Both of the ESD were proportional to kVp 2.2 to kVp 2.5 and were linear proportion to mAs. Inverse square law exists in the relationship of focus-film distance, FFD, and ESD. The impacts of field size and patient thickness to ESD are negligible. Optimized operating condition is chosen to improve the diagnosis rate and to reduce the patient dose. The ESD, 0.12±0.06 mGy, performing the optimized operating condition of chest x-ray examinations, is less than both values of reference doses recommended by NRPB and IAEA.

研究结果发现，入射表面剂量随操作条件而变，以相同的条件照射，三相位X光机所造成表面剂量大约是单相位X光机的1.9倍；入射表面剂量与kVp的2.2至2.5次方成比例，与mAs约成线性正比，与焦斑至底片距离的关系大约符合平方反比定律；照野面积及身体厚度虽会影响表面剂量的大小，但其程度远低於kVp及mAs的影响。

The number of high net worth women, those with three million dollars or more in investable assets, is growing at nearly double the pace of men in this group, that's according to a recent survey by Merrill Lynch.

越来越多的女性走上了工作岗位，她们创业的增长速度是男性的两倍，有大约三分之一的职业女性收入超过了她们的配偶，一直以来把男性作为主要服务对象的金融服务领域正在关注着这一现象。

For the purpose of avoiding vexatious litigation, the parties are sometimes deterred by pecuniary penalties, and sometimes by an oath which is imposed by the Pr?tor. In certain cases an action for double damages is brought against a defendant; for instance, in the collection of a judgment debt, or for money expended for a principal, or for unlawful damage to property, or where proceedings are instituted to collect legacies left by condemnation. In some instances, the deposit of a forfeit is permitted to be made, for example, in an action

对于持否认态度地人，在某些情况下规定了双倍诉讼，比如，当因已决案、已清偿物、非法损害或者间接遗赠等问题而被诉时，在某些情况下，允许作出承诺，比如：当因借贷确定数额的钱款或者关于钱款的债务协议而被诉时；然而，在借贷确定数额的钱款的情况下，罚金未三分之一，在关于钱款的债务协议的情况，为二分之一。

Sometimes the context of the mode would require a group of only two semibreves, however, these two semibreves would always be one of normal length and one of double length, thereby taking the same space of time, and thus preserving the perfect of the tempus. This ternary division held for all note values.

有时候根据实际情况的需要一组仅有2个全音符，但是这种2个全音符的模式也总是标准长度中的一种并且是这个长度的两倍，因此有着相同的时长，其结果是即使保留节拍的一部分，这种三分法包含了所有的音符价值。

They are often morphologically distinct from A chromosomes, being smallerand more highly heterochromatic in most cases. B chromosomes do not pair with Achromosomes, and they are inherited in a non-Mendelian way, exhibiting meiotic andmitotic instability and nondisjunction. However, B chromosome DNA is quiteidentical to the corresponding sequence on the A chromosome complement. So far afew B chromosome specific DNA sequence have been identified. Specific DNAsequences on B chromosome have been the attractive research area on Bchromosomes.

现已在千余种植物和近三百种动物中被发现。B染色体与物种中正常染色体不同：独立于整倍体基因组之外，减数分裂时不与A染色体发生联会和配对，细胞分裂后期不分离，非孟德尔遗传，富含异染色质，不含对宿主主要性状有影响的基因等。B染色体DNA的分子组成既与A染色体极为相似，具有A染色体DNA分子组成的一般特征：富含重复序列和转座成分，染色体三大功能组件DNA高度同源；又与之相区别，含有B染色体特异的DNA序列，这些DNA序列可以为探讨B染色体的起源和进化提供有价值的信息。

Under the assumption of a sech〓 input pulse, TOD is significant only for pulse widths less than 10 femtoseconds resulting in pulse broadening as well as distinct amplitude oscillations on the leading edge. TOD is positively correlated with its length. The calculations presented here allow for the determination of the maximum thickness of crystal that may be used in the autocorrelation system.

结果表明当脉宽接近或小于10fs时，脉冲才有明显的展宽效应，脉冲的展宽倍数与晶体的长度成递增关系，计算同时给出能基本消除三阶色散的展宽效应的倍频晶体的最大厚度，为进一步实验研究提供了依据。

Taiwanese tourists visiting Alaska in 2008 is over one time the numbers of the tourists in 2007 because China Airlines launches the reasonable-priced travel package. Kuo General represented that the best seasons to visit Alaska are summer and winter. More than 3,000 Taiwanese tourists go to see the glacier, wild animals, and salmon backflow in Alaska every year. Also, the northern lights could be seen from October to March.

华航经济实惠的旅程，受到许多想游阿拉斯加台湾游客的喜爱，自2007到2008年台湾到阿拉斯加的背包客更是成长一倍之多，郭倩仪经理表示，夏季与冬季是游赏阿拉斯加最佳季节，台湾游客每年有三千多人搭乘邮轮游赏阿拉斯加的冰河、野生动物、鲑鱼回流，还可目睹大灰熊抓鲑鱼的生态景观；冬天十到三月是欣赏北极光最佳的时间。

In this paper,the behavioral,physiological, ecological adaption mechanism of H.armigera and H.assulta to their common host plant tobacco were studied comparatively,and the main results were summarized as follows:Electroantennogram response of adult to tobacco volatiles:(1) H.armigera and H.assulta elicited similar EAG responses to the tested 20 tobacco volatiles;both of them elicited significantly more sensitive to green leaf volatiles,aliphatic and aromatic compounds, than to monoterpene,sesquiterpene,heterocyclic compounds under lower concentration; while the similar EAG responses under higher concentration were detected,but most of them were not significantly different with each other.

本文从行为、生理和生态适应三个方面，对棉铃虫和烟夜蛾与烟草间的互作进行了比较研究，主要结果如下：成虫对烟草挥发物的EAG反应：(1)两种夜蛾对测试的20种烟草挥发物均可产生EAG反应；低浓度下对绿叶气味、脂肪族、芳香族化合物的EAG反应显著高于单萜类、倍半萜类和杂环化合物；高浓度下的EAG反应也表现出相似的总体反应趋势，但多数反应值间的差异未达显著水平。

Results showed that all the three sweet sorghum varieties contained plentiful sugar, which can provide enough carbon source for alcohol fermentation, however, total nitrogen and some mineral elements（Fe3＋）cannot meet the needs of alcohol fermentation. Activity of most microbes in stalk juice can be inhibited and the sugar can be maintained when the stalk juice was condensed to 4～5 times. Due to the reasons that the activity of acetous microbe or hydrolysis enzyme inside stalk juice can be maintained, ratio of reducing sugar to total sugar was increased with storage time at 55～60℃,0.15 MPa vacuum condensed condition, which can be beneficial for the purpose of alcohol fermentation.

结果表明，三个品种都含有丰富的糖分，可以为酵母菌发酵制取酒精提供良好的碳源，但总氮和某些矿物质元素（如：Fe3＋）不能满足酒精酵母的营养需要；甜高粱茎秆汁浓缩至4～5倍时，可以抑制汁液中大多数微生物的活动，使其中糖分不受损失；在试验设定的真空浓缩工艺条件下（55～60℃，0.15 MPa）甜高粱茎秆汁中产酸微生物或水解酶类仍保持活性，使得还原糖占总糖的比率随贮藏时间延长而升高，这有利于酒精发酵。

I will endeavour to find you some assistance.

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
