不定型

Most present gravimeters are of the unstable or astatic type.

多数现有重力仪为不稳定型或无方向型。

Ti-Si composite materials are mixed at atomic scale, and Ti-O-Si bond appears in all of the samples with different TiO2 content; the mixed oxides are mainly existed in the form of amorphous pattern, anatase appears when the TiO2 content is more than 80%, but compared with the intension of pure TiO2, it has not integrate structure. The acetic content has great influence in the specific area and crystal structure of the mixed oxides. 20TiSi has good heat stability, still possesses 11m2/g after calcined at 1100℃; calcinations on the large scale of temperature does not cause the break of Ti-O-Si bond, TiO2 is well dispersed in 20TiSi calcined at 1100℃, and it still existed in the form of amorphous.

结果表明：制得的Ti-Si复合氧化物具有很高的比表面积，在TiO_2含量为10％时达到681.5m~2／g，Ti原子进入Si-O四面体结构中，形成Si-O-Ti键，复合氧化物的稳定性好，当TiO_2含量低于60 wt％时，以无定型形式存在；当含量为80％时，出现锐钛矿型TiO_2，但与纯TiO_2相比晶型不完整：醋酸对Ti-Si复合氧化物的比表面积、晶型都有很大的影响；TiO_2含量为20％的20TiSi经1100℃高温焙烧后，仍有较高的比表面积(11m~2／g)，稳定性好，在较宽的温度范围内焙烧，没有引起Ti-O-Si键的断裂，分散度高，没有出现晶型TiO_2。

objective: to investigate the effect to blood platelet and brain natriuretic peptide of danhong injection on the unstable angina.

Aim:To study the relationship between restenosis and the changes of nitric oxide and noradrenaline before and after the coronary artery stent implantation. Methods: The serum levels of NO and NA before and after the CASI in 21 patients with unstable angina were measured.

目的：观察不稳定型心绞痛患者经皮冠状动脉腔内支架植入术支架植入前后血浆中一氧化氮和去甲肾上腺素浓度的变化，探讨其在经皮冠状动脉腔内支架植入术术后再狭窄发生中的作用。

The term "program" is not intended to connote complete rigidyty.

"程序"这个词不含有完全定型的意思。

Objective To observe treatment efficacy and safety of unstable angina treatment with consociation of aspirin and Plavix.

目的 观察氯吡格雷与阿斯匹林联合应用治疗不稳定型心绞痛的临床疗效及安全性。

Methods: 60 patients with unstable angina pectoris were randomly divided into depside salt from Salvia Miltiorrhiza group and Danshen Injection control group. Every group was treated for 14 days. The changes of blood platelet packingfraction and MMP-9 in the two groups were observed.

将 60例不稳定型心绞痛患者随机分为丹参多酚酸盐治疗组及常规治疗组，均治疗14 d，观察两组治疗前后血小板聚集率、MMP-9表达变化情况。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
