反曲线

The empirical curve has since always been the enterprise uses for to analyze the market competition tendency and the development correspondence strategy method, and the experience which accumulates by the enterprise elders takes the main competition weapon, however the science and technology flies suddenly the progress, the enterprise defends stubbornly already has the experience instead to become the barrier which the enterprise develops, therefore in under the dispatch change environment, the experience and the extant channel foundation structure instead becomes the barrier which most difficult to overcome, the success enterprise must establish to the strategy direction sense of smell and continues the vicissitude management system to be able to survive.

一直以来经验曲线是企业用来分析市场竞争趋势及发展对应策略的方法，并以企业长年积累的经验作为主要竞争武器，然而科技的突飞进步，企业固守既有经验反而成为企业发展的障碍，因此在调度变化的环境下，经验及现存通道基础结构反变为最难克服的障碍，成功的企业要建立对策略方向的嗅觉和持续变迁管理体系才能生存。

The article mainly analyzes how innovation affects the social welfare and makes some conclusions as follows: firstly, influences on the price and output of products of innovation by oneself are uncertain, but innovation can enhance social welfare when it reduces the product price or raises the price but diminishes the elasticity of inverse demand curve.

本文重点分析了企业创新对社会福利的影响，得出的主要结论如下：（1）独立创新对产品价格和产量的影响是不确定的，但当创新使产品价格下降或者创新使产品价格上升且使反需求曲线的弹性变小时，独立创新能够增加社会福利；（2）联合创新能够降低每个企业的成本，增加企业的研发开支、产量和利润，因而联合创新有利于社会福利；（3）在考虑了创新的溢出效应后，存在一个外溢比率的帕累托最优区间，但我们必须在创新激励与社会福利之间做出权衡。

RESULTS The trend of dynamic frequency response of piezoelectric coagulation corresponded with the inverse S curve F =（f0-△f）＋△f/1＋e^（t-t0）/dtderived from theory according to the change regularity of the viscosity and density in the reaction system.

结果 根据反应体系黏度密度变化规律，理论推导出体外凝血反应过程，中压电频率动态响应规律符合F=（f0-△f）＋△f/1＋e^（t-t0）/dt等‰模型；根据该模型建立了新的反S拟合曲线法；与既有的最大拟合曲率法相比，前者检测速度更快（P〈0.01），重复性更好（P〈0.01）。

By carrying out ~1H spin-diffusion experiments,the domain sizes of DNA in the complexes were determined.The domain size of DNA is found to decrease greatly when the N/P ratio changes from 0.5 to 3 and changes only slightly with further increase of the N/P ratio.After making a thorough analysis and discussion on drug control release and gene delivery systems with general NMR techniques,we presents a method of 1D PFG NMR technique to realize quick observation on the Mw change of polymer during its degradation process.Moreover,according to the inverse Laplace transformation theory and based on a function of diffusivity distribution of polymer in solution,2D PFG NMR technique is developed to measure the Mw distribution of polymer.Combined with Monte Carlo simulation,the degradation mechanism can be figured out.

At the same time, under the condition of small strain, firstly, the secant shear modulus was always larger than the tangent shear modulus. Secondly, when the logarithmic coordinates were applied to describe shear strain, the decrease of shear modulus with shear strain could be expressed by reversed S shape curve with two inflexion points, and through analyzing and validating, the deduced equation could perfectly reflect this characteristic. Finally, different stress paths and strain areas would lead to different attenuation trends.

而且，在小应变范围内，割线剪切模量总是大于切线剪切模量；当剪切应变采用对数坐标表示时，剪切模量随着剪切应变的增加而衰减，且衰减的规律都可以表示为带有两个拐点的反S型曲线，经分析验证本文所得公式3可以对此特性进行很好地反映；但应力路径、应变范围不同其衰减幅度不同。
