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。

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。

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 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。

The results showed that grassland and farmland were the main land use types of research area with obvious reciprocal transformation. Grassland was mainly transferred to farmland in 1975-1990. Farmland was chiefly converted to grassland, and grassland tended to increase in 1990-2004. The landscape diversity in the study area rose with the contagion index decreasing and fragmentation degree being intensified during 1975-2000. The advantageous patches maintained good connectivity with the increasing patch cohesion index and the decreasing landscape fragmentation during 2000-2004. The change of human interference intensity played an important role on the variation of land use structure. Land use intensity was mainly affected by the changes in population as well as national land use policies. In the following 20 years, the agriculture land area would tend to decrease, the grassland and unused land area would have a slight reduction by contrasting the increasing the forest land area notably.

结果表明，近30 a来，草地和农业用地面积在该研究区占居主导地位，并且它们之间发生着明显的相互转化。1975－1990年，草地主要向农业用地转移，1990－2004年农业用地主要转化为草地，草地面积增加；1975－2000年，研究区景观多样性升高，蔓延度指数下降，破碎化程度加剧；2000－2004年景观内优势斑块具有了很好的连接性，聚集度增大，整体景观格局破碎化程度降低；人为干扰强度的变化对土地利用结构的变化具有重要作用，土地利用强度主要受人口数量以及国家土地利用政策的影响；在未来20 a间农业用地面积会继续减小，草地、未利用土地面积将有小幅度降低，林地面积会显著增加。
