易碎的

Easily store food broken bits inside the gums ditch, adhere to a germ spot, become the good district that the germ growth breeds, because it presents to close appearance, don't easily sweep and often cause the gum burning disease and tooth the paroxysm occurrence is for week.

龈沟内易积存食物碎屑，附着菌斑，成为细菌生长繁殖的良好区域，由于其呈封闭状态，不易清洁，常导致牙龈炎症及牙周疾病的发生。

The governing equation is the mild-slope equation. Finite element method has advantage to treat complicated boundary. The second order radiation boundary condition is expanded to improve the wave model for large incident wave angles. The validity of the second order radiation condition is examined through varying arbitrary wave incident angles.

模式将以包含波浪绕射及反射之缓坡方程式建立数值模式，利用有限元素法易於处理不规则边界的优点，引用二阶近似辐射边界条件，扩展波场模式处理大角度波浪入射的能力，探讨在未碎波的情形下，二阶辐射边界条件对於任意角度波浪入射之适用情形。

Furthermore, large-scale fold and fault structure hasn't been found around the Tianchi Lake, but the original prismatic joints and radial joints developed well in the trachyte, so the rock mass is dissected into fractured fragmental structure and the integration of rock mass is further destroyed.

在构造方面，长白山天池周围虽然没有发现大规模的褶皱断裂构造，但粗面岩中原生柱状节理、放射状节理十分发育，这些节理裂隙将岩体切割成十分破碎的碎裂结构，使岩体极易产生岩崩、落石，使岩体的完整性遭到了进一步的破坏。

The traditional separation techniques of brittle materials can not meet the high precision and high cleanliness requirements in the semiconductor industry because they are susceptible to some flaws, such as residual stress, micro-cracks, chippings on the edge.

传统分离脆性材料的技术由于易产生残余应力、显微裂纹与边部碎屑等缺陷，越来越不能满足半导体工业高精度与高清洁度的要求。

He is the most remarkable man that I have ever known.

他是我知道的人中最值得注意的人。

Increased appearance of lymphocele was noticed in patients with diabetic nephropathy, congenital malformations of the urinary tract, and inflammatory diseases, including glomerulopathy and extraglomerular ones, after high-voltage radiotherapy and after removal of the renal graft.

经过高压放射疗法和切除移植肾后，在糖尿病肾病患者、泌尿系统先天性畸形患者和炎症患者身上发现淋巴囊肿有所增加，包括肾小球病和球外疾病等。
