在结构上

The structure and tectonic of Earth's interior media are intrinsically inhomogeneous and anisotropy.

地球内部各圈层的结构和构造在本质上是不均匀的和各向异性的。

The surface formation energy calculation shows that for Cr/W(100) and Cr/W(110) system, one monolayer Cr is stable against the formation of interdiffusion structure.

表面形成能计算表明对于Cr/W(100)和Cr/W(110)体系，完整的Cr单层薄膜相对于扩散结构（即表面层和界面层的两个不等价原子中的一个发生互换）在能量上是有利的。

The results show that the experimental results are in good agreement with the values of viscosity in a part of temperature range that has been reported, with the relative error of less than 2.5%; In the process of ascent and descent temperature, the irreversible phenomenon of the curve of viscosity versus temperature V presents interzone characteristic, and the break of viscosity at critical temperature reflects jump change of melt structural information; It is one to one correspondence between viscosity and atomic size, and this relation is consistent with the Hall-Petch formula in expression way.

结果表明：实验结果与已报道的部分温度区间内的黏度值基本一致，相对误差低于2.5％；升温和降温过程中，黏度－温度关系曲线V的不可逆现象具有区间特征，临界温度时黏度的突变反映出熔体结构信息的跳跃变化；黏度与原子集团尺寸之间存在一一对应关系，该关系在表达上符合Hall-Petch公式。

Execute the whole nation to unite tax rate, break area space, the operator of intromit carriage market is lost in duty go up to be close to more at same scratch line, the compasses with professional subsistent transportation enterprises expends favourable policy also not answer existence, the competitive regulation of market economy is reflected adequately, be helpful for uniting the formation of the carriage market with open, orderly competition.

实行全国统一税率，打破地区分隔，使进入运输市场的经营者在税负上更接近于同一起跑线，专业运输企业实际存在的规费优惠政策也不复存在，市场经济的竞争规则能更充分地体现，有利于统一开放、竞争有序的运输市场的形成。1 。1 。2 有利于优化运力结构实施费改税后，燃油税的支出大于规费的支出水平。

We studied experimentally the effects of diet breadth and nutrient availability for the host algae on fitness components of the herbivorous isopod Idotea baltica.

我们研究了寄生在水藻上的食草性等足类的摄食范围和营养结构。

This is because they have a quiet similar microstructure,so isoprene rubber has the same excellent combination properties with natural rubber in performance.

这是因为它们有着十分相似的微观结构，因此异戊橡胶在性能上与天然橡胶有着一样的优异综合性能。

Although cold dark matter has its own problems in explaining cosmic structures [see "The Life Cycle of Galaxies" by Guinevere Kauffmann and Frank van den Bosch; Scientific American, June 2002], most cosmologists consider these problems minor compared with the difficulties faced by alternative hypotheses.

虽然冷暗物质在解释宇宙结构上也有它自身的问题（见《科学人》2002年8月号〈星系传奇〉），但大多数宇宙学家认为，较诸其他假说所面对的困难，这些问题可说是次要的。

The result shows: First, as coal changes to natural coke, its d(002) decreases, while its L and L increases; Second, there is a obvious borderline of structure parameters between coal and nature coke; Third, with the increase of metamorphosing degree, the diffraction apex of d(002) changes to higher angle, and the shape of apex changes from laigh to lofty.

结果表明：①随着煤向天然焦的转变，其d(002)减小、L、L等值增大；②煤与天然焦在结构参数上存在明显分界；③随着煤变质程度的增加，(002)衍射峰向高角度方向偏移，峰形由低矮变为高耸。

One reason for this is structural, reckons Leigh Sparks of Stirling University in Britain.

英国斯特灵大学的李·斯巴克认为问题之一是出在供应链结构上。

Newcharacteristics of supply include: the transmission of Net-commodity I through intemet--intemet supply, and the direct supply caused by the reduction in the links of commodity circulation. Because of its unique cost structure, the supply of Net-commodity I is that of zero marginal cost and its supply curve is level. What is corresponding with demand expression is mass customization, and thus leading to the integration of supply and demand.

在供给上的新特点包括：网络商品Ⅰ通过网络的传输——网络化供给；流通环节减少导致的直接化供给；由于独特的成本结构，网络商品Ⅰ的供给是零边际成本的供给，它的供给曲线是水平的；与需求的表达相对应的是定制化供给，由此也导致了供给和需求一体化的趋势。

This essay chooses the study aim from biology teachers in middle school in Shi Jiazhuang which tells us that most of the middle school biology teachers in Shi Jiazhuang have the"burnout", lower successfulness, individualize.

本文选取石家庄市初中生物教师作为研究对象，运用问卷调查的方法对石家庄市初中生物教师职业倦怠的现状进行调查，调查结果发现，石家庄市初中生物教师这一群体普遍存在职业倦怠，情感枯竭程度偏高，成就感偏低，去个性化程度最为严重。
