The influence of drying parameters of freeze-drying on quality of pteridium aquilinum drying was investigated, and the impact of drying board temperature, drying chamber pressure and material thickness on Vc content was studied by nonlinear regressional orthogonal design.

考察干燥因子对真空冷冻干燥蕨菜品质的影响，用二次正交旋转组合设计的试验方法，分析搁板加热温度、干燥室压力和物料层厚度对蕨菜Vc含量的影响规律，建立了冻干因子与Vc含量的回归模型。

Then the flow in the curved pipe and reducing pipe was simulated through using CFD software, know that fluid passing curved pipe, reducing pipe can form secondary flow, vortex shedding, circumfluence, occur separation of boundary layer and periodic circulation flow, make the fluid pulsant, then cause the pipe vibrancy.

然后再应用通用CFD软件对具有弯曲和变径的热风炉管内流场进行模拟，得到当流体流过弯管、文氏管后形成了二次流、环流，并发生边界层分离和周期性旋涡脱落，它们会使后面的管流处于脉动状态，脉动状态的流体在管内流动时，会引起管道系统产生振动。

The theoretic results show that retroreflective intensity increases gradually with accretion of refractive index when refractive index is less than two, but decreases when refractive index is great than two.

研究结果表明，折射率增大，折射率小于2时，回向反射性能逐渐增强，相反，在折射率大于2时，回向反射性能减弱；反射层面积的大小会影响入射光线的完整回向反射过程；最后定义了有效回向反射角度，并给出了玻璃微珠在激光照射下的二维回向反射光照度分布。

Ten optic disc stereometric parameters including"tw o-dimensional","three-dimensional"and "RNFL-related"parameters were acqu ired to assess the intraobserver and interobserver reproduci...

结果：观察者内和观察者间各视盘参数的ICC值均较高，分别为，正常人组0.811～0.998和0.724～0.963，青光眼组0.803～0.996和0.637～0.897，其中观察者间各视盘参数测量的ICC值在正常人组和青光眼组差异有显著性(P=0.000)，ICC值在&二维&视盘参数、&三维&视盘参数及&与视网膜神经纤维层相关的&视盘参数呈递减分布。

Unfortunately, up to now, there is not a sort of two-dimensional arrays with fine property of tomographic imaging and high photon collection rate.

目前仍没有一种理想的二维阵列既具有较高的量子收集率，又具有良好的层析成像特性。

Sighing, he dipped his brush and passed it along the topmost plank; repeated the operation; did it again; compared the insignificant whitewashed streak with the far-reaching continent of unwhitewashed fence, and sat down on a tree-box discouraged.

他叹了一口气，用刷子蘸上灰浆，沿着最顶上一层木板刷起来。接着又刷了一下，二下。看看刚刷过的不起眼的那块，再和那远不着边际的栅栏相比，汤姆灰心丧气地在一块木箱子上坐下来。

In the design, we should note two things: It is a wine of surface material and the adhesive strength between the inner layer material is lower than the label adhesive strength; second label wine of the tear strength is higher than the surface material The tear strength, its purpose is to easy to damage when in open box Diaobao Cartoning.

在设计时，我们应注意两点：是一酒盒表层材料与内层材料之间的粘合强度要低于标签的粘合强度；二是标签的抗撕裂强度要高于酒盒表层材料的抗撕裂强度，其目的是为了易于在开盒时破坏掉包装盒。

Its emission accounts for half of the hydrocarbons total one, and especially is very high in the rural and well vegetated areas, which greatly influences the regional environment such as ozone concentration.

异戊二烯(C_5H_8)是对流层中重要的NMHC，也是植被释放最多的挥发性有机化合物，其排放量占植物烃类总排放量的一半，特别是在农村和边远地区大气边界层中含量很高，往往对局地大气环境，如臭氧浓度有很大的影响。

During well drilling, LWD monitoring device, comprehensive logging device, cutting logging, seismic interpretation, geologic models, and many other technical measurements had been used for real-time monitoring and comprehensive analysis. What had been done helped geosteering, and the putting forward of drilling track. The horizontal wells drilled in ultra thin single sand layer with the thickness of less than 2m, and the penetration rate for sandstone was higher.

在现场钻井过程中，采用LWD监控仪、综合录井仪、岩屑录井、地震解释、地质模型等多种技术手段相结合，实时监控，进行综合分析，为地质导向提供依据，并准确地指导了钻井轨迹运行，实现了在不到2m的超薄单砂层中穿行，达到了较高的砂岩钻遇率，并成功的穿越了小断层，实现了二次着陆。

Objective To isolate,identify and purify the allergens in egg.Methods The albumen was extracted from the egg and the albumen from the vitellus.The total protein of the egg was isolated by SDS-PAGE.The allergens of egg were identified by Westernblotting.

分别提取鸡蛋的蛋清与蛋黄的蛋白，通过十二烷基硫酸钠-聚丙烯酰胺凝胶电泳分离鸡蛋的蛋白质组份，采用免疫印迹(Western-blotting，WB)方法鉴定过敏原，通过离子交换层析对鸡蛋主要过敏原进行初步纯化。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
