The feasibility of determining the pentosan in pre-extraction liquor from eucalyptus chips by using Douglas colorimetric method was discussed in this paper. The visible spectrums of xylose, glucose, mannose, galactose and kraft lignin were compared under the same color reaction conditions. The results showed that the disturbance from hexoses and lignin can be eliminated when the pentosan is identified and determined by the maximal absorption at 553nm.

摘 要：探讨了 Douglas 比色法用于测定桉木半纤维素预提取液中戊聚糖的可行性，通过对木糖、葡萄糖、甘露糖、半乳糖和木素在相同条件下显色反应后的谱图进行比较，证明利用553 nm 处的最大吸收进行测定可以排除己糖和木素的干扰。

The 1%-Ni-doped TiO_2 calcined at 400℃has the best photocatalic ability.An indigo carmine solution of 10 mg/L was completely photodegraded in 50 minutes in the presence of as-obtained photocatalyst under visible light.A series of structure analysis,such as XPS,TEM,are employed to investigate the structure of the Ni/TiO_2 composite in details.The results indicate that at the lower temperature,instead of the simple interface compounding reported by some references,the Ni ions could be inserted into the crystal lattice of TiO_2,and form the innovative material.

The result of quantitative calculation for (0.4～0.8)μm wave band light radiation was directly used in the nuclear explosion subsystem, which took the visible light radiation to simulate the nuclear explosion. The experimental result indicates that more accurate measurement can be achieved with the atmosphere transmission software.

将（0.4～0.8）μm波段光辐射大气传输定量计算结果直接应用到基于可见光辐射探测的核爆炸探测子系统中，模拟核爆炸探测，实验结果表明：与传统大气传输计算软件的定性结果相比，该方法的测量精度有明显的提高。

This method is most special is the principle of simple and clear, setting out the process visible and tangible, it is applicable to a little bit knowledge of sheet l scene lofting geometry, which is a revolutionary approach, which not only greatly reduced the mapping workload, but also a great convenience in construction. Same time, it can also be a more traditional method (open show diagram drawing or galvanized sheet cut oil felt like, after re-opening in the pipe body gestures draw the cutting line method) is more accurate and pipe sections match exactly between the butt, thereby ensuring the steel fork tube and bend production quality.

该方法的最大特就点是原理简单明了，放样过程看得见摸得着，很适用于稍有一点几何常识的钣金工现场放样，这是一革命性的方法，它不仅大大地减少了制图工作量，而且也极大方便快捷了施工，同时它还可较传统方法（绘制开口展图后用油毛毡或镀锌板裁样再后在管身上比划绘出开口切割线的方法）来得准确无误与管段间对接严丝合缝，进而保证钢岔管和弯头的制作质量。
