只有两根琴弦的二胡的演奏手法十分丰富，左手有揉弦、泛音、颤音、滑音、拨弦、轮指；右手有连弓、分弓、顿弓、跳弓、颤弓、飞弓、碎弓等。

The longest time was 22 months.the shortest time was 12 months. Conclusion The extraction planing of missing the first molars in class Ⅰmalocclusion is different from routine extraction mode.This clinical study indicated that it should chose nimble planing and for decurtate treatment time,according to arch crowding, profile and existing of the third molars.

第一磨牙缺失的患者在I类错牙合畸形中的拔牙模式有别于常规，要根据患者牙弓的拥挤程度，面型突度及有无第三磨牙等情况选择治疗计划和有利于缩短疗程的矫治方法。

The position of string nock point of recurve can directly affect the archery s dynamic equilibrium and arrow s swing range , its balance and targeting rate.

箭巢位置的确定将直接影响反曲弓的动态平衡稳定性和箭杆离弦后箭杆尾部的摆动幅度，并最终影响箭杆的飞行稳定性和射箭命中率。

The results indicate that the thyroid gland of grey mullet is dispersedly distributed in the region of the arteria branchialis afferens of the first to the third pair of branchial arches. The monolayer follicle epithelial cells around a follicle were squamous shaped or cuboidal shaped, indicating an asynchrony of cellular activity in a follicle. The scale of the two shapes of cells differed significantly among developmental stages.

结果表明，鲻鱼甲状腺滤泡分散地分布在第1对至第3对鳃弓的入鳃动脉之间；构成同一滤泡的单层上皮细胞呈扁平形和立方形两种形态，反映出同一滤泡中上皮细胞生理活动的不同步，且发现不同发育时期的鲻鱼这两种形态细胞的比例有显著差异。

The original compound bow was designed to eliminate this problem, offering the shooter more time to aim and release the arrow.

原来的复合弓的目的是要消除这个问题，提供了更多的时间射击的目标和释放的箭头。

But this may move the shoe's flex point toward the middle of the shoe, near your arch, rather than at the ball of the foot, where your foot naturally bends.

但这样可能会使鞋的弯曲点移到鞋的中部，接近足弓的位置，而不是跖球部（就是大脚趾关节的底部位置），它是你的脚自然弯曲的地方。

Under the proper leaders, a group of centaur armed with greataxes and longbows would make short work of those ill equipped to defend themselves.

在正确的领导人的指挥下，一群武装有巨斧和长弓的半人马将使那些软弱的造物无力保护自己。

The objectives of the present study was to examine sequence variation in a portion of the mitochondrial NADH dehydrogenase subunit 1 gene (pnad1) within and among Toxocara canis, T. cati, T. malaysiensis, T. vitulorum and Toxascaris leonina, and to study their systematics and population genetics.

本研究旨在对弓首属犬弓首蛔虫、猫弓首蛔虫、马来西亚弓首蛔虫、牛弓首蛔虫和狮弓属狮弓蛔虫线粒体DNA中烟酰胺脱氢酶亚基I（nad1）基因部分序列（pnad1）进行比较研究，分析它们之间的序列差异和种群遗传关系。

Methods Genomic DNA from 61 samples of ascaridoid nematodes (Toxocara canis, Toxocara cati, Toxocara malaysiensis , Toxocara vitulorum and Toxascaris leonina) were collected from different geographical locations.

方法抽提61个弓首属蛔虫(包括犬弓首蛔虫、猫弓首蛔虫、马来西亚弓首蛔虫和犊弓首蛔虫)和狮弓蛔虫虫体的总DNA，用PCR方法扩增mtDNApnad4，然后用SSCP技术和DNA测序对序列进行分析研究。

Heart malformation, such as PTA, DORV, VSD and aortic arch malformation, were detected when neural crest were taken out before they migrated into 3, 4, 6 pharyngeal gland. Interestingly, the types of malformation were related with the length of neural crest destroyed; PTA was detected if the length exceeds two somites, while DORV would be detected if the length less than two somites. These results indicate that CNCCs are very important to the conotruncal development.

研究发现，如果在迁移之前切除散发到第3、4、6咽弓的神经嵴细胞，就会出现永存动脉干、主动脉骑跨、右室双出口、主动脉弓畸型和室间隔缺损等心血管畸形，且切除的长度与畸形的种类相关，如切除长度大于两个体节可产生永存动脉干，切除长度小于两个体节则产生右室双流出道，由此可见，心脏神经嵴细胞对于心脏圆锥部的发育意义重大。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
