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

And therefore, whatever form the common-wealth is under, the ruling power ought to govern by declared and received laws, and not by extemporary dictates and undetermined resolutions: for then mankind will be in a far worse condition than in the state of nature, if they shall have armed one, or a few men with the joint power of a multitude, to force them to obey at pleasure the exorbitant and unlimited decrees of their sudden thoughts, or unrestrained, and till that moment unknown wills, without having any measures set down which may guide and justify their actions: for all the power the government has, being only for the good of the society, as it ought not to be arbitrary and at pleasure, so it ought to be exercised by established and promulgated laws; that both the people may know their duty, and be safe and secure within the limits of the law; and the rulers too kept within their bounds, and not be tempted, by the power they have in their hands, to employ it to such purposes, and by such measures, as they would not have known, and own not willingly.

所以，无论共同体处于什么形式之下，统治的权力都应当由公布并被接受的法律而不是由临时的命令和未确定的决议来支配：因为人类一旦将多数的联合权力武装一个或少数人，来迫使人们服从他们突发奇想的过度和无限制的法令，或者服从于此时尚没有确定的尺度来管理和裁判他们行为的无约束的意志，他们将跌入远比自然状态更糟的境遇之中：因为政府所拥有的所有权力，既然仅仅只是为了社会的利益，就不应当是肆意和凭一时高兴的，它应当依建立和公布的法律来行使；不仅人们知道自己的责任，知道在法律的约束之中安全能够得到保证；而且统治者也被限制在他们的边界之内，而不会被他们手中的权力所诱惑，从而雇用这种权力去为人们并不知道和并不情愿的目的服务，并作为这样的手段。

And therefore, whatever form the common-wealth is under, the ruling power ought to govern by declared and received laws, and not by extemporary dictates and undetermined resolutions: for then mankind will be in a far worse condition than in the state of nature, if they shall have armed one, or a few men with the joint power of a multitude, to force them to obey at pleasure the exorbitant and unlimited decrees of their sudden thoughts, or unrestrained, and till that moment unknown wills, without having any measures set down which may guide and justify their actions: for all the power the government has, being only for the good of the society, as it ought not to be arbitrary and at pleasure, so it ought to be exercised by established and promulgated laws; that both the people may know their duty, and be safe and secure within the limits of the law; and the rulers too kept within their bounds, and not be tempted, by the power they have in their hands, to employ it to such purposes, and by such measures, as they would not have known, and own not willingly.

因此，国家无论采取什么形式，其统治权力都应依据业已公布且被接受的法律而不是临时的指令或犹豫不定的决义来进行治理；因为，假若人类用群众的联合的力量来武装一个或几个人，任其随心所欲地迫使人们服从其一时心血来潮所做出的种种过分的、无限制的命令或是毫无节制的、此时尚不得而知的意志，而同时却没有任何固定的措施来引导他们的行为或为之辩护，那么，人类将处于比自然状态远为糟糕的境地；既然政府所拥有的一切权力均旨在为社会谋福利，因而不应专断独行、随心所欲，因此，它必须依据明确规定且公诸于众的法律来行使；这样，不仅人民可以了解他们的义务，在法律范围内得到安全和保障；而且，统治者也可以受到法律的约束，而不致被手中掌握的权力所诱惑，进而利用它达到特定的目的，且采用特定的手段，而这样的目的和手段是他们本来可能不会知道、也不愿承认的。
