1.In this paper a brief introduction of Etching diffraction grating (EDG) demultiplexing characteristic is presented. The traditional constant spacing design of the EDG parameters is not suitable for the planar waveguide. Two design schemes:1 stigma method and 2 stigma method,is analyzed in detail in this paper.
本文介绍了蚀刻衍射光栅 (EDG)的解复用特性 ,对于光栅几何参数的设计 ,传统的等距凹面光栅不适用于平面波导 ,文中详细的讨论了两种无像差点设计方法 :一点法和两点法。
2.The contribution of SSE of maintainer lines to SSE of sterile lines (0.660) is greater than that of DSE(0.183). It is suggested to select maintainer lines with high percentage of stigma exterior to get sterile lines with high percentage of stigma exterior.
保持系柱头单外露率对不育系柱头单外露率的贡献(0.660)大于保持系柱头双外露率对不育系柱头单外露率的贡献(0.183),选择柱头外露率高的保持系能够选育出柱头外露率高的不育系。
3.the rate of abortive pollens was 99.97%; the outcrossed seed setting rate was 45.5%; the stigma exsertion rate was 87.1% with 56.5% of double-stigma exsertion rate.
该不育系农艺性状稳定,株型较好,不育株率达100%,花粉败育率达99.97%,柱头外露率87.1%,其中双外露率56.5%,米质优,高抗稻瘟病,配合力较好。
4.The effects of dipping flower with 2 plant growth regulators(PCPA,2,4 D)and artificial vibration pollination on the fruit development and the occurrence of grey mould of tomato in greenhouse were studied. It was found that the rate of residual petal and stigma on tomato fruit were increased significantly after dipping flower,and the petal and stigma became the major sites of initial infection,which resulted in the severe occurrence of grey mould.
在棚室中比较了PCPA （对氯苯氧乙酸） 、2 ，4?D 蘸花及人工振动授粉与灰霉病发生的关系， 发现番茄蘸花后花瓣及柱头在果实上的残留率大大增加并成为灰霉病菌的主要初侵染位点， 加重了番茄灰霉病的发生。
5.Objectives To evaluate the effect of intervention designed to decrease HIV/AIDS stigma and discrimination in the health care services, and explore an effective model of decreasing HIV/AIDS stigma and discrimination in the health care services.
目的 评价针对医务人员开展的降低对HIV感染者／疑似感染者的羞辱与歧视干预措施的效果； 探索降低医疗保健服务提供中针对服务对象存在的HIV／AIDS羞辱与歧视的有效途径和方法。
6.There is no great stigma associated with being laid off.
所以下岗并不是件可耻的事情。
7.Isolation of NBS-LRR Class Resistance Gene Analogs from Stigma cDNA of Pomelo (Citrus grandis cv. guanxi)
柚cDNA中NBS-LRR类R基因同源序列的分离
8.The pollen grain germinates on a special extension of the carpel, the stigma, and double fertilization results in a diploid zygote and triploid (usually) endosperm nucleus.
花粉粒在柱头上萌发，双受精导致双倍体的合子和三倍体的胚乳形成。
9.Cymes 1-2 in axil of leaves, rather short; flowers pale green, 7 mm in diam., 5-merous; sepals imbricate, inner two larger; petals suborbicular, 3 mm long; stamens without filaments; pistil without style, stigma appressed, minutely 5-lobed.
聚伞花序1-2腋生，短小；花淡绿色，直径约7毫米；5数；萼片覆瓦状排列，内方2片较大，边缘常有深色细浅齿；花瓣近圆形，长约3毫米；雄蕊无花丝；雌蕊无花柱，柱头平贴，微5裂。
10.During the process of fertilization, pollen lands on the stigma, a tube grows down the style and enters the ovary.
授精的过程中，花粉到达柱头，花柱低下来进入子房。
