着重介绍了该发电机转子旋转整流电路的接线方式和定、转子绕组结构，分析了发电机在空载和负载2种情况下的运行特性以及该系列发电机的设计特点，指出了采用该励磁方式的单相交流同步发电机在设计和制造过程应注意的问题。

Data stream model is different from traditional database. It has the characteristics of rapidness, real-time, continuousness and boundlessness. Therefore, the algorithms for mining data streams have substantial difference from that of traditional database mining. They are one-pass algorithms.

数据流模型不同于传统的数据库模型，具有快速、实时、连续、无界等特点，由此决定了数据流的查询或挖掘算法与基于传统的数据库的挖掘技术有显著的区别，其算法应是单遍扫描的。

According to the double-axis experiment and the uniaxial tension experiment, shear relaxation modulus and bulk relaxation modulus are obtained. Fractional exponent models[23][24][25] are applied to shear relaxation modulus and bulk relaxation modulus. The theory is proved by constant amplitude cyclic strain experiment. Better results are obtained from the comparison of theory curves and experiment results.

通过双轴拉压实验来确定材料的切变松弛模量，单轴拉伸实验来确定材料的体变松弛模量，对这两种模量均采用分数阶指数的形式来进行拟合，再用等应变幅循环历史的实验验证了理论，得到了较好的结果。

The documentary credit or letter of credit is an undertaking issued by a bank to the seller at the request and in accordance with the instructions of the buyer to effect payment (that is, by making a payment, or by accepting or negotiating bills of exchange) up to a stated sum of money, within a prescribed time limit against stipulated documents.

跟单信用证是银行应买方的要求并按照买方的指示开给卖方的付款（即支付、承兑或议付汇票）的承诺，保证在规定的期限内凭规定的单据支付一定金额。

The basic steps of this method are as follows.The firststep is to derive a necessary condition such that the families of quasipolynomials withone parameter,corresponding to the edges of the polytope,have pure imaginary rootsby using the Dixon's resultant for polynomials.Then to check that the casescorresponding to the parameters obtained in the first step are in fact impossible byusing the generalized Sturm criterion and some stability criteria.

其基本思路是先利用多项式方程组的Dixon结式理论导出使各棱边对应的单参数特征拟多项式有纯虚根时，参数值应满足的一个等式条件，即所谓的Dixon结式等于零，然后由广义Sturm判别法验证对所有参数值，Dixon结式不等于零，或使结式等于零的解不产生特征拟多项式的纯虚根。

Comparisons of conventional single-trolley and fully automated double-trolley quayside container cranes are conducted in operational characteristics and metal structure.

通过与常规单小车桥式起重机的对比，介绍了全自动双小车集装箱桥式起重机工作特性以及所引起的金属结构上的变化，提出了在金属结构的设计计算中应注意的方面。

Under the frame of Hamiltonian, the propagation of seismic wave is a symplectic group transformation with one parameter and consequently, the numerical calculation methods of the propagation ought to be symplectic method.

在哈密顿表述下，地震波标量方程描述的波场随时间的演化过程为波场在单参数辛群作用下的变换过程。因而在计算地震波场随时间的演化时，为保持系统的辛性质，应采用辛几何算法。

There is no mature scheme on haploidentical non-T-depleted transplantation in China. Prognosis of chemotherapy is poor for refractory and high-risk leukemia. Allogene hematopoietic stem cell transplantation should be applied without delay. If we can go beyond the histocompatibility leukocyte antigen boundary, HLA-haploidentical family members would became the resource of allo-HSCT donors.

目前，国内外尚无单倍型相合未去T细胞移植成熟的方案，对于难治和高危白血病患者，化疗预后是很差的，应不失时机进行异基因造血干细胞移植，如果能够跨越人类主要组织相容性抗原的限制，用人类主要组织相容性抗原半相合的亲属作为造血干细胞移植的供体，就可以彻底解决干细胞来源问题。

When single herbicide was used in the field for two years, the dominant species took place corresponding alternation. The community structure that originally mostly consisted of dicotyledonous weeds , such as Alopecurus aequalis sobol., etc.

通过连续几年的单一除草剂使用，烟田杂草的优势种群发生了相应变化，原来以看麦娘、马唐、稗草等单子叶杂草为主的群落结构演变成了现在以稗草、马唐及胜红蓟、两栖蓼、茴茴蒜为主的单、双子叶杂草混生结构，说明烟田施用除草剂会引起杂草群落结构变化，因此，在生产上则应注意除草剂的轮换使用。

The Buyer shall open, With a bank to be accepted by both the Buyer and the Seller, an irrevocable,intransferable and indivisible Letter of Credit at sight, allowing partial shipments and transshipment, in favor of the seller and negotiable against first presentation of the shipping documents to the Bank of China in China.

付款条件：买方应通过买卖双方同意的银行，开立以卖方为受益人的、不可撤销的、不可转让和不可分割的、允许分批装运和转船的即期信用证。该信用证凭装运单据在中国的中国银行见单议付。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
