无选择的

From the perspective of Adaptation Theory language use can be defined as the continuous making of linguistic choices.

从顺应论的角度出发，使用语言是一个不断选择语言的过程，不管这种选择是有意识的还是无意识的，也不管是出于语言内部的原因还是出于语言外部的原因。

You may not have a choice about doing this, but Chapman counsels, Time is the one benefit you have.

你可能无选择权利要被迫执行这些命令，但是Chapman认为：时间也是你的福利之一。

The selection of geological prospecting in different stages(initial-prospecting, detailed-prospecting)(2)the selection of geological prospecting in the deep-laid and shallow-laid of tunnel project (3)the selection of geological prospecting of tunnel projecting in different geological conditions Finally, the author summed up main problems needing to be solved in tunnel engineering geological prospecting as follow:(1)differentiate stratum and find out the depth and thickness of different stratums in the tunnel section (2)find out geological structure and existence situation of fault, broken zone and weak plane (3)find out weathering level of bed rock to classify surrounding rock combining speed materials (4)differentiate stratum structure of the entrance of tunnel to judge the stability of it (5)find out existence situation and performance of ground water (6)situations of other harmful geological phenomenon In view of above problems and classification of surrounding rock, the author showed principles of rational choosing of methods in geological prospecting and counted disperse range of physical character parameter value in different petrosal character, getting achievements as follow:(1)summarization of effect, merits and demerits of different geological prospecting methods in the tunnel geological investigation (2)method selection and arrangement principle of tunnel engineering geological prospecting in different geological conditions and prospecting stages (3)According to previous experience and cases, the author concluded the物性parameters most in use ,and showed the basis of selecting geological prospecting methods in different geological conditions.

论文中用几个应用实例来说明：(1)不同勘察阶段物探工作的选用；(2)深埋、浅埋隧道工程物探工作的选用；(3)不同地质条件隧道工程物探工作的选用。最后总结归纳出隧道工程物探所需要解决的问题主要有：(1)划分地层，查明隧道通过剖面的各地层深度与厚度。(2)查明地质构造，隧道轴线段有无断层、破碎带、软弱层面等。(3)查明基岩风化程度，从而结合速度资料进行围岩分级。(4)划分洞口地层结构，判断洞口稳定性。(5)查明地下水赋存情况及其活动动态。(6)其他不良地质现象存在情况。针对上述需要查明的地质问题与计算围岩分级情况，论文提出合理选用物探方法的原则，并统计了物性参数值在不同岩性中的分布范围。得出以下研究成果：(1)总结出各物探方法在隧道地质调查中的作用和优缺点。(2)得出不同地质条件下和不同勘察阶段，隧道工程物探方法选择和布置的原则。(3)根据以往工作经验和事例，对常用的物性参数进行了归纳总结，同时介绍了不同地质条件下物探方法选择的依据。

Because there is a large variety of the international factoring, such as double factor system and single factor system, non-recourse factoring and recourse factoring and so on.And different varieties can mutually combine, so the customer operates the different ways when choosing different factoring,naturally the factor may face different risks.This involves wide and complex contents.Owing to the article space, this text only analyzed the risk that the factor face taking the double and nonrecourse factoring for example, needing to have more research still.

由于国际保理种类很多，比如无追索权保理，有追索权保理，单保理、双保理等等，而且不同的保理方式又可以相互组合，因此客户在选择不同的种类的时候其运作方式是不一样的，那么保理商所面临的风险也是有所差别的，这涉及面很广而且内容也十分庞杂，鉴于文章篇幅，本文只对无追索权的双保理模式中保理商所面临的风险进行了粗浅的分析，尚待更加细致的研究。

The great tour purchasing power is the drive power of promoting the region's tourism developmentln the regional space, scale economic and regional separation are one of the basic characteristics of promoting tourism industry, So we must arrange the regional tourism industry with a systematic method and give prominence to the central city. For its outstanding area in the regional space, central city has evident superiority in the regional ecnomic development, and has echelon between central city and its periphery scennic spots, which is the inducement mechanism of tourism industry's arranging, developing and advancing step by step. For the law of diminishing marginal utility and the theory of equilibrium, the max utility equilibrium of tourism consumption be at the point of tangency of undiscrepancy curve and the cost budget curve.

中心城市居民巨大的出游力是拉动其周边旅游地发展重要的内在驱动力；由于地缘关系，区域规模经济与地域分割并存，是旅游产业运动的一个基本特征，为此必须对区域旅游经济进行系统化布局，突出中心城市的产业中心性；因其区位条件独特，中心城市在区域经济发展中居于明显的优势，与周边城乡部位存在经济发展上的梯次性，这种梯次性是区域旅游生产力布局、产业发展梯次传动，最终整体联动的经济诱导机制；根据边际效用递减规律和旅游者最大效用均衡理论，旅游消费效用最大化的均衡在无差异曲线与开支预算线的切点(即旅游目的地选择的最佳位置)上，且随着边际效用递减，目的地选择的最佳位置向远离中心城市方向移动，这就是中心城市与周边旅游地互动关系的经济学解释。

The difference between codon choice randomization in the region of protein regular secondary structure and that in coil region is investigated in detail. We find that the folding free energy of mRNA segments in different protein secondary structures is significantly different. The average Z score is -1. 38 and -1. 71 for regular secondary structure, but -0.93 and -1. 03 for coil.

我们仔细分析了在蛋白质规则结构区域（alpha螺旋和beta折叠）和无规则结构区域密码子随机选择的差异，发现处于不同蛋白质二级结构的mRNA片段的折叠自由能有显著的不同，对于规则结构，Human和E.coli的平均Z-score值分别为-1.71和-1.38，但是无规则结构的Z-score值分别为-1.03和-0.93。

Objective:To study the relationship between syndrome differentiation of TCM and the plasma level of CD_(62P) in chronic atrophic gastritis,to understand the relationship. between the different type of syndrome of TCM and stagnant blood,to provide the theory which to add the herbs of eliminating the stagnant and activizing the blood to. cure the chronic atrophic gastritis.

目的：本研究通过对已确诊为慢性萎缩性胃炎(chronic atrophic gastritis，CAG)的患者进行中医辨证分型及血小板膜上P选择素CD_(62P的测定，从而探讨该病的中医证型与血小板膜上P选择素CD_(62P之间有无一定的相关性，了解不同证型CAG与瘀血之间的关系，为在治疗CAG的中药中酌情加入活血化瘀的药物，提供理论依据。

This article analyzes the working theory and the working forces of the drive wheel, pyramid wheel and outer ring during the transmission process. It also deduces the practical calculation formula of the pyramid wheel type variable speed drives, it also goes on the material calculation aim at the selection parameter. It protracts the assemble-drawing of the pyramid wheel type variable speed drives and the accessory-drawing of the mostly drive component. So it can express more clearly of the structure and process planning of the variable speed drives.
