Lineweaver-Burk 双倒数方程计算pH7.4 和 pH11.0 体系在温度为 20℃和 37℃条件下尼古丁和 BSA 的结合常数 k 分别为： k20℃=140.15 L·mol-1 ，k37℃=131.83 L·mol-1 （pH7.4）和 k20℃=141.76 L·mol-1，k20℃=27.79L·mol-1(pH11.0)，表明结合常数在 pH7.4 条件下受温度的影响要比 pH11.0 条件下小，推测是由于不同 pH 下尼古丁存在的不同形态所致。

Researching of Design Method and Capability of Tube Structure Possessed Double Helix-Cantilever Trusswork;2. The results show that the structure meets performance requirements of design,columns and shear-walls,steel members of cantilever and.

计算分析结果显示，结构在中震作用下所有柱及剪力墙未发生屈服、悬挑部分钢结构及其支撑柱保持弹性，实现了性能设计提出的性能目标，说明基于性能的抗震设计提高了结构的抗震性能，保证了&大震不倒&的设防目标。

The deletion of [A7-B7] disulfide bond in proinsulin resulted in a significant decrease of α-helix content of the molecule and a great increase in sensitivity to tryptic digestion.

结果表明，A7 B7二硫键缺失可导致胰岛素原α螺旋明显减少以及对胰蛋白酶的酶切敏感性显著增加，其对胰岛素原结构的影响主要导致了受体结合活性的大幅度降低。

The β-CA of B.napus was located in chloroplast stroma and had the conservative motif Cys-X(subscript n-His-X2-Cys peculiar to β type carbonic anhydrases. In the secondary structure,α-helix, random coil,β-sheet, and β-turn were 39.88%, 39.27%, 16.31%, and 4.53%, respectively. The three-dimensional structure was constructed by homology modeling. The 3-D alignment of β-CA from B.napus and a monomer of β-CA octamer from pea showed that the 3-D structure of β-CA from B.napus could match well with the monomer. The alignment results Implied that β-CA from B.napus was a monomer of the β-CA octamer from B.napus.

预测结果显示，甘蓝型油菜β破酸酐酶是定位于叶绿体基质的蛋白质，具有β类碳酸酐酶所特有的保守性基序Cys-χ-His-χ2-Cys；SOPMA预测二级结构显示α螺旋(39.88%)、随机卷曲(39.27%)、β折叠(16.31%)和β转角(4.53%)；用同源建模法构建了三维结构图；通过VAST矢量比对工具将甘蓝型油菜β碳酸酐酶与模板进行三维结构比对，显示甘蓝型油菜β碳酸酐酶与碗豆β碳酸酐酶同型八聚体中的一个单体很好的匹配，推测甘蓝型油菜β碳酸酐酶全酶也是同型八聚体。

In order to improve the inspection technologies of satellite interference, 5 kinds of technologies of satellite interference and integrated judgement-spectrum analysis, helix inspection, PID, S/N and signal vector were put forward. The automatic inspection system of interference of satellite TV has been built according to these inspected technologies and technology of network. The system adopts comparison of spectrum template, calibration of beaconing, mode identification, telemetering pick-up technology and improve the inspection technology of satellite interference. The alarm limits haw been defined through a lot of emulational tests, so that the system become feasible. The system has a good effect and makes up the blank of inspection technologies of interference in our country to some extent.

为了提高卫星干扰监测水平，提出了频谱监测、螺流监测、PID监测、S/N监测和信号矢量图监测等五种监测技术和干扰综合判断方法：根据这些技术手段和方法，并利用计算机网络技术，建立了卫星电视干扰信号自动监测系统；该系统利用网络化设计，采用频谱模板比对，卫星信标电平校准、信号模式识别、卫星遥测信号提取等技术，提高了卫星干扰监测的准确度和自动化程度；通过大最的仿真测试，设定告警门限，使系统的漏警率和误警率达到实用要求；该系统应用于干扰监测工作中，起到了很好的效果；在一定程度上弥补了国内通信干扰监测的空白。
