5通过对云南松树轮样本的年代学和气候学分析可知，在昆明地区可以利用云南松进行树木年轮研究，所建立的树轮宽度指数年表中自回归年表的敏感性较高，但去趋势序列年表反映的群体信息更多；轮宽与气候要素的显著相关关系，使利用轮宽变化的指数年表重建气候变化的历史过程具有可能性。

The distribution and the variation of the pre-stressed effective quantities in the cross section of the beam are comprehensively analyzed by the FEA along with the variation of the span numbers, span length and linear rigidity ratio of beam to column, wherefore the effect factors and the specific conclusions of lateral restraints on the pre-stressed formation in the concrete beam are drawn.

本文以竖向支承构件有一定侧向刚度的预应力混凝土框架结构为研究对象，分析了框架梁受到柱的侧向约束时的受力机理，并运用有限元数值模拟计算方法全面分析了随着梁柱线刚度比、跨度、跨数等诸多因素的变化，框架梁中预应力有效量的分布和变化情况，得到了侧向约束对框架梁建立预压应力的影响因素和具体结论。

For a bold writer full of creativity, the future undoubtedly will bring the readers more surprises and fresh feelings, but if the relationship of the old characteristic and the changing characteristic, or the changing characteristic and the flubdub can not be clearly and correctly divided, the brilliant time of prose producing can hardly be recreated and even can be immersed into the flickleness of changes.

对于一个勇于求新，敢于突破的作家来说，未来无疑将会带给读者更多的惊喜和新鲜感受，但如果不能很好处理坚守固有风格与求新求变的关系，如果不能很好的区分创新求变与哗众取宠的关系，甚至陷入为变化而变化的浮躁心态中，散文创作的再辉煌局面将很难实现。

将私人收入作为主要的链接变量，根据多部门的实际收入的变化来确定私人收入的变化。

In order to understand the changes in physiology and the storability of blueberry fruits introduced to southern part of China, and to provide scientific basis for suitable packaging materials, changes of total soluble solid content, vitamin C content, acetaldehyde content, ethanol content, protopectin content and anthocyanin content, respiration rate, polygalacturonase and pectinesterase activities, weight loss and rotted rate of blueberry fruit warn investigated. Different packaging films were used, and the storage temperature was under 2℃.

为了解引种到我国南方栽培的蓝浆果鲜果低温贮藏期间的生理变化状况，并为保鲜贮藏选择适宜的包装材料提供科学依据，研究了在2℃条件下，不同薄膜包装处理对蓝浆果果实贮藏期间可溶性固形物、维生素C、乙醛、乙醇、原果胶和花色苷的含量，以及呼吸强度、多聚半乳糖醛酸酶和果胶甲酯酶活性、失重率、腐烂率变化的影响。

Computation results show that, for the uncracked pavements, low-temperature contracted cracking is not occurred generally, but the temperature-fatigue cracking is able to occur in pavement because of cyclical temperature varying.

在此基础上，对路面温度应力以24小时为周期的变化特征进行了系统的分析，发现了初始应力对周期性变化的路面温度应力场的影响，并提出了采用多周期迭代计算解决这一问题的有效途径。

Previous studies show different interneuron changes in different models of epilepsy, which are focused on the onset of epilepsy, but not the onset of the spontaneous recurrent seizures.

在不同癫痫模型和患者海马观察含PV、CR、CB中间神经元数量变化的报道已有较多，但既往的研究着重于颞叶癫痫的始发过程上，而对颞叶癫痫发生后向自发性复发性发作演变过程中这三种中间神经元变化的研究较少。

The results showed that there were many coastal and epibenthile species, dominate fishes and crabs with significant monthly variation in composition, in the by-catch of shrimp beam trawls in waters surrounding Naozhou Island had. The average ratio of by-catch to shrimp was found to be 6.83:1 in weight and 2.5:1 in value, indicating that relatively high percentage of by-catch and less by-catch discards were the main problems in shrimp trawls.

结果表明：硇洲岛周围水域虾拖网副渔获种类多，主要为沿岸性底栖种类，组成结构存在明显的月变化，其中蟹类和鱼类是影响副渔获组成结构和月变化的优势类群；副渔获海上抛弃率很低，兼捕现象严重是现阶段虾拖网的主要问题，副渔获与目标虾类的平均重量比为6.8：1，平均产值比为2.5：1。

As for the students' names, neither their first nor their surnames seem to have changed much: there are Ndhlovus, Phiris, Nyirendas and Bandas galore, preceded perhaps by Best, Gift, Major, Mercy or Memory, even if, on this occasion, I meet no Time, Meat or Section Eight.

至于学生们的名字，不管是姓还是名，都没有多大的变化。姓还是尼德赫洛沃斯、菲利斯、尼维任达斯、班达斯等，名字多为贝斯特、吉佛特、梅杰、莫西或迈莫里。不过，这次我没有遇见叫泰姆，密特或塞克甚·艾特。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
