On average, the SSC in winter is 2 times than that in summer; and the SSC in spring tide is 2.96 times than that in neap tide.(2) The correlation coefficient of the daily tidal range and SSC at a tide circle is 0.86, and it goes up to 0.96 and 0.93 with one day and two days lag of SSC. This reflects that there has a hysteresis of one or two days of SSC to the tidal range.

The conclusion is that the path of Nanjie's institutional change is the outcome of the coevolution, say, competition, constraints, enforcement and transformation between the state and market; the coevolution have three dimensions: benefit, legitimacy and ideology; the path and outcome of institutional change in the process of coevolution are shaped by both the dual process of modernization and marketization in China's social transformation and the path dependence and cultural lag in China's incremental reform strategy: on the one hand, as historical conditions, the proceeding and logic of China's modernization constraint the state and market's institutional choices; on the other hand, under the interplay between the path dependence and cultural lag, the interaction between the state and market can produce various complex combinations, therefore various institutional landscape, even "institutional paradox".

本文认为，高度政治化、高度集体化的南街村体制是国家与市场互动演化，即国家与市场之间相互竞争、制约、强化和改变的结果；国家与市场之间的互动演化有利益、合法性和意识形态等三个维度，而互动演化所造成的制度变迁轨迹和结果则同时受中国社会转型中的现代化进程和市场化进程，以及渐进式改革中的路径依赖和文化堕距的影响：一方面，现代化进程作为一种共同的历史条件制约着国家和市场各自在互动过程中的制度选择；另一方面，在路径依赖和文化堕距的交互作用下，国家与市场之间的互动会形成多种复杂的、犬牙交错的组合，从而塑造出千姿百态的制度景象甚至"悖论"。

This invention relates to one MIMO-OFDM system simultaneous method, which comprises the following steps: a, processing relative computation by received local sequence and local ones to get relative peak and its side; b, processing filter on peak value and sides through one degree impact without limit; c, in the non integral digital sampling, the said peak value and its side are ordered to keep their position as time lag information; d, in the integral code sampling, it orders the peak value and its side and removes the sides and keeps relative peak position as time lag position to realize the simultaneous process.

In conclusion, the lag phase of Streptococcus thermophilus was shorten in the eutrophy culture medium, and the time achieving the culminated point of logarithmic phase was shorted also, at the same time, the stationary phase lengthened. After secondary culture, Streptococcus thermophilus reached directly the log phase hardly through the lag phase, and then quickly reached the decline phase. There were more relations of the metabolic regalities of the three kinds of nutritive substances with the super-concentrated incubation process of Streptococcus thermophilus: the more the number of the bacteria, the quicker the metaboling, while the fewer, the slower the metabolism. Moreover, there apparently existed morphologic changes in this course, and there maybe existed the apoptosis, which correlated with bacteria propagation and acid producing. With the culture time postponed, the nutritive substances in the culture medium lacked also, and the morphologic change and apoptosis appeared more obviously.

结果表明，嗜热链球菌在营养丰富的培养基中的生长延滞期缩短，到达对数生长顶点的时间变短，稳定期的时间延长，当经过二次培养后，嗜热链球菌几乎不经过延滞期直接到达对数期，平稳期持续的时间较短，很快到达衰亡期；嗜热链球菌在超浓缩培养过程中三大营养物质的代谢规律也同它的培养过程有很大的关系，菌数多，其代谢旺盛，菌数降低其代谢速度减慢；嗜热链球菌在超浓缩培养过程中存在着明显的菌体形态变化，并可能存在着细胞凋亡，与菌体增殖和产酸规律密切相关，随着培养时间延长，培养基中营养物质变得贫乏，菌体形态变化和细胞凋亡的情况愈加明显。
