Methods The p21 HBsAg/HBsAg transgenic mice(2,6,12, 18, 24 months) in SPF grade and corresponding p21 +/+ mice were dissected and the liver and hepatic tumor tissues were extirpated for the examination by histological HE staining and electron microscopy.

方法分别选取2，6，12，18，24月龄的SPF级p21HBsAg/HBsAg转基因小鼠和p21+/+野生型小鼠，剖检进行大体观察，取肝脏及肝脏肿瘤组织，进行组织学HE染色及电镜超微结构观察。

The effects of stimulation with electro-acupuncture on the pain threshold, 5-HT in brain stem, the β-END in hypothalamus and hypophysis, the β-END and ACTH in the blood plasma as well as the function of the cellular immunity of the normal rats, the hypophysis extirpated rats and the PHA injected rats were observed in this experiment. In the meantime, the pain threshold of rats injected with cyclophosphamide was observed too.

本实验观察了电针对正常、摘除垂体以及PHA大鼠痛阈、脑干内5—HT、下丘脑、垂体内β—END和外周血浆中β—END、ACTH含量以及机体细胞免疫功能的影响；同时，还观察了电针对Cy大鼠痛阈的影响。

Who should support us where our reason forsakes us?

我们没有仔细分析它，没有衡量它的全部分量，即它让我们承担的重大责任；我们只是从远处观察它，而从远处观察是靠不住的。

But the miniplate became even softer,still opaque and easy to break with some gabs on the surface six months later.The miniplate became into something like cheese,softer and exquisite twelve months later.

扫描电镜观察可见散在的比较表浅的小裂纹和凹槽；植入后6个月时，大体观察见接骨板表面已经变成白垩色，质硬，不透明，易折断，其上有裂纹。

The ultrasound apparatus is EUB8500, maked by Hitachi, ultrasound probe islinear array probe, 7.5-13.0MHz. After we hocused rats and fixuped them, weexamined rats with probe and forced gently. We controled the strength which keeped3 always and adjust the size of frame, and then observed the color within the frameand blue is electropositive.

将大鼠腹腔麻醉、固定，在超声仪下观察，手持探头轻轻加压，根据仪器指示，使压力始终控制在3左右，调整取样框大小，观察取样框内的颜色变化，蓝色为阳性。

When your scientists look into your night time skies, all they perceive is vast amounts of space between and imploding stars.

Before I begin with my story, I want you to detach yourselves from your individualities, so that you will be able to examine yourselves as I am going to examine Krishnamurti.

在开始我的故事之前，我希望你们把自己从你们的个人特征中分离出来，这样你将能够仔细观察你自己，正如我将仔细观察克一样。

Methods SD rats were used to make hemorrhagic shock model by 45% hemorrhage. Effects of Lactated Ringer's, hydroxyethyl starch alone or combined use with different volume on blood gas were observed. Meanwhile, the survival time was also observed.

SD大鼠放血45%复制重度失血性休克模型，分别观察不同量的乳酸林格氏液，羟乙基淀粉单用与合用对失血性休克大鼠血气指标的影响，同时观察动物的存活时间。

MethodsFocal cerebral ischemia was produced by permanent occlusion of the proximal of the right middle cerebral artery. The neurologic status of each rat was carefully evaluated at 24 h after surgery. The cerebral infarction numbers of neurons and nissls stains ,the water content were measured. Acute incomplete cerebral ischema was induced by ligaturing bilateral carotid arteries. Anoxia was produced by close normobaric hypoxia.

方法电凝大鼠一侧大脑中动脉造成局灶性脑缺血，观察脑血舒通对大鼠行为、大脑皮质内脑梗塞区神经细胞数量、尼氏小体含量、脑组织含水量的影响；采用结扎小鼠双侧颈总动脉形成急性脑缺血模型，并进行了小鼠常压耐缺氧实验，观察小鼠存活时间。

The degree of the plumping of the cattle hide and the removal of the hair were evaluated during the li- ming process;the protein,suspending substance,sodium sulfide and effective calcium oxide contents in the liming liquor and the fat content in the limed hide were measured;also,the tissue slice of the limed hide was observed by optic microscope.

将不同量的十二烷基硫酸酯钠、十二烷基三甲基氯化铵和平平加O分别添加到浸灰液中，观察浸灰过程中皮膨胀情况和毛脱除情况，测定浸灰废液中蛋白质、悬浮物、硫化钠和有效氧化钙含量及浸灰皮油脂含量，并对浸灰皮组织切片进行显微镜观察。

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。
