When free riding exists between channels, the competition between Internet direct channel and drop-shipping channel is studied. We find that providing Internet direct channel does not necessarily lead to lower expected payoff for Internet retailer, it depends on the effect of drop-shipping channel free ride on Internet direct channel. When the effect is good, the retailer can achieve higher payoff.

5在渠道之间存在免费搭乘现象的情况下，建立了drop-shipping渠道和网络直销渠道之间的竞争模型，指出供应商提供网络直销渠道后，并不一定就导致零售商利润的下降，这依赖于drop-shipping渠道免费搭乘网络直销渠道的效果，当效果高于一定水平时，零售商的利润增加。

On the basis of the kinetic equation of substrate reaction in the presence of urea or guanidine hydrochloride, all microscopic kinetic constants for the free enzyme and enzyme-substrate binary and ternary complexes have been determined. The results of the present studies indicate that:①In the presence of urea or guanidine hydrochloride, enzyme-substrate complexes lose their activity less rapidly than the free enzyme. Therefore, both substrates, NADPH and 7, 8-dihydrofolate, protect dihydrofolate reductase against inactivation.②The denaturation of dihydrofolate reductase by urea follows single-phase kinetics, and changes in enzyme activity and tertiary structure proceed simultaneously in the unfolding process, so it may be an"all or none"process.③The GdnHCl-induced unfolding of the dihydrofolate shows a biphasic transition, while the change in the enzyme activity is a single exponential process. The rate constant of inactivation is consistent with that of the fast conformational change. Therefore, the kinetic intermediate of protein unfolding should be a partially folded and inactive form.

我们根据在脲或盐酸胍存在下的底物反应动力学方程求得游离酶和酶底物二元、三元复合物的微观动力学常数，结果表明：①酶-底物二元、三元复合物的失活速度明显慢于游离酶，说明两个底物二氢叶酸和NADPH对酶的失活都具有一定程度的保护作用；②在脲作用下，酶的失活和构象变化均为单指数项过程，而且酶的活力丧失和三级结构变化是同时发生的，说明二氢叶酸还原酶的脲变性可能是一个"全或无"的两态过程；③在盐酸胍作用下，酶的构象变化为两相过程，而失活则是单指数项过程，酶分子构象变化的快相速度常数与失活速度常数基本一致，因此我们认为二氢叶酸还原酶的盐酸胍变性过程中存在一个没有活力、但仍具备一定空间结构的变性中间体。

Free at last free to lie powerless in the dirt, to be blown helplessly along the ground, and to lodge lifeless against the first obstruction.

终于自由使他自由到无力地躺在尘土中，无助的让风沿着地面将其吹走，碰到第一个障碍物便毫无生命的滞留在那里了。

Free at last, free to lie powerless in the dirt, to be blown helplessly along the ground, and to lodge lifeless against the first obstruction.

自由来自于对无情的微风的抵抗的幸运，它总是在最后获得自由，自由得面对一切，在地面之上是没有帮助，并且对抗着第一次的障碍。

Free at last free to lie powerless in the dirt, to be blown helplessly along the ground, and to lodge lifelessagainst the first obstruction.

终于自由使它自由到无力地躺在尘土中，无助地任风沿着地面将其吹走，碰到第一个障碍物便毫无生命地滞留在那里了。

Free at last free to lie powerless in the dirt, to be blown helplessly along the ground, to lodge lifeless against the first obstruction.

终于自由使它自由到无力地躺在尘土中，无助地任风沿着地面将其吹走，碰到第一个障碍物便毫无生命地滞留在那里了。

Free a last , free to lie powerless in the dirt, to be blown helplessly along the ground, and to lodge lifeless against the first obstruction.

终于自由，自由无力地躺在尘土中，无助地任风吹得满地跑，碰到第一个障碍无便毫无生命地滞留在那里了。

"Free at last" free to lie powerless in the dirt, to be blown helplessly along the ground, and to lodge lifeless against the first obstruction.

它"终于自由了"，自由到无力地躺在泥土上，沿着地面无力地被风吹走，一旦遇到障碍便死气沉沉地滞留在那里了。

The basic concept of FOP can be summarized as to further optimize effective prescription according to the standard of curative effects and with the aid of modern science and technology and theories of traditional Chinese medicine.
