选用含有2个变分参数的波函数，利用变分法计算了无限深球形量子点中施主杂质态的束缚能、杂质有效玻尔半径、维里定理值等随量子点尺度的变化关系。

The commonly used cluster based segmentation method assumes that the sample distribution is hyperspherical, but this kind of assumption is not consistent with the real characteristic of the human brain MR image.

通常使用的聚类分割方法认为样本的分布是超球形的，然而，这并不符合人脑磁共振MR（magnet－icresonance）图象的真正特点。

Seeds and ovules many; capsules usually subequaling or longer than sepals, often ovoid; stamens (2--)10, hypogynous or perigynous.

种子和胚珠很多；蒴果通常近相等的或长于萼片，通常卵球形；雄蕊(2-)10，下位或周位。

Stamens hypogynous, as long as corolla tube; filaments basally expanded; anthers linear. Ovary ellipsoid, ovoid, or pyriform.

下位的雄蕊，倍于花冠筒；基部的花丝膨大；花药线形子房椭圆形，卵球形，或者梨形。

In the aggregation process of polymer chains, when the time scale for the chain impenetration is far shorter than that for the chain collision, the polymer chains will aggregate to form spherical clusters.

对于高分子单链的聚集而言，当链贯穿的时间尺度远小于链碰撞的时间尺度时，链在聚集时就会相互缠结形成球形的聚集体。

On the one hand, The empirical model is remedied to investigate themicrowave emissivity of sea surface under wave breaking. In this model, we havediscussed the effects of spherical bubbles and droplets of whitecaps and difference intemperature between air and sea water on the emissivity of sea surface. Themodel results indicate that the effective seawater emissivity increases with DTBASincrease.

在被动遥感方面提出了一个改进的研究海浪破碎产生白冠时海水有效发射率的模式，讨论了白冠层中主要成分为球形气泡和水滴的情况，并着重分析了海-气温差对海水发射率的影响，研究表明海水发射率随着海-气温差的增大而增大。

Inflorescences terminal, shorter than cauline leaves; involucral bract leaflike; heads many, hemispheric, many flowered.

花序顶生，短于茎生叶；总苞片叶状头状花序很多，半球形，多花的。

The results show that the material achieves quite high thermal conductivity of 116 W/, when the carbon black is round and isolatedly distributed in the base material, and the soaking time is 4-6 h.

结果表明，以球形孤岛状分布的炭黑使材料具有较高的热导率，达到116W/；保温4~6h为较佳的工艺条件。

A few years later Keeling observed a second cycle: a hemispherical seasonal cycle of CO2, low in summer and peaking in the winter for the same reason CO2 peaks at night: no greens at work to eat it.

几年后基林观察到了二氧化碳的第二个循环特征：二氧化碳的半球形季节循环，浓度在夏天最低，在冬天达到高峰，和二氧化碳的浓度在晚上达到高峰值的原理一样，没有绿叶的光合作用消耗二氧化碳。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
