无齿

During experiment, LC50 of bleaching powder in 24, 48, 72, 96, 120, 144 and 168 hours were get; LC50 of trichloroisocyanuric acid powder in 24, 48, 72 and 96 hours were also get.

试验以洱海流域的背角无齿蚌为研究对象，确定常用鱼药：漂白粉、氯杀宁对湖泊大型底栖动物背角无齿蚌的毒性影响。

Most birds are toothless; a toothless old crone.

大多数的鸟都是无齿的；一个无齿的丑老太婆。

Other diagnostic features include the presence of a crest along the anterodorsal midlines of the premaxillae,the edentulous maxilla,the presence of a groove-like trough along with the anterolateral margin of the maxilla on the ventral surface,the presence of six conical premaxillary teeth,and no more than six conical dentary teeth which are restricted to the anterior portion of the dentary.

其他主要特征有：前颌骨沿前背中央有一隆嵴；上颌仅前颌骨有6枚圆锥形齿，无上颌骨齿；上颌骨沿前腹侧缘有一沟槽；下颌齿骨齿都集中在前端且至多不超过6枚。依据上述这些特征很易把短吻贫齿龙与其他已知海龙相区别。短吻贫齿龙头骨顶面松果孔大且很前位，头骨腭面的锄骨和翼骨均无齿，它的颈较长(至少可以辨认出13个颈椎)。

Of or belonging to the order Edentata, which includes mammals having few or no teeth, such as anteaters, armadillos, and sloths.

贫齿目的属于贫齿目的，包括无齿和少齿的哺乳动物，如食蚁兽、犰狳和树懒

Try and see: The mouse is toothless , the cattle is imperforate; The tiger has no spleen , rabbit has no lip; The dragon has no an ear , the snake has no a foot; The horse has no a gallbladder , the sheep has no god; The monkey has no buttocks , chicken has no a kidney; The dog has no intestines , the pig has no a tendon.

试看：鼠无牙，牛无齿；虎无脾，兔无唇；龙无耳，蛇无足；马无胆，羊无神；猴无臀，鸡无肾；狗无肠，猪无筋。

Results indicate that the stigmatic surface morphology of Pedicularis species is related to the type of corolla structure occurring in the species. Pollination studies in 8 Pedicularis species demonstrated adaptation between stigmatic surface morphology and other aspects of floral biology.

拥有更膨大，更粗糙的柱头表面特征的植物种类通常都是具喙或长管种类，而短管无齿种类的柱头平滑且无膨大，相反，对于长管具喙种类而言，柱头在膨大的同时，更形成了发达的"沟回"结构，这种柱头结构式样的不同直观、显著的改变了不同种类的传粉效率。

The safe concentration of Anodonta woodiana woodiana were: the available chlorine of bleaching powder of 95.25~108.86 mg/L, the available chlorine of trichloroisocyanuric acid powder of 3.32~3.55 mg/L.

试验得出漂白粉作用下，背角无齿蚌24h、48h、72h、96h、120h、144h、168h的半致死率；氯杀宁作用下，背角无齿蚌24h、48h、72h、96h的半致死率；漂白粉有效氯安全浓度95.25~108.86mg/L；氯杀宁有效氯安全浓度3.32~3.55mg/L。

The slewing bearing can be divided into four-point conatct ball slewing ring, double-row angular thrust ball slewing bearing, crossed cylindrical roller slewing bearing, crossed tapered roller slewing bearing and three-row cylindrical combined roller slewing bearing according to their different structural styles.

转盘轴承根据不同的结构型式可以分为四点接触球转盘轴承、双排角接触推力球转盘轴承、交叉圆柱滚子轴承、交叉圆锥滚子轴承和三排圆柱滚子组合转盘轴承等不同的结构型式；上述各类轴承按其是否带齿及齿轮的分布部位又分为无齿式、外齿式或内齿式等不同结构。
