Holding the bow is like a teeterboard supported by thumb as the pivot and the cooperated forcing of forefinger and little finger produces a moment M. The "P-x-M Line Method" shows when playing a down bow, M increases with x and gradually changes its direction and this process is determined by P, the gravity and barycenter of bow. The "P-x-F Plane Method" shows that the most force-saving bowing path should locate in the lower part of this plane. The analyses of "Helmholtz Motion" and "Schelleng Diagram" indicate P and its range is in direct ratio with volume, velocity of bow, the approaching degree of the bow to the bridge and has some relationship with the quality of string and bow.

国内近期出现了用物理模型来研究小提琴运弓问题的尝试本文第一部分首先指出握弓类似于一个以***(F3)为支点的跷跷板，主要以食指(F1)和小指(F2)的施力配合，产生握弓力矩M；随后用"P-x-M直线法"证实：演奏下弓是M随的***而逐渐增大并转换方向的***，此***取决于P、弓的重力和重心；并首创"P-x-F平面法"，在x，F1，F2空间中证实：省力的运弓路径应在该平面中处于较低的位置第二部分通过分析"赫尔姆霍茨运动"和"Schelleng图表"指出：P及其变化范围和音量、弓速、弓与琴码的接近程度成正比，并与琴弦和弓自身的性质有关

As to the procedure of obtaining evidence, the writer points out some procedures which are illegal and will result in the invalid of E-mail; as to the authenticity, several methods to identify were concluded and their advantages and disadvantages are also listed. In addition, the writer points out that the laws in force on the authenticity of E-mail were very macroscopic and vague. And there are not concrete laws in effect to identify the authenticity of E-mail without electronic signature and encryption. So the writer explains his views that each links of E-mail's lifecycle should be deeply analyzed and checked to exclude the possibilities of unauthenticity of E-mail.

就取证程序方面，该部分则指出了哪些取证程序是违反法律并可能会导致电子邮件无效；就电子邮件真实性的问题，本文主要从现有立法归纳出几种认定电子邮件真实性的具体方式，并阐述了这些方式的利弊，同时笔者还在该部分指出，现行法律对于电子邮件真实性问题的认识，仍仅停留在宏观层面，显得过于宽泛，尤其是针对未经签署电子签名和加密的电子邮件真实性的认定问题，现行法律没有进行具体规范。

The third part points out that the course construction exists two problems: the idea of the course construction lack definition, causing the course construct work at sea, what is more serious that the theoretical support of the higher education course construction is vapidity, the course construction theories point out that the power of the high school construction aspect is feeble, the target is dispersed, the result is odds and ends, lack the research to higher education course characteristic, etc.

第三部分指出课程建设中存在着两个问题，课程建设的理念不清晰，导致课程建设工作的迷茫，特别是高等教育课程建设的理论支撑乏力，指出了高校课程理论建设方面力量弱，目标散，成果零碎，缺乏对高教课程特征的研究等问题。

Furthermore, the paper has put forwards the verifiability of the reform of state-owned enterprises, points out the standard of verifiability is whether the efficiency of enterprises can be raised, competition ability can be strengthened, total amount can be increased and structure can be optimized.
