查询词典 moment method

Based upon Adomian decomposition method, we have studied Adomian double decomposition method in this paper. The initial term in Adomian decomposition method has been further decomposed, and modified inverse vector method is obtained.

在求解初边值问题Adomian分解法的基础上，研究了求二维偏微分方程边值问题的双重Adomian分解法，对Adomian分解法的初始项作了进一步分解，使逆算符分解法得到了改进。

Acetone-berberine quantitative method is recorded in J.P. X., but this method is complex, difficult and not accurate. In U.V. spectrophotometry determination, the absorbance of berberine will be disturbed by palmatine and other color constituents in these drug extracts. So we modified and used the T.L.C. scanning method and found that it is an accurate, prompt and useful method.

小蘗之定量法有日本药局方记载之Aoetone-Berberine重量法，，唯此法繁杂且误差大，如以分光光度法测定时，除小蘗成分外，尚会受到Palmatine等其他色素之影响，结果并不准确，故本次研完改用薄层层析斑点扫描法，发现其操作迅速、精确度亦高，极为适用。

Two improvements measurements pointed to the errors to calculating b values have been proposed:(1) to adopt the uniform absolute magnitude scale, seismic moment magnitude MW,(2) to discard the magnitude points for which the earthquakes absent and lose, and then to compute the b value using least square method to fit the data.

针对过去计算b值的误差，提出了两条改进措施：（1）采用统一的绝对震级标度-矩震级标度MW；（2）舍弃缺失地震次数的点，然后用最小二乘拟合求得b值，使b值计算较准确。

For the position and the attitude control system, a method of average aerodynamic forces and moment is designed.

重点研究了位置控制层和姿态控制层的控制系统设计。

Will hold the post of mottled bamboo from the doctor that invites major socially, website day visits a quantity to achieve hundreds IP, the server space discharge of hire is insufficient, visit rate is very slow, do not have method, be forced to buy oneself independent server, half an year went, visit quantity increases ceaselessly, increased a server again act against one's will, invite the relevant personnel such as net canal, technology, customer service at the same time, and at this moment the income that my website did not bring one article money for me, still threw several yuan instead.

从社会上聘请专业的医师来任斑竹，网站日访问量达到数百个IP，租用的服务器空间流量不够，访问速度非常慢，没办法，只好购买自己的独立服务器，半年过去了，访问量不断增加，不得已又增加了一台服务器，同时聘请网管、技术、客服等相关人员，而这时我的网站没有为我带来一文钱的收入，相反还投入了数万余元。

The retarded interaction between the charged particles with anomalous magnetic moment is derived by the correspondence method.

然后用对应的方法推导出具有反常磁矩的荷电粒子之间的推迟相互作用。
