The system parameters are determined by optimizing an output-error cost function. To deal with the non-uniqueness of the fully parameterized state-space system, a projected gradient search algorithm is presented by restricting the update of the parameters to the tangent space to the manifold of observationally equivalent state-space systems. The sufficient condition to employ L-M algorithm for optimizing parameters is also introduced. The proposed hierarchical optimization identificationmethod includes two steps: First, the parameter search direction is determined by the proposed adaptive L-M projected gradient approach; Second, the optimum step size is computed according to a line search method.

通过极小化输出误差目标函数获得了系统参数估计；提出了正交梯度搜索方法用于解决系统参数的非唯一性问题，正交梯度搜索的本质是在输入-输出等价类相切平面的正交垂空间更新系统参数；给出了用 L-M 算法进行参数优化的充分条件；提出的系统参数递阶优化辨识方法包括两步：首先用给出的自适应 L-M 算子正交梯度方法确定参数优化方向；其次由一维搜索方法计算最佳步长。

The whole goddamned medievalism of the place was infernally ticklish and restive, rocking back and forth with low moans, jumping out at you from the eaves, hanging like broken necked criminals from the gargoyles.

这地方见鬼的中世纪遗风极难对付、极顽强，它低声呻吟着来回摇晃，从屋檐下跳出来向你扑来，像被割断脖子的罪犯那样从滴水嘴上垂下来。

It's not the stunning neckline or the way clothes hang so lustfully off the bosom, nor their sculpted stomachs or their itty bitty waist.

不是足以使人犯晕的领口，不是衣服以极为淫荡的方式垂下直到离开胸部，更不是她们完美塑型的小腹部或者她们极细小的腰部。

Principle of its structure as shown, via a conveyor belt drive roller and tail roller with the formation of The Promise Ring, up and down a conveyor belt supported by rollers to limit the deflection of the vertical conveyor belt, the tensioning device to provide the required normal operation of a conveyor belt tension.

其结构原理如图所示，输送带绕经传动滚筒和尾部滚筒形成无极环形带，上下输送带由托辊支撑以限制输送带的挠曲垂度，拉紧装置为输送带正常运行提供所需的张力。

Both upper and lower epidermis cells are polygonal or irregular in shape in all species studied. The patterns of anticlinal walls are straight, arched or sinuous, and the raphal cuticular striastriae are occasionally observed on periclinal walls. Stomatal apparatus and secretory cells are found on the upper epidermis of several species and on the lower epidermis of all Species. The slomata apparatus mainly belong to the paracytic type and latercylic type; rarely anomocytic type occurs along with the paracytic one.

结果表明：这些植物叶片的上、下表皮细胞呈多边形或不规则形，垂周壁式样为平直、弓形或波浪状，平周壁偶有脊状条纹；少数种类上表皮还有气孔器或分泌细胞，所有种类下表皮具气孔器和分泌细胞；气孔器类型以平列型和侧列型居多，偶尔有无规则型；气孔极区呈稍角质加厚或棒状加厚，稀T形加厚。
