We transformed RMgBr into R-Ti derivatives with the production of byproduct MgBrO~(i-Pr at the same time, but we didn\'t need romove the Mg salt by centrifugation or chelating reagents, for bis[2-(N,N-dimethylamino)ethyl] ether could chelate with Mg atom and thereby reduced the Louis acidity of Mg salt, so we used R-Ti derivatives produced in situ to alkylate the aldehydes induced by BINOL-Ti complexes..

我们通过利用TiO~(i-Pr_4使格氏试剂转化成烷基钛，同时产生具有亲核加成促进作用的副产物MgBrO~(i-Pr，由于BDMAEE能与MgBrO~(i--Pr络合降低其路易酸活性，所以不需要离心或者借助络合试剂完全除去镁盐，而使用原位生成的烷基钛在BINOL-Ti诱导下对醛进行不对称加成。

When I is a two-dimensional matrix, then I is the intensity value at the position corresponding to row r and column c of the matrix.

设I是一个二维矩阵，则I就代表行r列c点的光强值。

Paul Erds once posed the following problem about real line R: is it true that, for every infinite set X, there is a closed set E with positive lebesgue measure such that E doesn't contain any subset similar to X (I.e., there is no subset of E, which is a linear homeomorphic image of X). In 1984, K. J. Falconer proved the following: for a decreasing sequence of positive numbers {xn} such that \%lim\%xn=0 and \%lim\%(xn+1)/=1, Erds problem has a partial positive answer.

叶盛 Paul Erds曾提出如下关于实直线R的问题：是否对R的每一个无限子集X，都存在一个具有正测度的闭子集E，使得E的任何子集都不相似于X(E的任何子集都不与X线性同胚)。1984年，Falconer证明了如下结论：对于一个满足limxn=0和lim(xn+1)/=1的单调递减的正实数列{x n}，Erds问题有一个部分肯定的解答。

The law of refraction, discovered first empirically by Willebrord SNELL, then subsequently derived formally by Descartes and Fermat, states that sin r = K sin i, where i is called the angle of incidence, the angle between the incident ray and the normal to the refracting surface.

折射的轨律，首先被 Willebrord SNELL 靠经验发现，接着后来正式被笛卡尔和 Fermat 认定，规定 sin r = K sin i ，这里 i 被称作入射角，入射光线和法线到折射平面之间的夹角。

Now Im complete, uh huh Still stallion, brick house, pile it on Ryde or Die, bitch, double R, cant crawl Beware, cuz I crush anything I land on Me here, aint no mistake nigga it was planned on And if I had to give you up Its only been a year Now I got my foot through the door And I aint goin nowhere It took awhile to get me in And Im gonna take my time Dont fight that good shit in your ear Now let me blow ya mind by lune

现在 Im 完成， uh 哼！使种马，砖块房子，堆起它安静在 Ryde 或一钢模，母狗，两倍的 R，伪善之言爬行小心， cuz 我粉碎我登陆的任何事在我在这里， aint 没有错误 nigga 它被计画在而且如果我必须放弃你它的唯一是一年现在我使我的脚通过门而且我无处的 aint goin 它一会儿拿让我获得录取而且 Im 去从容不迫 Dont 在你的耳朵中对抗好粪现在让我吹 ya 思想藉着弓形

Finally it is shown that if R is a ring with a nonzero local powerzero ideal then the matrix ring is a NCI ring.

最后证明了如果环R存在非零的局部幂零理想I那么R的全矩阵环Mn是NCI环。

In this paper, we generalize Gr〓bner bases theory to quotients of principal ideal domains and R/-algebras.

本文将Gr〓bner基推广到/J上及一类R/-代数上，R是主理想整环，p是素元，I≠0。

Result: Contrary to European and American people, I allele frequency of Han nationality is higher than that of D allele (P.05); II genotype frequency and DD genotype frequency are noticeably different from that of European and American people (P.01); No DD genotype appear in the excellent athletes, which is noticeably lower than that of control group and athlete group (P.05) and that of the excellent athletes reported in other countries; the frequency distribution of II genotype in Marathon is noticeably higher than that in 5km distance running(P.10); The changing of I allele Jl genotype IP ID genotype frequency indicates a stronger unary liner relation (r=0.9985) with the running distance lengthening(5ktru lOkrru Marathon).

结果显示：与欧美人群相反，汉族I等位基因频率高于D等位基因（P＜0.05）；汉族II型纯合子频率和DD型纯合子频率非常显著地区别于欧美人群（P＜0.01）；在优秀运动员中，DD型纯合子未出现一例，显著低于对照组和运动员（P＜0.05），也显著低于国外已报道的优秀运动员；马拉松项目II型频率分布显著高于5km（P＜0.10）；I等位基因、II基因型和ID基因型的频率变化伴随专项距离（5km、10km、马拉松）的增加呈现强相关的一元线性关系（r=0.9985）。

R: 'Roscoe', Dirty 30, you know, that's me -'the anchor of comedy on the team', you know, I lost my follow comedian Linsey Honder, he retired last year, so got to hold it down like that, but so far so good, you know, we've got some other comedians on this team too, which makes us all very close, I think we are closer than any other team out there, and that's just me, but I am serious on the court, but off the court, yeah, I am a jackass

R： 'Roscoe'，'Dirty 30'，你知道这就是我-队中的搞笑天王，我失去了我的伙伴-Linsey Honder，他去年退役了，所以我必须一个人撑下场面，目前为止做的还不错，你知道，我们队里面也有其他人会搞笑，这很拉近我们之间的距离，我想我们球队的队员关系是联盟中最亲密的。

And we also get the fact that many vat dyestuffs can not be suitable for spun-dyed for viscose as dyed-reagents with the way of "reducing-oxidizing", such as C.I. Vat Blue 6, C.I. Vat Red 29, C.I. Vat Black 29, C.I. Vat Orange 1, C.I. Vat Brown 3 and so on. But some vat dyestuffs have a stable color, such as C.I. Vat Green 3, C.I. Vat Black 8 and so on.

通过实验可知，还原蓝BC、还原大红R、还原灰BG、还原金黄RK、还原棕R等还原染料，在高浓度碱剂、带碱氧化等加工条件下会产生不可逆的色光变化，而且变化程度较大，使得这些染料均不能以&还原－氧化&方式应用于粘胶的纺液着色加工，而还原橄榄绿B、还原灰M等染料受高浓度碱剂、带碱氧化等因素的影响较小，色光较为稳定。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
