In this paper, a new method was put forward of solving the malodor pollution by the sulfide giving off from the factory or the community.

这为解决含有硫系恶臭的工业废气及居民生活中产生的硫系恶臭的污染问题提供了一条新的治理途径。

For CaO-MgO-SiO_2-Al2_O_3-TiO_2 slag system, mass action concentrations model are established.

对于CaO-MgO-SiO_2-Al2_O_3-TiO_2五元渣系，建立了渣系的作用浓度计算模型。

Results 1555 mutation in the mitochondrial DNA was reverified to be one of the major factors which cause maternally inherited nonsyndromic deafness and the cosegregation of 955-960 and 1555 was present in this family.

结果再次证明了1555突变是该家系成员致聋的分子生物学基础之一；并发现该家系27名母系成员的线粒体基因组中除1555突变外，还同时存在有955-960同质型突变，两突变共分离。

The key mechanical parts and the pendulum series structure are deeply studied, and some mathematical models of the pendulum series motion are founded.

2深入地研究了重要机械零部件和摆系结构，建立了摆系运动的多项数学模型。

In order to find a powerful assistant computation tool for further analysis and design of multilayer optical coatings,an analytical model is mathematically established for accurate calculation of the first and second derivatives of the spectral coefficients of multilayer optical coatings with respect to layer parameters like thickness,real refractive index and extinction coefficient. It is based on the matrix theory of calculating the spectral coefficients of multilayer optical coatings and is achieved by perfectly using the trace operation of matrix.

为了寻找一种膜系深入分析与设计的有力辅助计算工具，从光学薄膜光谱系数的矩阵计算理论出发，基于对矩阵求迹运算的巧妙运用，从数学上建立了准确计算膜系光谱系数关于膜层几何厚度、实际折射率和消光系数等膜层参数的一阶和二阶偏导数的解析模型。

By the definition of Green-relation and the analogue of generalized Greens lemma, this paper first studied some properties of H-class、 D--class of rpp semigroups, then by left S-system 、-bisystem and tensor product, we described a blocked Rees matrix semigroup. Especially, the paper studied primitive rpp semigroups .

本文利用在rpp半群上定义的广义Green~(l-关系及相应的广义Green定理，首先研究了rpp半群H~(l-类、D~(l-类的若干基本性质，然后以左S-系、-双系和张量积作为工具，刻画了块Rees矩阵半群结构，最后从带零的本原rpp半群出发，构造出A型块Rees矩阵半群，并证明了一个半群S为本原rpp半群，当且仅当S同构于一个A型块Rees矩阵半群。

This year's Alumni Mentorship Scheme is welcome all graduates from the department of Statistics and Actuarial Science.

本年度的旧生师友计划欢迎任何香港大学统计系，风险管理系或精算系的毕业生参加。

This plate is to be tied over the miter with a violet ribbon in such a way that it rests on the front of the miter

用紫绳子将牌子系在礼冠上，即系在礼冠的前面。

And thou shalt tie it with a violet fillet, and it shall be upon the mitre

用紫绳子将牌子系在礼冠上，即系在礼冠的前面。

As a modeller, I certainly prefer the EX version to the MSiA one, which is like a toy for kids.

而可能 EX 系是针对小众模型迷而并非蓬迎玩具迷，故此部件的分色和夹口的吻合则稍逊於 MG 系模型。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
