比重

The effect of the steel sector weight is more apparent in period of an expansion cycle compared to that in a period of a whole economic cycle. The hypothesis was further confirmed during the course of data sampling. Overall, in the various stages of the economic cycles, as the weight of cash deposit decreases, the expected return of portfolio amplify, while the overall risk raises as well.B. The optimal asset allocation strategy, which is subjected to the current rules and regulations, imposed the authority.

若进一步允许风险值趋近於0，适度增加风险以期获取更高报酬，实证显示全循环期与景气扩张期之债券投资部位略降，惟仍达82%以上，其中全循环期之股票类股比重由2.7%增加至9.8%，且由原配置在钢铁类股增加塑胶类股有分散类股之效果；而景气扩张期之股票部位由比重3.4%，经调整VaR值后，比重增加至15.5%，分别配置在钢铁类、金融保险、电子及塑胶等四类股以钢铁类股比重较高。

However, the overalldifferences in maximal spread only differed by one dermatome,with the hyperbaric solution achieving a median maximum sensorylevel to T3 compared with T2 for the isobaric and hypobaricsolutions.

然而，在最大扩散的总差别不同只有一节段，重比重溶液达到最大感觉平面的中位数 T3，而等比重和轻比重溶液达到 T2。

Wipe away the liquid overflown from the side tube with a piece of filter paper and put the cap immediately. Remove the pycnometer from the water bath and clean off any material on the outside with a piece of filter paper, weigh the pycnometer accurately and calculate the weight of its content.

然后将比重瓶自水浴中取出，再用滤纸将比重瓶的外面擦净，精密称定，减去比重瓶的重量，求得供试品的重量后，将供试品倾去，洗净比重瓶，装满新沸过的冷水，再照上法测得同一温度时水的重量，按下式计算，即得。

Some of the liquid spills out through the capillary constantly with the rise of the temperature of the content. Wipe away the overflown liquid with a piece of filter paper at any time until the fluid does not overflow anymore. Remove the pycnometer from the water bath rapidly. Proceed as described under method (1), starting from the words "clean off any material on the outside with a piece of filter paper…".

取洁净、干燥并精密称定重量的比重瓶，装满供试品（温度应低于20°C或各品种项下规定的温度）后，插入中心有毛细孔的瓶塞，用滤纸将从塞孔溢出的液体擦干，置20°C（或各品种项下规定的温度）恒温水浴中，放置若干分钟，随着供试液温度的上升，过多的液体将不断从塞孔溢出，随时用滤纸将瓶塞顶端擦干，待液体不再由塞孔溢出，迅即将比重瓶自水浴中取出，照上述（1）法，自"再用滤纸将比重瓶的外面擦净"起，依法测定，即得。

With the economic development and industrial structure restructuring in the past several decades, the industrial structure optimization of Beijing is obvious, the proportion of primary-industry and secondary-industry goes down gradually, and the proportion of tertiary-industry is increasing by a wide margin.

经济结构调整的核心是产业结构的调整，目前北京市的产业结构较以前有了较为显著的变化，呈现出了以下特点：第一产业和第二产业在整个产业中的比重逐步减小，而第三产业尤其是服务业比重大幅度提高，特别是第三产业的比重已经远远超过第一、二产业比重的总和。

Results:(1) The mean BMI of patients except for women aged from 20 to 29 years, was much higher than that of the general population (P.01).(2) The overweight (BMI≥24) ratio of the patients was much higher than that of the general population (P.01).(3) Patients with hypernormal BMI were more than those with normal BMI (BMI4) except for patients aged from 20 to 29 years.(4) Patients with hypernormal BMI were significantly more than those with normal body weight in all other occupations except for young students.

结果：①除了女性20岁～29岁年龄段外，其余各组患者体重指数的均数均明显大于中国普通人群体重指数的均数（P均＜0.01）；②本组患者中男、女性体重指数超常者(BMI≥24)所占的比重，均明显大于中国普通人群中体重指数超常者所占的比重（P均＜0.01）；③除了男、女20岁～29岁年龄段以外，其余各年龄段的患者中体重指数超常者所占的比重，明显大于体重指数正常者(BMI4)所占的比重；④除青年学生外，其他职业中体重指数超常者所占的比重，明显超过体重指数正常者所占的比重。

The deep cultivation-root cutting in before winter stage would increasethe weight and ratio of root system in middle and lower layer,the resultswould decrease the root redundancy.

冬前深耘断根可增加中、下层根系的重量和比率，降低根系生长冗余性，控制最高总茎数，提高成穗数及成穗率，使籽粒产量中来自花后光合器官输送的比例增加，从而使产量提高，因而在旱地高产麦田应推广冬前深耘断根。6研究了降水量对旱地高产小麦耗水规律及产量的影响，拔节前降水多且占比重高，土壤供水量及占比重少，拔节后降水量减少且占比重低，土壤供水量及占比重高，利于在旱地高产麦田形成高产。

本文采用了Hummels等人估算垂直专业化比重的方法，利用中国1987年-2002年的投入产出表，对中国出口贸易中垂直专业化比重做了分行业测算；此外又计算了美国1998-2004年出口贸易中垂直专业化比重和14个典型国家2000年垂直专业化比重，并将其结果与中国垂直专业化程度进行对比。

With the usage of the method of estimating the vertical specialization proportion by the Hummels and the input-output sheet of China from 1987 to 2002, a estimate on the vertical specialization proportion of China's exportation has been done. Furthermore, the vertical specialization proportion of exportation of America from 1998 to 2004 and another 14 typical countries in 2000 has been estimated and compared with China.

The particles with heavy specific gravity are discharged from the underflow mouth and those with light specific gravity are discharged through the overflow pipe and thus it realizes the separation for heavy and light particles.

流体自旋流器上端给入并在旋流器内形成强制旋转流，旋转流将颗粒按粒度和比重分为内外环层，当矿浆流动至锥体部分时，由于锥体的突然变向，阻力增大，颗粒群向下运动的趋势减缓，并在此形成旋转悬浮层，随着离心力场的减弱，重力作用越来越明显，由按粒度和比重分成的内外两层逐渐转化为按比重分选的上下两层，比重大的颗粒通过底流口排出，比重小的颗粒则通过溢流管排出，从而实现轻重颗粒间的分离。

I didn't watch TV last night, because it .
