Use D4 or DMC,vinyl di-blocking agent,ringy vinyl,hexamethyl-disiloxane as raw materials,tetramethyl hydroxyl ammonium as catalyst,we synthesized a vinyl silicone oil.

以D4，乙烯基双封头，乙烯基环体，六甲基二硅氧烷等为原料，四甲基氢氧化铵为催化剂合成了摩尔质量和乙烯基含量不同的乙烯基硅油；以高含氢硅油，含氢双封头，D4合成实验所需的含氢硅油；以白碳黑为填料通过密炼等工序制备了医用高透明液体注射硅橡胶。

Underneath the tights,this being to protect and also as a sort of a design you could viddy clear enough in a certain light,so that I had one in the shape of a spider,Pete had a rooker,Georgie had a very fancy one of a flower,and poor old Dim had a very hound-and-horny one of a clown's litso.

我们四人穿着时髦的服装，当时时兴黑色贴体紧身服，它缀有我们称为果冻模子的东西，附在下面胯裆部，也能起保护作用，而且把它设计成各色花样，从某个角度可以看得很清楚。

Porcelains are loaded and fired in the large sagger and charcoal is put into the separation between the sagger and the outer refractory bricks. The separation is locally Called "fire chamber".

匣底垫四块耐火砖，在大匣的外侧一定距离处砌耐火砖圈体，并在底部开几个孔(以炉体大小而定小孔的多少，俗称&爬火眼&)，用于爬退木炭来降低温度。

Veined,stockwork and alteration-sheathed gold ores have been found in the area,belonging to four genetic types:the volcanic hydrothermal ores related to early—middle Carboniferous volcanism; subvolcanic hydrothermal ores related to intermediate—acidic porphyry intrusions; hydrothermal ores to the granitic intrusion and dynamo- hydrothermal ores related to regional dynamic metamorphism along the faults.

矿石类型有含金石英大脉型、石英网脉型和蚀变岩型。矿床成因类型有4种：一为火山热液型，其成因与区内早—中石炭世火山作用有关；二为潜火山热液型，与中酸性斑岩体侵位有关；三为岩浆热液型，与花岗质岩浆的侵位有关；四为动力变质热液型，沿断裂带分布于蚀变玄武岩中，系区域动力变质作用的产物。
