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。

Plenty and purified satellite cells are obtained with these methods.IGF-1 could promote the proliferation and differentiation of mouse skeletal muscle satellite cell. Adequate single satellite cell could be obtained by frequent passaging method and the preparation are ready for for satellite cell transplanting.

结果：此方法可以获得足量、纯度较高的肌卫星细胞，适宜浓度的IGF对肌卫星细胞有较强的促增殖及促分化作用，频繁传代可以获取足量的单个肌卫星细胞，为肌卫星细胞移植做好了前期准备。

In the history of communication, even" communication model has its own factor of "affirmation" and ""negation". Mass communication is a ""negation" to personal communication while network communication turns to be a negation to mass communication, which means a "double negation.

在人类的传播史上，每一种传播方式都包含着"肯定"和"否定"的因素，大众传播是对人际传播的一种"否定"，而网络传播则是对大众传播的另一次"否定"，也就是"否定之否定"。

Although translator has turned from being a crystal ball by which the original culture can unrestrainedly penetrate to another crystal ball by which the target culture can freely traverse, the translator's personal embodiment, in the process of cognitive act, are still absent in translation studies. Translators are still subjects without body or simply disembodied subjects.
