天麻、刺梨、蜂蜜复合发酵酒以刺梨、天麻、蜂蜜为主要原料，将天麻、刺梨分别榨汁，混合调酸，用蜂蜜调糖，经加热、杀菌、冷却后接种训化培养后的酒母，前发酵7d，后发酵20d，再经澄清、过滤、杀菌即得天麻、刺梨、蜂蜜复合发酵酒。

The article gives a design of an NIR instrument with filter. The working theory of the instrument is: during wheel running a circle , ray from light source irradiates the sample after it through a certain filter of filter wheel, so ray would carry the absorption spectrum of sample . We can know components of the sample by analyzing the ray . Filter wheel is its light splitter.

本文给出了一个使用滤光片作为分光器件的近红外光谱仪的控制电路设计方案，其工作原理是：当滤光轮转动时，光源出射光经过滤光轮上的某一滤光片，再照射到样品上，经样品池出射的光携带有样品的吸收光谱信息，滤光轮转动一圈，可得到样品不同波长处的光谱信息，通过后期数据分析可得到样品的成分含量信息。

Finally, it joint the method of keyword search that aim at the field of subject and from to construct white-list and black-list, then to use PNN to E-mail classification whether increasing accuracy rate.

最后加入关键字搜寻，针对邮件主旨及寄件者名称，建构黑白名单过滤，再配合机率类神经网路对电子邮件分类，看其评估准则是否提升。

The method comprises: adding 4-(3,4-dichlorophenyl)-1-tetralone and solvent at a ratio of 1:(3-4) into a three-necked flask with a stirrer, heating under stirring until 4-(3,4-dichlorophenyl)-1-tetralone is completely dissolved, heating to 60-100 deg.C, refluxing for 0.5-2 h, cooling the filtrate to -5-10 deg.C, filtering, recrystallizing to obtain refined 4-(3,4-dichlorophenyl)-1-tetralone, and drying at 40-80 deg.C to obtain dry 4-(3,4-dichlorophenyl)-1-tetralone.

该方法的步骤是：在带搅拌的三颈瓶中依次加入4-(3，4-二氯苯基)-1-萘满酮和溶剂，溶剂与4-(3，4-二氯苯基)-1-萘满酮的L∶W为3～4∶1，将上述4-(3，4-二氯苯基)-1-萘满酮及混合精制溶剂搅拌下升温，使4-(3，4-二氯苯基)-1-萘满酮全部溶解，升温至60～100℃，回流0.5-2h；滤液用冰水冷却至-5～10℃，过滤，所得物料再用上述方法进行一次重结晶得到精品4-(3，4-二氯苯基)-1-萘满酮，40～80℃干燥后即得到干品4-(3，4-二氯苯基)-1-萘满酮。
