The model also features a truly extensive range of very different alternatives, also evidenced by no fewer than four specification levels (Argento, Oro Bianco, Oro Giallo and Platino), which will be able to satisfy premium customers of four types, each with their own tastes and needs: men, women, the young and the not so young.

该模型还具有非常不同的选择真正的，范围广泛，也证明了不少于4规范的水平（阿根，德奥罗比安科，德奥罗金麻和普拉蒂诺），将能够满足四种类型，用自己的每一个优质客户口味和需要：男人，妇女，年轻人和不太年轻的。

Aussies who reported watching four or more hours of TV a day were 46% more likely to die during a 6.6-year period than those who watched less than two hours a day, according to David Dunstan, PhD, of Monash University in Melbourne, and colleagues.

墨尔本墨娜大学的大卫邓斯坦博士和其同事进行了一项长达6年多的跟踪调查，结果显示那些每天看电视不少于4小时的人比每天看电视不到2小时的人死亡概率要高出46%。

It was estimated pulp properties with Runkel ratio more than 1 would be harder in tension for fiber and less oriented fiber to make paper into fluffiness (Casey,1980), with flexibility coefficient less than 0.5, the paper had medium tensile strength, burst strength and folding endurance, with slenderness ratio no less than 75 that be the paper of medium tearing strength but suitable beating with per cent of wall fraction less than 40 per cent would be good paper (Rydholm, 1967) while fibers completely oriented to get higher tensile and burst strength.

牙髓腔的财产据估计超过1比率将难以在紧张、纤维少使纸纤维成蓬松型、弹性系数低于0.5，该报中等抗拉强度、爆裂强度和耐折、与细比不少于75文件中被撕裂，但适当强度击打元墙上分数占不到40%将好的文件(rydholm， 1967)而获得较高的完全纤维拉伸强度和爆裂。

Sequence matching To achieve the coordinate system's unification between two point clouds, the key lies in calculating seven transformation parameters, which require not less than three homonymous points.

序列拼接实现两站点云之间的空间坐标系的统一，关键在于计算出转换模型中的七个转换参数，为此要求两站点云中存在不少于三对不共线的同名点。

Hydrazine Solution, at least 5% but not more than 64

On the basis of these treatments, the patients in the treatment group also had aerobic kinesitherapy through limb and trunk exercises with assistance to improve oxygen consumption of the body and increase the heart rate. In each session of exercise, the patients were supposed to attain the target heart rate of 70％ to 85％ of the personal highest safe heart rate.At the beginning, each session of exercise lasted for 10-15 minutes and the heart rate or pulse was measured every 4-6 minutes, with the patients'heart rate allowed to increase by no more than 20/minute and the patients not feeling tired. The subsequent exercise time gradually increased but not over 30-40 minutes, twice a day for no less than 5 days a week.

干预：两组患者均给予改善循环和营养神经药物等治疗，在此基础上，治疗组采用有氧运动疗法：以靶心率为指标，即以通过运动获得的个人最高安全心率70％～85％作为每次运动的靶心率，开始时每次运动10～15 min，每运动4～6 min测一次心率或脉搏，运动以患者心率增加不超过20次/min、患者感觉不疲乏为度，以后逐渐增加运动时间，直至每次活动持续时间30-40 min，2次/d，每周治疗不少于5 d。

The present invention discloses a polycarboxylic acid copolymer which is obtained by copolymerization of monomer components comprising a polyalkyleneimine unsaturated monomer (A2) and an unsaturated carboxylic acid monomer, the polyalkylene glycol unsaturated monomer (A2) having an oxyalkylene group bonded to a polyhydric alcohol residue, and the monomer component containing an unsaturated monocarboxylic acid monomer.

公开了一种多元羧酸共聚物，它是通过单体组分共聚制得的，所述单体组分包括聚二醇不饱和单体(A2)和不饱和一元羧酸单体，所述聚二醇不饱和单体(A2)具有使氧化烯基结合到多元醇残基上的结构，所述多元醇残基平均每个分子具有不少于3个羟基。
