It will take about six months for an answer , maybe seven months … the boats are not fast in india . " he has no conception of time at all , the little duck 这家伙一点儿时间概念都没有，有时我问他睡得好不好，他便说， ”哦，好，安德里，睡得好极了… …有时候我三天睡了九十二个钟头。 ”
2 ) metaphysical approach . the researcher ca n ' t consider the social necessary labor - time as a varied and diversified integration . 3 ) non - marxist approach to read on capital ( 2 )研究方法形而上学，这使研究者不能把马克思论述的社会必要劳动时间概念看成是一个不断变化的、形态多样的卜虔蒙一汰上主j斗十于整体。
After a gust of fanatical boast on the venture capital , the burgeoning ec was subjected to being attacked in the pessimistic conditions that ec ca n ' t provide a profitable model tardy as what people had expected 经过风险资本的一轮狂热吹捧，新生的ec在迟迟(风险资本家们的时间概念)找不到赢利模式的悲观前景下，开始饱受打击。
Because authentication is apart from data transpoart later and the authentication has no time stamp or nonce , when received information the bluetooth device does n ' t tell from the information is new or out of date . so authentication is easy attacked by so called middle man . we may solve this by introduce time idea at authentication . one is operate the bluetooth device address and bluetooth clock and take the value as bluetooth device , the other is start a timer at authentication 由于鉴权过程和后面的数据传输是分开的，同时鉴权过程又没有时间戳或现时，蓝牙设备收到信息后不能辨别所收到的信息是新的信息还是过时的信息，所以鉴权过程易受“中间人”攻击。可以在鉴权过程中引入时间概念，一是将蓝牙时钟与蓝牙设备地址进行某些操作，操作后的值作为鉴权时的蓝牙设备地址输入；二是在鉴权开始时启动定时器。
The main researches are the following : on the basis of . in - depth understanding of space - time concepts and change types , analyzing existing temporal conceptual models , a event - based temporal model and a process - based temporal model have been developed . combining the two temporal models with field - based spatial model and object - based spatial model directly leads to four spatiotemporal conceptual models , which are field - event spatiotemporal conceptual model , field - process spatiotemporal conceptual model , object - event spatiotemporal conceptual model , and object - process spatiotemporal conceptual model 在讨论了各种时空变化类型后，论文对已有时间概念模型进行了分析，提出时空数据建模的基本目标是表达时空变化，并就此提出根据表达离散变化和连续变化的需要，时间概念模型可分为基于事件和基于过程的模型，并结合基于场的和基于对象的空间概念模型，提出时空概念模型可划分为四种：场事件时空概念模型，场过程时空概念模型，对象事件时空概念模型，对象过程时空概念模型。
Based on this theory , a conception about flight path dynamic prediction and arithmetic which named adaptive a - p filtering with faking acceleration revising in the spherical coordinate is then presented in this paper , and write code on the real - time operating system which called vxworks . many simulations proved the value of adaptive a - p filtering . the application of flight path dynamic prediction in improvement of multitarget tracking performances is also studied and an application example is given 在此基础上，结合工程实际，通过引入航迹动态预测时间概念，笔者提出航迹动态预测方法和球坐标系下带伪加速度修正的-自适应滤波算法，并且在vxworks操作系统上编程实现；通过大量的仿真工作，验证了带伪加速度修正的-自适应滤波算法的应用价值；同时，还对应用航迹动态预测的多目标跟踪性能进行了深入的讨论，得出了航迹动态预测方法在多目标跟踪中的实践意义。
Voice conversion , as a important part of speech signal processing , is a method which transforms the source speech to converted speech with character information of target speaker , and in voice conversion , the semantic content and environment information of source speaker are remained . voice conversion refers to signal processing , artificial intelligence , acoustics and other fields . it is a typical creature of subjects crossing and has closely relationship with speech recognition , coding , and synthesis , as well as there is resemblance between voice conversion and speaker verification / recognition 研究表明,在线性多变量回归的改进实验中,由于引入了时间概念,使男声-女声的转换平均时间修正度约为21 . 1 % ;在多项式回归、线性多变量回归和支持向量回归的对比实验中,多项式回归在男声到男声的转换和线性多变量回归在女声到女声的转换中,出现了频谱距离增大的现象,而支持向量回归方法使所有的转换语音都具有更好的目标倾向性。
