用任何方法或形式,在两个或两个以上的主体(如人或电脑)传递、交换或分享任何种类的信息的任何过程,就叫做沟通.要完成一个项目,需要具备各种才能和素质的人,由此产生了对组织或团队的需求,因此组织的成员都必须与他人共事.而沟通则是实现"共事"的必要条件.没有沟通就无法传达任务,组员不明确任务就无法工作.沟通要定位清晰,采取恰当的沟通渠道和方式,要以尊重他人为前提进行沟通交流,了解他人的性格个性,多倾听,鼓励,提高交谈技巧,表达要清晰.恰当的、及时主动的沟通能够避免软件项目开发中不必要的失误. 相似文献

在当今的时代背景下,每个家庭只有一到两个孩子,随着人们生活的日益富足,越来越多的父母开始更加注重孩子的成长与未来,从某种角度上说,孩子的发展质量就预示着家庭的将来。不少年轻的父母"恨铁不成钢",省吃俭用,在孩子身上盲目投资,上各种培训班,学各种专业技能,期待把孩子培养成"绝世全才",但这股一浪高过一浪的风潮中却隐藏着一定的隐患,家长的选择不适合孩子的实际,选择的专业之多让孩子不堪重负, 相似文献

为解决降低成本,拓宽矿源的目的,对高铝矿终渣进行了细致且系统的研究。通过对黏度曲线的测量,动力学活化能的计算,热力学计算的手段,分析炉渣各组分析出规律及其变化,得出结果:炉渣稳定性与成分有较为紧密的关系,各超大型高炉炉渣成分相差不大,但黏度随温度变化规律确是大相径庭;一般来说,超大型高炉高温时炉渣活度差异较小,在160000~170000J,而在低温时活化能的变化率差异较大;高铝低镁渣的稳定性超过高铝高镁渣,如果能够使高炉中的镁降低可以大幅度提高炉料的冶金性能,降低渣量,是降低成本的有效措施;降低终渣中的镁含量不是否定镁对炉渣稀化作用,恰恰相反,提高渣中镁在液相中的作用效率;高铝渣未必就一定不稳定,应适宜调整炉渣其他组分,使高炉适应高铝渣操作。 相似文献

1需求形势据国外媒体报道,2003年全球制造业对白银的需求量已上升到24358t,扭转了前两年连续下降的趋势。同时,白银的市场价格也平均上涨了6%。报道说,由于全球电子工业生产的上升和经济环境的好转,2003年,全球工业应用白银的数量增长了3%,达到9957t。中国2003年的白银消费量达到它空前的高水平,制造业对白银的需求量实际上升8%,工业用银数量达到了782t。报道说,首饰和银制品是消费白银的主要市场。2003年,这方面对白银的需求量增长了4.1%,实际用银用达到了7844t。增长幅度最大的是中国和泰国,中国上升22%,泰国上升13%。具有白银首饰消费传… 相似文献

据国外媒体报道,2004年,南非的黄金生产降到了1931年以来的最低点——342t/a。从1885年南非矿山协会开始对采矿业建立官方统计以来,每年出口额最大的是黄金。现在,这个状况已经发生了变化,铂族金属的出口额已经超过黄金,占第一位。2004年,南非的矿业生产总额是1250亿兰特,黄金产值占293亿兰特,落后于333亿的铂族金属,居第二位。当年南非煤炭产值是276亿兰特。1970年代,南非的黄金产量是1000t/a,占当年全球矿山新生产的黄金的70%左右,一段时期以来,南非的黄金生产以每年5%的速度萎缩,而且近几年来,由于南非货币兰特处于强势,使这种萎缩的速度… 相似文献

The lipid and protein composition of the perivitelline fluid of the eggs of Pomacea canaliculata was investigated. Two lipoproteins (PV 1 and PV 2) and one lipoprotein fraction (PV 3) were detected for the first time in gastropods. They represent 57.0, 7.5, and 35.5% of the egg total proteins, respectively. PV 1 is a glyco-carotene-protein complex with characteristics of a very high-density lipoprotein (VHDL). It has 0.33% lipids, mainly free sterols and phospholipids. The particle has a MW of 300 Kd and is composed of three subunits of 35, 32, and 28 Kd, respectively. PV 2 particle is a VHDL of 400 Kd and 3.75% lipids. The major lipid classes are free sterols and phospholipids and also have significant quantities of energy-providing triacylglycerides and free fatty acids. It is composed of two apoproteins of 67 and 31 Kd. PV 3 density corresponds to a high-density lipoprotein (HDL). It was fractionated into two subfractions "h" and "p". Fraction "h" contains 5.16% lipids, mainly free sterols, phospholipids, and free fatty acids, and two particles of 100 and 64 Kd. Dissociating electrophoresis showed two subunits of 34 and 29 Kd. Fraction "p" is composed of a single particle of 26 Kd that contains 9.5% lipids, which represents 30% of the total egg lipids. It has high levels of a carotenoid pigment. Besides it contains free fatty acids, hydrocarbons, sterified sterols, and triacylglycerides. These three fractions are probably the major supply of lipids and amino acids for the developing embryo. 相似文献

Alterations in core lipid composition of lipoproteins in noninsulin-dependent diabetes mellitus (NIDDM) patients have suggested that the heteroexchange of neutral lipids between HDL and the apo B-containing lipoproteins may be enhanced. For this reason, we studied cholesteryl ester transfer (CET) in ten sulfonylurea-treated patients with stable NIDDM. CET measured in all NIDDM subjects with an assay of mass transfer was significantly greater than that of controls at 1 and 2 h (P < 0.001); the transfer of radiolabeled CE also was increased in a subset of four of the NIDDM group (NIDDM k = 0.21 +/- 0.04 vs. control k = 0.10 +/- 0.05; P < 0.05). A weak correlation was demonstrable between the mass of CE transferred at 1 h and diabetic control expressed as plasma fructosamine (r = 0.58, P < 0.09). To characterize this disturbance in CET further, the donor (HDL + VHDL) and acceptor (VLDL + LDL) lipoprotein fractions were isolated by ultracentrifugation at d 1.063 g/ml from NIDDM and control plasma and a series of recombination experiments were performed. Combining NIDDM acceptor with control donor fractions that contained HDL and CETP and not the combination of NIDDM donor and control acceptor lipoproteins resulted in an accelerated CET response identical to that observed in NIDDM whole plasma. This observation indicated that the abnormality in CET in NIDDM was associated with the VLDL + LDL fraction.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献
