"It is very important for patients, healthcare providers, and society to understand that there are many reasons for emotional distress and depression beyond a diagnosable major mood disorder," Dr. Muzina told Medscape Psychiatry, adding that other psychiatric conditions may be mistaken as major depression or bipolar disorder, and not every experience of emotional human suffering is a "mental disorder."

这对病患、健康照护者与社会来说都是非常重要的，要了解情绪紧绷与忧郁是有很原因的，且这超过了可诊断的重大情绪异常；Muzina医师向Medscape精神医学表示，其他精神疾病状况可能被误认为重郁症或双极性异常，并不是每一位经历情绪痛苦的人都罹患"精神异常"。

It is easy to see that the bialgebra H we find,canbe regarded as the enveloping algebra of a Lie algebra,whose generators are thoseof the Lie algebra of type A and n-1 other elements which commute with genera-tors above.

可以看出，我们找到的H作为代数，恰为在An-1型李代数上增加与之可换的n-1个生成元后得到的包络代数，其自然表示的矩阵元恰好生成代数AR。

Ma Jiantang, general director of China National Bureau of Statistics, stated on Thursday:"I have two concerns right now, one is how to maintain, protect and boost the constant economic recovery momentum as well as how to meanwhile curb the price in a mild and controlable scope; the other is the overquick rising price of some assets, e.g., the price of real estate in some places of some cities."

中国统计局局长马建堂周四表示："我的第一个担忧是如何既维持、维护、推进经济持续回升的势头，又把物价的上升控制在一个温和可控的范围内。另一个担忧是一些资产价格过快上涨，比如一些城市、一些地方房地产价格的上涨。"

Classifying and computing a QSIC (quadric surface intersection curve) are important operations in computing the boundary representation of a solid in solid modeling system, and also are applied in other geometric processing.

对两二次曲面交线(QSIC-Quadric SurfaceIntersection Curve)的拓扑分类和计算是立体造型系统计算三维物体边界表示的一个非常重要的操作，同时还可应用在其它的几何处理算法中。

In this paper we have found the main component s in a n -dimension random vector X , the so called main compon ents don′t contain linear relation and the others of X can be expressed as the linear combination of the main component s.

本文提供了在多维随机变量中寻找主成分的一种方法，证明了其余分量均可表示为主成分的线性组合，解决了多维随机变量的各个分量之间所存在的线性关系问题。

Gscoh gs fsR, gscoh as the solid fraction when the formation of the continuous dendrite framework, fsR as the maximum solid fraction after recalescence,βs as the solidification shrinkage of the primary phase,μas the dynamic viscosity of the liquid, a as the length of L/S coexistence zone,λ2 as the secondary dendrite arm spacing, and tf as the total solidification time. High temperature recovery and recrystallization taking place in these fragments during further cooling results in the further grain size decrease.

本文通过对过冷DD3高温合金再辉过程中累积应力的计算，得到作用于初生枝晶的累积应力σs，可表示为：式中，gl是液相体积分数，gs是固相体积分数，gscoh是连续枝晶网络形成点对应的固相分数，fsR是再辉结束后固相分数，βs是快速凝固中液固收缩率，μ为液态合金的动力学粘度，a是再辉中液固共存区长度，λ2是枝晶二次间距，tf是总凝固时间，即再辉时间。

Quantitatively: Reciprocal of the value of the angular separation of two neighboring objects which the eye can just perceive as being separate.

定量方面：任一空间分辨力的测定结果，例如观测者恰可察觉分离的两个相邻物体的用弧分表示的角度间隔的倒数。

Jiang Jianping of century interconnection vice-president expresses, after next generation IDC of use century interconnection serve, the client need not consider the physical position of resource, need to need to refer each according to oneself only " the task " can obtain fast, but custom-built Internet data center serves.

世纪互联副总裁蒋建平表示，使用世纪互联的下一代IDC服务之后，客户无需考虑资源的物理位置，只需根据自身需要提交各项"任务"即可获得快速的、可定制的互联网数据中心服务。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
