内积

Periodic signals which are neither absolutely integrable nor square integrable over an infinite interval, can be considered to have Fourier transforms if impulse functions are permitted in the transform.

若在变换过程中可以使用冲激函数，那么，在一个无限区间内，既不绝对可积，又不具备平方可积的周期信号也可以认为具有傅立叶级数。

It is proved that the Bottom Aquifer was composed of diluvial alluvial deposition and beds bearing gravel were mainly formed by rapid mud rock flow in fault basin...

各矿区的底含皆形成于气候干暖的新第三纪中新世，是一套在中、新生代断陷盆地内的山前洪积扇上由快速水流形成的洪积-冲积物，含砾石地层多为泥石流沉积物

If, as often happens, the effusion develops rapidly over several days, increasing dyspnoea will be a prominent feature, but in cases which the effusion develops gradually it may have scarecely any effect on the symptoms already present.

如果像常常出现的那样，积液在几天内迅速发展，呼吸困难不断加重将是一个突出的特征。但在积液逐渐发展的病例中，它对原有的症状很少产生影响。

The direct signs of Pulmonary embolism were luminal constriction,emphraxis,branched decreased,intraluminal lowD filling defect of blood vessel;while the indirect signs,formation of pulmonary infarction focus,pleural effusion,pneumonia,atelectasis,pulmonary dilatation and hydropericardium,etc.

肺栓塞的直接征象为管腔狭窄、阻塞、分支减少及血管腔内的低密度充盈缺损，间接征象为肺梗死灶形成、胸腔积液、肺炎、肺不张、肺动脉增宽、心包积液等。

肺栓塞的直接征象为管腔狭窄、阻塞、分支减少及血管腔内的低密度充盈缺损，间接征象为肺梗死灶形成、胸腔积液、肺炎、肺不张、肺动脉增宽、心包积液等。

Its etiopathogenisis may be the operation wound, the inflammation, fluidify, hematocele or the foreign object in abdominal cavity result in edema calidum in the bowel, and the effusion in ectoptygma surface increased. These lead to a series of immune response and cause to the adherence in peritoneum. The treatments such as fasting, gastrointestinal decompression, nutrition support, antiinflammatory, enema of chinese crude drug and surgery could get good effect.

可能的发病原因是手术创伤、腹腔内炎症、积液积血或异物刺激导致术后小肠出现炎性水肿，浆膜表面渗出增加，产生一系列免疫反应，造成腹膜间粘连而成，采用禁食、胃肠减压、抗炎、营养支持、中药灌肠或手术等疗法，效果良好。

The coefficient of variation CV was lower than 5%, and comparing with that of ektacytometry, we found that there was a good correlation between the measuring results of the two methods.

该测量方法虽受红细胞压积和悬浮介质电导率的影响和限制，但只要在仪器测量范围内，严格控制压积的一致性，其测量的重复性和准确性是可以保证的。

PZT (50/50) thin films were prepared by metallo-organic compound decomposition method using lead acetate, titaniu m-n-butoxide and zirconium oxychloride on Pt/SiO〓/Si substrates.

其基本淀积条件为：微波功率500W，反应压力0.4Pa，衬底温度100℃，气体流量30～50 SCCM，此条件下薄膜的淀积速率大于15nm/min，8英寸直径内均匀性优于97%，折射率分别在1.93、1.47和1.47～1.92。

METHODS: Fiftynine patients, who were diagnosed as having malignant thoracic (n= 46) or pericardiac effusion (n=13), were divided into two groups at random: Minimaltrauma tube installation group (n=29) and routine puncturing group (n=30). Cisplatin (45mg or 10 mg/m2) was injected into the cavities of the subjects.

对临床确诊的恶性胸腔积液(n=46)和心包积液(n=13)患者，随机分为微创置管组(n=29)和常规穿刺组(n=30)，同时于胸腔或心包腔内注入顺铂(45 mg和10 mg/m2)。

The sufficient and necessary conditions which Fuzzy subalgebra of direct product Boolean algebra can be decomposed as direct product of two Fuzzy subalgebras are obtained.

进而分别定义了在对偶模意义下直觉模糊群的外直积与内直积。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
