Observation using transmission electron microscopy found the irreversible centripetal movement of chloroplasts in chlorotic plants, as a result occurred in three sequential events:(1) chloroplast positions changed from face position (with long axis of chloroplasts at the cell walls perpendicular to light ray) to profile position (with long axis chloroplasts near the cell walls parallel to light ray),(2) chloroplast shapes changed from long elliptical to circular,(3) chloroplasts were separated from the cell wall and moved to the center of the cell.

透射电镜观察发现失绿叶片中的叶绿体发生不可逆的向心运动，整个过程大致经历以下几个阶段：(1)叶绿体从叶绿体长轴垂直于光线转变至叶绿体长轴平行于光线；(2)叶绿体的形状从椭圆形转变为圆形；(3)叶绿体脱离细胞壁向细胞中心运动。

Choroidal neovascularization is the congenerous pathologic pattern of many fundus oculi disease. It is a sign of poor sight or blind of these disease.

脉络膜新生血管是很多眼底疾病的共同病理过程，大多病例会转化为不可逆的盲，是视力预后极差的象征。

The nautre of ester bond and sedimentary medium condition control the distribution pattern of organic acid ester in strong reductional environment and water-washed oxidized crude oils. The former features higher contents both of 9, 11-Octadecadienoic acid, methyl ester and Hexadecanoic acid, showing the non-reversible hydrolysis reaction of ester bond in condition of basicity; the later features higher contents of Hexadecanoic acid and Octadeanoic acid, and lower contents of nonsaturated and side-chain acid ester, indicating the reversible hydrolysis reaction of ester bond in acid condition.

酯键的化学性质和沉积环境中介质条件，决定了强还原咸水盐湖相和淡水湖沼相经水洗氧化次生变化的原油有机酸酯的分布特征，前者9，11-十八二烯酸甲酯与正十六烷酸为主，反映酯键在碱性条件的不可逆水解过程，后者以正十六烷酸和正十八烷酸为主，烯酸和支链酸很少，反映酯键的酸性条件的可逆性水解，烯酸经氧化向正十八烷酸，正十六烷酸转化。

The damage of rocklike materials is complex. Some mechanical model can provide satisfactory results under simple loading. A few of models (Dragon's, etc) may describe the damage evolution of quasi-brittle materials in the condition of complex loading.

Dragon等人基于不可逆热力学框架建立的准脆性材料的各向异性弹性损伤模型，可以较好地描述岩石类准脆性材料在复杂加载路径下的的应力应变响应和损伤演化过程。
