尖端

Excied root apex explants of seedlings from Mormodes Jumbo Odin × Catasetum expensum were induced to from PLBs in MS medium supplemented with BA (0.5 mg/l ). Histological observations confirmed that root cap were disorganized at early stage and followed by vascular strand of existing roots protruding into PLBs formation.

以不同时期的根类原球体为材料经石蜡切片后发现，早期会先在根尖端形成球状突出，随著根类原球体膨大，根培植体的维管束延伸到球体之中并支撑著尖端形成芽原基，而后根类原球体顶芽长出维管束成为植株。

The results presented here demonstrate that the highly specificantibody-antigen interaction can be used to generate single-moleculemaps of specific types of molecules in a compositionally complexsample while simultaneously carrying out high-resolution topographicimaging.

为了能够在新模型中应用原子力显微镜，他们在原子力显微镜的尖端粘上针对单个蛋白的抗体。为了保证抗体探针是真正敏感的，用一个多聚物把抗体和尖端连接起来，使抗体摆动到与蛋白受体更易结合的位置。

By using a new method of corroding cathode point,we have corroded metal material most in use.

采用一种腐蚀阴极尖端的新方法，对阴极常用金属材料W，Mo，Ir，Ta制作的阴极尖端进行腐蚀。

The results show that if the initial crystal nucleus is not melted, its size has nothing to do with the simulation results. With the coefficient of interfacial anisotropic strength increasing, the dendritic tip's growing speed increases linearly, while its radius decreases parabolically. The lower the sub-cooling degree is, the more difficult it is to find secondary dendrites.

结果表明：在保证初始晶核不被熔化的前提下，初始晶核半径r0的大小不影响模拟结果；随着界面各向异性系数的增大，枝晶尖端生长速度以线性方式增大，而枝晶尖端半径以抛物线方式减小；过冷度越小，枝晶的生长越困难，越不能出现二次枝晶。

Firstly, a morphologically structured model was proposed by considering four morphological forms of the mycelia: apical compartment , subapical compartment , hyphal compartment and deactivated compartment .

首先，将菌丝分为四种形态类型：菌丝生长尖端、次尖端、代谢型的菌丝和失活的菌丝，得到形态学结构模型。

The general feature of the plastic deformation is similar in both charging or uncharging hydrogen specimens.

发现：氢的存在并不改变在Ⅰ型或混合型载荷作用下，裂纹尖端的塑性变形特征，即在主裂纹前端，应变呈不对称分布，裂纹尖端Schmid因子决定了条带状局部形变带的轴线方向。

Aiming at irregularity of a real fracture surface or a real crack profile, applying Griffith's criterion and fractal geometry, the real asymptotic expression at the crack tip is developed, and it is discovered that the fractality of the crack reduces the stress singularity at the crack tip.

5针对实际断裂面或裂缝的不规则性，利用Griffith能量平衡原理及分形几何，推导了裂缝尖端实际应力场和位移场的表达式，研究发现，裂缝的分形性减小了裂缝尖端应力的奇异性。

Under the ratios of various initial cracking relative length,height and volume of gas concrete beam,the whole curve of opening displacement s at several testing points about fracture toughness,fracture energy,and in the area of load,cracking-tip-opening-displacement,cracking tip opening displacement cracking-tip-area are researched systematically.

在本研究中对加气混凝土梁在不同初始裂纹相对长度、不同高度以及不同体积比例等情况下的断裂韧性、断裂能以及载荷—裂纹口张开位移—裂纹尖端张开位移—裂纹尖端前沿区若干测点张开位移全曲线进行了系统研究。

The model involved effect s on SERR computation by large rotation of the crack tip and variety of discrete element shapes. The method of SERR calculation at the crack tip was modified.

该模型考虑了裂纹尖端大转动和离散单元形状变化对应变能释放率计算的影响，修正了裂纹尖端应变能释放率的计算方法。
