Bohlen suggested that an alternative is to place strong pressure on the European nations to plan by underscoring their situation and making clear that the only politically feasible basis on which the US would be willing to make the aid available is substantial evidence of a developing overall plan for economic cooperation by the Europeans themselves, perhaps an economic federation to be worked out over 3 or 4 years.

为了在这两种危险中取得平衡，波伦先生提出了另一种路线，那就是向欧洲国家施加强大的压力迫使其进行计划，方法是强调他们的处境，使他们明白，美国愿意向欧洲提供援助的政治上可行的唯一基础就是：有足够证据表明，欧洲人自己正在做出进行经济合作的全面计划。或许将在三到四年内建成一个经济共同体。

Both the Clemenceau and her American berth-mates are old, and thus contain nasty chemicals, including mercury, lead, asbestos (a fireproof mineral widely used before its toxic properties became known) and polychlorinated biphenyl (poisonous chemicals used in electronics until their banning in the 1970s).

克莱蒙梭号与并排系泊的四膄美国军舰一样，舰体陈旧，含有大量有毒化学物。主要有水银、铅、石棉、多氯联苯等。石棉是一种有毒的矿物，在人们认识到它的毒性之前被广泛用于防火材料。而多氯联苯是一种有毒的化合物，之前广泛用于电子产品中，二十世纪70年代被禁止使用。

The phytoplankton community was mainly composed of Cyanophyceae, Euglenophyceae, Bacillariophyceae, and Chlorophyceae, and the dominant species were Oscillatoria subtillissima, Dactylococcopsis irregularis, Euglena caudata, Melosira granulata, Cyclotella meneghiniana, Chlorella vulgaris, and Scenedesmus quadricauda. The main environmental factors affecting the distribution of phytoplankton species in July were ammonium-nitrogen, dissolved oxygen, water temperature, and total phosphorus, while those in September were pH, water temperature, dissolved oxygen, transparency, and total nitrogen. Water transparency and zooplankton were the main factors affecting the biomass of Cryptophyceae, Pyrrophyceae, and Bacillariophyceae; while nitrogen, phosphorous, and dissolved oxygen were the main factors affecting the biomass of Cyanophyceae, Euglenophyceae, and Chlorophyceae.

结果表明：调查期间共鉴定出浮游植物384种，隶属于8门，浮游植物密度范围为2.01×105～57.60×105 cells·L-1；群落组成以蓝藻、裸藻、硅藻和绿藻为主，主要优势种有细微颤藻、无常蓝纤维藻、尾裸藻、颗粒直链藻、梅尼小环藻、普通小球藻、四尾栅藻等；7月影响浮游植物分布的主要环境因子依次为铵态氮、溶解氧、水温和总磷，而9月的pH值、水温、溶解氧、透明度和总氮含量对浮游植物的分布产生影响较大；其中，透明度和浮游动物量是影响隐藻、甲藻和硅藻藻类生物量的主要环境因子，而蓝藻、裸藻、绿藻主要受水体氮磷营养盐浓度和溶解氧的影响。

In Chapter 4, A detailed comparison between the realization of Cholesky decomposition and OR method is given, a systolic/wavefront array made of general purpose DSP is used to realize the adaptive beamforming at a moderate speed, and a wavefront array to extract the adaptive weights which is necessary in some applications is designed. In Chapter 5, the author proposed a new structure to realize the space time adaptive processing. First 1~q using the FFr and the truncating infinite sequence and sone optimizing method, a much simpler architecture can be acquired in realizing the three portion of channel processing: quadrature sampling, pulse compression and adaptive equalization.

第五章研究并提出了用全通用DSP模块设计空时二维自适应信号处理机的新方案，首先用快速付立叶变换和对长序列截断处理的重叠保留法以大大减少的运算量完成了处理机通道处理部分的正交插值、脉压、自适应均衡三个功能块的长阶数线性卷积运算，接着对自适应波束形成提出了多种实现方案，分析了多种方案下的运算量和设备要求，指出在不同通道数、不同数据吞吐率、不同自适应要求时这几种方案有不同的可行度和实现难度，并针对实际要求确定了一种运算田N、的实现方案，对自适应波束合成部分的大量贝玉以良元组咸肋冈络结拘和处凰闺和羽凶挝娠昨了优化设计以威少设备复杂性，构成了设备量大夕父伯小、们g团回高、辜于生回阴田闩引愧快的空时二维自适囱戏升引毗四机。

The effects of bill hypothecation include: the proving effects of right, it is the analyses about the way that the holder proves that he is the owner of the right according to the endorsement; the effect of stopping the countervailing power, it is the analyses about the way of stopping the apply of the obligator's right of defense against the pledger; the effect of transfer endorsement, i

文章的第四部分，对票据质押权人实现质权的方式做出解释和分析，1、向付款人请求付款，是主债务未到期而票据已到期时，票据质押人作为主债权人，即可以依背书的连续性证明自己权利的存在，持票据提示付款人付款的问题。2、行使票据追索权，是付款请求权的一种补充或保障性的权利，作为第二次请求权有效地起到了保障票据债权流通、票据制度规范运行的作用。3、票据届期与其所担保的债权的届期问题，由于票据的到期日与其所担保的债权的期限有所不同，所以在票据债权的实现上有异，现实中票据的到期日与其所担保的债权的期限的不同，本文就票据所担保的债权与票据的到期日同时届期、票据的到期日先于被担保债权的期限到达、票据到期日后于被担保债权的清偿期到达，这样三种情况进行分析。

Irenaeus of Lyons in the late 2nd century, claimed in his Against Heresies, We however as always, the more now as better equipped through the Paraclete, that leader into all truth, believe as these do in the only one God, yet subject to this dispensation, that the one only God has also a Son, His Word who proceeded from Himself, by Whom all things were made and without Whom nothing has been made, that this Son was sent by the Father into the virgin and was born of her, both man and God, Son of Man and Son of God and was named Jesus Christ; that He suffered, died, and was buried according to the Scriptures and having been raised up by the Father and taken back into heaven, and sits at the right hand of the Father, He will come to judge the quick and the dead; and that thereafter He, according to His promise, sent from the Father, the Holy Spirit, the Paraclete, the sanctifier of the faith of those who believe in the Father, the Son, and the Holy Spirit.

透过信仰的成形与系统化表述，产生出我们现今所知道的正统教义：相信一位神以三个位格存在──圣父、圣子和圣灵──祂们彼此同等、同永恒并且同质（希腊文为 ousia ）。耶稣不能被视为从属於圣父，像诺斯底派教导说神具有层次；耶稣也不单是另一种形态，像撒伯流派所教导的，表示神仅仅是在不同时间以不同型式存在；耶稣更不是一个神的灵降在他身上，因此他才被选上的人，像亚流所主张的那样，生是一种创造性行为，所以基督事实上是有起源的。头四次教会古代会议决议应当要来肯定只有一位神，但是存在於三个位格：圣父、圣子和圣灵。

Also present in sugar beet extract are a trisaccharide, raffinose, which has a D-galactopyranosyl unit attached to sucrose , and a tetrasacchtride, stachyose, which contains another D-galactosyl unit.

制糖甜菜的提取液中还存在一种三糖，即棉子糖，它有一个D-吡喃半乳糖单元与蔗糖相连接；另外还存在一种四糖，即水苏糖，它含有另一个D一半乳糖单元。

Taken together, the findings provide support for the hypothesis that anatomical differences affecting gait existed among our earliest apelike ancestors, and that these differences provided the genetic variation which natural selection could act on when changes in the environment gave bipeds an advantage over quadrupeds.

第六段告诉了我们研究的两个假设：一种假设：猿人祖先在解剖学意义上存在着差异，这一差异影响了它们的步态；另一种假设：这些差异为自然选择所决定的遗传变异提供了可能性，而环境变化使得两足行走的猿人比起四足行走的猿人更有优势。因此B是答案。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
