During the BPSE process, a high-speed special mode frame is sent, bit error rate is fed back to the sender, as well as signal to noise and BERs for each rate are obtained by looking up the empirical BER/SNR curve. During the SLRA process, the equation of goodput relative to BER and frame length is solved, to obtain the maximized goodput and its related BER and frame length.

SLRA先通过求解有效带宽、BER和包长度的解析方程，然后得到各种速率下的最优有效带宽、及其相应的包长度，从而在理论上优化有效带宽；由于SLRA计算过程非常复杂，我们提出了近似查表的方法来简化优化过程，使得其适用于便携式通信设备。

A new technology, Supercritical Fluid CO_2 Extraction, was also supplied to study the plant. The technological parameter was optimal. Total extract of SFE-CO_2 were 4.86 times of the essential oil extracted by SDE, main active extracted constituents were 1.36% high than SDE. The chemical constituents of SFE-CO_2 were also analyzed by GC-MS. 57 constituents were identified, 29 constituents of them were first discovered. 24 constituents were discovered in two extract. Fingerprint is a good technology to elevate the quality of herb medicine. The main active fraction can be extracted by SDE and SFE, Fingerprint was studied respective, chromatographic parameter was acquired. 22 peaks were assigned common peaks in the spectrum of essential oil, 17 peaks were assigned to common peaks in the spectrum of SFE extract.

采用现代共性关键技术超临界CO_2萃取技术，通过正交试验，优选了超临界CO_2提取牛至挥发油的工艺，并与传统的水蒸气蒸馏法进行了比较研究，结果显示：前者提取有效部位的收率为后者的4.87倍，主要有效成分的转移率是后者的1.36倍；采用GC-MS分析方法和NIST质谱库检索，对SFE和SDE所提化学成分进行比较，SFE分离鉴定了57种化合物，占提取物总含量的86.96％，其中29种化合物为首次从该植物中鉴定；后者分离鉴定了69个化合物，占提取物总量的98.28％，其中27种化合物为首次从该植物中鉴定；两种方法的提取物中共有成分25种，包括主要有效成分麝香草酚、香荆芥酚、对聚伞花素等。

Based on the concept of averaging electromagnetic field, the optical constants of Goodwin synthetic ash, Chinese Qitaihe coal ash and Russian ash Br-1 were calculated by Maxwell-Garnett and Bruggeman effective medium theory. Computational results show that, for the synthetic coal slag, the optical constants estimated by EMT consist with the experimental values, but for the coal-ash produced in combustion, the optical constants estimated by EMT using industrial analytical species deviate far from the experimental values.

从系统论的视角来看，不同的制度结构，其对经济增长的作用是不一样的；从制度融合与冲突的视角看，最有效率的制度安排是能够实现外在制度与内在制度的融合，反之，将会削弱外在制度规则的有效实施，降低制度效率，成为经济增长的绊脚石；从制度效率的视角进行考察，好的制度结构能通过制度效率的提高来促进经济增长，差的制度结构则降低制度效率；如果内在制度与外在制度融合得好，人为设计的制度质量就高，其能够有效实施并发挥出相应的制度效率，从而促进经济的有效增长，相反，就可能对经济增长产生负作用。
