Faecalis, thereby improving treatment results in endodontics and give a reference to clinical application, In this research , using traditional Drug formocresol and the current most respected calcium hydroxide (calcium hydroxide mixed with propylene glycol) as the conventional control,we investigated the antimicrobial activity of Chinese herbs cinnamic aldehgd and Chinese gallnut against E.

上述两种中药都具有很强的抗菌作用，更重要的是它们作为中药具有较传统消毒药物—甲醛甲酚、樟脑酚毒副作用小的优点，本研究通过离体牙根管消毒实验，并用传统消毒药物甲醛甲酚及当前最受推崇的氢氧化钙制剂做为常规对照，对两种中药的抗粪肠球菌性能进行评价，以期探讨更有效且安全的抑制或杀灭粪肠球菌的方法，提高根管治疗的成功率，为临床应用提供一定参考。

People talked learnedly about "holding" and "loosing,""steles,""reflexed bows,""56-pound bows,""backed" or "self-yew bows," as we talk about "rallies,""volleys,""smashes,""returns," and "16-ounce rackets."

人们挺有学问地讲什么"持箭"啦，"放箭"啦，"石柱"啦，"反射弓"啦，"五十六磅弓"，"背手弓"或者"整根水松木弓"等等，正像我们讲什么"连续对打"、"截杀"、"杀球"、"回球"和"十六两球拍"一样。

当时，22位绅士打一场比赛，来争夺一根银制的球杆，结果当地商人贝利。威廉。兰代尔最终夺冠。俱乐部成立之时，就接受了1754年由利斯为球会制定的13条规则。

Firstly, the developing principles of the cylindrical internal helical gear are proposed through analyzing the movement and geometry requirements, which provides continuous contact between the mating gear surfaces. The tooth surface of the internal helical gear in the new gearing can be imagined as being generated by the normal section of the conjugated surface of the ball-tooth, moving along the radial projection of helix line of the tooth-root circle. Also, the proposed surface can be approximate tangent to the conjugated surface of the ball-tooth along a spacial curve.

首先，通过分析保证行星轮作螺环运动时与内斜齿轮实现连续啮合传动的运动和几何条件，提出了圆柱内斜齿轮齿面的两种形成原理：即由球齿运动包络曲面的法截面沿其齿根圆螺旋线在径向的投影进行拓展所形成的内齿面，以及与球齿运动包络曲面呈近似相切接触的等螺距齿面构成的内齿面。

Plants involved in this association are most of the terricolous plants. The fungi related are classified in six genera of order Glomales, they are Glomus, Sclerocystis, Acaulospora, Entrophospora, Gigaspora and Scutellospora.

参与丛枝菌根形成的植物是大多数的陆生植物，参与丛枝菌根形成的真菌是隶属于球囊霉目6个属的真菌，即：球囊霉属、硬囊霉属、无梗囊霉属、内养囊霉属、巨孢囊霉属和盾巨孢囊霉属，它们共同的典型特征是在宿主根皮层细胞中能够形成树状的分支，即丛枝。

At present study we show that aseptic flask grown plantlet of Cyrtopodium paranaese and Mormodes Jumbo Odin × Catasetum expensum can form "rootball" spontaneously at root tips and root middle parts under no influence of hormones, and then regenerate into plantlets.

吾人研究发现曲足兰与妖精兰×瓢唇兰在组织培养下，不需荷尔蒙就自然会在根的尖端或是中间形成类似原球体构造的组织，再发育成为完整的植株，此种现象在曲足兰园艺栽培上已有记载并称之为根球。

The space between the two goal posts is color coded, and the closer you are to splitting the uprights down the middle, the more points you'll earn.

在两根球门柱之间有颜色代码表示着不同的分值，将球射的越高越靠近中间就可以获得越多的积分。

I am sure after a few weeks of adaptation and familiarization I will have no difficulty in functioning on a daily basis in an English speaking society or in participating fully in graduate studies.

在大学的三年的学习生活不仅给予我自身的充实，更重要的是磨练和培养了我较强的自觉能力和严谨，踏实的作风以及不怕困难的精神，对未来充满了信心！

As the first volcanoes erupted, one of the gases that bellowed out was steam.
