CPL language based on ALGOL 60 close to the hardware, but relatively large scale, it is difficult to achieve. University of Cambridge in 1967 of the Matin Richards made to simplify the language of CPL, the introduction of the BCPL (Basic Combined Programming Language) language. In 1970 the United States Ken Thompson of Bell Labs to the basis of language BCPL, but also further simplified the design of a very simple hardware and is very close to the B language and language with B first UNIX operating system, the PDP-7 to achieve.

CPL语言在ALGOL 60的基础上接近了硬件一些，但规模比较大，难以实现。1967年英国剑桥大学的Matin Richards对 CPL语言作了简化，推出了BCPL（Basic Combined Programming Language）语言。1970年美国贝尔实验室的 Ken Thompson以 BCPL语言为基础，又作了进一步简化，设计出了很简单的而且很接近硬件的 B语言（取 BCPL的第一个字母），并用 B语言写第一个UNIX操作系统，在PDP-7上实现。

Owing to the drawbacks of analytical shimming, this paper puts forward the concept of passive numerical shimming for searching a method of compensating Bz'easily to a high level and with a low cost. Based on the magnetic field caused by a magnetic moment, the distribution of moments in a superconducting NMR imaging megnet can be determined through some pseudoinversion algorithm directly from Bz'. The moments are used to compensate Bz'.

无源数值匀场的出发点直接是不均匀磁场的磁场偏差B〓本身；无源数值匀场的基础为磁性材料的磁矩所产生的磁场；由已知B〓，通过某种逆运算，确定磁性材料的磁矩在主磁体中的分布，实施此分布，以磁性材料的磁矩所产生的磁场直接对B〓进行补偿——这便是本文提出的无源数值匀场的概念。

Did I ever tell you, old boy,' he said, chuckling round the stem of his pipe,'about the time when those two nippers of mine set fire to the old market-woman's skirt because they saw her wrapping up sausage s in a poster of B.B.?

"我还没说哩，伙计，"他叼着烟斗，一面说道：有次我那俩小家伙，在市场把个老太太裙子给点着啦！那老家伙？她拿B.B。的像片包香肠！

Earlier this week, the P.B.G.C. took over the pensions of almost two thousand workers and retirees for Oneida Limited, a maker of cooking tools. The P.B.G.C. says it pays monthly benefits to almost seven hundred thousand retirees in about three thousand six hundred pension plans.

这周初，P.B.G.C接管了奥纳达有限公司的差不多两百个工人的和离退休人员的养老金。P.B.G.C说他们每月要支付差不多700000离退休人员的大约3600种退休计划。

For the first time, this study conducted a series of field sampling in multiple locations over several years and demonstrated that the B and Q biotypes first invade areas with high frequency of transport through human movement of plant materials, and then rapidly spread into surrounding areas and displace indigenous genotypes, and in parallel with displacement significant changes in sex ratio occurred in the mixed populations. Crossing experiments demonstrated that in the B. tabaci species complex there are many genetic groups that are completely or nearly completely isolated in reproduction. Apart from behavioural mechanisms, difference in host plant suitability and insecticide susceptibility between whitefly biotypes may also play important roles in the displacement of indigenous whiteflies by alien whiteflies in Zhejiang.

本研究首次以一个地理区域内广泛系统的野外调查数据证实，B型和Q型烟粉虱首先通过花卉苗木调运入侵交通较为发达的地区，然后迅速向周边扩张并取代土著烟粉虱，同时入侵取代过程伴随着混合种群中性比的变化；杂交试验证明烟粉虱复合种内存在多个生殖上隔离或基本隔离的遗传群；B型烟粉虱在浙江省内迅速取代土著烟粉虱，除行为机制外，生物型之间寄主适应性和药剂敏感性等方面的差异也可能在此过程中起着重要作用。

As we all know, the B shares is a lot of domestic institutions and individuals, so they voted for the majority of people is not surprising, however, after all, there are 17.433 million shares of B shares voted, indicating there is still opposition to ShenNan Xinhua shareholders perfidious The default behavior.

大家都知道，B股是对境内机构和个人很多，因此他们对多数人投票是不足为奇的，然而，毕竟，有17433000股B股投反对票，这表明仍然有反对深南电股东背信弃义的默认行为。

It is a difficult problem for a big prime integer, if we select a primitive root according to its definition the performance of the secret communication could be affected seriously since the operation cost is very high. So this paper presents and proves an algorithm for searching a primitive root with high efficiency and gives the design of flow and corresponded JAVA program.

第一步：随机选取大素数P和在GF上的本原根g，并将P和g作为公开信息；第二步：用户A想和用户B建立保密通信时，就要交换共享的密钥KAB，A随机选取整数XA(1≤XA≤P-1)，并且计算出YA=gXAmodP经共用信道传给B，将XA保密；第三步：用户B随机选取一整数XB(1≤XB≤P-1)，计算出YB=gXBmodp，也经共用

With the reduction of SOM content and the elevation of contamination concentration, the difference between PHE and PYE decreases gradually, while B［a］PYE exhibits a significant difference from them. This could be attributed to the high lipophilicity and large molecular size of B［a］PYE, which make the molecule of B［a］PYE to be more easier to be held in the nanopores of clay and the dense region of SOM.

不同多环芳烃SPMD辅助解吸率差别很大，随着土壤有机质含量的降低，以及污染物浓度的提高，菲和芘的解吸差异逐渐缩小，而苯并［a］芘与上述2种多环芳烃的差异很大，主要是由于苯并［a］芘具有高度亲脂性，并且分子较大，造成其容易滞留在粘土的微孔及有机质的致密结构中。

A series of alkyl rhodamine B esters were designed and synthesized from rhodamine B.

以罗丹明B为原料设计合成了一系列的烷基罗丹明B酯衍生物。
