Pre-molten refining slag is one of main research objects concerned by metallurgist currently, and the focused problem is how to choose proper refining slag in accordance to different steel grade.

预熔型精炼渣是目前国内外冶金工作者研究的重要对象之一，而根据不同的钢种选择合适的精炼渣剂及配方就成了目前研究精炼渣的突出问题。

Architecture description languages and their accompanying toolsets have been proposed as the answer. The XYZ/E is an executable linear temporal logic language. It can represent both dynamic and static semantics of systems. Basing on XYZ/E, the executable linar temporal logic language, we provide an architecture description language XYZ/ADL, which can represent both high-level abstract specification and the concrete implementation, thereby provides premise for the smooth transition from specification to implementation. And it can represent both the specification and the inner structure of a component under the unified logic framework, owing to the representability of the XYZ/E.

本项目研究旨在根据XYZ系统的特性，在时序逻辑语言XYZ/E的基础上，提出一种支持在XYZ系统中设计软件体系结构的描述语言XYZ/ADL，使之不仅能够对软件体系结构进行精确的形式化描述，而且为对其进行求精、验证、演化和分析提供基础，从而能在统一的时序逻辑框架下描述组件的规范和它的内部结构，并逐步过渡到最后的算法实现，从而能够支持软件开发设计的逐步求精全过程，把原有的两种支持软件开发的方法即支持模块化程序设计的方法和支持从规范到算法实现的逐步求精的方法有机地结合起来。

Instead, use a fruit oil, safflower, or sunflower oil instead.

可以用水果精油，红花精油或者葵花精油代替。

The consequence of annual changes of santolina essential oil and components would afford references to confirm the best harvest and take use of the compositions.

本文研究银灰菊精油含量和成分物质的周年变化规律，可为选择提取精油的最佳采收期，及开发利用精油成分物质提供科学依据。

The minimum spermicidal concentration being(0.05 mg/ml) in(3 min) of the sasanqua saponin sterilant was corresponded with nonoxynol spermicide and was lower than mandelic acid(0.1 mg/ml and citric acid(0.25 mg/ml.

结果 油茶皂素不育剂对雄性小鼠呈现出较优的剂量依赖性体外杀精活性，3 min时的最低杀精浓度为0.05 mg/ml，与人用杀精剂壬苯醇醚相当，比扁桃酸(0.1 mg/ml)和柠檬酸(0.25 mg/ml)低。

Results The spermicidal effect in vitro on male mice of the sasanqua saponin sterilant was provided with excellent positive relation in dosage-effect. The minimum spermicidal concentration being 0.05mg/ml in 3min of the sasanqua saponin sterilant was corresponded with nonoxynol spermicide and was lower than mandelic acid(0.1mg/ml) and citric acid(0.25mg/ml).

The role of nicotine smokers breathe in the production of sperm in the seminiferous tubules of spermatogenic epithelium to spermatogenic dysfunction, which produced a decrease in the number of sperm quality lower.

吸烟者吸入尼古丁作用于生产精子的曲细精管的生精上皮，使其生精功能减退，因而生产出来的精子数目减少，质量降低。

Bax protein was expressed mainly in spermatogoni and primary spermatocytes, and sometimes the expression was also seen in spermatids and spermatozoa within some seminiferous tubules.

Bax蛋白主要表达于精原细胞和初级精母细胞，部分曲细精管中的精子细胞和精子也有表达。

Tf in the seminal plasma level of determination, inhibin B Determination is the observation of Sertoli cells and the specific target in evaluated seminiferous speimatogenesis, and can be guide the diagnosis of male infertility treatment.

精浆中Tf水平的测定、抑制素B含量测定是观察睾丸支持细胞功能，评价曲细精管生精功能的一个特异性的指标，对男性不孕的诊断治疗具有指导意义。

A Sertoli cell resides in testicular seminiferous tubule, which is the only body cell contact with the spermatogenic cell, plays a crucial role of regulation in the process of spermatogenesis.

Sertoli细胞位于睾丸生精小管内皮，作为与生精细胞接触的惟一体细胞，在生精过程中起至关重要的调控作用。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
