Bg ,is known as "the king of the watch "it is because that the founder louis bg had invented many things about the watch ,for example the innovative Tourbillon ,"the hand of the bg "and so on .all the patterns are made of more than 18k gold noble metal crust ,crocodile waistband ,silverplated dial plate ,which are fantabulous .unfortunately it is regretful that its style is a little consertive ,most of their dial plate are rotundity ,short of diversification .

宝玑，BG。号称"表王"，主要是因为其创始人路易。宝玑先生有着太多的关于腕表的第一次发明，比如创世纪的陀飞轮和"宝玑指针"等等。所有款式均用18K黄金以上的贵金属制造外壳，以鳄鱼皮表带为主，而且表盘通常以镀银处理，非常漂亮。只是有一点点的遗憾，就是外形款式有点儿保守，大多为圆形表盘，缺乏变化。但是，无论如何都是世界级的名表！

It is concluded that the ultrafiltration preconcentration combining with multieffect evaporation is a promising concentration procedure for straw black liquor, which can not only reduce the concentration costs, but also improve the subsequent evaporation and combustion operation due to the desilicification and purification of ultrafiltration.

两种膜比较，磺化聚砜膜更易清洗，而且水通量大。5）超滤浓缩后，黑液中木素的浓度和纯度大大提高，超滤是从黑液中分离木素的理想方法。6）与多效蒸发相比，用超滤法浓缩麦草黑液可降低能耗70~85%，若用于黑液的预浓缩，再结合多效蒸发，不仅可以降低黑液的浓缩费用，而且由于除硅和纯化作用，会大大改善后继的蒸发和燃烧的操作。

Again the king was the chief figure; again there were tumult and shouting; again there was heard the cry for more victims; again there were black scaffolds; and again the scenes of the day were closed by horrid executions; Louis XVI, struggling hand to hand with his jailers and executioners, was dragged forward to the block, and there held down by main force till the ax had fallen, and his dissevered head rolled on the scaffold.

&国王又是其中的主要人物，那时也有骚乱和呼叫；又有杀了再杀的喊声；也有黑色的刑架；又是以可怕的死刑结束那一天的节目。那一天路易十六与禁卒和刽子手角力挣扎，结果被拖到断头台上，用强力被按倒在地，直到大刀落下，他的头颅滚到台下为止。&法王还不是唯一的牺牲者；靠近那一带地方，在恐怖时代血腥的日子里，竟有二千八百人死在断头台上。
