But take the huntin', shootin', and fishin' subtext, mix it up with a mess of tartan, stir in a stag intarsia, a hint of retro and you ended up with a distinct house-party-in-the-Highlands vibe.

但他灵感取材於打猎、射击、钓鱼等户外运动，并混合了带有乡村风格的格纹布料、拼花图案等，在在都暗示出浓厚的复古风格，并很像高地的house party般，热闹非凡。

The 3-dimension solid model of the 8th turbine rotor blade of some type aero engine is constructed in software UG, and the numerical calculation region of stream field in ECM is set up in special flow field calculation software FLUENT based on the principle of hydrodynamics. The distribution of 6-dimension forces is got after numerical calculation, and the equation between 6-dimision forces and interelectrode gap is set up.

基于流体力学原理，用UG造型出某型航空发动机8级涡轮转子叶片，用流场计算软件FLUENT构造电解加工中叶片的流场计算区域，经数值计算得到六维力的分布，并从理论上建立六维力与间隙之间的关系方程式，为后续试验研究提供了参考依据。

A structure of space-time diversity virtual double-route weighting interference mitigating is proposed, and the corresponding practical algorithm is derived in detail using block matrix inversion formula and matrix inversion theory for mitigating interference signals from both other cells and other users of local cell in the DS-CDMA up-link communication case. Performances of such algorithm are thoroughly analyzed through simulation and analytical results. The up-link and down-link channel characters and their relationship of DS-CDMA communication system are thoroughly analyzed, and the relationship of space-time diversity weighting matrix between time division duplexing and frequency division duplexing these two different transmission ways is derived.

本论文深入地比较了DS-CDMA通信系统的上传情形与下传情形的信道特性及其它们相互之间的关系；深入地分析并得到了时分双工和频分双工两种不同的传输模式下的上传情形与下传情形的空时分集权系数矩阵之间的数量关系，从而使得能够利用在基站端所拥有的上传情形的空时分集接收权系数矩阵信息以及其他信息在基站端直接形成空时分集发射权系数矩阵；推导了下传情形移动用户接收机端的最优组合接收策略及其算法；进一步地，对时分双工传输模式下的下传情形的通信系统性能和频分双工传输模式下的下传情形的通信系统性能进行了深入的比较仿真研究。

Based on the results from tests on the run up rhythm of college athletes in javelin throw, the paper showed that the major mistakes are poor stabilities and low utilization of speed in the run up ,by the means of biological mechanics.

本文以普通高校标枪运动员助跑节奏的测试结果，运用运动生物力学理论进行技术分析，认为助跑中的主要错误动作是稳定性差和速度利用率低。
