半

In chapter 1, congruences on semigroups are always main subjects of semigroup theory.

第一章，半群上的同余一直是半群理论的研究主题。

A basic problem in the studying of operator semigroup theory is the relationships between semigroups and their infinitisimal generators.

算子半群理论中研究的一个基本问题是半群与其生成元之间的关系。

That is to say,the cold resistance of these trees had raised by exercise in winter. The difference of the semilethal temperature of the trees at the beginning of Sept.2003 was slight(-5.03～-6.08℃).

试验结果表明，12 月底采样树种的半致死温度低于9 月初采样树种的半致死温度，即经过冬季一段时间的低温锻炼，植株的抗寒性有所增强。

That is to say, the cold resistance of these trees were close.But the difference of the semilethal temperature of the trees in the end of Dec.2003 was remarkable(-9.86～-13.48℃). The difference of the cold resistance of different tree species raised by exer-cise in winter.

月初采样树种的半致死温度相差不大(-5.03～-6.08℃)，即未经低温锻炼时，6个树种的抗寒能力相近；而12 月底采样树种的半致死温度相差较大(-9.86～-13.48℃)，即经低温锻炼后，6 个树种的抗寒性差距增大。

Patients in the experimental group were applied with Nutrison Fibre as a kind of liquid diet in preoperative bowel preparation and postoperative early（ in 12 - 24 hours） enteral nutritional support. 21 patients in the control group made the bowel preparation by the traditional method of semiliquid -liquid- fasting with infusion and managed with ordinary process after operation.

试验组21例，术前3d口服能全力作术前肠道准备，术后12～24h开始以能全力进行早期EN支持；对照组21例，术前采用传统的半流食-流食-禁食补液方法进行肠道准备，术后给予禁食、输液-流食-半流食过渡。

For example, the eccentricity changes over time cycles of about 100,000 and 400,000 years, with the value ranging from less than 0.01 up to 0.05.[15][16] This is equivalent to a change of the semiminor axis of the planet's orbit from 99.95% of the semimajor axis to 99.88%, respectively.

例如，离心率大约在小于0.01至0.05之间变动，变动周期大约是10万年至40万年，这相当于行星运行轨道的短半轴相对于长半轴的比例在99.55%与99.88%之间发生变动。

The exact expressions of minimal martingale measure and the minimal entropy martingale measure for jump diffusion semimartingale are gained,with the specific changes of intensity and density function processes in these measures.

在跳扩散半鞅模型中，引进了跳的强度过程与跳的概率密度函数过程，研究了测度变换对跳的强度与密度函数过程引起的变化、研究了跳扩散半鞅的最小鞅测度与最小熵鞅测度。

Hamstrings – these are found to the rear of the leg and consist of the biceps femoris, semitendinosus and semimembranosus.

腿筋 -这些被发现后面的腿组成的股二头肌，半腱肌和半膜。

According to a completely randomized block design, 54 pigs (Larger White×Landrace) with an average weight of 53kg were assigned to three treatments. The diets contained the same amino acid pattern (TDLys : TDMet : TDThr : TDTrp=100 : 34.6 : 71.7 : 19.2) and digestibile energy levelDE 3200 kcalkg^(-1 with different crude protein levels (CP 10%, 18% and 26%, respectively). The trial lasted for 67 days before slaughter, and longissimus dorsi, psoas major, semaitendinosus, semimembranosus, arm triceps, glutaeus medius, the area, diameter and density of the muscle fibers were measured.

采用完全随机区组设计，54头53kg大×长生长猪随机分为3个处理（每处理3个重复），饲喂等氨基酸(TDLys：TDMet：TDThr：TDTrp=100：34.6：71.7：19.2)、等消化能DE 3200kcalkg^(-1和不同蛋白水平（CP 10%，18%和26%）的3种饲粮，饲喂期67d之后屠宰采样，测背最长肌、腰大肌、半腱肌、半膜肌、臂三头肌、臀中肌的肌纤维面积、直径和密度。

Study on lipid oxidation of Rugao ham during traditional past-ageing process: An investigation was carried out on oxidative processes of Semimembranosus, Biceps femoris and Subcutaneous fat in dry-cured ham during 12 months past-ageing storage.

后熟3个月后半膜肌酸价高于股二头肌和皮下脂肪，9个月半膜肌过氧化值显著低于股二头肌(p.05)和皮下脂肪(p.01)，说明后熟贮藏过程中肌肉、尤其是表面肌肉氧化高于皮下脂肪。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
