But in summer time she was obliged to go barefooted because she was poor, and in winter she had to wear large wooden shoes, so that her little instep grew quite red.

不过她夏天得打着一双赤脚走路，因为她很贫穷。冬天她拖着一双沉重的木鞋，脚背都给磨红了，这是很不好受的。

In the double difference equation, the ambiguity can be divided into 2 parts, the first part is the integer one, the second part is the bias part caused by frequency difference.

在双差观测值方程式中，双差模糊度可分解为两项，第一项为整周项，第二项为站间单差非整周项，是由两卫星的频率差引起的。

The pacing of pacemaker can change the normal exciting sequence of heart and can lead to interatrial,interventricular,and atrioventricular asynchronism,thus result in adverse hemodynamic effect and consequent atrial mechanichal and electrical reconstitution.This is the main mechanism of developing atrial fibrillation.

心脏起搏改变了正常心脏激动顺序，使双房间、双室间及房室间激动不同步，带来不利的血流动力学效应，导致心房机械重构和电重构，这是房颤发生的主要机制。

In combination with the geological features of the ga wells in West Sichuan, such as multi-payzone high pressure gradients and a large lithological change in channel sand bodies, etc., the casing cementing and perforation completion were adopted for the main well and branch holes in the well group and the interzonal pressure seals of the main well and branch holes, and the separate well fracturing and producing were all realized through a completion string with dual-tubing and dual-packer.

结合川西地区气井多产层、高压力梯度、河道砂体岩性变化大等地质特点，该井组主井眼和分支井眼均采用套管固井、射孔完成，通过双油管和双封隔器的完井管柱实现了主井眼和分支井眼的层间压力分隔和分井压裂、分井采气。

The selection of materials,design and deposition of double waveband (3～5μm and 8～12μm) infrared antireflection on Ge substrate by ion beam assisted deposition are reported.

文中简要叙述了双波段(3～5μm和8～12μm)红外增透膜的膜料选择以及锗基底上红外双波段增透膜的设计与镀制，介绍了离子束辅助沉积技术制备该薄膜的过程。

Purpose To establish a RP Ion-pair HPLC method for the determination of dicyandiamide in metformin hydrochloride.

目的 建立反相离子对HPLC法测定盐酸二甲双胍中双氰胺含量的方法。

A plausible charge distribution of Fe and Mo valence states is proposed, and the stability of the compounds is discussed. Polycrystalline samples of 〓(0.8≤x≤1. 5) are prepared by solid-state reaction at high temperature. The alteration of the relative content between Fe and Mo in 〓 exhibits a significant effect on the crystal structure and the ionic ordering of the compounds.

采用传统高温固相烧结反应法合成了非化学配比的双钙钛矿型〓系列化合物。X射线粉末衍射数据分析结果表明，非化学配比的双钙钛矿结构〓（0.8≤x≤1.5）系列化合物的晶体结构随着Fe含量x的变化在x=1.2附近有一个由四方14/mmm对称向立方Fm〓m对称的结构结构相变发生。

With reference to the experience of specific practice on strategic alliance in typical domestic and overseas port like New Jersey Port in New York, port of Kaohsiung, Keelung and Taizhong, major ports in Yangtze River Delta, the possible modes of Rizhao Port strategic alliance were proposed. Based on the previous analysis, specific design on the supply chain management system of Rizhao Port viewing from strategic alliance was given in this dissertation, which mainly covered two aspects. On the one hand, based on the overall review of common design process, structure design and selection of partnership of supply chain management, and with consideration of the development trend of Rizhao Port, the double-sector style supply chain structure mode of Rizhao Port was put forward based on strategic alliance. On the other hand, in order to make it more clear on the specific process and contents of this kind of supply chain structure, the specific implementation of five supply chain for Rizhao Port in which capital was taken as the hub were proposed, named as, the coal supply chain based on norm regular ship transport mode, the ironstone supply chain based on cost optimization, the crude oil transport supply chain with the aim of extending petrifaction industrial chain, the timber transport supply chain based on circulating economy concept, and the farming transport supply chain based on futures theory.

在前文分析的基础上，论文重点论述了基于战略战略联盟的日照港口供应链管理的总体框架构建和具体规划设计两方面：一方面，在对供应链管理一般构建流程、结构设计、供需均衡及合作伙伴选择等方面进行全面总结基础上，并结合日照港口的发展趋势，推出了基于纵向战略联盟的日照港口集团式双扇形供应链结构模型；另一方面，为进一步理清日照港口双扇形供应链结构中相关供应链的具体流程及内容，特提出了以资本为纽带日照港口五大供应链的具体设计，即基于准班轮运输模式的日照港煤炭供应链，基于成本最优化日照港口铁矿石供应链，以延伸石化产业链为目标的日照港原油运输供应链，基于循环经济理念的日照港木材运输供应链，基于期货理论的农业定单式日照港农业运输供应链。

Hester had schooled herself long and well; she never responded to these attacks, save by a flush of crimson that rose irrepressibly over her pale cheek, and again subsided into the depths of her bosom.

但也有时候--好多天有这么一次，或者要好几个月才有这么一次，她会感到一双眼睛--一双人类的眼睛望着她那耻辱的印记，似乎能给她片刻的宽慰，象是分担了她的一半痛苦。

At the same time, real estate companies in return for cooperation has brought tangible business market, but also in the process of its own propaganda on all brands dedicated to promote, the formation of real estate companies, joint persons, owners, such as win-win situation.

与此同时，房地产公司，以换取合作带来了实实在在的商业市场，而且还的过程中，其自身品牌宣传的所有致力于促进，形成的房地产公司，合资者，所有者，如双赢双赢的局面。
