查询词典 systematic sample

The results show that the concave structure ameliorates the surface stress distribution of the nonsmooth sample,makes the local stress between concaves less apparently than that of the smooth sample,that means the local low stress areas are formed on the nonsmooth surface.

结果表明：在受力状态下，仿生非光滑凹坑改善了试样表面的应力分布，使非光滑试样表面凹坑间的区域局部应力明显小于光滑试样表面的应力，即产生了局部低应力区。

The near-field electrical distribution formed when the illumination light diffracts as it propagates through the sample is very sensitive to the optical properties of the sample such as geometrical structure, refractive index and absorptivity distribution.

当前近场光学显微学迫切需要解决的一个重要问题是要从理论上对近场成象过程有清楚的认识，从而为近场光学显微学中图象的正确解释及新仪器的开发提供理论依据。

The result shows: the material of glass reinforced plastic mortar pipe is brittle, the enlaced sample always destroyed along the interface of different layers, but the centrifugal sample destroyed along a breach; the capacity of bearing radial load of enlaced glass reinforced plastic mortar pipe is better than the centrifugal ones, the destroyed forms of them is also different. Secondly, the whole pipe and direct shear friction experiments between glass reinforced plastic mortar pipe and typical soil of Shanghai have been done.

结果表明：玻璃钢夹砂顶管管材属于脆性材料，缠绕式玻璃钢夹砂顶管的材质试样基本沿着层与层之间的分界面破坏，而离心浇铸式玻璃钢夹砂顶管材质试样的破坏是沿着某个滑裂面破坏；缠绕式玻璃钢夹砂顶管的抗径向荷载性能要优于离心浇铸式玻璃钢夹砂顶管，同时两者在径向荷载作用下的破坏形式明显不同。

The sample was liquated with a mixed flux of unhydrous sodium carbonat and bonic acid,soaked out with hydrochloric acid(1+5),and then the sample solution was measured by inductively coupled plasma atomic emission in system of nebulizer and torch resistant to hydrofluoric acid.

试料经无水碳酸钠和硼酸的混合熔剂熔融，HCl(1+5)浸取，在电感耦合等离子体原子发射光谱仪上，用耐HF腐蚀的雾化器和矩管系统测量。

Methods Soil was air-dried, grinded, and screened through 100 mesh sieve. Appropriate sample was put in porcelain crucible with 0.5 g Aldrin reagents, and another 2 g Aldrin was used to cover the sample. Then the mixture was burned, cooled off, lixiviated by water, and determined by arsenic-cerium redox spectrophotometry.

土壤经自然风干，粉碎过100目筛，取适量试样于盛有0.5g艾氏试剂的瓷钳埚中，再取2g艾氏试剂覆盖试样，置高温炉中灼烧，冷却，水浸提，砷铈氧化还原分光光度法测定碘含量。

Vitamin B_6 is extracted from by hydrolyse of food sample with 0.22 mol/L H_2SO_4 at 121℃ bournd forms.aliquots of each sample extract are pipetted into assay tube with Pyridoxine Y Medium.

以0.22mol／L的H_2SO_4高压水解样品，提取出待测的维生素B_6（VB_6）样液以不同的量加入吡哆醇Y培养基中。

The sample was treated with suspension technique. Turnip sample was crushed and sieved to make agar suspension.

用悬浮液技术处理萝卜样品，将样品粉碎、过筛，制备成琼脂悬浮液。

To do this, the sample is first isolated from the vacuum by means of the taps, the vacuum over the sample is then replaced with an inert gas and can then be stoppered and removed.

为了做到这点，首选将样品与真空用阀门隔开，然后将样品上面的真空用隋性气体代替，然后塞上塞子移走。

Pull up on the rod to empty the sample into an appropriate container. Or hold the valve slightly open while submersing the COLIWASA into the liquid to collect the sample from the surface down to the desired level.

拉起支撑棒把样品倒入一个合适的容器保存，或使阀门微微张开，同时吧取样器淹没到要取样的液体中收集从表面到预定的水平高度的样本。
