiplication based on addition, a b means a+a+…+a,adding a with b times.

正是由于加法的结合律使得我们可以在加法的基础上定义乘法,就是重复加法的简便运算:a b=a+a+…+a,对a重复相加b次。

By regression analysis of the obtained data, a relationship has been found between the bath depth and ingot height, which can be expressed by an exponential function, h(0,Y)=A e-B/Y, where A is the asymptotic value of the exponential function (when Y→∞hmax=A), B is a shape coefficient of the curve.

通过对已得数据的回归处理,找出了熔池深度h及锭高Y间的相关规律,得到h_(0,Y)=A·e_的指数函数关系,A是指数方程的渐近线,当Y+∞时h_(max=A是曲线形状系数。A和B均为重熔电流的函数,A=f_1,B=f_2,所以,h_(0,Y)=f_3。

Methods The clpE-deficient strain was constructed by LFH-PCR and identified by PCR and sequencing. The impact of clpE mutant on the virulence of S. pneumoniae was evaluated in a mouse model. In addition, we also studied the effect of clpE mutant on adherence and invasion of host cells. Real time RT-PCR was used to measure the mRNA expression levels of autolysin A, pneumococcal surface adhesion A, pneumolysin, pneumococcal surface protein A and neuraminidase The clpE gene was replaced completely by erm cassette.

用长臂同源多聚酶链式反应方法失活clpE基因,用PCR、测序鉴定缺失菌株,通过动物实验观察clpE基因缺失株毒力改变情况,同时用细胞实验比较clpE基因缺失株和野生菌对宿主细胞的粘附和侵袭能力,最后用实时荧光定量PCR分析自溶素(major autolysin A,lytA)、表面黏附素A(pneumococcal surface adhesion A,psaA)、溶血素(pneumolysin,ply)、肺炎球菌表面蛋白A(pneumococcal surface protein A, pspA和神经氨酸酶(neuraminidase, nanA)的表达。

A binary relation from a set A to A is said to be a binary relation on A.

从集合A到A的二元关系,称为A上的二元关系。

To investigate the function of Nogo-A in neurons, human embryonic kidney cell line 293FT was used as a model, along with the pathway profiling reporter system to check the involvement of Nogo-A in regulating the intracellular signaling pathway. It was found that over-expression of Nogo-A could activate NF-KB signaling specifically, then followed by using different Nogo-A alternative splicing isoforms and a serial of truncations, it was confirmed that the activation of NF-kB by Nogo-A relied on its N-terminal proline rich domain. Furthermore, by co-expressing the dominant negative mutants of some NF-kB pathway associated proteins, it revealed that the IkBα,TRAF6, Rac/Cdc42 were involved in Nogo-A inducing activation of NF-kB.

为探讨神经元内Nogo-A的功能,以HEK293FT细胞为模型,利用信号途径报告基因系统筛选过表达Nogo-A对多种信号途径的调控作用,发现过表达Nogo-A能特异激活NF-kB信号,利用不同的Nogo-A剪接体和截断体形式研究,证明Nogo-A激活NF-kB信号依赖于其氨基端的proline rich结构域,进一步使用NF-KB信号途径相关分子显性突变体揭示IkBα、TRAF6、Rac/Cdc42参与Nogo-A激活NF-kB信号。

HE STARTED out as Richard A. Gekoski, a gawky American high-schooler focused only on discovering sex, and morphed into R.A. Gekoski, a fully fledged, if miserable, academic teaching English literature at a provincial British university. Only in his mid-50s, having abandoned academe and an unhappy marriage, and high-tailed it to London, did he discover who he really was: Rick Gekoski, a roly-poly book dealer with an appetite for all things big and a passion for Groucho Marx's motto:" Outside of a dog, a book is a man's best friend. Inside of a dog, it's too dark to read."

开始,他叫做理查德·A·杰柯斯基,那时他还是个上高中的傻小子,专注于探寻鱼水之乐;之后,他蜕变为R·A·杰柯斯基,一位羽翼已丰的英文文学教员,就职于一所英国地方性大学;而直到他五十五岁左右之时,在放弃了他的学术和一桩并不愉快的婚姻然并奔向伦敦后,他方才找出真正的自我——里克·杰柯斯基,一位胖滚滚的书商,对所有大块物件都有个好胃口,并痴狂于葛洛丘·马克思的名言:&书于犬外,人之挚友;书于犬内,暗不能阅。&
