The bamboo is exempted from pesticide contamination because it can produce negative ion itself and has the insect-preventive and anti-microbial functions, which can protect it from diseases and insect damage. Moreover, the bamboo fiber is produced by high technology without the addition of chemical additive, and it is characterized by various properties such as natural antibiosis, bacteriostasis, anti acarid, deodorization, anti-ultraviolet, and excellent ventilation, instant water absorptivity, strong wearing resistance, outstanding dyeing property and beautiful appearance, etc.

The results of simulations have shown that the molecular deposition film is similar to the self-assembled monolayer during scan process.

以量子化学计算结果作为初始条件，进行了分子沉积膜在金探针作用下的扫描过程和纳米压痕过程的模拟。

Petrochemicals are broken down by cracking, during the refinement process, and are thus sensitive to heat process.

这是因为石油化学物质在提炼的过程中通过分馏而分解了，因此它对加热过程很敏感。

The planetesimals accretion s of the Earth obviously have two stages, including initial accretion and late accretion .

地球的星子吸积过程具有明显的两阶段性，即原地球吸积阶段和晚期吸积阶段，而后期的吸积过程对上地幔及地壳的化学成分不均一性的影响尤为显著。

FRs can strongly suppress the elimination of HCl, raise the on-set temperature of decomposition of PVC, promote the crosslinking during decomposition, reduce the total output of aromatic compounds, increase the gel of condensed phase and char residue, the char residue is loosened. The configuration of FRs has no changed.

这类阻燃抑烟剂能抑制PVC热分解脱HCl反应，提高HCl释放的起始温度，在热分解过程中促进分子间形成交联键，使裂解气相产物中芳烃化合物含量减少，凝聚相凝胶含量增大，残炭量提高，残炭物结构呈松散状态，阻燃抑烟剂在热分解过程中化学结构保持不变。

In this paper, the control factors of anaerobic digestion are discussed based on the summarization of present research literatures. The mechanism of the effect of pH and Eh on anaerobic digestion is analyzed with microbiology and biochemistry theory. The equation describing the effect of pH variation on Gibbs free energy variationΔGis derived using Nernst equation, and the specific control conditions in engineering are summed up according to the present research achievements.
