无触角的

Any of various mollusks of the class Gastropoda, such as the snail, slug, cowrie, or limpet, characteristically having a single, usually coiled shell or no shell at all, a ventral muscular foot for locomotion, and eyes and feelers located on a distinct head.

腹足动物属于腹足纲的任何一种软体动物，如蜗牛、蛞蝓、海蛙或帽贝，特征是具有一单个通常是卷起来的壳或根本无壳，有为了移动的腹足、眼睛和触角生于头部一显要位置

Unicorn fish are generally nonaggressive, but during a rare fight they defend themselves with forward-pointing prongs on either side of their tails rather than the prominent horn on their heads.

麒麟鱼一般无侵略性的，但在一次罕见的打击，它们为自己辩护以前瞻性指向prongs两侧的尾巴，而不是突出的触角在它们的头部。

No difference was found in type and distribution of sensilla between the male and female adults.

雌雄个体间触角感器的类型、分布均无明显差异。

The EAG results showed that no significant difference between female and male S.bifasciatus.The EAG responses of S.bifasciatus to 3-Carene,Limonene,Terpinene and Thujopsene were increased with the concentration respecitively within the range of 1/1000-1/10.The results of "Y" tube olfactory bioassay showed the pests can be attracted by 1/100 Limonene,3-Carene and Thujopsene.Original and 1/10 Terpinene was the best. In addition,the extracts of A2 and D1 also caused positive attraction to S.bifasciatus,while the extracts by SE and SDE were non-attractive.

触角电位测定结果表明，双条杉天牛雌雄成虫对样品的EAG反应无显著差异。1/10浓度的3-蒈烯、柠檬烯、萜品烯和罗汉柏烯的EAG值最大。Y型嗅觉行为生测结果表明，1/100浓度的柠檬烯、3-蒈烯和罗汉柏烯对天牛有明显引诱效果，萜品烯则是原液和1/10浓度的引诱效果最好；α-蒎烯和β-蒎烯无明显引诱效果。4种提取方法中，改装简易蒸馏法样品(A2)和超临界CO_2萃取样品(D1)对天牛具有明显引诱作用；索氏提取物和并时蒸馏萃取物无引诱效果。

A series of modified polyurethane elastomer materials with different amino siloxane content were synthesized,which were based on polyoxypropylene glycol,aminoethyl aminopropyl poly,toluene diisocyanate and the curing agent dimethylsulfide toluylenediamine.

以聚氧化丙烯二醇或聚氧化丙烯三醇、氨乙基氨丙基聚二甲基硅氧烷、甲苯二异氰酸酯为原料在无溶剂条件下制备预聚体，利用二甲基硫甲苯二胺为固化剂合成一系列氨基硅油改性聚氨酯弹性体材料，并对材料的力学性能、耐热性、表面水接触角等性能进行了测试。

Our experimental measurements reified this new theoretical model of describing the capillary filling behavior. The dynamic contact angle depends on Oh and f Re, the capillary filling distance scales with the square of capillary filling time.

依据描述该现象的理论关系式，发现方型微流道内表面张力流毛细填充现象与动态接触角α、欧氏数Oh与无因次化参数f Re有关，藉由实验量测的方式，发现动态接触角为欧氏数Oh及f Re值的函数。

The surface and cross section of uncoated and coated Polyvinyl acetals were analyzed by microscope and SEM, results showed that, the contact angle of the coated fiber decreased in most of the areas of the fibers, the chitosan film on the fibers was thin and uniform. At the same time, there was no residual material in the coating process and the whole process was environmentally friendly.

结果表明，该方法切实可行，通过显微镜和SEM照片对涂覆壳聚糖前后的维纶纤维进行微观分析，发现在化学纤维表面形成的壳聚糖膜薄而均匀，同时增加了化学纤维的表面粗糙度，涂覆效果较好；通过接触角的变化说明纤维的亲水性得到改善；该方法还具有无残留物和对环境友好的优点。

The transformation of such 'irrelevant' concerns forms the basic narrative for Harbour and, reflecting his sensitive artistic practice, functions as a metaphor for his methodology of 'expansive imagination': a fluid, outward and boundary-less approach to contextualising the meanings behind everyday objects and the banalities of life.

这件作品构成了「海洋」的敍述基础，展示了他敏锐的艺术实践触角，并作为其扩张性想像的象徵：以流动、向外延展及无地域界限的实践方法，将存在於日常物件及平庸单调的生活背后的意义表现出来。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
