For example, glass, ceramics class, such as commodities or crafts products, losses due to fragmentation, when the insured or in the life insurance on the basis W.P.A. broken security risk; hemp goods, after damp heat, caused by mildew , brought about by loss of spontaneous combustion, or in life insurance on the basis W.P.A. security risk damp heat; asbestos, cement board, marble and other building materials product category, resulting in major losses due to fragmentation, it should be in the life insurance security based on the risk of breakage.

例如，玻璃制品、陶瓷类的日用品或工艺品等产品，会因破碎造成损失，投保时可在平安险或水渍险的基础上加保破碎险；麻类商品，受潮后会发热、引起霉变、自燃等带来损失，应在平安险或水渍险的基础上加保受热受潮险；石棉瓦、水泥板、大理石等建筑材料类商品，主要损失因破碎导致，应该在平安险的基础上加保破碎险。

Paging and Registry file fragmentation can be one of the leading causes of performance degradation related to file fragmentation in a system.

另外 PageDefrag 也会显示系统档案在磁碟上的分散情况，如果碎片不是很严重的话就可以不用重整。

The main purpose is to store files temporarily ,so we can delay the time to allocate file to its original filesystem until file size is more certain to avoid file fragmentation.(2) Purpose a writeback algorithm, considering file spatial locality, to flush continuous and near blocks together to reduce writeback time.

其主要的目的是暂时储存新建立的档案，延迟档案分配给其真正所属的档案系统的时间，等到较为确定档案大小后再进行分配，以避免档案 fragmentation的情形并减少不必要的I/O；(2)修改以往以档案为单位将资料写回的演算法，加入了考虑每个要写回的block在磁碟上相对应的位置，让较连续且较邻近的资料一起写回，减少写回所需的时间

The results show that dynamical ductil-ity dominated final velocity of fragments. During tube expansion, the shear fracture appears preferentially a-long the adiabatic shear bands under positive stress, so the adiabatic shear band determines the size and shapeof fragments. Though the fragmentation behaviour of medium carbon Si - Mn bainific steel is close to that ofsteel 50SiMnVB, medium carbon Si - Mn bainitic steel is an ideal candidate material for the tubular bombs be-cause it is better in dynamical ductility, which can enable the tubes to gain high speeds before fragmentation.

结果表明：材料动态塑性是决定破片最终速度的主要因素；圆管膨胀时外表面形成以剪切为主的裂纹，并向内扩展，接近内表面的绝热剪切带伴随着圆管的膨胀而扩展，并未出现失稳现象，但在正应力的作用下成为优先的断裂通道、决定破片的尺寸和形态；中碳Si-Mn贝氏体钢与50SiMnVB钢的破碎性能相近，但贝氏体钢动态塑性很更好，破碎前的膨胀量较大、更有利于提高破片初速，是弹箭比较理想的候选材料。

Implementation of fragmentation is optional; an implementation that does not support fragmentation MUST drop any datagram whose FRAG field is other than X'00'.

分段的执行是可选择的，一个不支持分段的执行必须忽略任何FRAG区域不为x00的数据包

The poly- 2-(dimethylamino ethyl methacrylate-b- potassium polyacrylate (PDMAEMA-b-PPA) with pH and temperature response was polymerized by Reversible Addition-fragmentation Transfer.

具体的过程与结果如下：通过可逆加成-裂解链转移法(Reversible Addition-fragmentation Transfer，RAFT)制备嵌段聚合物PDMAEMA-b-PPA，分子量为24500 g／mol，分布为1.10。

The results showed that the MS2 fragmentation pathways of DASSSB were affected by the character and position of substitutes on salicylidene phenyl. The C=N cleaving to form fragmentation ion [M+H-283](superscript +) was dominant for DASSSB compounds with electron-donating group on the C4 of the salicylidene phenyl; while fragmentation ion [M+H-254] (superscript +) forming by C-C cleavage of the β-position of C=N was dominant for DASSSB compounds with electron-withdrawing group on the C5 of the salicylidene phenyl.

结果显示，这些化合物的ESI-MS/MS裂解方式与它们分子中水杨醛苯环上取代基的性质和位置有关：当水杨醛苯环上4位连接供电子取代基时，分子以CN双键断裂为主，生成[M+H-283]碎片离子；当水杨醛苯环上5位连接吸电子取代基时，分子以CN双键β位的C-C键发生断裂为主，生成[M+H-254]碎片离子。

Comparing the landscape types of 1995 with that of 2005, we find out that:①the natural arbors are decreasing, with patches more fragmentation, size more odds, shapes more complex;②the area of natural shrubberies is increasing, with patches less fragmentation, shapes more simple and formulary ,the size of patches more even;③the area of natural grasses is increasing, with patches less fragmentation, shapes of patches more odds;④the area of timbers is increasing, with patches more dominance in landscape, more connectivity;⑤the area of Eucalyptus increases, with patches less fragmentation, shapes of patches more complex , more convergence, more connectivity;⑥the area of orchards is increasing, more connectivity;⑦the patches of the rubber is becoming more assemble, more connectivity, more formulary;⑧the area of plowland increases;⑨the area of reservoirs, rivers and ponds increases, with patches more assemble;⑩the area of cities decreases, with patches more dispersing, with shape more complexthe area of countries increases, with patches less connectivity, more dispersing, with shape more complex; the patches of the rest lands are more dispersing, with shape more complex;(3)In the process of economic development in the upper reaches of the Changhuajiang river watershed, a series of the ecological environment problems have appeared because a lot of landscape function broke off, and the connection of human landscape with natural landscape decreased, which aroused by the fragmentation of natural and semi-nature landscapes increased, the stability of the landscape structure decreased, as well as stress of human disturbance, resource and environment upon the landscape increased gradually.

3昌化江上游流域在经济发展进程中，自然与半自然景观破碎度增加，自然景观结构稳定性下降，人为干扰、资源和环境对景观胁迫逐渐增大，中断了许多生态过程，导致城市等人文景观与自然景观连接度很差，产生了一系列的生态环境问题。

RESULTS The results indicated that PCF could significantly increase the viability of thymocytes and enhance the activities of SOD, GSH-Px, CAT in cells. PCF decreased the amounts of ROS and the rate of apoptosis in cells. PCF inhibited the morpholog alteration of the thymocytes irradiated by UVB and maintained the ultrastructure of cells in normal. PCF attenuated UVB caused DNA fragmentation in thymocytes. While combined ERKs inhibitor yielded typical DNA fragmentation, co-treatment of thymocytes with PCF and JNKs and p38 kinase inhibitors completely blocked UVB-induced DNA fragmentation.

结果 PCF能显著提高UVB辐射后小鼠胸腺淋巴细胞的活性；提高胞浆中SOD、GSH-px、CAT的活性，降低ROS含量及细胞凋亡率；抑制UVB辐射所致的胸腺淋巴细胞凋亡的形态学改变，维持细胞的正常超微结构；抑制UVB所致的胸腺淋巴细胞DNA片段的出现；预先应用ERK抑制剂使DNA片段增加，给予JNK和P38抑制剂后协同PCF使DNA片段带减少。
