The variation of total gas pressure also influences the deposition rate, optical band gap and extinctive coefficient of amorphous silicon film.

傅立叶红外光谱分析了在KBr衬底上沉积的非晶硅薄膜的官能团信息，说明衬底温度和气体压强变化影响了薄膜中的氢含量改变。

And the scientific research showed that they are medicable to insomnia, anxiety and other diseases that found in modern people. 4 The regression models of biomass were used to calculate the total cumulative biomass. Average biomass of six samples was 62.88 t·hm-2 after cutting 3 years, which was higher than that of tropical secondary forests with 5 years succession. It can be concluded that traditional fuel woods had played an important role in conservation of tropical forest in the area. Caloric values were not different in major fuel species (Coefficient of variation was only 1.1%). The similar result was found in stems of C. siamea after growing different years. The main reason of C. siamea cultivation was that it had the character of hardwood, easy collecting, little ash, and so on.

铁刀木的各个部位都作药用，资源量大的树叶和心材使用最多，并且现有的研究成果表明它们具有多种活性成分，针对现代人常患的失眠、焦虑等疾病具有较好疗效。4）通过收获法拟合的生物量回归模型对推测西双版纳地区铁刀木林薪柴蓄积量有较高的参考价值，砍伐3年后的六个样方中铁刀木的平均生物量为62.878 t.hm-2，高于5年林龄的热带次生林（16.35t·hm-2），对西双版纳热带雨林的保护有着重要意义。5）几个村寨最主要的薪材树种热值研究结果变异系数仅为1.1％，各薪材树种之间热值相差不大，铁刀木被选择为传统薪炭林更多是因为材质坚硬、收获运输方便、燃烧完全等特点。

混合程度由混合面粉颜色的一致性来确定。

Result: The genetic similarity coefficient was varied from 85.4% to 98.4%. The variation of protocorm, germination and monoleaf were rather more notable than that of bileaf and inflorescence.

结果：发现不同阶段内遗传相似系数较大，在85.409 3%～98.360 6%，其中在原球茎、萌芽期和一叶期存在的变异比两叶期、开花期要显著，但程度都极其微弱。

Test result makes clear, different intensity grade abandons the stuff of second birth wide market that gets after concrete mix up, of the compressive strength of concrete of second birth of different origin of compressive strength; that will reduce second birth concrete significantly all be worth concrete of singler source second birth to reduce, and variance and coefficient of variation increase; to use normal school model to be opposite of compressive strength of concrete of different origin second birth distributing undertook examining, use Monte-Carlo imitate method farther test and verify should distributing the rule.

试验结果表明，不同强度等级废混凝土混和后得到的再生粗集料，将显著降低再生混凝土的抗压强度；不同来源再生混凝土抗压强度的均值较单一来源再生混凝土减小，而方差和变异系数增大；采用正态分布模型对不同来源再生混凝土抗压强度的分布进行了检验，利用Monte-Carlo模拟方法进一步验证了该分布规律。
