If it can be shown, firstly, that exogamous tribes exist, or have existed ; and secondly, that in rude times the relations of separate tribes are uniformly, or almost uniformly, hostile, we have found a set of circumstances in which men could get wives only by capturing them — a social condition in which capture would be the necessary preliminary to marriage . And

如果能够被证明，首先，异族结婚的部落存在，或曾经存在；第二，在野蛮时代分离的部落的关系是一律，或几乎一律敌对的，我们便发现了男人只能靠俘获她们得到妻子的一种环境——劫掠对结婚将是必要的预备的一种社会条件。

And while this state of enmity lasted, exogamous tribes never could get wives except by theft or force.If it can be shown, firstly, that exogamous tribes exist, or have existed ; and secondly, that in rude times the relations of separate tribes are uniformly, or almost uniformly, hostile, we have found a set of circumstances in which men could get wives only by capturing them — a social condition in which capture would be the necessary preliminary to marriage .

那么在一个合理数目的经良好鉴别的案例中，如果这些条件——异族结婚为部落法律，并且敌对是分离的各部落相互对待的主流关系——被证明如可预期的，伴随着一种猎妻制度，而存在或曾经存在，我们将有理由推断——没有出现不符合这种解释的现象——在劫掠体制流行的地方，或者劫略形式作为一种结婚礼仪被尊奉的地方，这些共同的条件存在于每一个案例之中。

In 1966, Ross solved the equation of symmetrical free vibration and got six matching solution, but he believed that it is impossible to find a solution which is useful in everywhere. In 1979, Goldenveizer printed a monography in which the uniformly valid representations of curved solution were published, but the representations of membrane solution were still not found. In 1988, Ruo-jing Zhang published the uniformly valid representation of six solutions for symmetrical free vibration and eight solutions for dissymmetrical free vibration for the first time.

但却碰到巨大困难。1966年，Ross给出了轴对称振动的6个匹配解，但却认为不可能求出全域一致有效解。1979年，Gol&denveizer等出版专著，给出了弯曲解的全域一致有效表达式，但仍然没有得到6个解中奇异薄膜解的全域一致有效表达式。1988年，张若京在其博士论文中第一次给出了轴对称6个解和非轴对称8个解的全部&全域一致有效表达式。

In the buckling question under nonconservation force,a simply example( the dynamic stability question under the uniformly follower forces with small deformation % linear elastic, straight normal.) is considered.The variational equation of braid composite cylindrical shells subjectd to uniformly follower forces is deduced based on the variation principle of quasinatural frequency of elastic nonconservative system self-excited vibration.The calculated formulas of the flutter load and quasinatural frequency of shells are obtained. The program for calculating the flutter load is developed.The numerical example is given and some useful conclusions are obtained.
