保护性

I designed a couple of boats for Abbate, a 60' first then a few years later a 70', they were open day boats… well not really the 70' wasn't a classis open , it already sported a protective spray screen just forward of cockpit, which grew in time becoming increasingly visible paving the way for the modern screen tops of today that practically close the boat off.

我为 Abbate 设计了两艘船，一艘60英尺，几年后又设计了一艘70英尺的船。两艘船都是开放式船只。70英尺并不是经典意义上的开放式船只，但那时我就在驾驶舱前面安装了保护性的防水屏幕，可以说这为现代封闭性船只使用的船舱屏风铺平了道路。

Major outer membrane protein encoded by omp1 gene is the major protective protein of Chlamydophila abortus.

Objective To study the synergic effect of praziquantel and host acquired immunity on Clonorchis sinensis.

研究吡喹酮与宿主保护性免疫对华支睾吸虫感染的协同作用。

Both the passive transformation and active immunity of MS1-5 are effective in mediating protection on imunlzed mice.

进一步研究表明MS1-5均是保护性抗体，能抑制SP侵入肝细胞，中和SP感染力，无论是抗体的被动转移还是主动免疫均能使受者获得一定的抗感染力。

Aiguillette double high-density air-filled sponges, soft, comfortable, and provided a good shoulder protection.

All this is probably an air pocket; overall economic output almost certainly began to rise in the third quarter of the year and employment will eventually follow.

这一切或许是如"气囊"一般的保护性反应；今年第三季度，经济总量确已开始上升，就业率最终也将随之跟进。

In addition, access control policies of aggregated resources can be formulated as expressions of the algebra. Several algebraic properties of policy expressions are discussed. It shows that the algebraic properties of policy expressions can be used to verify whether policy composition results meet the protection needs of each party.

用代数表达式形式化地描述聚合资源的访问控制策略，讨论了策略表达式的若干代数性质，说明可借助策略表达式的代数性质去验证策略合成结果是否符合各方对聚合资源的保护性需求。

The results showed that different tillage patterns could improve soil water storage,the soil laer of no-tillage was covered by straws between 0 to 20 cm held water(4.542±0.894)×10~5 L/hm~2;Under no-tillage with full-straw mulching average soil temperature at 0～20 cm decreased...

结果表明：不同的保护性耕作措施均可提高土壤水分含量，其中留茬旋耕处理的土壤贮水量最高，达(4.542±0.894)×105L/hm2；在玉米播种前期及苗期，免耕覆盖处理降低土壤温度1~2℃，而整个生育期留茬旋耕处理与传统耕作处理的土壤温度相近；苗期，留茬旋耕处理的玉米株高、根长、鲜重和干重均优于其它处理，促进了玉米的生长发育；不同的保护性耕作措施均可提高玉米的产量，与传统耕作相比可增产

The results showed that different tillage patterns could improve soil water storage, the soil laer of no-tillage was covered by straws between 0 to 20cm held water (4.542±0.894)×10^5L/hm^2 Under no-tillage with full-straw mulching average soil temperature at 0~20cm decreased 1~2℃ during early corn growing period; In early season of corn growth, minimum-tillage with 1/3-straw mulching would promot the growth; Compared with the conventional tillage, economic yields could increase

Objective To investigate the effect and side-effect of mifepristone in small doses comparing C53contraceptive in postcoital contraception.Methods 142women with normal menstruation were divided into two groups randomly.Observation group（n=66）were given mifepristone10mg and C53contraceptive5mg within72hours after unprotected intercourse or contraception failure.Control group（n=76）were given mifepristone with a sin-gle dose of10mg within72hours after unprotected intercourse or contraception failure.The effect side-effect and menstruation of the two group were compared.

目的 探讨低剂量米非司酮配伍双炔失碳酯应用于紧急避孕的效果方法将142例月经规律的合格妇女随机分 2组，观察组（66例）在避孕失败或无保护性性交后72h内开始服用米非司酮10mg+双炔失碳酯5mg，对照组（76例）在避孕失败或无保护性性交后72h内开始服用单剂量米非司酮10mg，观察两组避孕效果、不良反应及月经情况。
