较低的

The results were as follows.(1) In the backward handspring, the trajectory of CM and horizontal velocity of CM in junior-high and college gymnasts were lower and higher than those of senior-high gymnast, so the vertical velocity is better when they perform tucked backward somersault. College gymnast has higher vertical velocity than junior-high and senior-high gymnasts in take-off moment of backward handspring phase.(2) Senior-high and college gymnasts have more elbow and shoulder angle in take-off moment of backward handspring and tucked backward somersault phase. Therefore, angle of both arm is bigger for performing in hand push away phase in the backward handspring, and increased the reaction force with body in the tucked backward handspring.(3) College gymnast has large knee flexions in hand support and push away moment in the backward handspring, it would increase rotation radius and better moments of inertia in the backward handspring.

结果显示：在后手翻阶段中，较低的重心轨迹和较高的水平速，有於后续空翻的垂直速；大专选手在后手翻阶段起跳瞬间有较高的垂直速；高中及大专选手在后手翻起跳脚地瞬间和团身后空翻起跳脚地瞬间时，肘、肩关节角皆大於国中选手，使其在后手翻起跳地瞬间时，双臂的伸展於后手翻的手推地面的动作，而团身后空翻起跳脚地时，双臂向上摆於身体向上伸展方向的掌握，并使重心有一定的腾空高；大专选手在后手翻阶段的手著地瞬间和手地瞬间的膝关节角较大於高中和国中选手，使其可增加身体的旋转半径，并能获得较佳的下摆动能，而膝关节角小则形成屈膝的动作，导致重心水平速低，减少下摆动能和影响整体动作的节奏和韵。

First low order approximation of generating function and approximate optimal trajectory were obtained. Then using low order approximation of generating function of Hamilton "relative motion" to the approximate optimal trajectory, improvement of the approximate optimal trajectory was iteratively made. In this way, high order approximation accuracy can be obtained by only using low order approximation, which is much cost effective in computing.

首先以较低的计算代价，获得最优控制Hamilton系统生成函数的低阶近似，得到一条近似的最优轨线，然后将最优控制Hamilton系统相对于近似最优轨线求"相对运动"，该"相对运动"仍具有Hamilton性质，利用这一"相对运动"的生成函数低阶近似，可以对近似最优轨线进行迭代修正，从而以计算代价较小的低阶近似逼近计算代价高得多的高阶近似的精度。

Bounding in eastern Fenghuang, similar to Te, the crustal thickness can also be divided into two sections: northwest high value section and southeast low value section, and there is roughly a positive correlation between crustal thickness and effective elastic thickness of the lithosphere, namely higher crustal thickness value corresponding to relatively higher Te value and lowerer crustal thickness value to relatively lower Te value, which reflects that the lithospheric strength is directly proportional to the crustal thickness in regional tectonic background.

以凤凰东为界，与Te值类似，地壳厚度也可以宏观分为南东低值段与北西高值段，地壳厚度大体上与Te值呈正相关关系，相应较大地壳厚度对应较高的Te值，较小地壳厚度对应较低的Te值，说明在大的区域构造背景下，岩石圈强度与地壳厚度成正比。

The patients with lower serum glycine or D-serine levels, more severe negative symptoms and cognitive deficits, abnormal expression in mRNA or protein levels of certain genes (e.g., lower expressions of SHMT2, PSAT1 and serine racemase; higher expressions of AMT and ASCT1) may be more likely to respond to sarcosine.

此外，用药前具有较低的血清glycine或D-serine浓度、较明显的负性症状或认知功能缺损、以及特定基因於mRNA或蛋白质层次表现异常(如：SHMT2、PSAT1及serine racemase表现较低，而AMT及ASCT1表现较高)的患者，可能对sarcosine有较佳的治疗反应。

The results show that dynamic leaching of heavy metals increases with decreasing pH values on the whole, but the relativity is not significant. The leaching concentration is negatively correlated with time. The calculation results show that the elements with the largest cumulative leaching amount are Fe, Mn, Zn and As, and those with the smallest amount are Pb, Sn, Hg and Cd. The elements with the highest stage lixiviating rate are Ni, Co, Cr, Mn, Cd and Cu, and that with the lowest rate is Fe. The elements with the highest values of cumulative lixiviating rate and cumulative lixiviating intensity are Cr, Mn, Co, Ni and Zn, and that with the lowest ones is Fe.

结果表明，重金属元素的动态浸出整体随pH值下降而升高，但相关性不明显，浸出浓度与时间整体上呈负相关关系；浸出总量效果较好的元素为Fe、Mn、Zn、As，较差的为Pb、Sn、Hg、Cd，其他元素中等；阶段浸出率较高的元素有Ni、Co、Cr、Mn、Cd、Cu，较低的元素有Fe，Sn、Zn介于中间水平；累积浸出率和累积浸出强度较高的元素有Cr、Mn、Co、Ni、Zn，较低的元素为Fe，Cu、Cd、Sn居于中间水平。

This article has studied HG70 steel and HS-70 welding wires weldings,the welded joint,welding quality,and the welding operational performance,in restricts under the welding condition,Uses HS-70 welding wires,Experiments the steel plate the weld joint stretch,degree of hardness and the resilience test result indicated that,HG70 steel and HS-70 welding wires weld joints have the low crack sensitivity,The welding quality is good,Its weld joint has the fine mechanics performance,thus explained they had the fine welding match.

0前言非调质钢具有优良的使用性能和较低的生产成本，受到普遍重视。HG70钢是武钢开发的工程结构用钢，具有强度高、低温韧性好的特点。传统高强度钢一般碳当量较高，焊接性能较差。通过加入微量合金元素、采取新的控轧和调质工艺，使得HG70钢在提高强度的同时，亦保持了较高的韧性和较低的碳当量，因而从理论上讲HG70应具有较好的焊接性能，但HG70钢与HS-70焊丝的匹配情况，还有待于分析验证。
