不常

Churg-Strauss syndrome is a systemic disease characterized by peripheral blood eosinophilia, necrotizing vasculitis of the small and medium -sized arteries, and intractable asthma.

Churg-Strauss症候群是一个全身性的疾病，在临床上常以周边血液的嗜伊红性白血球增加，坏死性的血管炎合并多器官的侵犯，以及不容易治疗的气喘为表现。

In Chapter 5, a scheme of the equilibrium iteration with a constant stiffness matrix is constructed by means of Steffensen's acceleration in the fixed-point iteration.

在第五章，我们利用不动点迭代的Steffensen加速方法构造了一个基于常刚度的平衡迭代格式。

In chapter 5, we obtain the invariant measure and the ergodic property of recurrent right processes.

在第五章里，我们得到了常返右过程的不变测度的存在性、唯一性及其遍历性。

And [29] had proved the existence and uniqueness of an invariant measure and the ergodic property for one-dimentional recurrent diffusion processes.

文献[21]和文献[29]，证明了一维常返扩散过程存在唯一的不变测度。

Clinical symptoms are abdominal heaviness, nausea, eructation, loss of appetite, especially abdominal pain, and discomforting evacuation.

临床以上腹部胀满、恶心、嗳气、食欲不振等为主要表现，常伴胃脘痛、大便不爽等症状。

Like America's estate duty it remains a levy on the amount left by the deceased and does not tax what individual beneficiaries receive.

美国在1916年开始征收不动产税，英国的遗产税紧随其后，它可以追溯到1964年征收的遗嘱税，在1894年已有现代雏形，从1986年开始，虽然与继承税没有什么相似之处，但大家仍常将二者搞混，比如说美国的不动产税，征收所有遗产中的一部分作为抵押品，而不是对接收遗产的个人受益者征税。

There were distinct nucleoli and abundant euchromatin. Little heterochromatin could be found.

细胞核内核仁明显，有大量的常染色质，几乎看不到异染色质。

Euchromatin stains more intensively than heterochromatin during nuclear division.

常染色质具有转录活性，因而可以进行蛋白质的合成，而异染色质通常不具有转录活性。

In this paper, we construct the differential equation to solve the unconstrained optimization problem. Such methods solving the ill-conditioned problems are very effective. It indicates that the asymptotically stable region of explicit the Euler method to solve the differential equation equals to the descent region of the gradient method to solve the original unconstrained optimization problem.

我们发现，在用Euler方法求解二次优化问题的等价动力系统的方程时，由方法的步长确定的稳定区域对应于这些方法所得到的迭代公式的步长满足单调下降算法的条件确定的单调下降区域，因此我们可以利用这个性质构造解无约束优化问题的数值方法而不采用标准的常微分方程的数值求解公式。

And he also celebrates the ever-present and, we hope, unquenchable human response.

他也颂扬了那种常存的，我们所期望不灭的人性回应。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
