在包体内部或包体与寄主岩的边界均见有钾长石及斜长石捕虏晶，这种捕虏晶是包体岩浆从寄主岩岩浆中捕获的，常被熔蚀成筛状或浑圆状。

When secondary building units characteristic of zeolite Beta detected by FT-IR appeared in the reaction mixture in the absence of crystals of zeolite Beta, the pre-treatment was terminated. The aluminosilicate gel with seconding building units characteristic of zeolite Beta was led to ordered-channel hexagonal mesoporous molecular sieve by the interaction between liquid-crystal micelles formed by the self-assembly of surfactants and pre-treated alumiosilicate gel. Therefore, the mesopore wall of SBU mesoporous materials showed the structural character of zeolite Beta.

当反应混合物出现用FT-IR可以检测到的Beta沸石次级结构单元且又没有生成Beta沸石晶体时，即刻终止预处理过程；然后利用表面活性剂超分子自组装形成的液晶胶团与经过预处理的无机物种通过界面作用把含有Beta沸石次级结构单元的无机物种导向为有规整孔道结构的六角中孔分子筛，这种SBU中孔材料的孔壁因而具有Beta沸石的结构特征。

In accordance with characteristics of cereal, crutches of sieves and combination wags of sieve were selected.

依据谷物的特性合理选择了筛面结构和筛面的组合形式，分析确定了筛孔直径和其它结构参数。

The settling may after joining the TE buffer solution (10m-MTris-HCL lmMEDTA, pH8.0) on the molecular sieve live in the protein, goes to RNA; May also use the ultracentrifuging to go to the protein to occupy, goes to RNA, goes to level shape DNA or the DNA fragment.

E.coli→用溶菌酶去细胞壁→用表面活性剂如SDS、Trit X-100等EE细胞膜→用乙酸锅使DNA、RNA及蛋白质大部分沉淀(90%以上)。

Wherever we go, we are still being winnowed and sifted. In all countries God's people are being tried "like as corn is sifted in a sieve."

无论我往那儿去，我们都要历经考验与筛选；在各邦，上帝的选民都要像麦穗经过打谷机。

Have known concave-convex soil of landed estate and the new model compound adsorption driers taking the person as raw material such as Anhui Ming Guang , Jiangsu Xuyi, local concave-convex structure and water absorption function, think that concave-convex soil has but is H2 , N completely compared with zeolite molecular sieve, 2, O 2, air waits for the inactive gas adsorption drier.

了解了安徽明光、江苏盱眙等地产凹凸土及以其为原料的新型复合吸附干燥剂，凹凸土的结构和吸水性能，认为与沸石分子筛相比，凹凸土完全有可作为H2、N 2、O 2、空气等惰性气体的吸附干燥剂。

Authors designed four mixtures of dense-graded asphalt stabilized macadam base with the method recommended by Technical Specifications for Construction of Highway Asphalt Pavement, Superpave design method, coarse aggregate voids filling method and Bailey method separately, and determined the pavement performances of asphalt stabilized macadam base mixture under the optimal oil-stone rate which include resistance capacity to vertical deformation and fatigue. Then, four design methods were compared and appraised. Based on the above study, a new asphalt-stabilized macadam base mixture gradation design method-five control sieve design method was put forward.

分别采用现行规范推荐法、Superpave法、主骨架空隙体积填充法和贝雷法设计了4种密级配沥青稳定碎石基层混合料，然后采用力学指标设计法确定了所设计的4种级配沥青稳定碎石基层混合料的最佳油石比，并对最佳油石比下的沥青稳定碎石基层混合料进行了抗永久变形性能和抗疲劳性能等路用性能的研究；根据设计过程和设计结果对4种级配设计方法进行了比较评价，在此基础上提出了新的密级配沥青稳定碎石基层混合料的级配设计方法－五控制点级配设计方法。
