Bubble nucleating and porosity were improved by adding lignin granule, and cell size of the polyurethane foam was decreased. Not only physical property but also thermal property of the material were enhanced. Compared with soft polyurethane foam, tensile strength of lignin reticulated polyurethane foam was raised by 140% at most which lignin content was 5%, and the heat-degradation temperature at the first stage was 50℃ more than soft polyurethane foam which lignin content was 10%. There had been a great improvement in heat resistance of the material. It was showed that weight of biological film reached to 10000 mg/L and 12100 mg/L when the lignin content of the polyurethane foams was 5% and 8% respectively via 30-day biofilm formation testing.

实验结果表明：1，4-二氧六环对木质素的溶解能力是最好的，可使木质素均匀分散在聚氨酯泡沫塑料中；木质素颗粒的加入可改善发泡过程的成核作用，提高聚氨酯泡沫的开孔率，降低泡沫孔径，并且能提高材料的力学、热学性能，与软质聚氨酯泡沫塑料相比，木质素含量5%的聚氨酯泡沫塑料拉伸强度最大可提高140%，木质素含量10%的聚氨酯泡沫塑料发生第一阶段失重的温度提高了50多度，材料的热稳定性大大提高；经过30 天的挂膜测试，木质素含量5%和8%的聚氨酯泡沫塑料的挂模量可分别达到10000 mg/L和12100 mg/L。

The hand-dug hole-filling pile is one of the most economic injection piles with large diameter.

人工挖孔桩是当今大直径灌注桩中最经济的桩型之一。

Cylinder, the cylinder sets of radial a surplus deformation of the cylinder sets a great impact on the cylinder liner reduced radial a surplus amount to reduce the deformation of the cylinder sets, the top surface of the body decreases roughness, but it will increase the body on the plane cylinder only mouth the roughness ; Preload reduced cylinder head bolt deformation of the cylinder liner little effect, the body can reduce the top surface roughness and cylinder body on the plane I ended roughness; Shen appropriate reduced cylinder head bolt hole deep can reduce the deformation of the cylinder sets, but will cause the body and the top surface roughness on the cylinder body only I roughness increases Plane .

工作工况下，对于第2缸来说，气缸套径向过盈量对气缸套变形影响很大，减小气缸套径向过盈量，有利于减小气缸套的变形，减小机体顶面不平度，但会增大机体上缸套止口平面的不平度；减小缸盖螺栓预紧力对气缸套变形影响很小，可减小机体顶面不平度和机体上缸套止口平面的不平度；适当减小缸盖螺栓沉孔深可以减小气缸套的变形，但会造成机体顶面不平度和机体上缸套止口平面不平度的增大。

Adopt a new exceed detect technology to ascertain hornitos under bottom terrane by super caliber manual excavate stake and weak terrane in this article, and the technology is economical, save time and nicety, and it s a reference for architects and buiders.

采用超前探测技术，确定大口径人工挖孔桩桩底岩层下的溶洞及软弱层是一种新的技术，既经济、省时，又准确，可供设计及施工人员参考。

Parts of the structure of a certain complexity, there are two spindle hole, and a large flat bottom, so parts of rough forming a gray iron foundry, cabinet parts is a typical parts, so its processing procedures and fixture design also has typical .

该零件结构有一定复杂性，有两个主轴孔，并且有底面的大平面，因此零件毛坯采用灰铸铁铸造成形，箱体零件是一种典型零件，因此其加工工艺规程和夹具设计也具有典型性。

Since the method causes serious depletion of ore during mining of upper plate,the inclined cutting raise heading together with inclined medium or deep hole kerve is suggested.

以无底柱为代表的崩落采矿法中，切割拉槽至关重要，而目前无底柱采矿大多采用垂直切割天井与切割平巷并配以中深孔联合拉槽的切割方法，但该方法在对矿体上盘回采过程中损失贫化较大。

Methods:The peptide sequences of human CYP1A2 were analyzed according to its bioinformatics, and synthesized on the basis of hydrophilicity, antigenicity, accessibility and flexsibility. The synthesized peptides were crosslinked with keyhole limpet hemocyanin, which was used to immunize rabbits for production of Ab.

利用生物信息学方法分析CYP1A2蛋白的序列，根据亲水性、抗原性、柔韧性及表面性等指标选择多肽序列，合成CYP1A2多肽，与载体蛋白钥孔戚血蓝素（Keyhole limpet hemocyanin， KLH）偶联，免疫日本大耳白兔制备抗CYP1A2抗体。

Methods PIWIL polypeptide was synthesized and conjugated to Keyhole limpet hemocyanin as an immunogen. Then PIWIL-KLH conjugations were injected into rabbits subcutaneously to produce polyclonal antibodies.
