粒层

Electron photomicrographs of individual chloroplasts at very high magnification show that they contain large numbers of layered substances, somewhat resembling stacked coins. These layers are known as grana.

从高倍放大的电子显微照片上可看到单个的叶绿体含有大量的一层层的像硬币一样重叠起来的物质，这些层状物被称作基粒。

Electro microscope analysis showed that NO promoted the chloroplast development, as indicated by increased number and size of chloroplast in both the mesophyll cell and bundle sheath cell of the leaves, and well-developed stroma lamellae and grana as well as increased numbers.

电镜观察结果证实，NO促进了玉米叶片叶肉细胞和维管束鞘细胞中叶绿体的发育，叶绿体数量增多且体积增大，基质片层和基粒数量明显增多且结构完好。

An example is the internal system of lamellae in CHLOROPLASTS.

例如，叶绿体内的片层基粒结构。

Over the past six years the House Republicans have repeatedly snuffled up the sugar that had been meant to make the bitter pill of entitlement reform go down, without swallowing the hard stuff.

在过去六年当中，议院的共和党人一直在含糊其辞，试图使彻底的授权制度改革这粒苦药包一层糖衣，然后自己服下。

A fine-grained, dark gray sedimentary rock, formed from silt and clay and similar to shale but without laminations.

After 10h ball milling, the alloy of carbonyl iron and carbonyl nickel began to form, and the sample kept its original bcc and fcc structure; after 100h ball milling, the sample became a solid solution with bcc structure; after 200h ball milling, the diffraction peak of Ni almost disappeared and the isotropic grains with D achieved, which was mainly attributed to the dislocations and disclinations of the nanocrystalline bcc FeNi suffering from severe plastic deformation by ball milling.

球磨10h时，羰基铁和羰基镍开始形成合金，但大部分Fe、Ni原子仍分别以bcc结构和fcc结构存在。球磨100h时，样品以bcc结构的FeNi合金为主，球磨200h后，样品中fcc结构Ni特征峰几乎消失，FeNi纳米晶达到最小粒径的平衡值，~8nm。高能球磨过程中，晶界区域的层错缺陷是合金化和纳米晶形成的重要因素。

In this ***, Frens method was used to prepare colloidal golds with three different diameters of 20nm, 40nm, 70nm. They were prepared by controlled reduction of gold chloride with 1% sodium citrate solution according to the procedure described by Frens.

1采用经典的Frens方法，用1%的柠檬酸三钠溶液还原氯金酸溶液制备了20nm、40nm、70nm三种不同粒径的胶体金，实验结果表明20nm、40nm的胶体金比较适合做免疫层析实验。
