通过引入经典优化中局部搜索能力较强的充分下降条件、Wolfe条件、Goldstein条件确定步长，而搜索方向采用共轭梯度方向进行局部搜索，由此得到一类高效的非精确的混合遗传算法。

A vehicle body structure includes a dash panel that partitions an engine chamber from the vehicle interior. An intake manifold for an engine is housed in the engine chamber, and an air box extends in a direction of the width of the vehicle and is located above the dash panel. A linking member is connectible to both the dash panel and the air box. At least a portion of the linking member overlaps a portion of the intake manifold in the direction of the width of the vehicle.

本发明提供了一种车辆的底盘结构，包括：驾驶室前壁板，其把车辆的发动机室与车辆内部分隔开；发动机进气岐管，其设置在所述发动机室内；空气箱，其沿着与车辆的宽度相对应的方向延伸，并且位于所述驾驶室前壁板的上方；以及联结构件，其连接到所述驾驶室前壁板和所述空气箱上，所述联结构件的至少一部分与所述进气岐管的至少一部分在沿着与车辆的宽度相对应的方向上重叠。

By the analysis of heat transfer between air and wall in vertical direction and the mechanism of air flow in large space building, this paper provides a theoretical model that the air temperature in vertical direction can be divided into three zones: temperature-constant air-conditioning zone, main convection zone and top heat stagnation zone.

通过对大空间建筑室内垂直方向上空气与壁面换热和流动机理分析，提出了空气温度在垂直方向上划分为等温空调区、对流主区域、顶部热滞留区域三个区域，建立了对流主区域、顶部热滞留区域求解空气温度的数学模型，推导得到了相应的分析解，提出了计算大空间建筑室内垂直温度分布简易模型。

Third, the discussion of the corresponding relationship of the real angles to the apparent real angles is performed, the asymptotic bias and MSE of real angles are given. Fourth, based on above conclusions, the analysis of two typical cases is made by numerical analysis and computer simulation: Case A when the impinging signals are divided into desired signals and interfering signals: it is shown that similar to Cyclic estimation of DOA, the smaller the separation between interfering direction and signal direction, in general, the smaller the estimation variance.

首先，研究了无穷快拍时信号数目有误的最大似然估计，引入了视在真实角度的概念；其次，导出了视在真实角度最大似然估计大样本时的分布以及渐近均方误差的解析表达式，而且还证明了：Stoica性能分析结果是现在的分析结果在信号数目准确时的特例；第三，讨论了真实角度与视在真实角度的关系，给出了真实角度的渐近偏和渐近均方误差；第四，依据前面的结果，利用数值分析和模拟实验的方法对两种典型情况做了分析： 1 在入射信号被分为干扰信号和所需信号情况下：结果表明：与CyclicDOA估计一样，干扰方向与所需信号方向靠的越近，所需信号估计的方差越小，越远离，方差越大。
