ratio by volume

And then the free vibration, the throttle orifice diameter and the volume ratio between the two attaching gas chambers of air spring with series double attaching gas chambers are researched in detail by the numerical simulation method.

以此为基础，利用数值计算的方法对串联双附加气室空气弹簧的自由振动、节流孔大小及两附加气室容积比对弹簧的影响进行了细致研究。

Trifluoroacetic acid ( TFA) was used as the retaining acid and ammonia liquor as the eluent base. The solvent system was n-hexane-acetic ester-methanol-water ( ratio by volume was 9 ∶ 1 ∶ 5 ∶ 5).

采用三氟乙酸做为保留酸，氨水作为洗脱碱，溶剂系统为正己烷/乙酸乙酯/甲醇/水（体积比为9∶1∶5∶5）。

This paper studies performance of modified asphalt mortar changing with volume of modifier and filler-asphalt ratio by performing the high-temperature penetration test and low-temperature creep test.

为了研究矿粉对沥青老化性能的影响，采用旋转薄膜烘箱试验模拟胶浆的老化，测试了不同老化状态时沥青胶浆的高、低温性能。

Platelet-rich plasma gel was prepared by compounding platelet-rich plasma and bovine thrombin solution in the volume ratio of 6 to 1. ④ The prepared platelet-rich plasma gel was lyophilized, and then was observed grossly and by scanning electron microscopy.

制备富含血小板血浆凝胶：将富含血小板血浆与牛凝血酶溶液按体积比6∶1充分混合为凝胶。④冻干及观察：将富含血小板血浆凝胶冻干，进行大体观察和扫描电子显微镜检查。
