角锥状的

2According to requirement of suppressing stray light in two-mirror system, vertex coordinate formulas of inner baffle are deduced based on geometrograph in the case of certain obscuration, viewing field and vignetting. In order to reduce the obscuration, conical baffle of secondary mirror is ameliorated into a shutter one. Outer baffle is designed when angle of stray light suppressing is foregone and the vanes are designed in C-language program. Finally, the same-height vanes in drawtube between primary and secondary mirrors are designed for further suppressing the stray light in two-mirror system.

给出双反射系统杂散光消除设计的具体要求，结合作图法，推导出考虑视场大小及初始中心遮光比确定时，主次镜内遮光罩顶点坐标公式；讨论考虑渐晕时主次镜内遮光罩的设计；为了减小初始中心遮光比，将次镜锥状遮光罩改进为百叶窗式结构；设计在杂散光源抑制角已知时的外遮光罩，并利用C语言实现程序化设计其挡光环的方法；设计主、次镜间镜筒内壁上等高挡光环，进一步抑制双反射系统的杂散光。

Linked quadrilateral pyramid and hexangular pyramid as a precursor nucleus,two new microcrystals of silver bromoiodide were prepared.

本文研究了用连体四角锥碘化银为晶核制备类似于四面体碘溴化银微晶和用六方角锥碘化银为晶核制备片状碘溴化银微晶的方法，并对两种不同微晶的结构，形态和性能进行了比较和分

Inflorescence spikelike, cylindrical, composed of spiny or bristly deciduous burrs arranged along an angular, often sinuous rachis; burrs sessile or with an obconical basal stipe, each composed of 1 or more sessile spikelets surrounded by an involucre of spines and bristles; bristles flexuous or more often spinous,± flattened, grooved on the outer face, united below, the degree of union varying from a small basal disk to a deep cupule, inner spines or bristles often ciliate around spikelets. Spikelets lanceolate, acute; glumes unequal, shorter than spikelet, lower sometimes suppressed; lower floret membranous, staminate or neuter; upper floret firmer, protogynous.

花序穗状，圆筒状，由落叶的毛刺沿着一具角安排的具刺的或具刚毛，通常波状的轴组成；毛刺无梗或具基部的倒锥状柄，每一个由1无梗或更多组成以总苞的刺和刚毛包围；或更多的刚毛曲折通常spinous，多少扁平，在外面上具凹槽，下面的合生，协会的度从一小的基部的花盘变化到一深的壳斗，小穗披针形，锐尖；不等长的颖片，短于小穗，降低有时压抑；更低的小花膜质，雄蕊花的或中性；坚定的上面小花，雌蕊先熟。

The cells full of crystals observed in orient tobacco were verified to be crystal idioblasts. The crystals observed by SEM were multiangle.

研究表明，香料烟株内结晶细胞是一类特化的含晶细胞，细胞内充满晶体，晶体形状似角锥状，质体等被挤到细胞边缘。

Cartoonist William Nearly describes it this way your feet and hands are attached but your upper body can move around the center of the bike in a cone shape when you stand you simply get a bigger cone of movement which allows you to have more control over the bike moving your body around also allows you to shift the focus point of your weight from seat to pedals to handle bars you can add weight to either wheel to improve traction for breaking climbing or turning.

漫画家—威廉描述：虽然脚和手是固定的，但可以身体却可以角锥状地活动，当你站起来可以把中心移到双脚而得到更大的角锥体移动，那会让你有更大的空间改变重心，让前后轮得到煞车、爬坡和转弯的最大抓地力。
