The HT7248FFi Focus Free Intensifier camera includes a snap-on cover that converts the housing from standard dark gray to white. The camera provides 540 lines of color resolution and is tamperproof and weatherproof.

具体型号为HT7248FFi，防护罩外壁颜色可调，深灰和白色之间可切换，提供540TV线的彩色分辨率，具有防水、防破坏功能。

The smaller ones are ca 70 nm wide and join the tectum and the larger columellae. These larger ones appear to be composed of several 70 nm in width rods. They join the distal surface of the foot layer. The proximal surface of the foot layer is marked by a white line (referred to as a junction plane) where it joins the endexine.

柱层中有种大小同的柱体，较小的宽约70 nm接盖顶层和较大的柱体，而较大的柱体是由多个宽70 nm的棒物所组成的，它们会和基层末端相，而基层顶端表面有著明显分布的白线特徵，就好像是它与外壁内层的接合面。

The main results were as follows:①The genomic DNA extraction method from TCK/TCT teliospore was established, which include cell wall lysis of teliospore by alkali solution, destroying teliospore cell wall for releasing nucleic acid from cytoplasma membrain and elimination of the PCR inhibitors such as pigments or polyphenols component.

论文主要研究结果如下：①优化了碱裂解法破冬孢子外壁-CTAB破坏原生质体，释放核酸-微量DNA过滤柱去除色素、多酚等PCR抑制物质的TCK/TCT冬孢子提取方法，排除了冬孢子细胞壁难破DNA难以提取，三甲胺、色素等PCR抑制物质导致假阴性的难题，采用此方法提取的腥黑穗菌DNA完全适用于PCR扩增。

The cells of the annulus are thickened except on the outer wall, so that they contract on drying out.

由于环带细胞的外壁增厚，因此在干燥时会收缩。

Pollen morphology of 5 species in genus Tillandsia were observed by standard electronic modules. The results revealed the common features in their shape: i.e l-colporate and reticulate exine. All these showed that genus Tillandsia plants were more advanced in evolution than the other species within the same taxa.

在扫描电子显微镜下观察了5种铁兰属植物花粉的微形态，结果表明：铁兰属植物花粉的微形态具有一定的共性，即都具有1个萌发沟，花粉外壁都具网纹纹饰，说明铁兰属植物是自然类群中较进化的类群。

Furthermore, the paper uses the pyrology calculational formula to estimate the temperature of torpedo cars body inside and ektexine. It also provides significative results and concretes analysis methods.

利用热工理论计算公式对混铁车罐体的内衬及外壁温度进行了估算，给出了一些有意义计算结果，并提供了具体的分析方法。

There are four kinds of exine ornamentation, namely baculate, tuberculate, verrucate and pilate.

外壁纹饰有4种：棒状、瘤状、疣状和鼓槌状。

In the leaves of Liriodendroideae, some of the abaxial epidermal cells are papillose and the vascular tissue of the main vein appears to be separated. However, papillose were not found and there are uniseriate, multicellular or unicellular hairs distributed on the epidermis, and the vascular tissue of the main vein appears to be continuous in the leaves of Magnolioideae. Furthermore, in the Magnolioideae, the structure of the leaves of plants in Manglietia are different from that of Magnolia.

结果表明：鹅掌楸亚科和木兰亚科在叶的结构上的主要区别是鹅掌楸亚科两种植物叶的部分下表皮细胞呈乳突状，且整个细胞外壁只形成一个乳突，而在木兰亚科的植物中有单列多细胞或单细胞的表皮毛，未发现乳突；鹅掌楸亚科植物的叶主脉维管组织环分隔呈束状，且其外包被的纤维也排列成束状，而木兰亚科的80种1亚种植物中，叶主脉维管组织连成轮状，其外面也由一圈连续的纤维环所包围。

It is the first time that these phenomena were observed: Two nuclei are surrounded by plasma and locate at the central of the female gametophyte and the others nuclei are positioned at the fringe of the female gametophyte; Before the pollen tube enters the female gametophyte. the nuclei in chalazal end begin splitting of plasma and form multinuclear cell.4. The pollens of Gnetumc are spherical or applanate with single aperture. The ornamentation of exine is spine. The basis part of spine is lenience and the top part of spine is tip or obtuse sphere.

首次在买麻藤属植物的雌配子体中观察到2个游离核位于配子体的中央位置，且被一团原生质所包围的，其余的游离核位于边缘的现象以及花粉管进入雌配子体前，合点端的核已经发生胞质分裂形成多核细胞的现象 4、买麻藤的花粉近球形或扁平型，有单萌发孔，外壁表面具小刺状纹饰，小刺基部宽大，末端尖或钝圆。

The exine of all species can be distinguished by itstectum, baculum and foot-layer.

透射电镜下观察，5种植物花粉外壁均可分为覆盖层、柱状层和基层。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
