The mutants were further screened through repeated fermentations as well as the measurement of their physical properties. The results showed that some major fermentation indexes of strain HJ1615-d4 such as alcoholicity, fermenting power,total acids and flavoring components etc. were almost the same as those of the original strain. However, its urea yield was only 15.41 mg/L, louer 50 % than that of the original strain.

对这4株突变株进行发酵栓实验，并测定其发酵综合性能，其中菌株HJ1615-d4在发酵力、总酸、酒精度以及风味物质等综合指标方面保持了亲株的优良性状，同时产尿素的量为15.41 mg/L，低于出发菌株产尿素量50 %以上。

The results showed that the addition of 10 U/g cellulase in the residual distiller′s grains could effectively increase the content of reducing sugar after 5 h water bathing in water bathing pot at 58 ℃, the alcoholicity by the fermentation of the residual distiller′s grains could reach 4.67 %vol, and liquor yield could reach 31.39 %(increasing by 2.61 % than untreated distiller′s grains).

结果表明，在残糟中添加纤维素酶10 U/g，于58 ℃的水浴锅中保持5 h，可以提高还原糖的含量，残糟发酵酒精度达到4.67 %vol，出酒率达到31.39 %，出酒率比原糟提高了2.61 %，蒸馏出的产品达到蒸馏白酒各项卫生指标，达到优质酱香白酒的要求，提高了酱香型白酒酒糟的利用价值。

The company has a group of experienced and skilled researchers, at the same time with Honeywell, Hengye International, Japan ALEPH Group and other international co-operation and continued to introduce the latest scientific research, and constantly develop new products, new technologies, in order to maintain the company's leading position in science and technology.

公司拥有一批经验丰富、技术精湛的科研人员，同时与Honeywell、恒业国际、日本艾礼富等国际集团企业合作，不断引进最新科研成果，不断开发新产品、新技术，以保持公司的科技领先地位。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
