Coning and quartering method: put the sample onto the steel plate in the form of a cone; each scoop shall be inserted from the top of conical to make it spread along the top evenly, and pay attention not to misplace the center of cone; do it at least 3 times and mixed thoroughly; then flatten the top and use the cross plate from top to bottom to divide into 4 equal segments, randomly take out 2 oppositesegments and do it repeatedly for several times and finally divided into not less than the minimum retained quantity.

圆锥四分法：将样品置于已用样品刷好的钢板上，堆成圆锥形，每铲由圆锥顶尖落下，使其均匀地沿锥尖散落，注意勿使圆锥中心错位，如此反复至少移堆三次，使其充分混匀，然后将锥尖压平，用十字板自上插下，分成四等份，任取两个对角的等份，重复操作数次，缩分至不少于最少留样量。

heological properties at a low shear rate range(10-2-10s-1) and the glass transition temperatures for PEK-C with different moleCular weithts have been studied by using a cone/plate rheometer and DSC' The activation energy for melt flow increases with Mw The dependence of Tg on molecular weight exhibits two linear range and the value of nitersect agrees with the critical molecular weight , Mc' which is first reported for PEK-C' Mc value obtained according to η0 is about 8× 104 g/mol and the relation between Mc and temperature was dis-cussed.

用锥权流变仪及DSC的方法研究了5种不同分子量的酞侧基聚芳醚酮在低剪切速率区（10－2－10s－1）的流变行为及其分子量与玻璃化转变温度的关系。结果表明，样品的粘流活化能随分子量的增加而增大，Tg随分子量的变化是二个线性区，其交点值与所求的样品的临界分子量值相对应。利用测得的零剪切粘度值（η0）首次求得了PEK—C的临界分子量值。同时也讨论了Mc与温度及η0和Tg与分子量的关系。

The influence of background absorption on Co 240.7 nm could be completely eliminated when Au 242.8 nm was used as a background correction line,and the results of the determination of micro-amount Co in iron and high-alloy steel with standard addition method were satisfactory.

火焰原子吸收法测定钴是常用方法［1，2］，但需用不含钴或已知钴含量的纯铁做工作曲线，在有些样品中钴含量很低，很难找到合适的纯铁，用基准纯铁价格又很贵；而对于高温合金，合金元素含量很高，很难使标准曲线与样品基体一致。

The properties of light-adapted and dark-adapted BR D96N films and their transformation mechanism were studied by measuring and analyzing the kinetic absorption spectra of the sample under light illumination.

通过对菌紫质D96N基因突变形成的薄膜样品在光照下动态光谱的测定和分析，研究了此样品的光适应型、暗适应型特性及其之间的转化机制。

Therefore, applies dark-field imaging technique to capture images to solve the problem. It is divided into pattern matching and surface defect detection. In the pattern matching, we applied the Blob method to extract the characteristic of the words, and we used Euclidean distance to match the characteristics, recorded the position of the word.

在影像处理分析部份，分成样品比对与表面瑕疵侦测，在文字侦测是以影像连结体为主来萃取文字的几何特徵，且透过欧式距离来做特徵比对；至於图案则采用两阶段式搜寻方法与三步搜寻法来找出最相似区块，最后并记录样品比对后之位置。

With either method, first dissolve or suspend 10.0 g of the specimen if it is a solid, or 10 mL, accurately measured, if the specimen is a liquid, in pH 7.2 Phosphate Buffer, Fluid Soybean–Casein Digest Medium, or Fluid Casein Digest–Soy Lecithin-Polysorbate 20 Medium to make 100 mL.

不管使用哪一种方法，首先将10.0g固体样品或精密量取的10mL液体样品，放入pH 7.2的磷酸盐缓冲液，或液体大豆酪蛋白消化物培养基，或液体酪蛋白消化物-大豆卵磷脂-聚山梨酯20中，制成100mL的溶液或悬浮液。

The electrochemical experiments indicated that the surface modification decreased the polarization of MnO2 electrodes, increased the discharge potential, the discharge capacity and cycle stability, which is probably due to the increase of the diffusion coefficient of protons after surface modification.

与纯MnO_2样品相比，添加Bi和Bi_2O_3的样品显示了较大的放电容量和较好的循环稳定性，且放电容量随着Bi含量的增大而增加。

The CV curves in 10 cycles are nearly all the same without any change. The initial discharge capacity of the product is 117mAh/g and its discharge potential plateau is 3.2~3.3V, which could be comparable to that made by the decomposition of ferrous oxalate under the same conditions.

循环伏安测试发现样品在10周内基本上无变化，产品的首次放电容量为117mAh/g，放电电压平台为3.2~3.3V，这与传统的草酸亚铁分解法在同样的条件下所得样品具有可比性。

Two dominate variation trends are distinguished in the data plots of compressional-wave velocity versus Possion ratio, indicating the effects of mud content and calcite cement on the elastic properties of sandstone samples. In each change trend, with the rock texture transfering gradually from grain-supporting to matrix-supporting with increasing mud and calcite cement content, the propagation of elastic wave also changed from grain-to-grain contacts to rock matrix, which resulted in the measured data illustrating extremely different tendency. It helps utilize the physics properties of reservoir sandstone to extract rock texture and diagenesis properties in the research area.

样品在纵波速度－泊松比交汇图中表现出两种主要变化趋势，分别对应泥质与钙质胶结物的影响；在每个变化趋势中随泥质含量与钙质胶结物含量的增加，岩石结构从颗粒所构成的骨架支撑逐渐表现为基质支撑，弹性波能量的传播也从通过颗粒接触边界转变为通过岩石基质传播，这是使砂岩样品测试结果表现出两种截然不同变化趋势的主要原因，为利用岩石物理特性从地震资料中提取岩石结构、沉积与成岩特征的信息提供了依据。

The samples before and after annealings are analyzed by the photoluminescence .

对所制备的样品薄膜在氮气气氛中分别采取了快速退火和慢速退火处理，并对退火前后的样品进行了光荧光分析。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.
