通信管道应注意的几个问题
目前，通信管道一般都是埋于地下，那地下环境不排除会有些土壤潮湿或渗水等环境那就好考虑管道防腐性能方面；有时需要穿过交通主干线那就要考虑管道的抗击性、环钢性等方面，不然后期地面有下陷或塌陷等问题；
宝通BWFRP管道精选高性能纤维复合材料及其制品作为增强材料，以合成树脂作为基体材料的一种复合材料，通过专业设备，实现全自动话应用编织编绕拉挤工艺，由内编织层，纵向层、环向层、外编织层等4层结构组成。使BWFRP管道具有强度高、抗冲击力强、任性好、耐腐蚀、耐高低温、绝缘阻燃、使用寿命长、内外表光滑（穿缆、线容易等）、产品重量轻、无毒绿色环高等等优势特点。
宝通BWFRP管道以优质的原材料及生产工艺，从物理上规避传统材料管道工程施工难、易腐蚀易损坏、耐压耐温性差等多种缺陷。可适应苛刻的恶劣环境（包括深海、露天及露天高低温等）等。

够了吗?
CreateFile和fopen的关系，我的理解对吗？
我感觉你的理解是正确的，就WIN32平台下，我们做一个实验 #include "stdafx.h" int main(int argc, char* argv[]) { fopen("c:/123.txt","r"); printf("Hello World!\n"); return 0; } 上面这段代码 编译之后 形成一个exe，我们用OD载入之后 在CreateFile下一个断点 然后 在OD中运行程序，程序最终会中断在CreateFile处 fopen是标准C的东西，不同的平台对fopen实现的手段不一样，但最终表现出来的一样的 只要对外表现一样，内部各种实现都可以的。
