並依據課題研究的特點，將文章的主體分為三大部分，即關于油田地面工程設備經濟壽命、大修理和設備更新的經濟評價方法研究三部分。 -
The knowledge of these initial collision is crucial for any theoretical treat - ment of a possible parton - hadron phase transition, the detection of which being the ultimate aim of all the efforts of co1liding heavy ions at very high energies. the parton model allows to calculate inclusive cross sections as a convolution of any elementary cross section with parton distribution functions, assuming that factorization works. the disadvantage is that tlle first interaction is coilsidered quite differently from the subsequent ones in case of multiple scattering
其它的弦模型在計算幾率時，忽略了入射能量在pomeron之間的分配，破壞了能量守恆，而且把pomeron作為全同粒子處理，即pomeron之間是不可區分的；然而在處理粒子產生時，這些模型雖然考慮了能量守恆，但是第一個pomeron的粒子產生與其它的pomeron很不一樣? ? pomeron在粒子產生時不是全同的。 -
It is a non - propelled crane ship after conversion, operating in ports and calm waters, deploying towing in chinas coastal class ii navigational area and suitable for salvage of sunken ships, harbour construction, lifting of bridge beams sections for erection, loading unloading heavy cargoes as well as offshore oil drilling production platform and other offshore hook - up

Standard specification for high strength steel castings in heavy sections
重型型鋼中高強度鋼鑄件的標準規范 -
Body : body is cast with heavy sections reinforced at points subjected to the greatest stress. valves are available in both flanged and butt welding ends. all conform to asme specifications
閥體：閥體為鑄件，在關鍵點上通過重型型鋼加以強化，能夠承受更大的應力。這些閥門都可配置法蘭連接埠和對焊連接埠，都符合asme標準。 -
1 noise : the greatest volume of noise normally occurs on straight sections when trains pass at their highest speed. whereas noise from mrt trains is masked by the background noise of heavy daytime traffic, at nighttime the level of noise is significantly more obvious
（ 1 ）噪音部分：捷運直線高速行駛路段之噪音最高，因日間交通量大，道路交通噪音亦大，故捷運音量較不明顯，于夜間捷運車輛行駛之噪音則較明顯。 -
Insufficient material in the mould to prevent excessive shrinkage due to heavy sections, ribs, bosses
防止由於厚部位，加筋和凸出部位的收縮，產生的模腔中材料不足 -
1 noise : the greatest volume of noise normally occurs on straight sections when trains pass at their highest speed. whereas noise from mrt trains is masked by the background noise of heavy daytime traffic, at nighttime the level of noise is significantly more obvious. on curved sections and cornered sections and on sections close to stations, the impact of noise on the neighborhood is much lower
以列車行進于地下隧道段時，輪軌滾動噪音經封閉空間所傳回車廂，使乘客感受到的噪音，與列車行駛于平面、高架及出土段時，沿線非乘客感受到的移動式空傳噪音最為迫切有待解決之課題；
