查询词典 stigmatic

Based on the aberration theory of AWG, a new-type flat-field AWG is designed. The focal signals of all wavelengths of operation are focusing along a straight line perpendicular to the propagation direction. Three stigmatic points restrain three dominant geometry parameters. Furthermore, a new-type flat-field wavelength router with both flat input field and flat focal field is also designed.

基于阵列波导光栅的像差理论，利用三个无像差点约束三个主要结构参量，设计了新型平场聚焦阵列波导光栅，使得所有工作波长的输出信号都聚焦在与光束传输方向垂直的直线上，并进一步将其拓展为同时具有平输入场和平聚焦场的新型平场波长路由器。

Stamens 1 or 2 × as many as sepals; filaments short, slender; anthers basifixed, mostly oblong or linear, 4-loculed, dehiscing by slits, antisepalous anthers sometimes somewhat longer than antipetalous ones; pollen grains shedding at 3-celled stage. Ovary inferior, 1(or 2)- or 4-celled, septa solid or practically absent (present only at base and apex of ovary); styles as many as sepals, alternisepalous, free, mostly short, grading into globose or subulate stigmas, spreading in fruit; stigmatic papillae hairlike; ovules as many as styles, rarely 1, apical, pendulous, anatropous.

雄蕊1或2 *同数萼片；花丝短，纤细；花药基着，通常长圆形或者线形，4室，纵向开裂，对萼花药稍比对瓣花药长；花粉粒在3室的阶段散落子房下位，1(或者2)或4室，隔膜实心或几乎无(只在基部和子房先端存在)；花柱和萼片同数，与萼片互生，离生，柱头乳突毛发状；胚珠与花柱同数，很少1，顶生，倒生。
