This paper discusses the growth stages,spatial structures,quantitative fitting relationships among various parameters,growth patterns and influencing factors of mud cracks by field survey,core observation and SEM *** study shows that:(1) Mud crack growth can go through three stages,*** syndiagenetic stage,the burial diagenetic stage(including early diagenetic stage,middle-late diagenetic stage) and the epidiagenetic stage.(2) Quantitative fitting relationships among various parameters allow a great significance to describe the spatial structure,the regional distribution and the growth environment of mud cracks.(3) Mud crack growth has three models,such as the unilateral growth model including the linear growth pattern,the curvilinear growth pattern and the bifurcation growth pattern,the multilateral growth model including the inteisectional growth pattern,the join growth pattern and the dispersed growth pattern,and the mixed growth model including the combination of any patterns listed above.(4) Modern mud crack growth usually undergoes four *** beds in sand-mud rhythmic strata can play a lubricative role on crack growth and provide enough sandy deposits for filling cracks.(5) Mud crack growth usually produces bifurcation and bifurcation angles which are mostly 120° or 90° that are related to sediment heterogeneity and released energy.(6)Factors affecting mud crack growth cover many aspects:clay content and salinity can control the number of mud cracks in different areas;terrain can control mud crack morphology;and different sedimentary cycles can control the growth patterns and filling models of mud cracks.

用0.01、0.10、1.00 mg.L-1久效磷暴露金鱼21 d,测定了精巢乳酸脱氢酶(LDH)、酸性磷酸酶(ACP)、碱性磷酸酶(ALP)的活性,并观察了精巢显微和超微结构的变化。结果表明:久效磷暴露21 d,精巢小叶基膜断裂,Leydig氏细胞水肿,小叶间质扩大,支持细胞核膜溶解,胞质内脂滴和髓磷脂象数量增多。1.00 mg.L-1久效磷造成了生殖腺指数的显著下降,对精巢发育有一定程度的延迟作用。随着久效磷暴露浓度的升高,LDH,ACP,ALP的活性逐渐下降,0.10、1.00 mg.L-1久效磷暴露组精巢LDH,ACP的活性下降显著,而各暴露组的精巢ALP活性呈现不显著下降趋势。推测久效磷可能通过损伤精巢超显微结构和降低LDH,ACP和ALP活性,干扰精巢能量代谢,造成对雄性金鱼的生殖毒性。

代谢综合征是一组多种代谢性疾病的危险因素,包括中心性肥胖、血脂异常、糖代谢紊乱、高血压等在同一个体聚集的临床综合征。代谢综合征的核心成分是脂肪组织,脂肪组织除了作为能量储存器官外,还可以被视为一个动态的、复杂的内分泌器官,产生和分泌多种脂肪因子。运动对人体的新陈代谢是有益的,但运动作用于代谢综合征的机制还不完全清楚,可能与能量消耗和脂肪因子的变化有关。因此,该文选择一些代谢综合征相关经典脂肪因子,对运动调节脂肪因子可能的机制进行综述,为治疗胰岛素抵抗和肥胖提供新的思路。
