使不方便

Theoretical Part: Through theoretical analysis of chemothermodynamics, combustion and engineering thermodynamics, factors that affect explosion limit were determined, which include temperature, pressure, spark ignition energy, electrode shape, direction of flame propagation and size of explosion vessel.

理论部分：根据化学热力学、燃烧学和工程热力学的基础理论，从本质上定性地分析了爆炸极限的影响因素，包括温度、压力、爆炸容器的大小、点火能量大小、以及火焰传播方向等，得出了这些影响因素对爆炸极限的影响规律，以确保实验有完整的理论基础指导；在此基础上本文提出了一种新的推算在常温常压下可燃性纯质和混合工质制冷剂爆炸极限浓度的理论方法，该方法由可燃性气体的化学组成来推算上下限浓度，不需要其它条件；对混合工质制冷剂，只要再知道混合配比，即可以推算出爆炸极限，使预测爆炸极限的工作更简单、方便。

硬件方便的儿童，必须设计和建造，使其不箍缩，瘀伤，破碎， lacerate ，突破，或amputate任何的一个组成部分child'的身体在正常使用或可合理预见的损害或虐待，向垛。

This will make it more user friendly especially for those old folks that can't live without web surfing.

这将使它更方便用户特别是对那些老人们，不能生活在网上冲浪。

Passive power filters is adopt widely because it is simple configuration, convenient maintenance, low cost and etc. Otherwise, passive power filters is easy affect by change of system parameters, can' t remove sequential harmonics, and easy arose series and parallel resonance with system.

无源电力滤波器由于其结构简单，维护方便，造价低廉等优点仍然成为目前普遍采用的一种滤波手段，但是无源电力滤波器受到系统结构变化影响较大，不能消除连续谐波，且容易和系统阻抗发生相互作用，引起串联、并联谐振，严重时甚至使系统崩溃。

Lightweight and shatterproof, the bottles are safe and easy to handle, while their squeezable construction makes pouring both convenient and fun.

重量轻，不碎，瓶子是安全的，易于处理，而他们有弹性的建设，使浇注既方便和乐趣。

TW-600 Outside pumping vacuum packer: using air pressure style sealing, and it is clean and reliable; adopting the Japanese and Korea technology and equipment, is provided with dual functions of vacuum and charge; the whole machine circuit is from Korea and is programmable control, and is stable; sponge shape silica gel bar to ensure a fine airproof after pumping out the air; using the variable stroke air cylinder to make sure the sealing is neat and tidy; it is a perfect safe packaging after the product charge; stainless platform, and can adjust the height freely in terms of the size of the packaging goods; and also can change the work place easily for its installing truckle; simple style storage case to store the vacuum packaging bag or spare part in common use; Light touch style padding switch can be operated conveniently.
