不能使用

This paper makes further research on the error,caused by use of a single step or a variable step of Runge Kutta to solve the Euler equation of quaternion method, find that the large error results from cumulated error with single step, and when using the variable step,the cumulative error is less.

结果表明，定步长时有很大的累积误差，单位四元数的"单位"性不能得到满足，而变步长有明显的改观，对一般的飞行模拟状态，都能得到较好的模拟结果，可以在实际中使用。

While you can have dialectal variations of words, you can't have abstract concepts appear as an object — like happiness, sadness or nostalgia — in any language.

However, because of the manual operation mode, which makes dataread and record randomly and trustlessly, and the diverseness of the detector'scapabilities, the current detecting ways for the train tail devices can't confirm theusing devices well worked. Making sure the reliability of the train tail devices andimproving the working safety have been an urgent problem to be resolved.

但现有的列尾装置检测，均由人工手动完成，读数、记录、随意性强，可靠性低，更由于现场检测人员业务素质参差不齐，责任心有高有低，不能保证投入运行的列尾装置均能正常使用，因此，如何确保列尾装置的可靠性，提高行车安全，已成为急迫需要解决的一个问题。

Physicists--- In their book Fashionable Nonsense (published in the UK as Intellectual Impostures) the two physicists Alan Sokal and Jean Bricmont have criticized falsifiability on the grounds that it does not accurately describe the way science really works.

简单说，那文字的意思是：两位物理学家Alan Sokal和 Jean Bricmont 指明，波普尔根本就没能确切说明科学是如何工作的，譬如，在物理学领域，某理论能使用，不是因为它的失败，而是因为它的成功。

User can not say that in these parts is not right on the money, after all, the assembly can not be unlimited budget computer additional, different people focus on the pursuit of varied, and some properties of the pursuit of game, some pay attention to mass storage, and some would like to to the limits of overclocking, and some require benefits to save money, some want to power-saving environmental protection; but the configuration is up to the application of university students and the general quarters of home entertainment applications, for these friends, the configuration of the performance and cost-effective over-the pursuit of , will result in the use of drop in comfort.

不能说网友在这些配件上省钱是不对的，毕竟组装电脑的预算不可能无限追加，不同的人追求的侧重点也各不相同，有的追求游戏性能，有的讲究海量存储，有的想要极限超频，有的要求省钱实惠，有的想要省电环保；但最多的配置是大学生宿舍应用和一般家庭娱乐应用，对于这些朋友来说，配置中对性能和性价比的过分追求，就会造成使用中的舒适度下降。

The LAB series bonding agents (modificating of alcohol amine complexing with boron trifluoride),the hydantoin and triazine series bonding agent BA603 and the borate ester bonding agent BAG-5 can effectively raise the mechanical properties of the high-energy four groups HTPB propellant when complexing with MAPO,but they can not meet the require- ments of the engine use.

改性醇胺和三氟化硼的络合物LAB系列键合剂、海因三嗪类键合剂BA603与有机硼酸酯键合剂BAG-5在与MAPO复配用于高能丁羟四组元推进剂中，能有效提高推进剂力学性能，但都不能满足发动机使用要求。

Object: Cai Daotong of adviser of assistant dean of courtyard of law of Nanjing Normal University, doctoral student thinks, Whether to form violate copyright crime, the key is in looking to whether evidence supports them to be hanged outside game, duplicated the part that can fasten from adult in game program source code, and according to this case details of a case, direct, old of two people outside hanging is only outside those who hang port join, not be duplicate, also not be to issue, existing evidence is indemonstrable also they use outside hang with ' hot-blooded legend ' the nucleus of game is identical.

反对：南京师范大学法学院副院长、博士生导师蔡道通认为，是否构成侵犯著作权罪，关键是看是否有证据支持他们在游戏外挂中，复制了游戏程序源代码中能够自成体系的部分，而根据本案案情，董、陈两人的外挂只是外挂端口的衔接，不是复制，也不是发行，现有证据也不能证明他们使用的外挂与'热血传奇'游戏的核心程序是相同的。
