For example, H, atomic weight of 100,794 hydrogen, carbon FC atomic weight of 1201, the atomic weight of oxygen O for 1594, Copper Cu for F63546 and so on. F history, had also used the other two kinds of "benchmarks", and there have been two kinds of scales used in parallel .1803 years, J Dalton published the first atomic table, the hydrogen-quality of the original F son as a "benchmark "requiring H, atomic weight is 1. In 1826, JJ Berzelius Tony F are presented to the quality of 116 oxygen atoms O as a" baseline "(scheduled for O, E atomic weight 16), which is has been in use to 1961 "Oxygen unit." 1929, found that the oxygen in nature, in addition to the greatest abundance of 16O, there are a small amount of slightly heavier 17O and 18O two kinds of isotopes, and the different sources of oxygen, its composition is slightly different.

It is included that 4-5 types of active sites exist in the catalytic system and the active site produced polymer with low molecular weight is easy to be activiated while TEA is used as the cocatalyst. While TIBA, the active site produced polymer with high molecular weight and seldom active site produced polymer with low one is prone to be activiated. MAO tends to activiate the active site produced polymer with middle-level molecular weight. In TEA-TIBA catalytic system, TEA and TIBA activiate the corresponding active site and the weight of every active site gradationally varied with the change of the ratio of the two cocatalysts. And the activity of the active site produced polymer with high molecular weight is proportion to the concentration of TIBA.

Methods 120 SD rats were divided randomly into blank group, model group, Baoliezhi control group and Qianliening granule groups with different doses. The models were established with hypodermic injection of testosterone propionate at 4 mg/kg after orchiectomy, at the same time, these rats were gastric perfused with different drugs respectively for 30 days. The body weight, prostate weight, prostate index, morphological changes, the level of T and E2 were measured. Results The body weight in model group was significantly lower than that in control group (P.05), the prostate weight and index were obviously higher than that in control group (P.01). The prostate weight and index were decreased significantly in Qianliening granule groups with meddle and high doses (P.01), the level of testosterone was increased significantly and E2 was decreased obviously in Qianliening granule group with high doses.

This article has selected three methods of weight calculation: single item index method of weight; synthesis index method of weight; entropy method of weight After the expatiation of theories and means, we analyzed example by using the fuzzy comprehensive evaluation method baaed on these three kinds of methods of weight calculation, and then came to the conclusion through contrast: the first method is very sensitive to superscale; the other two methods, which consider more factors' influence, can generally reflect the real status of water quality, and the results are consistent and relatively better.

The program of AER+RES was similar to AER, but went through resistance exercise 20min in base section of every exercise trail.Result: Prior to intervention, adiponectin levels were significantly correlated with BMI综合人成精品玖玖玖在线、 WHR、 COS国产精品黄色视频一、 LN激情小说图片亚洲、 LN、 TG国产精品黄色视、 LG10扒开女高中粉嫩小泬免费视频、 LN、 weight色色色干、 waist日韩高清黄免费一区、 FM、%F, and leptin levels were significantly correlated with BMI免费的av网、 WHR 国产片一区二区在线视频、 LN 、 LN 国产精品视频区1、 TG 二级片网站、 HDL-C 、 LG10A片黄片操屄、 apoB 国产一区二区男女激情视频、 apoA1/apoB、 waist三级天堂网观、 F1MWWW免费簧片AV网站COM、%F. Stepwise multiple regression analysis revealed that LG10; COS and waist was an predictor of basal adiponectin levels , and %F,apoB and WHR was an predictor of basal leptin levels. In early obesity, adiponectin and leptin can be worsened , along with the changed of body component, fasting plasm glucose and lipid accumulation. After intervention, both group were significantly reduction in FM,%F,weight, WHR,FPG and TG, while HDL-C had significantly increased.AER exhibited significant in leptin, while AER+RES did not show the change. Insulin and HOMA-IR were changed in both groups. The control group exhibited no significant change in any variables. Although adiponectin levels were unchanged in the three groups, a significant negativecorrelation between delta %F, delta WHR and delta FPG was observed. Futhermore, if compare the degree of delta weight, we fought a significant increased in adiponectin between the group of delta weight higher (=3kg) than delta weight lower(=0kg), delta %F, delta WHR and delta weight were significant negative correlation with delta leptin.
