Using 60Co γ-rays and 70～180 keV X-rays,the test results show that saturation characteristics of the cavity ionization chamber meet the requirement of DIS detector. Direct Ion Storage detector,tissue-equivalent cavity ionization chamber,MOS field effect transistor,saturation characteristic curve

本文从探测器原理出发，设计与研制DIS探测器中组织等效空腔电离室，重点从壁材料、气体成分、腔体形状和尺寸、壁厚度以及绝缘材料等角度，测试电离室辐射性能，以为研制新型DIS探测器奠定基础。1DIS探测器原理图1直接电

In the present study, the relationship between transmural posterolateral scar tissue and response to CRT was evaluated.

本研究旨在评价后侧壁透壁性瘢痕组织与CRT疗效的关系。

It is confirmed that the treatment with laser is based mainly on photo-thermal interaction. And blood coagulation, vasoconstriction and vein occlusion are realized by the thermo scathe of blood and vascular with laser irradiation. Finally vascular diseases are cured.

论证了光热作用是激光治病的主要依据，激光通过照射病变血管，造成血管内的血液及血管壁的热损伤，从而达到血液的凝结，血管壁的收缩，血管闭合，实现了血管病变的治疗。

利用氦气在不同压力下具有不同的状态参数和热力参数，可以通过传热方法测量包壳内的氦气压力。1试验装置和研究方法如图1，把燃料棒浸入到一个高温的池子内，热量会在燃料棒内传递开来，通过测量管壁外面不同位置出的壁面温度，就可以推测到包壳内的氦气压力

Further comparison of the vascular bundle sheath sclerenchyma cell deterioration in separate plants infected with an additional four CTV isolates, CTV-2, T-TX8, T-TX9 and T-TX24 showed that there were significant differences in scleranchyma cell deterioration in principal lateral vein, midvein, petiole, and healthy control with all four CTV isolates (P=0.000 1, F=80.60, df= 47). Healthy plants had no such sclerenchyma cell deterioration.

CTV-2、T-TX8、T-TX9 、T-TX24等另外4个柑橘速衰病毒株系分别侵染后，主支脉、中脉、叶柄维管束鞘厚壁细胞的衰退与对照差异显著(P=0.000 1， F=80.60， df= 4，7)，健康植株厚壁细胞没有退化。

The effect of BBS on cell spreading was detected by cell scratch test and millicell test. Results Proliferation of PC-3 and DU-145 cells was observed with different concentrations 10^(-10-10^(-5)mol/L. The cell growth could be inhibited by BBS receptor antagonist. In addition, teleconcentration 10^(-6)-10^(-5)mol/L BBS could stimulate cell adhesion and spreading best.

结果 ①不同浓度10^(-10-10^(-5)mol/L的BBS可促进细胞增殖，并呈现一定浓度依赖性，而其受体拮抗剂具有相反作用；②终末浓度10^(-6)-10^(-5)mol/L的BBS提高细胞贴壁率效果最佳，其受体拮抗剂则降低细胞贴壁率；③不同浓度的BBS可提高细胞播散能力。

Methods Twenty-two pieces of temporal bone were taken for this study. The mastoid cavity was opened, scutum removed,"bridge" broken down, posterior wall of external auditory canal abraded and the related anatomic structures were fully exposed. The distance between the origin of facial nerve canal and the anterior border of round window （ OOFNC-ABORW ）, between the highest point of the facial nerve canal and the bottom of posterior mastoid sinus,and between the stapes head and round window niche was measured under operating microscope.

方法取成人颞骨22侧（左右各11侧），用耳科钻磨开乳突腔，去上鼓室盾板、断"桥"，磨低骨性外耳道后壁，充分暴露相关结构，在手术显微镜下测量面神经管垂直段起始部前缘至圆窗龛前缘的距离、面神经管最高点与后鼓室底壁之间的距离、锥隆起的高度（即锥隆起基底到锥隆起顶端的距离）、镫骨头至圆窗龛前缘的距离。

A matrix display device comprises cavities (20) having walls at least one of which is covered with a material (24) having a secondary emission coefficient of more than unity.

一种矩阵显示装置，包括具有腔壁的空腔(20)，所述腔壁中至少一个腔壁上覆盖了具有大于单位一的二次发射系数的材料(24)。

The distances of the posterior semicircular canal and the groove of sigmoid sinus to the adjacent structures were measured. Results A.

结果 CT扫描测量乙状窦沟宽是(11.44±1.79)mm，深是(5.27±1.93)mm，乙状窦沟底到乳突外表面的距离是(10.38±3.90)mm，乙状窦沟前壁到外耳道后壁的距离是(13.66±2.18)mm。

Climb up the ledges, shimmy right, and jump up to the next ledge and the next ledge.

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。
