It is learnt from the correlation analysis with the EMD decomposition results of Southern Oscillation Index that the upper ocean temperature variation of the DP might be effected by the surface air pressure variation of the decadal time scale in the tropical Pacific Ocean.

与南方涛动指数的年代际时间尺度分量的相关性分析结果表明，热带太平洋海面气压场的变化对德雷克海峡上层海洋温度的年代际变化有一定影响。

Acanthosis nigricans has received attention as a type 2 diabetes sign, but Dr. Bennett noted that this dermatologic condition may simply indicate increased insulin resistance. He emphasized that children with type 1 diabetes do have symptoms, while those with type 2 usually do not. Hispanic children, African-American children, and those of Polynesian heritage also seem more vulnerable to developing type 2 diabetes than white children, although obesity and being female clearly increase the risk in all ethnic groups, he said. Currently, there is no direct evidence that physical inactivity, separate from its effect on body mass index, is a risk factor for type 2 diabetes in youngsters.

黑色棘皮病因为是第二型糖尿病的一项病徵而受到瞩目，但Bennett医师表示，这种皮肤疾病可能仅代表胰岛素抗性增加；他强调，这在第一型糖尿病的孩童身上会有此症状，第二型糖尿病则否；他指出，虽然肥胖者与女性在所有种族中有明显地第二型糖尿病增加风险，但西班牙、非裔美国籍以及波里尼西亚人孩童比白人孩童更容易发生；目前没有直接证据证明，来自於缺乏运动对身体质量指数的影响，是造成年轻人发生第二型糖尿病的危险因子。

The increase of fluorescence index and protein-like fluorescence signal suggested that bacteria could play an important role in the production of chromophoric dissolved organic matter.

荧光指数的增大与类蛋白荧光的产生，显示微生物在有色溶解有机质的生产上起着重要的作用。

Last month, a UK insurance company Lucida announced the first longevity swap transaction based on the LifeMetrics index, agreeing to pay JPMorgan an income stream based on current longevity expectations in return for JPMorgan's promise to pay an income stream based on how long people actually live for.

上月，英国保险公司Lucida宣布了首笔基于LifeMetrics指数的寿命掉期交易，同意根据目前的寿命预期向JP摩根支付收入流，以换取JP摩根的承诺：根据人们的实际寿命支付收入流。

Therefore, the decrease of microbial diversity index with age was one reason why the quality of H. lupulus decreased.

随啤酒花植龄的延长，土壤微生物数量的变化，特别是微生物多样性指数的减少，可能是啤酒花品质下降的原因之一。

以我国季节冻土区关于标准冻深的统计资料为依据，用一元回归分析的方法建立季节冻土区黏性土标准冻深与冻结指数的相关关系的数学模型。

On the basis of observation on the incident and transmitted photosynthetically active radiation of the winter wheat canopy under the monoculture and intercropping ways, the diurnal change of interception photosynthetically active radiation, the relationship between IPAR and leave area index, and the shading of the winter wheat were studied.

文章摘要：通过对单作和间作种植模式下作物冠层入射和透射光合有效辐射的观测，研究了不同种植模式下冠层光合有效辐射截获量的日变化规律及其与叶面积指数的关系以及冬小麦对预留行的遮荫作用。

Linear regression analysis demonstrated that GI, whichrepresented phytotoxic behavior to the plants, could be poorly predicted by the sum of mobilemetal fractions (exchangeable +carbonate +reducible iron and manganese+ organic matter bound,EXCH+CAR+FeMnOX+OMB), i.e., Cu (EXCH+CAR+FeMnOX+OMB) in SS, Pb (EXCH+CAR+FeMnOX+OMB) in SM.

在用重金属有效性形态之和(交换态+碳酸盐结合态+铁锰氧化态+有机结合态，EXCH+CAR+FeMnOX+OMB)回归青菜与黑麦草发芽指数的方程中，只有污泥堆肥中的Cu和猪粪堆肥中的Pb与青菜及黑麦草的GI线性相关。
